Problems solved by technology

[0002] At present, the heat treatment, quenching and tempering of large bearing rings in China is to place a single workpiece on the tooling, heat it to a certain temperature in the furnace, and then put it in the quenching medium for quenching. Only one piece can be produced each time. Products, and the tooling must be heated and cooled together with the workpiece every time. Generally, the life of the tooling is only 2-3 months. This method not only wastes time, manpower and material resources, but also consumes a lot of tooling

Embodiment Construction

[0011] The present invention is specifically described below in conjunction with accompanying drawing:

[0012] Put the support 5 in one leg of the three-leg hoisting frame 1, then place the pressure pad 6 under one leg of the three-leg hoisting frame 1, and connect the support 5 and the pressure pad 6 together with the stud bolts 2 , and then put the tie rod 3 into the support 5 from bottom to top, weld the pad 4 and the tie rod 3 together to prevent the pull rod 3 from sliding down, insert the pin 7 into the tie rod 3, and you can clearly see the quenching position of the workpiece on the quenching tank , to prevent the workpiece from tilting. Install the other two legs of the three-leg sling in sequence as above. In this way, the distance of the slideway can be adjusted according to the size of the workpiece. The workpiece 8 can be hoisted and quenched easily in this way, so that the processing quality and efficiency are greatly improved (such as figure 1 shown).

Abstract

The invention relates to a large-scale dimension-adjustable bearing heat treatment tool and belongs to the field of bearing tempering and quenching technologies. The novel dimension-adjustable bearing heat treatment tool provided by the invention can be used to raise utilization rate of a heating furnace by more than 4 times and reduce the temperature of a quenching medium by more than 40%. A product obtained after quenching has uniform hardness and good surface quality. In addition, quenching time is saved and consumption of a quenching tool is saved as well.
