4-roll Sheet Metal Cone Rolling Machine/4 Roll Dual Initial Pinch / Conical Plate Roll

BIT 4-roll Sheet Metal Cone Rolling Machine is specially used for rolling cones. Featuring high efficiency, low energy consumption, and easy operation, this cone-bending machine’s performance is superior to other rolling machines in China. The main structure of the 4-roll cone plate roller adopts the cone roller method. There is no mutual sliding between the workpiece and the roll surface.

Advantages

This cone rolling equipment owns high rolling efficiency. This cone bending machine is suitable for a single variety and mass production.
An obvious advantage is that the four roller cone plate rolling machine can feed materials once without the aid of auxiliary devices.
The upper roll is the main drive roller. Motive power is engaged with the upper roll through the planetary reducer, which provides torque to the rolling plate. The lower roll of the cone bending machine can move vertically to clamp the plate. The side rollers of the four roller cone plate rolling machine are installed on both sides of the lower cone roller. They can move up and down driven by the cylinder.
This cone bending machine can also finish the pre-deformation of both ends of the plate.

3 Steps for Sheet Metal Cone Fabrication

Rolling cylinders and cones on a Sheet Metal Cone Rolling Machine are based on the principle of three-point bending. The sheet metal cone fabrication process mainly includes the following three steps.

Step 1#: The workpiece is fed into the work roll of a sheet metal cone rolling machine(plate rolling machine), and a roller is on the workpiece.
Further Reading: Above the top is called the top roller, two below the workpiece, called the lower roller, which is a 3-roll bending machine; the 4-roll bending machine has three rollers below the workpiece and one inside the same vertical plane of the top roller, called the middle-lower roller, the other two on both sides of the upper roller, called the side roller, the upper roller can bend the workpiece with any two rollers of the side roller and the middle-lower roller.
Here, we only discuss two rollers or sides the symmetrical arrangement of the roller and the upper roller;
Step 2#: The working roller moving feed the sheet, three-point bending, some of the plate rolling machine is the top roller for feeding down, and some of the lower roller or side rollers for upward movement, according to the principle of relative motion, the workpiece and the lower roller or side roller as stationary, the upper roller for the depressing movement; the volume of the cylindrical workpiece on the roller is parallel with the lower roller, roll When the roller is pressed down by the roller on the workpiece, it is inclined with the lower roller; the more the pressing amount is, the busbar and the nearby curvature that the workpiece is in contact with the upper roller the larger;
Step 3#: The work rollers by rotational movement so that rotation of the workpiece while maintaining constant the amount of reduction on the roller, so that each piece of the bus bar has the same curvature or a curvature distribution, and a cylindrical cone.
