Cause analysis and treatment methods of burrs in the punching process of a stamping factory-hardware

The phenomenon of burrs during the production process of stamping dies is a common problem in stamping processing plants. If this problem is not solved, it will not only affect the appearance of the product, but also cause assembly difficulties, and even affect the customer's product itself. So how did the burr problem arise and how should it be solved? Xiaoshuo will take you to analyze: Cause analysis: 1>. The punch and the die are severely worn and the normal wear is 2>. The punch and the die are shoveled, including the material punched twice or foreign objects in the cavity, etc. 3>. The punch and the die Excessive die gap 4>. The gap between the punch and the die is offset. 5>. The cause analysis of the die blockage and cracking: 1>. The automatic feeding of the composite mold is offset or not in place, which leads to the cutting of the single side and the concave and convex die blade. Shoveling 2>. The inner and outer guide posts are offset from the positioning pin of the male and female molds, resulting in uneven clearance. 3> The end faces of the inner and outer guide posts and the male die (punch) have no shoulders, and the outer side of the female die is worn out, The punch is squeezed and moved out to produce raw edge hardware. 15 years of ingenuity and focus on stamping processing plants, more than 20 R u0026 D design engineers, product accuracy can reach 0.01MM.
