Automatic submerged arc surfacing welding equipment for roller and welding method thereof

Abstract

The invention discloses automatic submerged arc surfacing welding equipment for a roller and a welding method of the automatic submerged arc surfacing welding equipment. The automatic submerged arc surfacing welding equipment for the roller comprises a control console and a positioner mechanism which are connected with a base, a welding slag receiving hopper mechanism mounted on the base, a supporting part detachably connected with the base, a position adjusting mechanism installed on one side of the base, and a submerged-arc welding device and a removing mechanism which are located on the position adjusting mechanism. When a removing part in the equipment begins to move, the moving removing part makes contact with blocky welding flux, the welding flux falls off from a welded area, then the falling blocky welding flux can fall into a receiving hopper, the blocky welding flux can be collected, submerged-arc welding of the roller can be completed, a working area can be kept clean and tidy, and workers are prevented from falling down due to the blocky welding flux.

Description

technical field [0001] The invention relates to a submerged arc surfacing device, in particular to an automatic submerged arc surfacing device for rolls, and relates to the technical field of submerged arc welding. Background technique [0002] Submerged arc welding is a welding method in which an arc burns under a layer of flux. Its inherent advantages such as stable welding quality, high welding productivity, no arc light and little smoke make it the main welding method in the manufacture of important steel structures such as pressure vessels, pipe section manufacturing, and box-shaped beams and columns. [0003] However, the existing submerged arc welding device has some problems during welding. After the welding of the existing submerged arc welding device, the flux will form lumps and be located in the welding area, and then it needs to be cleaned, while the buried arc welding device of the transmission None of the arc welding devices have this kind of function, and on...

AI Technical Summary

Problems solved by technology

[0003] However, the existing submerged arc welding device has some problems during welding. After the welding of the existing submerged arc welding device, the flux will form lumps and be located in the welding area, and then it needs to be cleaned, while the buried arc welding device of the transmission None of the arc welding devices have this kind of function, and only manual cleaning can be performed manually. With the increase of the welding speed of the submerged arc welding device, the manual cleaning speed cannot adapt to the welding speed of the device, which will lead to manual cleaning. The cleaning work is done very well, and the lumpy flux attached to the roll will fall to the construction area during the operator's handling, which will not only pollute the construction area, but also cause the workers to fall down. damage the health of workers
