Large round-to-square tube shaped unit

The main products of
square rectangular pipe forming machine include: 200 square, 300 square, 400
square, 500 square, 600 square and 1000 square forming units.

The large-scale
thick-walled special-shaped pipe forming unit produced by our company adopts
the ¡°circular
square¡± process,
which is a method of extruding a circular welded pipe or a seamless steel pipe
into a shaped pipe such as a square steel pipe or a rectangular steel pipe. Its
production products are mainly large-diameter, thick-walled square, rectangular
steel pipes and shaped pipes.

The main features of
the forming unit:

l  The
forming area consists of a plurality of universal models and straightening
machines composed of mutually symmetrical vertical rolls;

l  All flat
rolls are adjusted by hydraulic motor and worm gear, which greatly reduces the
number of forming units. The labor intensity of the operator also greatly
improves the efficiency;

l  The
transmission has two stages of deceleration, and has a large speed reduction
ratio and a large output torque. The distribution box adopts helical gear
transmission, and its advantages can withstand large torque. It avoids the
disadvantages of the traditional bevel gear box transmitting torque.

l  The
vertical roller adopts the overall box type, and the roll changing is
convenient and fast.

l  The finite
element method is used. Calculate the strength of parts in the product,
optimize the product structure and parameters;

l   Apply displacement sensors to quickly adjust
the hole shape of the equipment to meet the requirements of precision operation
of the equipment.
