Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of automotive part processing, and particularly relates to a stamping die for automotive parts. Background Art
[0002] In the field of automotive manufacturing, stamping dies are one of the commonly used devices for producing automotive parts. By applying high pressure to a metal sheet through the die, plastic deformation is caused to obtain the required part shape. After the automotive part is shaped, it is necessary to demold the automotive part from the die. Currently, demolding of automotive part stamping dies mostly uses a robotic arm for assistance. After the upper die is lifted, the robotic arm enters the die cavity, grabs the part through a suction cup or gripper, and moves the part out of the die and places it on a conveyor belt or a stacking area. Then the robotic arm resets and waits for the next stamping cycle. However, the action cycle of the robotic arm (such as moving, grabbing, placing) increases the single-piece production time, making it difficult to match the high-speed stamping rhythm, which not only reduces production efficiency but also increases equipment costs and operation complexity.

Specific Embodiments
[0024] To better understand the technical content of the present invention, specific embodiments are provided below, and the present invention will be further described in conjunction with the accompanying drawings.
[0025] Embodiment 1
[0026] Refer to Figures 1 to 7, an automotive part stamping die provided by the present invention includes a stamping table 1, an upper stamping die 5 and a lower stamping die 6. A fixing frame 11 is connected to the stamping table 1, and a hydraulic press 12 is installed on the fixing frame 11. The fixing frame 11 serves to fix the hydraulic press 12. The output end of the hydraulic press 12 is connected to the upper stamping die 5. The lower stamping die 6 is disposed on the stamping table 1. An elastic template 8 is slidably connected within the lower stamping die 6. The upper stamping die 5 can be moved up and down by the hydraulic press 12 to cooperate with the lower stamping die 6 to manufacture automotive parts. After the automotive parts are pressed, when the upper stamping die 5 disengages from the lower stamping die 6, the elastic template 8 moves upward to push the automotive parts out of the lower stamping die 6. Guide rails 13 are respectively connected to both sides of the stamping table 1, and connection mechanisms 14 are respectively connected to both sides of the lower stamping die 6. The connection mechanisms 14 are slidably connected to the guide rails 13. The connection mechanisms 14 are connected to the stamping table 1 through first elastic members 24. Guide shafts 25 and lifting frames 26 are respectively connected to both sides of the upper stamping die 5. The lifting frames 26 are used to lift the lower stamping die 6. Two guide rack bars 3432 are slidably connected to the fixing frame 11. A second elastic member 35 is disposed between the guide rack bars 3432 and the fixing frame 11. A guide groove is provided at the top of the fixing frame 11. The second elastic member 35 is disposed within the guide groove. Both ends of the second elastic member 35 are respectively connected to the guide groove and the guide rack bars 3432. The first elastic member 24 and the second elastic member 35 are both compression springs. The guide rack bars 3432 cooperate with the connection mechanisms 14 to cause the lower stamping die 6 to flip. The flipping angle of the lower stamping die 6 is less than or equal to 90 degrees. The guide shafts 25 cooperate with the guide rack bars 3432 to cause the guide rack bars 3432 to separate from the connection mechanisms 14. When pressing automotive parts, the lifting frames 26 are connected to the connection mechanisms 14. After the automotive parts are pressed, the hydraulic press 12 drives the upper stamping die 5, the guide shafts 25 and the lifting frames 26 to move upward. Thus, the lifting frames 26 drive the lower stamping die 6 and the connection mechanisms 14 to move upward. When the connection mechanisms 14 contact the guide rack bars 3432, under the action of the guide rack bars 3432, the connection mechanisms 14 drive the lower stamping die 6 to flip. After the connection mechanisms 14 rotate to a certain angle, the hydraulic press 12 drives the upper stamping die 5, the guide shafts 25 and the lifting frames 26 to continue to move upward, causing the lifting frames 26 to separate from the connection mechanisms 14. The elastic template 8 moves upward to demold and output the automotive parts within the lower stamping die 6. Under the cooperation of the guide shafts 25 and the guide rack bars 3432, the guide rack bars 3432 are pushed to move on the fixing frame 11, and the guide rack bars 3432 separate from the connection mechanisms 14. Under the action of the first elastic member 24, the lower stamping die 6 moves downward to reset. Among them, the force required to compress the second elastic member 35 is greater than the force exerted on the guide rack bars 3432 by the connection mechanisms 14 driving the lower stamping die 6 to flip.
[0027] The connecting mechanism 14 includes a connecting shaft 15, a connecting seat 16, a rotating shaft 17, a gear 18 and a torsion spring 19. The connecting seat 16 is slidably connected to the guide rail 13. When the die 6 and the connecting mechanism 14 are lifted by the lifting frame 26, the guide rail 13 plays a guiding role. The connecting seat 16 is connected to the stamping table 1 through a first elastic member 24. When the guiding rack 3432 is separated from the connecting mechanism 14, the first elastic member 24 resets, causing the lower die 6 to move downward and reset, facilitating continuous die stamping of automotive parts. The connecting seat 16 is rotatably connected to the rotating shaft 17. The free end of the rotating shaft 17 is connected to the gear 18. The torsion spring 19 is sleeved outside the rotating shaft 17. The two ends of the torsion spring 19 are respectively connected to the connecting seat 16 and the gear 18. The gear 18 is connected to the lower die 6 through the connecting shaft 15. When the connecting mechanism 14 moves upward, the gear 18 meshes with the guiding rack 3432, driving the rotating shaft 17 and the connecting shaft 15 to rotate, thereby driving the lower die 6 to flip. When the upper die 5 drives the guiding shaft 25 to continuously move upward, the guiding shaft 25 acts on the guiding rack 3432, and the guiding rack 3432 moves away from the gear 18. The guiding rack 3432 is separated from the gear 18. Under the action of the torsion spring 19, the lower die 6 is driven by the rotating shaft 17 to flip to a horizontal state, and the first elastic member 24 resets, pulling the lower die 6 downward.
[0028] Wherein, a connecting groove 20 is provided on the connecting shaft 15. The connecting groove 20 is an arc-shaped connecting groove 20. The two ends of the connecting groove 20 are respectively connected to a slot opening 21 and a separation slot opening 22. The slot opening and the separation slot opening 22 are respectively connected to the connecting groove 20. Guiding surfaces 23 are provided at both ends of the access slot opening 21.
[0029] The lifting frame 26 includes a lifting rod 27 and an elastic telescopic rod 28. The two ends of the lifting rod 27 are respectively connected to the upper die 5 and the elastic telescopic rod 28. The elastic telescopic rod 28 cooperates with the connecting groove 20. The elastic telescopic rod 28 includes a sleeve rod 29 and two inner rods 30. The two inner rods 30 are respectively slidably connected to both ends of the sleeve rod 29. A third compression spring 31 is provided between the inner rod 30 and the sleeve rod 29.
[0030] When the upper die 5 drives the lifting frame 26 to move downward, the inner rod 30 of the elastic telescopic rod 28 contacts the guiding surface 23 of the access slot opening 21, and the inner rod 30 contracts. The lifting frame 26 continues to move downward, and the inner rod 30 of the elastic telescopic rod 28 enters the connecting groove 20. The elastic telescopic rod 28 is stuck in the connecting groove 20. When the lifting frame 26 rises, it can drive the connecting mechanism 14 to move upward. When the connecting mechanism 14 rotates, the inner rod 30 rotates along the connecting groove 20. When the inner rod 30 slides to the separation slot opening 22, the inner rod 30 of the elastic telescopic rod 28 is separated from the connecting groove 20.
[0031] The elastic template 8 includes a template 8 and a number of fourth pressure springs 9. Both ends of the number of fourth pressure springs 9 are respectively connected to the template 8 and the lower punch die 6. A limiting ring 10 for defining the position of the template 8 is provided in the lower die. The limiting ring 10 defines the lowest position for the template 8 to move downward, facilitating the downward movement of the upper punch die 5 to press the automotive parts. When the upper punch die 5 moves upward, the pressure on the template 8 is lost, and the fourth pressure springs 9 reset to push out the automotive parts pressed in the lower punch die 6.
[0032] The guiding rack bar 3432 includes a guiding rod 33 and a rack bar 34. The rack bar 34 is connected to the guiding rod 33. The end of the guiding rod 33 is slidably connected to the fixed frame 11. The guiding rod 33 cooperates with the guiding shaft 25. When the guiding shaft 25 moves upward, the guiding shaft 25 acts on the guiding rod 33, causing the guiding rod 33 to drive the rack bar 34 to move away from the gear 18. The rack bar 34 meshes with the gear 18 of the connecting structure.
[0033] A chute 36 is provided in the guide rail 13, and the first elastic member 24 is arranged in the chute 36.
[0034] During use, the automotive part material is placed in the lower punch die 6. The hydraulic press 12 drives the upper punch die 5 and the lifting frame 26 to move downward. The upper punch die 5 presses the automotive part material in the lower punch die 6. The elastic telescopic rod 28 of the lifting frame 26 is snapped into the connecting groove 20. After the automotive parts are pressed, the hydraulic press 12 drives the upper punch die 5 and the lifting frame 26 to move upward. The lifting frame 26 drives the connecting mechanism 14 and the lower punch die 6 to move upward. When the gear 18 of the connecting mechanism 14 meshes with the rack bar 34 of the guiding rack bar 3432, under the cooperation of the rack bar 34 and the gear 18, the rotating shaft 17 and the connecting shaft 15 rotate, driving the lower punch die 6 to flip, and the inner rod 30 of the elastic telescopic rod 28 rotates along the connecting groove 20. The inner rod 30 slides to the separation notch 22. The hydraulic press 12 drives the upper punch die 5, the guiding shaft 25 and the lifting frame 26 to continue moving upward. The inner rod 30 of the elastic telescopic rod 28 is separated from the connecting groove 20 (i.e., the lifting frame 26 is separated from the connecting mechanism 14). The upper punch die 5 moves away from the lower punch die 6. The fourth pressure springs 9 push the template 8 to demold the automotive parts pressed in the lower punch die 6, output the automotive parts. The guiding shaft 25 acts on the guiding rod 33, pushing the guiding rod 33 to move away from the rack bar 34. The gear 18 is separated from the rack bar 34. Under the action of the torsion spring 19, the rotating shaft 17 drives the lower punch die 6 to rotate and reset to the horizontal state. The first elastic member 24 contracts, pulling the lower punch die 6 to move downward and reset.

In the initial state, the lower die 6 is located in the mounting groove 3 to position the lower die 6 so that the upper die 5 and the lower die 6 are aligned with each other.
[0037] A guide plate 4 is provided on one side of the mounting groove 3, and a conveyor belt 37 is arranged below the guide plate 4. The automotive parts output by driving the lower die 6 to flip by the connecting mechanism 14 are conveyed through the conveyor.
