[0002] High-quality titanium automotive springs refer to automotive springs made primarily of high-performance titanium alloys. They are widely used in key components such as suspension systems and valve mechanisms, aiming to achieve lightweight, high durability, and excellent handling performance.

[0003] In the existing technology, when rolling ears on high-quality titanium springs, most workers place the high-quality titanium springs inside the forming box and then press down the first turn at the end of the high-quality titanium springs using a manual pressing device to complete the rolling ear forming of the high-quality titanium springs. However, the spring rolling ear forming device is all manually operated by workers, which not only has a low degree of automation, but also reduces the efficiency of spring rolling ear forming.

[0012] Furthermore, the surface of the material storage guide box is provided with a groove, the inner wall of the groove is slidably connected to the surface of the slider, the bottom of the baffle plate is in contact with the bottom of the inner wall of the material storage guide box, the bottom of the inner wall of the material storage guide box is provided with an isolation hole, the surface of the isolation plate is in contact with the inner wall of the isolation hole, the bottom of the center plate is in contact with the bottom of the inner wall of the material storage guide box, and the side of the material storage guide box near the end of the support frame is fixedly connected to the end of the support frame.

[0013] Furthermore, the molding mechanism includes a molding box, a telescopic rod fixedly connected to the inner wall of the molding box, a pull plate hinged to the surface of the slide plate, a connecting rod hinged to the end of the pull plate away from the slide plate, a pad fixedly connected to the bottom of the inner wall of the molding box, a guide rail fixedly connected to the end of the molding box, a moving plate slidably connected to the surface of the guide rail, a power device and a push plate fixedly connected to the top of the moving plate, a pressing block fixedly connected to the output end of the power device, a passive rod hinged to the bottom of the push plate, a telescopic plate hinged to the end of the passive rod away from the push plate, and a straightening plate fixedly connected to the end of the telescopic plate.

[0014] Furthermore, one end of the telescopic rod is close to the fixed ring and penetrates the surface of the molding box, and is fixedly connected to the surface of the fixed ring. The bottom of the fixed ring contacts the bottom of the inner wall of the molding box. Movable grooves are provided on both sides of the inner wall of the molding box. The two ends of the sliding plate are slidably connected to the inner wall of the movable groove. The end of the connecting rod away from the pull plate is fixedly connected to the surface of the curved plate. The end of the telescopic plate away from the straightening plate is fixedly connected to both sides of the support frame.

[0015] Furthermore, the collection mechanism includes a collection box, and two bidirectional telescopic cylinders are fixedly connected to the bottom sides of the forming box, with a push rod hinged to the output end of the bidirectional telescopic cylinder.

[0016] Furthermore, the top of the collection box is fixedly connected to the bottom of the molding box, the end of the lower push rod away from the bidirectional telescopic cylinder is hinged to the end of the driven block, and the surface of the sealing plate is hinged to the inner wall of the molding box.

[0017] The present invention has the following beneficial effects:

[0018] This invention employs a blocking mechanism. After the blocking plate moves upward into position, the first high-quality titanium spring smoothly falls into the inner wall of the molding box via the slope of the material storage guide box. When the electric telescopic rod pulls the push rod to reset the entire assembly, the blocking plate and the isolation plate return to their original positions. The isolation plate no longer contacts the second high-quality titanium spring, which then rolls down the slope towards the surface of the blocking plate. As the isolation plate moves upward, it drives the bent rod upward. When the bent rod moves, it pulls the end of the driven plate upward, while the other end of the driven plate pulls the centering plate towards each other. As the centering plate moves, it pushes the high-quality titanium spring towards the center. Effectively, through the cooperation of the blocking plate and the isolation plate, when the blocking plate is raised, the isolation plate blocks the second high-quality titanium spring, allowing the high-quality titanium springs to fall into the molding box one by one. Simultaneously, the movement of the centering plate centers the high-quality titanium springs inside the material storage guide box.

[0019] This invention, through the setting of a forming mechanism, involves the lower pressure block contacting and pressing the first coil at the end of a high-quality titanium spring during its movement, bending the first coil at the end of the high-quality titanium spring to a 90-degree angle, thereby completing the forming of the high-quality titanium spring end ear. As the moving plate slides downwards, it drives the lower push plate downwards. When the lower push plate moves, it pushes the end of the passive rod downwards, while the other end of the passive rod pushes the telescopic plate to extend in a direction closer to each other. When the telescopic plate extends, it pushes the straightening plate to move in a direction closer to each other. During the movement of the straightening plate, it contacts the high-quality titanium spring on the surface of the conveyor belt, thus positioning the high-quality titanium spring in the center of the conveyor belt surface. The fixing ring effectively secures the high-quality titanium spring, providing stability during the ear-forming process. Simultaneously, it automatically completes the ear-forming, replacing manual ear-forming of the high-quality titanium spring, improving efficiency, and achieving a high degree of automation. Furthermore, the straightening plate centers the high-quality titanium spring on the surface of the conveyor belt, preventing misalignment.

[0020] This invention utilizes a collection mechanism. After the high-quality titanium spring ear is formed, the fixing ring separates from the high-quality titanium spring. At this point, a bidirectional telescopic cylinder is activated, pulling the end of the lower push rod towards each other. The other end of the lower push rod pushes the driven block downward. When the driven block moves, it pulls the end of the expansion plate downward. At the same time, the other end of the expansion plate pulls the sealing plate downward. When the sealing plate moves, it expands downward and away from each other. When the sealing plate opens, the high-quality titanium spring falls into the collection box. The expansion plate effectively opens the sealing plate, allowing the completed high-quality titanium spring to automatically fall into the inner wall of the collection box, thus achieving automatic storage and saving labor.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1 - Figure 8 As shown, the present invention is a processing device for forming the end lugs of automotive coil springs, including a support frame 1, a conveyor belt 2 provided on the inner wall of the support frame 1, support rods 3 fixedly connected to both sides of the support frame 1, a spring forming device 4 fixedly connected to the end of the support rods 3 away from the support frame 1, a placement plate 5 fixedly connected to the surface of the support rods 3, and a guide plate 6 fixedly connected to the surface of the spring forming device 4. The invention is characterized by further comprising:

[0035] The blocking mechanism 10 includes a slider 16, a partition plate 17 fixedly connected to the surface of the slider 16, and a bent rod 18 fixedly connected to the bottom of the partition plate 17. After the blocking plate 15 moves upward into place, the first high-quality titanium spring will smoothly fall into the inner wall of the forming box 31 through the slope of the material storage guide box 11. When the electric telescopic rod 12 pulls the push rod 13 to reset the whole, the blocking plate 15 and the partition plate 17 are reset to their original positions, and the partition plate 17 no longer contacts the second high-quality titanium spring. The second high-quality titanium spring will roll down the slope to the surface of the blocking plate 15. While the partition plate 17 moves upward, it will drive the bent rod 18 to move upward.

[0036] The forming mechanism 30 includes a fixed ring 33, a push plate 34 is hinged to the surface of the fixed ring 33, and a slide plate 35 is hinged to the end of the push plate 34 away from the fixed ring 33.

[0037] The collection mechanism 50 includes a driven block 54, an expansion plate 55 is hinged to the surface of the driven block 54, and a sealing plate 56 is hinged to the end of the expansion plate 55 away from the driven block 54.

[0038] The end of the guide plate 6 away from the spring forming device 4 is in contact with the surface of the conveyor belt 2, and the surface of the placement plate 5 is provided with a placement groove, and the end of the placement plate 5 is in contact with the surface of the spring forming device 4.

[0039] The blocking mechanism 10 includes a material storage guide box 11. An electric telescopic rod 12 is fixedly connected to the surface of the material storage guide box 11. A push rod 13 is hinged to the output end of the electric telescopic rod 12. A curved plate 14 is hinged to the end of the push rod 13 away from the electric telescopic rod 12. A blocking plate 15 is fixedly connected to the end of the curved plate 14 away from the push rod 13. A driven plate 19 is hinged to the end of the bent rod 18. When the bent rod 18 moves, it pulls the end of the driven plate 19 upward, and the other end of the driven plate 19 pulls the centering plate 20 closer to each other. The centering plate 20 moves in the direction of the movement, pushing the high-quality titanium springs towards the center. This is effectively achieved through the cooperation of the blocking plate 15 and the isolation plate 17. When the blocking plate 15 is lifted upward, the isolation plate 17 blocks the second high-quality titanium springs, allowing the high-quality titanium springs to fall into the molding box 31 one by one. At the same time, the centering plate 20 also centers the high-quality titanium springs inside the storage guide box 11 during its movement. The centering plate 20 is hinged to the end of the driven plate 19 away from the bent rod 18.

[0040] The surface of the storage guide box 11 is provided with a groove, the inner wall of the groove is slidably connected to the surface of the slider 16, the bottom of the baffle plate 15 is in contact with the bottom of the inner wall of the storage guide box 11, the bottom of the inner wall of the storage guide box 11 is provided with an isolation hole, the surface of the isolation plate 17 is in contact with the inner wall of the isolation hole, the bottom of the center plate 20 is in contact with the bottom of the inner wall of the storage guide box 11, and the storage guide box 11 is fixedly connected to the end of the support frame 1 on the side near the end of the support frame 1.

[0041] The molding mechanism 30 includes a molding box 31. A telescopic rod 32 is fixedly connected to the inner wall of the molding box 31. A pull plate 36 is hinged to the surface of the slide plate 35. A connecting rod 37 is hinged to the end of the pull plate 36 away from the slide plate 35. A pad 38 is fixedly connected to the bottom of the inner wall of the molding box 31. A guide rail 39 is fixedly connected to the end of the molding box 31. A moving plate 40 is slidably connected to the surface of the guide rail 39. A power device 41 and a push plate 43 are fixedly connected to the top of the moving plate 40. A pressing block 42 is fixedly connected to the output end of the power device 41. A passive rod 44 is hinged to the bottom of the push plate 43. The end of the rod 44 away from the push plate 43 is hinged to a telescopic plate 45. During the movement of the pressure block 42, it will contact and squeeze the first coil of the high-quality titanium spring end, bending the first coil of the high-quality titanium spring end to ninety degrees, thereby completing the ear forming of the high-quality titanium spring end. While the moving plate 40 slides down, it will drive the push plate 43 to move down. When the push plate 43 moves, it will push the end of the passive rod 44 to move down, and the other end of the passive rod 44 will push the telescopic plate 45 to extend in the direction of mutual approach. The end of the telescopic plate 45 is fixedly connected to a straightening plate 46.

[0042] The telescopic rod 32 extends near one end of the fixed ring 33 and passes through the surface of the molding box 31, and is fixedly connected to the surface of the fixed ring 33. The bottom of the fixed ring 33 contacts the bottom of the inner wall of the molding box 31. Movable grooves are provided on both sides of the inner wall of the molding box 31. The two ends of the sliding plate 35 are slidably connected to the inner wall of the movable groove. The end of the connecting rod 37 away from the pull plate 36 is fixedly connected to the surface of the curved plate 14. The end of the telescopic plate 45 away from the straightening plate 46 is fixedly connected to both sides of the support frame 1. When the telescopic plate 45 extends, it pushes the straightening plate 46 to move in a direction closer to each other, thus correcting the straightening plate 46. During the movement of plate 46, it will come into contact with the high-quality titanium spring on the surface of conveyor belt 2, thereby positioning the high-quality titanium spring in the center of the surface of conveyor belt 2. The high-quality titanium spring can be effectively fixed by fixing ring 33, which plays a stabilizing role during the ear-rolling process of the high-quality titanium spring end. At the same time, it can automatically complete the ear-rolling, replacing manual ear-rolling of high-quality titanium spring, improving the efficiency of ear-rolling, and having a high degree of automation. In addition, the straightening plate 46 can center the high-quality titanium spring on the surface of conveyor belt 2, thereby preventing the phenomenon of displacement.

[0043] The collection mechanism 50 includes a collection box 51. Two bidirectional telescopic cylinders 52 are fixedly connected to both sides of the bottom of the molding box 31. A lower push rod 53 is hinged to the output end of the bidirectional telescopic cylinder 52. After the high-quality titanium spring coil is formed, the fixing ring 33 will separate from the high-quality titanium spring. At this time, the bidirectional telescopic cylinder 52 is activated to pull the end of the lower push rod 53 to move towards each other, while the other end of the lower push rod 53 will push the driven block 54 to move downward.

[0044] The top of the collection box 51 is fixedly connected to the bottom of the molding box 31. The end of the push rod 53 away from the bidirectional telescopic cylinder 52 is hinged to the end of the driven block 54. The surface of the sealing plate 56 is hinged to the inner wall of the molding box 31. When the driven block 54 moves, it will pull the end of the expansion plate 55 downward. At this time, the other end of the expansion plate 55 will pull the sealing plate 56 downward. When the sealing plate 56 moves, it will expand downward and in a direction away from each other. When the sealing plate 56 is opened, the high-quality titanium spring will fall into the interior of the collection box 51. The sealing plate 56 can be opened effectively by the expansion plate 55, so that the high-quality titanium spring with rolled ears will automatically fall into the inner wall of the collection box 51 and complete the automatic storage function, saving labor.

[0045] In use, first, high-quality titanium material is placed on the inner wall of the placement groove. Then, the spring forming device 4 is activated to process the high-quality titanium material into a high-quality titanium spring. The formed high-quality titanium spring will fall into the inner wall of the guide plate 6 and then flow into the surface of the conveyor belt 2 along the slope of the guide plate 6. At this time, the conveyor belt 2 is activated to transport the high-quality titanium spring to the inner wall of the storage guide box 11. Since the two ends of the high-quality titanium spring are aligned with the two ends of the conveyor belt 2, after falling into the inner wall of the storage guide box 11, it remains in a horizontal state and rolls towards the surface of the baffle plate 15, where it is blocked. At this time, the electric telescopic rod 12 is activated to push the end of the push rod 13 towards the end of the storage guide box 11, while the other end of the push rod 13 pushes the curved plate 14 towards... As the curved plate 14 moves, it causes the slider 16 to slide upwards along the inner wall of the groove, simultaneously moving the blocking plate 15 upwards. The sliding slider 16 also causes the isolation plate 17 to move upwards. During the movement of the isolation plate 17, the first high-quality titanium spring is separated from the second high-quality titanium spring, thus blocking the second high-quality titanium spring. After the blocking plate 15 moves into position, the first high-quality titanium spring smoothly falls into the inner wall of the forming box 31 via the slope of the material storage guide box 11. When the electric telescopic rod 12 pulls the push rod 13 to reset the entire assembly, the blocking plate 15 and the isolation plate 17 return to their original positions. The isolation plate 17 no longer contacts the second high-quality titanium spring, and the second high-quality titanium spring will then slide down the slope... As the plate rolls towards the surface of the baffle plate 15, the upward movement of the isolation plate 17 causes the bent rod 18 to move upward. When the bent rod 18 moves, it pulls the end of the driven plate 19 upward, while the other end of the driven plate 19 pulls the centering plate 20 towards a closer direction. As the centering plate 20 moves, it pushes the high-quality titanium spring towards the center. When the curved plate 14 moves upward, it causes the connecting rod 37 to move upward. When the connecting rod 37 moves, it pulls the end of the pull plate 36 upward. At this time, the other end of the pull plate 36 pulls the slide plate 35 along the inner wall of the moving groove towards the connecting rod 37. When the slide plate 35 slides, it pulls the end of the push plate 34 towards the connecting rod 37, while the other end of the push plate 34 pulls the fixing ring 33 towards a more distant direction. When the fixed ring 33 moves, it pushes the telescopic rod 32 to retract in a direction away from each other. At this time, the high-quality titanium spring will fall into the interior of the molding box 31. When the curved plate 14 resets, it will drive the connecting rod 37 to move downward. When the connecting rod 37 moves, it will push the slide plate 35 to slide towards the pad 38 on the inner wall of the moving groove, and push the high-quality titanium spring towards the pad 38, so that the high-quality titanium spring contacts the pad 38. When the slide plate 35 slides, it will push the end of the push plate 34 towards the pad 38, and the other end of the push plate 34 will push the fixed ring 33 to move in a direction away from each other, thereby fixing the high-quality titanium spring. When the fixed ring 33 moves, it will pull the telescopic rod 32 to extend in a direction closer to each other.After the fixing ring 33 fixes the high-quality titanium spring, the power device 41 is activated to make the moving plate 40 slide downward on the surface of the guide rail 39. At the same time, it will also drive the lower pressure block 42 to move downward. During the movement of the lower pressure block 42, it will contact and squeeze the first coil at the end of the high-quality titanium spring, bending the first coil at the end of the high-quality titanium spring to a ninety-degree angle, thereby completing the ear forming of the end of the high-quality titanium spring. As the moving plate 40 slides downward, it will drive the lower push plate 43 to move downward. When the lower push plate 43 moves, it will push the end of the passive rod 44 to move downward. The other end of the passive rod 44 will push the telescopic plate 45 to extend in a direction closer to each other. When the telescopic plate 45 extends, it will push the straightening plate 46 to move in a direction closer to each other. During its movement, the spring 6 will come into contact with the high-quality titanium spring on the surface of the conveyor belt 2, thus positioning the high-quality titanium spring in the center of the surface of the conveyor belt 2. After the high-quality titanium spring's coiled ear is formed, the fixing ring 33 will separate from the high-quality titanium spring. At this time, the bidirectional telescopic cylinder 52 is activated, pulling the end of the lower push rod 53 towards each other. The other end of the lower push rod 53 will push the driven block 54 downward. When the driven block 54 moves, it will pull the end of the expansion plate 55 downward. At this time, the other end of the expansion plate 55 will pull the sealing plate 56 downward. When the sealing plate 56 moves, it will expand downward and in a direction away from each other. After the sealing plate 56 opens, the high-quality titanium spring will fall into the collection box 51.
