Description

The combination die of automobile axle clutch plate gear blank warm and hot forging

Technical field

The utility model belongs to hot forged metal field shaping technique, relates to a kind of for automobile axle clutch plate gear ring blank non-trimming warm and hot forging mould.

Background technology

At present, the production method of automobile axle driven tooth disk ring part is: with base steel for raw material, through blanking, forging base, die forging, obtain the blank with rear axle driven gear ring adjoining dimensions, then after heat treatment, finish turning processing, obtain automotive driven gear ring, in contour forging technique, need the mould using special shape to carry out die forging base; But a lot of factory now, the Design of Dies of use is unreasonable, belongs to open type forging, produce forging flash, need to increase process equipment cutting edge, the blank that die forging obtains and the External Shape that will manufacture differ greatly, when increasing the machining of rough turn, finish turning processing, waste of raw materials is very large.

Utility model content

The utility model technical issues that need to address overcome the deficiencies in the prior art, provides a kind of energy no-flash die forging mould, save forging material, improve the forge die life-span; Reduce product cost.Extensively be suitable for the capable medium-and-large-sized dish tooth class ironcasting blank of forging, rough turn processing and finish turning processing that forging blank needs to carry out large cutting output.

The utility model solves the technical scheme that its technical problem adopts:

(1), when adopting forging stock to expand rolling, control unnecessary metal can not be had to flow into the gap of mould upper and lower die joint when forging is shaping by the geometry of rolling over ring core.

(2) adopt closed forging, avoid the formation of overlap, saved forging material.

(3) lower module adopts assembling die by lower die-cushion and lower mold core.Wherein mainly solve following difficult point:

A, lower mold core are stressed large, yielding, should select the good wolfram steel mold materials of red hardness;

When B, discharging, lower module and workpiece under employing push rod immediate roof, forging depanning is fast, forging comparatively fast departs from lower mold core.Above 2 improve die life and have saved expensive mold materials.

Design of Dies embodiment: for the leading driven spiral bevel gear of 469,485 vehicle bridge of Dongfeng Auto Company;

Existing product Fig. 1 open die has overlap mould to be the usual design that current automobile industry forges vehicle bridge clutch plate gear.There is following problem in this mould:

1, for the ease of the demoulding of forging, one is that die joint is selected in Φ 290 endoporus position on the upper side, two pattern drafts being increased module and upper mold core.

2, lower module does not depart from forging in whole forging forming and ejection process, and therefore lower module heated time is long, shortens die life.

3, as shown in Figure 1, be the forging of this mould excellent suitability for press forming, this forging forges due to the overlap that has that pattern draft is large, endoporus belongs to open type, and A indication region is the die forging product for there being overlap as shown in Figure 2.

4, the portion of material that has more of forging, needs two times punch to remove and cuts off large overlap.Also retain thin-sheet, need rough turn processing.

Technical solutions of the utility model are the no-flash die forgings of design enclosed, as shown in Figure 3, are that the driven spiral bevel gear after improving becomes swage die.This mould has the following advantages:

1, endoporus and outer full be closed die forging (no-flash die forging).

2, lower module adopts assembling die by counterdie circle and lower mold core.Push rod goes out forging and has namely departed from lower mold core, shortens lower mold core high temperature time of contact, improves the service life of lower mold core.

3. this lower mold core is lighter than the lower module of Fig. 1 overlap forging die 60 kilograms, has saved expensive mold materials.

The utility model has the advantages that: hot forged mould structure described in the utility model is simple, easy to operate; It is shaping that non-trimming belongs to closed die forging.And use described assembling die, the blank with rear axle driven gear ring profile and adjoining dimensions can be forged accurately, simply and fastly, reduce difficulty that is rough turn, finish turning processing, improve production efficiency, reduce production cost.

The beneficial effects of the utility model are:

Forge hot non-trimming assembling die structure described in the utility model is simple, easy to operate; The blank of taking turns ring profile and adjoining dimensions with driven pulley fluted disc can be forged accurately, simply and fastly, reduce difficulty that is rough turn, finish turning processing, improve production efficiency, reduce production cost.

Detailed description of the invention

Referring to drawings and Examples, the utility model is described in detail:

From accompanying drawing 1 ~ 4, a kind of assembling die for clutch plate gear ring blank forging, formed primarily of upper die and lower die two parts.Wherein part of the upper die is made up of upper mold core 1, upper die-cushion 2, patrix 3 and Upper Die-sleeve 4.

Part of the lower die is made up of counterdie 5, push rod 6, lower mold core 7, lower module 8, die shoe 9, lower die-cushion 10, lower die-sleeve 11.

Described lower module 8 adopts assembling die mode to be connected by lower die-cushion 9 and lower mold core 7, and by lower die-sleeve 11 Global Macros in addition in outside.

Described lower mold core 7 is stressed large, yielding, selects the good wolfram steel mold materials of red hardness;

Described upper mold core 1 is responsible for the shaping of basin tooth edge, and lower mold core 7 is responsible for the flexible small stair hole size of basin tooth lower end Internal periphery.Lower module 8 is responsible for the size ensureing basin tooth baseplane.Lower die-cushion 10 is arranged on the outside of lower module 8, and can eject for making workpiece and adopt combination die form, the workpiece of die-forging forming can eject with push rod 6 by lower module 8, and lower module requires to adopt heat-resisting tungsten alloy steel, to improve the mold use life-span.Same counterdie outermost is lower die-sleeve 11, and its effect is that protection lower mold core 7 and lower die-cushion 10 are motionless, is combined into an entirety.

Same described part of the upper die comprises: upper mold core 1, require that material is best; the general material in upper die-cushion 2 side, patrix 3 Main Function face is also reddish tone wolfram steel material, and Upper Die-sleeve 4 size is maximum to be connected with patrix 3; using general material, is the basis of protection and fixing patrix 3.

During discharging, adopt push rod immediate roof lower module 8 and workpiece, forging depanning is fast, forging comparatively fast departs from lower mold core.Above 2 improve die life and have saved expensive mold materials.

Good economic effect is had compared with traditional design.(production capacity producing 150000 by company per year calculates)

1, the forging heavily about 1.5 kilogram of Fig. 2 forging A indication region than Fig. 4 of overlap is had.Pinion steel 40Cr material price 6 yuan/kilogram, saves 1.5 × 6 × 1,500,00=,135 ten thousand yuan every year.

2, lighter than Fig. 1 lower module 60 kilograms by Fig. 3 lower mold core.Two kinds of die lives can produce 10000 equally, mould steel H13 price 24 yuan/kilogram, add the per kilogram mould such as heat treatment expense, machined expense expense about 40 yuan.Annual saving 150000/10000 × 60 × 40=36000 unit.

3, the forging A indication region overlap of Fig. 1 need increase by a procedure, and deflashing is forged and pressed.Wash away overlap and need large tonnage equipment, cost is high.The method of less expensive is exactly lathe car overlap, the approximately every part 1 yuan of labour cost, lathe expense.Annual saving 150000 × 1,=15 ten thousand yuan.Scheme after improvement can save 153.6 ten thousand yuan every year.This die design schemes can be widely applied in auto parts and components forging manufacturing.

The above, be only the utility model embodiment, therefore the scope of the utility model enforcement can not be limited with this, namely the equivalence change done according to the restriction of the utility model claim and description and claims with modify, all should still belong in scope that the utility model patent contains.
