Four Roll Rolling Machine

The four-roll plate rolling machine is suitable for the bending and forming of metal sheets. It can roll round, arc and conical workpieces within a certain range. Sheet metal can be roughly leveled on this machine.

The performance of the rolling machine

Plate rolling machine is a kind of special forging machine equipment that can bend non-metallic sheets into cones, spheres, cylinders or other shapes. This performance is widely used in forging, boiler steam, chemical industry, non-metallic Structure and machine building business. There is almost no one-time machine that can be lacking in the changing machine business. It is because of its wide use by all walks of life that the high-speed development of the plate rolling machine business has occurred yesterday.

working principle

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-roller and three-roller rolling machines 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. However, the straight edge and roundness of the pre-bending of the four-roll rolling machine are better than those of the three-roller.

Safe Operating Procedures

1. The rolling machine must be managed by a special person.
2. The operator must be familiar with the structure, performance and use of the plate rolling machine, and can operate it only after the approval of the responsible management personnel.
3. Before starting the machine, carefully check whether the safety device is in good condition.
4. During operation, it is strictly forbidden to put hands and feet on the rollers, transmission parts and workpieces.
5. After the work is interrupted, the clutch should be turned to neutral.
6. Multi-person collaborative work must be directed by a special person.
7. Overwork is strictly prohibited.
8. The tilting and resetting of the lifting and turning bearing of the upper roller and the balance of the upper roller must be carried out after the main drive is stopped.
9. It is forbidden to pile up workpieces and sundries in the workplace, and keep the machine tool and the site clean at all times.
10. After the work is completed, the power supply should be cut off and the power box should be locked.
