Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal bending, and in particular relates to a bending device used for metal processing. Background Art

[0002] Sheet metal fabrication is a crucial process in the formation of sheet metal products. It often involves processing sheet metal, such as bending, cutting, and welding. Sheet metal bending is particularly important. Bending is the process of changing the angle of a sheet or component, such as bending a sheet into a V or U shape.

[0003] Generally speaking, there are two methods for sheet metal bending: one is die bending, which is used for complex, small, and high-volume sheet metal structures; the other is bending with a press brake, which is used to process larger structures or smaller production volumes. The working principle of a sheet metal bending machine is as follows: when bending sheet metal, the sheet metal is placed directly on the base of the press brake. A notch is opened at a certain angle on the top of the base. When the electric push rod drives the pressure plate downward, the sheet metal on the base is bent. To improve work efficiency, most production lines are equipped with dual stations for bending.

[0004] However, in the actual metal processing process, although the efficiency of the sheet metal bending machine can be improved by setting up a double station, the notch angle on the base is fixed, and the shape of the bent sheet metal is also fixed. When a sheet metal of a different shape needs to be bent, the base needs to be replaced. The replacement process is relatively cumbersome and greatly reduces the bending efficiency. Therefore, it is urgent to design a bending device for metal processing to solve the above problems. Utility Model Content
