Application Advantages of 4-roll Plate Bending Machine


I. what is the 4 roll plate bending machine


The roll plate bending machine is a kind of special forging machine equipment that can bend non-metallic sheets into cones, spheres, cylinders or other shapes. Machine building, etc. The 4 roll plate bending machine is suitable for the bending and forming of metal plates. It can roll circular, arc and conical workpieces within a certain range, and it also has the function of pre-bending the end of the plate with small remaining straight edge and high working efficiency. Sheet metal can be roughly leveled on this machine. The straight edge and roundness of the pre-bending of the 4 roll plate bending machine are better than that of the three roll bending.


The position of the upper roller is fixed, and the lower roller moves straight upward to clamp the steel plate. The rollers on both sides move toward the upper rollers in a straight line or in an arc to adjust the radius of curvature of the roll. The four and three roll plate bending machine have different rolling motions, but the working principle is the same. They all use the principle of three-point circle to roll with different radii. The 4 roll plate bending machine has good comprehensive mechanical properties, high strength, strong wear resistance, suitable for high-load work and long service life.


II. What are the application advantages of the 4 roll plate bending machine?


1. The work bearing of the 4 roll plate bending machine adopts rolling bearing, which has a small friction coefficient, reduces reactive power loss and saves energy.


2. The upper roller is rotated and installed with an encoder, which can pinpoint the rotation position of the roller and is easy to find the seam of the coiled tube.


3. The lifting and lowering displacement of the lower and side rollers of the 4 roll cnc plate bending machine is controlled by the computer, with automatic leveling, digital display on the screen, and synchronization accuracy of ±0.2mm. The coiling has high precision and easy operation.


4. The 4 roll plate bending machine is equipped with a movable operating table, which is more convenient for operators to use. The touch screen displays the positions of the three work rolls, so that the operator can see at a glance.


The 4 roll plate bending machine consists of four rollers. The upper roller is the main drive and the position of the upper roller is fixed. The two ends of the lower roller are driven up and down by hydraulic cylinders. The lower roller can be raised so that it can clamp the head of the sheet with the upper roller, and the head of both ends of the sheet can be bent by changing the distance between the side roller and the upper roller as required. Then the lower roller is lowered, the two side rollers are raised, and the sheet is bent into a cylindrical shape. EZHONG 4 roller plate rolling machine for sale is convenient for the centering of the sheet during rolling, and the process is versatile, which can correct the defects such as skew and misalignment during rolling; at the same time, the end pre-bending and rolling of the sheet can be completed in one feeding. the remaining straight edge is small, which is an ideal equipment for rolling round and arc workpieces.
