Description

Technical Field

[0001] The utility model relates to the field of bending machines, in particular to a bending machine which can be fixed in multiple directions. Background Art

[0002] A bending machine, also known as a press brake, is a machine that can bend thin plates. Its structure mainly includes an extension platform, a workbench and a clamping assembly. The workbench, as the main bending workpiece, is composed of a base and a pressure plate. The pressure plate and the base interact to bend the thin plate. At this time, the extension platform and the clamping assembly are used to position the thin plate and clamp the thin plate during the bending process. The traditional clamping assembly only realizes the depth positioning of the thin plate entering the workbench, and cannot adjust and position the left and right position of the thin plate. This can easily cause the thin plate to deviate in the left and right directions during the bending process. Therefore, a bending machine that can fix the thin plate in multiple directions is needed.
