Description

Technical Field

[0001] The present invention relates to a tire tread cutting device and method, and in particular to a solid tire tread cutting production device and method. Background Art

[0002] Solid tires are widely used in industrial vehicles, logistics equipment, and special machinery due to their airless, high-load-bearing, and wear-resistant properties. However, their manufacturing process is complex, especially in the tread processing, which presents significant technical challenges:

[0003] The first is the limitation of material properties. Solid tires are mostly made of high-density rubber or polyurethane composite materials with high hardness and large elastic modulus. Traditional mechanical tools are prone to generate intense frictional heat when cutting, which can cause carbonization of the material surface or damage to the internal structure, affecting the service life of the tire.

[0004] Secondly, clamping is difficult. Solid tire carcasses are highly rigid and heavy, and the uneven distribution of clamping force in traditional clamps can easily lead to cutting vibration or tire displacement, affecting processing consistency. The complex structure of the clamping device makes it difficult to achieve both rigid support and rapid access, affecting production efficiency.

[0005] Finally, there is the problem of thermal management. Although laser cutting can improve precision, the continuous action of the high-energy laser beam can easily cause the heat-affected zone (HAZ) to expand, leading to damage to the rubber vulcanization layer or delamination of the tire body. An additional cooling system is required, but the existing technology lacks coordination between cooling and cutting actions, which can easily cause cooling lag or waste of resources.

[0006] While existing technologies have attempted to address these issues through multi-axis CNC or water-cooled laser cutting, they still suffer from drawbacks such as high equipment costs, high energy consumption, and insufficient flexibility. Therefore, an integrated solution is urgently needed to overcome the bottleneck in solid tire tread processing. Summary of the Invention

[0007] In order to solve the deficiencies of the above technologies, the present invention provides a solid tire tread cutting production device and method.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is: a solid tire tread cutting production device, comprising:

[0009] The rotating table assembly is supported by a frame and connected to a stepper motor with a reducer. The upward rotating drive shaft formed by the stepper motor passes through a bearing embedded in the upper end surface of the frame.

[0010] The table clamping assembly is coaxially connected to the rotating drive shaft downward through the central column of the lower mounting plate, and a plurality of diffusion steel bars that diffuse outward from the lower mounting plate are connected along the circumferential side wall of the central column. The upper mounting plate is connected upward through a plurality of vertical plates evenly spaced in the circumference on the disk surface of the lower mounting plate. A plurality of clamping claws are hinged at even intervals on the circumferential side wall of the upper mounting plate, and each clamping claw extends upward and outward to form a clamping end. The lower end of the clamping claw extends inward and is hinged with a connecting rod, which extends upward from the interval between two adjacent vertical plates and out of the through groove of the upper mounting plate, and is hinged together on the circumferential side wall of the same transmission plate. The center of the transmission plate is downwardly connected to a cylinder piston movably penetrated through the upper mounting plate, and a cylinder body driving the cylinder piston is fixedly arranged between the upper mounting plate and the lower mounting plate;

[0011] The laser cutting assembly positions the laser head along the X-axis and Y-axis respectively through mounting rods connected to the frame.

[0012] Furthermore, multiple diffusion steel bars are simultaneously connected to the bottom surface of the lower mounting plate through its side walls, and extend outward from the lower mounting plate at equal distances. The outer ring of the lower mounting plate matches the inner ring of the solid tire, and the parts of the diffusion steel bars extending out of the lower mounting plate jointly form an annular hollow support surface for supporting the solid tire, and the annular hollow support surface is higher than the upper end surface of the frame.

[0013] Furthermore, every two diffusion steel bars correspond to a clamping claw located at the upper position, and when each clamping claw is pressed down, it forms an isosceles triangle clamping point with the two diffusion steel bars on a part of the solid tire.

[0014] Furthermore, it also includes:

[0015] A synchronous telescopic cooling component is installed with an elevated sleeve on the disk surface of the upper mounting plate. The position of the central sleeve of the elevated sleeve is higher than the transmission plate. The center of the transmission plate is fixedly connected upward with a transmission rod, and the transmission rod is slidably sleeved in the central sleeve. The upper end of the central sleeve is connected to a support block arranged laterally. The transmission rod is driven by a gear rack unit to drive a transmission shaft arranged to rotate laterally. The screw nut unit on the support block is coaxially connected to the transmission shaft, and is connected to a pull rod arranged to slide laterally in the support block through the screw nut unit. A scissor frame with multiple nitrogen nozzles is telescopically connected between the pull rod and the support block.

[0016] Furthermore, the elevated shield has legs inserted between two adjacent through slots on the upper mounting plate, and each leg is connected to the central sleeve of the elevated shield via a crossbeam.

[0017] Furthermore, the rack and pinion unit includes a rack integrally provided on the transmission rod, and a gear connected to the transmission shaft and meshing with the rack.

[0018] Furthermore, the screw nut unit includes a screw that is rotatably arranged on the upper end surface of the support block through a bearing support. The screw is coaxially connected to the transmission shaft. A nut is matched with the screw, and the lower end of the nut is connected to a slider in the support block.

[0019] Furthermore, a T-shaped slide is provided in the support block, the pull-out rod has two slides, and the slides of the pull-out rod are respectively connected to the two ends of the T-shaped slide, the slider matches the shape setting of the T-shaped slide, and the two ends of the slider are correspondingly connected to the pull-out rod.

[0020] The working method of the solid tire tread cutting production device is characterized in that the working method includes:

[0021] Solid tire positioning method based on a rotating table assembly, a table clamping assembly and a laser cutting assembly;

[0022] Also, a solid tire cooling method using a synchronous telescopic cooling component based on a solid tire positioning method.

[0023] Furthermore, the solid tire positioning method is specifically as follows: a cylinder piston drives a transmission plate to link the clamping jaws, so that each clamping jaw presses down and forms a diffused steel bar on a ring-shaped hollow support surface to clamp and position the solid tire; a stepper motor based on a rotary table assembly drives a rotating drive shaft to synchronously drive the solid tire to move; a laser cutting assembly performs laser cutting along the X / Y axis to achieve the cutting process of the tire tread during positioning or displacement;

[0024] The solid tire cooling method is specifically as follows: while the table clamping assembly clamps and positions the solid tire, the gear rack unit and the screw nut unit of the telescopic cooling assembly are synchronously driven through the transmission plate, and then the pull rod is driven to drive the scissors frame to extend, so that the nitrogen nozzle is synchronously extended out of the vertical coverage space when the clamping jaws are open, and the nitrogen nozzle is controlled to open and spray cooling gas to the tire body, and synchronous cooling is achieved in combination with laser cutting; while the table clamping assembly releases the solid tire, the gear rack unit and the screw nut unit of the telescopic cooling assembly are synchronously driven through the transmission plate, and then the pull rod is driven to drive the scissors frame to retract, and the nitrogen nozzle is controlled to close the spraying of cooling gas, so that the nitrogen nozzle is synchronously retracted into the vertical coverage space when the clamping jaws are contracted, so as not to affect the vertical lifting and placement of the solid tire.

[0025] The present invention discloses a solid tire tread cutting production device and method, offering an integrated solution combining innovative clamping, cutting path planning, and intelligent thermal management. Through the coordinated design of the clamping jaws and diffusion steel bars, each two diffusion steel bars correspond to one clamping jaw, forming an isosceles triangle of clamping points. This evenly distributes the clamping force to a localized area of ​​the tire, avoiding stress concentration and ensuring that the tire does not shift or vibrate during rotation or cutting, significantly improving processing stability. The diffusion steel bars extend outward to form an annular hollow support surface, which not only provides rigid support for the tire but also optimizes heat dissipation and chip removal efficiency through the hollow structure, while also reducing equipment weight and rotational inertia. The opening and closing of the clamping jaws is driven by a pneumatic cylinder and linked to the expansion and contraction of the cooling assembly, achieving intelligent "clamping for cooling, release for retraction" operation, avoiding cooling lag or resource waste. The clamping action of the clamping jaws is converted into the synchronous expansion and contraction of the nitrogen nozzle via a gear rack and screw nut. During clamping, the nozzle automatically extends to precisely cover the cutting area and suppress the expansion of the heat-affected zone; upon release, the nozzle automatically retracts to avoid interfering with tire handling.

DETAILED DESCRIPTION

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Embodiment 1;

[0038] A solid tire tread cutting production device includes a rotating table assembly, a table clamping assembly, and a laser cutting assembly;

[0039] Specifically, if Figure 1 The illustrated rotary table assembly includes a frame 100 having a frame structure that provides a cutting positioning reference. A stepper motor 102 connected to a reducer 101 is supported within the frame 100. A rotating drive shaft 103 extending upward from the stepper motor 102 passes through a bearing 104 embedded in the upper end surface of the frame 100, achieving low speed and high torque to drive the rotating drive shaft 103 to rotate and displace at a preset angle or speed.

[0040] like Figure 2 and Figure 3The table clamping assembly shown is coaxially connected to the rotating drive shaft 103 downward through the central column 201 of the lower mounting plate 200. The coaxial rigid connection realizes seamless transmission between the rotating table assembly and the clamping assembly. Ten diffusion steel bars 202 that diffuse outward from the lower mounting plate 200 are connected along the circumferential side wall of the central column 201. The ten diffusion steel bars 202 are simultaneously connected to the bottom surface of the lower mounting plate 200 through their side walls and extend outward from the lower mounting plate 200 at equal distances. The outer ring of the lower mounting plate 200 matches the inner ring of the solid tire. The portion of the diffusion steel bars 202 extending out of the lower mounting plate 200 together forms a ring that supports the solid tire. The hollow support surface is annular and is higher than the upper end surface of the frame 100, providing a cushion for the solid tire. Compared to a flat support surface, the hollow support surface can reduce weight and rotational inertia. It also provides operating space for a robotic arm or lifting equipment to facilitate vertical tire placement and access without interference. At the same time, the hollow structure promotes air circulation in the synchronous telescopic cooling component and chip removal in the laser cutting component, assisting in heat dissipation in the laser cutting area and allowing debris to fall naturally through the hollow gaps. Therefore, this design not only solves the requirements of placement, rotation support, and foundation elevation, but also optimizes heat dissipation and chip removal through its multifunctional design, making it a key structure that balances functionality and engineering practicality.

[0041] like Figure 3 and Figure 5As shown, the disk surface of the lower mounting plate 200 of the table clamping assembly is connected to the upper mounting plate 204 through five vertical plates 203 evenly spaced in the circumference. Five clamping claws 205 are evenly spaced and hinged on the circumferential side walls of the upper mounting plate 204. Each clamping claw 205 extends upward and outward to form a clamping end. The lower end of the clamping claw 205 extends inward and is hinged with a connecting rod 206. The connecting rod 206 extends upward from the space between two adjacent vertical plates 203 and is inserted from the through groove of the upper mounting plate 204, and is hinged together on the circumferential side wall of the same transmission plate 207. The center of the transmission plate 207 is downwardly connected to a cylinder piston 208 that is movably penetrated by the upper mounting plate 204. The cylinder body 209 that drives the cylinder piston 208 is fixedly set between the upper mounting plate 204 and the lower mounting plate 200. In this embodiment, the cylinder body 209 is fixedly connected to the upper mounting plate 204; The synchronous opening and closing of the clamping jaws is achieved in part by a linkage mechanism driven by a cylinder. The cylinder piston 208 moves up and down in the cylinder body 209, and its extension direction is rigidly connected to the center of the transmission plate 207. When the cylinder piston 208 moves upward, the transmission plate 207 moves upward accordingly; conversely, when the piston pushes down, the transmission plate moves downward, and the circumferential side walls of the transmission plate 207 are evenly hinged to five connecting rods 206, each connecting rod corresponding to a clamping jaw 205. When the cylinder piston 208 pushes the transmission plate 207 upward during the downward pressure of the clamping jaws, the connecting rod 206 is pushed upward, and the clamping jaws 205 open outward around the hinge point with the upper mounting plate 204, and the clamping end presses the solid tire; when the clamping jaws are released, when the cylinder piston 208 pushes the transmission plate 207 downward, the connecting rod 206 is subjected to a downward tension, forcing the clamping jaws 205 to close inward around the hinge point of the upper mounting plate 204, and the clamping end retracts upward to release the solid tire;

[0042] In particular, such as Figure 4 As shown, every two diffusion steel bars 202 correspond to a clamping jaw 205 located in the upper position. When each clamping jaw 205 is pressed downward, it forms an isosceles triangle clamping point with the two diffusion steel bars 202 on a portion of the solid tire. The isosceles triangle clamping point decomposes the vertical clamping force of the clamping jaw into two symmetrical radial force components, which form a combined force with the supporting force of the diffusion steel bars, forming a stable three-point force structure, effectively preventing the tire from slipping or warping during rotation or cutting. The layout of a single clamping jaw linked to two diffusion steel bars reduces the number of clamping jaws. For example, in this embodiment, five clamping jaws correspond to ten diffusion steel bars, which reduces material usage and manufacturing costs while ensuring clamping strength.

[0043] like Figure 3 As shown, the laser cutting assembly positions the laser head 301 along the X-axis and Y-axis directions respectively through the mounting rod 300 connected to the frame 100. In other embodiments, the laser cutting assembly can use an independently set robot arm to control the laser head for cutting.

[0044] Embodiment 2:

[0045] On the basis of the first embodiment, this example further includes a synchronous telescopic cooling component;

[0046] like Figure 6 As shown, the synchronous telescopic cooling component includes an elevated jacket 400 erected on the disk surface of the upper mounting plate 204, the elevated jacket 400 has legs 408 inserted between two adjacent through slots on the upper mounting plate 204, and each leg 408 is connected to the central sleeve 402 of the elevated jacket 400 through a crossbeam 409; the central sleeve 402 of the elevated jacket 400 is located higher than the transmission plate 207, and the center of the transmission plate 207 is fixedly connected upward with a transmission rod 401, which is slidably sleeved in the central sleeve 402, and the upper end of the central sleeve 402 is connected to a support block 403 arranged in the transverse direction, and the transmission rod 401 in the cavity of the support block 403 drives a transmission shaft 404 arranged to rotate in the transverse direction through a gear rack unit. Specifically, as shown Figure 8 As shown, the rack and pinion unit includes a rack 410 integrally provided on the transmission rod 401, and a gear 411 connected to the transmission shaft 404 and meshing with the rack 410. The screw nut unit on the support block 403 is coaxially connected to the transmission shaft 404, as shown in FIG. Figure 9 The screw-nut unit shown includes a screw 413 that is rotatably arranged on the upper end surface of the support block 403 through a bearing support 412. The screw 413 is coaxially connected to the transmission shaft. A nut 414 is matched with the screw 413. The lower end of the nut 414 is connected to a slider 415 in the support block 403. A T-shaped slide 416 is provided in the support block 403. The pull rod 405 has two slides, and the slides of the pull rod 405 are connected to the two ends of the T-shaped slide 416. The slider 415 matches the shape of the T-shaped slide 416. The two ends of the slider 415 are correspondingly connected to the pull rod 405. And the connection is transmitted through the screw-nut unit as shown in FIG. Figure 7 A pulling rod 405 is arranged to slide laterally inside the support block 403 shown in the figure, and a scissor frame 407 with multiple nitrogen nozzles 406 is telescopically connected between the pulling rod 405 and the support block 403. The nitrogen nozzles 406 are connected to the nitrogen generator through an elastic hose. However, it is of course not limited to the use of nitrogen for cooling. In other embodiments, air or argon is used. At the same time, it should be noted that in order to avoid interference with the power supply wiring of the elastic hose and the cylinder when the table clamping assembly rotates, and at the same time not affecting the vertical lifting and placement of the solid tire, the wiring of the elastic hose and the cylinder is hidden in the interior or side of the frame 100 or the lower mounting plate 200, and multiple turns of rotation margin are reserved, but not limited to the above method. Guide grooves or sheaths can also be provided around the rotating parts to fix the wiring in the guide groove to prevent the wiring from deviating or entangled during rotation.

[0047] The synchronous telescopic cooling component can work in conjunction with the table clamping component. The core mechanism is to convert the clamping action of the clamping claw into the synchronous telescopic of the nitrogen nozzle through mechanical linkage, so as to achieve precise coordination of cutting and cooling. When the cylinder piston 208 of the table clamping component drives the transmission plate 207 to move up and down, the transmission rod 401 in the center of the transmission plate rises and falls synchronously; the rack 410 on the transmission rod 401 engages with the gear 411 of the transmission shaft 404, converting the vertical linear motion of the transmission rod into the horizontal rotation motion of the transmission shaft 404; The movable shaft 404 rotates through the coaxially connected screw rod 413, driving the nut 414 to move laterally along the screw rod 413; the slider 415 at the bottom of the nut 414 is embedded in the T-shaped slide 416 of the support block 403, forcing the slider 415 to slide laterally along the slide. The lateral movement of the slider 415 drives the pull rods 405 on both sides to slide synchronously through the T-shaped slide 416. The lateral movement of the pull rod 405 is converted into a vertical telescopic movement through the hinged structure of the scissor frame 407, driving the multiple nitrogen nozzles 406 to extend or retract.

[0048] During the cooling synchronous control process, when the clamping jaws 205 press down to clamp the tire, the transmission plate 207 moves up, and the transmission rod 401 drives the gear rack unit and the screw nut unit to link, the pulling rod 405 pulls the shear fork frame 407 outward, and the nitrogen nozzle 406 emits cooling gas from above to suppress the heat generated by laser cutting. It should be understood that in this example, there is a group of nitrogen nozzles 406, and multiple groups of nitrogen nozzles 406 can also be synchronously driven by the transmission rod 401 through the above-mentioned disclosed structure to further improve the cooling efficiency. The focus is on the cooling synchronous control process; when the clamping jaws 205 open to release the tire, the transmission plate 207 moves down, the transmission rod 401 moves in the opposite direction, the pulling rod 405 pushes the shear fork frame 407 back, and the nitrogen nozzle 406 shrinks to avoid interfering with the tire picking and placing. The key advantage of this design is that through the multi-stage transmission of gear racks, screw nuts and scissor frames, the synchronous telescopic cooling component directly converts the mechanical energy of the clamping action into the precise extension and retraction of the nozzle, realizing the intelligent coordination of "clamping is cooling, releasing is retracting", and significantly improving the cutting efficiency and quality.

[0049] Therefore, the present invention also discloses a working method of a solid tire tread cutting production device, which comprises:

[0050] A solid tire positioning method based on a rotating table assembly, a table clamping assembly, and a laser cutting assembly; and a solid tire cooling method using a synchronous telescopic cooling assembly under the solid tire positioning method.

[0051] The solid tire positioning method is specifically as follows: the cylinder piston drives the transmission plate to link the clamping jaws, so that each clamping jaw presses down and forms a diffused steel bar with an annular hollow support surface to clamp and position the solid tire; the stepper motor based on the rotary table assembly drives the rotating drive shaft to synchronously drive the solid tire to move; the laser cutting assembly performs laser cutting along the X / Y axis to achieve the cutting process of the tire tread during positioning or displacement;

[0052] The solid tire cooling method is specifically as follows: while the table clamping assembly clamps and positions the solid tire, the gear rack unit and the screw nut unit of the telescopic cooling assembly are synchronously driven through the transmission plate, and then the pull rod is driven to drive the scissors frame to extend, so that the nitrogen nozzle is synchronously extended out of the vertical coverage space when the clamping jaws are open, and the nitrogen nozzle is controlled to open and spray cooling gas to the tire body, and synchronous cooling is achieved in combination with laser cutting; while the table clamping assembly releases the solid tire, the gear rack unit and the screw nut unit of the telescopic cooling assembly are synchronously driven through the transmission plate, and then the pull rod is driven to drive the scissors frame to retract, and the nitrogen nozzle is controlled to close the spraying of cooling gas, so that the nitrogen nozzle is synchronously retracted into the vertical coverage space when the clamping jaws are contracted, so as not to affect the vertical lifting and placement of the solid tire.

[0053] The core advantage of this working method is that the cylinder drives the clamping jaws and the diffusion steel bars to form an isosceles triangle clamping point, ensuring the rigid fixation and uniform stress of the tire; the stepper motor drives the synchronous displacement of the rotary table, combined with the X / Y-axis laser head to dynamically adjust the cutting path, to achieve millimeter-level precision cutting and efficient processing of complex tread patterns; the synchronous telescopic cooling component automatically extends the nitrogen nozzle with the clamping action to suppress the expansion of the laser heat-affected zone and avoid tire damage; the annular hollow support surface optimizes heat dissipation and chip removal, reducing energy consumption and maintenance costs; the full-process automated linkage (clamping-rotation-cutting-cooling) significantly improves processing efficiency and finished product qualification rate, taking into account high precision, high stability and economy, and is suitable for the customized intelligent manufacturing needs of special tires.

[0054] The above embodiments are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also fall within the scope of protection of the present invention.
