Plate rolling machine is a kind of equipment that uses working rolls to make plate bending and forming, and it can form different shapes of parts such as cylindrical parts, conical parts and so on. The working principle of the plate bending machine is to make the working roll move through the action of external forces such as hydraulic pressure and mechanical force, so as to make the plate bending or coiling and forming. According to the rotary movement of different shapes of work rollers and the change of position, it can process oval parts, curved parts, cylindrical parts and other parts, and it is not a big deal to roll the thick steel plate into a circle.
The operation principle of the rolling machine is that the upper and lower two rollers play a role in tightening the plate, the side two rollers diagonally push up and down to extrude the plate, computer programmed control, automatic rolling into shape.
When the rolling is completed, the side is opened automatically without manual operation.
The advantage of this rolling machine is that the end of the plate can be pre-bent, so that the rolled out cylinder without straight edges, rolled round one side of the molding. This machine can also roll triangles, ovals, squares, etc., realizing mechanized automatic operation.
CNC four-roller plate rolling machine is equipped with programmable CNC system, which can store hundreds of automatic rolling data of different workpieces, realizing one-key call and one-key start. No need for manual operation, automatically complete the workpiece rolling.
This model not only meets the automatic rolling processing of round, but also meets the automatic rolling of various arc, square, triangle, flat circle, oval and other workpieces. The operating system is equipped with EPS electronic automatic leveling system, which can automatically adjust the parallelism of the movement axis to ensure product quality.
The equipment material, pre-bending, rolled round in a rolling process is completed, pre-bending the remaining straight edge amount of ≤ 5 times the thickness of the plate, rolled round high precision, can meet the requirements of automated welding.
Parameters of four-roller plate rolling machine rolled round
Features: W12HG CNC four-roller rolling machine is our company has independent intellectual property rights with a variety of workpiece data programming and storage, automatic one-button rolling to complete the function of the fully automated roll bending equipment
Four-roller plate rolling machine is full servo automatic type, used to roll the steel plate into cylinder, square, oval, D-type; using computer program control system.
Before setting the parameters of automatic roll rounding, you need to know the following parameters: thickness and hardness of the rolled plate material: the thickness and hardness of the rolled plate material will affect the roll rounding ability of the four-roller plate rolling machine. Thinner materials are relatively easy to roll round, while thicker materials require greater rolling force.
Ellipsoidal Cylinder Rolling
Step-by-step process of elliptical coiling
Position the flat metal plate and feed the sheet so that it is parallel to the rear pressure roller.
Lifting the lower rollers so that the sheet is clamped between the two center rollers to obtain the desired clamping force.
Return to the cutting point, pre-bend stage, lift the side rollers and start rolling.
Return to center of formed sheet for yoke opening
Cylinder ends closed without overlap
