It is mainly used for processing automotive side panel reinforcement. It is a die device that processes metal sheets into specific shapes and punches. Blanking refers to separating the sheet material through the die's cutting edge to obtain a blank of the desired shape. Punching is punching out specific shapes and sizes into the blank or sheet material after blanking. It is a pressure processing method that uses a die mounted on a press to apply pressure to the material, causing it to separate or plastically deform, thereby obtaining the desired parts. The blanking and punching die for automotive side panel reinforcement utilizes the up and down movement of the press, through the upper and lower die cutting edges and punching part of the die, to perform blanking and punching operations on the metal sheet, achieving the initial forming of the automotive side panel reinforcement.

[0003] However, traditional blanking and punching dies for side plate reinforcement plates are complex in structure, inconvenient to operate, and have low processing accuracy.

[0035] In this embodiment, the specific implementation steps of an automatic feeding automotive side panel reinforcement blanking and punching die are as follows: The die is transported to the working position and installed and fixed by the hanging ears 6 on the sides of the upper die 1 and lower die 2. External equipment is connected to ensure that components such as the telescopic cylinder 4 can work normally. At the same time, it is confirmed that the power supply and other conditions of the die meet the usage requirements. The automotive side panel reinforcement material to be processed is placed on the side panel die 24 on the top of the die core 12 of the lower die 2, ready for blanking and punching. Since the die has an automatic feeding function, feeding can be carried out according to the operation mode of the specific automatic feeding device. If the automatic feeding device is not specified, it can be briefly mentioned here that the external feeding equipment will place the material in place. The telescopic cylinder 4 is activated to make the upper die 1 move downward.

A stripper plate 18 is provided above the mold core 12, which, together with the stripper cylinder 16, achieves automatic stripping through the lifting block 15, improving production efficiency and reducing manual intervention. A punching cutter 21 is provided below the inner mold 19, and a punching groove 25 is provided on the top of the side plate mold 24. The two work together to achieve precise punching and ensure processing accuracy. The stripper plate 18 has a honeycomb hole array 22 inside, and a hexagonal block array 23 is provided on the top of the mold core 12. Correspondingly The structural design makes unloading smoother and more stable.

During the mold operation, the mold core 12 will not easily shift, ensuring the processing accuracy and stability. Hard rubber has good elasticity and cushioning performance. The main buffer block 3 can absorb the impact force from the front side of the upper mold 1 when the mold is closed, reducing the wear and damage of the mold. The side buffer block 8 can also play a cushioning role on the side of the mold, reducing the impact on the side of the mold and further protecting the mold structure. At the same time, the hard rubber material is durable and can withstand multiple impacts without being easily damaged, extending the service life of the mold.
