Technical Field

[0001] The utility model relates to the technical field of bending machine positioning, in particular to a hydraulic plate bending machine positioning tool. Background Art

[0002] A bending machine is a mechanical device used to bend metal sheets, pipes, etc. It can bend flat or rolled materials into the desired shape, such as angle iron, U-shaped groove, box-shaped structure, etc. through a series of pressurization and bending operations. The bending machine is widely used in the metal processing and manufacturing industries for the production of components, parts and products.

[0003] When the existing equipment is in use, in order to ensure that the workpiece does not tilt during bending, the workpiece is usually positioned by the worker holding one end of the workpiece. This operation is somewhat dangerous. If the operation is improper, it is easy to cause harm to the worker. The processed part of the workpiece is also manually adjusted by the worker, which is very cumbersome and not accurate enough. Utility Model Content

By setting a positioning mechanism, the workpiece is placed on the roller 4, and the first motor 17 is started. Since the threads on both sides of the bidirectional screw 9 are in opposite directions, the two positioning plates 5 are moved in opposite directions at the same time through the threaded connection with the two positioning plates 5 and the cooperation of the limiting rod 10 until the rotating rods 6 on both sides contact the workpiece, and the first motor 17 is turned off. At this time, the positioning plate 5 drives the roller 8 to squeeze and limit the workpiece through the rebound force of the spring 12, so as to prevent the workpiece from tilting and deviating during processing, and the workpiece is still limited during the bending process, which further strengthens the limiting effect, thereby solving the problem that the positioning of the workpiece needs to be done manually.

[0036] Reference Figure 1-6 The feeding mechanism includes a rotating rod 6, an extrusion plate 7 and a roller 8. The rotating rod 6 is rotatably installed inside the positioning plate 5, the extrusion plate 7 is slidably installed on the opposite side of the two positioning plates 5, and the roller 8 is rotatably installed at the bottom of the extrusion plate 7.
