Description

Technical Field

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

[0002] A press brake is a common metal processing equipment, mainly used to bend metal sheets into the desired shape. A press brake is usually composed of a body, a workbench, a tool holder, an upper die, a lower die, a transmission system and a control system. The press brake can complete the bending operation of the sheet through the movement of the upper and lower dies.

[0003] During the bending process of the existing bending machine, the edge of the metal plate will bend, so it cannot be aligned and fixed. The metal plate can only be fixed by the worker holding the metal plate.

In addition, the hand-held fixing method is less safe and can easily scratch the worker's hand during the bending process of the metal plate. When the worker makes an operational error, he may be cut by the folding knife, which endangers the worker's life safety. Utility Model Content
