Abstract

One carries rivet copper solid cage rivet hot conjunction and cold roll combinational processing method, comprise the following steps: step one: it is indeformable that a kind of riveted mold of design supports retainer, riveted mold is that hardness is more than 40HRC steel mold, riveted mold face size is identical with bearing inner race face size, and the outside dimension of riveted mold must manufacture with outer assembly；Step 2: the rivet hot before cold roll is closed, utilizes the heating of electrical heating rivet driver to carry the manufactured head of rivet solid cage so that manufactured head high tempering removes the stress before cold roll, simultaneously by die to manufactured head rivet hot；Step 3: carry rivet solid cage cold roll processing technique, after manufactured head rivet hot, must adopt the die rolling lock seaming machine to carry out cold roll processing at once, and cold roll adds man-hour, must adjust the height after cold roll, and be positioned by cold grinding.Present invention, avoiding the quality problems of retainer riveted cephalic slit stricture of vagina, it is ensured that product quality requirement.

Description

One carries rivet copper solid cage rivet hot conjunction and cold roll combinational processing method
Technical field
The present invention relates to solid bearing cage riveted processing method, be specifically related to one and carry rivet copper solid bearing cage electrical heating riveted and cold roll combinational processing method.
Background technology
(not individually designed rivet keeps stand to process square toes by the processing method of car, links with the square hole of retainer lid to carry rivet copper solid bearing cage.), kind of bearings retainer problem: 1 is if only with electrical heating technique for riveting, riveted face improper there will be electricity sparking owing to contacting and causes the appearance quality of pockmark.2 is if only taking cold roll technique, and the retainer after processing there will be the phenomenon of deformation and crackle.So solving to carry rivet copper solid cage electrical heating riveted appearance quality or the deformation of cold roll retainer with crack problem is a tackling key problem difficult problem.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of can solve the problem that carry rivet its retainer presentation quality of copper solid cage bearing and deformation, crackle quality problems carry rivet copper solid bearing cage electrical heating riveted and cold roll combinational processing method.
The technical scheme is that
One carries rivet copper solid cage rivet hot conjunction and cold roll combinational processing method, the method includes designing a kind of riveted mold and supports that to carry rivet solid cage indeformable and increase and carry manufactured head electrical heating high-temperature tempering and remove the technique processing method of stress before cold roll, and its processing method comprises the following steps:
Step one: it is indeformable that a kind of riveted mold of design supports retainer
Riveted mold is that hardness is more than 40HRC steel mold, riveted mold face size is identical with bearing inner race face size, the outside dimension of riveted mold must manufacture with the outer assembly that outer ring and roller are combined, its size manufacturing gap is limited to according to the size of product: 0.04mm～0.10mm, it is achieved it is indeformable that support carries rivet solid cage.
Step 2: the rivet hot before cold roll is closed
Electrical heating rivet driver (commercial equipment) heating is utilized to carry the manufactured head of rivet solid cage, stress before making manufactured head high tempering remove cold roll, simultaneously by die to manufactured head rivet hot, by exposing the manufactured head high pressure of retainer lid to 1/3～1/2, proceed to next step and carry out cold roll again.
Step 3: carry rivet solid cage cold roll processing technique
1. after manufactured head rivet hot, the die rolling lock seaming machine (commercial equipment) must being adopted to carry out cold roll processing, cold roll adds man-hour, must adjust the height after cold roll, and be positioned by cold grinding at once；
2. initial workpiece has to check for the quality after cold roll, if also having crackle, it is necessary to expose the manufactured head height of retainer lid after adjusting electrical heating, if initial workpiece is qualified, then produce in batches.
The above closes and cold roll combinational processing method for carrying rivet copper solid cage rivet weld.
Above-mentioned manufactured head is square toes manufactured head.
The present invention is compared with traditional processing method, add a kind of riveted mold and avoid retainer problem on deformation and retainer riveted head high-temperature tempering process processing method, avoid the quality problems of retainer riveted cephalic slit stricture of vagina, ensure that product quality requirement, avoid the occurrence of retainer deformation and the quality problems of crackle lay the foundation for carrying rivet copper solid cage bearing cold roll with post-treatment.

Detailed description of the invention
One carries rivet copper solid cage rivet hot conjunction and cold roll combinational processing method, the method includes designing a kind of riveted mold and supports that to carry rivet solid cage indeformable and increase and carry manufactured head electrical heating high-temperature tempering and remove the technique processing method of stress before cold roll, and its processing method comprises the following steps:
Step one: it is indeformable that a kind of riveted mold of design supports retainer
Riveted mold 9 is that hardness is more than 40HRC steel mold, riveted mold 9 face size is identical with bearing inner race 2 face size, the outside dimension of riveted mold 9 must manufacture with the outer assembly that outer ring 1 and roller 3 are combined, its size manufacturing gap is limited to according to the size of product: 0.04mm～0.10mm, it is achieved it is indeformable that support carries rivet solid cage 4.
Step 2: the rivet hot before cold roll is closed
Electrical heating rivet driver 5 is utilized to heat the manufactured head 7 of the square toes carrying rivet solid cage 4.Make manufactured head 7 high tempering remove the stress before cold roll, simultaneously by die 6 to manufactured head 7 rivet hot, by exposing manufactured head 7 high pressure of retainer lid 8 to 1/3～1/2, proceed to next step and carry out cold roll again.
Step 3: carry rivet solid cage cold roll processing technique
1. after manufactured head 7 rivet hot, the die 6 rolling lock seaming machine 10 must being adopted to carry out cold roll processing, cold roll adds man-hour, must adjust the height after cold roll, and be positioned by cold grinding at once；
2. initial workpiece has to check for the quality after cold roll, if also having crackle, it is necessary to exposes manufactured head 7 height of retainer lid 8 after adjusting electrical heating, if initial workpiece is qualified, then produces in batches.
The above closes and cold roll combinational processing method for carrying rivet copper solid cage rivet weld.
