Description

Technical Field

[0001] This application relates to the technical field of metal material bending and forming, and in particular to a sunroof slider bending and forming device. Background Technology

[0002] The sunroof guide rail and slider are key components of the automotive sunroof system, mainly serving to support, guide, and slide. Their structural precision and mechanical properties directly affect the smoothness of the sunroof's opening, its sealing performance, and its service life.

[0003] The forming of sunroof guide rails and sliders mainly relies on the bending process, that is, applying external force to the metal sheet through a mold to cause plastic deformation, thereby obtaining the required bending angle and shape. In the structural design of the sunroof slider, one end is equipped with an iron hook. In order to adapt to the specific assembly requirements or functional realization of the sunroof system, the iron hook is used to cooperate with the slot, limiting part or linkage mechanism in the sunroof track. The material of the sunroof slider is mostly high-strength alloy sheet. During the bending process, uneven mold pressure distribution or inaccurate positioning may occur.

[0004] Regarding the aforementioned technologies, the inventors believe that there are defects such as wrinkles and cracks caused by excessive force applied at one time. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this application provides a sunroof slider bending and forming device.

[0006] This application provides a sunroof slider bending and forming device, which adopts the following technical solution:

[0007] A sunroof slider bending and forming device includes a base plate, two sets of upright plates are arranged on both sides of the base plate, the upright plates are fixedly connected to the base plate, a stamping mechanism is arranged on the top of the two sets of upright plates, and a forming mechanism is arranged on the base plate between the two sets of upright plates. The forming mechanism includes a rotating traction device and a workpiece mold device. The workpiece mold device is detachably connected to the base plate, and the rotating traction device is rotatably connected to the workpiece mold device. A driving device is arranged on the base plate on one side of the upright plates, and the driving device provides power for the rotation of the rotating traction device.

[0008] By adopting the above technical solution, the two side uprights are fixedly connected to the bottom plate, and the top stamping mechanism forms a stable frame structure with the uprights. The mechanism is divided into a stamping mechanism, a forming mechanism, and a driving device according to its function. The driving device drives the rotating traction device to rotate the workpiece. The workpiece mold device positions the forming trajectory. The stamping mechanism applies pressure synchronously. The driving device provides power to the rotating traction device, and the rotating traction device acts directly on the workpiece. Combined with the pressure output of the stamping mechanism, a precise control chain is formed. The driving device can realize the micro-rotation of the workpiece through the rotating traction device. With the progressive pressure of the stamping mechanism, the sunroof slider and other devices are slowly deformed along the arc trajectory of the workpiece mold device, avoiding defects such as wrinkles and cracks caused by excessive force at one time.

[0009] Preferably, the stamping mechanism includes a stamping hydraulic cylinder, a connecting frame, a pressure roller, and a top beam. The top beam is fixedly connected to the top of the two sets of vertical plates, the base of the stamping hydraulic cylinder is fixedly connected to the bottom of the top beam, the connecting frame is fixedly connected to the working end of the stamping hydraulic cylinder, and the pressure roller is mounted on the connecting frame and rotatably connected to the connecting frame.

[0010] By adopting the above technical solution, the stamping hydraulic cylinder, as a power source, can provide continuous and powerful pressure, and the output pressure can be precisely adjusted through the hydraulic system. The stamping pressure can be flexibly adjusted according to the plastic deformation requirements, avoiding substandard forming due to insufficient pressure, or workpiece cracking and mold damage due to excessive pressure. The pressure roller is rotatably connected to the connecting frame. During the bending process, the pressure roller and the workpiece surface are subjected to rolling friction. Compared with the sliding friction of the fixed pressure block, this can significantly reduce damage to the workpiece surface. The rolling characteristics allow the pressure roller to achieve continuous and progressive bending with the traction of the workpiece.

[0011] Preferably, the workpiece mold device includes a support frame and an arc-shaped block, wherein the support frame is detachably connected to the base plate and the arc-shaped block is fixedly connected to the support frame.

[0012] By adopting the above technical solution, the arc-shaped block is fixedly connected to the support frame, and its arc-shaped contour directly serves as the reference for the bending and forming of the sunroof slide plate. It can accurately match the required bending curvature of the workpiece. Under the pressure of the pressure roller, the workpiece deforms along the surface of the arc-shaped block, which can ensure the consistency of curvature of the bending part and avoid problems such as curvature deviation, wrinkles or uneven deformation.

[0013] Preferably, the rotating traction device includes a speed reduction transmission assembly, a workpiece rotating assembly, and a workpiece connecting assembly. One end of the speed reduction transmission assembly is rotatably connected to the upright plate, and the other end of the speed reduction transmission assembly is connected to the workpiece rotating assembly. The workpiece rotating assembly is mounted on the support frame and rotatably connected to the support frame. The workpiece connecting assembly is detachably connected to the workpiece rotating assembly.

[0014] By adopting the above technical solution, the speed reduction transmission assembly can reduce the power of the drive device and increase the torque, so that the input speed and the output speed form a speed difference. The workpiece rotation assembly is rotatably connected to the support frame, which can drive the workpiece to rotate at multiple angles. In conjunction with the pressure roller of the stamping mechanism and the arc block of the workpiece mold device, the relative angle between the workpiece and the bending reference surface can be precisely adjusted. The workpiece connection assembly adopts a detachable design, and the length can be adjusted according to the shape of the workpiece bending to ensure stable traction of the workpiece.

[0015] Preferably, the workpiece rotating assembly includes a rotating shaft, two sets of first bearing devices, two sets of guide rods, and two sets of sliding bushings. The two sets of first bearing devices are respectively installed on both sides of the support frame. The rotating shaft is rotatably connected to the support frame through the two sets of first bearing devices. The two sets of guide rods are fixedly connected to the rotating shaft on the outside of the support frame. The two sets of sliding bushings are slidably connected to the two sets of guide rods respectively.

[0016] By adopting the above technical solution, two sets of first bearing devices are respectively installed on both sides of the support frame. The rotating shaft is rotatably connected to the support frame through the bearing. Two sets of guide rods are fixed on the rotating shaft on the outside of the support frame and rotate synchronously with the rotating shaft. The sliding bushing is slidably connected to the guide rod and can move freely along the axial direction of the guide rod, forming a compound motion mode of rotation and sliding. This allows the workpiece connected to the sliding bushing to rotate with the rotating shaft and adjust its axial position by the translation of the sliding bushing.

[0017] Preferably, the speed reduction transmission assembly includes a second bearing device, a drive shaft, a speed reducer, a driven shaft, and multiple sets of couplings. The second bearing device is mounted on a single set of the vertical plate. One end of the drive shaft is rotatably connected to the vertical plate via the second bearing device. The other end of the drive shaft is connected to the input end of the speed reducer via a single set of couplings. The two ends of the driven shaft are respectively connected to the output end of the speed reducer and the rotating shaft via two other sets of couplings.

[0018] By adopting the above technical solution, the reducer, as the core component, can convert the high-speed, low-torque power input from the drive shaft into a low-speed, high-torque output, achieving the effect that the driven shaft rotates a section for every one revolution of the drive shaft. This precisely matches the traction requirements of the rotating traction device for the workpiece. This conversion not only improves power utilization efficiency but also avoids the problem of excessive or insufficient power caused by mismatched power parameters, ensuring a smooth traction process.

[0019] Preferably, the workpiece connecting assembly includes a connecting rod, two sets of fixed tubes, and two sets of telescopic rods. The two sets of fixed tubes are respectively installed on two sets of sliding bushings, and the fixed tubes and sliding bushings are detachably connected. The two sets of telescopic rods are respectively installed inside the two sets of fixed tubes, and the telescopic rods are slidably connected to the fixed tubes. The two ends of the connecting rod are respectively fixedly connected to one end of the two sets of telescopic rods.

[0020] By adopting the above technical solution, the telescopic rod is slidably connected to the fixed tube and can extend and retract along the axial direction of the fixed tube. Then, the connecting rod drives the telescopic rods at both ends to adjust the overall length synchronously, which can adapt to workpieces of different lengths or widths. The telescopic rod can be pulled out from the fixed tube to increase the clamping span. For shorter workpieces, the telescopic rod can be retracted to shorten the span. Through the cooperation of the workpiece connecting component and the workpiece rotating component, multi-segment sliding is formed, which can cover the position requirements of the entire process from initial clamping to gradual deformation in the workpiece bending and forming.

[0021] Preferably, the driving device includes a driving hydraulic rod, a rack, a gear, and a sliding assembly. The rack is connected to the base plate via the sliding assembly and is slidably connected to the base plate. The gear is connected to the drive shaft on the outside of the upright plate, and the rack meshes with the gear for transmission. The base of the driving hydraulic rod is detachably connected to the base plate, and the working end of the driving hydraulic rod is fixedly connected to one end of the rack. The driving hydraulic rod provides power for the sliding of the rack.

[0022] By adopting the above technical solution, the driving hydraulic rod, as a power source, can provide continuous and stable thrust. The output force and movement speed can be precisely adjusted through the hydraulic system. For the large load traction required when bending the sunroof sliding plate, the driving hydraulic rod can easily meet the power requirements. At the same time, it can slow down or speed up the rack movement in real time according to the workpiece deformation progress. With the large reduction ratio design of one rotation of the drive shaft and one rotation of the driven shaft, the progressive control of the bending process can be realized. Furthermore, the driving hydraulic rod can control the reciprocating motion of the rack to reset the workpiece rotating components.

[0023] Preferably, the sliding assembly includes a linear guide rail and multiple sets of sliders. The linear guide rail is detachably connected to the base plate, and the multiple sets of sliders are mounted on the linear guide rail and slidably connected to the linear guide rail. A rack is mounted on the top of each slider, and the rack is detachably connected to the slider.

[0024] Preferably, a rotating baffle is provided on the drive shaft inside the upright plate, and the rotating baffle is fixedly connected to the drive shaft. A sensor device is provided on the upright plate near the drive shaft. The sensor device includes a first sensing sensor and a second sensing sensor. The first sensing sensor and the second sensing sensor are detachably connected to the upright plate along the circumference of the drive shaft. The first sensing sensor and the second sensing sensor are connected to the stamping hydraulic cylinder in the stamping mechanism.

[0025] By adopting the above technical solution, when the drive shaft drives the rotating baffle to rotate, the first sensing sensor is triggered first, and then the second sensing sensor is triggered. At this time, after receiving the signal, the control system drives the stamping hydraulic cylinder to perform periodic reciprocating extension and retraction actions to cooperate with the workpiece rotation of the rotating traction device. This allows the workpiece to rotate slowly with the traction device while the pressure roller applies pressure periodically, achieving a gradual coordination between rotation and bending. When the drive shaft drives the rotating baffle to rotate in the opposite direction, the signal from the second sensing sensor to the first sensing sensor changes, triggering the stamping hydraulic cylinder to rise to the top, causing the driven shaft to drive the rotating traction device to reset.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] The speed reduction transmission assembly can reduce the power of the drive device and increase the torque, so that the input speed and the output speed are different. The workpiece rotation assembly is rotatably connected to the support frame, which can drive the workpiece to rotate at multiple angles. In conjunction with the pressure roller of the stamping mechanism and the arc block of the workpiece mold device, the relative angle between the workpiece and the bending reference surface can be precisely adjusted. The workpiece connection assembly adopts a detachable design, and the length can be adjusted according to the shape of the workpiece bending to ensure stable traction of the workpiece.

[0028] When the drive shaft drives the rotating baffle to rotate, the first sensing sensor is triggered first, followed by the second sensing sensor. At this time, after receiving the signal, the control system drives the stamping hydraulic cylinder to perform periodic reciprocating extension and retraction actions, which coordinate with the rotation of the workpiece in the rotating traction device. This causes the workpiece to rotate slowly with the traction device, while the pressure roller applies pressure periodically, achieving a gradual coordination between rotation and bending. When the drive shaft drives the rotating baffle to rotate in the opposite direction, the signal from the second sensing sensor to the first sensing sensor changes, triggering the stamping hydraulic cylinder to rise to the top, causing the driven shaft to drive the rotating traction device to reset.

[0033] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0034] This application discloses a sunroof slider bending and forming device. (Refer to...)

The support frame 411 is installed on the bottom plate 1 between the two sets of upright plates 2 and is bolted to the bottom plate 1. The arc block 412 is fixedly connected to the top of the support frame 411. The pressure roller 33 in the stamping mechanism 3 cooperates with the arc block 412 to perform bending treatment on the workpiece.

[0035] Reference Figure 3The rotating traction device 42 includes a reduction transmission assembly 421, a workpiece rotating assembly 422, and a workpiece connecting assembly 423. The workpiece rotating assembly 422 includes a rotating shaft 4221, two sets of first bearing devices 4222, two sets of guide rods 4223, and two sets of sliding bushings 4224. Two sets of first bearing devices 4222 are installed on both sides of the support frame 411 and are bolted to the support frame 411. The two ends of the rotating shaft 4221 are installed on the support frame 411 through the first bearing devices 4222 and are rotatably connected to the support frame 411. The two sets of guide rods 4223 are fixedly connected to the rotating shaft 4221 on the outside of the support frame 411. The rotation of the rotating shaft 4221 drives the guide rods 4223 to rotate.

The other end of the drive shaft 4212 is connected to the input end of the speed reducer 4213 via a set of couplings 4215. Two other sets of couplings 4215 are installed at both ends of the driven shaft 4214. One end of the driven shaft 4214 is connected to the output end of the speed reducer 4213 via the couplings 4215, and the other end of the driven shaft 4214 is connected to the rotating shaft 4213 via the couplings 4215. One end of shaft 4221 is connected to the workpiece connecting assembly 423, which includes a connecting rod 4231, two sets of fixed tubes 4232, and two sets of telescopic rods 4233. The two sets of fixed tubes 4232 are respectively bolted to two sets of sliding bushings 4224. The fixed tubes 4232 slide by sliding the sliding bushings 4224 on the guide rods 4223. One end of each set of telescopic rods 4233 is slidably connected inside the two sets of fixed tubes 4232. Both ends of the connecting rod 4231 are fixedly connected to the other ends of the two sets of telescopic rods 4233. A hook is provided at one end of the workpiece. The hook cooperates with the connecting rod 4231. The workpiece is pulled by rotating shaft 4221.

[0037] A drive device 5 is installed on the base plate 1 on one side of the vertical plate 2 where the drive shaft 4212 is mounted. The drive device 5 includes a drive hydraulic rod 51, a rack 52, a gear 53, and a sliding assembly 54. The sliding assembly 54 includes a linear guide rail 541 and multiple sets of sliders 542. The linear guide rail 541 is bolted to the base plate 1. The multiple sets of sliders 542 are mounted on the linear guide rail 541 and are slidably connected to the linear guide rail 541. The rack 52 is bolted to the top of the multiple sets of sliders 542 and is slidably connected to the base plate 1 through the sliding assembly 54. The working end of the drive hydraulic rod 51 is fixedly connected to one end of the rack 52. The base of the drive hydraulic rod 51 is bolted to the base plate 1. The drive hydraulic rod 51 provides power for the sliding of the rack 52. The gear 53 is mounted on the drive shaft 4212 on the outside of the vertical plate 2 and meshes with the rack 52 for transmission.

[0038] Reference Figure 1 , Figure 2 and Figure 3 A rotating baffle 6 is provided on the drive shaft 4212 inside the upright plate 2. The rotating baffle 6 is fixed on the drive shaft 4212 and rotates with the drive shaft 4212. A sensor device 7 is provided on the upright plate 2 near the drive shaft 4212. The sensor device 7 includes a first sensing sensor 71 and a second sensing sensor 72. The first sensing sensor 71 and the second sensing sensor 72 are circumferentially connected to the upright plate 2 along the drive shaft 4212. The first sensing sensor 71 and the second sensing sensor 72 are connected to the stamping device. When the driving hydraulic rod 51 pushes the rack 52 to make the gear 53 rotate and drive the drive shaft 4212 to rotate, the rotating baffle 6 first passes the first sensing sensor 71 and then the second sensing sensor 72 when it rotates. When the sensor is activated, the driving hydraulic cylinder 31 performs a periodic reciprocating extension and retraction action. By cooperating with the drive shaft 4212 to rotate one revolution, the transmission is transmitted to the driven shaft 4214 through the reducer 4213, causing the driven shaft 4214 to rotate a small amplitude. The driven shaft 4214 is connected to the rotation traction device 42 through the coupling 4215, so that the rotation traction device 42 drives the workpiece to achieve continuous rotation and bending. When the driving hydraulic rod 51 pulls the rack 52 to make the gear 53 rotate, it drives the drive shaft 4212 to rotate in the opposite direction. When the rotating baffle 6 rotates, it first passes the second sensing sensor 72 and then the first sensor, and sends a signal, causing the stamping hydraulic cylinder 31 to be driven to rise away from the workpiece, and causing the rotation traction device 42 to rotate back to the starting position.

[0039] The working principle of the sunroof slider bending forming device in this application is as follows: the hook at one end of the workpiece is engaged with the connecting rod 4231 in the workpiece connecting assembly 423 to complete the initial fixation of the workpiece. The position of the fixing tube 4232 is adjusted by the sliding bushing 4224 on the guide rod 4223 to ensure that the workpiece connection is stable and the position is appropriate. The driving hydraulic rod 51 in the driving device 5 extends, pushing the rack 52 to slide along the base plate 1 under the guidance of the sliding assembly 54. The rack 52 meshes with the gear 53 on the drive shaft 4212. The sliding of the rack 52 drives the gear 53 to rotate, thereby causing the drive shaft 4212 to rotate. 12 rotates, and the drive shaft 4212 transmits power to the input end of the reducer 4213 through the coupling 4215. After being reduced in speed by the reducer 4213, the output end of the reducer drives the driven shaft 4214 to rotate through the coupling 4215. The driven shaft 4214 then drives the rotating shaft 4221 to rotate through the coupling 4215. When the rotating shaft 4221 rotates, the guide rods 4223 on both sides of the rotating shaft 4221 rotate. Through the sliding connection between the guide rods 4223, the sliding bushing 4224, the fixed tube 4232, and the telescopic rod 4233, the connecting rod 4231 rotates, causing the workpiece to be traction-processed around the arc. When the block 412 moves in an arc direction, the rotating baffle 6 on the drive shaft 4212 rotates synchronously. When the drive hydraulic rod 51 pulls the rack 52 to slide forward, the rotating baffle 6 passes the first sensor 71 and then the second sensor 72. The sensor device 7 sends a signal to the stamping mechanism 3, driving the stamping hydraulic cylinder 31 to perform a periodic reciprocating extension and retraction action. The stamping hydraulic cylinder 31 drives the connecting frame 32 and the pressure roller 33 to move up and down. The pressure roller 33 cooperates with the arc block 412 on the top of the support frame 411 in the forming mechanism 4. When the workpiece moves with the rotating traction device 42, During the process, the workpiece is continuously bent to gradually form a curved shape that matches the arc block 412. The hydraulic rod 51 is driven to pull the rack 52 to slide in the opposite direction, which drives the gear 53 and the drive shaft 4212 to rotate in the opposite direction. The rotating baffle 6 rotates in the opposite direction. When the signal is sent by the second sensor 72 and then the first sensor 71, the stamping hydraulic cylinder 31 drives the pressure roller 33 to rise away from the workpiece. The rotating traction device 42, driven by the reverse rotation of the drive shaft 4212, causes the workpiece connecting assembly 423 to rotate in the opposite direction through the transmission of the reduction transmission assembly 421, thus completing one processing cycle.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
