Abstract
The invention relates to a tensioning method for an inner-tension prestressing element, which comprises the following steps: a processed unit or work piece is arranged on a platform and then fast pressed or clamped by a pressing board or a hydraulic pressure grip after position adjustment; a steel wire is inserted into a pipe sealed at one end; an end steel plate at the other end of the pipe is connected with the steel wire beaded with an end sealing ring; the steel wire is connected with a buckle of a steel wire on the hoisting cylinder of the inner tension prestressing element and is tensioned to lead the steel wire on the hoisting cylinder into the chute of each guide wheel. The tensioning method for the inner-tension prestressing element has the advantages that the ropes of odd-formed cross section or complex odd-formed cross section can be easily tensioned to get the inner-tension prestressing elements; and the need is met to deal with different cross-sectional areas and different materials such as steel, stainless steel, alloy, aluminum alloy and other materials.
Description
Technical field
The present invention relates to metal material stretch-draw field of mechanical technique, a kind of specifically internal tension prestressed component tensioning method.
Background technology
Present cement prestressed girder adopts is to put into the reinforcing bar that needs quantity in the hole in beam, one of reinforcing bar welds with steel plate, the other end reinforcing bar penetrates in the hole of steel plate, then reinforcing bar is carried out electrical heating, be heated to the temperature of requirement after, steel plate and reinforcing bar are welded, after treating the reinforcing bar cooling, reinforcing bar shrinks and produces prestressing force, but " inner stretching prestressed super-light structural " carried out special-purpose machinery and the method that prestressing force is processed, and China does not also have at present.
Summary of the invention
The objective of the invention is to develop a kind of internal tension prestressed component tensioning method that " inner stretching prestressed super-light structural " is carried out prestressing force processing.
Internal tension prestressed component tensioning method of the present invention is that work piece one end and stretching wire rope are fixed together, and the continuous other end to steel wire rope applies external force, when pulling force reaches the numerical value of regulation, secures with end socket spare, makes work piece produce prestressing force.Its method is as follows:
1, processed good unit or workpiece, is contained on the platform, adjusts the position and compress or clamp with pressing plate or hydraulic chuck;
2, in pipe, penetrate steel wire rope, and the one end is secured;
3, the termination steel plate of the other end of pipe fitting and steel wire rope are worn linked up;
4, on steel wire rope, penetrate the end-blocking ring;
5, the buckle of the steel wire rope on the winding drum of steel wire rope and inner stretching prestressed component stretching device is coupled together and tensioning, the steel wire rope on the winding drum is entered in the groove of each guide wheel;
6, press the method for operating startup converter plant of inner stretching prestressed component stretching device, the driven by motor winding drum is rotated, steel wire rope begins stretch-draw;
7, carry out stretch-draw and reach the power of regulation after, flatten the end-blocking ring with forcing press, the inner stretch-draw prestressing force on the steel wire rope is remained in the pipe fitting, reverse motors is taken off buckle, cuts unnecessary steel wire rope;
8, unclamp pressing plate or hydraulic chuck, take out workpiece;
9, check, qualified, warehouse-in.
The advantage of internal tension prestressed component tensioning method of the present invention is: the rope in special-shaped section or the very complicated special-shaped section is carried out the stretch-draw ratio be easier to, make it to obtain the inner stretch-draw prestressing force member, this internal tension prestressed component tensioning method adapts to the needs of different cross section, unlike material processing, as steel, stainless steel, copper alloy, aluminium alloy etc.
The specific embodiment
A kind of internal tension prestressed component tensioning method, its method is as follows:
1, processed good unit or workpiece, is contained on the platform, adjusts the position and compress or clamp with pressing plate or hydraulic chuck;
2, in pipe, penetrate steel wire rope, and the one end is secured;
3, the termination steel plate of the other end of pipe fitting and steel wire rope are worn linked up;
4, on steel wire rope, penetrate the end-blocking ring;
5, the buckle of the steel wire rope on the winding drum of steel wire rope and inner stretching prestressed component stretching device is coupled together and tensioning, the steel wire rope on the winding drum is entered in the groove of each guide wheel;
6, press the method for operating startup converter plant of inner stretching prestressed component stretching device, the driven by motor winding drum is rotated, steel wire rope begins stretch-draw;
7, carry out stretch-draw and reach the power of regulation after, flatten the end-blocking ring with forcing press, the inner stretch-draw prestressing force on the steel wire rope is remained in the pipe fitting, reverse motors is taken off buckle, cuts unnecessary steel wire rope;
8, unclamp pressing plate or hydraulic chuck, take out workpiece;
9, check, qualified, warehouse-in.
