1. The structure of main body of section bending rolls
The machine is made up of main frame, press down of top die device,
lower die device, and drive device, electric control and hydraulic
device. It is a kind of high-efficient process equipment used to
roll angle iron, channel steel,
flat steel, steel pipe and etc .It can be feed in one time, and
then complete the rolling round, re-round procedure, and it is
widely used in petroleum line, chemical industry, construction,
water & electricity, shipbuilding, and machinery line.
1) The main frame is welding part which is installed on the
chassis.
2) The top die device is made up of special-purpose die, shaft
seat, bearing block, oil cylinder and etc. it can do vertical
movement between the two lower dies under the pressure of oil
cylinder.
3) The lower dies is made up of main shaft, special-purpose die,
gears and etc, the gears of two lower dies mesh with the gear of
reducer as the main drive, it can do positive rotation and reverse
rotation, which can offer the torque to section.
4) The main drive device includes main motor, reducer gear and etc.
2. Overview
This machine is of three-roller symmetrical profile bending
machine, it is made up of oil cylinder, electric control console,
drive system, top roller, lower roller and dies. It is used to bend
and roll the angle iron, channel steel, I-section steel, round
steel, steel pipe and other special-shape steels,
It can be feed in one time, and then complete the rolling round,
re-round procedure, and it is used in petroleum line, chemical
industry, construction, water & electricity, shipbuilding, and
machinery line.
The machine is of advanced structure (two lower dies doing arc line
movement around one center to adjust the diameter of the rolled
products), stable working performance, complete-function and is the
advanced section formed equipment in domestic and abroad.
3. Techniques software
The machine adopts hydraulic pressing, so the pressure is large and
the performance is stable. The operation table is set with
indicators for each part’s movement, and it also can be controlled
remotely, being of the high automatic level, convenient operation,
safety and low failure rate.
