[CN 201721588589.7] forging die clamping structure of upsetting machine
[CN 201721588589.7] Upsetting machine forging die clamping structure title: Upsetting machine forging die clamping structure application number: CN 201721588589.7 applicant: Zhangjiakou north crossing drilling tool manufacturing co., ltd. application date: 2017-11-24 patent type: utility model the utility model relates to an upsetting machine forging die clamping structure, which includes a taper sleeve and a clamping block, the clamping block is composed of a plurality of fan-shaped blocks in a conical shape, the middle of the outer surface of each of the sector blocks is provided with an inverted "T"-shaped groove, and the inner wall of the taper sleeve is provided with a "T"-shaped guide rail which is consistent with the number of the sector blocks and matches the inverted "T"-shaped groove. The utility model adopts a "T"-shaped groove rail structure for the taper sleeve and the clamping block, and uses the axial movement of the taper sleeve to realize the radial movement of the clamping block, thereby achieving the clamping and loosening of the clamping block. This structure can be directly inserted and installed when replacing the clamping block, which solves the problem of using special tools to overcome the internal elastic force in the prior art, which not only reduces the difficulty of operation, the replacement efficiency is also improved.
