Description:Product Name: Four-Roller Plate Bending Machine (EZW12-40 x 3,000mm)Model Number: 8462299000Place of Origin: ChinaIndividual roller driven: hydraulic four-roller plate bending machine owns national patent, which was first invented by Ezhong. Its function lies in that it may enable the machine to greatly satisfy the technical requirement of thick plate bending. Top-located cylinder: it is designed on the basic of many years' research. It absorbs the advantages of several Japanese, German, and Chinese models. Its advantages are: a. Both cylinders work without rod cavity, so the effective area is large b. Compared with the in-backseat cylinder, maintenance is more convenient c. Only one dynamic sealing, air holding property and reliability are excellent d. Lifting speed fits to bending process. Throttle is not necessary, so oil temperature is low and energy consume is small Complete machine backseat: Ezhong horizontal four-roller series adopt once-through welding structure. Compared with assembled backseat, it has no assembly tolerance and accumulated processing tolerance after annealing. The installation is also convenient. The middle of machine backseat is wide, and the two ends which are connected with machine frame are relatively narrow. The whole machine backseat has large height, and sufficient overall intensity and rigid. One extreme case is, one W11S-120 x 3,000 full load pre-bent six pieces of 110mm steel plate without ground fixing. That is impossible for any other similar machines. Horizontal-moving device: Ezhong machine adopts mechanical drive. Ezhong's outside-laid device is located in the outside of machine backseat, so the maintenance and repair is convenient. Meantime, it leaves more space for bottom roller bearing seat. Apart from that, rolling bearing is used, which apparently reduces main motor power, saves energy, and is easy to lubricate. Cone bending: cone-bending device on roller-style bending machine owns national patent. Work range of cone bending is greatly increased. Plates of various thicknesses can be processed, and most requests on taper can be satisfied. Hydraulic system: a. Hydraulic components are from Chinese famous brand b. Control points are distributed in each inlet and outlet, so that maintenance and failure inspection are convenient c. The manufacture of hydraulic system strictly follows national standard and industry standard. Its curving diameter is reasonable and well distributed d. The whole design takes full consideration on energy saving. So power waste and heat resource are greatly reduced e. Trouble shooting on hydraulic system is available f. In order to guarantee quality, whole hydraulic system is produced according to Chinese standard Controlling system: a. Screen display b. Calculation c. Programmed control d. Data storage e. Soft protection to give alarming or limiting on the extreme stroke f. Man-machine dialogue
