Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-face machining apparatus for simultaneously performing machining such as punching on a surface of a work material extending in three directions.

[0002]

2. Description of the Related Art As a device for punching a panel material (1), there is a punching device as shown in FIG. 6, for example. This punching device is a cam driver in which a processing tool, for example, a punching punch (4) is attached to the tip end surface of a passive cam (3) slidably mounted on a lower die (2) and attached to an upper die (not shown). The rear end of the passive cam (3) is pushed at (5) to advance the passive cam (3), and the panel material (1) is punched by the punch punch (4) attached to the passive cam (3). Is to do.

When a plurality of component mounting holes are formed at one time from the side in a work having a surface extending in three different directions, such as a wheel arch of an automobile, using the above hole punching device, as shown in FIG. As shown in FIG. 8, the same number of passive cams (3) are arranged so as to correspond to the punched portions of the work material (6), and these passive cams (3) are directed toward the respective work surfaces of the work material (6). A plurality of cams that are slidably mounted on the lower mold (2) so as to move forward and backward, and a punch punch (4) is attached to the tip of each passive cam (3), and the passive cams (3) are pushed individually to slide. Attach the driver (5) to the upper mold (7). Then, when the upper die (7) is lowered, all the passive cams (3) are slid by the cam driver (5), and the work material (6) is punched by the punching punch (4) attached to the passive cam (3). It is conceivable to simultaneously process a plurality of points of

However, when a plurality of passive cams (3) and cam drivers (5) are installed in a narrow work space such as the inside of a vehicle hall arch, the passive cams at the center are located at the center of the lower die (2) side. (3a) and passive cams (3
b) and will interfere with each other, and cannot actually be combined into one device.

Therefore, conventionally, a punching device having a passive cam (3a) and a cam driver (5a) for punching a center hole, and a passive cam (3b) and a cam driver (5b) for punching holes on both sides are provided. It was divided into a punching device provided and the punching was performed in two steps.

[0006]

The productivity is extremely poor because the work is carried out over a plurality of steps by using two punching devices. Moreover, it requires a large installation space.

The present invention is intended to provide a multi-face processing apparatus capable of simultaneously performing processing such as punching at a plurality of locations with one apparatus.

[0008]

SUMMARY OF THE INVENTION According to the present invention, a central first slide body having both side surfaces inclined so as to intersect each other and a machining tool attached to the tip thereof, and the first slide body on both sides of the first slide body are provided with the first slide body. A plurality of second slide bodies slidably provided in a direction intersecting with the slide direction of the slide body, each of which has a punching tool attached to the tip thereof, a driving unit for moving the first slide body back and forth, It is a multi-face machining apparatus constituted by cam means for slidably engaging both side portions of one slide body and the second slide body, and moving the second slide body forward and backward in conjunction with the first slide body.

[0009]

In the multi-face machining apparatus, when the first slide body is moved back and forth, the second slide body is advanced and retracted by the cam means in conjunction with the movement of the first slide body. Then, when the first slide body is advanced, the multifaces of the workpiece are simultaneously processed by the processing tools attached to the tips of the first slide body and the second slide body.
