Abstract
The invention discloses a production process of a bearing ring, which comprises the following steps of (1) blanking; (2) intermediate frequency heating; (3) forming a pier cake; (4) heat treatment; (5) carrying out numerical control turning; (6) automatic monitoring; (7) performing full inspection; (8) delivering goods; the strength of the work piece is increased by heat treatment and the increase of defective products is prevented by secondary inspection.
Description
Technical Field
The invention relates to the technical field of complex bearing processing, in particular to a production process of a bearing ring.
Background
Bearing rings (bearing rings) are annular parts of radial rolling bearings with one or several raceways.
Traditional bearing ring detects the completion back to the work piece through external diameter bearing ring, and the work piece is direct can the delivery, and when work piece delivery back, the defective work appears easily, and directly processes through the steel pipe when traditional technology, and the intensity of steel pipe is low excessively, leads to follow-up practical in-process practical life to subtract the weak point.
Disclosure of Invention
The invention aims to provide a bearing ring production process, which increases the strength of a workpiece through heat treatment and prevents defective products from increasing through secondary inspection.
The technical purpose of the invention is realized by the following technical scheme:
a production process of a bearing ring comprises the following steps:
(1) blanking: blanking the steel pipe by staff;
(2) intermediate-frequency heating: placing the steel pipe into an intermediate frequency furnace by staff for heating for 1-2 hours;
(3) forming a pier cake: placing the heated steel pipe into a punch press for punching;
(4) and (3) heat treatment: placing the formed steel pipe into a heat treatment heating furnace for heat treatment;
(5) numerical control turning: the workpiece after heat treatment is prevented from turning in a numerically controlled lathe, and the turning deviation is plus or minus 0.1mm
(6) Automatic monitoring: placing the workpiece into an outer diameter bearing ring detection device for detection, and manually cleaning the unqualified workpiece;
(7) and (4) performing a complete test: the staff again carries out secondary detection on the bearing ring, and then screens the unqualified products of the bearing ring;
(8) and (4) delivery: and (5) packing and sending qualified products by the staff.
Preferably, the material of the steel pipe in the step (1) is AISI 52100.
Preferably, the model of the intermediate frequency furnace in the step (2) is GW-0.05 t.
Preferably, the model of the intermediate frequency furnace in the step (2) is GW-0.05 t.
Preferably, the model of the punch press in the step (3) is J36-80 OE.
Preferably, the heating furnace model in the step (4) is YYL YQL-15.
Preferably, the turning deviation in the step (5) is-1 mm.
Has the advantages that: the intermediate frequency heating is used for facilitating the subsequent stamping, the forming is more desirable, and the heat treatment is used for increasing the strength of the steel pipe; the increase of defective products is prevented by the secondary inspection by the user.
Detailed Description

It should also be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention.
The production process of the bearing ring is characterized by comprising the following steps of:
(1) blanking: the staff blanking the steel pipe, the material of the steel pipe is AISI 52100;
(2) intermediate-frequency heating: the staff places the steel pipe in an intermediate frequency furnace with model number of GW-0.05 t for heating, and the intermediate frequency heating time is 1.30 hours;
(3) forming a pier cake: placing the heated steel pipe into a punch press with the model of J36-80OE for punching;
(4) and (3) heat treatment: placing the formed steel pipe into a heat treatment heating furnace with the model of YYL YQL-15 for heat treatment;
(5) numerical control turning: the workpiece after heat treatment is prevented from turning in a numerically controlled lathe, and the turning deviation is-1 mm
(6) Automatic monitoring: placing the workpiece into an outer diameter bearing ring detection device for detection, and manually cleaning the unqualified workpiece;
(7) and (4) performing a complete test: the staff again carries out secondary detection on the bearing ring, and then screens the unqualified products of the bearing ring;
(8) and (4) delivery: and (5) packing and sending qualified products by the staff.
The traditional process comprises the following steps: the strength is low, the service life is short, and the subsequent delivery is more defective;
the above process: the strength of the steel ring was increased by heat treatment, and the generation of inferior goods after shipment was checked by a second time.
