Automatic straight tube butt-welding machine applied to boilers

Abstract

The invention discloses an automatic straight tube butt-welding machine applied to boilers. The automatic straight tube butt-welding machine comprises a welding main machine and an operation platform, wherein the welding main machine is fixed on the operation platform; a wire unwinding mechanism is arranged at the top end of the welding main machine; a vertical moving mechanism and a transverse moving mechanism are arranged on the front side of the welding main machine; the transverse moving mechanism is slidably arranged on the vertical moving mechanism; a welding main body is arranged on the transverse moving mechanism; two automatic rotation clamps are oppositely arranged on the operation platform; a parallelism correcting mechanism is arranged in the operation platform and is located at a middle position between the two automatic rotation clamps. Through the straight tube butt-welding machine, the problems of low sealing performance, poor appearance, low quality and inconvenience output of welding seams are solved; the straight tube butt-welding machine has the advantages of high welding parallelism, high sealing performance and stable output of the welding seams; the welding quality is improved.

Description

technical field [0001] The invention relates to an automatic straight pipe butt welding machine for boilers. Background technique [0002] In the boiler field, more tubes are needed, such as superheaters and reheaters, etc. A large number of coiled tubes are required in superheaters and reheaters, and these coiled tubes need to be welded with multiple straight tubes before coiling. After completion, the straight pipe is bent into a coiled shape by the bending mechanism, and then used, but there are some problems in the existing straight pipe welding: [0003] First of all, the flux used in straight pipe welding is used for welding, and the sealing of the welded seam during the use of the welded straight pipe is not high enough, the appearance of the weld is poor, and the quality is not high; [0004] Secondly, in straight pipe welding, two integrated automatic rotating fixtures are generally used for clamping and rotating. The welding seam of the pipe is located in the midd...
