How do stamping parts manufacturers solve the burr problem in the process-hardware

Burr refers to the irregular protrusion on the end of the punching surface of the stamping part. Its size is related to the type of material, the gap, the condition of the die edge, the depth of the punch into the die, and the number of punching times. Therefore, in the production process, stamping parts manufacturers must solve the problem of burrs in the mold design and production process. The burrs generated during punching are not cutting burrs but extrusion burrs. To determine the size of the burr, not only the height of the burr, but also the thickness of the root of the burr. According to the VDI3345 standard, when the die edge is sharp, only thin burrs are produced, eu003d0.01～0.08mm; when the die edge becomes dull, thick burrs are produced, eu003d0.1～0.3mm because stamping is a flow-shearing process When punching, the punching punch first causes the crystals of the metal structure to be strongly deformed, and then separated. Certain stamping materials affect the surface quality, dimensional accuracy and die life of stamping parts. It is the responsibility of the stamping parts manufacturer to meet the needs of customers and produce exquisite stamping parts. For hardware, the result of customer demand is the result of work. Choose, choose rest assured!
