How to solve the problem of metal stamping parts punching size does not conform to requirements

May encounter in the production of metal stamping parts, punching size small or large, and the punch size is large, in order to solve such problem, we thought in addition to forming the planning of the convex and concave die size, machining accuracy and the composition such as blanking clearance, but also from the following several aspects to think. 1, in the production of metal stamping parts, salt pieces caused by burrs generated in blanking, punching parts, need to study and pay attention to check whether the blanking clearance is reasonable. Bending instability caused by stamping, mainly for U and V bending, to bend before the stamping guide, the guide, in the process of bending and bending process of medium pressure live material prevent slippage during bending on pressing is the key to solve the problem. 2, in the production of metal stamping parts, materials tensile stress increases, stamping parts produced material, distortion tends to increase. Produce double way, punching size will be small. Crush of material, make the material produces plastic deformation, can lead to punching size is big. And reduce pressure, punching size will be small. 3, in the production of metal stamping parts, such as end slope or curved, blanking force, because salt pieces easily occurs, slander, therefore, punching size is big. And punch end plane, punching size is relatively small. Dongguan co. , LTD. , founded in 2004, is located in dongguan city, the provincial economic development zone, plant a total area of 15000 square meters, existing staff of 60 people, engineer number 15 people. The company mainly produces all kinds of stamping parts, stretching pieces, metal assembly parts and other metal mechanical parts. Company mainly on technical strength, in the production of precision machinery parts, household appliances parts, auto parts and other industries in the success of the production and management experience, the company has passed ISO9001:2015 quality system certification. 【 Relevant recommendation 】 Details: metal stamping parts in the process of design should pay attention to the details of what? Details: automotive stamping parts debugging and mid-cooling die what are the requirements? Details: metal stamping parts processing should follow the principle of what?
