Description

Stamping die hanging wedge Technical Field The utility model relates to the field of die structures, in particular to a lifting wedge of a stamping die. Background In the manufacture of vehicle parts, the blank is fed into a stamping continuous die, and is sequentially subjected to multi-pass continuous stamping deformation, so that the automobile parts with complex shapes are finally formed. The hanging wedge is one of mechanical structures in the stamping progressive die, the common hanging wedge is a wedge, the wedge moves along the inclined plane of the wedge, other parts which are in contact with the wedge are driven to move, and finally the work of adjusting the phase positions of the two parts is realized. Generally, the hanging wedge is contacted with other parts through the working surface which is inclined integrally, but as the working time is prolonged, the lubricating oil loss is accelerated, the friction on the working surface is increased, the contact area of the working surface is large, the working surface is easy to wear, the reduction is carried out, and the processing precision of the die is further affected. It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the present disclosure and thus may include information that does not constitute prior art known to those of ordinary skill in the art. Disclosure of utility model Aiming at the defects of the prior art, the utility model discloses a lifting wedge of a stamping die. The technical scheme adopted by the utility model is as follows: The stamping die hanging wedge comprises a driving block, wherein an inclined driving surface is arranged on the bottom surface of the driving block, the stamping die hanging wedge comprises a guide block, an inclined guide surface is arranged on the top of the guide block, telescopic columns are movably connected in the guide block and are obliquely arranged, the driving surface is contacted with the top of the telescopic columns, and when the driving block is pressed down to the limit position, the driving surface is contacted with the guide surface. Furthermore, an inclined through hole I is formed in the guide block, and the telescopic column is located in the through hole I. Further, the outside of flexible post is provided with the external member, the upper portion of through-hole one is provided with the cavity, the external member is located the cavity. Further, the top of the telescopic column is provided with an outwards extending flange, and the top of the sleeve abuts against the flange. Further, a step part is arranged at the inner edge of the top opening of the sleeve, and the flange is positioned in the step part Further, the telescopic column is penetrated with a fixing key, and the fixing key penetrates through the sleeve Further, the device comprises an upper die pressing plate, wherein a second through hole is formed in the upper die pressing plate and is arranged in the thickness direction of the upper die pressing plate, and the driving block is movably arranged in the second through hole. Further, the die comprises an upper die, wherein the upper die is provided with a positioning groove, and the guide block is arranged in the positioning groove. The beneficial effects of the utility model are as follows: 1. In the use of the die, the driving block is pressed down in the upper die pressing block, the driving surface of the driving block is contacted with the top of the telescopic column, the telescopic column is driven to move towards the inside of the die, the telescopic column finally abuts against a part in the die cavity of the die, and when the driving block moves to the limit position, the driving surface of the driving block abuts against the guiding surface of the guiding block, and as the driving block is contacted with the telescopic column, the contact area of the working surface is greatly reduced, the abrasion of the driving block is reduced, the movement stability of the hanging wedge is ensured, and the influence on the processing precision of the die is avoided. 2. The external member moves along with the telescopic column, avoids telescopic column direct contact through-hole an inner wall, reduces the friction loss of telescopic column. 3. The flange joint of flexible post is in step portion, and both mutual constraint is being locked through the location between external member and the flexible post, avoids flexible post to float at will, guarantees flexible post motion precision. 4. The hanging wedge structure occupies small space and is suitable for moulds of different models. Drawings Fig. 1 is a schematic structural view of a suspension wedge of a stamping die.
