Composition of the plate rolling machine

Figure 1  Composition of the plate rolling machine


Plate rolling machine is a kind of equipment that uses work roll to bend sheet metal forming, can form cylinder shapes parts, conical shape parts and other different shapes of parts, is very important processing equipment. The working principle of the plate rolling machine is through the action of external force such as hydraulic pressure and mechanical transmission power, so that the work roll movement, so that the plate bending or bending forming. According to the rotation of different shapes of the work roll and position changes, can be processed oval parts, arc-shaped parts, cylindrical parts and other parts. The most commonly used is the three-roller rolling machine, Figure 1 is the composition of the ordinary three-roller universal rolling machine.

Figure. 2 and Figure. 3 shows the working principle of the three-roll plate rolling machine: the upper roll acts on the piston for vertical lifting movement through the hydraulic oil in the hydraulic cylinder, and the last gear of the main reducer drives and controls the movement of the upper roll. The metal plate through the rolling machine's three work rollers (two lower rollers, one upper roller), with the help of the upper roller's pressure and the rotation of the lower roller, the metal plate after a number of continuous bending, permanent plastic deformation, rolled into the required shape. The disadvantage of the hydraulic three-roll plate winding machine is that the end of the plate needs to be pre-bent with the help of other equipment.


The above is the composition and working principle of the three-roll plate winding machine, I hope to let you have a deeper understanding of this machine.
