Abstract

The utility model discloses a cold-extrusion die for an output spline shaft of an automobile automatic transmission. The cold-extrusion die comprises an upper die holder, a lower die holder, an upper die cover on the upper die holder, an upper die core in the upper die cover, and an upper die fixing ring on the periphery of the upper die cover, and an upper combined female die, a central combined female die, a lower combined female die sequentially arranged under the upper die cover. After the die is closed, the molding cavities or molding surfaces of the upper die cover, the upper die core, the upper combined female die, the central combined female die and the lower combined female die form a forming cavity. A demoulding push rod, arranged under the lower combined female die, communicates with the molding cavity of the lower combined female die and be inserted into the molding cavity. The cold-extrusion die combines cold forging and hot forging means. A forging means can ensure high moulding precision of output spline shafts of an automobile automatic transmission, lower parts cost, and maintain a high utilization rate which is over 95%. Moreover, the cold-extrusion die greatly improves part production efficiency and meets market requirements.

Description

Automatic gearbox output spline cold extrusion die
Technical field
The utility model relates to a kind of mould of cold and hot forging and molding of automatic gearbox output shaft, especially automatic gearbox output spline finish forge base cold extrusion die.
Background technology
The automatic gearbox output spline is the driving parts of automobile power output, and is extremely important to vehicle safety travel.Its quality directly influences continuity, stability, the intensity quality decision driving safety of automobile power output.This part traditional processing method is that six sides and an axle upper spline tooth carry out machine and add and make that difficulty of processing is big, speed slow, destroy part fiber orientation in the termination, influences intensity; In addition, have also that material use is low, integrated cost is high, do not have deficiencies such as the market competitiveness.
Summary of the invention
The above-mentioned deficiency that the utility model exists to processing automobile automatic transmission output spline in the prior art; A kind of mould of cold extrusion processing profile of tooth is provided; It combines through hot and cold forging, adopts the method for forging to make the cold extrusion die of automatic gearbox output spline.
The technical scheme of the utility model: automatic gearbox output spline cold extrusion die comprises
Upper bolster and die shoe is characterized in that: upper bolster is provided with Upper Die-sleeve, is provided with upper mold core in the Upper Die-sleeve, and the patrix retainer plate is set around Upper Die-sleeve; Below Upper Die-sleeve, correspondence sets gradually die in combination upper cavity die, the combination, combination lower cavity die, and behind the matched moulds, the die cavity or the forming surface of die, combination lower cavity die form the moulding die cavity in Upper Die-sleeve, upper mold core, combination upper cavity die, the combination; Below the combination lower cavity die, demoulding push rod is set, demoulding push rod is communicated with the die cavity of combination lower cavity die, can stretch in this die cavity.
Further characteristic is: the combination upper cavity die is arranged in the combination fovea superior die sleeve, and die is arranged in the combination in the die case in the combination.
Combination is provided with lower bolster below the lower cavity die, lower bolster is set below the lower bolster, and described die shoe is arranged on the lower bolster.
Trim ring on below upper bolster, being provided with is provided with lower clamping ring on the cold extrusion die shoe.
The utility model automatic gearbox output spline finish forge base cold extrusion die with respect to prior art, has following characteristics:
1, the mode that combines through cold forging, forge hot just can be made the automatic gearbox output spline through the method for forging, and formed precision is high, reduces the cost of part;
2, stock utilization is high, can reach more than 95%;
3, increase substantially the production efficiency of part, satisfy the needs in market.
Description of drawings
Fig. 1 is the utility model splined shaft cold extrusion molding mould scheme of erection.
Fig. 2-1,2-2 are the utility model splined shaft cold extrusion blank figure.
The specific embodiment
In Fig. 1,2; The utility model automatic gearbox output spline cold extrusion die; Comprise upper bolster 1 and die shoe 2, upper bolster 1 is provided with Upper Die-sleeve 3, is provided with upper mold core 4 in the Upper Die-sleeve 3; Concrete structure among the figure is that upper die plate 5 is set on upper bolster 1, and Upper Die-sleeve 3 is arranged on below the upper die plate 5; Around Upper Die-sleeve 3, patrix retainer plate 6 is set, makes things convenient for Upper Die-sleeve 3 under actuating unit drives, to move up and down; During the forging and pressing operation, Upper Die-sleeve 3 moves up and down with upper mold core 4 synchronously, gives the blank active force as forging hammer.
Below Upper Die-sleeve 3; Correspondence sets gradually die 8 in combination upper cavity die 7, the combination, combination lower cavity die 9; Behind the matched moulds; The die cavity or the forming surface of die 8, combination lower cavity die 9 form moulding die cavity 10 in Upper Die-sleeve 3, upper mold core 4, combination upper cavity die 7, the combination, and blank is extruded moulding in moulding die cavity 10.Combination upper cavity die 7 is arranged in the combination fovea superior die sleeve 11, and die 8 is arranged in the combination in the die case 12 in the combination; Below combination lower cavity die 9, demoulding push rod 13 is set; Demoulding push rod 13 is communicated with the die cavity of combination lower cavity die 9; Can stretch in this die cavity, when the demoulding, drive down from following to active force of forging (output spline), forging is ejected in cold extrusion die cavity 10 at power set.Combination is provided with lower bolster 14 below the lower cavity die 9, lower bolster 15 is set below the lower bolster 14, and described die shoe 2 is arranged on the lower bolster 15.
Below upper bolster 1, being provided with trim ring 16, on cold extrusion die shoe 2, being provided with lower clamping ring 17, is detachable connection.
During work; At first suitable blank is inserted in the cold extrusion die cavity 10, the forcing press of adapted drives cold extrusion upper bolster 1 and moves down, and cold extrusion upper bolster 1 drives Upper Die-sleeve 3, upper mold core 4 moves down; Upper Die-sleeve 3, upper mold core 4 are in the decline process; Give the blank active force as forging hammer, make blank forging forming in cold extrusion die cavity 10, the shape that acquisition needs.After forging and pressing finished, liftout attachment drove demoulding push rod 13 and moves upward, and demoulding push rod 13 ejects forging and the demoulding in cold extrusion die cavity 10.
