Four-roller rolling machine advantage

The four-roller rolling machine working principle: The rotation of the upper roller on the rolling machine is mostly mechanical rotation, and the lower roller and the two side rollers are usually hydraulically driven.

Advantage:

1. The material pre-bending needs only one feeding.

2. It can be rolled in many shapes, including round, curved, and tapered under certain conditions.

3. The material plate can be shaped and flattened directly on the device.

4. Horizontal feeding of the board - not as inclined as the three-roller

5. Use the side rollers to quickly align the plates (r avoids the risk of misalignment)

6. Only occupy space on the loading side

7. The edge of the straight section is greatly reduced (from the outstanding pre-bending ability, the clamping point is completely at the edge of the board)

8. The easiest equipment to roll, each side roller only needs one position to roll forming

9. The whole process is formed once (provided that the equipment capability option is appropriate) including the pre-bending of the head

10. Post-rolling of the sheet is suitable for efficient automatic roll manufacturing

11. It is most suitable for CNC automatic rolling - the sheet is always clamped between the upper and lower rolls: eliminating the slip phenomenon, which is 50-80% higher than the speed and efficiency of any three-roller rolling machine. The use of CNC automatic winding reduces the need for initial skill in the operation of the tool because the four-roller operation and control are the easiest.

12. Without any experience in the coil, seeking efficient rolling equipment to maximize profits. Seeking high-precision and high-quality products in the process of large-scale workpiece rolling, pay attention to the rationality and safety of the production process.

Disadvantages:

1. When working, the two side rollers need to change positions multiple times, which reduces working efficiency.

2. The structure is complex and is not conducive to maintenance and maintenance.
