METHOD OF MULTIROW PROGRESSIVE LOW-WASTE FORMING

摘要

FIELD: plastic metal working, namely manufacture of hexagonal cards of strip or band materials. SUBSTANCE: method comprises steps of feeding material by angle relative to line of row of formed parts. Forming operation is realized by cutting material along broken line with toothed profile. Each tooth of profile corresponds to portion of hexagonal contour of formed part. Inclination angle of material feed is determined according to given formula. For each successive cycle direction of material feed is changed to opposite one. EFFECT: enhanced efficiency. 2 cl, 4 dwgi
