Box beam build up line UBZ12 (welding machine) is used in petrochemical machinery, engineering machinery, wind power equipment, construction & bridge, shipbuilding, food & pharmaceutical and other industries
Ⅳ.UBZ12 Assembling machine
1)Structure principle
This machine is composed of gantry frame, support working table, feeding rollgang, hydraulic system and electrical control system. Gantry frame is the main part of this machine, all the tightening device installed on it. The moving of frame is driving by two motors on the below moving beam through worm gear reducer and rack reducer to bring two wheels moving on the track, the track adopted standard 38kg/m heavy track and between the two parallel track is connected by high strength drag bar which avoid the track stretch out like“八” after get counterforce of right-left oil cylinder and guaranteed the assembly quality. The rollgang turning by cycloid speed reducer driving chain, is mainly used to assembling and conveying workpiece. When assembling, put the workpiece on the platform composed by several rollgang, and the up press cylinder and side cylinder tighten the web and flange plate, then do spot welding to tightening part and through the moving of frame to weld the whole workpiece.
