Description

Technical Field

[0001] This utility model relates to the field of tire cutting technology, and in particular to a tire wire ring cutter. Background Technology

[0002] In the processes of tire recycling and dismantling, as well as tire manufacturing quality inspection, it is often necessary to cut the tire wire bead. Current tire wire cutting equipment mostly uses a method of placing the tire on a cutter, inserting a roller into the tire to drive the tire to rotate, and cutting blades located on both sides of the tire cutting the tire during the rotation.

[0003] However, in actual use, the tires rely on rollers for support. While the size of the rollers is fixed, tires come in a variety of specifications, and their inner diameters vary significantly. This makes it difficult for the rollers to fit different tire specifications. When the roller diameter is smaller than the tire's inner diameter, it cannot provide effective support and driving force, causing the tire to rotate unsteadily. When the roller diameter is larger than the tire's inner diameter, it cannot be inserted into the tire, and the equipment cannot operate normally.

[0004] Therefore, based on the above situation, we designed a tire wire bead ring cutter to solve the above problems. Utility Model Content

The fixing unit includes multiple fixing members distributed along the circumference of the support column. The multiple fixing members are synchronously adjusted in extension state to form a variable diameter support structure that adapts to different tires. The first driving component is disposed on the base and its movable end is connected to the support column to drive the support column to rotate. The cutting assembly is movably disposed on the base and its position is adjustable to adapt to the wire bead cutting position of tires of different sizes.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] Reference Figures 1-4 As shown, a tire wire bead ring cutter includes a base 1, which provides stable support. A support column 2 is rotatably connected to the base 1. A fixing unit is provided on the support column 2. The fixing unit includes multiple fixing members 3 distributed along the circumference of the support column 2. In use, the support column 2 is passed through the center of the tire, and then the extension states of the multiple fixing members 3 are synchronously adjusted. At this time, the fixing unit forms a variable diameter support structure that adapts to different tires. The extension state of the fixing members 3 is adjusted according to the inner diameter of the tire of different sizes, so that the fixing unit contacts the inner wall of the tire, supports the inner wall of the tire, and fixes the position of the tire.

[0022] After the tire position is fixed, the position of the cutting component 5, which is movable on the base 1, is adjusted to adjust the cutting position according to the tire wire ring of different inner diameters. At this time, the first driving component 4, which can be a motor or the like, is activated on the base 1. Its movable end drives the support column 2 to rotate, thereby driving the fixed unit on the support column 2 and the tire supported and fixed by the fixed unit to rotate. Different positions on the rotating tire continuously contact the cutting component 5, and the cutting component 5 performs a circular cut to obtain a complete wire ring. This process not only increases the stability of the tire during cutting, but also improves the adaptability to tires of different sizes.

[0023] Reference Figures 1-4 As shown, further, the fixing member 3 includes a telescopic member 31 connected to the support column 2 and a support part 32 connected to one end of the telescopic member 31. The telescopic member 31 can be an electric telescopic rod, a hydraulic telescopic rod, or other structures. The telescopic member 31 extends and retracts radially along the support column 2. That is, if the support column 2 is vertically set, the telescopic member 31 extends and retracts horizontally. The synchronous extension and retraction of each telescopic member 31 allows the support part 32 to contact the inner wall of the tire, ensuring that the tire is evenly stressed in all directions. This avoids tire tilting, shifting, or damage caused by excessive local stress due to uneven stress, ensuring that the tire maintains a stable posture during the cutting process and improving cutting accuracy. In order to ensure the synchronous extension and retraction of all telescopic members 31, a controller can be set up to synchronously control all telescopic members 31. The operator only needs to issue a control command through the controller, and all telescopic members 31 can move in coordination, reducing operation steps and the probability of errors.

[0024] The support part 32 is arc-shaped and has multiple anti-slip grooves along its length. The outer surface of the tire is usually arc-shaped, and the arc design of the support part 32 can perfectly fit it, increasing the contact area, dispersing the contact pressure, avoiding local stress concentration that could cause tire damage. The arc-shaped edge can be smoothly transitioned, reducing direct contact between sharp edges and the tire, and lowering the risk of cutting the tire tread. It is especially suitable for processing retreaded tires or high-value special tires. The anti-slip grooves can increase the coefficient of friction between the support part 32 and the tire, effectively preventing the tire from slipping or shifting during the cutting process.

[0025] Reference Figure 3 , Figure 4 As shown, the cutting assembly 5 further includes a telescopic support frame 51 connected to the base 1 and two cutting blades 52 disposed opposite to each other on the telescopic support frame 51. The telescopic support frame 51 can be extended and retracted by an electric telescopic rod, hydraulic telescopic rod, etc., and support plates are set at both ends of it so that the cutting blades 52 are disposed opposite to each other on the two support plates. When in use, the second drive unit 6 on the base 1 is activated, and the cutting assembly 5 is pushed to a suitable position close to the tire. The second drive unit 6 can be an electric telescopic rod, hydraulic telescopic rod, etc. At this time, the tire is located between the two cutting blades 52. Then the telescopic support frame 51 is shortened so that the two cutting blades 52 contact the upper and lower surfaces of the tire respectively, which can improve the flexibility of use.

[0026] Reference Figure 3 , Figure 4 As shown, a stabilizing seat 7 is provided on the inner top surface of the telescopic support frame 51. A pressing roller 8 is rotatably connected inside the stabilizing seat 7. When the cutting blade 52 cuts the tire surface, the tire surface also contacts the pressing roller 8 at the same time. The pressing roller 8 contacts the top surface of the tire. When the telescopic support frame 51 adjusts the clamping force, the pressure is evenly distributed on the tire surface through rolling contact, avoiding tire deformation or damage due to excessive local force.

[0027] Reference Figures 1-3 As shown, further, a receiving plate 9 connected to the base 1 is provided below the fixing unit. Multiple rotating rollers 10 are equidistantly connected to the receiving plate 9 along its circumference. Before use, the tire is placed directly on the receiving plate 9, and its position is relatively fixed, providing a reference for the subsequent clamping of the fixing unit, improving positioning efficiency. When the tire rotates, the multiple rotating rollers 10 evenly support the bottom surface of the tire along the circumference, avoiding tilting caused by single-point force, improving fixing stability and reducing wear caused by contact between the tire surface and the receiving plate 9.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
