How does a CNC small four-roll plate rolling machine complete the rolling of special-shaped parts?

Below, we will show you the rolling process of L-shaped one-time forming by a four-roll plate rolling machine with a customized 2mm thick stainless steel material and a width of 1 meter.

1. Preparation: First, cut the 2mm thick stainless steel plate to the appropriate size and ensure that the surface of the plate is flat and has no obvious defects. Then, according to the size and curvature requirements of the L-shaped special-shaped parts, enter the corresponding programming parameters in the CNC system.

2. Plate positioning and clamping: Put one end of the cut stainless steel plate into the upper and lower rollers, the equipment starts to run, and the upper and lower rollers clamp the plate. At this time, the right roller shaft rises to play a positioning role, the roller rotates until the plate supports the right roller, and then the right roller resets, and the roller reverses to return to the zero point to complete the zero point calibration of the plate.

3. Pre-bending operation: The roller is rotated to the position where the arc needs to be rolled, and the left roller rises for pre-bending. During the pre-bending process, the left roller applies appropriate pressure to make the plate begin to bend initially to the first bending angle close to the L shape. After the pre-bending is completed, the left roller is reset.

4. The first arc rolling: the right roller rises to the pre-bending position, and then the counter roller and the right roller rotate at the same time, driving the plate to curl, gradually forming the first bending angle of the L shape, and the right roller is reset after rolling into a semicircle.

5. The second arc rolling: the counter roller continues to rotate to the position where the second arc needs to be rolled, and the left roller rises again, and cooperates with the counter roller to perform the second arc rolling operation, so that the plate forms the second bending angle of the L shape, thereby completing the rolling of the L-shaped special-shaped part.

6. Take out the workpiece: After the rolling is completed, the counter roller rotates to the zero point, the lower roller of the counter roller descends, and then the rolled L-shaped special-shaped part is carefully taken out.
