Automatic quenching oil groove and quenching method by utilizing automatic quenching oil groove

Abstract

The invention provides an automatic quenching oil groove and a quenching method by utilizing the automatic quenching oil groove. According to the technical scheme, the automatic quenching oil groove comprises a groove body, a liquid spraying mechanism and an oil liquid circulating mechanism are arranged inside the groove body, a stand is arranged inside the groove body, a material containing mechanism is arranged on the stand, and a hoisting mechanism drives the material containing mechanism to move up and down along the stand. Automatic quenching on a workpiece is achieved, the manpower operation is lowered, the dangerousness is lowered, the efficiency is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to an automatic quenching oil tank and a quenching method using the automatic quenching oil tank. Background technique [0002] Quenching—heating the steel to the austenitizing temperature and maintaining it for a certain period of time, and then cooling at a rate greater than the critical cooling rate to obtain a non-diffused transformation structure, such as martensite, bainite and austenite, etc. , is a process method to develop the internal potential of the workpiece. [0003] Quenching liquid circulation - when the workpiece is quenched, the heat of the workpiece itself is taken away by the quenching oil, the temperature of the quenching oil rises, and the circulation device circulates the hot oil to uniform the temperature of the quenching oil, and circulates the quenching oil to the cooling device for cooling In the device, the hot quenching oil is cooled down. [0004] At present, the most commonly used heat treatment an...

AI Technical Summary

Problems solved by technology

[0005] The above quenching method has the following characteristics: (1) The time required for the quenched workpiece to be quenched is too long, which often causes the temperature of the workpiece to drop a lot during the transfer process, even lower than the required quenching temperature, resulting in poor quenching effect and low quenching hardness. The hardened layer is shallow and cannot meet the quenching quality requirements; (2) After the feeder takes out the workpiece, the workpiece needs to be hoisted to the quenching oil tank for quenching by a crane. It is very dangerous to use the crane to hang the heated workpiece High, hooking the workpiece requires manual operation

Because the temperature of the heated workpiece is very high, it is necessary to manually hang the spreader on the material tray or the designated hooking position when lifting the workpiece. The operator has the risk of burns and burns, and long-term work also poses occupational hazards.
