Abstract
The utility model discloses a hot forging mould for an auto automatic transmission output spline shaft. The mould comprises an upper mould seat and a lower mould seat, an upper mould is arranged on the upper mould seat and an upper mould guide ring is arranged around the upper mould; below the upper mould, a shaping lower mould upper section and a shaping lower mould lower section are arranged correspondingly below the upper mould, the cavity of the upper mould and the cavities of the shaping lower mould upper section and the shaping lower mould lower section correspond, and a shaping cavity is formed after mould-closing; and an ejector rob is arranged below the shaping lower mould lower section, is communicated with the cavity of the shaping lower mould lower section, and can extend into the cavity of the shaping lower mould lower section. The hot forging mould combines cold forging and hot forging, and can produce the auto automatic transmission output spline shaft only through adopting the forging method, the shaping precision is high and the cost for parts is low; the material utilization rate is high and can reach higher than 95%; and the production efficiency for parts can be considerably improved to meet market demands.
Description
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 hot forged mould.
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 forge hot is provided; It combines through hot and cold forging, adopts the method for forging to make the hot forged mould of automatic gearbox output spline.
The technical scheme of the utility model: automatic gearbox output spline hot forged mould, comprise upper bolster and die shoe, it is characterized in that: upper bolster is provided with patrix, and the patrix guide collar is set around patrix; Below patrix, correspondence is provided with moulding counterdie epimere and moulding counterdie hypomere, and patrix, moulding counterdie epimere are corresponding with the die cavity of moulding counterdie hypomere, forms the moulding die cavity behind the matched moulds; Below moulding counterdie hypomere, be provided with push rod, push rod is communicated with the die cavity of moulding counterdie hypomere, can stretch in the die cavity of moulding counterdie hypomere.
Further characteristic is: said moulding counterdie epimere and moulding counterdie hypomere are through guide collar, lower bolster are connected on the die shoe down.
Upper die plate is set on upper bolster, patrix be arranged on upper die plate below.
The utility model automatic gearbox output spline finish forge base hot forged mould 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 hot-forging forming mould scheme of erection.
Fig. 2 is the utility model splined shaft forge hot base figure.
The specific embodiment
In Fig. 1,2; The utility model automatic gearbox output spline hot forged mould comprises upper bolster 1 and die shoe 2, and upper bolster 1 is provided with patrix 3; Concrete structure among the figure is that upper die plate 4 is set on upper bolster 1; Patrix 3 be arranged on upper die plate 4 below, (both sides) are provided with patrix guide collar 5 around patrix 3, make things convenient for patrix 3 under actuating unit drives, to move up and down; During the forging and pressing operation, patrix 3 is given the blank active force as forging hammer.
Below patrix 3; Correspondence is provided with moulding counterdie epimere 6 and moulding counterdie hypomere 7; Patrix 3, moulding counterdie epimere 6 are corresponding with the die cavity of moulding counterdie hypomere 7; Make according to technological requirement, form moulding die cavity 8, the utility model automatic gearbox output spline hot-forging forming in moulding die cavity 8 behind the matched moulds.Said moulding counterdie epimere 6 all is arranged on the die shoe 2 with moulding counterdie hypomere 7, and the concrete structure among the figure is through guide collar 9, lower bolster 10 are connected on the die shoe 2 down; Below moulding counterdie hypomere 7, be provided with push rod 11; Push rod 11 is communicated with the die cavity of moulding counterdie hypomere 7; Can stretch in the die cavity of moulding counterdie hypomere 7, when the demoulding, drive down from following to active force of forging (output spline), forging is ejected in moulding die cavity 8 at power set.
During work; At first suitable blank is inserted in the moulding die cavity 8, the forcing press of adapted drives cope match-plate pattern 1 and moves down, and cope match-plate pattern 1 drives patrix 3 and moves down; Patrix 3 is in the decline process; Give the blank active force as forging hammer, make blank forging forming in moulding die cavity 8, the shape that acquisition needs.After forging and pressing finished, liftout attachment drove push rod 11 and moves upward, and push rod 11 ejects forging in moulding die cavity 8.
