Abstract
The present invention is a kind of Forging Technology that bearing blank is produced that is used for.Be to change production method that the explained hereafter flow process can only be produced model bearing blank one cover of the same race in the existing domestic and international bearing blank production.This invention is on former technology basis, adopt secondary core material method, make full use of raw material and produce the bearing blank of two kinds of models, use two explained hereafter flow processs, just can produce three kinds of supporting model bearing blanks, the present invention is that a kind of bearing blank that can shorten is produced and to be solved the supporting of bearing the same period.The utilization rate of raising material of enhancing productivity and the novel Forging Technology of the abundant energy savings of energy.
Description
The present invention is the novel Forging Technology of a kind of bearing blank.Specifically, be exactly to forge in the production at bearing blank, utilize the secondary core material to produce the technology of two kinds of above bearing blanks of model.
In existing domestic and international bearing blank was produced, what generally adopt was technologies such as cover forging, the forging of high speed pier, warm extrusion pressure.But all technologies in an explained hereafter flow process, can only be produced the inside and outside mao mao's base of a cover bearing of model of the same race, and the raw materials consumption height, can not make full use of.In the cover forging process, raw materials consumption height, the waste of ring heelpiece in mainly being meant.With 206 bearing blanks is example, heelpiece technology heavily is 19.6 grams, encircle 13% of blank weight in accounting for, account for 6% of 206 bearing blank gross weights, in bearing blank high speed pier forging process, though production output is higher, but, ring heelpiece waste of material in not only existing, and existing the waste of material that in forging process, produces endless belt, warm extrusion technology is though output is not as high speed pier forging process, but produce the waste of material of endless belt in also existing in ring heelpiece and the forging process, and the production difficulty is bigger.
Purpose of the present invention, provide a kind of technology that can produce two kinds of model bearing blanks simultaneously, solve other part of long-term existence bearing and do not match problem, can shorten the production cycle, enhance productivity and stock utilization, and energy-conservation novel Forging Technology.
The present invention is in bearing blank is produced, and under the rational situation of technology, changes the forging method that an explained hereafter flow process is produced model bearing blank one cover of the same race.This technology is: with an explained hereafter flow process, make full use of raw material, produce bearing blank one cover of model of the same race, and other plants the interior ring of a bearing blank or the outer shroud of model to be with output.That is: the material section will be become as required under the raw material, through conducting forging processing, the outer shroud of a bearing of output or interior ring blank and a core material, a core material is through conducting forging processing, outer race of output or interior ring blank and a secondary core material, the secondary core material is again through conducting forging processing, the outer shroud of the 3rd bearing of output or interior ring blank, like this, with two explained hereafter flow processs, just can produce the bearing inner and outer ring blank of three kinds of models, and can be applied to solve the supporting of bearing.
Below in conjunction with embodiment and accompanying drawing thereof, be described in detail the present invention:
With 204,205,206 model bearing blanks is example:
Figure closes and forges the process chart that encircles one of blank in 204 at one: 206.
Among the figure: 1, material section, 2, pier is thick, 3, the outer ring material behind the core material, 4, flatten, 5, ream forming, 6, core material, 7, the core material pier is thick, 8, extruding, 9, the material of the outer ring behind the secondary core material, 10, the secondary core material, 11, pier is thick, 12, extruding, 13, be shaped towards heelpiece.
Figure two, 205 closes the process chart of forging one of 204 outer shroud blank.
Among the figure: 21, material section, 22, pier is thick, and 23, extruding, 24,205 outer shrouds behind the core material, 25, core material, 26, outer ring material, 27, flatten 28,204 outer shroud blank ream formings, 29, secondary core material, 30, pier is thick, 31, squeeze extruding, 32, in the heelpiece 205 loop formings.
According to figure one, introduce 206 and close the technology of forging one of 204 interior ring blank, on demand the round bar blanking is become material section (1), material section heating back pier thick (2), the thick backlash core material of pier, at this moment outer ring material (3) and a core material (6) have just been produced, outer ring material (3), 206 outer shroud blank material just, outer ring material (3) is through flattening (4) when technology is asked highly, after the reaming (5), 206 outer shroud blank forming core materials (6) are behind pier thick (7), and extruding (8) is behind the secondary core material, and the outer ring material has formed ring blank (9) in 206, secondary core material (10) is through pier thick (11), extruding (12) behind heelpiece (13), ring forms in 204.
According to figure two, introduce 205 and close technology of forging 204 outer shroud blanks: on demand the round bar blanking is become material section (21), the material section is through heating pier thick (22), push (23) after pier is thick, extrusion process outer ring material is 205 outer shroud blank forming processes just, through behind core material, just produced one 205 outer shroud blank (24), with a core material (25), core material through secondary behind core material, outer ring material (26) and a secondary core material (29) have been produced, outer ring material (26) is through flattening (27) when 204 outer shroud blanks are asked highly, reaming (28) 204 outer shroud blank formings, secondary core material (20), behind pier thick (30), extruding (31), ring blank formings (32) in 205 behind the heelpiece.
Through two technological processes of above 205,206 model bearing blanks, just fecund has gone out the bearing blank of a cover 204 models.
The present invention compares with existing technology, can save material about 2 percent five, reduced the waste of heelpiece material, and can reduce about 1/4th man-hours than former technology, can improve output about about 1/3rd, save heat energy, can also make the forged material uniform specification, be convenient to management.
Claims (1)
- A kind of Forging Technology that is used for bearing inner and outer rings blank, it is characterized in that the core material (6) (25) that produces, after conducting forging processing, produce secondary core material (10) (29) again, and the reprocessing technique of secondary core material.
