Boluo hardware stamping parts processing, what are the common causes of stamping defects + 15 years of manufacturers show you

The hardware production staff responsible for the processing of Boluo hardware stamping parts said that stamping die is a special process equipment for processing materials into parts (or semi-finished products) in stamping processing. According to the nature of the process classification: blanking die, bending die, drawing die, forming, etc. Classification according to the degree of process combination: single process mold, compound mold, progressive mold. The three elements of stamping production: reasonable stamping technology, advanced molds, and efficient stamping equipment. The following Xiaoshuo will show you the common defects of stamping and their causes: 1. Blanking, punching, trimming defects: too large burrs, deformation, surface scratches, size inconsistencies, few holes, etc. (1) Too large burrs → convex and concave The die gap is too large or too small; the cutting edge is worn; the guiding accuracy is poor; the position of the convex and concave molds is not concentric, etc. (2) Deformation → The hole distance is too small; the pressure plate does not fit well with the concave mold surface; the gap is too large, etc. (3) Surface scratches → drag and pull during operation; the sheet material is scratched during the cutting process. (4) Size inconsistency → feeding is not in place; positioning device is damaged or loose, position shifting, etc. (5) Fewer holes → the punch is broken; the length of the punch is not enough, etc. Blanking, punching, and trimming products are prone to defect positions 2. Drawing and drawing products are prone to defect positions 3. Flanging Defects: Flanging is not vertical, flanging height is inconsistent, flanging fuzzing, flanging cracks, etc. (1) The flanging is not vertical → the gap between the convex and concave molds is too large. (2) Inconsistent flanging height → uneven gap between convex and concave molds; inaccurate positioning; inaccurate size of blanking parts. (3) Flanging and roughening→The cutting edge has scars; there are impurities on the surface of the parts; the cutting edge hardness is too low. (4) Flanging crack → large burrs when trimming; the gap between the convex and concave molds is too small; there is a sudden change in the shape of the flanging. Flanging products are prone to defects. 4. Bending Defects: unqualified bending angles, broken edges, steps at the corners of bending, etc. (1) The bending angle is unqualified → the gap between the convex and concave molds is too large, and the matching angle of the convex and concave molds does not match the thickness of the plate material. (2) The bending edge is broken → the gap between the punch and the die is too small; the bending angle is too small; the punching force is too large and the speed is too fast; the plate material is too hard. (3) The bending R angle has steps → the convex and concave die bending angle is too large; the outer R angle is too large; the bending force is too small. Bending products are prone to defect location hardware, 15 years of focus on Boluo hardware stamping parts processing, 20,000+ sets of customized stamping die production experience, monthly 100+ sets of mold processing capacity, hundreds of precision processing production equipment, daily production of 3 million punches Production capacity, silk-like stamping accuracy can reach 0.01mm, raw materials are imported and national standard original factories, and 16 quality inspections are strictly controlled. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose to rest assured!
