Difference between three roll plate bending machine and four roll plate bending machineRelease Time : 2022-11-07 View Count : 次
Plate bending machine is a kind of general equipment that can bend metal plates into cones, spheres, cylinders or other shapes and is specially used for bending, forming and correcting metal plates. It is widely used in shipbuilding, chemical industry, boiler, water and electricity, pressure vessels and machinery manufacturing industries.
The types of plate rolling machines are different due to different fields of use. The number of rolls is divided into three roll plate bending machine and four roll plate bending machine.
So, what are the differences between the four roll bending machine and the three roll bending machine? Let's follow Ming Cheng to understand:
The four roll plate bending machine is applicable to the bending and forming of metal plates. It can roll round, arc and conical workpieces within a certain range. It also has the pre bending function at the end of the plate. The remaining straight edges are small, and the work efficiency is high. It can also roughly level the metal plates on the machine.
The upper roll of the three roll plate bending machine acts on the piston for vertical lifting movement through the hydraulic oil in the hydraulic cylinder at the central symmetrical position of the two lower rolls. The final gear of the main reducer drives the gears of the two lower rolls to engage and rotate, providing torque for rolling plates.
In addition, the roller motion forms of the four roll plate bending machine and the three roll plate bending machine are different. However, they all work in the same way, using the principle of three-point circle to roll with different radii.
There are many types of rolling machine, and the structure and performance of each type of product are quite different. Therefore, we should have a full understanding of them when purchasing, and we should not be blind.
