Problems solved by technology

[0002] At present, the bending of the product is usually completed by the edge folding machine, but when bending some products with too long size and large angle resilience, the product is easy to appear, scratch, etc. during the rapid turning process. Scratches, warping and other phenomena, the product yield is not high

Abstract

The invention discloses a stamping die. A lower stripping plate is arranged between an upper die holder and a lower die holder and is capable of moving downwards relative to the lower die holder by the aid of the moving of the upper die holder, and a reset mechanism capable of driving the lower stripping plate to be reset is further arranged between the lower stripping plate and the lower die holder. A first retaining block and a second retaining block are further located at a position on the upper side of the lower die holder away from the upper die holder, a seesaw block matched with the lower stripping plate is arranged on the upper side of the first retaining block freely, and one side of the seesaw block towards the lower stripping plate extends out of the first retaining block and can swing vertically under the action of the upper die holder and the lower stripping plate. The vertical swing of one side of the seesaw block can drive the other side of the seesaw block to abut against and separated from the second retaining block correspondingly. By means of the stamping die, the product outside surfaces can be prevented from being scratched and abraded, bending and rebounding can be reduced, buckling deformation of overlong bend edges during sharp bending can be prevented, and the product yield is well improved.

Description

technical field [0001] The invention relates to the technical field of dies, and specifically provides a stamping die. Background technique [0002] At present, the bending of the product is usually completed by the edge folding machine, but when bending some products with too long size and large angle resilience, the product is easy to appear, scratch, etc. during the rapid turning process. Scratches, warping and other phenomena, the product yield is not high. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a stamping die, which has a simple structure, stable production process, and effectively improves product yield. [0004] The technical solution adopted by the present invention in order to solve the technical problem is: a stamping die, including an upper mold base and a lower mold base arranged up and down, the upper mold base can perform mold opening and closing movement relative to the lower mold base, A l...
