Wedge mechanism

Abstract

The invention discloses a wedge mechanism which comprises a sliding trolley, a movable mounting seat, an upper die body mounting seat and a lower die seat body. A lower driving block is arranged on one side of the sliding trolley, an upper driving block matched with the lower driving block is arranged on one side of the movable mounting seat, and a side guide plate is arranged on the side, opposite to the upper driving block, of the movable mounting seat. The upper die body mounting seat is provided with an upper die cushion block, the upper die cushion block is located above the movable mounting seat, and the upper die cushion block can transmit pressure downwards to the movable mounting seat to drive the upper driving block to move downwards. An elastic element is arranged on the lower die seat body and located below the movable mounting seat, and the elastic element can jack up the movable mounting seat. The wedge mechanism prevents the upper die body mounting seat from bearing lateral force, the overall intensity of the upper die body mounting seat is improved, and mounting space is saved.

Description

technical field [0001] The invention belongs to the field of automobile stamping dies, in particular to a wedge mechanism. Background technique [0002] With the continuous development of the car industry, there are more and more car models, and the assembly process of the body-in-white is becoming more and more complicated. The outer cover parts of many models, such as side panels, fenders, top covers, hood outer panels, etc., are mainly designed with negative angles to achieve the purpose of increasing the bite force of stamping parts and improving the strength of the body, while the body The negative angle flanging of the part will increase the complexity of the mold structure accordingly. In order to take out the stamping parts smoothly after the negative-angle flange shaping is completed, a slider-type wedge mechanism is generally used in the mold structure, that is, the part of the die with negative-angle flange shaping is made into a pulley mechanism, and the rollove...

AI Technical Summary

Problems solved by technology

[0009] (1) The height from the mounting base to the bottom of the upper die base is too high, the pulley is driven by lateral force, and the strength of the mounting base is not good;

[0010] (2) The installation seat is too high, and the upper die seat is uncoordinated as a whole, which is not conducive to processing and manufacturing;

[0011] (3) The body of the upper drive block mounting seat and its reinforcing ribs are relatively large in cross section, which will occupy more work space. For molds with complex structures such as side walls and fenders and many work contents, there will be interference of working mechanisms and space Insufficient problem of not being able to install
