Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a bending machine with a clamping structure. Background Art

[0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench consists of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base consists of a base shell, a coil and a cover plate. The coil is placed in the depression of the base shell, and the top of the depression is covered with a cover plate. When in use, the coil is energized by a wire, and after energization, an attractive force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and can process workpieces with side walls, and the operation is also very simple.

[0003] At present, when most of the existing hydraulic bending machines bend the spokes, the spokes are first placed on the bending disk, and then the top block cylinder is prompted to contact the spokes through the rotation of the bending disk to bend the spokes. However, the diameters of most spokes are not fixed. When the diameter of the spokes is large or small, the spokes will be separated from the bending disk during bending due to the lack of a limit adjustment structure for the spokes.
