Abstract
An end flange yoke preforging die for driving shafts comprises an upper die block and a lower die block which are enclosed to form a die cavity. Two ejector rod holes communicated with the die cavity are reserved in the lower die block, and on a parting surface between the upper die block and the lower die block, the radius of a chamfer of the upper die block ranges from 5mm to 15mm, and the radius of a chamfer of the lower die block ranges from 5mm to 15mm. The chamfers of a yoke lug on the parting surface are enlarged, thus, metal flow resistance is reduced in the process of forming of forged pieces, unwanted metal on the preforged pieces is easy to be extruded to a burr bin, and folding of end toothed flange yokes is avoided. Further, the service life of the die is prolonged, forging difficulty of the like forged pieces is lowered, and yield of the forged end toothed flange yokes of the driving shafts is increased and the service lives thereof are prolonged.
Description
Technical field
The utility model belongs to the auto industry technical field, relates in particular to a kind of transmission shaft end surface flange york Preform Die.
Background technology
At present, truck drive shaft parts end surface teeth flange fork Preform Die version as shown in Figure 1, comprise upper module 1, lower module 2 and the mold cavity 3 that is encircled into by upper module 1 and lower module 2, be provided with two jogger holes 4 that are used for ejecting flange yoke forged piece in lower module 2, die joint place between upper module 1 and lower module 2 (A place), the chamfer radius R of upper module 1
1Be 3mm, the chamfer radius R of lower module 2
2Be also 3mm, because chamfer radius is less, easily cause folding in die joint place finish forging process of flange yoke forged piece fork ear, therefore guarantee finished product forging qualified repeatedly will repair a die after this Preform Die is installed on equipment, the labour intensity that has so not only increased producers has also reduced production efficiency, and easily cause mould wearing and tearing early, shortened the mold use life-span.
The utility model content
The utility model provides a kind of transmission shaft end surface flange york Preform Die that can reduce labour intensity, enhance productivity, increase the service life in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: transmission shaft end surface flange york Preform Die, comprise upper module and lower module, upper module and lower module are encircled into mold cavity, be provided with two jogger holes that are communicated with mold cavity respectively in lower module, die joint place between upper module and lower module, the chamfer radius of upper module is respectively 5mm～15mm, and the chamfer radius of lower module is 5mm～15mm.
The chamfer radius of described upper module and lower module is 10mm.
Adopt technique scheme, based on drive shaft end surface teeth flange fork finish-forging spare fork ear folding actual conditions in die joint place finish forging process, the utility model strengthens the fork ear in the chamfering at die joint place, the metal flow resistance reduces in finish-forging spare forming process like this, after blocker forging on forging unnecessary metal be easy to be pressed against the burr storehouses, avoided the folding situation in end surface teeth flange fork ear place, and improved die life, reduce the forging difficulty of this forging, improved yield rate and the service life of drive shaft end surface teeth flange fork forging.
Description of drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 2, transmission shaft end surface flange york Preform Die of the present utility model, comprise upper module 1 and lower module 2, upper module 1 and lower module 2 are encircled into mold cavity 3, be provided with two jogger holes 4 that are communicated with mold cavity 3 respectively in lower module 2, die joint place between upper module 1 and lower module 2 (A place), the chamfer radius R of upper module 1
1Be respectively 5mm～15mm, preferred 10mm; The chamfer radius R of lower module 2
2Be 5mm～15mm, preferred 10mm.
The utility model is compared with existing end surface teeth flange fork Preform Die structure, the utlity model has following advantage:
1, saving cost aspect: before architecture advances, product is 4.5% because of the folding percent defective that produces in fork ear place of flange york, improvement is by test, the percent defective of product is reduced to 1.1%, same by average forging 8.6Kg calculating, product is by 300,000 of every annual consumptions, and steel per ton are by 3800 yuan/tons, and raw material can be saved ten thousand yuan/year of 300,000 * 3.4% * 8.6 * 0.001 * 3800=33.3.
2, forging die life-span raising aspect: traditional forging mold life-span as shown in Figure 1 is 3500-4000 spare/cover die, through test, the forging mold life-span after improving as Fig. 2 is 4200-4500 spare/cover die, the cost of every cover forging die is 2.3 ten thousand/cover, 0.7 yuan of single-piece mould for forging cost, year is saved die cost: 210,000 yuan of left and right, reduced production cost.
3, by on can learn: end surface teeth flange fork of every production reduces costs 1.81 yuan with respect to before improving.
4, reduced workman's labour intensity, at forging industry, the installation of forging mold is an extremely complicated heavy muscular labor, in production in the past, error correction has repeatedly brought a lot of inconvenience to the workman, has also seriously influenced manufacturing schedule simultaneously, application of the present utility model has solved an above difficult problem.
5, be the housekeeping of later FMT knowwhy, foundation is provided.
Claims (2)
