Bevel cutting device of plasma cutting machine

Abstract

The invention discloses a bevel cutting device of a plasma cutting machine. The bevel cutting device comprises a gun body clamping linkage mechanism, a transverse rotating mechanism and a longitudinal rotating mechanism, wherein a bent rod of the gun body clamping linkage mechanism is hinged with a reciprocating shaft of the longitudinal rotating mechanism, the gun body clamping linkage mechanism is fixed with a rotating shaft of the transverse rotating mechanism through a fixing bottom plate and a fixing seat, and the rotating shaft is respectively connected with a fixing sleeve and a nut seat of the longitudinal rotating mechanism. The bevel cutting device of the plasma cutting machine has the advantages of stability and reliability, simple structure, light weight and good rigidity, and the cutting accuracy, surface machining quality and production efficiency are greatly improved.

Description

technical field [0001] The invention relates to the technical field of plasma composite processing, in particular to a bevel cutting device for a plasma cutting machine. Background technique [0002] In recent years, the development of CNC plasma cutting machines in China is obvious to all, but the development of CNC plasma sheet bevel cutting is still relatively slow, especially compared with foreign counterparts, there is still a big gap. my country's CNC plasma sheet bevel cutting equipment is far behind developed countries in terms of function, quality and efficiency. [0003] For a long time, the processing of plate grooves in my country has been completed by machining and gouging, or by CNC plasma linear cutting and blanking, and then secondary processing of the grooves with other equipment, which has seriously affected the production efficiency and progress of enterprises, and cannot adapt Modern fast-paced and efficient bevel cutting requirements. [0004] At presen...

Problems solved by technology

[0003] For a long time, the processing of plate grooves in my country has been completed by mechanical processing and gouging, or by CNC plasma linear cutting and blanking, and then secondary processing of the grooves with other equipment, which has seriously affected the production efficiency and progress of enterprises, and cannot adapt Modern fast-paced and efficient bevel cutting requirements

[0004] At present, in terms of plasma bevel cutting, only a few multinational companies have mature beveling technology, and they have adopted a strategy of high price and high profit to restrict the domestic plasma bevel cutting market; among the bevel cutting devices developed and produced by domestic manufacturers , the ubiquitous structure is huge, its own quality is too heavy, or the structure is too complex, the rigidity is poor, the assembly accuracy cannot meet the requirements, and the cutting speed and quality cannot be guaranteed.

It can be said that the current domestic plasma bevel cutting devices are still unable to meet the user's requirements for high-quality, high-efficiency, and high-precision bevel cutting
