What is rolling machine?

Rolling machine is used to roll metal sheet into cylindrical, arc, fan, cone and other workpieces. It is general equipment specially used for bending, forming and correcting metal sheet, pressure vessels and machinery manufacturing industries, has a wide range of applications.

How does a rolling machine work?

The upper roller of the symmetrical rolling machine is at the symmetrical position of the center of the two lower rollers. The hydraulic oil in the hydraulic cylinder acts on the piston to make vertical lifting movement. The plastic metal sheet with flat specification passes between the three work rolls (two lower rolls and one upper roll) of the rolling machine. With the help of the lower pressure of the upper roll and the rotational movement of the lower roll, the metal plate is continuously processed through multiple passes. Bending (the inner layer is compressed and deformed, the middle layer is unchanged, and the outer layer is stretched and deformed), resulting in permanent plastic deformation, and rolled into the required cylinder, cone or part of them.

What are the classifications of rolling machines?

Rolling machines have different types depending on the field of use. According to the number of rolls, it is divided into three-roller and four-roller. The three-roller is divided into a symmetrical three-roller plate rolling machine, a horizontal-down three-roll plate-rolling machine, an arc-down-type plate-rolling machine, an upper-roll universal three-roll plate rolling machine, and a hydraulic CNC plate rolling machine. From the transmission, it is divided into mechanical type and hydraulic type. In terms of the development of the plate rolling machine, the upper roll universal type is the most backward, the horizontal downward type is slightly advanced, and the arc downward type is the most advanced.

How to maintain the rolling machine?

1. According to the regulations in the machine lubrication diagram, add oil to each oil cup lubrication and manual lubrication points as required.

2. Roll the plate according to the parameters specified by the plate rolling machine, the thickness of the plate is 20mm, the maximum length is 2500mm, and the yield limit of the plate material is less than 250Mpa.

3. After the power is turned on, carry out the forward and reverse directions of the lower roller and the lifting and lowering of the upper roller, and check whether there is any abnormal stuck phenomenon in each movement.

4. Operate in strict accordance with the rolling process procedures and operation methods, and pay great attention to the safe operation of the equipment when the upper roller is lifted to the limit position.

5. When the main drive stops, the upper roller can be lifted and lowered, the overturned bearing can be tilted and reset, and the upper roller can be lifted.
