What are the stamping is one of the more common method

⑴。 Reasonable die design. In the progressive die, blanking order arrangement is likely to affect the precision of the stamping forming. For stamping fine blanking parts, general arrangement of large-area first cutting blanking, then arrange the punching blanking of smaller area, in order to reduce the cutting force of the influence of the stamping forming. ⑵。 Pressure material. To overcome the traditional mould design structure, open capacity on the stripper plate material clearance ( The mold closed, and material can be pressure. Key to forming part, stripper plate must be making set piece of structure, to facilitate solving caused long time stamping produced material parts on the stripper plate mill ( Pressure) Loss, and can't pressure material. ⑶。 Add crush functions. To discharge set piece of material of pressure increasing size, Normal discharge with pieces of thick H + 0. 03mm) To increase the pressure on the concave side material, thus inhibiting the punching stamping double material and torsion deformation. ⑷。 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. ⑸。 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, and stamping parts produced material, distortion tends to increase. ⑹。 Cutting clearance is not reasonable or uneven clearance is also produce stamping parts material, the reason of the distortion, need to be overcome.
