Source: | Author:hongyuanjinshu | Published time: 2018-10-24 | 1114 Views | Share:
Mould grinds plane degree insufficient, produces the deflection deformation

Design process: the mold strength is not enough, the blade spacing is too close, the mold structure is not reasonable, the number of template blocks is not enough without pad pad

Improper wire cutting: wire drawing, incorrect clearance, no clear Angle

Selection of punch equipment: punch tonnage, blanking force is not enough, too deep under the mold

Unsatisfactory stripping: no demagnetization treatment and no stripping tip before production; Production of broken needle broken spring card material

Unsatisfactory blanking: no leakage of feces when assembling the mold, or rolling block feces, pad foot block feces

Production awareness: laminated stamping, positioning is not in place, no use of air gun, template cracks still continue to produce
