Opening-nozzle saddle-shaped seam welding equipment

Abstract

The invention relates to opening-nozzle saddle-shaped seam welding equipment, which mainly comprises a cross-shaped automatic operation machine (1), a welding head track (2), a welding head (3) and a cylinder body workpiece (4). An axial moving device (11) of the cross-shaped automatic operation machine (1) is connected with a corresponding basic part; a vertical lifting arm (12) of the cross-shaped automatic operation machine (1) is assembled together with a transverse moving arm (13) by taking the axial moving device (11) as the base and is connected with the welding head track (2) through a suspension arm (17); and the welding head (3) is connected with the welding head track (2) through a locking mechanism (31) and can run along a ring-shaped track (21). The equipment achieves the function of multiple purposes, namely can perform gas cutting or plasma cutting on a saddle-shaped bevel pipe end and a pipe hole, and can perform high quality welding between the bevel pipe end and the pipe hole after an actuating mechanism is replaced; and in addition, the equipment has a compact and simple structure and is very suitable to be used on a construction site.

Description

Technical field [0001] The invention relates to a hole-opening and welding equipment, in particular to a hole-opening nozzle and saddle-shaped welding seam welding equipment. Background technique [0002] At present, there are two methods for cutting saddle-shaped bevel pipe holes and pipe heads for boilers, pressure vessels, steel pipes and other workpieces, and for butt welding of pressure vessels and steel pipes. First, the pressure vessel and the steel pipe are approximately processed first, and then the saddle-shaped bevel is obtained by hand grinding treatment, and then the two are manually welded together. This method is not repeatable, low in efficiency, labor-intensive and processing The quality is poor; the other is done by independent special equipment. Although the processing accuracy is high and the quality is good, the equipment used has the disadvantages of complex structure, numerous processing procedures, and high cost. Summary of the invention [0003] The purpo...

Problems solved by technology

One is to approximate the pressure vessel and the steel pipe first, then manually grind them to obtain a saddle-shaped bevel, and then weld the two together by hand. This method is not repeatable, inefficient, labor-intensive and expensive The quality is poor; the other is completed by independent special equipment. Although the processing precision is high and the quality is good, the equipment used has the disadvantages of complex structure, various processing procedures, and high cost.
