Description

Automatic plasma welding machine

technical field

The utility model relates to a plasma welding machine, in particular to an automatic plasma welding machine which can realize automatic feeding, automatic positioning, automatic clamping and automatic welding.

Background technique

The formation of high-quality glass products has a lot to do with the action of hot glass and molds. Therefore, in the glass mold manufacturing industry, the choice of mold materials is very important. The dominance of cast iron as a material for making glass forming molds has not changed, and the mechanical strength, wear resistance, and oxidation resistance of glass molds have always attracted attention. For the glass mold manufacturing industry, in order to enhance the mechanical strength, wear resistance and oxidation resistance of the glass mold, it is often necessary to use nickel-based powder to weld the glass mold.

For the welding of glass molds, the traditional welding is manual welding, which has low welding efficiency, and the welding process of each worker is different, so it is difficult to guarantee the quality. The amount of nickel-based powder used in the manual welding process is also difficult to grasp, and expensive nickel-based powder is often wasted. Moreover, manual welding often leaves air holes on the surface of the glass mold, and the powder is easy to fall off after welding.

At present, most of the key wear-resistant parts of glass molds are welded to designated parts by plasma welding machines. With years of hard work by the scientific and technical personnel of the welding institute, the main circuit and control circuit of the welding machine have been continuously improved and perfected, and the performance has been greatly improved. The centering accuracy of the welding torch, the production of the plasma arc and the cooling conditions of the nozzle have all been improved A great improvement has been made, and the automation of welding has been realized. Compared with similar foreign welding machines, my country's plasma welding machines have reached the level of similar international products. The key wear-resistant parts of bottle glass molds of most manufacturers are welded by plasma welding machines. The welding surface is required to be flat and smooth without oxidation, which solves the welding process problem that does not need to be polished after welding.

However, the current domestic plasma welding machines basically use manual loading and unloading, resulting in low equipment efficiency, low welding accuracy, high labor intensity, and heat damage. Therefore, the popularization, application and development of domestic plasma welding machines require new breakthroughs, and the realization of automatic operation of equipment is the need of industrial development and the need of high-efficiency and high-quality product production.
