Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a sheet metal punching and blanking device. Background Technology

[0002] In recent years, with the increasingly fierce competition in the automotive market, major automakers have focused their research and development on the body panels and related stamped parts (hereinafter collectively referred to as parts) of the vehicle itself. Existing sheet metal part molds have simple structures, requiring manual stripping of sheet metal parts, followed by re-fixing and processing of the stripped parts. The entire process is cumbersome and complex, reducing processing efficiency. Patent No. CN202220870870.4 discloses a stamping and blanking die for automotive sheet metal parts. The device includes a base, a fixed mold fixed to the top of the base, a top plate fixed to the top of the base via a bracket, a hydraulic cylinder fixed to the bottom of the top plate, and a stamping die fixed to the output end of the hydraulic cylinder. A connecting plate is fixed to the top of the stamping die via a hydraulic rod, and a punching machine is fixed to the bottom of the connecting plate. A cutting machine is fixed to both sides of the connecting plate via connecting frames. The stamping die has drill holes adapted to the punching machine. A cylinder corresponding to the drill holes is fixed to the bottom of the base, and a moving block is fixed to the output end of the cylinder. The cylinder 11 drives the moving block 12 to move upward, and the processed sheet metal part is pushed out and unloaded through the moving block 12. After the sheet metal part is unloaded, the worker still needs to manually remove the workpiece, which is dangerous. Therefore, this utility model proposes a sheet metal part punching and blanking device. Utility Model Content

[0003] This utility model achieves the above-mentioned objective through the following technical solution: a sheet metal punching and blanking device, including a frame, a punching mechanism on the frame, a material belt traction conveyor and a blanking mechanism on both sides of the punching mechanism, the punching mechanism including an upper die, a lower die and cavities and modules respectively provided on the lower die and the upper die, the lower die and the upper die are both connected to a lifting cylinder, a cutter is provided at one end of the upper die and the lower die near the blanking mechanism, the blanking mechanism includes two parallel support rods, one end of the support rods is rotatably connected to the side of the lower die by a pin, and a drive mechanism for driving the support rods to rotate is provided on the frame.

[0004] Preferably, the driving mechanism includes an arc-shaped rod with one end fixed to the lower end face of the support rod with the pin as the center. The inner side of the arc-shaped rod is provided with a first rack along its periphery. Both sides of the lower mold side are provided with side plates. A gear shaft that meshes with the first rack is rotatably connected between the two side plates. A vertical rod is fixed on the frame. A second rack that meshes with the gear shaft is provided on one side of the vertical rod.

[0005] Preferably, a receiving slide plate is provided below the other end of the support rod.

[0006] Preferably, the vertical rod is located on the side of the gear shaft closer to the lower mold.

[0007] The beneficial effects of this utility model are as follows: Under the drive of the drive mechanism, the support rod can be rotated to a horizontal position when the upper and lower dies are close to each other for stamping, and rotated to a downward tilt position when the lower and upper dies are separated. When the lower and upper dies are stamping, the previously stamped workpiece will be cut and placed on the support rod in a horizontal position. When the lower and upper dies are separated, the support rod tilts downward and the workpiece slides down along the support rod, thereby realizing automatic material unloading and avoiding the disadvantage of high risk of manual material handling in the prior art.

[0011] The present invention will be further described in detail below with reference to specific embodiments.

[0012] Example:

[0013] like Figure 1 As shown, a sheet metal punching and blanking device of this utility model includes a frame, on which a punching mechanism is provided. A material belt traction conveyor 1 and a blanking mechanism are respectively provided on both sides of the punching mechanism. The punching mechanism includes an upper die 2, a lower die 3, and cavities 4 and modules 5 respectively provided on the lower die 3 and the upper die 2. Both the lower die 3 and the upper die 2 are connected to lifting cylinders. A cutter 6 is provided at one end of the upper die 2 and the lower die 3 near the blanking mechanism. The blanking mechanism includes two parallel support rods 7. One end of the support rod 7 is rotatably connected to the side of the lower die 3 by a pin. A drive mechanism for driving the support rods 7 to rotate is provided on the frame.

[0014] The driving mechanism includes an arc-shaped rod 8 fixed at one end to the lower end face of the support rod 7 with the pin as the center. The inner side of the arc-shaped rod 8 is provided with a first rack 9 along its periphery. Both sides of the lower mold 3 are provided with side plates. A gear shaft 10 that meshes with the first rack 9 is rotatably connected between the two side plates. A vertical rod 11 is fixed on the frame. A second rack 12 that meshes with the gear shaft 10 is provided on one side of the vertical rod 11.

[0015] The other end of the support rod 7 is provided with a receiving slide plate 13.

[0016] The vertical rod 11 is located on the side of the gear shaft 10 near the lower mold 3.

[0017] The process of this utility model is as follows: In the initial state, the upper mold 2 and the lower mold 3 are separated, the support rod 7 is tilted downward, the traction conveyor 1 transports the material belt between the upper mold 2 and the lower mold 3, the lifting cylinder drives the upper mold 2 and the lower mold 3 to move closer to each other and stamp the workpiece. When the lower mold 3 moves upward, the gear shaft 10 rolls counterclockwise along the second rack 12, thereby driving the arc rod 8 to rotate counterclockwise. When the workpiece stamping is completed, the support rod 7 just rotates to the horizontal position. The upper mold 2 and the lower mold 3 are separated under the drive of the lifting cylinder, the support rod 7 is reset, the traction conveyor 1 continues to feed material, and the stamped workpiece comes to the top of the support rod 7. When stamping the next workpiece, the cutter 6 cuts the previously stamped workpiece from the material belt. The cut workpiece falls on the support rod 7, which is now horizontal. When the upper mold 2 and the lower mold 3 are separated, the cut workpiece slides down the support rod 7 onto the receiving slide plate 13.

[0018] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
