Abstract

The invention discloses a forging technology of a rolling bearing ring. The forging technology is a hot forging technology and comprises steps as follows: blanking, heating forging, extrusion forming, ring rolling and shaping, wherein the step of blanking means shearing blanking; the step of heating forging comprises initial forging and final forging, the temperature of the initial forging ranges from 1,060 DEG C to 1,080 DEG C, the heating time is 30-35 min, and the heat is preserved for 15-17 mins at the temperature of 1,060-1,080 DEG C; the temperature of the final forging ranges from 820 DEG C to 860 DEG C, the heating time is 25-30 min, and the heat preservation time is 15-17 mins. According to the scheme, the forging quality can be improved, the service lifetime of a forged piece is prolonged, meanwhile, the utilization rate of the material is increased, and the cost is reduced.

Description

A kind of Forging Technology of rolling bearing lasso
Technical field
The present invention relates to Technology for Heating Processing field, particularly relate to a kind of Forging Technology of rolling bearing lasso.
Background technology
Bearing is a kind of very important parts in contemporary plant equipment.The forging of bearing ring is a more typical class processing in machinery forging.
The main purpose of the forging processing of bearing ring has two: one to be obtain the blank close with shape of product; Another eliminates metal inside defect, improves metal inside tissue, and metal streamline is distributed rationally.
At present, bearing ring forging adopts coal or heated by natural gas, and fire consumption is large, and the heat time is longer, the defect such as have that stock utilization is low, cost is high, forging service life is low.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of Forging Technology of rolling bearing lasso, can improve forging quality, extends the service life of forging, improves the utilization rate of material simultaneously, reduces cost.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the Forging Technology providing a kind of rolling bearing lasso, for thermal forging technology, comprise: blanking-heats forged-extrusion molding-rolling-shaping, described blanking is shearing blanking, described heats forged comprises begin forging and finish-forging, the described temperature begun when forging is 1060-1080 DEG C, heat time is 30-35 minute, and 15-17 minute is incubated at 1060-1080 DEG C, temperature during described finish-forging is 820-860 DEG C, and the heat time is 25-30 minute, and temperature retention time is 15-17 minute.
