Plasma cutting machine, plasma cutting machine pressure regulating device and pressure regulating method

Abstract

The invention belongs to the technical field of cutting devices and pressure regulating methods, and in particular, relates to a plasma cutting machine, a plasma cutting machine pressure regulating device and a pressure regulating method. The plasma cutting machine comprises a bottom frame; the top of the bottom frame is fixedly connected with a cutting plate through bolts. According to the plasmacutting machine, the plasma cutting machine pressure regulating device and the pressure regulating method, accessories and a system are combined for use, a groove can be formed in the bottom of a pressure regulating shell; the groove is in contact with the cross rod; the shaft rod carrying a roller is in sliding connection with the outer wall of a cross rod so as to cooperate with movement of a cutting head, the flexibility is high, and the operation range of the cutting plate is large; a variable frequency controller is combined in the pressure regulating shell and can be matched with a control frame to be connected with the pressure regulating module, after the pressure regulating module is electrically connected with a processing module and a control module, the pressure regulating module is used for carrying out pressure regulating control operation, the purposes of detection, comparison, transmission and control are achieved, and the controllability of the pressure regulating module on the pressure regulating device is guaranteed.

Description

technical field [0001] The invention relates to the technical field of a cutting device and a voltage regulating method, in particular to a plasma cutting machine, a plasma cutting machine voltage regulating device and a voltage regulating method. Background technique [0002] Cutting is a kind of physical action, and cutting in a narrow sense refers to cutting objects with sharp tools such as knives. Cutting objects with low hardness such as food and wood; cutting in a broad sense refers to using tools, such as machine tools, flames, etc. to break objects under pressure or high temperature. [0003] With the development of the modern mechanical processing industry, the requirements for cutting quality and precision are constantly improving, and the requirements for improving production efficiency, reducing production costs, and highly intelligent automatic cutting functions are also increasing. Cutting machines are divided into flame cutting machines. , plasma cutting mach...
