Metal stamping tensile process types respectively have?
As one of the main stamping process, metal stamping tensile, they are widely used in tensile process can be made into all kinds of cylindrical, rectangular, spherical, and other parts of irregular shape, today and share the type of processing technology have?
Metal stamping tensile circular tensile processing: flange circular tensile products, also at the bottom of the flange are planar shape, wall for axisymmetric deformation is uniformly distributed on the same circumference of a circle, flange blank drawing deformation;
Rectangular drawing processing will be a stretch forming rectangular pieces of a low, rounded corners in tensile flange deformation zones resistance is greater than the straight tensile Yin forces outside the rounded deformation degree is greater than the straight edge in the deformation degree;
Deep processing of deep drawing parts processing: more than the ultimate tensile strain of processed products, need to go through more than two times stretching can finish many times, after the former station depth direction tensile processing products, in the depth direction for stretching processing;
Reverse drawing processing: process before drawing the workpieces, reverse stretching, can increase the radial tensile stress, to prevent wrinkling can get better effect, may also improve tensile coefficient.
