Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a side cutting mechanism for a metal stamping die. Background Art

[0002] A stamping die is a special process equipment that processes materials into parts in cold stamping processing, called a cold stamping die. Stamping is a metal processing method in which, at room temperature, a die installed on a press applies pressure to a material to cause separation or plastic deformation, thereby obtaining the required parts.

[0003] For an existing side cutting mechanism, such as a side cutting mechanism for a metal stamping die disclosed in the utility model patent with the application number 202220312754.0, its main structure includes a bottom plate. Uniformly distributed guide rails are fixedly connected to the top of the bottom plate. A top plate is arranged on the top of the bottom plate. The top ends of the guide rails are fixedly connected to the bottom of the top plate. A hydraulic cylinder is fixedly installed on the top of the top plate. The bottom end of the hydraulic cylinder penetrates and extends to the bottom of the top plate. The bottom end of the hydraulic cylinder is fixedly connected to a floating plate. The guide rails are slidably connected to the inner wall of the floating plate. A stamping seat is fixedly connected to the bottom of the floating plate. When in use, an operator places a metal plate on the top of the bearing seat, and then controls the hydraulic cylinder to be powered on to work. After the hydraulic power is turned on, the floating plate fixedly connected thereto moves downward. The floating plate vertically moves downward along the direction of the guide rails, and the stamping seat moves downward until the two sides of the metal plate are bent. When it is necessary to perform side cutting on the metal plate, the operator controls the electric push rod to be powered on to work. After the electric push rod is powered on, the bearing plate fixedly connected thereto moves. As the electric push rod continuously works, the distance between the cutting tool and the metal plate gradually shortens. Then, the operator controls the dust suction mechanism to be powered on to work, and the debris is sucked into the installation box through the suction holes for collection.

[0004] However, in the existing side cutting mechanism, the cutting tool is easily worn after multiple cuts, and the downtime for changing the tool wastes a lot of time. Manual blanking is still required after stamping side cutting, which is very dangerous and may cause harm to the workers' bodies. Summary of the Utility Model
