Description

Profile top bending machine and profile top bending forming method

technical field

The invention belongs to the field of profile processing equipment, and in particular relates to profile bending processing equipment.

Background technique

Existing profile bending usually adopts the roll forming method and its roll forming equipment. The profile bending forming principle is that two self-rotating rollers drive the profile forward, and the other roll moves along a straight line to bend the profile. However, with the development of technology, the size of the curved profiles required is getting larger and larger, which makes the roll forming method more and more inadequate and difficult to apply.

Specifically, when the size of the profile is large, using the existing bending forming method, the self-rotating roller needs a huge torque to drive the profile forward, but in reality this huge torque is difficult to obtain, or the implementation cost is high ,Uneconomical. Moreover, the existing profiles are not limited to one-way bending, and it is difficult to apply the roll-bending method to profiles that require multi-directional bending. This is because the bending deformation of the entire profile needs to be continuously transmitted forward. When there is a bending arc in another direction, it is obviously difficult to transfer and obtain effective bending in the current roll forming equipment.

Detailed ways

Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

In order to realize high-quality and high-efficiency processing of profiles (especially large-size and large-size profiles), the present invention provides a new type of profile top bending machine for top bending of profiles, which can realize top bending of profiles with variable curvature in multiple directions .

In a specific manner shown in Figures 1 to 10, the profile bending machine includes:

The fixed truss 100 is formed with a profile accommodation space S along the length direction L of the truss in the fixed truss 100;

A plurality of curved cages 300 are arranged at intervals along the length direction L of the truss, and the curved cages 300 are fixedly installed on the fixed truss 100 and used to fix and hold the profile 1000; and

Multiple sets of push plate mechanisms are arranged at intervals along the length direction L of the truss and are fixedly installed on the fixed truss 100. Each set of push plate mechanisms includes profile push plate mechanisms distributed on both sides of the profile 1000 to push the profile 1000 toward each other. And push the push plate mechanism.

Among them, the profile top bending machine of the present invention adopts a multi-point quantitative pushing method, which avoids the large torque required by the existing top bending machine, and multiple groups of pushing plate mechanisms are arranged at intervals along the length direction of the profile. The push plate mechanisms on both sides of the profile can realize forward and reverse bending of the profile 1000. During the top bending operation, one of the push plate mechanisms on both sides is the profiling push plate mechanism, and the other is the push plate push mechanism. The profiling push plate mechanism presses against, pushes and leans against each other, and pushes according to the construction method, so as to realize one-time, large-torque cold bending of profiles, which will be described in detail below.

Wherein, the construction method mentioned refers to the required advancing distance of each push plate mechanism when the profile is bent to the target curve shape. The present invention performs top-bending on the profile 1000 through multiple sets of push plate mechanisms, which can effectively solve the problem of inability to obtain huge rotation torque during roll-bending in the prior art, and make cold-bending of large-scale profiles feasible.

As shown in FIGS. 1 and 2 , the fixed truss 100 as a gantry mechanism is used to provide a good clamping foundation and a force application foundation for the top bending of the profile, and plays an important supporting role. The fixed truss 100 can be welded by H-shaped steel, has its own good stability, and can withstand relatively large forces.

In a specific structure shown in FIG. 2 , the fixed truss 100 has a rectangular cross section and includes four long side columns 101 extending along the length direction L of the truss, and the fixed truss 100 is divided into a plurality of truss units along the length direction L of the truss, Each truss unit includes truss beams 102 connecting adjacent long side columns along the truss width direction W and truss columns 103 connecting adjacent long side columns 101 along the truss height direction H. In FIG. 2 , in order to provide more stable support, the fixed truss 100 further includes truss bracing mechanisms 104 arranged on both sides in the width direction W of the truss.

The fixed truss 100 adopts modular configuration, that is, it is divided into multiple truss units along the length direction L of the truss, so as to be suitable for multi-point clamping and multi-point torsion distribution of profile top bending, and can adapt to profiles of different lengths. The lengths of each truss unit can be the same or different, depending on the distribution of thrust action points determined by the specific bending and forming requirements of specific profiles.

Similar to FIG. 2, the fixed truss 100 used in FIG. 1 also has a rectangular cross section and includes four long side columns 101 extending along the length direction L of the truss. The fixed truss 100 is divided into a plurality of truss units along the length direction L of the truss, each Each truss unit includes a truss beam 102 connecting adjacent long side columns 101 along the truss width direction W and a truss column 103 connecting adjacent long side columns 101 along the truss height direction H. Due to the balanced force along the width direction of the truss during the top bending process, the fixed truss 100 in this embodiment does not have the truss bracing mechanism 104 shown in FIG. Stable and reliable. Similarly, the fixed truss 100 can be welded with H-shaped steel to form a gantry structure, and adopts modular configuration, which can adapt to the adjustment needs of profiles 1000 of different lengths and multi-point push arrangement.

The function of the bending cage 300 is to prevent the profile from twisting and deforming when it is bent. A curved cage 300 with a reasonable structure and its clamping structure are designed for the profile 1000 to be fixed and clamped. First, in the clamping orientation, in the present embodiment shown in FIG. 1 , taking the profile 1000 of the H-shaped plate structure as an example, the curved cage 300 fixes and holds the profile 1000 along the height direction H of the truss, and the push plate mechanism is arranged on the truss Both sides in the width direction W. Of course, when the fixed truss 100 is suspended, the curved cage 300 can also be fixed to hold the profile 1000 along the width direction W of the truss, and the push plate mechanism is arranged on the upper and lower sides of the height direction H of the truss.

Likewise, the profile 1000 in the illustrated embodiment adopts an H-shaped plate and includes a web 1001 and flange plates 1002 extending from both lateral sides of the web 1001 along the thickness direction of the web. Of course, this is only an example, and the profile bending machine of the present invention is not limited to processing H-shaped plates. The profiled plates can be "eccentric I" or "non-eccentric I", or other shapes such as T-shaped plates, etc. It only needs to adjust and design the fixed and holding structure of the corresponding curved cage for different shapes of profiles.

Taking the H-shaped profile as an example, according to the bending direction of the H-shaped profile, it can generally be divided into vertical bending and flat bending. Referring to Fig. 7, flat bending means that the web 1001 is parallel to the horizontal plane, that is, after entering the mold, the web 1001 of the profile 1000 loaded into the fixed truss 100 is parallel to the width direction W of the truss, and the thrust direction of the push plate mechanism is along the width direction W of the truss Acts on profile 1000. Referring to Fig. 8, the vertical bending is that the web 1001 is perpendicular to the horizontal plane, and the vertical bending direction is perpendicular to the horizontal bending direction. After the profile is put into the mold, the web 1001 is placed along the height direction H of the truss and perpendicular to the width direction W of the truss, while the thrust direction of the push plate mechanism still acts on the profile 1000 along the width direction W of the truss.

For different structures of flat bending and vertical bending, different structural forms of the curved cage 300 are designed. Referring to Fig. 7 to Fig. 10, the curved cage 300 can include or be divided into a flat curved cage and a vertical curved cage, and the profile 1000 can be clamped and fixed to the fixed truss 100 in different installation orientations through the vertical curved cage and the flat curved cage. Inside, so that cold bending in different directions can be realized.

Referring to Fig. 7 and Fig. 9, in a specific structure, the flat-curved retaining bracket includes:

The flat-bending support bracket includes supporting vertical bars 301 on both sides and flat-bending supporting rollers 302 placed laterally between the supporting vertical bars 301 on both sides. the underside of the web; and

The flat bending crimping part 303 is placed horizontally and the two ends are fastened to the supporting vertical rods 301 on both sides by crimping fasteners 800 (such as rotatable and adjustable fastening bolts, etc.) with adjustable crimping strokes. At the top end, the flat-bending crimping part 303 is formed with a web holding part 3031 arranged in alignment with the flat-bending support roller 302 , and the web holding part 3031 is suitable for pressing against the top surface of the web of the profile 1000 .

The flat-bending holding bracket shown in the figure can better support the web 1001 up and down, so that the web 1001 is not prone to unnecessary twisting deformation, wrinkling deformation, etc. during the bending process. The flat bending supporting roller 302 can roll and convey the profiles, and the height and position of the flat bending supporting roller 302 can be adjusted to be suitable for profiles 1000 of different sizes. Both ends of the flat-bent crimping member 303 can be fastened to the top of the support vertical bar 301 with a certain pre-load by fastening bolts, so as to securely fix the profile 1000 .

Referring to Fig. 8 and Fig. 10, in a specific structure, the vertical bend retaining bracket includes:

The vertical bending support bracket includes support vertical bars 301 on both sides and vertical bending support rollers 304 placed laterally between the support vertical bars 301 on both sides. The vertical bending support rollers 304 are suitable for abutting against the support profile 1000 the bottom flange; and

The vertical bending crimping part 305 is placed horizontally and its two ends are fastened to the top ends of the supporting vertical rods 301 on both sides by crimping fasteners 800 with adjustable crimping strokes.

Similarly, the vertical bend holding bracket shown in the figure can vertically fix and clamp the upper and lower flange plates 1002 , and apply a certain vertical pressing force through the fastening bolts at both ends of the vertical bend crimping part 305 .

Further, referring to Fig. 8, a fixed limit stop 3051 for blocking the flange plate 1002 on both lateral sides can also be added on the vertical bending crimping part 305, furthermore, the fixed limit stop 3051 The lateral mounting position on the crimping part 305 can be adjusted.

It should be noted that, the two structural forms of the curved cage 300 shown in the accompanying drawings are only examples, and different structural designs can be made according to different profiles.

The curved cage 300 is preferably detachably installed in the fixed truss 100 for easy disassembly, position adjustment and the like. After determining the target curve shape of the required profile top bending, the curved cage 300 can be selected and each curved cage 300 can be fixedly installed on the corresponding truss units, that is, the length of the truss length direction L of the fixed truss 100 in different positions. In the illustrated embodiment, the curved cage 300 is detachably mounted on the fixed truss 100 through a plurality of fastening bolts of the top frame and the bottom frame.

At least one set of push plate mechanism is installed on each truss unit, that is, the profile push plate mechanism and the push push plate mechanism on both lateral sides, both of which include:

The pushing unit, preferably a large thrust hydraulic thrust mechanism 400, is fixedly installed on the truss column 103 and used for telescopic driving along the width direction W of the truss; and

The push plate 600 is used to push the profile 1000 under the drive of the hydraulic thrust mechanism 400 .

In this embodiment, the pushing unit adopts hydraulic power, that is, the hydraulic system provides a huge thrust for the cold bending of the profile. Those skilled in the art know that the hydraulic system can be composed of oil cylinders, hydraulic stations, signal devices, etc., to provide the bending force for the lifting machine. The forward thrust is provided by the oil cylinder of the jack bending machine, and the forward distance of the oil cylinder is controlled by the signal device. The composition and structure of the hydraulic thrust mechanism 400 and its control and propulsion are not the key of the present invention and are known technologies, so they will not be repeated here. Of course, as mentioned above, the pushing unit of the present invention is not limited to hydraulic power, and cylinders, electric thrust mechanisms, etc. can also be used to replace or assist.

In a specific structural form shown in FIG. 3 , the push plate 600 includes:

The push plate mounting frame 601 is used to be installed on the truss beam 102 and can move along the truss beam 102 under the drive of the hydraulic thrust mechanism 400;

The pressing roller part 602 protrudes laterally from the push plate mounting frame 601 to position against the pressing profile 1000; and

The profile clamping parts 603 are respectively arranged on the upper and lower sides of the pressing roller part 602 , and the profile clamping parts 603 protrude laterally from the push plate mounting frame 601 to clamp and fix the profile 1000 .

Wherein, the upper and lower ends of the push plate mounting frame 601 can be slidably installed between the truss beams 102, and a guide rail slider structure along the width direction W of the truss can be arranged between them. The pressing roller portion 602 can be used not only as a pushing force application member during vertical bending, but also as a positioning member for positioning against the web 1001 during vertical bending. The profile clamping part 603 is used for clamping the flange plate 1002 in vertical bending and serves as the main push force component.

In order to be suitable for different profiles 1000 , the profile clamping part 603 is preferably installed on the push plate mounting frame 601 in a vertically adjustable manner. More importantly, the height and position of the profile clamping part 603 can be adjusted, so that the profile 1000 that has been bent and deformed in one direction can be bent and deformed in the other direction, and the profile can be bent in one direction or bent in multiple directions. . For example, when the profile after flat bending is subjected to vertical bending operation, the height position of the flange plate 1002 along the length direction of the profile is uneven. At this time, the height position of the corresponding profile clamping part 603 can be adjusted adaptively, so as to complete Multi-direction continuous top bending operation of profile 1000.

FIG. 4 shows a schematic plan view of the push plate 600 installed in the fixed truss 100 . Wherein, the push plate 600 and the curved cage 300 are fixedly installed on different positions of the fixed truss 100 along the length direction L of the truss. Referring to FIG. 7 and FIG. 8 at the same time, the push plate 600 is arranged between two adjacent curved cages 300 Therefore, FIG. 4 only shows a schematic plan view of the installation position of the push plate 600. The hydraulic thrust mechanism 400 laterally pushes the push plates 600 from both sides in the width direction W of the truss to apply bending thrust.

Referring to FIG. 4 , the hydraulic thrust mechanism 400 includes an outer shell portion 401 , and may also be provided with an electronic reading scale 403 and/or a mechanical reading scale 404 for measuring the telescoping stroke of the push rod portion 402 , so as to facilitate automatic measurement and manual review.

In order to facilitate the delivery of the profile 1000 and its entry and exit from the mold, the profile bending machine includes transmission brackets 700 arranged at both ends of the fixed truss 100 along the length direction L of the truss. Referring to Fig. 5 and Fig. 6, in a specific structural form, the transmission bracket 700 includes:

The outer door arch frame includes outer door arch struts 701 on both sides of the lateral interval, and the respective top ends of the two outer door arch struts 701 extend laterally toward each other with flat and curved drive rollers 702; and

Wherein, the vertical bending drive roller 704 is arranged directly below the transverse interval space of the two horizontally spaced flat bend drive rollers 702 , and the transverse width of the transverse interval space is smaller than the profile width of the profile 1000 and greater than the profile thickness.

In this way, the transmission bracket 700 of the above-mentioned structure is placed at both ends of the fixed truss 100 at intervals, which can facilitate the transportation of the profile 1000, and can be directly turned over on the transmission bracket 700 after the profile 1000 has been bent flat. state.

Based on the above profile top bending machine, the present invention also provides a corresponding profile top bending forming method. Referring to Fig. 11, the profile top bending forming method includes the top bending forming steps:

According to the target curve line shape after the top bending of the profile, push each profiling push plate mechanism on the same side into place according to the target line shape construction method value, and push each push plate push mechanism on the other side to the respective corresponding profile Push plate mechanism, so that the profile is bent and formed.

Among them, after each profiling push plate mechanism on the same side is pushed into place according to the target linear construction value, each push plate is arranged to form a profile with a certain radian, and at this time, the profile is bent toward the profile by pushing the push plate mechanism. Then the preset profile bending can be realized and the ideal target curve shape can be obtained.

Among them, after the top bending operation, measurement and comparison can also be carried out until the target curve shape is obtained.

Obviously, according to the profile top bending machine and the profile top bending method of the present invention, not only the operation is efficient, the operation cost is low, and the precision is controllable, but also the variable curvature top bending of different length regions of the profile 1000 can be performed.

Furthermore, it is not only possible to carry out single-directional top bending on the profile 1000, such as the above-mentioned flat bending operation or vertical bending operation, but also to perform multi-directional top bending on the profile 1000, for example, the same profile 1000 can be sequentially realized on the same profile top bending machine Flat bends and vertical bends. At this time, the profile top bending forming method includes:

First lay the profile 1000 horizontally and send it into the fixed truss 100, and complete the flat bending forming through the above-mentioned various top bending forming steps;

Then the profile 1000 formed by flat bending is turned vertically around the length direction of the profile and placed vertically, and sent into the fixed truss 100 to repeat the above-mentioned steps of top bending, and then the vertical bending is formed.

Wherein, when the vertical bending operation is performed after the flat bending is completed, it is necessary to adjust the height of the plywood of each profile clamping part 603 to adapt to the flat bending line of the profile and securely clamp the profile.

Furthermore, whether the push plate mechanism adopts a hydraulic system or a motor reducer mechanism, its signal device is replaced with a corresponding sensor device to collect and monitor the position of the profile 1000 during the top bending process in real time, and the top bending process can be automated. control.
