Plasma arc plane surface welding machine

Abstract

The invention discloses a plasma arc plane surface welding machine, and aims to provide plasma arc plane surface welding equipment for a plane-shaped composite material surface welding product. The plasma arc plane surface welding machine comprises a machine frame and a welding platform, wherein the machine frame is in a portal frame structure, the welding platform is correspondingly arranged, and the machine frame and the welding platform can relatively longitudinally move in parallel under the drive of a longitudinal travelling motor; a transverse sliding plate which is driven by a transverse mobile motor and can transversely move or swing is arranged at the side of a crossbeam of the machine frame, a liftable welding torch bracket is arranged at the outer side of the transverse sliding plate, a plasma welding torch pointing to the welding platform is installed on the welding torch bracket, the height position of the plasma welding torch can be adjusted under the drive of a lifting motor, and the plasma welding torch is also provided with a direct current welding power supply, a working gas and a cooling water source; and leads for connecting all motors are led to a control box and automatic control is realized through an electric automatic control system. The plasma arc plane surface welding machine has reasonable structural design and mature and reliable technology, satisfies each operational requirement for welding working, and realizes high-efficiency automatic production.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and in particular relates to a plasma arc plane surfacing welding machine. Background technique [0002] "Welding" magazine, No. 2, 1999, pages 5 to 8, pointed out in the article "High-quality and high-wear-resistance surfacing technology" that composite materials use plasma arc surfacing technology to obtain a composite surfacing layer with high wear resistance. It is an important development of plasma arc surfacing application technology. The quality of the composite surfacing layer obtained by plasma arc surfacing technology is stable and reliable. Under severe wear conditions, the wear resistance of the composite surfacing layer is particularly prominent. Since the surfacing layer is metallurgically combined with the surface of the protected workpiece, Therefore, it has high bonding strength and can meet certain impact resistance requirements. [0003] In recent years, in-depth re...

Problems solved by technology

However, the development of some aspects of process equipment for composite material plasma arc surfacing is relatively lagging behind, such as welding equipment for large-area planar surfacing products. At present, there is no mature and reliable plasma arc surface surfacing machine for use. Production, surface surfacing products are still mainly produced by hand, not only the welding quality is difficult to guarantee, but also the production efficiency is low, and the labor intensity of the operators is high
