Description

Technical Field

[0001] The present application relates to the technical field of tire wire ring manufacturing, and in particular to a pre-bending adjustment system and method for manufacturing a tire wire ring. Background Art

[0002] A tire bead is a metal ring structure used to fix a tire. It is usually made of high-strength steel wire, has high hardness and tensile strength, and can withstand the huge force and pressure generated when the vehicle is driving. The tire bead is overlapped with the tire sidewall to tightly connect the tire and the vehicle's wheel, ensuring the stability and safety of the vehicle during driving. At the same time, the tire bead can also provide certain support and protection to prevent the tire from deforming or falling off. Pre-bending adjustment is very important in the production process of tire bead, which can improve the performance and safety of the tire as well as manufacturing efficiency.

[0003] For example, in the existing Chinese patent with the publication number CN215279689U, a pre-bending adjustment device for manufacturing tire wire rings is disclosed, which includes a pre-bending mounting seat, two pre-bending adjustment frames and an inclined plate are connected to the top of the pre-bending mounting seat, the end of the inclined plate away from the pre-bending adjustment frame is connected to a mounting plate, the top of the mounting plate is connected to an adjustment plate, the top of the adjustment plate is provided with an adjustment mechanism, and the top of the pre-bending mounting seat is provided with a guide mechanism. Through the above-mentioned prior art, the adjustment mechanism is set up, the fixed handle is rotated, and the adjustment rod on the adjustment dial and the fixed block thread are driven to loosen or tighten, ensuring that the front guide wheel and the rear guide wheel on the fixed block are adjusted up and down in the installation groove, and adjusted to a suitable height for use; because the fixed plate is slidably installed in the sliding connection groove through the sliding block, when pre-bending is required, it can be adjusted to different heights of pre-bending.

[0004] However, the above prior art has the following technical defects: When the above-mentioned prior art is used, the adjustment lever on the adjustment dial and the fixed block thread are first rotated to loosen and tighten, so as to adjust the front guide wheel and the rear guide wheel on the fixed block to move up and down, so as to adjust to a suitable height for use; and when the pre-bending degree needs to be adjusted, the staff pushes the pre-bending rotating wheel as needed to move it to a suitable position, and then adjusts the tire wire ring to the inside of the pre-bending rotating groove of a suitable circular diameter for use. When the above-mentioned device is adjusted accordingly, the staff is required to manually complete the adjustment in sequence, which not only fails to ensure the accuracy of the adjustment, but also reduces the production efficiency of the tire wire ring.

[0005] And when performing pre-bending of different degrees, it is necessary to constantly adjust and push the pre-bending rotating wheel to a suitable position, and then adjust the tire bead to the pre-bending rotating groove that meets the requirements, so that it can be applied to the pre-bending of different degrees of tire bead. As a result, the adjustment work of the device is relatively cumbersome, and the staff needs to manually adjust it throughout the process.

[0006] Based on this, on the basis of the existing pre-bending adjustment device for manufacturing tire wire rings, in order to overcome the above-mentioned technical defects, there is still room for improvement. Summary of the invention

[0037] The following is combined with Figure 1-Figure 15 This application is described in further detail.

[0038] The embodiment of the present application discloses a pre-bending adjustment system and method for manufacturing a tire wire ring, which can conveniently adjust the pre-bending of the tire wire ring as needed, understand the numerical changes during the adjustment in real time to ensure the accuracy of the adjustment, and can efficiently and quickly adjust the relevant components synchronously according to different production requirements. Example

[0039] Reference Figure 1 and Figure 2 As shown, in the first aspect, the present application provides a pre-bending adjustment system for manufacturing tire bead rings, comprising a bottom bracket 1 and a pre-bending adjustment plate 12 mounted on the bottom bracket 1 through two stable side rods 11, and the pre-bending adjustment plate 12 can be stably erected on the bottom bracket 1 under the action of the two stable side rods 11. A pre-bending device 2 is provided on the bottom bracket 1 and the pre-bending adjustment plate 12. When manufacturing tire bead rings, the pre-bending degree of the steel wire can be accurately and quickly adjusted according to different bending requirements.

[0040] The pre-bending device 2 includes an assembly rod seat 21 arranged on one side of the stable side rod 11 and the bottom bracket 1. A driving cylinder 22 is installed on the side of the assembly rod seat 21 facing the pre-bending adjustment plate 12. It should be noted that the telescopic end of the driving cylinder 22 is arranged toward the pre-bending adjustment plate 12; the telescopic end of the driving cylinder 22 is provided with a conical cylinder 24 through an inner cross plate 23. It should be noted that the inner cross plate 23 is located inside the conical cylinder 24, so that the driving cylinder 22 can drive the conical cylinder 24 more smoothly when it is started. A configuration circular hole 121 matching the maximum outer diameter of the conical cylinder 24 is opened through the pre-bending adjustment plate 12. In the initial state, a part of the conical cylinder 24 is in the configuration circular hole 121. A diameter reducing mechanism 3 matching the conical cylinder 24 and a conveying unit 4 matching the diameter reducing mechanism 3 located on one side of the configuration circular hole 121 are provided at the configuration circular hole 121 of the pre-bending adjustment plate 12. The conveying unit 4 is used to match the introduction and export of the steel wire. The conical abutment tube 24 is made of metal with a smooth outer surface and will not deform during use.

[0041] During operation, first, one end of the steel wire used to make the tire wire ring passes through the conveying unit 4 and then wraps around the corresponding component of the diameter-changing mechanism 3, and finally passes out again through the conveying unit 4 to arrange the steel wire on this device; during production, the outgoing end of the steel wire is pulled by an external device, and the steel wire moves on the conveying unit 4 and the diameter-changing mechanism 3. Then, according to the pre-bending production requirements, the driving cylinder 22 is started to push the conical stopper 24 to slide in the direction of the configured circular hole 121, so as to drive the diameter-changing mechanism 3 to operate for pre-bending adjustment, and synchronously drive the conveying unit 4 to make corresponding coordinated adjustments to adapt to the introduction and export of steel wires with different bending degrees.

[0042] Reference Figure 3 and Figure 4As shown, considering the need to adjust different pre-bending degrees according to different requirements when making tire wire rings, the diameter-changing mechanism 3 includes an assembly side ring 31, a driven unit 5 and an indicating assembly 6; the assembly side ring 31 is embedded in the side of the pre-bending adjustment plate 12 away from the assembly rod seat 21, and is located at the configuration hole 121. It should be noted that the inner diameter of the assembly side ring 31 matches the diameter of the configuration hole 121, and when the tapered push cylinder 24 moves toward the configuration hole 121, it will not cause obstruction to the tapered push cylinder 24; the pre-bending adjustment plate 12 is provided with an embedded annular groove 122 for installing the assembly side ring 31. In this embodiment, preferably, sixteen T-shaped inner rods 32 are equidistantly slidably arranged on the assembly side ring 31 in an annular distribution, and sixteen T-shaped slide grooves 311 are provided on the assembly side ring 31 for limiting the installation of the T-shaped inner rods 32.

[0043] The driven unit 5 is arranged on the T-shaped inner rod 32, and is used to cooperate with the tapered anti-tube 24 and realize the surrounding arrangement of the steel wire; the indicating component 6 is arranged on the assembly side ring 31 and the T-shaped inner rod 32, and is used to provide real-time feedback of the changing values ​​to the staff during the pre-bending adjustment, so as to help achieve more precise adjustment.

[0044] Reference Figure 5 and Figure 6 As shown, since it is necessary to cooperate with the tapered abutment cylinder 24 and adjust the multiple T-shaped inner rods 32 synchronously, the driven unit 5 includes a push spring 51 and an end roller 52; in this embodiment, preferably, sixteen push springs 51 are respectively arranged in sixteen T-shaped slide grooves 311 and connected to the upper ends of the T-shaped inner rods 32, and the push springs 51 always have a driving force to push the T-shaped inner rods 32 to slide toward the center of the configuration circular hole 121; the sixteen end rollers 52 are respectively rotatably arranged at one end of the sixteen T-shaped inner rods 32 away from the push springs 51, and under the action of the push springs 51, the end of the T-shaped inner rod 32 with the end roller 52 installed will always contact the tapered abutment cylinder 24. A driven round roller 54 is rotatably arranged on one side of the T-shaped inner rod 32 through an L-shaped stop rod 53. The driven round roller 54 can rotate under force, while the L-shaped stop rod 53 remains unchanged.

[0045] Since the T-shaped inner rod 32 always has one end in contact with the conical resistance cylinder 24 under the action of the push spring 51, the multiple driven rollers 54 installed on the sixteen T-shaped inner rods 32 form a circular ring shape, and the steel wire can be arranged in a circle on the circular ring formed by the multiple driven rollers 54.

[0046] Reference Figure 7As shown, in order to enable the staff to understand the changes in the adjustment value in real time when performing pre-bending variable diameter adjustment and achieve precise adjustment to better meet the requirements during production, the indicator component 6 includes an indicator arrow 61 installed on one of the T-shaped inner rods 32, and a rectangular sliding opening 312 connected to one of the T-shaped sliding grooves 311 for the installation of the indicator arrow 61 is opened on the assembly side ring 31, and a circular diameter scale 313 is opened on the assembly side ring 31 located on one side of the rectangular sliding opening 312.

[0047] When pre-bending adjustment is required during the manufacturing process of the tire wire ring, it is only necessary to start the driving cylinder 22 to push the conical cylinder 24 to move. Under the interference between the inclined surface of the conical cylinder 24 and the end roller 52, the circular ring composed of multiple driven rollers 54 can be adjusted to different degrees of diameter change; when the conical cylinder 24 moves toward the configuration circular hole 121, it can drive multiple T-shaped inner rods 32 to shrink synchronously into the T-shaped chute 311, thereby causing the circular ring composed of multiple driven rollers 54 to become larger, and conversely, multiple T-shaped inner rods 32 synchronously extend out of the T-shaped chute 311, so that the circular ring composed of multiple driven rollers 54 becomes smaller. Thus, the effect of pre-bending adjustment of the surrounding wire ring is achieved; the smaller the circular ring composed of multiple driven rollers 54, the greater the bending degree of the surrounding wire ring after being led out, and conversely, the larger the circular ring composed of multiple driven rollers 54, the smaller the bending degree of the surrounding wire ring after being led out.

[0048] Since the indicator arrow 61 is installed on one of the T-shaped inner rods 32, it can slide in the rectangular sliding opening 312 synchronously with the movement of the T-shaped inner rod 32. The staff can refer to the circular diameter scale 313 to understand the precise numerical changes of the adjusted circular diameter in real time, thereby facilitating the staff to drive the driving cylinder 22 to perform more precise variable diameter pre-bending adjustments.

[0049] Reference Figure 8 and Fig. 9 As shown, in order to better cooperate with the diameter-changing mechanism 3 to complete the introduction and lead-out of the steel wire during pre-bending, the conveying unit 4 includes two T-shaped support blocks 41 which are limitedly slidably arranged on the pre-bending adjustment plate 12, and a rectangular vertical groove 123 for installing the two T-shaped support blocks 41 is opened through the pre-bending adjustment plate 12, and an introduction wheel 42 and an outlet wheel 43 are rotatably installed on one side of the two T-shaped support blocks 41.

[0050] The lead-in wheel 42 and the lead-out wheel 43 can rotate when subjected to force; when arranging the steel wire, one end of the steel wire is first passed through the lead-in wheel 42, then wrapped around a circle on a ring composed of a plurality of driven circular rollers 54, and finally passed out through the lead-out wheel 43.

[0051] Continue to refer to Fig. 9As shown, the inner thread of the rectangular vertical groove 123 of the pre-bending adjustment plate 12 passes through the two T-shaped support blocks 41 and is rotatably provided with a bidirectional threaded rod 44. The T-shaped support block 41 passes through the thread to open an inner threaded hole 411 that is compatible with the bidirectional threaded rod 44. A transmission gear 45 is sleeved on the middle part of the bidirectional threaded rod 44. When the transmission gear 45 is driven, it can drive the bidirectional threaded rod 44 to rotate. In cooperation with the inner threaded hole 411 opened in the T-shaped support block 41, the two T-shaped support blocks 41 can be driven to synchronously slide relative to each other in the rectangular vertical groove 123; the pre-bending adjustment plate 12 is provided with a linkage component 7 that cooperates with the conical push cylinder 24 for transmission, which is used to cooperate with the conical push cylinder 24 to drive the transmission gear 45.

[0052] Reference Fig. 9 and Fig.10 As shown, in order to make the spacing between the introduction wheel 42 and the output wheel 43 adaptively adjusted accordingly to cooperate with the diameter-changing mechanism 3 while performing the pre-bending variable diameter adjustment, so as to better introduce and export the steel wires with different bending degrees, the linkage assembly 7 includes a dovetail rack 71 which is limitedly slidably arranged in the pre-bending adjustment plate 12 and meshed with the transmission gear 45, and the pre-bending adjustment plate 12 is provided with a limited slide groove 124 which is connected with the rectangular vertical groove 123 and the configuration circular hole 121 for the installation of the dovetail rack 71, and a return spring 72 is installed in the limited slide groove 124 of the pre-bending adjustment plate 12, and one end of the return spring 72 is connected to the end of the dovetail rack 71, and the return spring 72 always has a driving force to push the dovetail rack 71 to slide in the direction of the configuration circular hole 121. A transmission rod 73 is arranged at one end of the dovetail rack 71 away from the return spring 72. A transmission round wheel 74 is rotatably installed at one end of the transmission rod 73 toward the conical cylinder 24. Driven by the return spring 72 , the driving wheel 74 always contacts the outer surface of the conical abutment cylinder 24 .

[0053] Whenever the conical cylinder 24 is driven to move, the dovetail rack 71 can be driven to slide in the limiting slide groove 124 under the contact between the transmission round wheel 74 and the inclined surface of the conical cylinder 24 and the driving action of the reset spring 72, so as to drive the transmission gear 45 and the bidirectional threaded rod 44 to rotate. When the conical cylinder 24 slides toward the configuration circular hole 121, the dovetail rack 71 can be driven to slide toward the reset spring 72, and the reset spring 72 contracts. At this time, the distance between the two T-shaped support blocks 41 becomes larger, that is, the distance between the introduction wheel 42 and the output wheel 43 becomes larger, so as to adapt to the introduction and output of the steel wire with a small curvature; on the contrary, the dovetail rack 71 slides toward the configuration circular hole 121 driven by the reset spring 72. At this time, the distance between the two T-shaped support blocks 41 becomes smaller, that is, the distance between the introduction wheel 42 and the output wheel 43 becomes smaller, so as to adapt to the introduction and output of the steel wire with a large curvature. Example

[0054] Reference Figures 11 to 13As shown, on the basis of Example 1, since the steel wire is wrapped around multiple driven rollers 54, rust powder, dirt, etc. on the steel wire are easily attached to the driven rollers 54. If they are not cleaned in time, the long-term adhesion and accumulation will affect the pre-bending state of the steel wire ring during production. In order to be able to quickly and effectively clean the multiple driven rollers 54, a synchronous cleaning component 8 is also provided on the pre-bending adjustment plate 12. The synchronous cleaning component 8 includes a positioning support rod 81 installed on one side of the pre-bending adjustment plate 12, and the positioning support rod 81 has a positioning groove 811. The positioning support rod 81 is located at the positioning groove 811 and is detachably provided with a cleaning outer ring 83 by assembling bolts 82. A driving turntable 84 is rotatably provided on the cleaning outer ring 83. It should be noted that after the cleaning outer ring 83 is installed on the positioning support rod 81, the driving turntable 84 conflicts with the multiple driven rollers 54 at the initial position.

[0055] It should be noted that the cleaning outer ring 83 is installed on the positioning support rod 81 only when the driven roller 54 needs to be cleaned, so as to block the movement of the conical cylinder 24 during normal manufacturing work.

[0056] The driving turntable 84 is provided with a plurality of rectangular through holes 841 in an annular shape, and a plurality of cleaning blades 85 are equidistantly arranged in an annular shape on the side of the cleaning outer ring 83 facing the configuration circular hole 121, preferably sixteen cleaning blades 85. It should be noted that after the cleaning outer ring 83 is installed on the positioning support rod 81, the sixteen cleaning blades 85 will conflict with the sixteen driven circular rollers 54 at the initial position.

[0057] When cleaning is needed and the cleaning outer ring 83 is installed, the driving turntable 84 is rotated to drive the multiple driven rollers 54 to rotate, and the outer circumferential surface of the driven rollers 54 can be cleaned in conjunction with the cleaning scraper 85; some of the cleaned pollutants will fall into the driving turntable 84, and during the rotation of the driving turntable 84, the fallen pollutants can be discharged outward through the rectangular through hole 841 to avoid a large amount of pollutants accumulating in the driving turntable 84.

[0058] Reference Fig.14 As shown, a collecting box 87 is slidably mounted on the bottom bracket 1 below the configuration circular hole 121 through a T-shaped bar 86, and a transverse slide 101 is provided on the bottom bracket 1 for the sliding installation of the T-shaped bar 86. The pollutants that are cleaned and dropped can fall into the collecting box 87 and be collected and stored for subsequent unified removal.

[0059] Reference Fig.15 As shown, on the other hand, the present application also discloses a pre-bending adjustment method for manufacturing a tire wire ring, and the steps of the adjustment method are as follows: The first step is steel wire arrangement: first, one end of the steel wire used in the production is passed through the conveying unit 4 and then wrapped around the corresponding component of the diameter-changing mechanism 3, and finally transmitted out through the conveying unit 4 again; specifically, one end of the steel wire is first passed through the introduction wheel 42 and then wrapped around a circle on a ring composed of multiple driven circular rollers 54, and finally transmitted out through the output wheel 43.

[0060] The second step is pre-bending adjustment: according to the different pre-bending degrees of the wire ring during production, the corresponding starting driving cylinder 22 pushes the conical cylinder 24 to adjust the diameter-changing mechanism 3; when the conical cylinder 24 moves toward the configuration circular hole 121, it can drive the circular ring composed of the multiple driven circular rollers 54 to become larger, and vice versa, the circular ring composed of the multiple driven circular rollers 54 becomes smaller, thereby achieving the effect of adjusting the pre-bending degree of the surrounding wire ring.

[0061] The third step is numerical response: the numerical change during adjustment will be fed back to the staff in real time through the indicator component 6; since the indicator arrow 61 is installed on one of the T-shaped inner rods 32, it can synchronously follow the T-shaped inner rod 32 to slide in the rectangular sliding mouth 312. The staff can refer to the circular diameter scale 313 to understand the precise numerical change of the adjustment circular diameter in real time, thereby facilitating the staff to drive the driving cylinder 22 to perform more precise variable diameter pre-bending adjustment.

[0062] The fourth step is synchronous adjustment: while adjusting the diameter-changing mechanism 3, the conveying unit 4 is adjusted synchronously under the action of the linkage assembly 7 to cooperate with the adaptive introduction and export of the steel wire; when the tapered cylinder 24 slides toward the configuration circular hole 121, the spacing between the introduction wheel 42 and the export wheel 43 can be driven to increase to adapt to the introduction and export of the steel wire with a small degree of curvature; conversely, driven by the reset spring 72, the spacing between the two T-shaped support blocks 41 becomes smaller, that is, the spacing between the introduction wheel 42 and the export wheel 43 becomes smaller to adapt to the introduction and export of the steel wire with a large degree of curvature.

[0063] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
