Rolling Machine (W11STNC-16*2500)&plate rolling machine&hydraulic rolling machine


This machine belongs to hydraulic three rollers plate rolling machine. It is used to pre-bend and roll the low carbon steel plate and low alloy steel plate to barrel, circular or conical shape in normal temperature.


The two lower rollers as the main drive and the upper roller marking vertical and horizontal movement so that it can finish the end pre-bending work and coiling work at the same machine. The main drive comes from the work of the main motor and the main speed reducer. The upper roller moves vertically by hydraulic drive so that the pressure is powerful and the speed is fast. The upper roller moves horizontally by mechanical transmission, both the speed and efficiency are high.


The upper roller will be in an asymmetrical position compared with the two lower rollers when the upper roller moves horizontally. In this state, the ends of the plate can be pre-bended by the direct pressure on the upper roller. Operators can set the length of the straight edge freely.

Due to the standard height of the two lower rollers, it is convenient to feeding and operating. The products of excellent accuracy can be obtained from continuous rolling and end pre-bending of high precision. Hydraulic overturned device makes the efficiency enhanced greatly.

NC (numerical control) makes the production of high efficiency. The machine runs smoothly and can be controlled with easy. There is no resistance or jamming, the phenomenon of oil leakage or abnormal noise. All these advantages make the machine of high reliability and low failure rate.


There is a detailed electrical schematic diagram with each machine. And the installation of electrical wires is carried out in strict accordance with the electrical schematic diagram. The number at both sides of each connected wire is complete and clear. There are the same corresponding tag numbers and signs on the terminal board and the electrical schematic diagram.


All electrical equipments are high-quality products from famous enterprises. Electrical protective devices (such as current relay, control switch, etc.) are installed prior to rigorous testing to ensure reliable operation.




Using drum-shaped upper roller, the preset volume of the upper roller is generally uniform load of 70% of rollers to preset, smaller diameter of the roller, the lower part of the lower roll has the support roller adjusting up and down to support. According to the load of the rolling products, adjusting the support roller under the lower roller, enhancing the straightness of the products.



The upper roller universal rolling machine adopts the rear rolling. The direction of the plate putted into is opposite to the direction the upper roller running. When the upper roller is doing pressure work, the lower rollers run at the same time. The products of excellent accuracy can be obtained from continuous rolling and end pre-bending of high precision. The end pre-bending of the plate is directly enhance pressure and pre-bending, avoiding appearing the dorsal horn of anterior bending, and can control the length and shape of the remaining straight edge.


General non-symmetric three-roll form using the anterior bending. First, make pre-bending work on the two ends of the plate. Then coil the plate to be circular shape, it needs skilled employees, the products appearing the dorsal horn phenomenon, and the shape of remaining straight edge is difficult to control.



The Upper roller Universal Rolling Machine takes the following measures on reducing the edge offset of the products:


The two lower rollers,the dimensional accuracy of the two rollers center distance, geometric tolerance as a key process to control.


The movement of upper roller adopts synchronization electro-hydraulic combination and the feedback system, automatic leveling. The fuel tanks trip of the upper roller is tested by the rotary encoder, compared by the controller, high and low to the programmable logic controller to control the roll at both ends of the electromagnetic solenoid valve, relatively continuous to feedback and compare.
