1. Stamping manufacturing efficiency is high; practical operation is convenient; mechanical automation and automation technology are convenient. This is because stamping is completed through stamping dies and stamping equipment. The stroke of ordinary press can reach dozens of times per minute, and the high-speed press can reach hundreds or even thousands of times per minute. Stamping parts can be obtained for each stamping stroke.
2. During stamping, because the die ensures the size and shape accuracy of the stamping parts, the surface quality of the stamping parts is not easy to be damaged. The service life of the die is generally long, the stamping quality is stable, and the exchangeability is good.
3. Stamping can produce parts with large specifications and complex shapes, such as watch timers, automotive side beams. In addition, the cold deformation hardening compressive strength of raw materials under stamping condition is relatively high.
4. Stamping generally does not produce debris. With less material consumption and no need for other heating equipment, it is an energy-saving material, energy-saving processing method. The cost of stamping parts is very low.
Common problems of precision stamping processing
Common problems in metal stamping processing include: deformation and burr of precision stamping parts; warpage, surface scratch, angular deformation, etc; the flange of the drawing part is wrinkled, the drawing wall is wrinkled, the drawing wall is damaged, cracked, etc., and the expansion shape is uneven.
Solutions to common problems: die design should have reasonable punch and die clearance value, circle radius and processing accuracy. When designing the bending die, effective measures should be taken to reduce the rebound on the die, and reasonable rounded corners should be designed to prevent bending. When drawing, use pressure edge to prevent medium pressure. Properly lubricate to reduce drawing resistance and prevent the die from sticking or pulling the workpiece. Use professional stamping oil that meets the process requirements.
