Description

Technical Field

[0001] This application relates to the technical field of tire bead manufacturing, and particularly to a pre-bending adjustment system and method for tire bead manufacturing. Background Art

[0002] A tire bead refers to 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 forces and pressures generated during vehicle driving. The tire bead is closely connected to the vehicle wheel through the lap joint with the tire wall, ensuring the stability and safety of the vehicle during driving. At the same time, the tire bead can also provide certain support and protection functions to prevent the tire from deforming or falling off. And pre-bending adjustment is very important in the process of tire bead manufacturing, which can improve the performance and safety of the tire as well as the manufacturing efficiency.

[0003] For example, in the existing Chinese patent with the publication number CN215279689U, it discloses a pre-bending adjustment device for tire bead manufacturing, 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, and an adjustment plate is connected to the top of the mounting plate. An adjustment mechanism is arranged on the top of the adjustment plate, and a guiding mechanism is arranged on the top of the pre-bending mounting seat. Through the above-mentioned prior art, with the arranged adjustment mechanism, by rotating the fixing handle, the adjustment rod on the adjustment turntable is screwed loose or tight with the fixed block, ensuring that the front guiding wheel and the rear guiding wheel on the fixed block move up and down inside the installation groove, and adjusting to a suitable height for use; because the fixing plate is slidably installed inside the sliding connection groove through the sliding block, when pre-bending is required, it can be adjusted to different heights for pre-bending.

[0004] However, the above prior art has the following technical defects:

[0005] When the above prior art is in use, first, by rotating the fixing handle to drive the adjustment rod on the adjustment turntable to be screwed loose or tight with the fixed block, the front guiding wheel and the rear guiding wheel on the fixed block can move up and down 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 according to the need to move it to a suitable position, and then adjusts the tire bead into the pre-bending rotating groove with a suitable circular diameter for use. When the above device makes corresponding adjustments, the staff needs to manually complete the adjustments one by one. The adjustment accuracy cannot be guaranteed, and at the same time, the manufacturing efficiency of the tire bead is reduced.

[0006] And when making pre-bends of different degrees, it is necessary to continuously adjust and move the pre-bending rotating wheel to a suitable position, and then adjust the tire bead wire to the pre-bending rotating groove that meets the requirements before it can be applied to the pre-bending production work of tire bead wires of different degrees. As a result, the adjustment work of the device is relatively cumbersome and requires manual adjustment by the staff throughout the process.

[0007] Based on this, on the basis of an existing pre-bending adjustment device for tire bead wire production, in order to overcome the above technical defects, there is still room for improvement. Summary of the Invention

[0008] In order to conveniently adjust the pre-bending production of tire bead wires as needed, to understand the numerical changes during adjustment in real time to ensure the accuracy of adjustment, and to be able to synchronously adjust relevant components efficiently and quickly according to different production requirements, this application provides a pre-bending adjustment system and method for tire bead wire production.

[0009] In the first aspect, a pre-bending adjustment system for tire bead wire production provided by this application adopts the following technical solutions:

[0010] A pre-bending adjustment system for tire bead wire production includes a bottom bracket and a pre-bending adjustment plate installed on the bottom bracket through two stable side rods, and a pre-bending device is provided on the bottom bracket and the pre-bending adjustment plate;

[0011] The pre-bending device includes an assembly rod seat arranged on one side of the stable side rod and the bottom bracket.

[0012] Preferably, the variable diameter mechanism includes an assembly side ring, a driven unit and an indicating component. The assembly side ring is embedded on the side of the pre-bending adjustment plate away from the assembly rod seat and is located at the configuration round hole. An embedding ring groove for installing the assembly side ring is opened on the pre-bending adjustment plate. A number of T-shaped inner rods are slidably arranged at equal intervals in a circular distribution on the assembly side ring. A number of T-shaped sliding grooves for limiting and installing the T-shaped inner rods are opened on the assembly side ring. The driven unit is arranged on the T-shaped inner rods, and the indicating component is arranged on the assembly side ring and the T-shaped inner rods.

[0013] Preferably, the driven unit includes a pushing spring and an end roller. A plurality of the pushing springs are respectively arranged in a plurality of T-shaped chutes and connected to the upper end of the T-shaped inner rod. A plurality of the end rollers are respectively rotatably arranged at one end of the plurality of T-shaped inner rods away from the pushing spring. One side of the T-shaped inner rod is rotatably provided with a driven round roller through an L-shaped stop rod.

[0014] Preferably, the indicating component includes an indicating arrow installed on one of the T-shaped inner rods. A rectangular sliding opening communicating with one of the T-shaped chutes for installing the indicating arrow is formed on the assembling side ring. Circular scale graduations are formed on the assembling side ring on one side of the rectangular sliding opening.

[0015] Preferably, the conveying unit includes two T-shaped supporting blocks which are limited and slidably arranged on the pre-bending adjusting plate. A rectangular vertical groove for installing the two T-shaped supporting blocks is formed through the pre-bending adjusting plate. One side of each of the two T-shaped supporting blocks is respectively rotatably installed with a guiding wheel and a discharging wheel.

[0016] Preferably, a bidirectional threaded rod is rotatably arranged through the two T-shaped supporting blocks in the rectangular vertical groove of the pre-bending adjusting plate. The T-shaped supporting blocks are threadedly provided with internal threaded holes adapted to the bidirectional threaded rod through threads. A transmission gear is sleeved in the middle of the bidirectional threaded rod. A linkage assembly for cooperating with the conical abutting cylinder for transmission is arranged in the pre-bending adjusting plate.

[0017] Preferably, the linkage assembly includes a dovetail rack which is limited and slidably arranged in the pre-bending adjusting plate and meshes with the transmission gear. A limiting chute for installing the dovetail rack and communicating with the rectangular vertical groove and the configuration circular hole is formed on the pre-bending adjusting plate. A return spring is installed in the limiting chute of the pre-bending adjusting plate, and one end of the return spring is connected to the end of the dovetail rack. A conduction abutting rod is arranged at one end of the dovetail rack away from the return spring.

[0018] Preferably, a transmission round roller is rotatably installed at one end of the conduction abutting rod facing the conical abutting cylinder.

[0019] Preferably, the conical abutting cylinder is made of a metal material with a smooth outer surface.

[0020] In a second aspect, the present application also discloses a pre-bending adjustment method for manufacturing a tire bead wire. The adjustment method includes the following steps:

[0021] The first step, wire arrangement: First, one end of the wire used for manufacturing is passed through the conveying unit and then wound around the corresponding components of the variable diameter mechanism for one circle, and finally passed out through the conveying unit again.

[0022] The second step, pre-bending adjustment: According to the different pre-bending degrees during the manufacturing of the wire bead, the driving cylinder is correspondingly started to push the conical abutting cylinder to adjust the variable diameter mechanism.

[0023] Step 3, numerical response: The numerical changes during adjustment will be fed back to the staff in real time through the indicating component;

[0024] Step 4, synchronous adjustment: While adjusting the variable diameter mechanism, the conveying unit is synchronously adjusted under the action of the linkage component to cooperate with the adaptive introduction and export of the steel wire.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] Under the action of the pushing spring, the end of the T-shaped inner rod with the end roller will always abut against the outer side wall of the conical abutting cylinder in the configured circular hole. Since the ends of multiple T-shaped inner rods abut against the conical abutting cylinder at the same time, multiple driven rollers installed on the multiple T-shaped inner rods will be combined into a ring shape for the steel wire to be wound around the multiple driven rollers.

[0027] Since the conical abutting cylinder is conical and made of a metal material with a smooth outer surface, when the driving cylinder is started to push the conical abutting cylinder towards the configured circular hole, under the abutting action of the inclined outer surface of the conical abutting cylinder and the end of the T-shaped inner rod with the end roller, multiple T-shaped inner rods can be synchronously and uniformly retracted into the T-shaped chute, so that the ring formed by multiple driven rollers can be gradually expanded, that is, the effect of variable diameter is achieved.

[0028] While the conical abutting cylinder is driven by the driving cylinder to move, it will also abut against the outer surface of the conical abutting cylinder through the transmission wheel due to the action of the return spring, thereby driving the dovetail rack to slide in the limit chute to drive the bidirectional threaded rod to rotate through the transmission gear. Under the cooperation of the rotating bidirectional threaded rod and the internal threaded hole opened on the T-shaped support block, the two T-shaped support blocks can be driven to move relatively in the rectangular vertical groove synchronously, achieving the effect of adjusting the circular diameter of the ring formed by multiple driven rollers and correspondingly adjusting the distance between the inlet wheel and the outlet wheel at the same time, so as to better cooperate with the variable diameter mechanism for the adaptive introduction and export of the steel wire.

Detailed implementation manners

[0045] The following will Figures 1 - 15 further elaborate on this application in detail.

[0046] The embodiment of this application discloses a pre-bending adjustment system and method for manufacturing tire bead wires, which can conveniently adjust the pre-bending of tire bead wires as needed, understand the numerical changes during adjustment in real time to ensure the accuracy of adjustment, and can synchronously adjust relevant components efficiently and quickly according to different manufacturing requirements. Embodiment

[0047] Referring to Figure 1 and Figure 2 As shown, in the first aspect, this application provides a pre-bending adjustment system for manufacturing tire bead wires, including a bottom bracket 1 and a pre-bending adjustment plate 12 installed on the bottom bracket 1 through two stable side rods 11. Under the action of the two stable side rods 11, the pre-bending adjustment plate 12 can be stably erected on the bottom bracket 1. A pre-bending device 2 is provided on the bottom bracket 1 and the pre-bending adjustment plate 12. When manufacturing tire bead wires, it can accurately and quickly adjust the pre-bending degree of the wire according to different bending requirements.

[0048] The pre-bending device 2 includes an assembly rod base 21 provided on one side of the stable side rod 11 and the bottom bracket 1. On the side of the assembly rod base 21 facing the pre-bending adjustment plate 12, a driving cylinder 22 is installed. It should be noted that the telescopic end of the driving cylinder 22 is arranged towards the pre-bending adjustment plate 12; a conical abutting cylinder 24 is arranged at the telescopic end of the driving cylinder 22 through an inner cross plate 23. It should be noted that the inner cross plate 23 is located inside the conical abutting cylinder 24 so that the driving cylinder 22 can drive the conical abutting cylinder 24 more smoothly when starting. A configuration round hole 121 adapted to the maximum outer diameter of the conical abutting cylinder 24 is penetrated through the pre-bending adjustment plate 12. In the initial state, a part of the conical abutting cylinder 24 is located in the configuration round hole 121. A variable diameter mechanism 3 cooperating with the conical abutting cylinder 24 and a conveying unit 4 cooperating with the variable diameter mechanism 3 on one side of the configuration round hole 121 are provided at the configuration round hole 121 of the pre-bending adjustment plate 12. The conveying unit 4 is used to cooperate with the introduction and export of the steel wire. The conical abutting cylinder 24 is made of a metal material with a smooth outer surface and will not deform during use.

[0049] During operation, first, one end of the steel wire for making the tire bead is passed through the conveying unit 4 and then wound around the corresponding components of the variable diameter mechanism 3 in a circle, and finally passed out through the conveying unit 4 again to arrange the steel wire on this equipment; 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 variable diameter mechanism 3. Subsequently, according to the pre-bending production requirements, the driving cylinder 22 is started to push the conical abutting cylinder 24 to slide towards the configuration round hole 121, so as to drive the variable diameter mechanism 3 to operate for pre-bending adjustment. Synchronously, the conveying unit 4 will also be driven to make corresponding cooperative adjustments to adapt to the introduction and export of steel wires with different bending degrees.

[0050] Refer to Figure 3 and Figure 4 As shown, considering that it is necessary to adjust the different pre-bending degrees according to different requirements during the production of the tire bead, the variable diameter mechanism 3 includes an assembly side ring 31, a driven unit 5, and an indication component 6; the assembly side ring 31 is embedded on the side of the pre-bending adjustment plate 12 away from the assembly rod base 21 and is located at the configuration round hole 121. It should be noted that the inner diameter of the assembly side ring 31 matches the diameter of the configuration round hole 121, and when the conical abutting cylinder 24 moves towards the configuration round hole 121, it will not hinder the conical abutting cylinder 24; an embedding ring groove 122 for installing the assembly side ring 31 is opened on the pre-bending adjustment plate 12. In this embodiment, preferably, sixteen T-shaped inner rods 32 are arranged on the assembly side ring 31 in an equidistant and sliding manner in a circular distribution, and sixteen T-shaped sliding grooves 311 for limiting the installation of the T-shaped inner rods 32 are opened on the assembly side ring 31.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] Reference Figure 7 As 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.

[0055] 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.

[0056] 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.

[0057] Reference Figure 8 and Figure 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.

[0058] 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.

[0059] Continue to refer to Figure 9 As 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.

[0060] Referring to Figure 9 and Figure 10 As shown, in order to adaptively adjust the distance between the inlet wheel 42 and the outlet wheel 43 to cooperate with the diameter-changing mechanism 3 while performing pre-bending diameter adjustment, so as to better introduce and export the steel wire with different bending degrees, the linkage assembly 7 includes a dovetail rack 71 which is limited and slidably arranged in the pre-bending adjustment plate 12 and meshes with the transmission gear 45. A limit sliding groove 124 communicating with the rectangular vertical groove 123 and the configured circular hole 121 is formed on the pre-bending adjustment plate 12 for installing the dovetail rack 71. A return spring 72 is installed in the limit sliding 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. The return spring 72 always has a driving force to push the dovetail rack 71 to slide towards the configured circular hole 121. A conduction abutting 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 conduction abutting rod 73 facing the conical abutting cylinder 24. Driven by the return spring 72, the transmission round wheel 74 always abuts against the outer surface of the conical abutting cylinder 24.

[0061] Whenever the conical abutting cylinder 24 is driven to move, under the abutment of the transmission round wheel 74 and the inclined surface of the conical abutting cylinder 24 and the driving action of the cooperation of the return spring 72, the dovetail rack 71 can be driven to slide in the limit sliding groove 124, so as to drive the transmission gear 45 and the bidirectional threaded rod 44 to rotate. When the conical abutting cylinder 24 slides towards the configured circular hole 121, the dovetail rack 71 can be driven to slide towards the return spring 72, and the return spring 72 contracts. At this time, the distance between the two T-shaped supporting blocks 41 becomes larger, that is, the distance between the inlet wheel 42 and the outlet wheel 43 becomes larger, so as to adapt to the introduction and export of the steel wire with a small bending degree; on the contrary, the dovetail rack 71 slides towards the configured circular hole 121 under the drive of the return spring 72. At this time, the distance between the two T-shaped supporting blocks 41 becomes smaller, that is, the distance between the inlet wheel 42 and the outlet wheel 43 becomes smaller, so as to adapt to the introduction and export of the steel wire with a large bending degree. Embodiment

[0062] Referring to 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] Reference Figure 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.

[0067] Reference Figure 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:

[0068] The first step, wire arrangement: First, one end of the wire used in the production passes through the conveying unit 4 and then loops around the corresponding component of the diameter-changing mechanism 3, and finally passes out through the conveying unit 4 again; specifically, one end of the wire first passes through the guiding wheel 42 and then loops around a ring composed of a plurality of driven round rollers 54, and finally passes out through the guiding-out wheel 43.

[0069] The second step, pre-bending adjustment: According to the different pre-bending degrees during the production of this wire loop, the driving cylinder 22 is correspondingly activated to push the conical abutting cylinder 24 to adjust the diameter-changing mechanism 3; when the conical abutting cylinder 24 moves towards the direction of the configured circular hole 121, it can drive the ring composed of a plurality of driven round rollers 54 to become larger, and vice versa, the ring composed of a plurality of driven round rollers 54 becomes smaller. Thus, the effect of adjusting the pre-bending degree of the wound wire loop is achieved.

[0070] The third step, numerical response: The numerical changes during the adjustment will be fed back to the staff in real time through the indicating component 6; since the indicating arrow 61 is installed on one of the T-shaped inner rods 32, it can slide synchronously with the T-shaped inner rod 32 in the rectangular sliding opening 312, and the staff can cooperate with the reference of the circular diameter scale 313 to understand the precise numerical changes of the adjusted circular diameter in real time, so as to facilitate the staff to drive the driving cylinder 22 to perform more precise diameter-changing pre-bending adjustment.

[0071] The fourth step, synchronous adjustment: While adjusting the diameter-changing mechanism 3, under the action of the linkage component 7, the conveying unit 4 is synchronously adjusted to cooperate with the adaptive introduction and export of the wire; when the conical abutting cylinder 24 slides towards the direction of the configured circular hole 121, it can drive the distance between the guiding wheel 42 and the guiding-out wheel 43 to become larger to adapt to the introduction and export of the wire with a small bending degree; on the contrary, under the drive of the return spring 72, the distance between the two T-shaped supporting blocks 41 becomes smaller, that is, the distance between the guiding wheel 42 and the guiding-out wheel 43 becomes smaller to adapt to the introduction and export of the wire with a large bending degree.

[0072] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
