Steel bar submerged arc stud welding gun

Abstract

The invention belongs to the technical field of welding, and in particular relates to a steel bar submerged arc stud welding torch. The slider is fixed on the bracket; the support plate A fixes the double-axis cylinder and is installed on the slider; an insulating block A is set between the slider and the support plate A, and an insulating block B is set between the support plate A and the double-axis cylinder The cylinder block of the biaxial cylinder is fixed on the support plate A, the support plate B is fixed on the moving shaft of the biaxial cylinder, and the support plate B drives the steel bars to complete the welding sequence action; the relative sliding between the support plate A and the support plate B can be done, The lifting block controls the lifting height of the support plate A; the adjustment screw is set on the lifting block; the lower part of the support plate B is provided with a locking device, a knob, a steel bar stopper, and a steel bar support, and the steel bar support is fixed on the support plate B. The tightening device and the steel bar block form a back-shaped structure to fix the steel bar, and the clamping force on the steel bar is adjusted by rotating the knob. The operation of the invention is simple and reliable, and the welding efficiency of submerged arc stud welding of steel bars is improved.

Description

technical field [0001] The invention belongs to the technical field of welding, and in particular relates to a steel bar submerged arc stud welding torch. Background technique [0002] T-shaped welds of steel bars are generally welded by manual arc welding. Most of them are T-shaped fillet welds, and some of them use perforated plug welding. The welding quality and welding efficiency are low, especially perforated plug welding, and the workload of weld assembly and processing is relatively large. Stud welding is a welding method with high welding efficiency, and can realize full-section welding, so as to achieve equal strength connection. At present, domestic stud welding can only weld standard studs, and some welding torches that can weld steel bars are only suitable for straight steel bars. The steel bar is clamped at the end of the welding torch, and the welding torch is held in hand for welding. The welding torch has poor adaptability to the shape of the steel bar and i...

Problems solved by technology

At present, domestic stud welding can only weld standard studs, and some welding torches that can weld steel bars are only suitable for straight steel bars. The steel bar is clamped at the end of the welding torch, and the welding torch is held in hand for welding. The welding torch has poor adaptability to the shape of the steel bar and improves the strength of the steel bar The weight is small, the stability is poor during welding, the quality is difficult to guarantee, and the labor intensity of the operator is high
