Abstract

The invention relates to a perforation positioning process for set forging production of a bearing blank outer ring and an outer ring on a high-speed upsetting forging machine. The process comprises the following steps of: forming a small positioning lug boss on a finish forging blank according to the size of the inner hole of each outer ring set forging outer ring product, wherein the height of the small positioning lug boss is 2.5 to 3.5 millimeters, and the clearance between the outside diameter phi A of the small positioning lug boss and the profile inside diameter phi B of a perforation female die is 0.5 to 0.7 millimeter; when the finish forging blank is conveyed to a perforation sub set station through a clamp, guiding the small positioning lug boss on the blank into the profile inside diameter of the perforation female die; and positioning the small positioning lug boss of the blank on the profile inside diameter of the perforation female die during perforation so as to ensure that the blank is positioned at the central position during perforation. The process ensures that the blank is positioned at the central position during perforation and sub set, ensures the quality of the product, and can fully control the wall thickness difference in a specified range; and the adjusting frequency of the clamp is reduced during production, the production efficiency is improved, the rework frequency caused by excessive wall thickness difference is reduced to zero, an eccentricity turning correction process is not needed, and the process is suitable for production of outer ring set forging outer ring products.

Description

The perforation positioning process of producing is forged at the Balance mechanism cover in bearing blank outer ring and outer ring
Technical field
The invention belongs to high speed upsetting technical field, relate to and a kind ofly be adapted to produce outer ring sleeve and forge the bearing blank outer ring of the product of outer ring and forge the perforation positioning process of production with the outer ring at the Balance mechanism cover.
Background technology
The technology that bearing blank outer ring product adopts outer ring sleeve to forge the outer ring forms a complete production network, when outer ring sleeve is forged outer ring production, because branch cover size and small head external diameter as the outer ring of ringlet only differ 0.6-0.8mm, namely the bore a hole outside dimension of die and ringlet outside dimension approaches, and can't come to locate to the ringlet external diameter at perforation die processing locating slot; Simultaneously in drift hammer one side, because the raceway angles of outer ring is big, can't give suitable location of drift hammer, this perforation of ringlet, divides easily off-centre of cover position so that aborning.This has brought some unfavorable factors to production: the one, and in forging production, the operative employee need adjust clamp repeatedly, and the workload of adjustment has strengthened, and production efficiency has reduced, and has also produced the overproof product of a lot of wall thickness differences simultaneously; The 2nd, owing in the product of producing the overproof product of a lot of wall thickness differences is arranged, brought difficulty to sorting, need do over again repeatedly; The 3rd, sorting is sometimes done over again repeatedly and can't be dealt with problems, and usually will increase the operation of car one cutter endoporus school off-centre.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of bearing blank outer ring and outer ring and on the high speed upsetter, overlap the perforation positioning process of forging production.
The present invention solves the technical method that its technical problem adopts: the perforation positioning process of producing is forged at the Balance mechanism cover in a kind of bearing blank outer ring and outer ring, and its processing step is:
The first step: according to the interior hole size of every kind of outer ring sleeve forging outer ring product, be that 0.5-0.7 mm locates small boss in high gap for 2.5-3.5mm, external diameter Φ A and perforation die profile internal diameter Φ B of material base shaping of finish-forging;
Second step: when the finish-forging material base is sent to perforation branch cover station by clamp, location small boss on the material base imports perforation die profile internal diameter, location small boss with blank when perforation is positioned on the profile internal diameter of perforation die, and blank is in the center when having guaranteed perforation.
Described location small boss height is 3mm, and location small boss external diameter Φ A is 0.6 mm with the gap of perforation die profile internal diameter Φ B.
The invention has the beneficial effects as follows: the material base at finish-forging is provided with the location small boss, location small boss with blank when perforation is positioned on the profile internal diameter of perforation die, blank is in the center when having guaranteed perforation, branch cover, guaranteed the quality of product, Wall-Thickness Difference can be controlled within the limits prescribed fully; Reduce clamp during production and adjusted number of times, improved production efficiency, because the overproof number of doing over again that causes of Wall-Thickness Difference also is reduced to zero, need not have increased turning and proofread and correct eccentric operation, be adapted to the production that outer ring sleeve is forged the product of outer ring.
Description of drawings
Fig. 1 is the structural representation of finish-forging station material base of the present invention.
Fig. 2 is the structural representation of the location situation of small boss of the present invention in the perforation die.
Among the figure: 1-material base, 2-location small boss, 3-perforation die, Φ A-location small boss external diameter, Φ B-perforation die profile internal diameter.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
Referring to Fig. 1 and Fig. 2, the perforation positioning process of producing is forged at the Balance mechanism cover in a kind of bearing blank outer ring and outer ring, and its processing step is:
The first step: according to the interior hole size of every kind of outer ring sleeve forging outer ring product, be that 0.5-0.7 mm locates small boss 2 in high gap for 2.5-3.5mm, external diameter Φ A and perforation die profile internal diameter Φ B of material base 1 shaping of finish-forging;
Second step: when the finish-forging material base is sent to perforation branch cover station by clamp, location small boss 2 on the material base 1 imports perforation die profile internal diameter Φ B, location small boss 2 with blank 1 when perforation is positioned on the profile internal diameter of perforation die 3, and blank 1 is in the center when having guaranteed perforation.
In this example, according to the interior hole size of bearing blank outer ring product, be the location small boss 2 of 0.6 mm in high gap for 3mm, location small boss external diameter Φ A and perforation die profile internal diameter Φ B of material base 1 shaping of finish-forging.
The present invention is provided with the location small boss at the material base of finish-forging, location small boss with blank when perforation is positioned on the profile internal diameter of perforation die, blank is in the center when having guaranteed perforation, branch cover, has guaranteed the quality of product, and Wall-Thickness Difference can be controlled within the limits prescribed fully; Reduced clamp during production and adjusted number of times, improved production efficiency, because the overproof number of doing over again that causes of Wall-Thickness Difference also is reduced to zero, need not have increased turning and proofread and correct eccentric operation.Be adapted to outer snare and forge the production of the product of outer ring.
