Method and apparatus for wire winding of rubber hoses

Abstract

This invention discloses a method and apparatus for winding steel wires into a rubber hose, relating to the field of rubber hose technology. The method includes the following steps: Step 1: Fixing the inner rubber tube to maintain a horizontal position; Step 2: Connecting the ends of each steel wire to the inner rubber tube; Step 3: Driving the steel wires to rotate relative to the inner rubber tube while simultaneously performing axial translation; Step 4: Removing the wound inner rubber tube. The above method is accomplished using a rubber hose steel wire winding apparatus, including a rotating shaft assembly. The rotating shaft assembly includes two symmetrically arranged first arc-shaped plates and two symmetrically arranged second arc-shaped plates. Because the inner rubber tube experiences very little dynamic friction as the first and second arc-shaped plates move radially towards the inner rubber tube, the possibility of wrinkles and twists in the inner rubber tube is greatly reduced, ensuring that the inner rubber tube can tightly adhere to the first and second arc-shaped plates.

Description

Technical Field

[0001] This invention relates to the field of rubber hose technology, specifically to a method and apparatus for winding steel wire around a rubber hose. Background Technology

[0002] Steel wire braided rubber hoses are high-strength and pressure-resistant hoses composed of an inner rubber layer, a steel wire braided layer, and an outer rubber layer. The inner rubber layer possesses excellent wear resistance, oil resistance, and high-temperature resistance, capable of withstanding high-temperature and high-pressure media such as oil, water, and gas. The steel wire braided layer enhances the hose's strength and pressure resistance, enabling it to withstand high-pressure impacts and vibrations. The outer rubber layer protects the steel wire braided layer from the effects of the external environment and chemical corrosion. Steel wire braided rubber hoses have a wide range of applications, particularly suitable for various high-pressure conveying, filling, and discharging applications.

[0003] In the production of steel wire braided rubber hoses, multiple steel wires need to be wound around the surface of the inner rubber tube. Existing technologies have already conducted some research on the steel wire winding process. For example, Chinese utility model patent CN214814401U discloses a double-support high-pressure rubber hose steel wire winding machine, including a turntable, a gearbox, a rotating shaft, and a rubber hose. The rubber hose is sleeved on the rotating shaft, which passes through the turntable and the gearbox. The gearbox is located on one side of the turntable, and a rotating assembly is located on the side of the turntable opposite to the gearbox. The steel wires on the turntable are wound around the rubber hose through the rotating assembly, and the rotating assembly is fixed to the ground by a support base. Chinese utility model patent with publication number CN220387748U discloses a rubber hose steel wire winding machine, including a U-shaped fixed support frame. One end of the U-shaped fixed support frame is slidably provided with a sliding block, and the other end is slidably provided with a sliding guide rail, and the two are kept perpendicular to each other. A first pressing frame and a second pressing frame are slidably provided on the U-shaped fixed support frame, and a tension spring assembly is also included. In the default state, the tension spring assembly drives the first pressing frame and the second pressing frame to lock the sliding block and the sliding guide rail.

[0004] Existing wire winding machines, including those mentioned in the patent, use a rotating shaft to internally support the rubber tube during operation. The shaft then moves the rubber tube horizontally to achieve axial winding of the wire. However, for rubber tubes with large diameters or thin walls, the friction between the tube and the shaft is significant, and the tube itself is prone to deformation. This results in wrinkles and twists, making it difficult to achieve a tight fit against the shaft's outer wall. This necessitates multiple manual adjustments, increasing the operator's workload and requiring considerable experience. Therefore, ensuring that the operator can quickly and accurately fit the rubber tube onto the shaft, achieving a tight fit, is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a method and apparatus for winding steel wire into a rubber hose, so as to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for winding steel wire around a rubber hose, comprising the following steps:

[0007] Step 1: Secure the inner rubber tube to keep it horizontal;

[0008] Step 2: Connect the ends of each steel wire to the inner rubber tube;

[0009] Step 3: Simultaneously rotate the driving steel wire relative to the inner rubber tube and perform axial translation;

[0010] Step 4: Remove the inner rubber tube after it has been wrapped.

[0011] The above method is completed using a rubber hose wire winding device, which includes a rotating shaft assembly. The rotating shaft assembly includes two symmetrically arranged first arc-shaped plates and two symmetrically arranged second arc-shaped plates. Both the first arc-shaped plates and the second arc-shaped plates have a first state of mutual contact and a second state of mutual separation.

[0012] As a preferred embodiment of the present invention, the rubber hose wire winding device further includes a base and a translation platform slidably mounted on the base. A horizontal sleeve is fixedly mounted on the translation platform, and several C-shaped frames are uniformly fixedly mounted on the outer wall of the sleeve along its circumference. A wire reel is rotatably mounted on the C-shaped frame.

[0013] As a preferred embodiment of the present invention, the rotating shaft assembly further includes a circular plate coaxial with the sleeve, and a mounting shaft coaxial with the circular plate is rotatably mounted on the circular plate; a first incomplete gear and a second incomplete gear are fixedly sleeved on the mounting shaft; a first rack meshing with the first incomplete gear is fixedly mounted on the first arc plate, and a second rack meshing with the second incomplete gear is fixedly mounted on the second arc plate.

[0014] As a preferred embodiment of the present invention, the circular plate is rotatably mounted on the base via a bracket; a stop bar is fixedly mounted on the circular plate, and a push plate that cooperates with the stop bar is fixedly mounted on the mounting shaft.

[0015] As a preferred embodiment of the present invention, a driven gear ring that rotates synchronously with the mounting shaft is sleeved on the mounting shaft, a drive motor is fixedly mounted on the bracket, and a drive gear ring that meshes with the driven gear ring is fixedly mounted on the output shaft of the drive motor; a lead screw that passes through the translation stage is rotatably mounted on the base through a bearing bracket, and one end of the lead screw is connected to the output shaft of the drive motor through a coupling.

[0016] As a preferred embodiment of the present invention, a first spike is installed on the outer arc surface of the first arc plate, and a second spike is installed on the outer arc surface of the second arc plate.

[0017] As a preferred embodiment of the present invention, the first spike and the second spike are respectively provided with a first through groove and a second through groove; the tip of the first spike is provided with a cut that communicates with the first through groove, and the tip of the second spike is provided with a cut that communicates with the second through groove.

[0018] As a preferred embodiment of the present invention, anti-slip grooves are provided on the outer arc surfaces of both the first arc plate and the second arc plate.

[0019] As a preferred embodiment of the present invention, the wire reel includes a winding portion and round rod portions located at both ends of the winding portion. The round rod portions are rotatably fitted with a U-shaped frame, and the round rod portions and the winding portion are detachably connected. A first pulley is fixedly sleeved on the round rod portion, and a speed limiting shaft parallel to the round rod portion is rotatably mounted on the U-shaped frame. A second pulley is fixedly sleeved on the speed limiting shaft, and the first pulley and the second pulley are connected by a transmission belt. A ring is fixedly mounted on the speed limiting shaft, and a speed limiting block is slidably mounted on the outer circumference of the ring. A circular shell coaxial with the ring is fixedly mounted on the U-shaped frame, and rubber blocks are uniformly fixedly mounted on the inner circumference of the circular shell.

[0020] In the above technical solution, the present invention provides a rubber hose wire winding device, whose rotating shaft assembly includes a first arc plate and a second arc plate. When the operator puts on the inner rubber tube, the first arc plate and the second arc plate are in a separated state. The outer arc surfaces of the first arc plate and the second arc plate do not form a complete circumferential surface, that is, there is a large gap between the inner wall of the inner rubber tube and the outer arc surfaces of the first arc plate and the second arc plate, allowing the operator to quickly put on the inner rubber tube. After the inner rubber tube is put on, the first arc plate and the second arc plate move radially toward the inner rubber tube in sequence, providing internal support for the inner rubber tube, until the outer arc surfaces of the first arc plate and the second arc plate form a complete circumferential surface and are completely in contact with the inner surface of the inner rubber tube. Since the inner rubber tube experiences very little dynamic friction during the radial movement of the first arc plate and the second arc plate toward the inner rubber tube, the possibility of wrinkles and twists in the inner rubber tube is greatly reduced, ensuring that the inner rubber tube can be tightly attached to the first arc plate and the second arc plate.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] This embodiment provides a method for winding steel wire into a rubber hose, including the following steps:

[0036] Step 1: Secure the inner rubber tube to keep it horizontal;

[0037] Step 2: Connect the ends of each steel wire to the inner rubber tube;

[0038] Step 3: Simultaneously rotate the driving steel wire relative to the inner rubber tube and perform axial translation;

[0039] Step 4: Remove the inner rubber tube after it has been wrapped.

[0040] like Figure 1 , Figure 4 and Figure 7 As shown, the above method is completed using a rubber hose wire winding device, including a rotating shaft assembly 1 for supporting and rotating the inner rubber tube; the rotating shaft assembly 1 includes two symmetrically arranged first arc-shaped plates 101 and two symmetrically arranged second arc-shaped plates 102; both the first arc-shaped plates 101 and the second arc-shaped plates 102 are in a first state of mutual contact. Figure 6 As shown), and the second state that is separated from each other ( Figure 7(As shown); anti-slip grooves are provided on the outer arc surfaces of the first arc plate 101 and the second arc plate 102 to increase the friction between them and the inner rubber tube, ensuring that the inner rubber tube can be rotated.

[0041] Specifically, in the first state, the outer edges of the four arc-shaped plates 101 and 102 together form a complete ring, and the outer diameter of the ring is the same as the inner diameter of the inner rubber tube. In the second state, the two second arc-shaped plates 102 are located between the two first arc-shaped plates 101. The distance between the two first arc-shaped plates 101 in the second state is smaller than the distance between them in the first state. The distance between the two second arc-shaped plates 102 in the second state is smaller than the distance between them in the first state.

[0042] During the process of the operator fitting the inner rubber tube onto the rotating shaft assembly 1, initially, the first arc plate 101 and the second arc plate 102 are in the second state, and there is a large gap between the inner rubber tube and the outer walls of the first arc plate 101 and the second arc plate 102. That is, the friction between the inner rubber tube and the rotating shaft assembly 1 is very small during the horizontal fitting of the inner rubber tube along the length of the rotating shaft assembly 1, and the inner rubber tube will not wrinkle or twist due to dynamic friction. After the operator fits the inner rubber tube into the predetermined position, the two... The first two arc-shaped plates 101 initially move away from each other, and the distance between them gradually increases, making room for the movement of the second arc-shaped plate 102. During this process, the second arc-shaped plate 102 contacts the inner wall of the inner rubber tube and stretches the inner rubber tube to a taut state. Then, the two first arc-shaped plates 101 stop moving away from each other, and the two second arc-shaped plates 102 immediately begin to move away from each other, with the distance between them gradually increasing. Finally, both the first arc-shaped plates 101 and the second arc-shaped plate 102 enter... Figure 6 In the first state shown, both the first arc plate 101 and the second arc plate 102 are in contact with the inner wall of the inner rubber tube, and the first arc plate 101 and the second arc plate 102 together provide internal support for the inner rubber tube. When the first arc plate 101 and the second arc plate 102 rotate, they will drive the inner rubber tube sleeved on them to rotate synchronously, so as to realize the winding of steel wire on the inner rubber tube. After the steel wire is wound, the two second arc plates 102 first approach each other and separate from the inner rubber tube, and then the two first arc plates 101 approach each other and separate from the inner rubber tube. At this time, the contact area between the inner rubber tube with steel wire and the first arc plate 101 and the second arc plate 102 is small, and the resistance encountered by the operator when removing the inner rubber tube with steel wire horizontally along the length of the rotating shaft assembly 1 is small.

[0043] In summary, during the process of installing and removing the inner rubber tube in this embodiment, there are gaps between the first arc plate 101 and the second arc plate 102 and the inner rubber tube. This means that the frictional force on the inner rubber tube is small, and wrinkles and twists are less likely to occur. It should be noted that the plane on which the end face of the second arc plate 102 faces the first arc plate 101 is parallel to the direction of movement of the second arc plate 102 relative to the first arc plate 101, and perpendicular to the direction of movement of the first arc plate 101 relative to the second arc plate 102.

[0044] like Figure 1 and Figure 3 As shown, the rubber hose wire winding device also includes a base and a horizontally sliding translation platform 2 mounted on the base. The sliding direction of the translation platform 2 is parallel to the length direction of the rotating shaft assembly 1. A horizontal sleeve 3 is fixedly installed on the translation platform 2. The sleeve 3 is coaxial with the first arc plate 101 and the second arc plate 102 in the first state. Several C-shaped frames are evenly fixedly installed on the outer wall of the sleeve 3 along its circumference. A wire reel 4 is rotatably installed on the C-shaped frames. When the operator puts the inner rubber tube onto the rotating shaft assembly 1, and the rotating shaft assembly 1 provides internal support for the inner rubber tube, the operator sequentially fixes the ends of the wire wound on the wire reel 4 to the ends of the inner rubber tube. It is important to ensure that the ends of each steel wire are evenly connected to the inner rubber tube. Then, the rotating shaft assembly 1 drives the inner rubber tube to rotate under external force, and the translation stage 2 drives the sleeve 3 and the steel wire reel 4 to translate under external force. The steel wires on the steel wire reel 4 are continuously released and wrapped around the outer wall of the inner rubber tube. When the translation stage 2 reaches the end of its stroke, the steel wires on the steel wire reel 4 are also almost completely released. After the operator removes the ends of the steel wires on the steel wire reel 4, the inner rubber tube with the steel wires wrapped around it can be removed from the rotating shaft assembly 1. The operator then transfers the inner rubber tube with the steel wires wrapped around it to the next processing device for outer rubber covering and molding. Finally, the two ends of the pipe are cut off to obtain the finished product.

[0045] like Figure 2 , Figure 4 and Figure 5 As shown, the rotating shaft assembly 1 also includes a circular plate 103 coaxial with the sleeve 3. The first arc plate 101 and the second arc plate 102 are both slidably mounted on the surface of the circular plate 103. A mounting shaft 104 coaxial with the circular plate 103 is rotatably mounted on the circular plate 103. A first incomplete gear 105 and a second incomplete gear 106 are fixedly sleeved on the mounting shaft 104. A first rack 107 that meshes with the first incomplete gear 105 is fixedly mounted on the first arc plate 101, and a second rack 108 that meshes with the second incomplete gear 106 is fixedly mounted on the second arc plate 102.

[0046] Specifically, the first arc-shaped plate 101 and the second arc-shaped plate 102 are in Figure 5 The second state shown is towards Figure 6 During the first state transition, the mounting shaft 104 rotates clockwise. The first incomplete gear 105 first engages with the first rack 107, causing the first rack 107 and the first arc plate 101 to move relative to the circular plate 103, and the two first arc plates 101 move away from each other. During this process, the second incomplete gear 106 and the second rack 108 have not yet engaged, that is, the second rack 108 and the second arc plate 102 remain stationary relative to the circular plate 103. Subsequently, the first incomplete gear 105 disengages from the first rack 107, and the second incomplete gear 106 engages with the second rack 108. The first rack 107 and the first arc plate 101 remain stationary relative to the circular plate 103, while the second rack 108 and the second arc plate 102 move relative to the circular plate 103, and the two second arc plates 102 move away from each other.

[0047] Similarly, the first arc-shaped plate 101 and the second arc-shaped plate 102 are in Figure 6 The first state shown is towards Figure 5 During the second state transition shown, the mounting shaft 104 rotates counterclockwise, which causes the two second arc-shaped plates 102 to move closer to each other first, and then the two first arc-shaped plates 101 to move closer to each other. Thus, in this embodiment, the switching of the states of the first arc-shaped plates 101 and the second arc-shaped plates 102 can be achieved simply by driving the mounting shaft 104 to rotate with external force.

[0048] It should be noted that in this embodiment, after the two first arc-shaped plates 101 reach the position of the first state, they do not immediately come to rest relative to the circular plate 103, but continue to move away from each other by a small distance, that is... Figure 7 As shown by d, the distance between the two first arc-shaped plates 101 is slightly greater than the width of the second arc-shaped plate 102. When the first arc-shaped plate 101 enters between the two second arc-shaped plates 102, the first rack 107 and the first incomplete gear 105 will disengage. This ensures that the two second arc-shaped plates 102 can enter between the two first arc-shaped plates 101 as they move away from each other, avoiding the situation where the rebound force of the inner rubber tube causes the two first arc-shaped plates 101 to converge towards the middle, thus interfering with the movement of the second arc-shaped plate 102.

[0049] like Figure 2As shown, the circular plate 103 is rotatably mounted on the base via a bracket; a stop bar 109 is fixedly mounted on the circular plate 103, and a push plate 110 cooperating with the stop bar 109 is fixedly mounted on the mounting shaft 104; during the counterclockwise rotation of the mounting shaft 104 relative to the circular plate 103 under external force, the stop bar 109 and the push plate 110 do not contact each other, and the first arc-shaped plate 101 and the second arc-shaped plate 102 transition from the second state to the first state; simultaneously, the stop bar 109 and the push plate 110 come into contact; next, the bracket... When the mounting shaft 104 continues to rotate counterclockwise under external force, it will drive the circular plate 103, the first arc plate 101 and the second arc plate 102 to rotate synchronously, thereby driving the inner rubber tube to rotate synchronously as well; when the mounting shaft 104 rotates clockwise relative to the circular plate 103 under external force, the stop rod 109 and the push plate 110 separate, the circular plate 103, the first arc plate 101 and the second arc plate 102 no longer rotate, and the first arc plate 101 and the second arc plate 102 switch from the first state back to the second state.

[0050] like Figure 1 As shown, a driven gear ring 5, which rotates synchronously with the mounting shaft 104, is sleeved on the mounting shaft 104. A drive motor is fixedly mounted on the bracket, and the drive motor can rotate in both directions. A drive gear ring 6, which meshes with the driven gear ring 5, is fixedly mounted on the output shaft of the drive motor. A lead screw 7, which passes through the translation stage 2, is rotatably mounted on the base via a bearing bracket. One end of the lead screw 7 is connected to the output shaft of the drive motor via a coupling. The driven gear ring 5 can be axially adjusted relative to the mounting shaft 104 to achieve switching between engagement and disengagement with the drive gear ring 6. When the drive motor drives the drive gear ring 6 to rotate, the lead screw 7 also rotates synchronously, and the lead screw 7 drives the translation stage 2. The translation is performed; at the same time, the drive gear ring 6 will drive the driven gear ring 5 and the mounting shaft 104 to rotate, thereby causing the rotating shaft assembly 1 to switch states and drive the inner rubber tube to rotate; thus, in this embodiment, the three actions of switching the state of the rotating shaft assembly 1, rotating the rotating shaft assembly 1 and translating the translation table 2 are realized by the drive motor as a single drive source, saving design and manufacturing costs; it should be noted that after the steel wire is wound, the operator needs to manually switch the position of the driven gear ring 5 to separate it from the drive gear ring 6, and then manually rotate the driven gear ring 5 to switch the first arc plate 101 and the second arc plate 102 back to the second state.

[0051] like Figure 5 and Figure 6As shown, a first spike 8 is installed on the outer arc surface of the first arc plate 101, and a second spike 9 is installed on the outer arc surface of the second arc plate 102. During the transition from the second state to the first state of the first arc plate 101 and the second arc plate 102, both the first spike 8 and the second spike 9 pierce the inner rubber tube. In the first state, the first spike 8 and the second spike 9 are evenly distributed circumferentially on the first arc plate 101 and the second arc plate 102. The operator can connect the ends of the steel wires to the first spike 8 and the second spike 9, so that the ends of each steel wire can be evenly connected to one end of the inner rubber tube. In addition, the first spike 8 and the second spike 9 passing through the inner rubber tube can also drive the inner rubber tube to rotate synchronously with the first arc plate 101 and the second arc plate 102. In summary, in this embodiment, the first spike 8 and the second spike 9 not only facilitate the operator to evenly connect the ends of the steel wires to the inner rubber tube, but also improve the synchronicity of the rotation of the inner rubber tube with the first arc plate 101 and the second arc plate 102.

[0052] In actual processing, the steel wire on the wire spool 4 is in a taut state, and the traction force of the steel wire will drive the wire spool 4 to rotate. Since the traction force of the steel wire fluctuates very little, but the overall mass of the wire spool 4 decreases continuously as the steel wire is released, the wire spool 4 will rotate faster and faster, which makes it impossible for the steel wire to remain in a taut state and affects the winding effect. Based on this, the following improvements have been made in this embodiment.

[0053] like Figure 3 and Figure 8As shown, the wire reel 4 includes a winding portion 401 and round rod portions 402 located at both ends of the winding portion 401. The round rod portions 402 are rotatably engaged with the ferrule frame, and the round rod portions 402 and the winding portion 401 are detachably connected. A first pulley 10 is fixedly sleeved on the round rod portion 402. A speed limiting shaft 11 parallel to the round rod portion 402 is rotatably mounted on the ferrule frame. A second pulley 12 is fixedly sleeved on the speed limiting shaft 11. The first pulley 10 and the second pulley 12 are connected by a transmission belt. A circular ring 13 is fixedly mounted on the speed limiting shaft 11. A speed limiting block 14 is slidably mounted on the outer circumference of the circular ring 13. A return spring 17 is connected between the speed limiting block 14 and the circular ring 13. A circular housing 15 coaxial with the circular ring 13 is fixedly mounted on the ferrule frame. Rubber blocks 16 are evenly fixed on the inner circumference of the circular shell 15. When the wire disc 4 rotates, the first pulley 10 rotates synchronously. The first pulley 10 drives the second pulley 12 and the speed limiting shaft 11 to rotate synchronously through the transmission belt. When the rotation speed of the wire disc 4 is too fast, the speed of the second pulley 12 and the speed limiting shaft 11 also reaches a certain value. Under the action of centrifugal force, the speed limiting block 14 will overcome the action of the return spring 17 and move towards the circular shell 15. The speed limiting block 14 will continuously contact the rubber blocks 16. The rubber blocks 16 play a blocking role on the speed limiting block 14, thereby slowing down the rotation speed of the second pulley 12 and the speed limiting shaft 11. The rotation speed of the wire disc 4 also slows down synchronously. In this way, it is ensured that the rotation of the wire disc 4 will not exceed the speed limit and the wire can be kept taut.

[0054] Example 2

[0055] like Figure 9 and Figure 10 As shown, in this embodiment, the first spike 8 and the second spike 9 are respectively provided with a first through groove 801 and a second through groove 901; the tip of the first spike 8 is provided with a cut that connects to the first through groove 801, and the tip of the second spike 9 is provided with a cut that connects to the second through groove 901; the first through groove 801 and the second through groove 901 are both gourd-shaped, narrow in the middle and wide at both ends; and the end of the first through groove 801 and the second through groove 901 facing the tip is wider.

[0056] Specifically, during the transition of the first arc-shaped plate 101 from the second state to the first state, the first spike 8 pierces the inner rubber tube. The operator holds one end of the steel wire and passes it through the wider end of the first through groove 801 towards the tip. As the first arc-shaped plate 101 continues to transition to the first state, the first spike 8 moves synchronously. The steel wire passes through the narrow area in the middle of the first through groove 801 and enters the end of the first through groove 801 away from the tip. At this time, the first spike 8 clamps the steel wire, and the cut on the first spike 8 is slightly open. Similarly, the second spike 9 also clamps the corresponding steel wire.

[0057] In summary, in this embodiment, the operator only needs to pass the steel wire through the first barb 8 and the second barb 9 to connect the steel wire to one end of the inner rubber tube, and the connection positions of each steel wire are evenly arranged circumferentially. Compared with the prior art where the operator pierces the inner rubber tube and then ties a knot at the end, the difficulty of operation is greatly reduced.

[0058] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
