Deep groove ball bearing processing steps

In order to make deep groove ball bearings can get better performance, general process procedures are conducted by manufacturers, such not only can let the deep groove ball bearing is increased in quality, also can improve the aesthetic of the bearing and reduce friction. China bearing network for everybody to more comprehensive understanding of deep groove ball bearing grinding process, the author made the detailed introduction. Deep groove ball bearing processing steps: 1, the tube billet processing: bearing steel in the furnace heated to 1150 ℃ ~ 1200 ℃, use the punching machine for heating tube billet after perforation, made capillary; 2, spheroidizing annealing: the capillary for spheroidizing annealing, capillary after annealing hardness in the range of HRB88 ~ 94; 3, the tube billet hot-rolling: after annealing capillary into the furnace of secondary soaking; Will go through a second capillary after soaking by reducing, reducing wall, extending rolling forming tubes; , plastic tube billet cutting: 4 tubes through the sizing and sizing plastic, then cutting, straightening form suite; 5, recrystallization annealing: suite to recrystallization annealing treatment, eliminate the strain hardening, so as to facilitate implementation of cold rolling; 6, soft grinding suite: soft grinding first suite of double end face, and then soft grinding cylindrical suite, first double end face grinding, cylindrical grinding, cylindrical is through grinding, between material and material through the transverse joint together to carry on the processing, ensure parts outside diameter surface and plate in the same plane, guarantee the diameter taper under control, adjustment of double end face grinding of the Angle between the grinding wheel, control end face parallel to the poor, after the end surface accuracy as the machining datum; Cylindrical use centerless grinding; 7, suite hole: retaining bolt holes on the surface of the suite and oil hole, coarse suite inner hole surface, in preparation for the inner hole surface of cold rolling. Suite: 8, cold rolling for deep groove ball bearing ring channel, cold rolling process of cold rolling core roller feeding speed has six phase speed, speed range is 0. 4毫米/秒~ 1。 0 mm/s, a processing cycle track speed curve is fast, slow, slow, and eventually stop; Rolling time between 6 s ~ 14 s, rolling pressure is 80 kn; 9, turning suite: suite for chamfering, seal groove; 10 and fine suite: fine grinding suite, enhance the surface precision of suite; 11, install bearing: between the ring into the ball, the bracket will be installed, injecting grease, install the seals, deep groove ball bearing assembly. 【 Warm prompt. 【 The bearing network] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent our views to its approval or responsibility for their authenticity.
