Design points of progressive die for precision stamping parts

Design points of progressive die for precision stamping parts
1. Die fillet radius of progressive die for precision stamping parts
The fillet radius of the concave die of the precision stamping progressive die should be straight in all directions. Otherwise, when bending, the blank will slide and the product will be shifted, which will affect the accuracy and size. When designing the progressive die, the radius of the bending fillet should be selected appropriately, not too large or too small, if it is round The size of the corner radius, in order to cause local deformation or thinning of the product, and affect the quality and surface roughness of the product.

2. To prevent the deviation of the blank during the bending process
When designing a precision stamping die, in order to prevent the deviation of the blank during the bending process, the following precautions should be taken: the die should be equipped with an elastic pressing device, remember that the part of the leather should be in an elastic compression state before bending, and then Perform bending.

3. To prevent deformation during bending
When designing the multi-angle progressive die for precision stamping parts, strive to ensure that the multi-angle and multi-angle bending are not performed at the same time. When the bottom dead center of the die is bent, it should be designed to have the effect of correcting the bending. The structure design of the die should fully consider the phenomenon of springback. . When designing the positioning device, the necessary measures should be taken as far as possible to make the workpiece hold the blank as much as possible during the bending process.
