The forming diameter is a primary device on the welded tube production line. The unit consists of a molding machine, a welding machine, a cooling device, and a portion of the diameter. This machine uses a roller type, high frequency induction welding, can be continuously produced, molded and a degree of diameter
1)Forming rack: Composed of seven flat roll racks and eight vertical roller racks, the rack adopts steel steel (ZG270-500) split structure, the rack and the hooded M36 bolt fixation, depressed
2)vertical roller rack: pull plate structure (pull plate two ends of the top plate), the axial diameter φ60mm (equipped with roll), the roller shaft material 40Cr, heat treatment: Treatment HB260 ~ 290 surface quenching h
3) The diameter device, the fixed diameter device has five flat roller racks and five vertical roller frame composition, the mechanism is formed, and the diameter device mainly controls the diameter of the soldered steel pipe.
4) The molding and differential diameter is a live platform, which can be replaced. Workbench
