Learn about the rolling process of the 1.8 width bending machine.
Now let's take a look at the winding process of 1.8 wide coiler, which is divided into four steps.
1, pre bending. When the plate is rolled, each end of the plate has a length that does not bend because it can not touch the upper roll. It is called the residual straight edge. The minimum force arm that begins to bend the plate is called the theoretical residual straight edge. Its size is related to the structure of the equipment and its bending form (symmetrical bending, asymmetrical bending).
2, alignment. The purpose of the alignment is to make the workpiece busbar parallel to the roller shaft to prevent twisting.
3. Coil. Rolling is the main process of product forming. It is divided into one feed and multiple feed. Multiple feed is often used in rolling thick plate. Feed times depend on process constraints (e.g. maximum allowable deformation in cold rolls) and equipment constraints (e.g. non-skid conditions and power conditions). When the amount of cold recoiling is remarkable, a certain amount of excess volume must be added.

4, straighten the circle. The purpose of straightening circles is to ensure uniform curvature of the entire circle and ensure product quality as far as possible. The general straightening process consists of three steps:
(1) Loading: Adjust the work roll to the position of the required maximum correction curvature according to experience or calculation.
(2) Rolling round: roll the drum under the rectified curvature for 1-2 turns, so that the curvature of the whole roll is uniform.
(3) unloading: gradually unloading the load, so that the workpiece in the gradual reduction of the correction load rolling many times.
