Embodiment Construction

[0011] The present invention is described in further detail below in conjunction with embodiment.

[0012] See figure 1 and figure 2 , a boiler inner ring seam submerged arc automatic welding machine is mainly composed of a welding trolley, a welding power source 18, an electric control box 17, a wire feeding reel 16, a flux tray 23, a welding handle 20 and a control line 21. Several supporting rotary tires 1 are installed on the ground, and the boiler shell 2 is placed on the supporting rotary tires 1 . The boiler shell 2 and the drum head 15 form a circular weld, and an aperture is opened on the drum head 15, and an insulating sleeve 22 is placed on the aperture. The welding trolley is put into the boiler shell 2, and the welding trolley includes a welding torch 24, a wire feeder 14, a flux hopper 11, a horizontal adjustment slider 5, a longitudinal adjustment slider 27, a welding seam tracking device 3 and a walking trolley 4; a walking trolley 4 The seam tracking devic...

Abstract

The invention relates to a welding machine, in particular to an automatic welding machine for a boiler inner circular seam submerged arc. The automatic welding machine is composed of a welding trolley, a welding power source, an electric control cabinet, a wire reel, a flux tray, a welding cable and a control cable. A plurality of supporting rotating tires are arranged on the ground, and a boiler cylinder is placed on the supporting rotating tires. A circular welding seam is formed by the boiler cylinder and a boiler end socket. A small hole is formed in the boiler end socket and sleeved with an insulating sleeve. The welding trolley is placed in the boiler cylinder, and a welding seam tracker is arranged on one side of the walking trolley. A longitudinal adjusting sliding block is arranged on the walking trolley, and a transverse adjusting sliding block is arranged on the longitudinal adjusting sliding block. The transverse adjusting sliding block is provided with a wire feeder and a flux hopper. The flux hopper is provided with a remote control box. It is guaranteed that a weld gun does not leave the welding seam all the time, in the welding process, the welding trolley is located at the bottommost point of the boiler cylinder for welding all the time, and molten iron leakage due to weld penetration of the welding seam is prevented.

Description

technical field [0001] The invention relates to a welding machine, in particular to an automatic submerged arc welding machine for the inner circular seam of a boiler. Background technique [0002] The boiler shell is mainly composed of a cylindrical steel cylinder and two ball-like heads welded together. Welding of the inner and outer ring seams of the combination of the first head and the cylinder. It can be completed with the help of submerged arc welding operation frame and rotating tire. As for the inner ring seam of the combination of the second head and the cylinder, the submerged arc welding operation frame cannot be automatically welded because it cannot extend into the cylinder. For a long time, this inner ring seam can only be completed manually by manual arc welding. The disadvantages of manual welding are large welding deformation, long time consumption, low efficiency, difficult to guarantee welding quality, and people work for a long time in a smoky and har...
