Share the precision metal stamping parts trimming punch design standard
Precision metal stamping mold punch in the case of no other customer standards, we in order to reduce the material and processing cost, increase the intensity of the punch, punch the fixed, can be made in the form of two planting: 1.
Small can't lock screw, precision metal stamping parts punch punch made during open thick soft material allowance, blade edge CNC jing gong to number after quenching, screw verification steps do fixed hole;
Precision metal stamping punch can directly meet the lock screw and taper pin, made punch punch sitting on a soft seat material, the shortest part of the punch under the condition of not less than 30 mm punch the total height of try to be the shortest;
In the case of to ensure the strength of stripper seat can prevent the punch shape gong steps do short punch.
It is worth noting: the punch in the fixed form Ⅰ R in does not affect the structure of the case as far as possible big, in the small gong R reduction of processing difficulty and eliminate the stress concentration when heat treatment.
