Warpage deformation of blanking parts

1) The reason for the warpage and deformation of the blanking part: the blanking part has a gap force and a reaction force, which does not produce a moment in a line. When the gap between the convex and concave molds is too large and the cutting edge of the concave mold has a reverse taper, or the contact area between the ejector and the workpiece is too small, warping will occur. 2) Countermeasures for warping deformation of blanking parts: The blanking gap should be selected reasonably; a blanking plate or a holding plate should be added to the mold structure, and the plate and the blanking plate should be in contact with a certain pressure; check the die edge If back taper is found, the cutting edge of the die must be trimmed appropriately; if the shape of the blanking part is complicated and the inner hole is large, the uneven shear force increases the pressing force, and the strip is compressed before punching or high-precision Press punching; Regularly remove the stolen goods in the mold cavity, lubricate the surface of the thin sheet material, and have oil and gas holes in the mold structure. The precision design team has the ability to manufacture first-class high-speed stamping dies, with an average monthly development capacity of more than 20 sets of molds, and the fastest time to complete a set of molds is 14 days. It can mass produce blanking parts such as connector terminals, relay terminals, and automobile terminals. Precise contact information: Precise wishes everyone a prosperous business and all the best.
