Abstract
The utility model discloses a female die for a variable-speed gear thermal calibration punching die. The female die comprises a square block with a leak in the middle, a gear cavity is arranged outside the leak, the outer side of the gear cavity is connected with a communication notch, and two side walls of the block are provided with notches respectively. Hole position dimension of a gear is further calibrated, machining efficiency is further improved, large-scale thermal calibration is realized, and accuracy of form and position of the variable-speed gear is improved.
Description
Technical field
The utility model relates to punching die, specifically belongs to a kind of former that is used for speed change degree gear thermal recalibration punching die.
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 former that is used for speed change degree gear thermal recalibration punching die, 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 former that is used for speed change degree gear thermal recalibration punching die comprises square block, and the block middle part has Lou material mouth, and leaking a material mouthful outside is the gear die cavity, is connected with the connection breach outside the gear die cavity, opens on the two side of block and has breach.
Have the discharge arm installing hole on the upper surface of described block.
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.
The specific embodiment
Referring to accompanying drawing; A kind of former that is used for speed change degree gear thermal recalibration punching die comprises square block 1, and block 1 middle part has Lou material mouth 2; Leaking material mouthful 2 outsides is gear die cavity 3; Gear die cavity 3 outsides are connected with and are communicated with breach 4, open on the two side of block 1 and have breach 5, have discharge arm installing hole 6 on the upper surface of block.
Claims (2)
1. former that is used for speed change degree gear thermal recalibration punching die; Comprise square block, it is characterized in that: the block middle part has Lou material mouth, and leaking a material mouthful outside is the gear die cavity; The gear die cavity outside is connected with the connection breach, opens on the two side of block and has breach.
2. the former that is used for speed change degree gear thermal recalibration punching die according to claim 1 is characterized in that: have the discharge arm installing hole on the upper surface of described block.
