Description

Technical Field

[0001] This invention relates to the field of motorcycle wheel manufacturing technology, specifically to an automatic feeding and pre-forming equipment for motorcycle wheel production. Background Technology

[0002] The manufacturing process of wire-spoke motorcycle wheels involves three parts: the rim, the center hub, and the wire connection. Motorcycle rims are typically made from specific aluminum alloy profiles, the cross-section of which usually already possesses the basic outline of the rim. Through a rolling and extruding machine, the profile is gradually bent and shaped into a roughly circular, spirally arranged blank shape. This blank is then cut to obtain the material needed for each individual motorcycle wheel. At this stage, the ring shape is not yet closed, with the beginning and end misaligned by at least one notch the width of the profile.

[0003] The presence of this notch is a key design element in the manufacturing process, designed to facilitate material joining and shaping. Subsequently, the crucial joining stage begins: high-precision welding techniques such as TIG welding are used to firmly fuse the notch, forming a complete closed loop around the friction ring. After welding, excess solder and unevenness may remain at the weld seam. This requires meticulous grinding and polishing to ensure a smooth transition between the joint and the friction ring body, guaranteeing the overall structural strength and dynamic balance of the friction ring.

[0004] Authorization notice number CN222493020U discloses an aluminum wheel extrusion molding equipment. According to its specification and drawings, the aluminum wheel blank is placed on the lower die, the motor drives the main shaft to rotate, and the main shaft drives the lower die and the aluminum wheel blank to rotate; the clamping cylinder drives the upper die to move downward, and at the same time the left forming thrust cylinder and the right forming thrust cylinder drive the left forming roller and the right forming roller to jointly extrude the aluminum wheel blank to obtain a product with the same curve as the finished product.

[0005] However, the solution has certain limitations: 1. It cannot process long profiles into the specified kink shape; 2. How to ensure that long profiles are accurately rolled or pressed in the market is also a problem to be considered; 3. The solution cannot be used for forming processes of profiles of different specifications, and its adaptability is poor. Summary of the Invention

[0006] This invention addresses the aforementioned problems in the structural design of equipment used for the initial forming of profiles into the rolled shape of motorcycle rings. It proposes an automatic feeding and pre-forming equipment for motorcycle ring production, integrating automatic feeding, adaptive traction, and precision forming. Through flexible contact, multi-level guiding profile precision positioning, and modular quick-change design, it achieves efficient, non-destructive, and precise fully automatic pre-forming processing of long profiles of different specifications.

[0007] The objective of this invention is achieved through the following technical solution: an automatic feeding and pre-forming equipment for motorcycle ring production, comprising a support frame, a conveying mechanism disposed on the surface of the support frame, a profile forming mechanism formed by rolling on the outer side of the support frame, and a profile traction mechanism disposed on the support frame, wherein the rollers in the profile traction mechanism are used to pull and push the profile conveyed by the conveying mechanism into the roller conveying group of the profile forming mechanism.

[0008] Preferably, one side of the profile traction mechanism is close to the profile forming mechanism, and the other side of the profile traction mechanism is provided with a profile guiding component between the end of the conveying mechanism and the end of the conveying mechanism. The profile guiding component is used to guide the profile in a rolling manner and is provided on the bearing frame. Limiting components are also provided on both sides of the profile traction mechanism to limit the profile from deviating from the conveying direction of the conveying mechanism.

[0009] Preferably, the conveying mechanism includes a conveying support frame, bearing support seats, conveying rollers, chain drive wheels, a conveying chain, roller driven gears, a first drive motor, roller drive gears, a material support frame, and flexible support columns. The surface of the bearing frame is also provided with a conveying support frame. Bearing support seats are provided on the side walls of both ends of the conveying support frame. A conveying roller is provided inside between adjacent bearing support seats. The surface of each conveying roller is provided with several chain drive wheels. A conveying chain is provided on every two chain drive wheels located at both ends of the conveying support frame. At least one end of the conveying roller extends outward and is provided with a roller driven gear at that end. The bearing frame is also provided with a first drive motor. The end of the shaft of the first drive motor is provided with a roller drive gear. The roller drive gear and the roller driven gear are connected by a metal chain drive. The surface of the conveying chain is also provided with a material support frame. The interior of the material support frame is provided with several flexible support columns made of rubber.

[0010] Preferably, the profile guiding assembly includes several guide rollers, each of which is disposed between the profile traction mechanism and the conveying mechanism. Each guide roller is rotatably connected to the interior of the support frame. The support frame is also provided with cylinder support plates at both ends of the conveying support frame. The surface of the cylinder support plate is provided with a first cylinder. The piston rod of the first cylinder is perpendicular to the conveying direction of the metal chain, and the end of the piston rod is provided with a profile lifting plate.

[0011] Preferably, the profile traction mechanism includes a traction support frame, a first roller support plate, a first flexible roller, a traction driven gear, a motor support plate, a second drive motor, a traction drive gear, and a second flexible roller. The traction support frame has several first roller support plates arranged side-by-side inside. Several first flexible rollers are rotatably connected between adjacent first roller support plates. Each first flexible roller extends outward at one end and has several traction driven gears at that end. Adjacent traction driven gears are connected by a metal chain drive. The traction support frame also has a motor support plate inside, and a second drive motor is mounted on the motor support plate. The shaft end of the second drive motor has a traction drive gear. The traction drive gear and at least one traction driven gear are connected by a metal chain drive. The traction support frame also has several second flexible rollers inside. The axes of the first and second flexible rollers are parallel. The gap between the first and second flexible rollers increases the friction with the profile and pushes the profile into the roller conveyor group of the profile forming mechanism under the rotation of the first flexible roller.

[0012] Preferably, the traction support frame also has several second roller support plates arranged side by side inside, and several second flexible rollers are rotatably connected between adjacent second roller support plates. The top surface of the traction support frame is also provided with several second cylinders. The piston rod of each second cylinder passes through the top of the traction support frame and is connected to a cylinder lifting plate. The surface of the cylinder lifting plate is provided with several guide rod support seats. The surface of each second roller support plate is fixedly connected with a downward pressure guide rod. Each downward pressure guide rod is slidably connected inside the guide rod support seat. A spring is provided between the end of the downward pressure guide rod near the second roller support plate and the end of the guide rod support seat. The side of the traction support frame near the profile forming mechanism is also provided with a sensor support plate. The sensor support plate is provided with a photoelectric sensor. When the photoelectric sensor detects the profile, it is used to control the piston rod of the second cylinder to move to a designated position.

[0013] Preferably, the limiting assembly includes a fixed rod support seat, a guide fixed rod, and a limiting support rod. Several fixed rod support seats are provided on the side wall of the traction bearing frame near the guide roller. A guide fixed rod is provided between every two opposing fixed rod support seats. The axis of each guide fixed rod is parallel to the axis of the first flexible roller. Several limiting support rods perpendicular to the guide fixed rods are provided between adjacent guide fixed rods. Through guide holes are provided on the side walls at both ends of each limiting support rod. The guide holes of each limiting support rod are slidably connected to the surface of the guide fixed rod. Locking threaded holes are provided at both ends of each limiting support rod, and each locking threaded hole communicates with each guide through hole. A third flexible roller is also provided outside each limiting support rod. External bolts are threaded into the locking threaded holes until they are in contact with the surface of the guide fixed rod, after which the limiting support rod cannot slide relative to the guide fixed rod.

[0014] Preferably, the profile forming mechanism includes a forming support frame, a roller conveyor group, a conveyor guide roller, a servo electric cylinder, a forming drive wheel, guide rollers, a wheel support block, a forming driven wheel, and a rotary encoder. The forming support frame is provided with several roller conveyor groups for pressing and conveying the profiles. A conveyor guide roller is provided between every two roller conveyor groups. Each conveyor guide roller has several limiting plates on its surface. The forming support frame is also provided with a servo electric cylinder and a forming drive wheel. Several guide rollers are provided between the servo electric cylinder and the roller conveyor group. A push rod on the servo electric cylinder... The end is provided with a wheel support block that moves with the push rod. The wheel support block has a hollow interior and a forming driven wheel is hinged inside the wheel support block. The side wall of the wheel support block is also provided with a rotary encoder for monitoring the rotation of the forming driven wheel. The guide roller is rotatably connected to the forming support frame. Several protrusions on the surface of the guide roller and the forming driven wheel are adapted to the recessed inner grooves on the surface of the profile. The groove on the surface of the forming drive wheel is adapted to several protrusions on the bottom of the profile. When the forming drive wheel approaches the forming driven wheel, it can press down and curl the profile conveyed by the roller conveyor group into a circle.

[0015] Preferably, each of the roller conveyor groups includes a conveyor drive wheel and a conveyor driven wheel. The groove on the surface of the conveyor drive wheel is adapted to several protrusions on the bottom of the profile, and the several protrusions on the surface of the conveyor driven wheel are adapted to the recessed inner grooves on the surface of the profile. The forming support frame is also provided with a third drive motor and several gearboxes. Each gearbox is provided with several power output shafts and power input shafts. The power input shaft of at least one gearbox is connected to the rotating shaft of the third drive motor through a coupling. One power output shaft of any gearbox is connected to the power input shaft of another gearbox through a coupling. Another power output shaft of at least one gearbox is connected to the inside of the forming drive wheel, and the other power output shaft of the remaining gearbox is connected to the inside of the conveyor drive wheel. Each conveyor driven wheel is rotatably connected to the forming support frame. This arrangement is to realize the automatic rotation of the forming drive wheel and the conveyor drive wheel.

[0016] Preferably, the forming support frame is rotatably connected to several feeding guide rollers located below the forming drive wheel. The gap between the feeding guide rollers is used to guide the bent friction ring and prevent it from falling. The forming support frame is provided with a screw drive module on the side near the forming drive wheel. The slider on the screw drive module is equipped with a cutting machine. When the slider on the screw drive module moves to a designated position, the blade of the cutting machine can cut the profile. This setting is to limit the profile feeding process and automatically cut the bent profile.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The equipment organically integrates the conveying mechanism, profile guiding assembly, profile traction mechanism, and profile forming mechanism onto the same supporting frame, forming a continuous automated production line. This layout avoids the positioning errors and efficiency losses that occur when connecting multiple independent units in traditional equipment. Furthermore, through modular design—replaceable forming components and adjustable limit components—the equipment combines specialization with flexibility. 2. The height adjustment of the second flexible roller in the profile traction mechanism adopts a linkage design of cylinder, spring, and photoelectric sensor. When the photoelectric sensor detects that the profile is in place, the second cylinder drives the second flexible roller on the cylinder lifting plate to press down, while the spring provides buffer pressure, so that the pressure when the roller contacts the profile surface is adaptive, which avoids damaging the profile and ensures that the traction friction is maximized. The dynamic adjustment mechanism overcomes the defect of traditional rigid clamping devices that are prone to profile deformation, and improves the yield of the final friction ring. 3. The profile is continuously fed into the profile traction mechanism via the conveying mechanism. The first and second flexible rollers of the profile traction mechanism clamp the profile and stably push it forward into the forming mechanism, "feeding, forming, and cutting simultaneously": the forming process is dynamic; when the front end of the profile is pushed into the forming mechanism (such as the spinning roller) and begins to bend and form, its middle section is being pushed by the traction mechanism, while the tail end may still be on the conveying mechanism. The profile moves continuously throughout the entire process, and the forming action is completed during the movement of the profile. This design provides continuous feeding and traction mechanisms for processing long profiles. Theoretically, the length that can be processed is only limited by the length of the raw material profile, and the structure of the equipment itself (such as the continuous conveying and forming mechanism) is perfectly adapted to the processing needs of long profiles, bringing convenience to the production process. 4. The profile guiding assembly (guide rollers) plays a crucial bridging role between the conveying and traction mechanisms, smoothly transitioning the profile from horizontal conveying to the traction clamping point, preventing end sagging or tilting. The limiting assembly (third flexible rollers) constrains the profile from both sides before it enters the traction mechanism. By adjusting the gap between the two third flexible rollers, it can be ensured that the profile's centerline is perfectly aligned with the main conveying axis of the equipment, ensuring precise alignment. Finally, the first and second flexible rollers of the profile traction mechanism itself clamp the profile from above and below, providing driving force while preventing vertical jumping. At the entrance of the forming mechanism, the limiting plate on the conveying guide rollers performs a final lateral correction of the profile, ensuring it enters the spinning or rolling station with an accurate posture. This multi-stage guiding and limiting system lays a precise "track" for the profile, effectively solving the problem of misalignment that easily occurs after long-distance conveying of long profiles, ensuring forming accuracy. 5. This solution adapts to the shape of the profile by replacing a small number of specialized molding components, adapts to the width of the profile by quickly and manually adjusting the lateral limiting components, and adapts to the thickness of the profile by automatically adjusting the pressure. This combination method greatly improves the flexibility and production efficiency of the equipment while ensuring molding accuracy. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the embodiments illustrated in the accompanying drawings: like Figure 1 , Figure 2 and Figure 3 As shown, an automatic feeding and pre-forming equipment for motorcycle ring production includes a support frame 1 composed of several metal profiles fixedly connected to each other, and a conveying mechanism 5 disposed on the surface of the support frame 1. The conveying mechanism 5 includes a conveying support frame 51, bearing support seats 52, conveying roller shafts 53, chain drive wheels 54, conveying chains 55, roller shaft driven gears 56, a first drive motor 57, roller shaft drive gears 58, a material support frame 59, and flexible support columns 50. The surface of the bearing frame 1 is also provided with conveying support frames 51. Bearing support seats 52 are provided on the side walls at both ends of the conveying support frame 51. Conveying roller shafts 53 are located inside adjacent bearing support seats 52. Two chain drive wheels 54 are fixedly mounted on the surface of each conveying roller shaft 53. A conveying chain 55 is installed on a chain drive wheel 54 located at both ends of the conveying support frame 51. At least one conveying roller shaft 53 extends outward at its end and is provided with a roller shaft driven gear 56 at the end. The bearing frame 1 is also provided with a first drive motor 57. The end of the shaft of the first drive motor 57 is provided with a roller shaft drive gear 58. The roller shaft drive gear 58 and the roller shaft driven gear 56 are connected by a metal chain drive. The surface of the conveying chain 55 is also provided with a material support frame 59. The interior of the material support frame 59 is provided with several flexible support columns 50 made of rubber.

[0021] During implementation, the profile is placed on the surface of the flexible support column 50 on the material support frame 59; the shaft of the first drive motor 57 drives the roller shaft drive gear 58 to rotate simultaneously, and the roller shaft drive gear 58 drives the roller shaft driven gear 56 to rotate through the metal chain during rotation; the roller shaft driven gear 56 drives the chain drive wheel 54 during rotation; and the chain drive wheel 54 drives the conveying roller shaft 53 in the bearing support seat 52 on one side of the conveying support frame 51 to rotate; at the same time, the chain drive wheel 54 on the other side of the conveying support frame 51 and the conveying roller shaft 53 in the bearing support seat 52 rotate through the drive of the conveying chain 55. The two parallel conveyor chains 55 reciprocate while driving the conveyor rollers 53 at both ends of the conveyor support frame 51, thereby moving the material support frame 59 on the surface of the conveyor chain 55. The material support frame 59 then moves the profile on its surface. Therefore, the flexible support column 50 on the surface of the material support frame 59 is in direct contact with the profile to be conveyed. Since the flexible support column 50 is made of plastic material that can deform, it can increase friction while avoiding wear on the profile. Please continue to refer to the reference. Figure 3 and Figure 4In this embodiment, the supporting frame 1 is also provided with a profile traction mechanism 3, and a profile guide assembly 4 is provided between one side of the profile traction mechanism 3 and the end of the conveying mechanism 5. The profile guide assembly 4 includes a plurality of guide rollers 41, each guide roller 41 is disposed between the profile traction mechanism 3 and the conveying mechanism 5, and each guide roller 41 is rotatably connected to the inside of the supporting frame 1. The supporting frame 1 is also provided with cylinder support plates 42 at both ends of the conveying support frame 51. The surface of the cylinder support plate 42 is provided with a first cylinder 43, and the piston rod of the first cylinder 43 is perpendicular to the conveying direction of the metal chain and the end of the piston rod is provided with a profile lifting plate 44. With this setup, before the profile is placed on the flexible support column 50 on the material support frame 59, the piston rod of the first cylinder 43 extends first, making the height of the profile lifting plate 44 at the end of the piston rod relative to the bearing frame 1 greater than the height of the flexible support column 50 relative to the bearing frame 1. An external robotic arm or lifting gantry frame, in conjunction with a clamp, first places the profile on the surface of the profile lifting plate 44. Since the first cylinders 43 are respectively located at both ends of the conveying support frame 51, the profile lifting plate 44 at the end of the piston rod of each first cylinder 43 lifts both ends of the profile. Then, the piston rod of the first cylinder 43 gradually retracts, making the height of the profile lifting plate 44 relative to the bearing frame 1 gradually less than the height of the flexible support column 50 relative to the bearing frame 1, until the profile is stably placed on the surface of several flexible support columns 50.

[0022] Since the feed inlet of the profile traction mechanism 3 is aligned with the discharge outlet of the guide component 4, and the feed inlet of the guide component 4 is aligned with the discharge outlet of the conveying mechanism 5, the profile guide component 4 is used to roll guide the profile and is set on the bearing frame 1. Therefore, under the conveying of the material support frame 59 on the surface of the continuously moving conveyor chain 55, the profile will gradually be conveyed toward the surface of the guide roller 41; one end of the profile will gradually move to the surface of the guide roller 41, and the surface of the guide roller 41 will support and guide the profile; since the length of the combination of several guide rollers 41 is less than the length of the profile, the profile will gradually enter the interior of the profile traction mechanism 3 after passing several guide rollers 41; when the profile has not moved to the designated position inside the profile traction mechanism 3, the profile traction mechanism 3 will not work.

[0023] In this embodiment, the outer side of the supporting frame 1 is also provided with a profile forming mechanism 2 formed by rolling. The rollers in the profile traction mechanism 3 are used to pull and push the profiles conveyed by the conveying mechanism 5 into the roller conveying group 22 of the profile forming mechanism 2.

[0024] Please continue to refer to the reference. Figure 4 and Figure 5The profile traction mechanism 3 includes a traction support frame 31, a first roller support plate 32, a first flexible roller 33, a traction driven gear 34, a motor support plate 35, a second drive motor 36, a traction drive gear 37, and a second flexible roller 38. The traction support frame 31 has several first roller support plates 32 arranged side-by-side inside. Several first flexible rollers 33 are rotatably connected between adjacent first roller support plates 32. Each first flexible roller 33 extends outward at its end and has two traction driven gears 34 at that end. Adjacent traction driven gears 34 are connected by a metal chain drive. The traction support frame 31 also has a motor support plate 35 inside. A second drive motor 36 is mounted on the motor support plate 35. A traction drive gear 37 is mounted at the end of the shaft of the second drive motor 36. The traction drive gear 37 and at least one traction driven gear 34 are connected by a metal chain drive. The traction support frame 31 also has several second flexible rollers 38 inside. It should be noted that the height of the second flexible roller 38 can be automatically adjusted relative to the traction support frame 31, and the axes of the first flexible roller 33, the second flexible roller 38, and the guide roller 41 are all parallel. During implementation, as the profile passing through the guide roller 41 gradually enters the gap between the first flexible roller 33 and the second flexible roller 38, the height of the second flexible roller 38 can change. Therefore, only when the gap between the first flexible roller 33 and the second flexible roller 38 reaches a set distance is the gap used to increase the friction between the profile and the roller. Furthermore, the rotation of the first flexible roller 33 pushes the profile into the roller conveying group 22 of the profile forming mechanism 2. During the rotation of the first flexible roller 33, the shaft of the second drive motor 36 simultaneously drives the traction drive gear 37 to rotate. The traction drive gear 37 then drives a traction driven gear 34 at the end of the first flexible roller 33 to rotate via a metal chain, thereby causing the first flexible roller 33 to rotate simultaneously. At this time, the rotating first flexible roller 33 drives the adjacent first flexible roller 33 and the traction driven gear 34 to rotate simultaneously via another traction driven gear 34. Subsequently, the remaining adjacent first flexible rollers 33 also rotate simultaneously using the traction driven gear 34 and the metal chain. Ultimately, the rotation of each traction driven gear 34 and the first flexible roller 33 can push the gap profile located between the first flexible roller 33 and the second flexible roller 38 into the roller conveying group 22 of the profile forming mechanism 2. Please continue to refer to this. Figure 5The traction support frame 31 also has several second roller support plates 30 arranged side by side inside. Several second flexible rollers 38 are rotatably connected between adjacent second roller support plates 30. The top surface of the traction support frame 31 is also provided with several second cylinders 301. The piston rod of each second cylinder 301 passes through the top of the traction support frame 31 and is connected to a cylinder lifting plate 302. The surface of the cylinder lifting plate 302 is provided with several guide rod support seats 303. The surface of each second roller support plate 30 is fixedly connected to a lower... Each of the downward pressure guide rods 304 is slidably connected to the inside of the guide rod support seat 303. A spring 305 is provided between the end of the downward pressure guide rod 304 near the second roller support plate 30 and the end of the guide rod support seat 303. A sensor support plate 306 is also provided on the side of the traction bearing frame 31 near the profile forming mechanism 2. A photoelectric sensor 307 is provided on the sensor support plate 306. When the photoelectric sensor 307 detects the profile, it is used to control the piston rod of the second cylinder 301 to move to a designated position. Before the height of the second flexible roller 38 is automatically adjusted relative to the traction support frame 31, the gap height between the first flexible roller 33 and the second flexible roller 38 is greater than the height of the profile. At this time, the profile will gradually move above the photoelectric sensor 307 under the continuous conveying of the conveying mechanism 5. After the photoelectric sensor 307 detects that the profile has reached the set position: The height of the piston rod of the second cylinder 301 changes, thereby simultaneously causing the height of the cylinder lifting plate 302 to change; the cylinder lifting plate 302 then uses the spring 305 at the bottom of the guide rod support seat 303 to cause the height of the second roller support plate 30 to change until the second flexible roller 38 inside the second roller support plate 30 gradually adheres to the surface of the profile. To further adapt to the appropriate frictional force between the second flexible roller 38 and the first flexible roller 33 on the profile, as the second roller support plate 30 descends, the second flexible roller 38 applies a force to the profile. The second flexible roller 38 then receives a reaction force from the profile, which is transmitted to the second roller support plate 30. This causes the downward guide rod 304, which is fixedly installed on the second roller support plate 30, to slide relative to the inside of the guide rod support seat 303. The spring 305 then undergoes adaptive deformation. This allows the second flexible roller 38 and the first flexible roller 33 to obtain better downward pressure while avoiding damage to the profile surface.

[0025] In order to further limit the profile from shifting during the traction process and ensure the conveying accuracy, the profile traction mechanism 3 is provided with limiting components 6 on both sides to limit the profile from shifting relative to the conveying direction of the conveying mechanism 5. Please continue to refer to this. Figure 5The limiting assembly 6 includes a fixed rod support 61, a guide fixing rod 62, and a limiting support rod 63. The traction bearing frame 31 has several fixed rod support 61s on its side wall near the guide roller 41. A guide fixing rod 62 is provided between every two opposing fixed rod support 61s. The axis of each guide fixing rod 62 is parallel to the axis of the first flexible roller 33. Several limiting support rods 63 perpendicular to the guide fixing rods 62 are provided between adjacent guide fixing rods 62. The limiting support rods 63 have through-holes on their two end side walls. The guide through hole 631 of each of the limiting support rods 63 is slidably connected to the surface of the guide fixing rod 62. Each of the limiting support rods 63 has a locking thread hole 632 at both ends. Each locking thread hole 632 is connected to each guide through hole 631. A third flexible roller 64 is also provided on the outside of each limiting support rod 63. The external bolt is threaded into the locking thread hole 632 until it is in contact with the surface of the guide fixing rod 62. After that, the limiting support rod 63 cannot slide relative to the guide fixing rod 62. The limiting components 6 are respectively installed at the inlet and outlet of the profile traction mechanism 3; therefore, the profile must pass through the limiting components 6 when it enters the profile traction mechanism 3 through the profile guide component 4 and when it enters the roller conveyor group 22 of the profile forming mechanism 2 through the profile traction mechanism 3. The limiting components 6 can effectively limit the profile from deviating from the conveying direction of the conveying mechanism 5. During implementation, the two third flexible rollers 64, which are perpendicular to and parallel to the first flexible roller 33 and the second flexible roller 38, restrict the profile sidewall direction from shifting; at the same time, the first flexible roller 33, the second flexible roller 38 and the third flexible roller 64 are all made of polyurethane, thereby avoiding scratches on the profile. Since the widths of profiles of different specifications vary, it is necessary to adjust the gap between adjacent third flexible rollers 64. During the adjustment of the position of each third flexible roller 64, the bolts inside the locking threaded holes 632 at the top and bottom of the corresponding limiting support rod 63 can be loosened first. Then, the limiting support rod 63 is slid so that the guide through hole 631 slides on the surface of the guide fixing rod 62. The third flexible roller 64 changes with the position of the limiting support rod 63. After sliding to the designated position, the bolts inside the locking threaded holes 632 are tightened again. After the end of the bolt is attached to the surface of the guide fixing rod 62, the limiting support rod 63 cannot slide relative to the guide fixing rod 62, thereby completing the position adjustment of each third flexible roller 64.

Several guide rollers 26 are also provided between the servo electric cylinder 24 and the roller conveyor groups 22. The push rod end of the 4 is provided with a wheel support block 241 that moves with the push rod. The wheel support block 241 is hollow and a forming driven wheel 27 is hinged inside the wheel support block 241. The side wall of the wheel support block 241 is also provided with a rotary encoder 28 for monitoring the rotation of the forming driven wheel 27. The guide roller 26 is rotatably connected to the forming support frame 21. Several protrusions on the surface of the guide roller 26 and the forming driven wheel 27 are adapted to the recessed inner groove on the surface of the profile. The groove on the surface of the forming drive wheel 25 is adapted to several protrusions on the bottom of the profile. When the forming drive wheel 25 approaches the forming driven wheel 27, it can press down and curl the profile conveyed by the roller conveyor group 22 into a circle.

[0027] During implementation, when the profile is pushed by the rotation of the first flexible roller 33, the profile in the gap between the first flexible roller 33 and the second flexible roller 38 is first pulled and pushed into the roller conveyor group 22; the drive generated by the roller conveyor group 22 can continue to convey the profile, so that the profile passes through the surfaces of other roller conveyor groups 22, conveying guide rollers 23, guide rollers 26 and forming drive wheels 25 in sequence. Since the width between the limiting plates 231 on the surface of the conveying guide roller 23 is exactly matched with the width of the profile, there will be no reverse offset during the conveying process, and the profile is limited in the side wall direction; at the same time, the roller conveying group 22 limits the profile in the surface and top directions. Whenever the profile reaches the surface of the forming drive wheel 25, the servo electric cylinder 24 pushes the wheel support block 241 downward until the forming driven wheel 27 inside the wheel support block 241 exerts downward pressure on the profile. During the downward pressure process, the forming driven wheel 27 can also rotate relative to the inside of the wheel support block 241. Under the action of the downward pressure and the rotational force generated by the forming drive wheel 25 and the roller conveyor group 22, the profile gradually bends downward. The rotary encoder 28 collects the rotational data of the forming driven wheel 27 and promptly determines whether the material required for the molding ring has reached the set length. The bent profile gradually bends into a ring shape; since the profile itself already has a specific shape before forming, several protrusions on the surfaces of the guide roller 26 and the forming driven roller 27 are adapted to the recessed inner grooves on the surface of the profile, and the grooves on the surface of the forming drive roller 25 are adapted to several protrusions on the bottom of the profile; this design not only limits the offset of the surface and bottom of the profile, but also prevents damage to the profile; In this embodiment, three feeding guide rollers 211 are rotatably connected to the molding support frame 21 below the molding drive wheel 25. A screw drive module 7 is provided on the side of the molding support frame 21 near the molding drive wheel 25, and a cutting machine 71 is provided on the slider of the screw drive module 7.

[0028] Meanwhile, the bottom of the bent profile end gradually fits against the surface of the feeding guide roller 211. Since several feeding guide rollers 211 are arranged in a triangular pattern on the side wall of the forming support frame 21, the gap between the feeding guide rollers 211 is used to guide the bending forming ring and limit the bending forming ring from falling off. When the profile bending process is completed under the information acquisition of the rotary encoder 28, the slider on the screw drive module 7 moves to the designated position, and finally the blade of the cutting machine 71 can cut off the end of the profile. The industrial robot uses the gripper to grab the profile to the next process.

[0029] In this embodiment, each roller conveyor group 22 includes a conveyor drive wheel 221 and a conveyor driven wheel 222. The groove on the surface of the conveyor drive wheel 221 is adapted to a plurality of protrusions on the bottom of the profile, and the plurality of protrusions on the surface of the conveyor driven wheel 222 are adapted to the recessed inner groove on the surface of the profile. Similarly, this design can not only generate driving force but also limit the displacement of the surface and bottom of the profile without damaging the profile. The molding support frame 21 is also provided with a third drive motor 29 and a plurality of gearboxes 20. Each gearbox 20 is provided with a plurality of power output shafts 202 and power input shafts 201. The power input shaft 201 of at least one gearbox 20 is connected to the rotating shaft of the third drive motor 29 through a coupling. One power output shaft 202 of any gearbox 20 is connected to the power input shaft 201 of another gearbox 20 through a coupling. The other power output shaft 202 of at least one gearbox 20 is connected to the inside of the molding drive wheel 25 and the other power output shaft 202 of the remaining gearbox 20 is connected to the inside of the conveying drive wheel 221. Each conveying driven wheel 222 is rotatably connected to the molding support frame 21. During the rotation of the shaft of the third drive motor 29, the power input shaft 201 of one of the gearboxes 20 is first driven. At this time, one of the two power output shafts 202 of the gearbox 20 is used to drive the forming drive wheel 25 to rotate, and the other drives the power input shaft 201 of the next gearbox 20 to rotate through the coupling. In the subsequent gearboxes 20, one of the two power output shafts 202 is used to drive the conveying drive wheel 221 to rotate, and the other drives the power input shaft 201 of the next gearbox 20 to rotate through the coupling. This process is repeated. The last gearbox 20 only needs one power output shaft 202, and the other power output shaft 202 will be sealed with an end cover.

[0030] It should be noted that this solution can process profiles of different specifications without replacing any parts of the profile traction mechanism 3, profile guide assembly 4, and conveying mechanism 5. For the profile forming mechanism 2, it is necessary to replace the roller conveyor group 22, forming drive wheel 25, guide roller 26, and forming driven wheel 27. However, it is not necessary to replace the screw drive module 7, servo electric cylinder 24, conveying guide roller 23, and unloading guide roller 211. The gap between the first flexible roller 33 and the second flexible roller 38 is automatically adapted and adjusted, and the gap between the adjacent third flexible roller 64 can be manually adjusted, so that one device can complete the conveying and forming of profiles of different specifications.

[0031] Working principle and usage of this invention: The piston rods of the first cylinders 43 located at both ends of the conveying support frame 51 extend, causing the height of the profile support plate 44 at its top to exceed the height of the flexible support column 50.

[0032] The long profile is placed on the profile support plates 44 at both ends by an external robotic arm or lifting gantry.

[0033] The piston rod of the first cylinder 43 slowly retracts, and the profile lifting plate 44 descends accordingly. The profile is smoothly transferred and finally placed completely on the multiple flexible support columns 50 of the material support frame 59. The flexible support columns 50 both protect the surface of the profile and increase the friction.

[0034] The first drive motor 57 starts, driving the roller shaft drive gear 58 to rotate, which in turn drives the roller shaft driven gear 56 via a metal chain.

[0035] The driven gear 56 of the roller shaft drives the conveyor roller shaft 53 to rotate, and the chain drive wheel 54 on the conveyor roller shaft 53 rotates accordingly, thereby driving the two conveyor chains 55 to reciprocate synchronously.

[0036] The material support frame 59, fixed on the conveyor chain 55, drives the profile on it to move in the direction of the profile traction mechanism 3.

[0037] After the front end of the profile leaves the conveying mechanism 5, it enters the profile guiding assembly 4, which consists of several guide rollers 41. The guide rollers 41 roll and support the profile, allowing it to smoothly transition to the entrance of the profile traction mechanism 3.

[0038] The front end of the profile passes through the limiting component 6 at the entrance (the gap left between the two third flexible rollers 64) and enters the area inside the gap between the first flexible roller 33 and the second flexible roller 38 of the profile traction mechanism 3.

[0039] When the front end of the profile moves above the photoelectric sensor 307, the sensor sends a signal. The piston rod of the second cylinder 301 moves, pushing the cylinder lifting plate 302 down, which in turn drives the second roller support plate 30 and the second flexible roller 38 on it to press down through the spring 305 and the downward guide rod 304.

[0040] The second flexible roller 38 presses against the surface of the profile, and the deformation of the spring 305 provides cushioning, ensuring that sufficient clamping friction is applied to the profile without damaging the surface. At this time, the profile is clamped between the first flexible roller 33 and the second flexible roller 38.

[0041] The second drive motor 36 starts, driving the traction drive gear 37, which in turn drives all the traction driven gears 34 to rotate synchronously via a metal chain, thereby driving all the first flexible rollers 33 to rotate. Relying on friction, the first flexible rollers 33 forcefully push the profile into the downstream profile forming mechanism 2.

[0042] At the inlet and outlet of the traction mechanism, the third flexible roller 64 of the limiting assembly 6 constrains the profile from both sides, ensuring that the profile moves in a straight line without deviating. The position of the limiting support rod 63 on the guide fixing rod 62 can be adjusted to accommodate profiles of different widths.

[0043] The third drive motor 29 transmits power synchronously to all conveying drive wheels 221 and forming drive wheels 25 through multiple gearboxes 20 and couplings, ensuring consistent conveying speed.

[0044] The profile first enters the roller conveyor group 22 of the profile forming mechanism 2. The conveyor drive wheel 221 and the conveyor driven wheel 222 continue to convey the profile and provide initial constraints through the precise fit between their surfaces and the concave and convex shapes of the profile.

[0045] The profile is fed onto the forming drive wheel 25. The servo electric cylinder 24 and the pre-push wheel support block 241 and the forming driven wheel 27 hinged therein press down, so that the profile can be pressed onto the forming drive wheel 25 when the subsequent profile passes by.

[0046] Under the combined action of the rotational drive of the forming drive wheel 25 and the downward pressure of the forming driven wheel 27, the profile is gradually bent into a ring shape. During the bending process, the guide roller 26 and the feeding guide roller 211 support and guide the formed part.

[0047] A rotary encoder 28 mounted on the wheel support block 241 monitors the number of rotations of the forming driven wheel 27 in real time, thereby accurately calculating the length of the fed profile. When the length reaches the predetermined value, a signal is sent.

[0048] The lead screw drive module 7 drives the cutting machine 71 to move to the designated position and cut the profile. A preform of a mortise ring is completed and falls onto the feeding guide roller 211, where it is picked up by an industrial robot for the next process.

[0049] Changeover and adjustment methods: Based on the cross-sectional shape of the new material, replace the conveying drive wheel 221, conveying driven wheel 222, forming drive wheel 25, guide roller 26 and forming driven wheel 27 in the profile forming mechanism 2 to ensure that the protrusions and grooves on their surfaces perfectly match the new material.

[0050] Loosen the bolts in the locking threaded holes 632 on the limiting support rod 63 in the limiting assembly 6, slide the limiting support rod 63 to make the gap between the third flexible rollers 64 on both sides adapt to the width of the new material, and then tighten the bolts again.

[0051] The thickness variation of the profile is automatically compensated by the second cylinder 301 and spring 305 system of the profile traction mechanism 3, without the need for manual pressure adjustment.

[0052] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
