Abstract

The invention relates to a steel tube butt welding machine. The butt welding machine comprises a rack, and a main shaft which is driven by a drive unit to rotate at intervals and is arranged vertically is in rotary connection onto the rack. A rotary disc is arranged at the top of the main shaft, at least three rotary shafts distributed circularly at intervals are in rotary connection onto the rotary disc, and drive motors for driving the rotary shafts to rotate respectively are further installed on the rotary disc. Lower steel tube clamps are arranged at the tops of the rotary shafts, supporting frames corresponding to the rotary shafts are further arranged on the rotary disc, and upper location air cylinders are arranged on the supporting frames. Upper steel tube clamps are mounted on downward stretching piston rods of the upper location air cylinders. A welder and a welding gun fixing seat are arranged on the rack, and a welding gun of the welder is in rotary connection onto the welding gun fixing seat which is in sliding connection onto the rack and is driven by a drive air cylinder. By means of the butt welding machine, clamping processes of product can be simplified, the welding efficiency and the welding quality are improved, the weld appearance quality of product produced through the butt welding machine is good, the labor intensity of workers is greatly reduced, and the product welding time is shortened.

Description

technical field [0001] The invention belongs to the field of welding equipment, in particular to a steel pipe butt welding machine used for butt welding of steel pipes. Background technique [0002] As we all know, there are two main production processes for butt welding of steel pipe fittings. One is manual argon arc welding, which is characterized by low efficiency, uneven welding, and low pass rate. It is usually used for sample production or small batches of new products. production; another method is to adopt a horizontal girth welding machine for welding, such as a kind of equipment that can automatically weld a girth seam disclosed in Chinese invention patent ZL200920027186.4, which includes a workpiece fixing device and a welding torch device; wherein the workpiece fixing device includes equipment Bench, speed regulating motor, reducer, workpiece fixed mold, horizontal cylinder, horizontal cylinder fixing plate, longitudinal cylinder connecting rod, guide sleeve, lon...
