20 things that cannot be done in the stamping and bending process of die design
The quality of metal stamping parts is closely related to the stamping die, and the design of the stamping die must be reasonable to avoid a series of subsequent problems due to design defects. The following are 20 things that we cannot do in the stamping and bending process of die design based on practical production activities and the experience of others. Let’s learn together. 1. The bending fillet radius should not be too small. 2. The bending fillet radius should not be too large. 3. The bending edge distance should not be too small. 4. The bending straight edge should not be too small. 5. The bending radius should not be too small. With ordinary bending method 6, springback cannot be ignored in bending process 7, process cut 8 should not be ignored in narrow side bending, punching and unloading holes should not be ignored in partial bending edge, and the symmetry of bending shape and size should not be too different 10 , Bending parts should not have gaps at the edges 11, ordinary bending methods should not be used for bending of pipes and profiles 12, materials with high yield points should not be used for bending workpieces 13, materials with small elastic modulus should not be used for bending workpieces 14, for bending radii and radian angles Common bending methods should not be used for the large bending parts. The mold structure should not hinder and prevent the rotation and movement of the blank during the mold clamping process. The bending mold structure should not cause the material to cause large local thinning and Scratch 17, the structure of the bending die cannot ignore the offset of the blank 18, the bending of the complicated shape parts cannot be in place at one time19, the general rolling forming method is not suitable for the parts with variable cross-sections20, and the ordinary bending method is not suitable for the bending of long strips [Related Recommended] Learn more: The difficult problem of precision stamping die design and manufacture.
