[0002] Stamping relies on a press and a die to apply external force to a sheet metal, etc., so that it undergoes plastic deformation to obtain the required shape. With the development of industry, the conventional part shapes no longer meet people's needs. Therefore, it is necessary to manufacture special-shaped parts according to the usage requirements to make them more in line with the usage needs and increase the service life of the parts. For special-shaped parts, special stamping dies are required to process raw materials.

[0003] The existing document CN219581443U - a stamping die for processing special-shaped parts includes a bottom plate. One end of the upper surface of the bottom plate is fixedly installed with a first cylinder. The upper surface of the bottom plate is fixedly installed with a lower die base beside the first cylinder. The upper surface of the lower die base is threadedly installed with a lower die. One end of the upper surface of the bottom plate perpendicular to the first cylinder is fixedly installed with a vertical plate. A threaded rod is threadedly installed in the vertical plate. The upper surface of the vertical plate is fixedly installed with a second cylinder. The output end of the second cylinder is fixedly installed with an upper die base. Through the mutual cooperation of the threaded rod and the clamping plate, the threaded rod is rotated to make the clamping plate and the baffle approach each other to fix the sheet metal, increasing the safety of the work and preventing workers from being injured. And through the mutual cooperation of the first cylinder and the electric push rod, the processed sheet metal is first ejected by the electric push rod and then pushed into the collection box by the first cylinder, facilitating the taking out of the sheet metal and increasing the working efficiency of the processing. However, it still has the following disadvantages in actual use:

[0004] 1. For the above-mentioned stamping die for processing special-shaped parts, when the first cylinder pushes the processed special-shaped part into the collection box, the push plate contacts the special-shaped part during the pushing process, which is easy to damage the special-shaped part, resulting in the part being unusable and causing material waste;
