Description

Technical Field

[0001] The present invention relates to the technical field of tire three-dimensional molding, and particularly to a tire molding device and a rapid manufacturing method. Background Art

[0002] Tires are important components that come into contact with the ground for transportation vehicles. Whether it is ground transportation vehicles or air transportation vehicles, the presence of tires can be glimpsed. However, due to the complex structure of tires, the processes in the production and molding are very cumbersome. And because the existing technological processes were determined many years ago, some processes have not been synchronously upgraded and optimized with the progress of technology, resulting in difficulties in further improving production efficiency and reducing defect rates. For example, the current tire production closing process will cause the spacing of the originally laid cord to become disordered, increasing the probability of later defects. The laying of the cord fabric layer also relies on manual cutting of the cord fabric layer, and the cutting quality is unstable, affecting production efficiency. Therefore, a tire molding device and a corresponding automatic rapid manufacturing method for tires are needed to promote the progress of tire production technology. During the process of controlling the rotation of the tire inner tube, the staff needs to rely on manually touching the inner tube to rotate it, which is laborious in the operation process. Therefore, the present invention provides a tire molding device and a rapid manufacturing method. Summary of the Invention

[0012] A rapid manufacturing method for a tire forming device includes the following steps:

[0013] S1. Before producing a certain type of tire, select a suitable cord forming sleeve according to its geometric dimensions, and weave a cord structure with a three-dimensional shape on it;

[0014] S2. When producing a tire, select a suitable-sized inner core, then fill the inner core with gas to make it expand and have the shape of the internal contour of the tire, and put an unvulcanized inner liner rubber on its surface;

[0015] S3. Place the outer shell of the device body inside the inner ring of the inner core. Then, generate a sliding force by pushing the conical push block. During the sliding process of the conical push block, the sliding plate slides inside the auxiliary chute opened on the conical push block. Utilize the conical appearance of the conical push block to make the extension rod on the side of the sliding plate slide outward inside the wall groove opened on the outer shell of the device body, so that the two inner tube engaging arc-shaped blocks are engaged with the inner core. During the sliding and pushing process of the conical push block, the return spring is compressed by the fixed square plate fixedly connected to the surface of the pushing rod. At the same time, the pushing rod slides inside the extension sleeve fixedly installed on the side of the outer shell of the device body. Then, the positioning screw rod rotates in the first spiral groove opened on the extension sleeve and cooperates with the second spiral groove and the round head bump opened on the pushing rod to be tightly clamped. At the same time, after removing the positioning screw rod, under the action of the return spring, it can quickly drive the inner tube engaging arc-shaped block fixedly installed on the side of the extension rod to retract. Take one end of the thread of the wound cord from the cord forming sleeve, pass it through the tension pulley and transition to the tire three-dimensional forming device. Rotate the inner core of the tire three-dimensional forming device to wind the cord, and at the same time spray and dip the glue;

[0016] S4. Guide the strip-shaped rubber compound to the tire three-dimensional forming device, and compact it on the cord sprayed with dip glue by the rubber rolling wheel. At the same time, utilize the conical push block to assist the inner core to rotate;

[0017] S5. When the rubber compound fills the gap between the inner core and the outer shell as the inner core rotates, the spring outside the outer shell will provide a certain pressure due to being compressed. At this time, increase the temperature of the outer shell to perform the hot pressing operation of the rubber compound and the cord;

[0018] S6. After hot pressing, let it stand and cool slightly. Rotate the tire three-dimensional forming device. The hot-pressed rubber compound and cord will rotate backward. At the same time, the untreated rubber compound and cord will be conveyed to the surface of the tire three-dimensional forming device from the rubber conveying roller or the cord forming sleeve again;

[0019] S7. Repeat the above steps until the manufacture of the cord layer is completed;

[0020] S8. Extract the gas in the inner core to make it shrink. At the same time, after removing the positioning screw rod, under the action of the return spring, it can quickly drive the inner tube engaging arc-shaped block fixedly installed on the side of the extension rod to retract, and then extract it together with the inner core from the formed cord layer;

[0021] S9. Transfer the formed cord layer to perform the arrangement of the tread and sidewall rubber and the vulcanization molding of the whole tire.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The tire forming device and rapid manufacturing method. The entire device weaves cord into a three-dimensional cord fabric layer on a cord forming sleeve, which can avoid abnormal changes in cord spacing and angle during the closing and forming of the cord fabric layer in traditional processes. At the same time, it has multiple sizes, can adapt to various types of tires, is convenient for transportation, and can improve production efficiency.

[0024] 2. The tire forming device and rapid manufacturing method. The entire device can hot-press cord with a certain three-dimensional structure and rubber raw materials in a three-dimensional forming device, which can reduce the residual stress generated in traditional processes by first calendering and then forming, enhance the load-bearing capacity of the tire. At the same time, this new cord fabric layer winding method can reduce the excessive lap joints generated during the assembly of a single cord fabric layer in traditional processes, enhance the structural reliability of the tire cord fabric layer, and also facilitate the realization of automation in the production process.

[0025] 3. The tire forming device and rapid manufacturing method. Place the main body shell of the device inside the inner ring of the inner core, and then generate a sliding force through the pushing auxiliary chute. During the sliding of the conical push block, the sliding plate slides inside the auxiliary chute opened on the conical push block. Utilize the conical appearance of the conical push block to make the side extension rod of the sliding plate slide outward inside the wall groove opened on the main body shell of the device, so that the two inner tire engaging arc-shaped blocks are engaged with the inner core. During the sliding and pushing process of the conical push block, the conical push block squeezes the return spring through the fixed square plate fixedly clamped on the surface of the pushing rod fixedly connected thereto. At the same time, the pushing rod slides inside the extension housing fixedly installed on the side of the main body shell of the device, and then is tightly clamped through the cooperation of the positioning screw rod rotating in the first spiral groove opened on the extension housing, the second spiral groove opened on the pushing rod, and the round head protrusion. Thus, the auxiliary handle on the side of the conical push block is used to assist in rotating the inner core, which can achieve the effect of labor saving and controllable rotation speed. At the same time, after removing the positioning screw rod, without the thread fastening, the conical push block can quickly drive the inner tire engaging arc-shaped block fixedly installed on the side of the extension rod to retract under the action of the compression and rebound of the return spring, which is convenient for the installation and disassembly of the device, reduces the installation and disassembly time, and does not affect the deflation and folding operation of the inner core.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figures 1 - 10, a tire forming device, including a cord forming sleeve 2. After the carcass ply completes the forming operation, in a similar manner, the textile forming angle of the cord 1 on the cord forming sleeve 2 can be changed to adapt to the cord angles of different cord plies, and then the production of the belt layer and the buffer layer is carried out. The surface of the cord forming sleeve 2 is wound with the cord 1. The cord 1 is a three-dimensional structure and is wound on the cord forming sleeve 2. The surface of the cord 1 is fitted with a tensioning wheel 5. One end of the cord 1 is wound with an inner core 41. The inner core 41 rotates a certain angle, so that the cord 1 sprayed with dipping rubber and the rubber compound 3 enter the gap between the inner core 41 and the outer shell 42. At this time, the spring 43 is compressed, continuously generating pressure on the outer shell 42, so that the rubber compound 3 and the cord 1 are further compacted. The surface of the inner core 41 is provided with the rubber compound 3. On the other side of the rubber compound 3 is provided a rubber rolling wheel 31. The rubber rolling wheel 31 is located at the starting point of the outer shell 42 and is used to compact the rubber compound 3 in the gap between the inner core 41 and the outer shell 42. The surface of the rubber rolling wheel 31 is fitted with the outer shell 42. After the hot pressing operation is completed, it enters the cooling stage. Flowing cooling air is added outside the outer shell 42. The outer shell 42 contains a large number of through tiny pores, which can allow air to flow in, while the rubber will not pass through these pores. After cooling for a period of time, the rubber compound 3 detaches from the inner wall of the outer shell 42, facilitating the next operation. The surface of the outer shell 42 is fixedly connected with a spring 43. The spring 43 is evenly arranged on the outer surface of the outer shell 42 and provides a certain pressure for the outer shell 42. The side of the spring 43 is fixedly connected with a tire three-dimensional forming device 4. The tire three-dimensional forming device 4 is mainly divided into an inner core 41 and an outer shell 42, and there is a certain gap between them. The inner core 41 can rotate around a fixed axis.

[0040] Among them; inside the inner core 41 is provided with an equipment main body housing 6. Rotating the inner core 41, the formed ply will rotate backward with the inner core 41. At the same time, the untreated rubber compound 3 and the cord 1 will be respectively conveyed from the outside to the surface of the inner core 41 and cycle the previous forming operation. And after the forming and winding of the ply are completed, the gas filled in the inner core 41 is extracted, and the inner core 41 can be folded and contracted, facilitating removal. Inside the equipment main body housing 6 is provided a conical push block 10. The surface of the conical push block 10 is provided with two auxiliary sliding grooves 9. Inside both of the two auxiliary sliding grooves 9 are slidably connected with sliding plates 11. The side of the sliding plate 11 is fixedly connected with an extension rod 7. The other end of the extension rod 7 is fixedly installed with an inner tube engaging arc-shaped block 8.

[0041] Among them; the surface of the cord 1 is attached with an impregnating glue outlet device 44. When the cord 1 is sent onto the core 41 coated with uncured inner liner rubber and passes through the impregnating glue outlet device 44, the impregnating glue outlet device 44 sprays the impregnating glue, so that the cord 1 is firmly adhered to the core 41. And the impregnating glue outlet device 44 can adopt the form of combining a nozzle and a brush to evenly and completely apply the impregnating glue on the surface of the cord layer. At the same time, the impregnating glue outlet device 44 adopts the way of spraying at a short distance, that is, the impregnating glue is sprayed onto the surface of the cord layer at a high flow rate from a number of small nozzles. The side of the impregnating glue outlet device 44 is fixedly connected with a tire three-dimensional forming device 4.

[0042] Among them; the core 41 includes an air inlet 45, a flexible film 46 and a rigid shell 47. The flexible film 46 is arranged on the side of the rigid shell 47. The flexible film 46 is a connecting component of a number of dispersed rigid shells 47, and the two are firmly combined together; the air inlet 45 is used as an inflation inlet. After the core 41 is inflated, it can expand and stretch into Figure 3 the structure shown. This structure has a certain stiffness and can withstand a certain external pressure. The side of the core 41 is provided with an air inlet 45.

[0043] Among them; the side of the conical push block 10 is fixedly connected with a push rod 12. The surface of the push rod 12 is fixedly clamped with a fixed square plate 14. The side of the fixed square plate 14 is fixedly installed with a return spring 13, and the other end of the return spring 13 is fixedly connected with the conical push block 10.

[0044] Among them; wall grooves 19 are respectively opened on both sides of the equipment main body shell 6, and extension support rods 7 are slidably connected inside the wall grooves 19.

[0045] Among them; an extension sleeve 17 is fixedly installed on the side of the equipment main body shell 6. A push rod 12 is slidably connected inside the extension sleeve 17. A second spiral groove 16 is opened on the side of the push rod 12, and a first spiral groove 15 is opened on the side of the extension sleeve 17. A positioning screw rod 18 is connected and matched inside the first spiral groove 15 and the second spiral groove 16.

[0046] One end of the extension housing 17 away from the housing 6 of the device body is fixedly provided with a support base 200. One side of the support base 200 close to the center of the extension housing 17 is provided with a groove 201. A telescopic block is fixedly arranged in the groove 201. One side of the telescopic block close to the center of the extension housing 17 is fixedly provided with a plurality of round-headed bumps 900. A return spring 203 is fixedly arranged between the telescopic block and the bottom of the groove 201. Through the arrangement of the round-headed bumps, when the positioning screw rod is not pushed by an external force, the round-headed bumps can enter the spiral groove of the positioning screw rod to clamp the positioning screw rod, so as to prevent premature reset under the elastic force of the return spring 13. When an external force pushes the push rod 12 to move, and then pushes the positioning screw rod to move, the round-headed bumps will come out of the spiral groove again, thus not hindering the movement of the positioning screw rod.

[0047] A rapid manufacturing method of a tire forming device includes the following steps:

[0048] S1. Before producing a certain type of tire, select a suitable cord forming sleeve 2 according to its geometric dimensions, and weave a cord 1 structure with a three-dimensional shape on it;

[0049] S2. When producing a tire, first select a suitable size inner core 41, then fill the inner core 41 with gas to make it expand and have the shape of the inner contour of the tire, and put an unvulcanized inner liner rubber layer on its surface;

[0050] S3. Place the housing 6 of the device body inside the inner ring of the inner core 41, and then generate a sliding force by pushing the tapered push block 10. During the sliding process of the tapered push block 10, the sliding plate 11 slides inside the auxiliary chute 9 opened on the tapered push block 10. By using the tapered appearance of the tapered push block 10, the side extension strut 7 of the sliding plate 11 slides outwards inside the wall groove 19 opened on the housing 6 of the device body, so that the two inner tire engaging arc-shaped blocks 8 and 41 are engaged. During the sliding and pushing process of the tapered push block 10, the return spring 13 is squeezed by the fixed square plate 14 fixedly clamped on the surface of the push rod 12 fixedly connected thereto. At the same time, the push rod 12 slides inside the extension housing 17 fixedly installed on the side of the housing 6 of the device body, and then is tightly clamped through the cooperation of the positioning screw rod 18 rotating in the first spiral groove 15 opened on the extension housing 17, the second spiral groove 16 opened on the push rod 12 and the round-headed bumps. Take one end of the thread of the wound cord 1 from the cord forming sleeve 2, pass it through the tensioning wheel 5 and then to the tire three-dimensional forming device 4, rotate the inner core 41 of the tire three-dimensional forming device 4 to wind the cord 1, and spray and dip glue at the same time;

[0051] S4. Lead the strip-shaped rubber compound 3 to the tire three-dimensional forming device 4, and compact it on the cord 1 sprayed with dipping glue by the rubber rolling wheel 31. At the same time, use the tapered push block 10 to assist in rotating the 41;

[0052] S5. When the rubber compound 3 fills the gap between the inner core 41 and the outer shell 42 as the inner core 41 rotates, the spring 43 outside the outer shell 42 will provide a certain pressure due to being compressed. At this time, the temperature of the outer shell 42 is increased to perform the hot pressing operation on the rubber compound 3 and the cord 1.

[0053] S6. After slightly standing still and cooling after hot pressing, rotate the tire three-dimensional forming device 4. The hot-pressed rubber compound 3 and the cord 1 will rotate backward. At the same time, the untreated rubber compound 3 and the cord 1 will be conveyed from the rubber conveying roller or the cord forming sleeve 2 to the surface of the tire three-dimensional forming device 4.

[0054] S7. Repeat the above steps until the manufacture of the carcass ply is completed.

[0055] S8. Extract the gas in the inner core 41 to make it shrink. At the same time, after removing the positioning screw rod 18, under the action of the return spring 13, the inner tube engaging arc-shaped block 8 fixedly installed on the side of the extension support rod 7 can be quickly driven to retract, and then it and the inner core 41 are withdrawn from the formed carcass ply together.

[0056] S9. Transfer the formed carcass ply to perform the arrangement of the tread and sidewall rubber and the vulcanization molding of the whole tire.

[0057] Working principle: During the working process, select a suitable cord forming sleeve 2 according to the geometric dimensions of the tire, and textile a cord 1 structure with a three-dimensional shape on it. First, select a suitable-sized inner core 41, then fill the inner core 41 with gas to make it expand and have the shape of the internal contour of the tire, and put an unvulcanized inner liner rubber layer on its surface. Place the outer shell 6 of the equipment main body inside the inner ring of the inner core 41, and then generate a sliding force by pushing the auxiliary chute 9. During the sliding process of the conical push block 10, the sliding plate 11 slides inside the auxiliary chute 9 opened on the conical push block 10. Utilize the conical appearance of the conical push block 10 to make the side extension rod 7 of the sliding plate 11 slide outwards inside the wall groove 19 opened on the outer shell 6 of the equipment main body, so that the two inner tube engaging arc-shaped blocks 8 are engaged with the inner core 41. During the sliding and pushing process of the conical push block 10, the compression spring 13 is compressed by the fixed square plate 14 fixedly clamped on the surface of the pushing rod 12 fixedly connected thereto. At the same time, the pushing rod 12 slides inside the extension sleeve 17 fixedly installed on the side of the outer shell 6 of the equipment main body, and then rotates through the positioning screw rod 18 in the first spiral groove 15 opened on the extension sleeve 17 and is tightly clamped in cooperation with the second spiral groove 16 and the round head bump 900 opened on the pushing rod 12; Take one end of the thread of the coiled cord 1 from the cord forming sleeve 2, pass it through the tensioning wheel 5 and transition it to the tire three-dimensional forming device 4. Rotate the inner core 41 of the tire three-dimensional forming device 4 to wind the cord 1, and at the same time spray and dip the glue. Lead the strip-shaped rubber compound 3 to the tire three-dimensional forming device 4, and compact it on the cord 1 sprayed with the dipped glue by the rubber rolling wheel 31. At the same time, utilize the conical push block 10 to assist in rotating the inner core 41. When the rubber compound 3 fills the gap between the inner core 41 and the outer shell 42 as the inner core 41 rotates, the spring 43 outside the outer shell 42 will provide a certain pressure due to being compressed. At this time, raise the temperature of the outer shell 42 to perform the hot pressing operation of the rubber compound 3 and the cord 1. After hot pressing, let it stand and cool slightly, and rotate the tire three-dimensional forming device 4. The hot-pressed rubber compound 3 and the cord 1 will rotate backward, and at the same time, the untreated rubber compound 3 and the cord 1 will be conveyed to the surface of the tire three-dimensional forming device 4 from the rubber conveying roller or the cord forming sleeve 2. Cycle through these steps until the manufacturing of the tire cord layer is completed, then evacuate the gas in the inner core 41 to make it contract. At the same time, pull the bump and the telescopic block apart and separate from the spiral thread on the positioning screw rod 18, and then remove the positioning screw rod 18. Under the action of the compression spring 13, it can quickly drive the inner tube engaging arc-shaped block 8 fixedly installed on the side of the extension rod 7 to retract, and then extract it together with the inner core 41 from the formed cord layer. Finally, transfer the formed cord layer to perform the arrangement of the tread and sidewall rubber and the vulcanization molding of the whole tire.

8. A rapid manufacturing method of a tire forming device according to claim 7, comprising the following steps: S1. Before producing a certain type of tire, select a suitable cord forming sleeve according to its geometric dimensions, and textile a cord structure with a three-dimensional shape on it; S2. When producing a tire, first select a suitable size inner core, then fill the inner core with gas to make it expand and have the shape of the inner contour of the tire, and put an unvulcanized inner liner rubber on its surface; S3. Place the housing of the device main body inside the inner ring of the inner core, and then generate a sliding force by pushing the conical push block. During the sliding process of the conical push block, the sliding plate slides inside the auxiliary chute opened on the conical push block. Utilize the conical appearance of the conical push block to make the extension rods on the side of the sliding plate slide outwards inside the wall groove opened on the housing of the device main body, so that the two inner tire engaging arc-shaped blocks are engaged with the inner core. During the sliding and pushing process of the conical push block, the return spring is compressed by the fixed square plate fixedly clamped on the surface of the pushing rod fixedly connected thereto. At the same time, the pushing rod slides inside the extension housing fixedly installed on the side of the housing of the device main body, and then is tightly clamped through the cooperation of the positioning screw rod rotating in the first spiral groove opened on the extension housing, the second spiral groove opened on the pushing rod and the round-headed bumps; Take one end of the thread of the wound cord from the cord forming sleeve, pass it through the tension pulley and then to the tire three-dimensional forming device, rotate the inner core of the tire three-dimensional forming device to wind the cord, and spray dipping glue at the same time; S4. Lead the strip-shaped rubber compound to the tire three-dimensional forming device, and compact it on the cord sprayed with dipping glue by the rubber rolling wheel. At the same time, use the conical push block to assist in rotating the inner core; S5. When the rubber compound fills the gap between the inner core and the outer shell with the rotation of the inner core, the spring outside the outer shell will provide a certain pressure due to being compressed. At this time, increase the temperature of the outer shell and perform the hot pressing operation of the rubber compound and the cord; S6. After hot pressing, let it stand and cool slightly, rotate the tire three-dimensional forming device. The hot-pressed rubber compound and cord will rotate backwards. At the same time, the untreated rubber compound and cord will be conveyed to the surface of the tire three-dimensional forming device from the rubber conveying roller or the cord forming sleeve; S7. Repeat the above steps until the manufacture of the cord fabric layer is completed; S8. Extract the gas in the inner core to make it shrink. At the same time, after removing the positioning screw rod, the inner tire engaging arc-shaped block fixedly installed on the side of the extension rod is quickly driven to retract under the action of the return spring, and then it and the inner core are withdrawn from the formed cord fabric layer; S9. Transfer the formed cord fabric layer and arrange the tread and sidewall rubber, then perform the curing and forming of the whole tire.
