Description

Technical Field

[0001] This invention relates to wheel rim shaping, and more specifically, to a wheel rim spoke shaping device. Background Technology

[0002] Wheel spokes are the part that connects the rim and hub, mainly serving a supporting and fixing function. During the wheel manufacturing process, the wheel rim and spokes are prone to deformation due to processing techniques, transportation, and other factors. Deformed wheels not only affect the vehicle's appearance but also threaten its stability and safety. Currently, they are mostly repaired using shaping devices.

[0003] There are many existing technologies for plastic surgery devices, such as:

[0004] Chinese Patent Publication No. CN120169918A discloses a steel wheel spoke stamping die, including a support platform, a lower die base disposed on the support platform, a load-bearing detection component mounted on the support platform for bearing the lower die base and detecting its position, a press mounted on the top of the support platform, an upper die base drive mounted on the output end of the press, the upper die base and the lower die base cooperating for stamping wheel spoke workpieces, and a drive component mounted on the front of the support platform for driving the lower die base to revolve and rotate to retract. This invention utilizes the cooperative use of the lower die base and the drive component. The drive component can drive multiple lower die bases to rotate, thereby enabling multiple lower die bases to cooperate with the upper die base to stamp wheel spokes. Furthermore, when the drive component drives the lower die base to rotate and separate from the upper die base, it can also cause the lower die base to rotate one revolution, automatically unloading the material, thus improving the efficiency of wheel spoke stamping production.

[0005] However, some problems still exist in actual use:

[0006] 1. Currently, when traditional presses are used to trim wheel spokes, they usually need to go through the steps of loading, shaping, unloading, and loading again. The unloading and reloading processes are quite time-consuming and affect the shaping efficiency of wheel spokes.

[0007] 2. When the wheel spokes are finished, because the wheel is arc-shaped and fits the lower mold, the operators need to use auxiliary tools such as pry bars to peel the wheel spokes off the mold due to the adsorption force and lateral friction generated by the contact of the curved surfaces. This not only increases the labor intensity, but may also cause the wheel spoke edges to warp due to uneven force, resulting in the need for secondary finishing.

[0008] In view of this, we propose a wheel rim spoke shaping device. Summary of the Invention

[0009] The purpose of this invention is to provide a wheel rim spoke shaping device to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, the present invention provides a wheel rim spoke shaping device, comprising a machine base, a protective cover above the machine base, guide rollers on both sides of the protective cover surface, a shaping component inside the protective cover, a first motor on one side of the protective cover, an output shaft of the first motor passing through the protective cover and having a first lead screw at its end, a moving platform on the surface of the first lead screw, a cylinder on the surface of the moving platform, an upper die on the piston rod at the end of the cylinder, guide rods on both sides of the upper die, a feeding component on the surface of the machine base, the feeding component driving the wheel spoke to be shaped to move below the shaping component, adjustment components on both sides of the feeding component surface, the adjustment components being used to limit and fix wheel spokes of different sizes, and a unloading component at the end of the feeding component, after the wheel spoke is shaped, the unloading component automatically pushes the wheel spoke away from the feeding component.

[0011] As a further improvement to this technical solution, the feeding assembly includes a servo motor located below the machine base. The servo motor passes through the machine base and has a rotating gear at its end. A first toothed plate and a second toothed plate are respectively provided on both sides of the rotating gear. The first toothed plate and the second toothed plate move on the side wall of the guide roller. When the rotating gear rotates, the first toothed plate and the second toothed plate move relative to each other. The first toothed plate and the second toothed plate have the same structure.

[0012] As a further improvement to this technical solution, both the first toothed plate and the second toothed plate are provided with a lower mold. The lower mold is provided with guide grooves on both sides, and the guide grooves are adapted to guide rollers. The lower mold is used to place wheels.

[0013] As a further improvement to this technical solution, a support plate is provided inside the lower mold, and an elastic telescopic rod is provided between the support plate and the bottom of the lower mold, so that the support plate can be pressed and slid vertically against the inner wall of the lower mold.

[0014] As a further improvement to this technical solution, the adjustment component includes hollow columns on both sides of the first toothed plate, with grooves on both sides of the hollow columns, a long rod slidingly mounted on the inner wall of the hollow columns, a telescopic spring between the hollow columns and the long rod, and a clamping plate at the end of the long rod. The clamping plate is adjusted by the force of the telescopic spring to position the lower mold placed at its center, so that it is at the center of the clamping plate.

[0015] As a further improvement to this technical solution, the bottom of the long rod is provided with a locking tooth, which slides on the inner wall of the groove. A fixing component is provided above the locking tooth, which is used to fix the clamping position of the clamping plate.

[0016] As a further improvement to this technical solution, the fixing component includes a frame plate disposed above the hollow column. A second motor is provided on the top of the frame plate. A main gear is provided at the output end of the second motor. A secondary gear is provided on both sides of the main gear. A second lead screw is provided at the end of each secondary gear. When the secondary gear rotates, it drives the second lead screw to rotate coaxially.

[0017] As a further improvement to this technical solution, a movable plate is provided on the surface of the second lead screw. When the second lead screw rotates, it drives the movable plate to move in the horizontal direction. A toothed plate is provided at the bottom of the movable plate. When the toothed plate moves relative to the toothed plate, it clamps and fixes the toothed plate.

[0018] As a further improvement to this technical solution, the feeding assembly includes a rotating rod disposed inside the lower mold. The end of the rotating rod passes through the lower mold and is provided with a fixed gear. An eccentric wheel is provided on the surface of the rotating rod. The eccentric wheels are arranged in an array on the surface of the rotating rod. A torsion spring is provided on the surface of the rotating rod. The two ends of the torsion spring are respectively fixed to the eccentric wheel and the inner wall of the lower mold.

[0019] As a further improvement to this technical solution, a rack is slidably provided on one side of the fixed gear, and a pressure plate is provided at the end of the rack. The pressure plate is located below the guide grooves on both sides of the lower mold.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In this wheel rim spoke shaping device, the upper mold is moved vertically downward by a control cylinder, so that the upper mold performs pressure shaping on the spokes placed inside the lower mold. When the first toothed plate moves into the protective cover, the second toothed plate moves in the opposite direction to the first toothed plate. At this time, the second toothed plate moves away from the upper mold. By feeding material into the lower mold inside the surface of the second toothed plate, when the lower mold on the surface of the first toothed plate has finished shaping and moves away from the second toothed plate, the lower mold placed on the surface of the second toothed plate moves to below the upper mold for automatic shaping, thereby improving the shaping efficiency of the spokes.

[0022] 2. In this wheel rim spoke shaping device, when the clamping plate clamps and limits the side wall of the lower mold, the output shaft of the second motor is controlled to drive the main gear to rotate coaxially. When the main gear rotates, it drives the secondary gear to mesh and rotate. When the secondary gear rotates, it drives the second lead screw to rotate coaxially. The moving plate on the surface of the second lead screw moves relative to the main gear. Since the end of the moving plate is equipped with a toothed plate, when the toothed plate moves to the toothed end, the second motor is controlled to stop rotating. At this time, the toothed plate limits and fixes the toothed end, thereby ensuring that the spokes placed inside the lower mold remain stable when subjected to force, thus ensuring the shaping effect of the spokes.

[0023] 3. In this wheel rim spoke shaping device, when the spoke shaping is completed, the cylinder drives the upper mold to move upward in the vertical direction. At this time, the external force on the torsion spring gradually disappears, and the rotating rod is driven by the torsion spring to rotate the eccentric wheel coaxially. When the eccentric wheel rotates, it supports the bottom of the support plate until the eccentric end of the eccentric wheel rotates to 90° and is perpendicular to the bottom of the support plate. At this time, the shaped spoke follows the rotation of the eccentric wheel and moves vertically upward along the inner wall of the lower mold, so that the wheel moves to the outside of the lower mold, which facilitates the quick unloading of the shaped wheel spoke.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0042] The purpose of this embodiment is to provide a wheel rim spoke shaping device, see reference. Figures 1-9 As shown, the machine includes a machine base 100, a protective cover 101 above the machine base 100, guide rollers 102 on both sides of the surface of the protective cover 101, and a shaping assembly inside the protective cover 101. The shaping assembly includes a first motor 200 located on one side of the protective cover 101, the output shaft of the first motor 200 passing through the protective cover 101 and having a first lead screw 201 at its end, a moving table 202 on the surface of the first lead screw 201, a cylinder 203 on the surface of the moving table 202, and a piston rod at the end of the cylinder 203. The upper mold 204 has guide rods 205 on both sides. The surface of the machine base 100 is provided with a feeding component 300. The feeding component 300 drives the wheel spokes with shaping to move below the shaping component. The surface of the feeding component 300 is provided with adjustment components 400 on both sides. The adjustment components 400 are used to limit and fix wheel spokes of different sizes. The end of the feeding component 300 is provided with a feeding component 500. After the wheel spokes are shaped, the feeding component 500 automatically pushes the wheel spokes away from the feeding component 300.

[0043] When shaping wheel spokes, the process typically involves loading, shaping, unloading, and reloading. The unloading and reloading processes are time-consuming, impacting the shaping efficiency. Therefore, the feeding assembly 300 includes a servo motor 301 located below the machine base 100. The servo motor 301 passes through the machine base 100 and has a rotating gear 302 at its end. The rotating gear 302 has a first toothed plate 303 and a second toothed plate 304 on both sides. The first toothed plate 303 and the second toothed plate 304 move along the side wall of the guide roller 102. When the rotating gear 302 rotates, the first toothed plate 303... 3. The first toothed plate 303 and the second toothed plate 304 move relative to each other. The first toothed plate 303 and the second toothed plate 304 have the same structure. Both the first toothed plate 303 and the second toothed plate 304 are provided with a lower mold 305. The lower mold 305 is provided with guide grooves on both sides. The guide grooves are adapted to the guide roller 102. The lower mold 305 is used to place the wheel. The lower mold 305 is provided with a support plate 307 inside. An elastic telescopic rod 306 is provided between the support plate 307 and the bottom of the lower mold 305. Pressing the support plate 307 slides vertically on the inner wall of the lower mold 305. When the wheel spoke is shaped, the output end of the servo motor 301 is controlled to drive the rotating teeth. When wheel 302 rotates, the rotating gear 302 drives the first toothed plate 303 to move into the protective cover 101. When the first toothed plate 303 moves, it adheres to the side wall of the guide roller 102, reducing sliding friction. The lower mold 305 on the surface of the first toothed plate 303 drives the wheel spokes to move. At the same time, the first motor 200 drives the first lead screw 201 to rotate. When the first lead screw 201 rotates, the moving table 202 moves horizontally on its surface. When the cylinder 203 moves above the first toothed plate 303, the cylinder 203 drives the upper mold 204 to move downward in the vertical direction, so that the upper mold 204 is placed on top of the first toothed plate 303. The spokes inside the lower die 305 are pressure-shaped. When the first toothed plate 303 moves into the protective cover 101, the second toothed plate 304 moves in the opposite direction to the first toothed plate 303. At this time, the second toothed plate 304 moves away from the upper die 204. By feeding material into the lower die 305 on the surface of the second toothed plate 304, when the lower die 305 on the surface of the first toothed plate 303 has finished shaping and moves away from the second toothed plate 304, the lower die 305 placed on the surface of the second toothed plate 304 moves to the lower die 204 for automatic shaping, thereby improving the shaping efficiency of the spokes.

[0044] Due to the different spoke sizes, the forming mold needs to be changed frequently. Traditional molds are fixed to the worktable with bolts, and the disassembly process is labor-intensive. Therefore, the adjustment assembly 400 includes hollow columns 401 on both sides of the first toothed plate 303. The hollow columns 401 have grooves on both sides. A long rod 402 slides on the inner wall of the hollow columns 401. A telescopic spring 403 is provided between the hollow columns 401 and the long rod 402. A clamping plate 404 is provided at the end of the long rod 402. The clamping plate 404 is adjusted by the force of the telescopic spring 403 to make the lower mold 305 placed at its center, so that it is in the clamping plate 404. At the center, when replacing different lower molds 305, by pushing the clamping plate 404 to move to both sides, the clamping plate 404 is pressured to drive the long rod 402 to slide on the inner wall of the hollow column 401 and squeeze the telescopic spring 403, placing the lower mold 305 between the clamping plates 404. When the pressure on the clamping plate 404 is stopped, the hollow column 401 is subjected to the restoring force of the telescopic spring 403, causing the clamping plate 404 to move relative to each other and clamp and limit the lower mold 305, so that the lower mold 305 is in the center of the clamping plate 404. This avoids the need to disassemble multiple fixing bolts of the lower mold 305 and reduces the labor intensity of the operators.

[0045] When shaping the spokes placed inside the lower die 305, the spokes are subjected to significant pressure. To prevent uneven force distribution on the lower die 305 and its sliding on the surface of the first toothed plate 303, which would affect the shaping effect, a retaining tooth 405 is provided at the bottom of the long rod 402. The retaining tooth 405 slides on the inner wall of the groove. A fixing component is provided above the retaining tooth 405 to fix the clamping position of the clamping plate 404. The fixing component includes a frame plate 406 located above the hollow column 401. A second motor 407 is provided at the top of the frame plate 406. A main gear 408 is provided at the output end of the second motor 407. A secondary gear 409 is provided on both sides of the main gear 408. A second lead screw 410 is provided at the end of each secondary gear 409. When the secondary gear 409 rotates, it drives the second lead screw 410 to rotate coaxially. A movable plate 411 is provided on the surface of the second lead screw 410. When the second lead screw 410 rotates, it drives... The movable plate 411 moves horizontally. The bottom of the movable plate 411 is provided with a toothed plate 412. When the toothed plate 412 moves relative to the tooth, it clamps and fixes the tooth 405. When the clamping plate 404 clamps and limits the side wall of the lower mold 305, the output shaft of the second motor 407 is controlled to drive the main gear 408 to rotate coaxially. When the main gear 408 rotates, it drives the auxiliary gear 409 to mesh and rotate. When the auxiliary gear 409 rotates, it drives the second lead screw 410 to rotate coaxially. The movable plate 411 on the surface of the second lead screw 410 moves relative to the toothed plate 411. Since the end of the movable plate 411 is provided with a toothed plate 412, when the toothed plate 412 moves to the end of the tooth 405, the second motor 407 is controlled to stop rotating. At this time, the toothed plate 412 limits and fixes the tooth 405, thereby ensuring that the spokes placed inside the lower mold 305 remain stable when subjected to force, thereby ensuring the shaping effect of the spokes.

[0046] Meanwhile, when replacing the lower mold 305, pressing the clamping plate 404 causes the long rod 402 to slide on the inner wall of the hollow column 401. At this time, the output shaft of the second motor 407 is controlled to drive the main gear 408 to rotate. When the main gear 408 rotates, it drives the secondary gear 409 to mesh and rotate. The second lead screw 410 at the end of the secondary gear 409 rotates coaxially. When the second lead screw 410 rotates, the moving plate 411 on its surface moves relative to it and limits the locking teeth 405, so that the clamping plate 404 remains stationary when it is in a far-away state. This makes it easier to place the lower mold 305 to be replaced between the clamping plates 404, thereby improving the replacement efficiency of the lower mold 305.

[0047] When the wheel spokes are finished, the wheel is arc-shaped and fits the lower die 305, making it inconvenient to cut. Therefore, the cutting assembly 500 includes a rotating rod 501 located inside the lower die 305. The end of the rotating rod 501 passes through the lower die 305 and is equipped with a fixed gear 504. An eccentric wheel 502 is provided on the surface of the rotating rod 501, and the eccentric wheels 502 are arranged in an array on the surface of the rotating rod 501. A torsion spring 503 is provided on the surface of the rotating rod 501. Spring 503 is fixed at both ends to the eccentric wheel 502 and the inner wall of the lower die 305, respectively. A rack 505 is slidably provided on one side of the fixed gear 504. A pressure plate 506 is provided at the end of the rack 505. The pressure plate 506 is located below the guide grooves on both sides of the lower die 305. When the spokes are trimmed, cylinder 203 drives the upper die 204 to move downward in the vertical direction. The guide rods 205 on both sides of the upper die 204 slide on the inner wall of the guide groove. When the guide rods 205 pass through the guide groove, they squeeze the pressure plate 506. The pressure plate 506 drives the rack 505 to slide on one side of the fixed gear 504. When the rack 505 moves, it drives the fixed gear 504 to mesh and rotate. The fixed gear 504 drives the rotating rod 501 to rotate to 90° and stop rotating. At this time, the eccentric wheel 502 on the surface of the rotating rod 501 is in a horizontal state with the support plate 307. When the spoke trimming is completed, the cylinder 203 drives the upper mold 204 to move upward in the vertical direction. At this time, the external force on the torsion spring 503 gradually disappears. The rotating rod 501 is driven by the force of the torsion spring 503 to drive the eccentric wheel 502 to rotate coaxially. When the eccentric wheel 502 rotates, it supports the bottom of the support plate 307 until the eccentric end of the eccentric wheel 502 rotates to 90° and is perpendicular to the bottom of the support plate 307. At this time, the trimmed spokes follow the rotation of the eccentric wheel 502 and move vertically upward along the inner wall of the lower mold 305, so that the wheel moves to the outside of the lower mold 305, which facilitates the quick unloading of the trimmed wheel spokes.

[0048] In practical use, during spoke shaping, the output of the servo motor 301 drives the rotating gear 302 to rotate. When the rotating gear 302 rotates, it moves the first toothed plate 303 inside the protective cover 101. As the first toothed plate 303 moves, it adheres to the side wall of the guide roller 102, reducing sliding friction. The lower die 305 on the surface of the first toothed plate 303 drives the spokes to move. Simultaneously, the first motor 200 drives the first lead screw 201 to rotate. When the first lead screw 201 rotates, the moving table 202 moves horizontally on its surface. When the cylinder 203 moves above the first toothed plate 303, the cylinder 203 drives the upper die 204 along... The upper die 204 moves vertically downward, causing the upper die 204 to pressure-shape the spokes placed inside the lower die 305. When the first toothed plate 303 moves into the protective cover 101, the second toothed plate 304 moves in a relative direction to the first toothed plate 303. At this time, the second toothed plate 304 moves away from the upper die 204. By feeding material into the lower die 305 provided on the surface of the second toothed plate 304, when the lower die 305 on the surface of the first toothed plate 303 has finished shaping and moves away from the second toothed plate 304, the lower die 305 placed on the surface of the second toothed plate 304 moves to below the upper die 204 for automatic shaping, thereby improving the shaping efficiency of the spokes.

[0049] When the clamping plate 404 clamps and limits the side wall of the lower mold 305, the output shaft of the second motor 407 is controlled to drive the main gear 408 to rotate coaxially. When the main gear 408 rotates, it drives the auxiliary gear 409 to mesh and rotate. When the auxiliary gear 409 rotates, it drives the second lead screw 410 to rotate coaxially. The movable plate 411 on the surface of the second lead screw 410 moves relative to it. Since the end of the movable plate 411 is provided with a toothed plate 412, when the toothed plate 412 moves to the end of the toothed 405, the second motor 407 is controlled to stop rotating. At this time, the toothed plate 412 limits and fixes the toothed 405, thereby ensuring that the spokes placed inside the lower mold 305 remain stable when subjected to force, thus ensuring the shaping effect of the spokes.

[0050] During spoke trimming, cylinder 203 drives upper die 204 to move downwards vertically. Guide rods 205 on both sides of upper die 204 slide on the inner wall of guide groove. When guide rods 205 pass through guide groove, they press against pressure plate 506. Pressure plate 506 drives rack 505 to slide on one side of fixed gear 504. When rack 505 moves, it drives fixed gear 504 to mesh and rotate. Fixed gear 504 drives rotating rod 501 to rotate to 90° and stop rotating. At this time, eccentric wheel 502 on the surface of rotating rod 501 is horizontal with support plate 307. When spoke trimming is completed, the cylinder 203 drives upper die 204 to move downwards vertically. When upper die 204 is moved downwards vertically, ... Cylinder 203 drives the upper mold 204 to move vertically upward. At this time, the external force on the torsion spring 503 gradually disappears. The rotating rod 501 is driven by the force of the torsion spring 503 to rotate the eccentric wheel 502 coaxially. When the eccentric wheel 502 rotates, it supports the bottom of the support plate 307 until the eccentric end of the eccentric wheel 502 rotates to 90° and is perpendicular to the bottom of the support plate 307. At this time, the shaped wheel spokes follow the rotation of the eccentric wheel 502 and move vertically upward along the inner wall of the lower mold 305, so that the wheel moves to the outside of the lower mold 305, which facilitates the quick cutting of the shaped wheel spokes.
