[0002] Auto parts punching dies are key tools in the automobile manufacturing process, used for large-scale cutting of automobile panels, such as processing automobile door panels, body structural parts, engine hoods, etc. This type of mold has the characteristics of high cutting accuracy, fast cutting speed, long service life, and easy maintenance, which is crucial to ensure the quality and production efficiency of automobile parts. The design and production of punching dies need to follow a series of key points, including understanding the tolerance requirements of parts, material properties, punch tonnage and other parameters, performing CAE analysis to optimize the material thinning rate, and testing the stretching effect by padding sandpaper during mold testing. During the use of the mold, proper maintenance and care are also required, such as regular trimming of the mold edge and slowing down wear to ensure the long-term stable operation of the mold. The inability to replace the punch mold will also increase the difficulty of mold maintenance.

[0003] The punch die of the existing automotive parts blanking die cannot be replaced. Since the punch cannot be replaced alone, complex maintenance operations may be required for the entire die, which will increase maintenance costs and time. The inability to replace the punch die means that when the punch is worn or damaged, the entire die may need to be shut down for maintenance or replacement. This will cause production line interruptions and significantly reduce production efficiency. For this reason, we propose an automotive parts blanking die with an easily replaceable punch die.
