Instruction

This machine used to make the steel plate into barrel shapeCircular shapeConical sharp, etc.

The upper roller can move vertically as well as horizontally, it can finish the pre-bending work and coiling work at the same machine.

The upper roller is drum-type design, so it has the anti-deformation function. There is equipped the support rollers under the lower rollers it can help to coil the high precision products.

The lower rollers are fixed symmetrically deployed relatively to upper roller, mechanical drive is employed for driving lower rollers. Upper roller ascends or descends at the central symmetric location of the lower rollers; the ascending and descending are hydraulic driven. Upper roller moves to the left or right position to prepare for pre-bending work, the shift position is controlled by the limited switches. The upper roller movement is PLC controlled and LCD display is employed for displacement.

Hydraulic drive is employed for dumping and resetting of the reverse head unit.

Moving control is employed for the control system; you can operation the machine at any position around the machine.
