The bending machine with pre-bending function is mainly the processing process of continuous three-point bending of the sheet material by the bending machine. The winding process of the coiling machine is mainly by pre-bending, centering, winding, and correction. The circle consists of four parts.
1. When the pre-bending sheet is rolled, the two ends of the flat plate will have a length. Since there is no contact with the upper roller, the length is called the remaining straight edge. Therefore, in order to avoid the sheet material coming out of the work rolls of the coiler, the actual remaining straight edge is usually larger than the theoretical value.
Second, when the bending machine is symmetrically bent on the plate, it will be difficult to eliminate because the remaining straight edge of the plate is rounded, which will cause a large weld seam. At this time, it is easy to produce quality and equipment accidents, so the coil is Before the machine is rolled, the sheet edge is pre-bent so that the remaining straight edges can be closer to the theoretical value.
