Electric control system of numerical-control plate shearing machine

Abstract

The invention discloses an electric control system of a numerical-control plate shearing machine, relating to the technical field of numerical-control plate shearing machines. The electric control system comprises a CPU module, an analog module and an HMI; a high-speed counting port of the CPU module is connected with a servo driver, the input end of a cutting-edge gap adjusting motor and the input end of a solenoid valve; the servo driver is connected with a servo motor; the servo motor is connected with a back stopper; the output end of the cutting-edge gap adjusting motor is connected with the input end of a linear displacement sensor; the output end of the linear displacement sensor is connected with the analog module; the output end of the solenoid valve is connected with the input end of a stay wire rotating potentiometer; and the output end of the stay wire rotating potentiometer is connected with the analog module. The electric control system can accurately control the back stopper, the cutting-edge gap, the cutting-edge shear angle and the shearing stroke of the numerical-control plate shearing machine, intelligent control is realized by combining the HMI technology, and the electric control system also has the advantages of being easy to operate and maintain and proper in the price.

Description

technical field [0001] The invention relates to the technical field of numerical control shearing machines, in particular to an electrical control of numerical control shearing machines capable of realizing the precise positioning functions of backgauge, cutting edge clearance, cutting edge shearing angle and shear distance of the numerical control shearing machine system. Background technique [0002] With the maturity of our country's basic industry, the demand for domestic CNC shearing machines is growing rapidly. At present, most of the domestic CNC shearing machine control systems are manufactured by DELEM of the Netherlands, CYBELEC of Switzerland and some other foreign companies. The CNC shears provided by these manufacturers The plate machine is expensive, has a long supply cycle and a long maintenance cycle, and cannot meet the requirements of some domestic users who need special processing technology.

[0002] With the maturity of our country's basic industry, the demand for domestic CNC shearing machines is growing rapidly. At present, most of the domestic CNC shearing machine control systems are manufactured by DELEM of the Netherlands, CYBELEC of Switzerland and some other foreign companies. The CNC shears provided by these manufacturers The plate machine is expensive, has a long supply cycle and a long maintenance cycle, and cannot meet the requirements of some domestic users who need special processing technology. It only has the function of controlling a single back gauge, gap, shear angle and shear distance, and does not have the ability to control other The scalability of functions has been unable to meet the diversity characteristics of my country's sheet metal processing industry. Therefore, in order to break this technical barrier, our company has developed a CNC shearing machine control system based on a domestic PLC platform, realizing the CNC shearing machine.
