How to buy a rolling machine

Because the plates that need to be processed in different industries are different, the rollers that need to be purchased are also very different. This article will introduce the various types of rolling machines and their features in detail, helping the majority of purchasers to take less detours when purchasing the rolling machine.

Two rolling machine

It is a relatively old-fashioned bending machine, which is only suitable for thin sheets with a high strength of 6-10mm. Its upper roller is fixed and can be rotated, and the lower roller has a vertical lifting function.

Wide range of applications, rapid production of thin-walled tubes, ventilation ducts, fans, chimneys, filters, solar water heaters, automotive exhaust pipes, liquid storage (gas) tanks, etc.

Three rolling machine

1 Symmetrical three rolling machine

Although the structure of the rolling machine is relatively simple, it has a wide range of applications. The disadvantage is that there is no pre- rolling function. After the rounding is completed, the remaining straight edges are large, and the additional crimping equipment needs to be purchased. The three rollers of the rolling machine are distributed in a "pin" shape, the upper roller can be vertically raised and lowered, and the two lower rollers are fixedly rotated, which is the main driving roller.

2 Asymmetric three rolling machine

The upper roller of the rolling machine is biased to the lower roller on one side, and the roller on the side can be vertically raised and lowered, and the roller on the other side is inclined to rise and fall. The asymmetric three-roll rolling machine has the function of single-side pre- rolling. If both sides of the board are pre-bent, the head needs to be turned. The roller is suitable for medium and thin sheets.

3 Vertical down type three rolling machine

The roller rotation on the roller is fixed, and the lower roller can be vertically raised and lowered. The biggest advantage of the rolling machine is that it can be bi-directionally pre-bent. It is suitable for medium and thin thickness plates. Pre- rolling and winding are only required to be fed once, which can greatly save the time for processing plates.

4 Tilt down type three rolling machine

The rotation of the upper roller of the roller is fixed, and the lower rollers on both sides are tilted. It can also perform two-way pre- rolling, and the rounding and pre- rolling can also be carried out once, which is suitable for medium and thin plates.

5 horizontal down-regulation three rolling machine

As the name implies, the upper roller of the rolling machine can be vertically raised and lowered, and the lower roller is horizontally moved, enabling bidirectional pre-bending, which is suitable for sheet rolling of various thicknesses. Ideal for rolling of medium and thick sheets.

6 arc down type three rolling machine

The upper roller of the rolling machine is fixedly rotated, and the two lower rollers are raised and lowered around a fixed center to enable bidirectional pre- rolling, which is suitable for rolling of plates with a thickness of 80 mm or less, and is more favorable for rolling of thick plates. .

7 Upper Roller Universal Three Rolling Machine

The upper roller universal three-roller is also known as the upper roller cross-moving rolling machine because the upper roller of the winding machine can move both vertically and horizontally. Capable of bi-directional pre- rolling for plates of 80-100mm thickness.

Four rolling machine

The four rolling machine can be divided into a common type of rolling machine and an arc type rolling machine. The rotation of the upper roller of the ordinary four-roller rolling machine is fixed, and the lower roller is vertically lifted, and the rollers on both sides perform the inclined lifting movement. The upper and lower rollers of the arc-shaped rolling machine are moved in the same manner as the ordinary four-roller rolling machine, and the rollers on both sides are moved up and down around the fixed point. Compared with the three rolling machine, the four rolling machine has higher precision and can roll 80-100mm thick plates, and the winding efficiency is also higher.

This article only gives a simple explanation for the rolling machine. If you need to buy a rolling machine, you need to according to your needs, such as what kind of plate you want to roll, what kind of shape, labor cost, volume The purchase budget of the board machine, etc., will be discussed in detail.
