Description

Technical Field

[0001] The utility model relates to a steel plate bending tool, in particular to a steel plate bending tool, and belongs to the technical field of steel plate bending. Background Art

[0002] In the production process of steel plates, it is often necessary to use a steel plate bending machine to process the steel plates. The bending machine clamps the steel plate through a mold and moves or deflects it under the action of a hydraulic cylinder, thereby bending the steel plate into various shapes. At present, the interface steel plate needs to be bent during production, but when the existing interface steel plate bending device is in use, the middle part of the steel plate will be deformed due to the force of the bending part, affecting the use of the steel plate. The existing patent is an interface steel plate bending tool, and the patent authorization number is CN 214184723 U. The length of the protruding steel plate on the U-shaped operating table can be adjusted, which is convenient for bending the interfaces of steel plates of different lengths. The expansion and contraction of the spring is used to buffer the pressure plate to avoid deformation of the top side of the steel plate under the action of force when bending at the interface of the steel plate, thereby maintaining the flatness of the steel plate.

[0003] However, the patent authorization number is CN 214184723 U. It is impossible to adjust the bending angle of the steel plate. Since the steel plate needs to be bent into different angles during the processing to meet the installation requirements, the applicability is low. Therefore, we propose a steel plate bending tool.
