METHOD OF UPSETTING FRAGILE AND LOW-PLASTICITY CYLINDRICAL BLANKS |
摘要 |
FIELD: process engineering.SUBSTANCE: invention relates to metal forming, particularly, to upsetting of cylindrical blanks from fragile and low-plastics. Yoke is arranged at extractor surface in female die opening with clearance of 0.1-0.2 mm. Said yoke can be a split design. Blank is fitted into said yoke to strain the blank by acting with male die to yoke with blank. Male die has bottom straining part, its diameter exceeding maximum diameter of the blank after upsetting at preset reduction by 5-10 mm.EFFECT: higher compressive loads and strain at room temperature and lower temperatures in one shaping pass.2 cl, 2 dwg |
