Plasma arc welding machine for metal can production

Abstract

The invention discloses a plasma arc welding machine for metal can production, and relates to the technical field of plasma arc welding machines, the plasma arc welding machine comprises a fixing frame, a fixing seat and a plasma arc welding head, rotating rollers are arranged on the two sides of the interior of the fixing frame, and a first suction cup assembly is arranged on the outer side of the rear portion of the fixing frame; and a displacement assembly is connected to the middle end of the inner side of the fixing frame and comprises a connecting base, a displacement base and rolling wheels, the displacement base is arranged on the outer side of the bottom of the connecting base, the rolling wheels are connected to the outer side of the bottom of the displacement base, and a second suction cup assembly is arranged at the outer end of the connecting base. Displacement extension is carried out on the fixing frame and the displacement base, a displacement sliding rail matched with the size of a tank does not need to be specially manufactured according to the size of the tank in the welding process of equipment, and the equipment can be used only by aligning the equipment with the joining seam, so that the welding convenience of the equipment can be improved, and the welding efficiency is improved. And meanwhile, the tank bodies with different lengths can be welded by the equipment, so that the use flexibility of the equipment can be improved.

Description

technical field [0001] The invention relates to the technical field of plasma arc welding machines, in particular to a plasma arc welding machine used in the production of metal cans. Background technique [0002] Plasma arc welding machine refers to a welding machine that uses high energy density beam of plasma arc as welding heat source. Plasma arc welding has energy concentration, high productivity, fast welding speed, small stress and deformation, stable electric arc and is suitable for welding thin plates and boxes, etc. Features, especially suitable for the welding of various refractory, easily oxidized and heat-sensitive metal materials (such as tungsten, molybdenum, copper, nickel, titanium, etc.). The principle of the plasma arc welding machine is that the gas is dissociated by arc heating. It is compressed when passing through the water-cooled nozzle at high speed, increasing the energy density and degree of dissociation, and forming a plasma arc. Its stability, ca...

AI Technical Summary

Problems solved by technology

[0003] When common plasma arc welding machines on the market weld metal cans, it is usually necessary to install auxiliary slide rails on the surface of the metal cans for auxiliary support to ensure the stable operation of the plasma arc welding machine. However, there are many types of metal cans, which leads to The radian is more changeable, which makes the ion arc welding machine need to adapt the corresponding auxiliary slide rail according to the type of tank body, which makes the use of the ion arc welding machine not convenient enough
