The difference between 3-roller plate rolling machine and 4-roller plate rolling machine

The difference between 3-roller plate rolling machine and 4-roller plate rolling machine   

What are the advantages of 4-roller plate rolling machine

Difference between 3-roller plate rolling machine and 4-roller plate rolling machine.

1. Different number of rollers

In terms of the number of rolls, the 3-roll coiler is 3 roll shafts, one upper roll and 2 lower rolls. And 4-roller coiler is 4 roller shafts, one upper roller, one lower roller, two side rollers.

2. The model number is different

3-roll coiler usually refers to W11 series, 4-roll coiler usually refers to W12 series.

3. Differences in machining precision

The processing precision of the 3-roller plate rolling machine is lower than that of the 4-roller plate rolling machine, and the 4-roller plate rolling machine can realize higher processing precision.

4. Different processing efficiency

The processing efficiency of the 3-roller coiler is lower than that of the 4-roller coiler, and the 4-roller coiler can realize higher processing efficiency.

5. Price difference

The price of a 3-roll coiler is lower than that of a 4-roll coiler, and the price of a 4-roll coiler is higher.

6. Differences in applicability

3-roller plate rolling machine is cost-effective, but rolling is more time-consuming and the products have straight edges. The 4-roller plate rolling machine has high rolling precision, small straight edge, fully automatic operation, and is suitable for batch production of products.

What are the advantages of four-roller plate rolling machine

1. High efficiency: 4-roller plate rolling machine is easy to operate, can quickly complete the rolling operation, improve production efficiency.
2. Better roll quality: The 4-roller coiler can get better roll quality and precision by adjusting the pressure and roll angle.
3. Wide applicability: 4-roller plate rolling machine can be used to roll plates of various strengths and thicknesses with strong adaptability.
4. Additional equipment is complete: 4-roller plate rolling machine additional equipment is more complete, can be equipped with automatic feeding, automatic plate rolling and other equipment.
5. High reliability: 4-roller plate rolling machine has the advantages of simple structure, easy operation, easy maintenance, durability and so on, which guarantees the reliability of the equipment.
6. Save land: Compared with other types of plate rolling machine, 4-roller plate rolling machine needs relatively small land, which can save production space.

 

4-roller plate rolling machine has the advantages of high precision, high efficiency, simple operation, safety and reliability, etc. It can effectively meet the requirements of modern manufacturing industry for high precision, high efficiency, safety and reliability, etc., and plays an important role in the field of metal material processing.

 

Parameters of 4-roller plate rolling machine rolled round

1. Thickness and hardness of rolled material

The thickness and hardness of the material to be rolled affects the rounding ability of a 4-roll coiler. Thinner materials are relatively easy to roll, while thicker materials require greater rolling force.

2. Control System for Rolling Machines

Different 4-roller coiler control systems have different parameter setting methods and specification requirements. Before setting, you need to know the specific control system of the machine used.

3. Dimensions and angles of the 4 rolls of the coiler

The size and angle of the 4 rollers of the 4-roller coiler are also factors that affect the ability to roll round. The larger or smaller the size and angle of the rollers, the effect of rolling round may be affected.

 

4-roller plate rolling machine how to set automatic rounding parameters

1. Open the automatic roll control system, select the “Specify roll size” option, and enter the diameter of the circle to be rolled.
2. According to the thickness and hardness of the rolled plate material, set the size of the rounding force. In general, thinner materials can be appropriately reduced rounding force, thicker materials need to increase the rounding force.
3. Set the position and angle of the 4 rollers of the coiler. Determine the position and angle of the 4 rollers according to the required size of the rolled circle and the size of the rolling force. When setting the position and angle, adjust them carefully to avoid affecting the rolled plate material.
4. After completing the parameter settings, the machine will follow these parameters when automatic rounding occurs in the coiler.

 

Operation process of 4-roller plate rolling machine

1. The steel plate is placed between the upper and lower rollers, and the upper and lower rollers clamp the steel plate.
2. Raise one side roll up and the steel plate against the side roll to square the sheet.
3. The rolls rotate and bring the steel plate to the pre-bent position with the end of the plate at the centerline of the upper and lower rolls.
4. The side rolls rise for pre-bending of the plate ends.
5. Measure the curvature of the end, in a number of passes, and pre-bend to the required curvature.
6. Adjust the position of the side rollers so that one side roller is lowered and the other side roller is adjusted to rest against the sheet.
7. The rollers are rotated for rolling, and the position of the side rollers should be adjusted with care during rolling.
8. In this position, the other end of the plate is pre-bent and the cylinder is formed.
