Technical Field

[0002] The flexible bending center is a bending device for bending sheets. Through the cooperation of two folding knives, a pressing die and a bending tool holder, the end of the sheet can be bent to a specified angle according to tool requirements. Then, the above operations are repeated and the sheet is adjusted to achieve the purpose of bending the sheet.

In order to further improve the accuracy and stability of the plate bending without increasing the cost, so as to further improve the processing efficiency of the plate, we propose a flexible bending center for folding long plates.
