Description

Technical Field

[0001] This utility model relates to the field of tire bead production technology, specifically a rapid double-sided pressing tire bead machine. Background Technology

[0002] In traditional tire bead manufacturing processes, to ensure a tight and secure bond between the base of the triangular rubber strip and the steel rim, operators typically place the steel rim and pre-cut triangular rubber strip in predetermined positions on a dedicated platform of the bead machine. The pressure device of the bead machine then performs the first pressing operation. After the first pressing, the operator manually rotates the initially pressed steel rim and triangular rubber strip 180 degrees and places them back on the bead machine platform for a second pressing operation. This repeated pressing process is mainly to further compact the base of the rubber strip, ensuring a gapless and secure bond with the steel rim, thereby meeting the structural strength and durability requirements during subsequent tire molding and use.

[0003] However, this manual operation-dependent process has many shortcomings. First, in the flipping process, operators need to frequently bend over, lift, and precisely flip the tire bead assembly 180 degrees. Not only are the actions highly repetitive, but the labor intensity is also high, and long-term operation can easily cause physical fatigue to the operators. Second, since the entire tire bead pressing process needs to go through the relatively cumbersome process of "initial pressing - manual flipping - secondary pressing", the production cycle of a single tire bead is relatively long, resulting in low overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a fast double-sided tire bead pressing machine to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid double-sided tire bead pressing machine, comprising a worktable, a cylinder, a tensioning wheel, a servo motor, and a side positioning arm. The cylinder is connected directly below the worktable, and a control box is positioned directly above the worktable. The output end of the cylinder is connected to the end of a connecting rod via a bearing. A tensioning wheel is positioned at the top of the connecting rod. An adjustment mechanism is provided on one side of the worktable. When the adjustment mechanism drives a drive gear to rotate, the drive gear engages with the bottom of the side positioning arm. The fixed arc-shaped rack at one end forms a meshing engagement, thereby driving the side positioning arm to rotate around a preset axis inside the equipment housing. Through this rotation adjustment, the relative angle between the side positioning arm and the electric cylinder installed on it can be adjusted synchronously, ultimately achieving precise control over the force applied when the pressure roller presses into the tire bead assembly. A rotating mechanism is provided below the worktable. The servo motor meshes with the driven gear through the second driving gear. The small-diameter second driving gear meshes with the large-diameter driven gear to control the rotation speed of the driving wheel.

[0006] As a preferred technical solution, the distance adjustment mechanism includes an electric cylinder one, an electric cylinder two, an equipment housing, a side positioning arm, a pressure roller, an arc-shaped rack, and a drive gear one. The electric cylinder one is located directly above the equipment housing, and the electric cylinder two is located directly below the equipment housing. The outer sides of both the electric cylinder one and the electric cylinder two are connected to the side positioning arm, which is symmetrically arranged on the upper and lower sides of the equipment housing. The pressure roller is installed on the output ends of the electric cylinder one and the electric cylinder two respectively. The bottom end of the side positioning arm is connected to the arc-shaped rack, and a drive gear one is provided on one side of the arc-shaped rack. The drive gear one is located inside the equipment housing.

[0007] As a preferred technical solution, a side positioning arm is movably connected inside the equipment housing via a rotating shaft, and an arc-shaped rack is fixedly provided at the bottom end of the side positioning arm.

[0008] As a preferred technical solution, the inside of the equipment housing is movably connected to a side positioning arm and bolted to one side of the electric cylinder via a rotating shaft.

[0009] As a preferred technical solution, the rotating mechanism includes a drive wheel, a servo motor, a drive shaft, a driven gear, and a second drive gear. The drive wheel is positioned directly above the worktable. The servo motor is bolted to the inside of the worktable. The output end of the servo motor is connected to the bottom end of the drive shaft via a coupling. A driven gear is spaced at the outer side of the drive shaft. A driven gear is meshed with one side of the second drive gear. The driven gear is positioned directly below the worktable.

[0010] As a preferred technical solution, the bottom end of the drive wheel is fixedly connected to a drive shaft, and the drive shaft and the inner end of the driven gear are circumferentially fixed keyed together by a flat key or spline structure.

[0011] As a preferred technical solution, the output end of the cylinder is symmetrically connected to two sets of connecting rods via bearings, and tensioning wheels are fixedly installed at the top ends of the two sets of connecting rods, with the tensioning wheels being arranged parallel to the drive wheel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When the adjustment mechanism drives the first drive gear to rotate, the first drive gear meshes with the arc-shaped rack fixed at the bottom of the side positioning arm. Through this rotation adjustment, the relative angle between the side positioning arm and the electric cylinder installed on it can be adjusted synchronously, so as to achieve precise control of the force when the pressure roller presses into the tire bead assembly, and ensure the tightness of the fit between the root of the rubber strip and the steel ring and the uniformity of the force during the pressing process.

[0014] 2. This utility model uses a rotating mechanism to convert the high speed output of the servo motor into low speed, high torque rotational power through the deceleration meshing of a small-diameter driving gear and a large-diameter driven gear. The central shaft of the driven gear is fixedly connected to the driving wheel, thereby using this deceleration transmission structure to precisely control the rotational speed of the driving wheel, ensuring that the worktable drives the tire bead assembly to rotate smoothly, accurately, and at a controllable speed during the pressing process, effectively improving the consistency and operational safety of the pressing process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1 and Figure 2 As shown, this utility model provides the following technical solution: a rapid double-sided tire bead pressing machine, including a worktable 1, a cylinder 2, a tensioning wheel 5, a servo motor 11, and a side positioning arm 16. The worktable 1 has the cylinder 2 connected directly below it, and a control box 3 positioned directly above it. The output end of the cylinder 2 is connected to the tail end of a connecting rod 4 via a bearing. The top end of the connecting rod 4 is equipped with a tensioning wheel 5. A distance adjustment mechanism 7 is provided on one side of the worktable 1. When the distance adjustment mechanism 7 drives a drive gear 18 to rotate, the drive gear 18 and the bottom end of the side positioning arm 16... The fixed arc-shaped rack 17 forms a meshing engagement, thereby driving the side positioning arm 16 to rotate around a preset axis inside the equipment housing 14. Through this rotation adjustment, the relative angle between the side positioning arm 16 and the electric cylinder 9 installed on it can be adjusted synchronously, ultimately achieving precise control of the force applied when the pressure roller 15 presses into the tire bead assembly. A rotating mechanism 8 is provided below the worktable 1. The servo motor 11 meshes with the driven gear 13 through the driving gear 19. The small-diameter driving gear 19 meshes with the large-diameter driven gear 13 to control the rotation speed of the driving wheel 6.

[0022] Among them, the rotating mechanism 8 adopts a reduction structure in which a small-diameter active gear 19 meshes with a large-diameter driven gear 13, which converts the high speed of the servo motor 11 into a low speed and high torque output, so that the flipping action of the worktable 1 is smooth and controllable with little impact, avoiding rubber strip deviation, steel ring deformation or equipment wear caused by high-speed flipping, and extending the service life of the equipment.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, the adjusting mechanism 7 includes an electric cylinder 9, an electric cylinder 10, an equipment housing 14, side positioning arms 16, pressure rollers 15, an arc-shaped rack 17, and a drive gear 18. The electric cylinder 9 is positioned directly above the equipment housing 14, and the electric cylinder 10 is positioned directly below the equipment housing 14. Side positioning arms 16 are connected to the outer sides of both the electric cylinder 9 and the electric cylinder 10. The side positioning arms 16 are symmetrically arranged on the upper and lower sides of the equipment housing 14. The pressure rollers 15 are respectively mounted on the electric cylinder 9. The side positioning arm 16 is connected to the output end of the electric cylinder 10. The bottom end of the side positioning arm 16 is connected to an arc-shaped rack 17. A drive gear 18 is provided on one side of the arc-shaped rack 17. The drive gear 18 is provided inside the equipment housing 14. The side positioning arm 16 is movably connected to the inside of the equipment housing 14 through a rotating shaft. The bottom end of the side positioning arm 16 is fixedly provided with an arc-shaped rack 17. The side positioning arm 16 is bolted to one side of the electric cylinder 9 through a rotating shaft inside the equipment housing 14.

[0024] The rotating mechanism 8 driven by the servo motor 11 rotates the active wheel 6, driven gear 13, and active gear 19. This, combined with the adjusting mechanism 7, allows for synchronous or stepwise pressing of the upper and lower sides of the tire rim. No manual intervention or flipping is required; a single positioning operation can achieve a tight fit between both sides of the tire bead assembly. The extension and retraction of the electric cylinders 9 and 10 can be digitally adjusted. The pressure is adaptively adjusted according to different specifications of tire rims and rubber strips to avoid damage to the rubber strips due to overpressure or poor fit due to underpressure, thus improving process adaptability.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rotating mechanism 8 includes a drive wheel 6, a servo motor 11, a drive shaft 12, a driven gear 13, and a second drive gear 19. The drive wheel 6 is positioned directly above the worktable 1. The servo motor 11 is bolted to the inside of the worktable 1. The output end of the servo motor 11 is connected to the bottom end of the drive shaft 12 via a coupling. The driven gear 13 is spaced apart on the outer side of the drive shaft 12. The driven gear 13 is meshed with one side of the second drive gear 19. The driven gear 13 is positioned directly below the worktable 1. The bottom end of the drive wheel 6 is fixedly connected to the drive shaft 12. The drive shaft 12 and the inner end of the driven gear 13 are circumferentially fixed via a flat key or spline structure. The output end of the cylinder 2 is symmetrically connected to two sets of connecting rods 4 via bearings. Tensioning wheels 5 are fixedly installed at the top ends of the two sets of connecting rods 4, and the tensioning wheels 5 are parallel to the drive wheel 6.

[0026] Among them, the adjusting mechanism 7 can change the pressing angle and force of the pressure roller 15 by adjusting the drive gear 18 and other components, and the rotating mechanism 8 can also adjust the state of the worktable 1. Therefore, the equipment can adapt to the production needs of steel rings and triangular rubber strips of different specifications and has a certain degree of versatility and flexibility.

[0027] The working principle of this utility model is as follows:

[0028] The operator places the steel ring and triangular rubber strip on the workbench 1 according to the process requirements. The workbench 1 is a load-bearing platform with a control box 3 on top to coordinate the action of each component. Electric cylinder 9 and electric cylinder 10 are respectively installed on the upper and lower sides of the equipment box 14. Their output ends are connected to the pressure roller 15, which directly contacts the tire bead assembly to apply pressure. The adjustment mechanism 7 is driven by the meshing of the arc rack 17 at the bottom of the side positioning arm 16 through the drive gear 18. The side positioning arm 16 is movably connected to the equipment box 14 through the rotating shaft, driving the side positioning arm 16 to rotate around the preset axis, and synchronously adjusting the angle of electric cylinder 9 or electric cylinder 10 and the pressing direction of the pressure roller 15.

[0029] The telescopic movements of electric cylinder 9 and electric cylinder 10 can precisely control the pressing force of the pressure roller 15 on the tire bead assembly, ensuring that the triangular rubber strip and the steel ring are initially attached and fixed in position. The cylinder 2 is located directly below the worktable 1 and drives the connecting rod 4 to achieve rotational freedom through bearing connection, driving the top tensioning wheel 5 and the active wheel 6 to be raised and lowered in parallel. The two sets of symmetrically distributed tensioning wheels 5 provide auxiliary support and tension balance for the tire bead assembly from both sides.

[0030] The control box 3 initiates the initial pressing command. The worktable 1 maintains its current posture. The worktable 1 is fixed in position through the connection between the drive wheel 6 and the driven gear 13. At this time, the pressure roller 15 applies pressure to the tire bead assembly. The electric cylinder 1 9 drives the pressure roller 15 to press down the rubber strip on the upper surface of the steel ring. At the same time, the electric cylinder 2 10 drives another pressure roller 15 to press up the rubber strip on the lower surface of the steel ring. The pressure of the pressure roller 15 makes the rubber strip fully adhere to and compact the surface of the steel ring. The steel ring leaves the workstation with the conveying component and enters the next process.

[0031] After the initial pressing is completed, the servo motor 11 is installed inside the worktable 1 and starts. It drives the drive shaft 12 to rotate through the coupling. The drive shaft 12 is fixedly connected to the bottom end of the drive wheel 6 and is circumferentially fixed to the inner end of the driven gear 13 through a flat key / spline structure. The driven gear 13 meshes with the second drive gear 19. The second drive gear 19 is a small diameter gear and the driven gear 13 is a large diameter gear, forming a reduction transmission structure. The small diameter drive gear 19 drives the large diameter driven gear 13 to rotate at a low speed, converting the high speed of the servo motor 11 into a low speed and high torque output. The rotation of the driven gear 13 drives the drive wheel 6 to rotate synchronously through the drive shaft 12.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
