Abstract
The utility model discloses a lower die of a forming die for gear shafts. The lower die comprises a square seat body, wherein a step-shaped cavity comprising an upper large-diameter hole and a lower small-diameter hole is formed in the seat body; a transitional hole is formed between the large-diameter hole and the small-diameter hole; and a supporting seat is arranged at the bottom end of the seat body. The lower die has the advantages that the gear shaft cavity of the lower die is adopted to blank the hot-forged gear shafts, so that the processing efficiency is further improved; and the gear shafts can be punched and processed on a large scale, and the accuracy of forms and positions of the gear shafts is improved.
Description
Technical field
The utility model relates to a kind of counterdie that is used for the mould of gear shaft.
Background technology
Blanking die is the mould that material production is separated along the outline line that seals or open wide.Like blanking die, perforating die, knife edge die, notch die, edger, parting die etc.After the present gear train process forge hot, the shape basic forming of gear shaft, but dimensional accuracy does not still reach the dimensional requirement of design, and the stamping-out that need carry out next step is shaped and handles.
The utility model content
The purpose of the utility model provides a kind of counterdie that is used for the mould of gear shaft; The gear shaft of the gear shaft die cavity that adopts counterdie after to forge hot carries out stamping-out; Working (machining) efficiency further improves, and can carry out punching processing in enormous quantities, has improved the accuracy of form and position of gear shaft.
The technical scheme of the utility model is following:
A kind of counterdie that is used for the mould of gear shaft; Include square pedestal, have step-like die cavity in the pedestal, die cavity is the small diameter bore by top large diameter hole, bottom; Be transitional pore between large diameter hole and the small diameter bore, the bottom of pedestal has supporting seat.
The upper end of described large diameter hole has chamfering.
The gear shaft of the gear shaft die cavity that the utility model adopts counterdie after to forge hot carries out stamping-out, and working (machining) efficiency further improves, and can carry out punching processing in enormous quantities, has improved the accuracy of form and position of gear shaft.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to accompanying drawing; A kind of counterdie that is used for the mould of gear shaft includes square pedestal 1, has step-like die cavity 2 in the pedestal 1; Die cavity 2 is the small diameter bore 4 by top large diameter hole 3, bottom; Be transitional pore 5 between large diameter hole and the small diameter bore, the bottom of pedestal has supporting seat 6, and the upper end of large diameter hole has chamfering 7.
Claims (2)
1. counterdie that is used for the mould of gear shaft; Include square pedestal, have step-like die cavity in the pedestal, die cavity is the small diameter bore by top large diameter hole, bottom; Be transitional pore between large diameter hole and the small diameter bore, the bottom of pedestal has supporting seat.
2. the counterdie that is used for the mould of gear shaft according to claim 1 is characterized in that: the upper end of described large diameter hole has chamfering.
