A CNC short arc cutting machine tool

Abstract

The invention discloses a numerically-controlled short-arc cutting machine tool. The machine tool comprises a tool body, a short-arc power supply, an anode device, a cathode device, a water and gas system and a tailstock, wherein the anode device and the tailstock are installed at head and tail ends of the tool body respectively, the anode device is located on one side of the tool body, the water and gas system is installed on the cathode device, the anode device is connected with the short-arc power supply through an anode cable, and the cathode device is connected with the short-arc power supply through a cathode cable; the machine tool further comprises a numerical control system, the numerical control system is connected with the short-arc power supply through an intermediate relay, and the anode device, the cathode device, the water and gas system and the tailstock are electrically connected with the numerical control system. According to the machine tool, the numerical control system is additionally arranged and reasonably connected with the short-arc power supply through the intermediate relay, and the anode device, the cathode device, the water and gas system and the tailstock are electrically connected with the numerical control system, so that numerical control on all structures of the numerically-controlled machine tool is realized, the application range is wide, and the machining precision is high.

Description

technical field [0001] The invention relates to the field of short arc machining equipment, in particular to a numerically controlled short arc cutting machine tool. Background technique [0002] Short-arc cutting machine tools make the processing methods of the machining industry more diversified, and have a positive role in promoting the development of the machinery industry. They are widely used. The technology disclosed in the Chinese patent "power supply device for cutting equipment" has achieved excellent results, but the short arc cutting machine tool used in the prior art also has the following shortcomings: [0003] 1. When in use, only standard cylindrical surface processing or cutting processing can be performed, and the rest of the shape processing can only be performed by manual control, which has great limitations, and the processing accuracy is not high, which greatly limits the overall processing ; [0004] 2. In terms of water recycling, it can only rely o...

AI Technical Summary

Problems solved by technology

[0003] 1. When in use, only standard cylindrical surface processing or cutting processing can be performed, and the rest of the shape processing can only be performed by manual control, which has great limitations, and the processing accuracy is not high, which greatly limits the overall processing ;

[0004] 2. In terms of water recycling, it can only rely on natural precipitation, and the accumulated residue can only be removed manually after a period of time. This not only increases the labor load of workers, but also the efficiency and cleanliness of natural sedimentation are too low. not convenient;

[0005] 3. The tailstock device of the original machine tool is manually controlled for moving and jacking functions, so that the operation must be performed manually, and the jacking position must be observed at the same time, which is inconvenient and not smooth to use. , it is impossible to predict, and it is not known whether the tightness is sufficient, which has a great impact on the life of the workpiece and the machine tool;

[0006] 4. There is no relevant parameter monitoring in the process of processing, such as: current, voltage, water pressure, air pressure, water temperature, etc. can only be carried out with the experience of the operator, and the requirements for the operator are too strict
