Process steps of deep groove ball bearing processing

2021-08-25

Bearings are very important for mechanical equipment. If the lack of bearings will directly affect the operation of the equipment, have you heard of deep groove ball bearings? This is a relatively common one. Deep groove ball bearings undergo process procedures In this way, the quality has been improved, which can improve the appearance of the bearing and reduce the degree of friction. The following editor will share with you the process steps of deep groove ball bearing processing:

 groove ball bearings

1. Tube blank processing: The bearing steel is heated to 1150℃~1200℃ in a heating furnace, and the heated tube blank is pierced by a piercing machine to make a capillary tube;

2. Spheroidizing annealing: the capillary tube is spheroidizing annealing, and the hardness of the capillary tube after annealing is in the range of HRB88~94;

3. Hot rolling of tube billet: send the annealed capillary tube into a heating furnace for secondary soaking; the capillary tube after the second soaking process is reduced in diameter, wall reduced, and stretched to form a waste tube;

4. Tube blank shaping and cutting: the waste tube passes through the sizing unit for sizing and shaping, and then straightening and cutting to form a set;

5. Recrystallization annealing: The kit is subjected to recrystallization annealing treatment to eliminate work hardening, so as to facilitate the implementation of cold rolling;

6. Soft grinding kit: the double end face of the kit is soft ground first, then the outer circle of the kit is soft ground, the double end face is ground first, and then the outer circle is ground. The outer circle is through-type grinding. , To ensure that the outer diameter surface of the part is always on the same plane as the pallet, to ensure that the outer diameter taper is within the control range, adjust the angle relationship between the two grinding wheels in the double end surface grinding process, control the parallel difference of the end surface, and the end surface accuracy as a subsequent process The processing datum plane; the outer circle is processed by centerless grinding;

7. Set fine hole: Drill stop bolt holes and oil holes on the surface of the set, and rough the surface of the inner hole of the set to prepare for the surface of the inner hole of the cold rolling;

8. Cold rolling expansion kit: For the cold rolling expansion of deep groove ball bearing ring channel, the core roller feed speed has 6 stages in the cold rolling process, and the speed range is 0.4mm/s~1.0mm/s. The trajectory of the curve in one processing cycle is fast, slow, slow, until it stops; the rolling time is between 6s and 14s, and the rolling force is 80KN;

9. Turning kit: chamfer the kit and seal the groove;

10. Fine grinding kit: fine grinding kit to improve the surface accuracy of the kit;

11. Install the bearing: put balls between the rings, install the cage, inject grease, install the seals, and complete the assembly of the deep groove ball bearing.

In order to give you a more comprehensive understanding of the steps of the deep groove ball bearing processing technology, the editor has sorted it out for you, and hopes to help you. If you want to buy high-quality bearings, roller bearings, deep groove ball bearings and other products, you may wish to consider our Jinan Kaiming bearing manufacturer.

  Roller bearing is a kind of bearing. Bearing is a kind of parts that occupy a key position in various mechanical equipment. Its precision and integrity are important factors that determine its ability to operate, but bearings are generally the most worn in machinery. In order to ensure the service life of the bearing, some maintenance and maintenance measures are necessary for it. The following editor will introduce how to maintain bearings.

       1. Energy-saving heat treatment: Choose new thermal insulation materials to improve the energy efficiency of heat treatment equipment; optimize the heat treatment process, increase the process output, and give full play to the capabilities of the equipment.

       2. Precision heat treatment Precision heat treatment is to fully ensure the stability of the optimized process, achieve small (or zero) product quality dispersion, zero heat treatment distortion, reduce grinding allowance, improve production efficiency, and save materials.

 

       3. Less non-oxidizing heat treatment by using protective atmosphere heating instead of oxidizing atmosphere heating to a controlled atmosphere heating with precise control of carbon potential and nitrogen potential. After heat treatment, the performance of parts is improved, and heat treatment defects such as oxidation, decarburization and cracks are greatly reduced. The finishing allowance after heat treatment is reduced, which improves material utilization and machining efficiency.

       4. Clean heat treatment Waste water, waste gas, waste salt, waste oil and electromagnetic radiation from heat treatment production will pollute the environment. To solve the environmental pollution problem of heat treatment, the implementation of clean heat treatment (or green heat treatment) is one of the development directions of heat treatment technology.

       The above is the handling and maintenance method of the bearing, I hope it can be of some help to everyone. If you want to know more about groove ball bearings, roller bearings, you can continue to pay attention to our company's official website.
