The invention discloses a
pipe making
machine which comprises an unwinding area, a forming area, a
welding area, a
polishing area, a straightening area and a
cutting area. The unwinding area, the forming area, the
welding area, the
polishing area, the straightening area and the
cutting area are sequentially arranged along a roll material steel plate conveying direction. An unwinding shelf is placed in the unwinding area and is used for placing roll material
steel plates; multiple groups of
pipe fitting forming mechanisms are placed in the forming area and are used for gradually forming the
steel plates into round pipes; and a
welding mechanism is placed in the welding area and is used for welding gaps on the round pipes. The
pipe making
machine has the beneficial effects that (1) by applying the unwinding shelf to the pipe making
machine, materials can be conveniently unwinded and winded, so that the material unwinding and winding efficiency is high, and the 'zero' time for replacementcan be realized by adopting double-
station unwinding; and (2) by adopting the side wheel seat forming mechanism, a right-and-left threaded screw rod drives two slide block nuts to gather together toward the middle or be separated toward two sides at the same time, so that the position of a forming mould is quickly adjusted; and the positions of the upper ends of two fixed shafts are adjusted andlimited through an adjusting
assembly, so that the position stability of the forming mould in
production engineering is ensured.
