Improve the terminal stamping materials, the distortion of plan
Reasonable mold design: blanking sequence affecting the precision of the terminal stamping forming.
General arrangement of large-area first cutting blanking, arrange punching blanking, smaller area to mitigate the effects of cutting force in stamping forming.
Pin material: open capacity on the stripper plate material clearance, stamping in the stripper plate smooth movement, and material can be pressure.
Key forming parts, stripper plate must be making set piece of structure, with convenient solve the stripper plate pressure caused long time stamping parts produced by the wear and tear.
Add crush function: the size of discharge set piece of pressure of thickening, to increase the pressure on the concave side material, thus inhibiting the punching stamping double material and torsion deformation.
Punch edge end fix the bevel or arc: this is an effective way to slow down the blanking force.
Slow down the blanking force, can reduce the tensile force of the concave side material, thus suppressing stamping double material and torsion effect.
Daily mold production, should pay attention to maintenance of convex and concave die cutting edge sharpness.
When cutting blade wear, material by the tensile stress will increase, thus terminal stamping parts produced material, distortion tends to increase.
Currently our stamping speed can reach more than 1000 times per minute, the 16 cavity mould can produce 12 a day.
5 kk terminal stamping parts.
