Description

Technical Field

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

[0002] Due to their characteristics of being non-pneumatic, high-load-bearing, and wear-resistant, solid tires are widely used in industrial vehicles, logistics equipment, and special machinery. However, their manufacturing process is complex, and there are significant technical challenges, especially in the tread processing section:

[0003] Firstly, material property limitations. Solid tires mostly use high-density rubber or polyurethane composite materials, which have high hardness and large elastic modulus. When cutting with traditional mechanical tools, intense frictional heat is easily generated, resulting in surface carbonization of the material or damage to the internal structure, affecting the service life of the tire.

[0004] Secondly, it is difficult to clamp. The solid tire carcass has high rigidity and large weight. The uneven distribution of the clamping force of traditional fixtures easily leads to cutting vibration or tire displacement, affecting the processing consistency. The clamping device has a complex structure and it is difficult to balance the requirements of rigid support and rapid picking and placing, affecting the production efficiency.

[0005] Finally, it is a thermal management problem. Although laser cutting can improve the accuracy, the continuous action of the high-energy laser beam easily causes the expansion of the heat-affected zone (HAZ), resulting in the damage of the rubber vulcanized layer or the delamination of the tire carcass. An additional cooling system is required, but in the existing technology, the coordination between the cooling and cutting actions is insufficient, easily causing cooling lag or resource waste.

[0006] In the existing technology, although attempts have been made to improve the above problems through multi-axis numerical control or water-cooled laser cutting, there are still defects such as high equipment cost, high energy consumption, and insufficient flexibility. Therefore, an integrated solution is urgently needed to break through the bottleneck of 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] A rotary table assembly, which is supported and connected by a frame to a stepping motor with a built-in reducer, and the rotary drive shaft formed upward by the stepping motor passes through a bearing embedded in the upper end face of the frame;

[0010] The tabletop clamping assembly coaxially connects a rotary drive shaft downward through the central column of the lower mounting plate, and connects a plurality of diffusion steel bars that laterally extend outward from the lower mounting plate along the circumferential side wall of the central column. The upper mounting plate is connected upward to the upper mounting plate through a plurality of upright plates that are evenly spaced circumferentially on the disk surface of the lower mounting plate. A plurality of clamping jaws are evenly spaced and hinged on the circumferential side wall of the upper mounting plate. Each clamping jaw extends upward and outward to form a clamping end. The lower end of the clamping jaw extends inward and is hinged with a connecting rod. The connecting rod penetrates upward from the slot of the upper mounting plate through the space between two adjacent upright plates and is commonly hinged on the circumferential side wall of the same transmission plate. The center of the transmission plate is connected downward to a cylinder piston that movably penetrates through the upper mounting plate. The cylinder block that drives and connects the cylinder piston is fixedly arranged between the upper mounting plate and the lower mounting plate;

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

[0012] Further, a plurality of diffusion steel bars are simultaneously connected to the bottom surface of the lower mounting plate through their side walls and extend outward from the lower mounting plate at equal intervals. The outer ring of the lower mounting plate matches the inner ring of a solid tire. The parts of the diffusion steel bars that extend out of the lower mounting plate together 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] Further, every two diffusion steel bars correspond to a clamping jaw located in the upper position. When each clamping jaw presses down, it forms an isosceles triangle clamping point with the two diffusion steel bars on the solid tire.

[0014] Further, it further includes:

[0015] The synchronous telescopic cooling assembly erects a high-altitude sheath upward on the disk surface of the upper mounting plate. The position of the central sleeve of the high-altitude sheath is higher than that of the transmission plate. The center of the transmission plate is fixedly connected upward with a transmission rod. The transmission rod is slidably sleeved in the central sleeve. The upper end of the central sleeve is connected with a support block arranged transversely. The transmission rod drives a transmission shaft that rotates transversely through a gear and rack unit. The lead screw nut unit on the support block is coaxially connected with the transmission shaft and drives a pull rod that slides transversely in the support block through the lead screw nut unit. The pull rod is telescopically connected with a shear fork frame having a plurality of nitrogen nozzles between the pull rod and the support block.

[0016] Further, the high-altitude sheath has legs that are inserted between two adjacent slots on the upper mounting plate, and each leg is connected to the central sleeve of the high-altitude sheath through a cross beam.

[0017] Further, the gear and rack unit includes a rack integrally arranged 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 on the screw, and a slider is connected to the lower end of the nut into the support block.

[0019] Furthermore, a T-shaped slideway is provided in the support block, the pull-out rod has two slideways, and the pull-out rod slideways are respectively connected to the two ends of the T-shaped slideway, the slider matches the shape of the T-shaped slideway, 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 comprises:

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

[0022] And, 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: the cylinder piston drives the transmission plate to link the clamping jaws, so that each clamping jaw presses down and forms a diffusion steel bar of the annular hollow support surface to clamp and position the solid tire, and the stepper motor based on the rotating 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 direction to achieve the cutting of the tire tread in the positioning or displacement process;

[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, thereby driving the pull rod 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, thereby driving the pull rod to drive the scissors frame to retract, controlling the nitrogen nozzle to close the spray cooling gas, and synchronously retracting the nitrogen nozzle 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, which is an integrated solution integrating innovative clamping, cutting path planning and intelligent thermal management linkage. Through the linkage design of the clamping jaws and the diffusion steel bars, every two diffusion steel bars correspond to one clamping jaw, forming an isosceles triangle clamping point, evenly dispersing the clamping force to the local area of the tire, avoiding stress concentration and ensuring that the tire does not displace or vibrate during rotation or cutting, significantly improving the processing stability. The diffusion steel bars extend outwards to form an annular hollow support surface, which not only provides rigid support for the tire, but also optimizes the heat dissipation and chip removal efficiency through the hollow structure, while reducing the weight of the equipment and the rotational inertia. The opening and closing action of the clamping jaws is driven by a cylinder and linked with the telescopic action of the cooling component to realize the intelligent operation of "clamping means cooling, releasing means retracting", avoiding cooling lag or resource waste. Through the transmission of the gear rack and the screw nut, the clamping action of the clamping jaws is converted into the synchronous telescopic movement of the nitrogen nozzles. When clamping, the nozzles automatically extend and accurately cover the cutting area to inhibit the expansion of the heat affected zone; when releasing, the nozzles automatically retract to avoid interfering with the picking and placing of the tire.

Detailed implementation mode

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

[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, as Figure 1 shown, the rotating table assembly includes a frame body 100 with a frame structure to provide a cutting positioning reference. By internally supporting and connecting a stepping motor 102 with a built-in speed reducer 101 in the frame body 100, the rotary drive shaft 103 formed upward by the stepping motor 102 passes through the bearing 104 embedded in the upper end surface of the frame body 100, realizing low-speed and high-torque driving of the rotary drive shaft 103 to rotate and displace at a preset angle or speed;

[0040] As Figure 2 and Figure 3The shown tabletop clamping assembly is coaxially connected to the rotary drive shaft 103 downward through the central column 201 of the lower mounting plate 200. The coaxial rigid connection realizes the seamless transmission between the rotary table assembly and the clamping assembly. Ten diffusion steel bars 202 that laterally diffuse out of 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 parts of the diffusion steel bars 202 that extend out of the lower mounting plate 200 together form an annular hollow support surface for supporting the solid tire. The annular hollow support surface is higher than the upper end surface of the frame 100 to raise the solid tire; compared with the flat support surface, the annular hollow support surface can reduce the weight and rotational inertia; it provides an operating space for the robotic arm or hoisting equipment to facilitate the vertical picking and placing of the tire and avoid interference; at the same time, the hollow structure promotes the air circulation of the synchronous telescopic cooling assembly and the chip removal of the laser cutting assembly, assisting in the heat dissipation of the laser cutting area and the natural dropping of debris through the hollow gaps; therefore, this design not only solves the basic requirements of picking and placing, supporting rotation, and raising the height, but also optimizes heat dissipation and chip removal through the multi-functional design, which is the key structure that takes into account both functionality and engineering practicality;

[0041] As Figure 3 and Figure 5As shown, the disk surface of the lower mounting disk 200 of the table clamping assembly is upwardly connected to the upper mounting disk 204 through five vertically arranged plates 203 that are evenly spaced circumferentially. Five clamping jaws 205 are evenly spaced and hinged on the circumferential side wall of the upper mounting disk 204. Each clamping jaw 205 extends upward and outward to form a clamping end. The lower end of the clamping jaw 205 extends inward and is hinged with a connecting rod 206. The connecting rod 206 penetrates upward through the slot of the upper mounting disk 204 from the space between two adjacent vertically arranged plates 203, and is commonly hinged 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 movably penetrates through the upper mounting disk 204. The cylinder block 209 that drives and connects the cylinder piston 208 is fixedly arranged between the upper mounting disk 204 and the lower mounting disk 200. In this embodiment, the cylinder block 209 is fixedly connected to the upper mounting disk 204; this part realizes the synchronous opening and closing of the clamping jaws through a linkage mechanism driven by a cylinder. The cylinder piston 208 moves up and down in the cylinder block 209, and its telescopic 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 is pushed downward, the transmission plate moves downward. Five connecting rods 206 are evenly hinged on the circumferential side wall of the transmission plate 207, and each connecting rod corresponds to a clamping jaw 205. When the clamping jaw is pressed down and the cylinder piston 208 pushes the transmission plate 207 upward, the connecting rod 206 is pushed upward, and the clamping jaw 205 opens outward around the hinge point with the upper mounting disk 204, and the clamping end presses the solid tire tightly; during the release process of the clamping jaw, when the cylinder piston 208 pushes the transmission plate 207 downward, the connecting rod 206 is subjected to a downward pulling force, forcing the clamping jaw 205 to close inward around the hinge point of the upper mounting disk 204, and the clamping end moves upward to release the solid tire;

[0042] Specifically, as Figure 4 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 down, it forms an isosceles triangle clamping point with the two diffusion steel bars 202 on the local part of the solid tire. The isosceles triangle clamping point decomposes the vertical clamping force of the clamping jaw into two symmetrical radial component forces, which form a resultant force with the supporting force of the diffusion steel bars, forming a stable three-point stress structure, effectively preventing the tire from slipping or warping during rotation or cutting. The layout of a single clamping jaw linking two diffusion steel bars reduces the number of clamping jaws. For example, in this embodiment, five clamping jaws correspond to ten diffusion steel bars, reducing the material usage and manufacturing cost while ensuring the clamping strength.

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

[0044] Embodiment Two;

[0045] Based on the first embodiment, this example further includes a synchronous telescopic cooling component;

[0046] As Figure 6 shown, the synchronous telescopic cooling component includes an elevated sheath 400 erected upward on the disk surface of the upper mounting disk 204. The elevated sheath 400 has legs 408 inserted between two adjacent through slots on the upper mounting disk 204, and each leg 408 is connected to the central sleeve 402 of the elevated sheath 400 through a cross beam 409; the position of the central sleeve 402 of the elevated sheath 400 is higher than that of the transmission plate 207. A transmission rod 401 is fixedly connected upward at the center of the transmission plate 207. The transmission rod 401 is slidably sleeved in the central sleeve 402. The upper end of the central sleeve 402 is connected with a support block 403 arranged horizontally. In the cavity of the support block 403, the transmission rod 401 drives a transmission shaft 404 rotatably arranged horizontally through a gear and rack unit. Specifically, as Figure 8 shown, the gear and rack unit includes a rack 410 integrally arranged 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 Figure 9 shown, the screw nut unit includes a screw rod 413 rotatably arranged on the upper end surface of the support block 403 through a bearing support 412. The screw rod 413 is coaxially connected with the transmission shaft. A nut 414 is arranged in a matching manner on the screw rod 413. The lower end of the nut 414 is connected with a slider 415 inside the support block 403. A T-shaped slideway 416 is formed inside the support block 403. There are two pull rods 405, and the slideways of the pull rods 405 are respectively communicated with the two ends of the T-shaped slideway 416. The slider 415 is arranged in a shape matching the T-shaped slideway 416, and the two ends of the slider 415 are correspondingly connected to the pull rods 405. And through the transmission connection of the screw nut unit, as Figure 7 shown, the pull rods 405 slidably arranged horizontally inside the support block 403. The pull rods 405 and the support block 403 are telescopically connected with a scissor frame 407 having a plurality of nitrogen nozzles 406. The nitrogen nozzles 406 are communicated with a nitrogen generating device through an elastic hose. However, of course, it is not limited to using 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 to the power supply wiring of the elastic hose and the cylinder when the table clamping component rotates, and at the same time not affect the vertical lifting and placing of the solid tire, the wiring of the elastic hose and the cylinder is hidden inside or on the side of the frame 100 or the lower mounting disk 200, and a multi-turn rotation allowance is reserved. However, it is 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 grooves to avoid the wiring deviating or winding during the rotation process.

[0047] The synchronous telescopic cooling component can work in coordination 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 meshes 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, and 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 telescopic movement in the vertical direction 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 are pressed down to clamp the tire, the transmission plate 207 moves up, the transmission rod 401 drives the gear rack unit and the screw nut unit to work in conjunction, the pulling rod 405 pulls the scissor 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, a group of nitrogen nozzles 406 are provided, and multiple groups of nitrogen nozzles 406 can also be synchronously driven by the transmission rod 401 through the above-disclosed structure to further improve the cooling efficiency. The focus is on the cooling synchronous control process; when the clamping jaws 205 are opened 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 scissor frame 407 inward and retracts, and the nitrogen nozzle 406 shrinks to avoid interfering with the tire removal. 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 precise telescopic and retracting 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, the working method comprising:

[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] Among them, the specific method for positioning the solid tire is as follows: The cylinder piston drives the drive plate to link the jaws, so that each jaw presses down on the solid tire for clamping and positioning with the diffusion steel bars forming an annular hollow support surface. The stepping motor of the rotary table assembly drives the rotary drive shaft to synchronously drive the solid tire to displace; The laser cutting assembly performs laser cutting along the X / Y axis directions to achieve the cutting of the tire tread during the positioning or displacement process.

[0052] The specific method for cooling the solid tire is as follows: While the table clamping assembly clamps and positions the solid tire, the gear rack unit and the ball screw nut unit of the telescopic cooling assembly are synchronously driven through the drive plate, and then the pull rod is driven to drive the scissors frame to extend, so that the nitrogen nozzles synchronously extend beyond the vertical coverage space when the jaws are in the open state. The nitrogen nozzles are controlled to open and spray cooling gas to the tire carcass, 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 ball screw nut unit of the telescopic cooling assembly are also synchronously driven through the drive plate, and then the pull rod is driven to drive the scissors frame to retract, and the nitrogen nozzles are controlled to close and stop spraying the cooling gas, so that the nitrogen nozzles synchronously retract into the vertical coverage space when the jaws are in the contracted state, so as not to affect the vertical lifting and placing of the solid tire.

[0053] The core advantages of this working method are as follows: The cylinder drives the jaws and the diffusion steel bars to form an isosceles triangle clamping point, ensuring rigid fixation and uniform stress of the tire; The stepping motor drives the rotary table to displace synchronously, and in combination with the dynamic adjustment of the cutting path by the X / Y axis laser head, millimeter-level precision cutting and efficient processing of complex tread patterns are achieved; The telescopic cooling assembly automatically extends the nitrogen nozzles along with the clamping action, suppressing the expansion of the laser heat affected zone and avoiding damage to the tire carcass; The annular hollow support surface optimizes heat dissipation and chip removal, reducing energy consumption and maintenance costs; The full-process automatic linkage (clamping - rotation - cutting - cooling) significantly improves the processing efficiency and the qualified rate of finished products, taking into account high precision, high stability and economy, and is applicable to the customized manufacturing requirements of special tires.

[0054] The above embodiments are not limitations to the present invention, and the present invention is not limited to the above examples either. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present invention also fall within the protection scope of the present invention.
