  The following 4 flattening bending solutions. 1. The traditional way is to change the press brake hemming dies . 2. The Spring Hemming die is used. There is no need to change the mold during the whole process. The top notch is folded and the sharp corner is bent, and the second side bounces the part to flatten the edge in one go. 3. Pneumatic hemming di e , it cancels the second spring design and uses a pneumatic device instead. It can be opened when it needs to be flattened, which is more scientific. 4. The U-shaped lower die cooperates with the integrated upper die for bending and flattening, adjusting the bending stroke to complete job GOLIN Press brake hemming dies with spring for flatten, we can change the v opening according to the customer's bending thickness.  accept customized.

  The relationship between the notch width of the lower die of the CNC bending machine mold and the plate thickness is a question that many metal processing manufacturers will ask. Now the recognized calculation formula in the market is: V groove width = plate thickness *8. This is a common calculation formula in the market, but it also hides a disadvantage. For workpieces that require precision, is this formula still applicable? The result is that it does not completely match. Because this formula is only suitable for precision bending, not for suspended bending and close bending. At the same time, the ratio of the width of the lower die groove of the bending machine to the plate thickness required by different materials is not necessarily the same. According to the data summarized according to market requirements, the plate thickness t: o~3mm plate, the notch width of the lower die of the bending machine V=plate thickness t*6, precision bending can be narrowed to...
