High speed precision stamping progressive dies not? I will tell you

by:Fortuna     2021-01-30
As metal stamping industry more and more mature, all kinds of products as long as it is first batch larger will consider adopting continuous mold production, for small and precision stamping parts, we usually design series high speed precision stamping die production, efficiency and quality can be guaranteed, the friend for just entering the line not? I'd like to introduce some. High speed precision stamping progressive dies punch blanking blanking force calculation: 1 and understand the types of the stamping processing equipment used also for die design of parts; 2, precision stamping die design of the punch, concave die technique parameter design accuracy; 3. The blanking force = cutting contour length ( If it is round = 3. 14 x diameter) X x material thickness material shear strength ( Shear strength = 0. 8 x materials tensile strength) , can be roughly calculated ( The tensile strength of sheet material that has embodied) ; High speed precision stamping progressive dies minimum blanking diameter calculation: mold in the smallest circle Kong Chong the thickness of the needle diameter or the most vulnerable place, can advance after accounting countermeasures; High speed precision stamping die continuously reduce the cutting force of methods: to adopt the method of shear Angle, blanking, take on the die shear Angle, punching, take on the punch shear Angle, if it is a thick plate, with the bevel of the shear Angle off for thickness, can reduce about 30% of the blanking force.

Details: sharing details of stamping processing industry: precision metal stamping parts figure how to draw, please be aware that this several steps
