Embodiment Construction

[0017] Example: see Figures 1 to 3 As shown, the heat treatment and quenching equipment for small and medium-sized bearing rings includes an oil tank 1, and a driving sprocket 2 and a driven sprocket 3 are arranged in the oil tank 1. The driving sprocket 2 and the rotating shaft of the motor 4 are fixed together, and the motor 4 is placed in The lower part of the oil tank 1, the chain 5 is tensioned on the driving sprocket 2 and the driven sprocket 3, and the guide rail 6 is fixed in the oil tank 1;

[0018] Each heat treatment device 7 is composed of a connecting plate 71, two roller shafts 72, two rollers 73 and two high-temperature-resistant bearings 74. The connecting plate 71 is welded and fixed on the chain 5, and the connecting plate 71 is welded and fixed with a high-temperature-resistant bearing 74. The outer ring of the high temperature resistant bearing 74 is welded and fixed with a roller shaft 72, the other end of the roller shaft 72 is fixed with a roller 73, an...

Abstract

The invention discloses heat treatment quenching equipment for small and medium-sized bearing rings. A driving chain wheel and a driven chain wheel are arranged in an oil groove; the driving chain wheel is fixed with a rotating shaft of a motor; the motor is positioned at the lower part of the oil groove; a chain is tensioned on the driving chain wheel and the driven chain wheel; a guide rail is fixed in the oil groove; each of heat treatment devices is composed of a connecting plate, two roll shafts, two rollers and two high temperature-resistant bearings; the connecting plates are welded and fixed on the chain; outer rings of the high temperature-resistant bearings are welded and fixed on the connecting plates; the roll shafts are welded and fixed on inner rings of the high temperature-resistant bearings; the rollers are fixed at the other ends of the roll shafts, and are positioned on the guide rail; stop edges are formed on each of the roll shafts; the stop edges of the adjacent two roll shafts are leant to each other; workpieces are positioned on the adjacent two roll shafts; and the plurality of heat treatment devices are connected to the chain. The heat treatment quenching equipment prevents the problems of high manual workload and workpiece damage proneness in a traditional quenching method, improves the production efficiency, and enhances the quality of the bearing rings after the bearing rings are quenched.

Description

Technical field: [0001] The invention relates to the technical field of production of bearing rings, in particular to equipment used for heat treatment and quenching of small and medium-sized bearings. Background technique: [0002] CN201183812Y discloses a heat treatment and quenching machine for small and medium-sized bearing rings. Compared with traditional heat treatment and quenching methods, it reduces labor intensity, improves production efficiency, and significantly improves the pass rate of bearing rings after quenching. Its disadvantages are: 1. The number of bearing rings processed per unit time is limited, and the production efficiency needs to be further improved. 2. When quenching in the oil tank, the vibration of the bearing ring workpiece is not enough, which is not conducive to improving the quality of the bearing ring after quenching. Invention content: [0003] The purpose of the present invention is to provide a kind of heat treatment and quenching equ...
