The four-roller plate rolling machine provides a variety of curved workpieces, and the user can select the most preferred one. The following is for reference only, as shown.
A. Operate the roller so that the upper and lower distances are slightly larger than the plate thickness. Then operate the paper feed side roller so that the side roller up and down rollers are maintained at the same height. Finally, operate the other side to position the side roller between the top and bottom rollers.
B Feeding: horizontally feed the plate to make plate end touch with ventro-side roller wholly, then low the side roller to the original position.
C firmly grip the plate and begin pre-bending.
D Use the static side roller to pre-bend the other side of the plate, after completing the pre-curved left side, lower the rear roller to the original position; then operate the upper roller to bend the plate to the correct position shown in the figure, and then stop on the upper roller Finally, operate the other side of the longitudinal side roller bending plate.
E: Bending: Adjust the center and rear drums to the correct position and operate the upper drum for major bending.
F-forming bending: The intermediate roller and the rear roller are adjusted to an appropriate position, and the upper roller operates to form a bend.
G. Remove the workpiece: After completing the entire bending, lower the lower roller to the lowest position, then gradually lower the workpiece, place the rollers on both sides in the correct position, rotate the head, lift the workpiece, and then remember to keep the same with the upper roller . Eject the workpiece.
