[0002] With the continuous development of the automotive industry, the demand for automotive parts is increasing. As a key device for producing automotive metal stampings, the importance of stamping dies for automotive parts is becoming increasingly prominent.

[0003] The stamping die punches metal sheets or other materials into parts of the required shape through high-pressure action. It usually consists of two parts: a working die and a guiding die. The working die is responsible for forming the final shape of the part, while the guiding die ensures the correct positioning and movement of the material during the stamping process.

[0004] Regarding the stamping die for automotive parts, the inventor found that at least the following problems in the prior art have not been solved: In the existing stamping die for automotive parts, before stamping the metal sheet, workers need to limit the position of the metal sheet on the working die. After the guiding die stamps the metal sheet on the working die, a ejecting mechanism needs to first eject the stamped part on the die, and then the workers take out the stamped part on the working die. Since the stamping process of automotive parts is very dangerous, the stamping processes of limiting the position and taking out of automotive parts are completed sequentially by workers and cannot be completed synchronously during the stamping process, resulting in low integration degree and low efficiency of stamping automotive parts.

[0023] Furthermore, the unloading mechanism includes a fixed rod 41, which is fixedly connected to the surface of the support platform 11, and the lower surface of the fixed rod 41 is fixedly connected to the diagonal brace 4, and the diagonal brace 4 is fixedly connected to the surface of the base frame 1, and a fixed block 42 is fixedly connected to the surface of the fixed block 42, and a screw rod 43 is rotatably connected to the surface of the fixed block 42, and a second gear 44 is fixedly connected to the surface of the screw rod 43, and a second rack 45 is fixedly connected to the surface of the lifting plate 14, and a movable block 46 is threadedly connected to the surface of the screw rod 43, and a second connecting plate 47 is fixedly connected to the surface of the movable block 46, and a unloading plate 48 is fixedly connected to the surface of the second connecting plate 47.

A guide hole is provided on the surface of the support platform 11, and the connecting rod 24 slides on the guide hole of the support platform 11. The guide rod 21 squeezes the inclined surface of the driving plate 23 during the rising and falling process, and the guide rod 21 drives the connecting rod 24 to slide on the surface of the support platform 11 through the driving plate 23. When the connecting rod 24 can no longer slide on the support platform 11, the connecting rod 24 no longer descends, and the driving plate 23 supports the guide rod 21. During the descent of the support platform 11, since the traction rope 22 has the ability of flexible deformation, the lifting plate 14 will no longer drive the guide rod 21 to descend on the counterweight 2 through the traction rope 22 during the descent.

[0025] Furthermore, a guide hole is provided on the surface of the support block 25, and the movable rod 26 slides on the guide hole of the support block 25. The movable frame 27 is in a "U" shape, and the movable frame 27 slides on the surface of the support block 25 through the movable rod 26. The end of the first spring 28 away from the movable frame 27 is fixedly connected to the support block 25, and the elastic force of the first spring 28 acts on the connecting rod 24 through the movable frame 27. When the driving plate 23 is not subjected to the extrusion force of the guide rod 21, the elastic force of the first spring 28 causes the guide rod 21 to move. 21 drives the driving plate 23 and the connecting rod 24 to slide to the original position through the movable frame 27, and the gear frame 29 and the first gear 210 slide on the surface of the support block 25 following the movable rod 26. The connecting rod 24 drives the gear frame 29 and the first gear 210 to slide on the support block 25 through the movable frame 27 and the movable rod 26. When the first gear 210 can no longer slide, the driving plate 23 and the connecting rod 24 can no longer slide, so that the guide rod 21 is restricted to a certain horizontal height of the counterweight block 2.

[0026] Furthermore, two groups of first racks 212 are provided, the support frame 211 is in an "H" shape, a cross-shaped guide groove is provided on the surface of the support frame 211, one side of the first rack 212 is in a cross shape, the first rack 212 slides on the guide groove of the support frame 211, the first gear 210 engages with the two groups of support frames 211 at the same time, the first rack 212 slides on the support frame 211 through the first gear 210, the first rack 212 drives the clamping rod 213 to slide on the surface of the working mold 16, the first gear 210 will drive the two groups of support frames 211 to slide on the support frame 211 at the same time, when the clamping rod 213 on one group of first racks 212 is against the working mold When the plate on 16 is limited, the first gear 210 will drive the other group of first racks 212 to continue to slide on the support frame 211 by rotating, so that the clamping rod 213 on the other group of first racks 212 also limits the plate, which enables the clamping rod 213 to clamp plates of different shapes on the working mold 16. When the clamping rod 213 clamps the plate, the first rack 212 does not move, the first gear 210 and the movable rod 26 do not slide, and the positions of the driving plate 23 and the connecting rod 24 do not move, the horizontal height of the guide rod 21 does not decrease, and the lifting plate 14 can still continue to descend through the traction rope 22, thereby realizing the self-adaptation of the plate clamping.

[0027] The lifting plate 33 is lifted up by the extension rod 31, and the lifting plate 33 is lifted up by the extension rod 31. The lifting plate 33 is lifted up by the extension rod 31, and the lifting plate 33 is lifted up by the extension rod 31.

[0029] Furthermore, the diagonal brace 4 is inclined, and the diagonal brace 4 supports the fixed rod 41 on the base frame 1, thereby maintaining the stability of the fixed rod 41 on the base frame 1. The second gear 44 and the screw rod 43 rotate synchronously on the fixed block 42, and the second gear 44 and the second rack 45 are meshed with each other. The lifting plate 14 drives the second gear 44 to rotate on the fixed block 42 through the second rack 45, and then the second gear 44 drives the fixed block 42 to rotate on the fixed block 42. A guide groove is provided on the surface of the fixed rod 41 for the second rack 45 to slide on the guide groove of the fixed rod 41, thereby ensuring the stability of the sliding and lifting of the second rack 45. Two groups of second racks 45 are provided, which are symmetrically distributed on the back of the lifting plate 14.

[0030] Furthermore, a threaded hole is opened on the surface of the movable block 46, and the screw rod 43 drives the movable block 46 to slide linearly on the fixed rod 41 by rotation.

The unloading plates 48 and the ejector rod 35 are staggered with each other. The unloading plates 48 push out the sheet metal stamping parts on the working mold 16 during the sliding process, thereby avoiding the contact between the unloading plates 48 and the ejector rod 35. At the same time, a material receiving conveyor belt can be set in front of the working mold 16 to push the sheet metal directly from the surface of the working mold 16 to the material receiving conveyor belt without manual material receiving.

[0031] Working principle: When the guide die 15 is lowered to stamp the auto parts, the guide rod 21 is driven to descend on the counterweight block 2 through the traction rope 22. During the descent, the guide rod 21 squeezes the inclined surface of the driving plate 23, so that the driving plate 23 drives the connecting rod 24 to slide on the surface of the support platform 11. When the guide rod 21 cannot be lowered, the lifting plate 14 will continue to drive the traction rope 22 to descend. At this time, the horizontal height of the guide rod 21 remains unchanged, and the connecting rod 24 drives the movable rod 26 to slide on the support block 25 through the movable frame 27.

The first gear 210 will drive the two groups of first racks 212 to slide on the support rack 211. When the clamping rods 213 on one group of first racks 212 limit the plate on the working mold 16, the first gear 210 will drive the other group of first racks 212 to continue to slide on the support rack 211 by rotating, so that the clamping rods 213 on the other group of first racks 212 also limit the plate, which enables the clamping rods 213 to be on the working mold 16. The lifting plate 14 is used to clamp the plates of the same shape. At the same time, the lifting plate 14 makes the lifting plate 33 on the telescopic rod 31 contact the surface of the bottom frame 1 during the process of descending. The telescopic rod 31 is retracted at this time and squeezes the second spring 32. When the guide mold 15 completes the stamping of the plate on the working mold 16, the lifting plate 14 will drive the telescopic rod 31 to rise. The telescopic rod 31 drives the lifting plate 33 to rise through the second spring 32. The lifting plate 33 drives the multiple groups of ejector rods 35 to slide on the surface of the working mold 16 through the first connecting plate 34, which will move the working mold 16. The sheet on the tool 16 is ejected, and at the same time, the lifting plate 14 will drive the second rack 45 to rise, the second rack 45 drives the second gear 44 to rotate, and the second gear 44 drives the screw rod 43 to rotate on the fixed block 42, and the fixed block 42 drives the movable block 46 to slide on the fixed rod 41 by rotating, and the movable block 46 drives the unloading plate 48 to move through the second connecting plate 47, and the unloading plate 48 pushes out the sheet stamping parts on the surface of the working die 16, thereby completing the unloading, realizing the clamping of the sheet during the stamping process, as well as the ejection and unloading of the sheet.
