Description

Butt welding tool for automobile pipe fittings

technical field

Background technique

In auto parts accessories, many accessories are pipe fittings for connection, control, direction change, diversion, sealing, support, etc. Therefore, we refer to the pipe fittings used in auto parts as auto pipe fittings. According to different processing technology, automobile pipe fittings are divided into butt welding pipe fittings (there are two types of welded seam and no weld), socket welding and threaded pipe fittings, and flange pipe fittings.

One of the butt-welded automobile pipe fittings is the butt welding of the nozzle to the nozzle. When two pipe fittings are welded, it is usually through the simple cooperation of the workers. Because the interior of the pipe fittings is hollow, it is difficult to find the axis, and welding requires two pipes. The fittings should be as centered as possible, that is, the central axes of the two pipe fittings are coincident, and it is difficult to use ordinary fixtures to effectively fasten and fix them. Therefore, the pipe fittings can only be welded by hand, especially for two pipe fittings with different diameters. During welding, it is very difficult to align the center, resulting in unsightly or even unqualified automotive pipe fittings after welding. It needs to be cut and then welded again, resulting in low production efficiency, and it is difficult for personnel to hold the pipe fittings, which is easy to hold for a long time during welding. The fatigue caused by the hand-held instability makes the pipe fittings have deviations during welding, and the welding precision is low, which affects the qualified rate of the automobile pipe fittings.
