Electric car stamping how to solve the problem of automobile stamping punch size not qualified
In the production of electric cars, stamping parts, will encounter 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 electric cars, 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 electric cars, 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 electric cars, 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.
