Abstract
Description
Technical Field
[0001] This invention belongs to the field of stamping equipment technology, and relates to a continuous stamping forming equipment for automotive sunroof guide rails. Background Technology
[0002] In the automotive manufacturing industry, the processing and manufacturing of sunroof rails is a crucial technical step. Traditional sunroof manufacturing methods primarily involve multiple steps such as cutting, bending, stamping, and welding. These steps typically require various equipment and processes, and a significant amount of manual labor. However, with technological advancements, stamping has gradually been applied to sunroof manufacturing. Stamping is a metal processing method that uses the pressure of molds and stamping equipment to deform metal sheets into the desired shape. This processing method can efficiently manufacture sunroofs with high precision and consistent quality.
[0003] Compared to traditional processing methods, stamping has significant advantages in manufacturing automotive sunroofs. Firstly, stamping can drastically reduce processing steps, increasing production efficiency. Secondly, it reduces reliance on manual labor, lowering manufacturing errors and costs. Finally, stamping better ensures the quality and stability of the sunroof, enhancing product competitiveness. However, the multiple grooves and other features of sunroof rails make the stamping process relatively complex. It typically requires multiple stamping operations using multiple stamping machines. During the stamping process, the semi-finished sunroof rails need to be transferred multiple times, usually using robotic arms or other automated equipment. This results in a large number of equipment required for sunroof rail manufacturing, leading to high manufacturing costs. Summary of the Invention
[0004] The purpose of this invention is to provide a continuous stamping forming equipment for automotive sunroof guide rails, which can perform multiple stampings of automotive sunroof guide rails, enabling one machine to complete the production and reduce manufacturing costs.
[0005] To solve the above technical problems, the present invention provides a continuous stamping forming equipment for automotive sunroof guide rails, including a machine base. The machine base has a rotating disk rotatably connected to its upper end, and a drive motor for driving the rotating disk is installed inside the machine base. The upper end of the rotating disk is provided with multiple circumferentially distributed stamping grooves. An upwardly arranged mounting column is provided inside the rotating disk on the machine base. A mounting frame is horizontally arranged at the upper end of the mounting column. A downwardly arranged hydraulic cylinder is mounted on the mounting frame. A mounting plate is provided at the lower end of the hydraulic cylinder. A horizontally arranged stamping shaft is rotatably connected to the mounting plate. A rotary motor for driving the stamping shaft is installed on the mounting plate. Multiple circumferentially distributed stamping strips, each corresponding to one of the stamping grooves, are horizontally arranged on the outer circumference of the stamping shaft. Each stamping groove contains a different forming groove. Each free end of a stamping strip is provided with a forming pressure strip corresponding to its corresponding forming groove.
[0006] The machine base is equipped with two linear motors arranged horizontally outward at both ends of the side below the stamping shaft. The two linear motors are located on both sides of the stamping shaft. Each linear motor has a limit cylinder at the upper end of its mover. Each limit cylinder has a limit groove with a non-circular cross section. Each limit cylinder has a hollow rotating cylinder at the upper end. Each rotating cylinder has an adjustment motor installed at the upper end. The power output shaft of each adjustment motor is connected to a threaded shaft that extends downward into the bottom of the limit groove and is rotatably connected thereto. Each limit groove is slidably connected to a threaded sleeve that is threadedly connected to the corresponding threaded shaft. Each threaded sleeve has a rotating ring rotatably connected to the corresponding rotating cylinder at the upper end.
[0007] Each rotating cylinder has a guide groove on its side wall that communicates with its interior. Each guide groove includes a spiral groove that is spirally arranged and a vertical groove that communicates with the lower end of the spiral groove and is arranged downwards. The two vertical grooves are arranged opposite each other and both face the middle of the stamping shaft. Each rotating cylinder is rotatably connected to a collar. Each rotating collar is connected to the collar through a sliding shaft that is slidably connected to the corresponding guide groove. Each collar has an installation strip that extends outwards. Each installation strip has multiple suction cups installed at its lower end. Each suction cup is connected to an air pipe that extends upwards through the corresponding installation strip. The air pipe is used to connect to a vacuum generator. When the sliding shaft slides to the bottom of the corresponding vertical groove, the corresponding suction cup extends into the bottom of the corresponding stamping groove.
[0008] According to the above technical solution, when stamping the sunroof guide rail, the aluminum alloy plate is first cut into strips that are the same as the stamping groove. The strips are placed into the first stamping groove. Then the stamping groove is rotated to the bottom of the stamping shaft. The hydraulic cylinder extends and drives the stamping shaft to descend, so that the downward stamping strip extends into the stamping groove. The forming groove in the stamping groove cooperates with the forming strip on the stamping strip to stamp the strip into a preliminary shape. After completion, the hydraulic cylinder shortens and drives the stamping shaft to rise.
[0009] Then, adjust the motor rotation to drive the threaded shaft to rotate. The rotating threaded shaft drives the threaded sleeve to move downward. The threaded sleeve moves downward and drives the rotating ring to move downward. During the downward movement of the rotating ring, the sliding shaft slides relative to the guide groove, which eventually drives the mounting strip to rotate inward first and then move downward, so that the suction cup extends into the stamping groove. The vacuum generator makes the suction cup generate negative pressure to suck up the sunroof guide rail. Then, adjust the motor to reverse and make the suction cup suck up the sunroof guide rail and rise.
[0010] The rotating disc rotates, causing the lower stamping groove to rotate below the stamping shaft. The motor is then adjusted to rotate forward again, causing the suction cup to place the sunroof guide rail into the stamping groove. After the vacuum generator controls the suction cup to lose negative pressure, the motor is adjusted to rotate in reverse, driving the mounting strip to rotate upward and outward back to its original position. The rotating motor drives the stamping shaft to rotate, causing the stamping strip on the stamping shaft that mates with the lower stamping groove to rotate downward. Subsequently, the hydraulic cylinder extends, pushing the stamping strip into the stamping groove for secondary stamping.
[0011] After multiple stamping processes to achieve the final shape of the sunroof guide rail, the motor drives the suction cup into the stamping groove to lift the sunroof guide rail. The linear motor then operates to move the suction cup to the outside of the machine base, whereupon the suction cup cuts off the negative pressure, allowing the sunroof guide rail to be lowered, thus completing one stamping cycle of the sunroof guide rail.
[0012] The invention is further configured such that a first mounting platform is provided on one side of the base below the stamping shaft, and the free end of each linear motor extends outward from the outer edge of the first mounting platform. The base is connected to a second mounting platform located above the rotating disk. The upper ends of the first and second mounting platforms are provided with slide rails. The two slide rails are arranged opposite each other and are respectively located on both sides of the stamping shaft. Each slide rail is slidably connected with a slide bar. The first and second mounting platforms are each equipped with a push motor for driving the corresponding slide bar to slide. Each slide bar has a pressing and bending strip on its free edge. Each stamping groove has bending slots communicating with its interior on both its inner and outer sides.
[0013] With the above technical solution, when bending is required during the process, the motor is driven to move the slide bar towards the stamping groove, so that the extrusion bending strip at the front end of the slide bar rises from the bending slot into the stamping groove to extrude and bend the sunroof guide rail.
[0014] The invention is further configured such that each slide bar has a mounting head at both ends of its free edge, and a horizontal replacement shaft is rotatably connected between the two mounting heads on each slide bar. Multiple extrusion bending bars are arranged circumferentially around the outer periphery of the horizontal replacement shaft. Each horizontal replacement shaft has a sliding hole at both ends. A telescopic motor is installed outside each mounting head. The telescopic shaft of each telescopic motor is connected to a telescopic slide shaft that is slidably connected to the corresponding sliding hole. A spiral groove is provided on the inner wall of each sliding hole. A limiting protrusion that is slidably connected to the corresponding spiral groove is provided on the outer wall of the free end of each telescopic slide shaft.
[0015] With the above technical solution, when it is necessary to replace the extrusion bending strip during the process, the telescopic motor drives the telescopic sliding shaft to extend and retract within the sliding hole. The limit protrusion drives the horizontal replacement shaft to rotate, so that the corresponding extrusion bending strip faces the stamping groove, and then drives the extrusion bending strip to extend into the stamping groove to extrude and bend the sunroof guide rail.
[0016] The present invention is further configured such that the power output shaft of each push motor is connected to a threaded drive shaft parallel to the corresponding slide bar, and a plurality of threaded slide sleeves are threadedly connected to each threaded drive shaft, and a push bar is rotatably connected between each threaded slide sleeve and the corresponding slide bar.
[0017] The present invention is further configured such that both sides of the free end of the mounting frame are provided with support columns that are connected to both ends of the first mounting platform.
[0018] The present invention is further configured such that the inner wall of the rotating disk is provided with an internal gear, and the power output shaft of the drive motor is connected to a drive gear that meshes with the internal gear.
[0019] The present invention is further configured such that the stamping shaft extends out of the mounting plate and is connected to a worm gear, and the power output shaft of the rotating motor is connected to a worm that meshes with the worm gear.
[0020] The present invention is further configured such that a material leakage groove is provided below the stamping shaft and extending downward through the machine base.
[0021] The present invention is further configured such that the helical angle of each helical groove is 90°.
[0022] Compared with existing technologies, it has the following beneficial effects:
[0023] Firstly, this invention uses multiple rotatable stamping grooves and multiple rotatable stamping strips to cooperate, so that one stamping machine can complete multiple stampings of the sunroof guide rail. It does not require multiple stamping machines to work together or multiple machines to transfer the sunroof guide rail, which can significantly reduce the manufacturing cost of the sunroof guide rail.
[0024] Secondly, during the stamping of the sunroof guide rail, the invention utilizes a clever drive structure, where a single adjustment motor can drive the suction cup to turn and downwards to hold the sunroof guide rail, facilitating the replacement of the stamping groove. Furthermore, it can avoid the stamping shaft during stamping, preventing the suction cup from obstructing the downward movement of the stamping shaft.
[0025] Thirdly, the present invention also has extrusion and bending mechanisms on both sides. Since many sunroof guide rails have complex shapes, they may not be able to be processed by stamping alone. Therefore, extrusion and bending mechanisms are added on both sides to enable the equipment to manufacture more complex sunroof guide rails. Attached Figure Description

The upper end of the mounting column 7 is provided with a horizontally mounted mounting bracket 8. The mounting bracket 8 is equipped with two opposing and downwardly positioned hydraulic cylinders 9. The lower end of each hydraulic cylinder 9 is provided with a mounting plate 10. The two mounting plates 10 are rotatably connected to a horizontally positioned stamping shaft 11. A rotary motor 12 for driving the stamping shaft 11 to rotate is mounted on the mounting plate 10. The stamping shaft 11 passes through the mounting plate 10 and is connected to a worm gear 13. The power output shaft of the rotary motor 12 is connected to a worm 14 that meshes with the worm gear 13. Four stamping bars 15 are horizontally arranged on the outer periphery of the stamping shaft 11, each corresponding to a stamping groove 6. Each stamping groove 6 has a different forming groove 16. The free end of each stamping bar 15 has a forming pressure bar 17 corresponding to the corresponding forming groove 16. Each stamping bar 15 cooperates with the corresponding stamping groove 6 to complete one stamping. A punching shaft is provided on the stamping bar 15, and corresponding punches are provided in the stamping groove 6 for punching and drilling holes on the sunroof guide rail. A material drain groove 18 is provided below the stamping shaft 11, penetrating downward through the machine base 1, to facilitate the discharge of waste material during stamping and drilling.
[0036] A linear motor 19 is horizontally arranged on both the left and right ends of the base 1 below the stamping shaft 11. The two linear motors 19 are located on both sides of the stamping shaft 11. Each linear motor 19 has a limiting cylinder 20 at the upper end of its mover. Each limiting cylinder 20 has a limiting groove 21 with a non-circular cross section. In this embodiment, the limiting groove 21 has a square cross section. Each limiting cylinder 20 has a hollow rotating cylinder 22 at the upper end. Each rotating cylinder 22 has an adjusting motor 23 installed at the upper end. The power output shaft of each adjusting motor 23 is connected to a threaded shaft 24 that extends downward into the bottom of the limiting groove 21 and is rotatably connected to it.

Each rotating cylinder 22 is rotatably connected to a collar 28. Each rotating collar 28 is connected to the corresponding guide groove via a shaft. The sliding shaft 29 is connected to the collar 28. Each collar 28 has an outwardly mounted strip 30. Each mounting strip 30 has two suction cups 31 mounted at its lower end. Each suction cup 31 is connected to an air pipe 32 that extends upward through the corresponding mounting strip 30. The air pipe 32 is used to connect to the vacuum generator. When the sliding shaft 29 slides to the bottom of the corresponding vertical groove 272, the corresponding suction cup 31 extends into the bottom of the corresponding stamping groove 6 to pick up the sunroof guide rail located in the stamping groove 6.
[0038] A first mounting platform 33 is provided on one side of the base 1 below the stamping shaft 11. A support column 34 connected to both ends of the first mounting platform 33 is provided on both sides of the free end of the mounting bracket 8. The free end of each linear motor 19 extends out of the first mounting platform 33, so that the suction cup 31 can suck up the sunroof guide rail and extend it out of the first mounting platform 33 for taking out the stamped sunroof guide rail. The base 1 is connected to a second mounting platform 35 located above the rotating disk 2. The upper end of both the first mounting platform 33 and the second mounting platform 35 is provided with a slide rail 36. The two slide rails 36 are arranged opposite each other and are located on both sides of the stamping shaft 11. Each slide rail 36 is slidably connected to a slide bar 37. Each of the first mounting platform 33 and the second mounting platform 35 is equipped with a push motor 38 for driving the corresponding slide bar 37 to slide. The power output shaft of each push motor 38 is connected to a threaded drive shaft 39 parallel to the corresponding slide bar 37. Each threaded drive shaft 39 is threadedly connected to two threaded sleeves 40. Each threaded sleeve 40 and the corresponding slide bar 37 are rotatably connected to a push bar 41. The push motor 38 drives the threaded drive shaft 39 to rotate, which drives the threaded sleeves 40 to move, so that the push bar 41 pushes the slide bar 37 to move relative to the slide rail 36.
[0039] Each slide bar 37 has a mounting head 42 at both ends of its free edge. A horizontal replacement shaft 43 is rotatably connected between the two mounting heads 42 on each slide bar 37. Each horizontal replacement shaft 43 has two different extrusion bending strips 44 on its outer periphery. Each stamping groove 6 has a bending slot 45 on both its inner and outer sides that communicates with its interior, so that the extrusion bending strips 44 can be inserted into the stamping groove 6 to extrude and bend the pop-up window guide rail. Each horizontal changing shaft 43 has a sliding hole 46 at both ends. Each mounting head 42 is equipped with a telescopic motor 47. The telescopic shaft of each telescopic motor 47 is connected to a telescopic sliding shaft 48 that is slidably connected to the corresponding sliding hole 46. The inner wall of each sliding hole 46 is provided with a spiral groove 49 with a spiral angle of 360 degrees. The outer wall of the free end of each telescopic sliding shaft 48 is provided with a limiting protrusion 50 that is slidably connected to the corresponding spiral groove 49. The telescopic motor 47 drives the telescopic sliding shaft 48 to extend and retract within the sliding hole 46. Through the connection between the limiting protrusion 50 and the spiral groove 49, the horizontal changing shaft 43 is driven to rotate, thereby automatically changing the required extruded bending strip 44.
[0040] Working principle: When stamping the sunroof guide rail, the aluminum alloy plate is first cut into strips that are the same as the stamping groove 6. The strips are placed into the first stamping groove 6. Then the stamping groove 6 is rotated to the bottom of the stamping shaft 11. The hydraulic cylinder 9 extends and drives the stamping shaft 11 to descend, so that the downward stamping strip 15 extends into the stamping groove 6. The forming groove 16 in the stamping groove 6 cooperates with the forming pressure strip 17 on the stamping strip 15 to stamp the strip into a preliminary shape. After completion, the hydraulic cylinder 9 shortens and drives the stamping shaft 11 to rise.
[0041] Then, the motor 23 is adjusted to rotate, which drives the threaded shaft 24 to rotate. The rotating threaded shaft 24 drives the threaded sleeve 25 to move downward. The threaded sleeve 25 moves downward and drives the rotating ring 26 to move downward. During the downward movement of the rotating ring 26, the sliding shaft 29 slides relative to the guide groove 27, which finally drives the mounting strip 30 to rotate inward first and then move downward, so that the suction cup 31 extends into the stamping groove 6. The vacuum generator makes the suction cup 31 generate negative pressure to suck up the sunroof guide rail. Then, the motor 23 is adjusted to reverse, so that the suction cup 31 sucks up the sunroof guide rail and rises.
[0042] Rotating disc 2 rotates, causing the lower stamping groove 6 to rotate below the stamping shaft 11. Adjusting motor 23 rotates forward again, causing suction cup 31 to place the sunroof guide rail into the stamping groove 6. After the vacuum generator controls suction cup 31 to lose negative pressure, adjusting motor 23 reverses, driving the mounting strip 30 to rotate upward and outward to its original position. Rotating motor 12 drives stamping shaft 11 to rotate, causing the stamping strip 15 on stamping shaft 11 that cooperates with the lower stamping groove 6 to rotate downward. Then, hydraulic cylinder 9 extends, pushing the stamping strip 15 into the stamping groove 6 for secondary stamping.
[0043] When bending is required during the process, the motor 38 drives the slide bar 37 to move towards the stamping groove 6, so that the extrusion bending bar 44 at the front end of the slide bar 37 rises from the bending slot 45 into the stamping groove 6 to extrude and bend the sunroof guide rail. When the extrusion bending bar 44 needs to be replaced during the process, the telescopic motor 47 drives the telescopic slide shaft 48 to extend and retract within the slide hole 46, and drives the horizontal replacement shaft 43 to rotate through the limiting protrusion 50, so that the corresponding extrusion bending bar 44 faces the stamping groove 6, and then drives the extrusion bending bar 44 to extend into the stamping groove 6 to extrude and bend the sunroof guide rail.
[0044] After multiple stampings to achieve the final shape of the sunroof guide rail, the motor 23 drives the suction cup 31 into the stamping groove 6 to lift the sunroof guide rail. The linear motor 19 then operates to move the suction cup 31 to the outside of the first mounting platform 33, whereby the suction cup 31 cuts off the negative pressure, allowing the sunroof guide rail to be lowered, thus completing one stamping cycle of the sunroof guide rail.
[0045] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
