A thin-walled steel pipe welding machine

Abstract

The invention relates to a thin-wall steel pipe welding machine, which comprises a feeding machine frame, wherein a power distribution control box is arranged in the feeding machine frame; a feeding mechanism is arranged on the feeding machine frame, and comprises a guide rail; a guide device and a welding device which are mutually matched are arranged on the guide rail; the guide device comprises two movable seats matched with the guide rail; in addition, a first guide plate and a second guide plate are respectively arranged on the two movable seats; an arc-shaped first coiling groove is formed in the first guide plate; an arc-shaped second coiling groove is formed in the second guide plate; in addition, the first coiling groove and the second coiling groove are mutually matched; the welding device is connected to the power distribution control box. The invention aims at providing the thin-wall steel pipe welding machine. The steel sheet is gradually coiled into the tubular shape through the multi-stage guide device; then, the opening position is welded through the welding device; the welding device does not need to move; the processing and the welding of a thin-wall steel pipe can be completed only through flatly moving the raw materials; the structure is simple; the operation is convenient; the material taking is convenient; the energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of steel pipe processing equipment, in particular to a thin-walled steel pipe welding machine. Background technique [0002] With the development of science and technology and the progress of society, steel pipes are used more and more widely, and the demand is increasing. Thin-walled steel pipes are also a kind of steel pipes. [0003] As we all know, steel pipes are generally formed by casting or stamping, and the length of steel pipes is limited by casting or stamping. Therefore, in practical applications, it is often necessary to butt steel pipes. The butt joint methods include threaded sockets and welding. Welding is mostly used, and welding is divided into manual welding and mechanical girth welding. Most of the production lines with large output use mechanical girth welding. Casting and mechanical girth welding are used to process thin-walled steel pipes. The structure is complex and the operation is cumbersome...

[0003] As we all know, steel pipes are generally formed by casting or stamping, and the length of steel pipes is limited by casting or stamping. Therefore, in practical applications, it is often necessary to butt steel pipes. The butt joint methods include threaded sockets and welding. Welding is mostly used, and welding is divided into manual welding and mechanical girth welding. Most of the production lines with large output use mechanical girth welding. Casting and mechanical girth welding are used to process thin-walled steel pipes. The structure is complex and the operation is cumbersome. The welding accuracy is not high, and the welding process needs to be rotated, resulting in complicated material removal and high energy consumption
