Abstract
The utility model discloses a hot-forging mould for the driving disc hub of an automotive transmission, comprising an upper die plate and a lower die plate, wherein a guide pole is used for guiding when the upper die plate and the lower die plate are closed; the hot-forging mould for the driving disc hub of an automotive transmission is characterized in that: an upper die seat is disposed on the upper die plate, and a forming upper die and a forming upper die core are disposed on the upper die seat; a lower die seat is disposed on the lower die plate, and a forming lower die is disposed on the lower die seat; the die cavities of the forming lower die and the forming upper die are corresponding, and a hot-forging die cavity is formed after closing; and a mandril is disposed on the lower die seat and communicated with the forming lower die. The hot-forging mould disclosed by the utility model can obtain a tooth-shaped blank while hot-forging, and the hot-forging mould is a key device for producing the product by forging; the matched device is a universal press machine, which is less in investment and convenient to operate; the mould structure composes one set by different procedures; upsetting (blanking), hot-forging, hot-sizing and hot-trimming are finished in respective moulds, so that the moulds are convenient to manufacture and low in cost; the hot-sizing is performed by the waste heat of the blank after the hot-forging, which is good for increasing the life of the mould.
Description
Technical field
The utility model relates to the making mould of the driving-disc hub forging of using in the vehicle transmission field, especially automotive transmission driving-disc hub hot forged mould.
Technical background
Automotive transmission driving-disc hub be the automobile transferring power must appliance, be an important power transmission member, it passes to power transmission shaft with output speed in the speed changer and power (moment of torsion) through the dish hub, makes automobile that enough power sources arranged and steadily moves ahead.The structure of this driving-disc hub is like Fig. 1, shown in 2; A plurality of driving cogs are arranged on its external peripheral surface; But this driving cog has certain back taper angle (the A place among the figure), is difficult to withdrawing pattern when causing forging, and adopts conventional stripping means or structure can't realize its suitability for industrialized production; In addition; A plurality of driving cogs are arranged on external peripheral surface, all are to adopt the mill teeth machine, sew with long stitches gear form processing device such as tooth machine and process profile of tooth, and efficient is low; Stock utilization is low; Cause its processing cost higher always, and its machining accuracy difficulty satisfy powerdriven needs, quality stability is relatively poor between the product of different batches.
Summary of the invention
The utility model adopts gear form processing device to process profile of tooth to the driving cog on the automotive transmission driving-disc hub external peripheral surface in the prior art; Deficiencies such as the efficient that exists is low, stock utilization is low, processing cost is higher, machining accuracy is lower, the automotive transmission driving-disc hub hot forged mould that provides a kind of forging and pressing mode cheaply to produce.
The technical scheme of the utility model: automotive transmission driving-disc hub hot forged mould, comprise cope match-plate pattern and lower bolster, adopt the guide pillar guiding when cope match-plate pattern and lower bolster matched moulds; It is characterized in that: cope match-plate pattern is provided with upper bolster; Upper bolster is provided with moulding patrix and moulding upper mold core, and lower bolster is provided with die shoe, and die shoe is provided with the moulding counterdie; The moulding counterdie is corresponding with the die cavity of moulding patrix, forms the forge hot die cavity behind the matched moulds; Die shoe is provided with push rod and is communicated with the moulding counterdie.
Further characteristic is: below push rod, the secondary push rod is set, the secondary push rod passes the following end in contact of lower bolster and push rod, and the secondary push rod can drive push rod and move upward.
Between moulding patrix and upper bolster, be provided with guide collar; Between moulding patrix and cope match-plate pattern, be provided with some interconnective upper padding plates.
Between moulding counterdie and die shoe, be provided with retainer plate; Between moulding counterdie and lower bolster, be provided with some interconnective lower bolsters.
The automotive transmission driving-disc hub hot forged mould of the utility model has following characteristics:
1, can when forge hot, obtain having the blank of profile of tooth, this hot forged mould is to adopt forging and pressing to produce the key equipment of this product; The equipment of adapted is universal forcing press, small investment, convenience;
2, the mould structure operation break-down has a cover of one's own, and pier thick (base), forge hot, hot school shape, hot trimming are all accomplished in the mould separately, are convenient to manufacturing and with low cost;
3, utilize the blank waste heat to carry out hot school shape after the forge hot, help promoting die life.
