Abstract

The invention discloses a spray quenching device for cold roll machining and a using method, and belongs to the technical field of spray quenching. The spray quenching device for cold roll machining comprises a lifting pore plate, a spray cylinder barrel, a rotating pore plate, a driving pore plate and a spray nozzle. The two ends of the lifting pore plate are fixedly connected with lifting columns, so that the lifting columns move to drive the driving pore plate through the rotating pore plate to rotate around the center axis of the spray cylinder barrel, and the inner wall of the driving pore plate is slidably connected with a guide column connected with the spray nozzle. According to the spray quenching device for cold roll machining and the using method, through arrangement of a swing sleeve, in a transferring mechanism, a rotating disc rotates to drive a lifting pore column through a rotating guide column to slide, the lifting pore column moves to drive a connecting guide rod to move, the connecting guide rod moves to drive a swing bent plate through a swing pore groove to swing, the swing bent plate swings to drive the swing sleeve through a telescopic swing plate to rotate, and transferring operation of a cold roll is achieved.

Description

technical field [0001] The invention relates to the technical field of spray quenching, in particular to a spray quenching device for cold roll processing and a use method thereof. Background technique [0002] The cold roll is a complex component with a very hard surface and bears a lot of stress. Therefore, the cold roll requires high manufacturing quality, which is a necessary condition to ensure the use effect. In order to improve the manufacturing quality of the cold roll, it is necessary to The cold roll is subjected to quenching operation. Quenching is to heat the steel above the critical temperature, hold it for a certain period of time, and then cool it at a rate greater than the critical cooling rate, so as to obtain an unbalanced structure mainly composed of martensite. Quenching is a heat treatment process. The most widely used process method in steel heat treatment process. [0003] After searching, the patent of Chinese application publication number CN1108630...
