Embodiment 1

[0011] The temperature of free forging is 1000°C. The blank after free forging is tested for flaw detection, and then the ring is rolled, and the temperature of the ring is 1105°C; then annealed, the annealing temperature is 500°C. Quenching and tempering are carried out. The quenching temperature is 840°C for bearing steel; 820°C for carburizing steel; and 170°C for tempering. After grinding and testing, it enters the assembly process.

Embodiment 2

[0013] The temperature of free forging is 900°C. The blank after free forging is inspected for flaw detection, and then the ring is rolled at 1050°C; then annealed at 400°C. Secondary cutting is carried out after sampling and testing, and then For quenching and tempering, the quenching temperature is 835°C for bearing steel; 810°C for carburizing steel; and 160°C for tempering. After grinding and testing, it enters the assembly process.

Embodiment 3

[0015] The temperature of free forging is 1150°C. The blank after free forging is inspected for flaw detection, and then the ring is rolled at 1280°C; then annealed at 600°C. After sampling and testing, secondary cutting is carried out, and then For quenching and tempering, the quenching temperature is 860°C for bearing steel; 840°C for carburizing steel; and 180°C for tempering. After grinding and testing, it enters the assembly process.

Abstract

The invention discloses a machining process of a bearing washer and particularly discloses a production and machining process of a bearing ring. According to the production and machining process of the bearing ring, the production period of a bearing can be shortened, the production cost of the bearing can be further lowered, meanwhile, the quality of the machined bearing ring can be further ensured, and it can be further ensured that the environment is not polluted. The machining process of the bearing washer comprises the steps of forming of bearing steel, material preparation, free forging,flaw detection, ring grinding, annealing, sampling for laboratory test, turning, heat treatment and grinding.

Description

technical field [0001] The invention relates to a processing technology of a bearing washer, in particular to a production and processing technology of a bearing ring. Background technique [0002] The process flow for producing bearing rings in the prior art is generally as follows: bearing steel → adding padding for 6-7 hours to the parison (surface temperature 1270°C, ingot temperature MSO°C) → slow cooling for 60 hours and then pickling and grinding out of the pit; de Heating (temperature 1120°C-1160°C) rolling H buffer 24 / J, then out of the pit, straightening, pickling and grinding → cutting into material sections → forging (roughening → punching ZH expansion zbe ring) → annealing → cutting → quenching →Tempering→Grinding: After passing all inspections, enter the assembly room. The disadvantages of the current production process are complex process, polluting the environment, long processing time of the bearing ring, and high manufacturing cost. Contents of the inven...
