Round to square pipe machine
1.Equipment Uses：The machine unit is cold rolling special use equipment by pushing and squeezing
the round pipe to square tube, rectangular tube or a variety of special tubes. The side length and wall
thickness of square and rectangular tubes produced based on the technology has reached the best in the
industry. The machine unit can also be used as cold sizing equipment of large and medium diameter steel pipes.
2.Equipment Structure：the equipment adopts the structure combined by universal stand with horizontal
and vertical roll symmetry in the same plane and the large thrust hydraulic pushing machine. It has solved
the problem of limiting special pipe side length and wall thickness in cold bending forming technology. The
tubes side length and wall thickness produced by this machine have been increased 1 to 3 times than active
roller machine and bending machine unit.The machine unit is composed of 4 sets of deformation racks and
1 set of straightening rack(Turkey Head),which will be installed on same ground plane. The machine unit push
power equipment is designed and manufactured according to patent principle of hydraulic two-step pushing
3.Square and Rectangular Tubes Technical Parameters:
1)Max：side length×side length＝800×800 ；wall thickness:35mm；
2)Min：side length×side length＝25×25； wall thickness:2mm
4)equip the suitable square and rectangular tubes forming rollers sectionally.
