Maintenance work carried out well or badly Bending depends first on staff conditions. Bending Machine maintenance staff must have the following requirements:(1) extensive knowledge, computer skills, basic analog and digital circuits, motor control and drag, detection technology and mechanical processing technology and a certain basic knowledge of foreign languages;

This upper roll of this machine not only can vertical fluctuation but also can level migration, the vertical fluctuation is the hydraulic transmission, it obtains the level migration through the hydraulic cylinder in hydraulic fluid act on connecting rod. Through the turbine bar box, the turbine wheel pole

Hydraluic 3-roller plate bending machine is a hydraulic three-roller bending machine and used to pre-bending of end of plate , rolling round,getting cone style and correct plate round as well as complete other processes at one feeding for all sorts of vessel carbon steel and low alloy steel plate as well as stainless steel under normal temperature without turning back.

4-roller plate bending machine,the main structure consists of upper roll, bottom roll, side roll, main drive device, tipping device, right and left supporting structure, and seat.The upper and the bottom rolls, which work as the main drive at the same time, provide drive by hydraulic motor.

Parameter: Upper roller force: 230 Tons Diameter of the upper roller: Φ420mm. Diameter of the lower roller: Φ235mm Central distance between bottom shafts: 380mm Max width of coiled plate: 3000mm Length of working rolls: 3100mm Max thickness of coiled plate
