subject: Anything Deep drawn parts and about stamping parts [print this page] The reason is too many rough corners or corner materials have glitches. Solution is to reduce the materials or polish rough corner corner glitch.Department of workpiece wall flange wrinkling and rupture.Because the mold does not come out too small to plug holes or vents top feed bar and the workpiece contact surface is too small, the top feed bar is too long. Solution is to drill out the holes expanded; finishing top feeding device.
Because the rough center and punch deep drawn parts centers do not overlap or deep drawn parts uneven thickness; die radius and die gap unevenness. Solution is to adjust the location; school uniform clearance and trimming die radius.Risk profile significantly thinner.The reason is too small die radius, blank holder force too much material caused by the dangerous section of the radial tensile necking. Solution is to increase the die radius and clearance, rough coated with a suitable lubricant.Pull off the deep drawn parts bottom of the workpiece. The reason is the die radius is too small, material to be cut in the state. Solution is to increase the die radius.Workpiece edge wrinkles.
The reason is the die radius is too large stage deep drawn parts is not out of the blank holder but not the material over the die corner than blank holder pressure, wrinkle after being drawn into the die to form the edge of wrinkles . Solution is to reduce the die radius or the use of curved blank holder.Because deep drawn parts the corner gap is too small, and the surplus material to deep drawn parts the loss of stability and wrinkle wall extrusion. Solution is to enlarge the corner space, reducing the straight wall part of the gap.Conical or hemispherical pieces of pieces of wall wrinkling.Workpiece edge of the level of inconsistency.
