The determination of metal stamping parts and reasonable clearance

Before we talk about the effects of metal stamping parts clearance on product, understand the importance of mold clearance of stamping parts production, today we talk about how to determine the metal stamping parts reasonable clearance; We understand to the proper selection of clearance will bring metal stamping parts and other products a good cross section quality, higher dimensional accuracy, using the blanking force will also reduce, at the same time can improve the service life of the mold; Clearance is biggest, the smallest reasonable to determine the reasonable gap value, need to consider various factors, the ceiling is the biggest reasonable clearance, reasonable lower limit is the minimum clearance, the so-called reasonable interval is a range of values, in the design of hardware and stamping mould, according to the specific requirements of the production of stamping parts and can be set according to the following principles: 1. When the section of metal stamping parts without special strict requirements, in order to improve the service life of stamping mould and reduce the die cutting force, can choose the upper limit of clearance; 2. When the section of metal stamping parts quality and production tolerance accuracy is higher, we can choose the minimum clearance value; 3. We calculate metal stamping die cutting edge dimension, considering the abrasion of mold in the process of use, can make the mould clearance greatens, should be in accordance with the calculated values Zmin. More than little author accumulated in the process of production experience, for sharing. 【 Relevant recommendation 】 Details: how much do you know the new energy automotive stamping parts?
