Automatic welding supporting device of 60-degee major-diameter thick-wall tapered circumferential seams

Abstract

The invention discloses an automatic welding supporting device of 60-degee major-diameter thick-wall tapered circumferential seams, which has lower manufacture cost and comprises a fixed bottom plate, wherein the fixed bottom plate is respectively fixedly provided with a pair of front supporting upright posts and a pair of rear supporting upright posts, the pair of front supporting upright posts are respectively fixedly provided with a driven wheel supporting seat, driven wheels are rotatably arranged in the driven wheel supporting seats through driven shafts, the pair of rear supporting upright posts are respectively fixedly provided with a drive wheel supporting seat, drive wheels are rotatably arranged in the drive wheel supporting seats through drive shafts, the drive shafts are connected with drive motors fixedly arranged on the drive wheel supporting seats, the middle part of the rear end of the fixed bottom plate is fixedly provided with a catch wheel supporting seat, and a catch wheel is rotatably arranged in the catch wheel supporting seat through a catch wheel shaft. The automatic welding supporting device of the 60-degee major-diameter thick-wall tapered circumferential seams has the advantages of lower manufacture cost, simple and practical structure and higher production efficiency, and is suitable for massive and continuous production.

Description

technical field [0001] The invention relates to an automatic welding support device for a cone circular seam, in particular to a 60-degree large-diameter thick-walled cone automatic welding support device for a circular seam. Background technique [0002] The 60-degree large-diameter thick-walled cone is a common part in chemical equipment. Generally speaking, the 60-degree large-diameter thick-walled cone with a large end diameter greater than 2600mm has a girth weld in the middle. For a 60-degree large-diameter thick-walled cone with a girth weld in the middle, to realize the automatic welding of the middle girth, the first condition is to ensure that the angle α between the welding busbar and the horizontal plane is not greater than 15 degrees, generally within 10 degrees, to ensure The small angle between the welding bus bar and the horizontal plane is beneficial to the forming of the welded joint. Secondly, during automatic welding, it is necessary to ensure that the ro...

Problems solved by technology

At present, large-scale displacers are generally used to realize the automatic welding of the middle circular seam of the 60-degree large-diameter thick-walled cone, but for general chemical equipment manufacturers, the automatic welding of the circular seam of the 60-degree large-diameter thick-walled cone is not enough Very large, too expensive to invest in a large shifter
