Stamping process: in the continuous stamping die of multi-station progressive die, the workpiece of the nail arranging machine is stamped downwards to complete the calendering and welding processes. However, a small part is still connected with the punching sheet, which carries the stamped and welded workpiece into the ultrasonic surface treatment equipment to remove rust-proof grease and welding slag. Complete the cleaning of flash and burr in the shot peening room.

This is very necessary to avoid short circuit and electrical short circuit when using stamping parts. In the second short-time ultrasonic surface treatment, before the quality inspection of stamping parts, ultrasonic surface cleaning technology is used again to remove the residue left by shot peening. After all the above operations are completed, the stamping parts and blank plates are completely separated and stored separately. The stamping parts with poor quality of the nail arranging machine are put into the waste bin, and the qualified stamping parts directly enter the packaging workshop.

In the production process, how to avoid the damage of stamping parts is summarized as follows:

1. Reforming stamping equipment to improve production safety and reliability. At present, there are many unsafe factors in the control system and electrical control system of many old stamping equipment. If you continue to use it, you should carry out technical transformation. The manufacturer of stamping equipment should improve the product design to ensure the safety and reliability of stamping equipment.

2 Install protective devices. Due to the small production batch, safety protection devices must be installed in stamping operations that can neither be automated nor use safety stamping tools to prevent injury accidents caused by operational errors. All kinds of protective devices have different characteristics and application scope, and improper use will still cause injury accidents. Therefore, it is necessary to know the functions of various protective devices in order to use them correctly and ensure the safety of operation.

3. Reform the process, mold and operation mode to realize off-mold operation. For mass production, we can start with the reform of technology and mold to realize mechanization and automation. For example, combined process measures such as automation, multi-station stamping machinery and equipment, multi-tool marking and mechanized feeding and production equipment, continuous die and compound die are adopted. These not only ensure the safety of stamping operation, but also greatly improve the production efficiency.
