Description
Technical Field
[0001] This utility model relates to the field of roll forming profile stamping technology, and in particular to large-size roll forming profile stamping equipment. Background Technology
[0002] A car crash beam is a safety protection device located at the front and rear ends of a car. Its purpose is to effectively absorb and disperse the energy generated by a collision, reducing injury to occupants and evenly distributing impact force to other parts of the car body under different impact conditions, thus preventing concentrated force from causing excessive damage to one area. Crash beams are typically made of high-strength materials formed by roll forming. During the forming process, stress concentration can easily occur in the profile structure, affecting the overall performance of the crash beam. Stress relief methods include heat treatment, mechanical methods, energy field processing, natural stacking, and (electro)chemical processing. Mechanical methods, by applying low-frequency mechanical vibration, can promote dislocation slippage and stress homogenization within the material, making them suitable for large and complex structures, easy to operate, and without thermal effects.
[0003] Most existing large-size roll forming profile stamping equipment is equipped with continuous roll forming and stamping structures. During use, the formed profiles are stacked and stored. However, roll forming and stamping often cause stress concentration in the profile structure. Stacking after stamping has a weak effect on stress release, which can easily lead to a decrease in the quality of the profiles and a decrease in the performance of large-size roll forming profile stamping equipment.
[0004] Therefore, in view of the problem that when the existing large-size roll forming profile stamping equipment is used, the stacking and storage of the formed profiles has a weak effect on stress release, which easily leads to a decrease in the quality of the profiles and a decrease in the performance of the large-size roll forming profile stamping equipment, a large-size roll forming profile stamping equipment with a stress release structure can be designed.

The first placement frame 26 and the second placement frame 29 receive and position the roll-formed large-size profiles. The vibrating frame body 21 drives the large-size profiles to vibrate, thereby homogenizing the internal stress of the material through low-frequency vibration. The damper body 24, the first spring 25, the telescopic rod body 27, and the second spring 28 are used to protect the profiles.
[0019] Please see Figures 2-3 In this embodiment, a limiting groove 2 is provided at the lower end of the support body 1. A hydraulic push rod 3 is installed on the outer side of the limiting groove 2. A movable frame 4 is fixedly connected to the output end of the hydraulic push rod 3. A connecting plate 5 is fixedly connected to the outer side of the movable frame 4. The hydraulic push rod 3 is used to drive the movable frame 4 and the connecting plate 5 to move. The movable frame 4 is slidably connected to the limiting groove 2. The moving frame 4 and the connecting plate 5 are moved by the hydraulic push rod 3. A limiting rod 6 is installed on the inner side of the support body 1. A first motor 7 is installed at the upper end of the support body 1. A threaded rod 8 is fixedly connected to the output end of the first motor 7. The first motor 7 is used to drive the threaded rod 8 to rotate. A roller press body 9 is provided on the outer side of the limiting rod 6 and the threaded rod 8. A roller pressing roller body 10 is provided on the inner side of the roller press body 9. The profile is rolled and formed by the roller press body 9 and the roller pressing roller body 10.
[0020] Please see Figures 2-5In this embodiment, a mounting frame 11 is fixedly connected to the outer side of the roller press body 9. The mounting frame 11 is slidably connected to the limiting rod 6. A connecting frame 12 is fixedly connected to the outer side of the mounting frame 11. The connecting frame 12 is threadedly connected to the threaded rod 8. The roller press body 9 is moved by the threaded rod 8 and the limiting rod 6 in conjunction with the connecting frame 12 and the mounting frame 11. A support wheel 14 is rotatably connected to the outer side of the moving platform 13. A docking frame 15 is fixedly connected to the lower end of the moving platform 13. A mounting bolt 16 is rotatably connected to the outer side of the docking frame 15. The docking frame 15 is slidably connected to the connecting plate 5. The connecting plate 5 is threadedly connected to the mounting bolt 16. The moving platform 13 is moved by the support wheel 14, and the docking frame 15 docks with the connecting plate. 5. The moving platform 13 is fixed with bolts 16. A rotating platform 17 is fixed to one side of the moving platform 13. A dual-axis motor 18 is installed on the other side of the moving platform 13. A rotating disk 19 is fixedly connected to the output end of the dual-axis motor 18. The dual-axis motor 18 is used to drive the rotating disk 19 to rotate. A connecting rod 20 is rotatably connected to the outside of the rotating disk 19. The rotating disk 19 is rotatably connected to the limiting frame 23. A rotating seat 22 is installed on the rotating platform 17, so that the main body of the vibration frame 21 can rotate up and down around the rotating platform 17. The dual-axis motor 18 drives the rotating disk 19 and the connecting rod 20 to rotate, thereby driving the limiting frame 23 to move up and down, so that the main body of the vibration frame 21 vibrates as a whole.
[0021] During the roll forming process, firstly, the threaded rod 8 is driven to rotate by the first motor 7. Then, the main body 9 of the roll forming machine is moved by the threaded rod 8 and the limiting rod 6 in conjunction with the connecting frame 12 and the mounting frame 11. Next, the profile is roll-formed by the main body 9 of the roll forming machine and the roll forming roller body 10. Finally, the large-sized profile after roll forming is received, positioned, and fixed by the first placement frame 26 and the second placement frame 29. In use, firstly, the moving platform 13 is moved by the support wheel 14, thereby moving the vibration frame body 21 to facilitate docking with the support body 1. The moving frame 4 and connecting plate 5 are moved by the hydraulic push rod 3. Next, the connecting plate 5 is docked by the docking frame 15 and fixed by the mounting bolts 16. Then, the rotating seat 22 is installed by the rotating platform 17, which facilitates the vibration frame body 21 to rotate up and down around the rotating platform 17. The rotating disk 19 and connecting rod 20 are rotated by the dual-axis motor 18, thereby driving the limit frame 23 to move up and down, thus causing the vibration frame body 21 to vibrate as a whole. Finally, the vibration frame body 21, together with the first placement frame 26 and the second placement frame 29, drives the large-size profile to vibrate, thereby homogenizing the internal stress of the material through low-frequency vibration. The damper body 24, the first spring 25, the telescopic rod body 27 and the second spring 28 are used to protect the profile.
[0022] Through the above steps, by setting up the first placement frame 26 and the second placement frame 29 to receive and position the large-sized profile after roll forming, the large-sized profile is driven to vibrate by the vibration frame body 21 after roll forming. This low-frequency vibration homogenizes the internal stress of the material. During the vibration process, the damper body 24, the first spring 25, the telescopic rod body 27, and the second spring 28 reduce the possibility of the profile colliding with the vibration frame body 21 during vibration, thereby protecting the integrity of the overall structure of the profile. This reduces the internal stress while ensuring the integrity of the surface stress of the profile. This solves the problem that when existing large-sized roll forming profile stamping equipment is used, the stacking of the formed profiles after stamping has a weak effect on stress release, which easily leads to a decline in the quality of the profile and a decrease in the performance of the large-sized roll forming profile stamping equipment.
