Abstract

The invention discloses a numerical-control plasma power source with multiple plasma cutting torches. The plasma power source is connected with a main DSP (digital signal processor) digital signal controller, the main DSP digital signal controller is further connected with input ends of multiple sub DSP signal controllers through control lines, each sub DSP digital signal controller is connected with one plasma cutting torch through at least two inverter modules, and each inverter module is connected with a CAN (controller area network) bus. According to the technical scheme, the numerical-control plasma power source adopts simple principles, one plasma power source can be distributed to multiple plasma cutting torches so as to facilitate constant-current power output control, and accordingly, the multiple plasma cutting torches can be subjected to completely synchronous arc striking and complicated cutting of grooves can be completed at one step. In addition, the numerical-control plasma power source with the multiple plasma cutting torches has the advantages of high cutting precision and capability of improving operation efficiency and saving resources.

Description

technical field

[0001] The invention relates to a plasma power supply on a plasma cutting machine, in particular to a numerically controlled plasma power supply with multiple plasma cutting torches. Background technique

[0002] Plasma cutting power supply is the key equipment for providing and controlling energy in the plasma cutting process, and its performance plays a vital role in the reliability of plasma arc generation, cutting quality and production efficiency. With the rapid development of computer and digital control technology, CNC plasma cutting technology is widely used in industrial production, and it is outstanding in improving processing accuracy, saving materials, and improving labor productivity. At present, the use of plasma cutting in my country's metal processing industry is to "decompose" or ionize some gases through a high-frequency arc to make a mixed gas (it can be air, or a mixture of hydrogen, argon and nitrogen) into basic atomic particles. , resul...
