features of W11S series plate rolling machine
This plate rolling machine is a new type of plate rolling machine based on the introduction of domestic and foreign advanced technology and combining domestic actual conditions. Because its electrical control system uses a displacement sensor, coupled with PLC programmable controller (Japan OMRON products), touch screen PC, it can automatically detect the position of both ends of the roller and its real-time monitoring to ensure synchronization accuracy. Not only can the product be pre-bent and quickly coiled, but it also has the characteristics of high precision of the rolled product, no auxiliary equipment, and low investment.
The roll on the plate rolling machine can move vertically and horizontally, and when it is pre-curved, it moves horizontally through the upper roll so that the upper roll is asymmetrically positioned with respect to the lower roll. When rounding through the motor, the reducer drives two rollers. Because the elevation of the lower roll is constant, it is easy to feed and operate.

structure of W11S series plate rolling machine
The W11S series palte bending machine also has the dual functions of pre-bend and roll round (arc). The main structure of the equipment consists of upper roll device, lower roll and horizontal moving device, roller device, main drive device, and turn Pour device, left and right side racks and chassis. The main drive can be used for positive and negative reversal to provide coiling torque for the rolling of the sheet.
1.Upper roller device
The upper roller device is mainly composed of a main oil cylinder, upper roller bearing seat, upper roller, double row self-aligning bearings, and the like. The two main cylinders provide the required pressure for rolling the plates. The main cylinder operates at 19.5 Mpa.Upper roll material 42CrMo, according to JB/ZG4289-86 roll steel standard, hardening hardness HB260-300, surface quenched HRC42-50.
2.Lower Roller and Horizontal Mobile Device
The lower roller device consists of a lower roller, a lower roller bearing seat, a lower roller input gear, a lower roller sliding bearing, and the like.The lower roller main drive powers the main drive output gear, the lower roller input gear, and the open drive torque to the lower roller.
Roller material 42CrMo, Hardening hardness HB260-300, surface quenched HRC42-50.
The horizontal moving device is composed of a horizontal moving motor, a worm gear box, a worm gear and the like. The horizontal moving device is powered by a horizontal moving motor and drives the horizontal movement of the upper roller through the worm gear box, the worm gear, the screw and screw mechanism, and realizes the asymmetric rolling of the plate.
