[0021] Depend on Figures 1 to 5 The present invention discloses a metal sheet stamping forming device, comprising a stamping frame 1, a hydraulic rod 2 inserted at the middle of the top of the stamping frame 1, an upper stamping die 3 fixedly mounted at the bottom of the hydraulic rod 2, an operation panel 4 fixedly mounted at the top of one side of the stamping frame 1, a stamping die groove 5 matching the upper stamping die 3 opened at the middle of the interior of the stamping frame 1, a hydraulic rod 6 fixedly mounted at the middle of the bottom of the interior of the stamping frame 1, a lower stamping die 7 slidably connected to the stamping die groove 5 fixedly mounted at the top of the hydraulic rod 6, limit pressing components 8 provided on both sides of the interior of the stamping frame 1, and a sheet metal traction component 9 fixedly mounted at the middle of the side of the stamping frame 1 away from the operation panel 4.

[0022] Hydraulic rod 2 can drive the upper stamping die 3 to move up and down, and hydraulic rod 6 can drive the lower stamping die 7 to move up and down. During stamping, the lower stamping die 7 moves to the bottom of the stamping die groove 5, and the upper stamping die 3 presses down to punch the metal sheet into a metal block of standard size. At this time, the metal block is located inside the stamping die groove 5. Then, the internal components of the upper stamping die 3 are rotated 180 degrees and the stamping operation is performed again, so that the metal block can be stamped into a metal part of standard shape. After stamping, the part is located at the top of the lower stamping die 7. Then, the lower stamping die 7 is moved down by hydraulic rod 6, so that the lower stamping die 7 is separated from the stamping die groove 5, which makes it easier to unload the stamped part.

[0023] The upper stamping die 3 is composed of a U-shaped frame 10, a rotating shaft 11, a die base 12, a punching die head 13, a forming die head 14, a worm gear 15, a servo motor 16, and a worm 17. The U-shaped frame 10 is fixedly connected to the bottom end of the hydraulic rod 2. The rotating shaft 11 is rotatably connected to the inside of the U-shaped frame 10.

The punching die head 13 and the forming die head 14 are respectively fixedly connected to the two ends of the die base 12. The worm gear 15 is fixedly connected to one end of the rotating shaft 11. The servo motor 16 is fixedly connected to one end of the U-shaped frame 10. The worm 17 is fixedly connected to the output shaft of the servo motor 16 and meshes with the worm gear 15.

[0024] The U-shaped frame 10 provides support, the punching die 13 can punch large-size plates, and the forming die 14 can stamp the standard-sized metal plate formed after punching. When switching between the punching die 13 and the forming die 14, the servo motor 16 drives the worm gear 17 to rotate, the worm gear 17 drives the worm wheel 15 to rotate, and the worm wheel 15 drives the die base 12 to rotate.

[0027] The sheet metal traction assembly 9 consists of a first support frame 21, a second support frame 22, a second servo motor 23, a traction roller 24, and a pressure roller 25.

The pressure roller 25 is rotatably connected to the top end between the first support frame 21 and the second support frame 22.

[0028] During continuous stamping, large-sized sheet metal needs to be continuously moved. At this time, servo motor 23 drives traction roller 24 to rotate. Traction roller 24 and pressure roller 25 press the sheet metal together, thereby realizing continuous traction of the sheet metal.

[0029] The top of the first support frame 21 and the second support frame 22 are both slidably provided with sliders 26, and the pressure roller 25 is rotatably connected between the two sliders 26.
