Abstract
The utility model relates to that a kind of inner race is counter forces down mould, and comprise counterdie and pressure block one, pressure block one is positioned at the below of counterdie, and the arranged on left and right sides of pressure block one is respectively equipped with stripping attachment and pressure block two, and wherein the top of stripping attachment is provided with upper punch.The utility model not only further increases prestressing force, decrease anti-risk of squeezing mould radial direction cracking, improve the life-span of mould greatly, and consumptive material is few, cost is low, simultaneously Optimizing die structure, stress raiser on mould is removed, this part is transferred on upper punch, both decreased the use to more valuable mold materials, by improve the life-span.
Description
Technical field
The utility model relates to that a kind of inner race is counter forces down mould, belongs to precision metal technical field of forging.
Background technology
Inner race is one of the strength member in car drivetrain system, and its mechanical performance and contour structures require very strict, and manufacture difficulty is very large.Due to the performance of its uniqueness of Starlike Inner Race Produced by Cold Closed Die Forging, be more and more subject to now the favor in market.How to adopt efficient, economic method to produce the inner race part of high-quality, become urgent problem in production.The grinding process of traditional inner race spherical outside surface adopts forward filing, and it belongs to intermittent grinding and easily causes vibration because grinding force suddenlys change, and proposes oblique filing, improve surface quality and machining accuracy for this phenomenon.
Inner race is as the part on a basis, assembling for automobile has great impact, past, this part mainly adopted machining, because the intensity of material, hardness all can not be guaranteed, in actual use often there is part injury and need the phenomenon of constantly replacing in meeting, and this product generally adopts cold forming method at present, but technological design mainly still by rule of thumb, all also there is irrational phenomenon in distribution, the mould structure design of processing passage, needs further investigation.
Utility model content
The purpose of this utility model is: for the defect of prior art, propose that a kind of inner race is counter forces down mould, this mould not only further increases prestressing force, decreases anti-risk of squeezing mould radial direction cracking, improve the life-span of mould greatly, and consumptive material is few, cost is low, simultaneously Optimizing die structure, stress raiser on mould is removed, this part is transferred on upper punch, both decreased the use to more valuable mold materials, by improve the life-span.
The technical scheme that the utility model adopts is: a kind of inner race is counter forces down mould, comprise counterdie and pressure block one, pressure block one is positioned at the below of counterdie, and the arranged on left and right sides of pressure block one is respectively equipped with stripping attachment and pressure block two, and wherein the top of stripping attachment is provided with upper punch.
In the utility model: the top of described counterdie is provided with fairlead, the side of fairlead is connected with upper punch by drift cover, and the top of upper punch is provided with fill block.
After adopting technique scheme, the beneficial effects of the utility model are: the utility model not only further increases prestressing force, decrease anti-risk of squeezing mould radial direction cracking, improve the life-span of mould greatly, and consumptive material is few, cost is low, Optimizing die structure, removes the stress raiser on mould, this part is transferred on upper punch simultaneously, both the use to more valuable mold materials had been decreased, by improve the life-span.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1. fill block; 2. drift cover; 3. upper punch; 4. fairlead; 5. counterdie; 6. stripping attachment; 7. pressure block one; 8. pressure block two.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As seen from Figure 1, a kind of inner race is counter forces down mould, it is characterized in that: comprise counterdie 5 and pressure block 1, pressure block 1 is positioned at the below of counterdie 5, the arranged on left and right sides of pressure block 1 is respectively equipped with stripping attachment 6 and pressure block 28, and wherein the top of stripping attachment 6 is provided with upper punch 3.The top of described counterdie 5 is provided with fairlead 4, and the side of fairlead 4 is connected with upper punch 3 by drift cover 2, and the top of upper punch 3 is provided with fill block 1.
Above detailed description of the invention of the present utility model is described, but the utility model is not limited to above description.For a person skilled in the art, any equal amendment to the technical program and substitute be all among scope of the present utility model.Therefore, not departing from the equalization conversion and amendment done under spirit and scope of the present utility model, all should be encompassed in scope of the present utility model.
