Abstract

The present invention relates to a kind of bearing ring forging process temperature control methods, belong to bearing ring technical field.Main technical schemes are as follows: a kind of bearing ring forging process temperature control method, after bearing ring forging is put into burning stove heating, forged using Single arm, after punching returns again to hydraulic press reaming, into combustion furnace reheating, heat preservation, finally arrive Ring Rolling Machine.The burning stove heating, temperature reach 1150-1200 DEG C;The combustion furnace reheating, temperature reaches 1150-1200 DEG C, and keeps the temperature 2.5-3 hours, and 800-900 DEG C of temperature of bearing ring forging is made.Temperature of the present invention rationally, effectively, guarantees quality of the forging when rolling over lasso, avoids the occurrence of rotten material, waste material.Forging rolles over into bearing race again, and qualification rate is up to 100%.

Description

A kind of bearing ring forging process temperature control method
Technical field
The present invention relates to bearing ring technical fields, and in particular to a kind of bearing ring forging process temperature control method.
Background technique
Bearing ring is a kind of ring-shaped work pieces.Currently, a kind of bearing holder (housing, cover) made of 100CrMnMoSi alloy material Circle, since material cooling rate is too fast, when forging be put into Ring Rolling Machine start roll over part during, with other materials roll over forging temperature phase Instead, instantaneous temperature reduces more than 100 degree, causes roundness, the concentricity of workpiece after processing poor, and machine-shaping rate only has 60% left side It is right.
Summary of the invention
The present invention provides a kind of bearing ring forging process temperature control method, solves existing 100CrMnMoSi alloy material Bearing ring, product roundness, concentricity are poor after processing, and the low problem of machine-shaping rate avoids the occurrence of rotten material, waste material.This The technical solution of invention is as follows: bearing ring forging is put into burning stove heating by a kind of bearing ring forging process temperature control method Afterwards, it is forged using Single arm, after punching returns again to hydraulic press reaming, into combustion furnace reheating, heat preservation, finally arrive rolling ring Machine.
Further, the burning stove heating, temperature reach 1150-1200 DEG C;The combustion furnace reheating, temperature reach To 1150-1200 DEG C, and 2.5-3 hours are kept the temperature, 800-900 DEG C of temperature of bearing ring forging is made.
Further, the burning stove heating, temperature reach 1180 DEG C, and the combustion furnace reheating, temperature reaches 1180℃。
Beneficial effects of the present invention are as follows: the temperature of the bearing ring processing of 100CrMnMoSi alloy material is reasonable, has Effect guarantees quality of the forging when rolling over lasso, avoids the occurrence of rotten material, waste material.Forging rolles over into bearing race again, and qualification rate is up to 100%.
Detailed description of the invention
Fig. 1 is process flow chart of the invention.
Specific embodiment
The present invention is described further combined with specific embodiments below and explains.
Embodiment 1
It takes 10 forging to be put into burning stove heating, when forging temperature reaches 1150 DEG C, is forged to Single arm, punching turns again After hydraulic press reaming, into 1150 DEG C of combustion furnace reheating temperature, heat preservation 2.5 hours, (bearing is survived to Ring Rolling Machine Circle), 800 DEG C of terminal temperature.
Examine product qualified rate 100%.
Embodiment 2
It takes 10 forging to be put into burning stove heating, when forging temperature reaches 1180 DEG C, is forged to Single arm, punching turns again After hydraulic press reaming, into 1180 DEG C of combustion furnace reheating temperature, heat preservation 3 hours, (bearing race) is survived to Ring Rolling Machine, 900 DEG C of terminal temperature.Examine product qualified rate 100%.
Embodiment 3
It takes 10 forging to be put into burning stove heating, when forging temperature reaches 1200 DEG C, is forged to Single arm, punching turns again After hydraulic press reaming, into 1200 DEG C of combustion furnace reheating temperature, heat preservation 3 hours, (bearing race) is survived to Ring Rolling Machine, 900 DEG C of terminal temperature.Examine product qualified rate 100%.
Above-described embodiment is only intended to citing and explanation of the invention, and is not intended to limit the invention to described In scope of embodiments.Furthermore it will be appreciated by persons skilled in the art that the present invention is not limited to the above embodiment, according to this hair Bright introduction can also make more kinds of variants and modifications, these variants and modifications all fall within present invention model claimed In enclosing.
