Abstract
The utility model discloses a piercing die for thermally calibrating speed change gears. The piercing die comprises a female die and a punch, wherein a gear cavity is formed in the upper end surface of the female die; the punch is fixed at the lower end of an upper die fixing plate; a material spilling opening corresponding to the punch is formed in the female die; material unloading rods are respectively fixedly arranged on two sides of the upper end surface of the female die; a material unloading plate is sleeved on the material unloading rods; and springs are arranged between the material unloading plate and the top ends of the material unloading rods. Through the adoption of the piercing die, hole position dimensions of the gears are further calibrated, the processing efficiency is further improved, the gears can be thermally calibrated on a large scale, and the accuracy of forms and positions of the speed change gears is improved.
Description
Technical field
The utility model relates to punching die, specifically belongs to a kind of speed change degree gear thermal recalibration punching die that is used for.
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 change-speed gearing process forge hot, the installing hole shape basic forming of gear, but dimensional accuracy does not still reach the dimensional requirement of design, and the thermal recalibration mould that need carry out next step carries out shaping to be handled.
The utility model content
The purpose of the utility model provides a kind of speed change degree gear thermal recalibration punching die that is used for, position, the hole size of further corrected gear, and working (machining) efficiency further improves, and can carry out thermal recalibration processing in enormous quantities, has improved the accuracy of form and position of change-speed gearing.
The technical scheme of the utility model is following:
A kind of speed change degree gear thermal recalibration punching die that is used for; Include former, drift, have the gear die cavity on the former upper surface, drift is fixed in the lower end of upper mould fixed plate; Have in the former and the corresponding leakage material of drift mouth; The both sides, upper surface of former are fixed with discharge arm respectively, are set with stripper on the discharge arm, are provided with spring between the top of stripper and discharge arm.
The both sides of described former are respectively equipped with breach.
The utility model is that the product gear is put in the gear die cavity, utilizes drift to press down punching then, position, the hole size of further corrected gear, and working (machining) efficiency further improves, and can carry out thermal recalibration processing in enormous quantities, has improved the accuracy of form and position of change-speed gearing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
