[0001] The utility model belongs to the technical field of automobile crossbeam stamping, in particular to a stamping die for a floor crossbeam in an automobile. Background Art

[0002] A stamping die is a special tool used for metal stamping processing. The stamping die plays a vital role in the stamping process. It applies pressure to the metal sheet to cause it to undergo plastic deformation, thereby obtaining parts of the desired shape and size. The structure of the stamping die is usually composed of an upper die base, a lower die base, a punch, a die, a guide pin, a guide sleeve, a stripper plate, a pad and other components. The punch and die are the working parts of the stamping die, which are used to stamp metal sheets. The shape and size of the punch and die determine the shape and size of the part.

[0003] When stamping the bottom plate crossbeam plate, after the plate is formed, due to extrusion, the bottom plate crossbeam plate is embedded in the mold, and the staff needs to manually lift it or use tools such as screwdrivers to lift the plate. When manually lifting it, the sharp edges of the plate can easily scratch the hands, and using tools such as screwdrivers to lift it can easily cause scratches on the surface of the plate. Utility Model Content

[0004] In order to solve the problem that after the plate is formed, the bottom plate crossbeam plate is embedded in the mold due to extrusion, and the staff needs to manually lift it or use tools such as screwdrivers to lift the plate. When manually lifting it, the sharp edges of the plate are easy to scratch the hands, and using tools such as screwdrivers to lift it can easily cause scratches on the surface of the plate, the purpose of this utility model is to provide a floor crossbeam stamping die for automobiles.

[0005] To achieve the above-mentioned purpose, the utility model proposes a stamping die for a floor crossbeam in an automobile, comprising a base plate, the upper surface of which is fixedly connected to two support plates, a base is arranged between the support plates, the upper surface of the base is fixedly connected to a lower die, an annular groove is provided on the base, a sliding ring is placed in the annular groove, the inner wall of the sliding ring is close to the outer side of the lower die, a driving assembly is provided on the base, a lifting mechanism is installed on the upper surfaces of the two support plates, an upper die is installed below the lifting mechanism, and the upper die is located above the lower die.

[0006] In one example, a pallet is fixedly connected between the two support plates, the lower mold is located above the pallet, and the support plate is rotatably connected to the base.

[0007] In one example, opposite sides of the two support plates are fixedly connected to a fixing seat, the fixing seat is rotatably connected to a rotating rod, and the rotating rod is fixedly connected to the base.

[0008] In one example, one side of one of the support plates is fixedly connected to a first servo motor, and a main shaft of the first servo motor is fixedly connected to the rotating rod.

[0009] In one example, a conveyor belt is installed on the upper surface of the base plate between two support plates.

[0010] In one example, the drive assembly includes a second servo motor, which is fixedly connected to the base. The main shaft of the second servo motor is fixedly connected to a threaded rod, which is threadedly connected to a sliding ring. The lower surface of the base is fixedly connected to a vertical rod, which passes through the sliding ring and is slidably connected to the sliding ring.

[0011] In one example, the upper ends of the vertical rod and the threaded rod are fixedly connected to the limiting plate.

[0012] The automobile floor beam stamping die proposed by the utility model can bring the following beneficial effects:

[0013] First, by setting a sliding ring, the beam plate is placed on the lower mold. The lifting mechanism has a built-in hydraulic rod, which pushes the upper mold down to extrude the beam plate. After the beam plate is extruded, the sliding ring rises and pushes the plate that is in contact with the lower mold to loosen and separate from the lower mold. The staff does not need to manually lift it up, which prevents the sharp edges of the plate from cutting their palms. At the same time, there is no need to use tools such as screwdrivers to lift the plate, which avoids scratches on the plate surface.

[0014] Secondly, by setting a rotating rod, after the stamping is completed, the first servo motor drives the rotating rod to rotate, flipping the lower mold to the other side, so that the plate is downward. After the sliding ring pushes the plate to loosen, the plate falls under the action of gravity and detaches from the lower mold. No staff participation is required, which is safer and more labor-saving. After the plate falls, it falls on the conveyor belt and is transported to one side by the conveyor belt, which is convenient for subsequent processing such as trimming and is more convenient to use.
