We, Dongguan Bosi Hardware, have over 10 years of experience in the precision stamping industry and are almost familiar with the process flow of precision stamping for shielding covers. The shielding cover stamping parts we use precision stamping technology for have the advantages of lightweight and high precision, and are widely used in various fields. Below, Dongguan Bosi editor will introduce the precautions for stamping process of shielding cover.

What should be paid attention to in the stamping process of shielding cover

1shield canThe number of stamping processes mainly depends on the complexity of its structural shape, determined by the number of bending angles, relative positions, and bending directions. When the bending radius of the bent part is less than the allowable value, an additional shaping process is added after bending.

2. The number of processes for stamping shielding covers is related to material properties, drawing height, number of drawing steps, drawing diameter, material thickness, and other conditions, and can only be determined through drawing process calculations. When the fillet radius of the deep drawn part is small or the dimensional accuracy requirement is high, an additional shaping process needs to be added after deep drawing.

3. The determination of the number of processes should also be in line with the existing molding capacity and stamping equipment of the enterprise. The molding capability should be able to ensure the corresponding improvement of mold processing and assembly accuracy, otherwise the number of processes can only be increased.

4. When the cross-sectional quality and dimensional accuracy requirements of the stamped parts of the shielding cover are high, it is possible to consider adding a trimming process after the punching process or directly using a precision punching process.

5. In order to improve the stability of the shielding cover stamping process, it is sometimes necessary to increase the number of processes to ensureshield canThe quality of stamped parts. For example, the additional positioning process of punching holes for bent parts, the addition of deformation reduction holes in forming processes to transfer deformation zones, and so on.

6. The shield cover stamping parts with simple punching shapes are completed using a single process mold. For workpieces with complex punching shapes, due to limitations in the structure or strength of the mold, the inner and outer contours should be divided into several parts for punching, requiring multiple punching processes.

7. The use of specialized stamping oil can effectively improve process accuracy and fundamentally eliminate problems such as yellowing and skin irritation caused by non specialized oils such as rapeseed oil, mechanical oil, and recycled oil sticking to the machine.

8. Always follow safety regulations when working. Always follow the prescribed safety regulations during stamping; When working, one should wear work clothes and hats, work diligently, always adhere to their position, concentrate their thoughts, and prevent personal accidents.

9. The first piece of shielding cover must be inspected and qualified before production. During the stamping process, self inspection and special inspection should be carried out at any time, and the host should not be used for double material. Waste materials should be cleaned up in a timely manner. When a malfunction occurs, the machine should be shut down immediately, and relevant departments should be reported in a timely manner. Only after restoring normal operation can production be started.
