Multifunctional cradle roll type roller series automatic submerged arc welding machine

Abstract

The invention relates to the technical field of welding technology equipment, in particular to a multifunctional cradle roll type roller series automatic submerged arc welding machine. The multifunctional cradle roll type roller series automatic submerged arc welding machine comprises a track type automatic submerged arc welding machine; the track type automatic submerged arc welding machine consists of a welding machine track, a welding machine plate trailer, a welding machine strut, a flexible cross arm, a welding flux feeding device, a welding gun, a welding wire feeding device and an electric control device with an operating platform; one side of the welding machine track is provided with a square pit; a front support and a rear support are symmetrically arranged on the edges of the two sides of the square pit; the front support and the rear support are rotatably connected with a cradle roll mechanism respectively; the upper surface of the cradle roll mechanism is provided with a power seat rotation chuck and a tail seat revolution chuck respectively; the lower surface of the cradle roll mechanism is fixedly connected with a counter weight device; and a positioning axis pin isarranged on the front support. By the multifunctional cradle roll type roller series automatic submerged arc welding machine, heavy and low-efficiency manual operation is changed into single-process mechanical automation operation, the welding line quality and production efficiency are improved, labor intensity is reduced and operating environment is improved.

Description

technical field [0001] The invention relates to the technical field of welding process equipment, in particular to a multifunctional pendulum type roller series automatic submerged arc welding machine. Background technique [0002] The hollow roll is a rotating part widely used in the metallurgical industry. This hollow roll has various types and specifications according to the shape and size of the application. The largest size can reach a roll diameter of about 1400mm and a length of about 5000mm. Its structure is It consists of a roller, a web welded to both ends of the roller, and a shaft head welded to the web respectively. The processing procedures are mainly between the roller and the web and between the web and the shaft head. The assembly butt joint process and the welding process after butt joint. The current welding methods include manual welding or gas shielded welding and automatic submerged arc welding machine. Since the weld seam of the hollow roll is multi-di...

[0002] The hollow roll is a rotating part widely used in the metallurgical industry. This hollow roll has various types and specifications according to the shape and size of the application. The largest size can reach a roll diameter of about 1400mm and a length of about 5000mm. Its structure is It consists of a roller, a web welded to both ends of the roller, and a shaft head welded to the web respectively. The processing procedures are mainly between the roller and the web and between the web and the shaft head. The assembly butt joint process and the welding process after butt joint. The current welding methods include manual welding or gas shielded welding and automatic submerged arc welding machine. Since the weld seam of the hollow roll is multi-directional, the above method is in the hollow roll welding process. During the process, the assembled hollow roller assembly must be upright, lying down and overturned several times with the help of a crane or auxiliary lifting equipment and basic fixing devices. The labor intensity is very high and the operation is also difficult, which makes the process cumbersome and poses a safety hazard. It is also relatively large, requiring more manpower and working hours. The work efficiency is low, and because the operator's level and sense of responsibility cannot be unified, it is difficult to guarantee the welding quality. The weld seam of the hollow roller is easy to crack during use, and the service life shorten
