The lower end of the A punch passes through the unloading block and extends to the bottom of the unloading block, and the end of the A punch is fixedly connected to the lower die insert.

[0010] Preferably, the unloading block is arranged on the top of the lower template and is located between the lower template and the supporting pad.

[0011] Preferably, the bottom end of the limiting column is mounted on the top of the discharge block.

[0012] The utility model provides a die for punching holes on the end face of special-shaped materials. It has the following beneficial effects:

[0013] (1) The utility model ensures the precise alignment of the upper die clamp and the punch pin fixing plate by guiding the precision guide pillars 1 and 2, places the profiled material to be punched on the lower die and the support block, and the punch pin fixing plate drives the A punch to press down and punch. Due to the special design of the A punch, the punch head can conform to the complex end face of the profiled material during operation, achieving high-precision punching, while reducing the impact and wear on the equipment, thereby improving production efficiency and equipment service life.

[0014] (2) The utility model optimizes the punching process by setting up an A punch, which is a punch with a cross-sectional diameter that gradually decreases at the bottom of the hanging platform, effectively reduces the friction resistance during punching, improves the punching speed and the service life of the mold, and realizes the processing of high-precision hole positions. It also makes the surface of the special-shaped material after punching smooth and burr-free, further improving the product quality. The design of the limit column ensures the precise positioning of the punching, effectively avoiding the offset problem that is prone to occur in the traditional punching process.
