Abstract
The invention discloses a method for combining and processing hot riveting and cold grinding of a copper entity retainer with a rivet. The method comprises the following steps of step one, designing of a riveting mould which is used for supporting a retainer to not be deformed, wherein the riveting mould is a steel mould of which the hardness is greater than 40 HRC, the end surface size of the riveting mould is the same as that of an inner ring of a bearing, and the outer diameter size of the riveting mould must be made in a way of matching with an outer component; step two, the hot riveting before cold grinding, wherein a rivet head of the entity retainer with the rivet is heated by utilizing an electric heating riveting machine, the stress of the rivet head before the cold grinding is removed by high-temperature tempering, and meanwhile, hot riveting can be carried out on the rivet head through a riveting head; step three, cold grinding processing technology of the rivet entity retainer with the rivet, wherein cold grinding processing must be carried out on the rivet head by adopting a riveting head of a grinding riveting machine after the hot riveting is carried out on the rivet head, the height after the cold grinding must be well adjusted during cold grinding processing, and a cold grinding machine needs to be located. According to the method for combining and processing the hot riveting and the cold grinding of the copper entity retainer with the rivet, disclosed by the invention, the quality problem of cracks on the riveting head of the retainer is avoided, and the product quality requirement is ensured.
Description
Technical field
The present invention relates to solid bearing cage riveted processing method, specifically relate to one and carry rivet copper solid bearing cage electrical heating riveted and cold roll combinational processing method.
Background technology
Carrying rivet copper solid bearing cage (does not design separately rivet, keeps stand to process square toes by the processing method of car system, link with the square hole of retainer lid.), kind of bearings retainer problem: the 1st, if only adopt electrical heating technique for riveting, riveted face there will be electricity sparking to cause the appearance quality of pockmark because contact is improper.The 2nd, if only take cold roll technique, the retainer after processing there will be the phenomenon of distortion and crackle.So solving and carrying rivet copper solid cage electrical heating riveted appearance quality or the distortion of cold roll retainer and crack problem is a tackling key problem difficult problem.
Summary of the invention
The technical problem to be solved in the present invention is, provide a kind of can solve carry its retainer presentation quality of rivet copper solid cage bearing and distortion, crackle quality problems carry rivet copper solid bearing cage electrical heating riveted and cold roll combinational processing method.
The technical scheme adopting is:
One carries the rivet hot of rivet copper solid cage and closes and cold roll combinational processing method, the method comprises that a kind of riveted mold of design supports that to carry rivet solid cage indeformable and increase the technique processing method that carries the tempering of manufactured head electrical heating high-temperature and remove stress before cold roll, and its processing method comprises the following steps:
Step 1: design a kind of riveted mold support retainer indeformable
Riveted mold is that hardness is greater 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 of outer ring and roller combination, its size that manufactures gap is limited to according to the size of product: 0.04mm～0.10mm, it is indeformable that realization support carries rivet solid cage.
Step 2: the rivet hot before cold roll is closed
Utilize electrical heating rivet driver (commercial equipment) heating to carry the manufactured head of rivet solid cage, make manufactured head high tempering remove cold roll stress in the past, simultaneously by die to manufactured head rivet hot, to expose manufactured head high pressure to 1/3～1/2 of retainer lid, proceed to next step and carry out again cold roll.
Step 3: carry rivet solid cage cold roll processing technology
after manufactured head rivet hot, must adopt the die that rolls lock seaming machine (commercial equipment) to carry out cold roll processing, cold roll adds man-hour, must adjust the height after cold roll, and cold grinding is located at once;
initial workpiece must check the quality after cold roll, if also have crackle, must adjust the manufactured head height that exposes retainer lid after 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.
Above-mentioned manufactured head is square toes manufactured head.
The present invention is compared with traditional processing method, increase a kind of riveted mold and avoided retainer problem on deformation and retainer riveted head high-temperature tempering process processing method, the quality problems of retainer riveted cephalic slit line are avoided, ensure product quality requirement, avoided the quality problems that occur retainer distortion and crackle to lay the foundation for processing later carries rivet copper solid cage bearing cold roll.

Detailed description of the invention
One carries the rivet hot of rivet copper solid cage and closes and cold roll combinational processing method, the method comprises that a kind of riveted mold of design supports that to carry rivet solid cage indeformable and increase the technique processing method that carries the tempering of manufactured head electrical heating high-temperature and remove stress before cold roll, and its processing method comprises the following steps:
Step 1: design a kind of riveted mold support retainer indeformable
Riveted mold 9 is greater than 40HRC steel mold for hardness, riveted mold 9 face sizes are identical with bearing inner race 2 face sizes, the outside dimension of riveted mold 9 must manufacture with the outer assembly that outer ring 1 and roller 3 combine, its size that manufactures gap is limited to according to the size of product: 0.04mm～0.10mm, it is indeformable that realization support carries rivet solid cage 4.
Step 2: the rivet hot before cold roll is closed
Utilize 5 heating of electrical heating rivet driver to carry the manufactured head 7 of the square toes of rivet solid cage 4.Make manufactured head 7 high temperings remove cold roll stress in the past, pass through die 6 to manufactured head 7 rivet hots simultaneously, will expose manufactured head 7 high pressure to 1/3～1/2 of retainer lid 8, proceed to next step and carry out again cold roll.
Step 3: carry rivet solid cage cold roll processing technology
after manufactured head 7 rivet hots, must adopt the die 6 that rolls lock seaming machine 10 to carry out cold roll processing, cold roll adds man-hour, must adjust the height after cold roll, and cold grinding is located at once;
initial workpiece must check the quality after cold roll, if also have crackle, must adjust expose retainer lid 8 after electrical heating manufactured head 7 highly, if initial workpiece is qualified, then produce in batches.
