Technical Field

[0001] The utility model relates to a stamping die for a lightweight vehicle frame assembly, belonging to the technical field of stamping dies. Background Technique

[0002] In the prior art, as disclosed in the utility model with the application number 202222786476.5, a stamping die for forming a vehicle frame tube beam is disclosed. In order to solve the problem that common stamping dies can only support one workpiece to be stamped and formed at a time, which greatly reduces the overall production efficiency, through the setting of a moving conveying component, a driving motor drives a gear to rotate, and the gear drives a conveying plate to slide in a chute through a rack, so that the lower die on the conveying plate moves and adjusts to a position corresponding to the upper die, so as to stamp multiple groups of tube beams, improving the overall production efficiency. Both the upper die and the lower die can be disassembled and assembled, and can be replaced with different shapes according to production requirements.

[0003] The prior art similar to the above application still has deficiencies:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. However, the embodiments of the present utility model are not limited thereto.

[0025] Such as Figures 1-4As shown in the figure, this embodiment provides a stamping die for a lightweight vehicle frame assembly, including a base 1, a conveying plate 2 sliding along the length direction of the base 1, a lower die 3 located at the top of the conveying plate 2 and evenly arranged along the length direction, a U-shaped frame 4 erected at the middle position of the base 1, a hydraulic cylinder 5 installed at the inner top of the U-shaped frame 4, a U-shaped plate 6 located at the output end of the hydraulic cylinder 5 and sliding along the inner side of the U-shaped frame 4, and an upper die 7 installed at the inner bottom of the U-shaped plate 6. Guide blocks 12 are installed at both ends of the inner side of the U-shaped plate 6. Slots 13 are opened at the top of the base 1 below the ends of the U-shaped plate 6. Vertical guide grooves 8 are evenly opened on the side of the conveying plate 2. The guide blocks 12 are slidably arranged inside the vertical guide grooves 8. Inclined guide grooves 9 are inclinedly opened at the bottom ends of the vertical guide grooves 8. A guiding assembly 11 for guiding the guide blocks 12 into the inclined guide grooves 9 is provided at the bottom ends of the inclined guide grooves 9. A horizontal guide groove 10 is horizontally opened at the top of the inner side of the conveying plate 2, and both ends of the horizontal guide groove 10 are communicated with the vertical guide grooves 8 and the inclined guide grooves 9 respectively.

[0026] Overall working principle: When in use, the stamping profiles are evenly placed inside the lower die 3, and then the hydraulic cylinder 5 is started to control the vertical movement of the upper die 7 at the bottom of the U-shaped plate 6. When the upper die 7 moves down and fits with the profiles, at this time, the guide blocks 12 at the inner ends of the U-shaped plate 6 are located at the lowest ends of the vertical guide grooves 8. As the upper die 7 continues to move down, the profiles are stamped. At the same time, the guide blocks 12 move below the vertical guide grooves 8. After stamping is completed, the upper die 7 rises and separates from the profiles. At this time, the guide blocks 12 also rise simultaneously. While the upper die 7 rises and separates from the profiles, the guide blocks 12 enter the inclined guide grooves 9 under the guiding action of the guiding assembly 11. After the upper die 7 rises to the initial position, the guide blocks 12 move along the inclined guide grooves 9 to the top of another group of vertical guide grooves 8 again. The horizontal movement of the conveying plate 2 is automatically controlled to automatically convey the profiles. After the profiles at the tail end are stamped, at this time, after the guide blocks 12 rise to the initial height, they are lifted upward by a certain distance again. The guide blocks 12 enter the horizontal guide grooves 10, the horizontal reset of the conveying plate 2 is controlled, the guide blocks 12 reach the other end of the horizontal guide grooves 10, and then the guide blocks 12 are controlled to move down and enter the vertical guide grooves 8. Repeat the above steps to continuously carry out stamping operations.

[0027] In this embodiment, the guide blocks 12 are cylindrical in shape, and the guide blocks 12 are rotatably connected to the U-shaped plate 6.

[0028] Local working principle: The guide blocks 12 move cyclically between the vertical guide grooves 8, the inclined guide grooves 9 and the horizontal guide grooves 10. The cylindrical guide blocks 12 can reduce wear during the movement process.

[0029] In this embodiment, the guiding component 11 includes an installation groove 14, a guide plate 15, and a first spring 16. An installation groove 14 is formed at the bottom end of the inclined guide groove 9. The guide plate 15 is hingedly installed inside the installation groove 14. The guide plate 15 is parallel to the inclined guide groove 9 and blocks the bottom of the vertical guide groove 8. A first spring 16 is provided between the outer side of the top end of the guide plate 15 and the inner end of the installation groove 14.

[0030] Local working principle: After the upper die 7 moves downward and fits with the profile, at this time, the guiding block 12 fits with the top of the guide plate 15. As the upper die 7 continues to move downward to complete stamping, the guiding block 12 pushes the guide plate 15 away and enters below the vertical guide groove 8. Then, the guide plate 15 resets under the action of the first spring 16 and blocks the vertical guide groove 8. When the upper die 7 resets, at this time, the guiding block 12 will enter the inclined guide groove 9 along the guide plate 15 and slide inside the inclined guide groove 9 to automatically push the conveying plate 2.

[0031] In this embodiment, pads are symmetrically arranged on both sides of the bottom of the base 1, and anti-slip pads are provided at the bottoms of the pads.

[0032] Local working principle: The use of the pads can support the device, and the use of the anti-slip pads improves the stability of the device.

[0033] In this embodiment, a sliding groove 17 is formed along the length direction on the top of the base 1. A slider 18 is slidably installed inside the sliding groove 17. The top of the slider 18 is fixedly connected to the bottom of the conveying plate 2.

[0034] Local working principle: When the conveying plate 2 slides, it will drive the slider 18 to slide inside the sliding groove 17 to ensure that the conveying plate 2 slides in a straight line.

[0035] In this embodiment, a second spring 19 is installed between the end of the slider 18 and the inner end of the sliding groove 17.

[0036] Local working principle: When the conveying plate 2 slides, it will squeeze the second spring 19. After the guiding block 12 is located inside the horizontal guide groove 10, the second spring 19 can automatically control the reset of the conveying plate 2.

[0037] In this embodiment, pull rods are fixed at both ends of the conveying plate 2, and the shape of the pull rods is U-shaped.

[0038] Local working principle: The use of the pull rods can control the sliding of the conveying plate 2 and ensure the stability of the initial position of the conveying plate 2.

[0039] As described above, it is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and concept of the present utility model, makes equivalent substitutions or changes, all of which belong to the protection scope of the present utility model.
