What is the main working principle of the three-roller rounding machine?

The main working principle of the three-roller rounding machine is based on the principle of plastic deformation of the material. Through the precise cooperative operation of the three rollers, the metal plate is continuously rolled and rounded, thereby shaping a circular tank that meets the requirements. The three-roller spheronizing machine requires a series of preparations and adjustments before working. The operator precisely adjusts the spacing and angle of the three rollers according to the required diameter and height of the tank. The position and spacing of the work roll and the reduction roll determine the stress and deformation of the plate during the rolling process, so the adjustment process needs to be very careful and precise.

When the machine is started, the work rolls begin to rotate and drive the metal sheet into the rolling area. The plate is subjected to strong pressure and friction between the work roll and the reduction roll, resulting in plastic deformation. The function of the reduction roller is to further compress and plasticize the sheet, making it gradually thinner and change its shape.

During the rolling process, the metal sheet is continuously pushed forward by the rollers and is subjected to continuous rolling force. The plate gradually changes from a flat state to a circular state, and through the continuous action of three rollers, the required tank diameter and shape are finally obtained. During the entire rounding process, the operator needs to always pay attention to the operating status of the machine and make necessary adjustments according to the actual situation. For example, depending on the material and thickness of the sheet, it may be necessary to adjust the pressing force of the reduction roller or the rotational speed of the work roller to obtain the best rounding effect.

After completing the rounding operation, the operator needs to stop the machine and perform subsequent finishing work. This may include cleaning the work area, checking the status of the machine, and preparing materials and tools for the next job.

In general, the core of the working principle of the three-roller rounding machine is to use the coordinated movement of the rollers to achieve continuous rolling and rounding of metal sheets. In this process, precise adjustment, reasonable operation and timely maintenance are key factors to ensure the rounding effect. Through continuous technological improvement and innovation, the three-roller spheronizing machine has become one of the indispensable and important equipment in the metal processing industry.
