Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to an adjusting device which is convenient for adjusting the processing angle of a bending machine. Background Art

[0002] Bending machines are common equipment for processing parts. They mainly use the cooperation between the pressure head and the support to process the bending parts of the parts. For some parts that need to process multiple bending parts, it is often necessary to move the parts so that different bending parts can be moved to the processing parts. It is inconvenient to adjust the position of the processing parts. During processing, the repeated positioning effect of the processing parts is poor, which affects the positioning effect of the processing parts. In addition, when the parts are bent, when the parts to be processed are moved, the parts are easy to offset, which affects the positioning accuracy of the processing parts. Utility Model Content
