Electrical control device of vertical jet quenching machine tool

Abstract

The invention relates to an electrical control device of a vertical jet quenching machine tool. The electrical control device comprises an upper computer, a control master station and multiple collection substations, wherein the upper computer is connected with the control master station, and the control master station is connected with each collection substation; the upper computer comprises a setting unit, the collection substations are distributed around the vertical jet quenching machine tool and connected with actuators of the vertical jet quenching machine tool respectively, and each actuator of the vertical jet quenching machine tool comprises a coder and a displacement sensor. By the aid of the electrical control device, water jet reducing and spray reducing can be controlled accurately, and quenching quality of heat treatment workpieces is guaranteed.

Description

technical field [0001] The invention relates to an electric control device, in particular to an electric control device for a vertical spray quenching machine tool. Background technique [0002] At present, the control system of the vertical spray quenching machine tool is a control device for heat treatment of the workpiece in the split heat treatment furnace. During the treatment process, the workpiece is sprayed with water, spray quenched and cooled according to different requirements, and the physical characteristics of the metal medium are adjusted. Heat treatment of large workpieces plays an important role. [0003] Among them, the maximum diameter and length of the workpiece in the split heat treatment furnace is not less than 20 meters. The control of the quenching process is directly related to the quality control of the heat treated workpiece and the further development of heat treatment. It affects the quality of the entire workpiece, so heat treatment is an impo...

Problems solved by technology

[0004] At present, when the domestic open-close heat treatment furnace is quenched, the control of the water spray diameter is not very precise. The same workpiece has the same process settings, but the position of the water spray diameter is different, so it will largely Affect the quenching quality of the workpiece, and ultimately lead to the quality of the heat treatment workpiece cannot be guaranteed

Specifically, the traditional control system lacks stability in operation, has a high failure rate, and has poor flexibility. The most important thing is that the control of the variable diameter of the water spray is inaccurate, which leads to the inability to guarantee the quality of the quenched workpiece, and ultimately leads to a substantial increase in production costs.
