Common problems in processing Metal Stamping Parts include deformation and burr of precision stamping parts. Cracks, warpage, surface scratch and angular deformation of bending parts; Flange wrinkling, drawing wall wrinkling, drawing wall damage, drawing crack, etc. Flanging cracks, uneven bulging, etc. Solutions to common problems: die design should have reasonable clearance value of convex and concave dies, fillet radius, machining accuracy, etc. When designing bending dies, effective measures should be taken to reduce springback and the amount of springback should be subtracted from the dies. Reasonable rounded corners are designed to prevent bending crack. During drawing, a blank holder is used to prevent wrinkling and the pressure should be moderate. Reduce drawing resistance with proper lubrication to prevent die adhesion or workpiece drawing through; Use professional stamping oil that meets the process requirements. The above problems concerning the classification and processing of precision Bakelite Parts are summarized here. Reasonable arrangement of the process can effectively improve the processing efficiency and reduce the production cost. I hope the above sharing is helpful to everyone.
