Description

Agricultural tire bladder vulcanizing machine Technical Field

[0001] This utility model relates to the field of vulcanizing machine technology, specifically to an agricultural tire bladder vulcanizing machine. Background Technology

[0002] A vulcanizing bladder is a hollow, thin-walled rubber product in a tire vulcanizing machine. It is used to fill the inner cavity of the tire blank to be vulcanized and then introduce a heating medium to work with the vulcanizing machine for shaping and vulcanization.

[0003] The vulcanization process for tires on most motorcycles, electric vehicles, and small agricultural machinery generally employs two main structural methods:

[0004] 1. The plunger cylinder is installed at the bottom of the machine. When working, the cylinder plunger moves from bottom to top. Due to the large stroke (about 1400mm), the movement is slow and the efficiency is low. Moreover, the installation is troublesome. Users need to dig a foundation to install the cylinder.

[0005] 2. A single piston cylinder is installed on the top of the equipment. When working, the cylinder piston moves from top to bottom. The disadvantage is that the stroke is large (about 1400mm), the movement is slow, the efficiency is low, and there are extremely high operational risks during transportation and on-site installation. Summary of the Invention

[0006] This invention addresses the problems of slow cylinder movement and cumbersome installation in existing tire vulcanization processes on mechanical equipment by providing an agricultural tire bladder vulcanizing machine.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an agricultural tire bladder vulcanizing machine, including a frame with a frame-type pressure-bearing structure; a hydraulic station located at the rear of the frame; and multiple sets of stamping components, which, from bottom to top, include the following in a vertical direction:

[0008] Ring seat, fixed to the bottom of the frame;

[0009] The middle platform is slidably connected to the slide rails on the inner side of the frame via sliders on both sides, and guide rods are provided on both sides of the middle platform;

[0010] The upper platform is slidably connected to the slide rails on the inner side of the frame via sliders on both sides, and slidably connected to the guide rods via guide blocks on both sides. The top of the guide rods is provided with limit bolts.

[0011] The main hydraulic cylinder's longitudinal displacement is adjusted via a push-pull assembly on the top of the frame;

[0012] Side-pull hydraulic cylinders are symmetrically arranged on the top of the frame, and their piston rods are connected to the upper platform to drive the upper platform to lift and lower.

[0013] The adjustment component, located at the center of the upper platform, is used to dynamically adjust the stamping stroke of the main hydraulic cylinder.

[0014] This utility model further describes that the push-pull assembly includes:

[0015] A top platform is fixed to the top of the frame, and a sliding groove is provided at its bottom. The top platform extends toward the rear of the frame.

[0016] The movable plate is slidably disposed in the slide groove and is fixedly connected to the main oil cylinder;

[0017] A push-pull cylinder is located on the lower side of the outer end of the top platform, and its piston rod is connected to the moving plate;

[0018] A through hole extends through the front side of the top platform, allowing the adjustment components to pass through.

[0019] This utility model further describes that the adjustment component includes:

[0020] Adjust the uprights and fix them vertically to the center of the upper platform;

[0021] The adjusting screw passes through the adjusting column and achieves lifting and lowering adjustment through the threaded pair.

[0022] The pressure plate is fixed to the upper end of the adjusting screw and can abut against the end of the piston rod of the main oil cylinder.

[0023] The present invention further explains that the surfaces of the middle platform and the ring seat opposite each other, as well as the surfaces of the upper platform and the middle platform opposite each other, are provided with molds for vulcanization; the middle platform and the ring seat are also provided with ejection mechanisms to assist demolding, and the ejection mechanisms are driven by ejection cylinders located on the front and rear sides of the mold.

[0024] The present invention further explains that the center of both the ring seat and the central platform is provided with a coaxially positioned central column, which is used to fix the preformed rubber blank of the tire bladder.

[0025] The present invention further explains that a through hole is provided directly above the through hole on the top of the frame, and the through hole is used for the adjustment component to pass through.

[0026] The advantages of this utility model are: the single main cylinder is modified into a segmented design to improve work efficiency; the stroke of the main cylinder is shortened; the height adjustment mechanism is composed of a column and a lead screw; the height adjustment mechanism can adjust the height according to different molds to shorten the stroke of the cylinder.

[0027] The push-pull assembly of the main cylinder consists of a push-pull cylinder and a top platform. When the middle platform descends to the designated position, the push-pull cylinder is activated to push the main cylinder to the center position of the frame. The quick-pull cylinder can realize the rapid lifting and lowering of the upper platform, improving efficiency.

[0028] By adjusting the structure, the lifting time of the vulcanizing machine is shortened. Furthermore, the design with the main oil cylinder on top eliminates the need for users to dig a foundation, allowing the machine to be placed directly on a level surface. This replaces the traditional design with the oil cylinder on the bottom, which required workers to stand on an additional raised platform to pick up and place products, thus reducing the workers' operating height.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings.

[0036] Referring to Figures 1-5, the agricultural tire bladder vulcanizing machine includes a frame 1, a hydraulic station 2, multiple sets of stamping components 3, a main oil cylinder 34, a side pull oil cylinder 35, an adjustment component 5, and a push-pull component 4.

[0037] The frame 1 is a frame-type pressure-bearing structure welded from high-strength steel, and the inner side is equipped with a vertical slide rail 103.

[0038] The hydraulic station 2 is located at the rear of the frame 1 and is connected to the main oil cylinder 34, the side pull oil cylinder 35 and the ejection cylinder 61 through pipelines.

[0039] The stamping assembly 3 is divided into three layers from bottom to top along the vertical direction:

[0040] Ring seat 31: Fixed to the bottom of frame 1, with a central column 7 for coaxial positioning at the center.

[0041] The middle platform 32 is slidably connected to the slide rail 103 of the frame 1 via two side sliders 301. Guide rods 320 are provided on both sides, and limit bolts are provided at the top of the guide rods 320. The lower surface of the upper platform 33, the upper and lower surfaces of the middle platform 32, and the upper surface of the ring seat 31 are all equipped with vulcanizing molds. Electric heating elements are embedded in the molds. The middle platform 32 has a central column 7, which is coaxially engaged with the central column 7 of the ring seat 31.

[0042] Upper platform 33: It is slidably connected to slide rail 103 via slider 301, and slidably engaged with guide rod 320 of middle platform 32 via guide block.

[0043] The main hydraulic cylinder 34 achieves longitudinal displacement adjustment through the push-pull assembly 4:

[0044] The push-pull assembly 4 includes a top platform 41, a movable plate 42, and a push-pull cylinder 43. The top platform 41 is fixed to the top of the frame 1, and has a sliding groove at the bottom that extends to the rear of the frame 1. The movable plate 42 is slidably disposed in the sliding groove and is flange-connected to the main cylinder 34. The push-pull cylinder 43 is installed on the lower side of the outer end of the top platform 41, and its piston rod is hinged to the movable plate 42 to drive the main cylinder 34 to move back and forth. The through hole 44 penetrates the front side of the top platform 41, allowing the pressure plate 53 of the adjusting assembly 5 to pass through.

[0045] Adjustment component 5 includes:

[0046] Adjustable column 51: vertically welded to the center of the upper platform 33.

[0047] Adjusting screw 52: It passes through the adjusting column 51 and achieves lifting and lowering adjustment through the threaded joint, and the top is fixed with pressure plate 53.

[0048] Pressure plate 53: It abuts against the end of the piston rod of the main oil cylinder 34. The height of the pressure plate 53 can be changed by rotating the adjusting screw 52, ​​thereby realizing the dynamic adjustment of the stamping stroke of the main oil cylinder 34.

[0049] Both the ring seat 31 and the middle platform 32 have ejection holes on their front and rear sides. The ejection cylinder 61 pushes the vulcanized tire bladder out of the mold through the ejection hole via the ejector rod. The ejection cylinder 61 is independently controlled by the hydraulic station 2 and moves synchronously during demolding to avoid deformation of the bladder.

[0050] In a specific implementation case, the preformed capsule embryo is fitted onto the central column 7 to ensure coaxial positioning; the side pull cylinder 35 drives the upper platform 33 to move downward (at this time, the main cylinder 34 is stopped behind the frame 1), the middle platform 32 presses on the ring seat 31, the guide rod 320 cooperates with the guide block to guide, and the upper platform 33 slides onto the middle platform 32, so that the three-layer mold is closed; the main cylinder 34 is adjusted to the preset position through the push-pull assembly 4, and the push-pull cylinder 43 starts to drive the moving plate 42 to move the main cylinder 34 to the axis of the central column 7. The piston rod of the main cylinder 34 presses down on the pressure plate 53 (the optimal state is that the distance between the piston rod of the main cylinder 34 and the upper plane of the pressure plate 53 is 10mm, at which time the main cylinder 34 can quickly apply pressure), and begins to pressurize the mold, providing vulcanization pressure for the stamping assembly 3; the mold is heated to complete vulcanization.

[0051] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
