Description

Technical Field

[0001] This utility model relates to the field of tire cutting technology, and in particular to a tire sidewall cutting clamp for waste tires. Background Technology

[0002] In the process of recycling and reusing waste tires, cutting the inner sidewall of the tire in a ring is a common processing procedure. When cutting the tire, it is necessary to fix the tire to ensure the cutting effect. At present, the commonly used tire fixing method is "center radial inner support", which means that multiple telescopic rods radiate outward from the center of the inner side of the tire, and the telescopic rods are used to press against the inner wall of the tire to achieve fixation.

[0003] However, when the cutting blade contacts the tire and makes a circular cut, the friction between the blade and the tire carcass rubber and internal ply layers generates a continuous tangential force. Since traditional clamps only contact the inner wall of the tire through the inner telescopic rod, the contact area is limited to a small area at the end of the telescopic rod. Furthermore, the friction force generated by the radial clamping force of the telescopic rod is used to counteract the tangential force. When the tangential force exceeds this friction threshold, the tire will passively rotate with the blade. This is especially true for some thicker tires, which are more likely to rotate synchronously with the cutting blade during cutting, affecting the cutting quality.

[0004] Based on the above situation, it is necessary to design a waste tire sidewall cutting fixture to solve the above problems. Utility Model Content

[0005] This utility model provides a waste tire sidewall cutting clamp to solve the problems in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution: A waste tire sidewall cutting clamp includes a support base, an inner clamping mechanism, an outer clamping mechanism, and a control unit. The inner clamping mechanism is located within the support base and includes multiple sets of inner telescopic members. The inner telescopic members can extend and retract radially outward along the tire to abut against the inner wall of the tire. The outer clamping mechanism is located within the support base and includes multiple sets of outer telescopic members. The outer telescopic members are arranged one-to-one with the inner telescopic members. The outer telescopic members can extend and retract radially inward along the tire to abut against the outer wall of the tire. The clamp is configured to control the movement of the inner telescopic members and the corresponding outer telescopic members. When the inner telescopic member extends outward to abut against the inner wall of the tire, the corresponding outer telescopic member is driven to extend inward and abut against the outer wall of the tire, thereby forming a radially opposing clamping grip on the tire.

[0007] Preferably, both the inner and outer telescopic components include a telescopic rod, a sliding sleeve slidably fitted onto the movable end of the telescopic rod, and an elastic component disposed between the telescopic rod and the sliding sleeve.

[0008] Preferably, the sliding sleeve is provided with an abutment portion, which is arc-shaped.

[0009] Preferably, the control unit includes a controller and a plurality of pressure sensors electrically connected to the controller, the pressure sensors being located at the movable end of the telescopic rod.

[0010] Preferably, a clamping space for placing a tire is formed between the inner clamping mechanism and the outer clamping mechanism, and a plurality of ball bearings are provided in the clamping space.

[0011] Preferably, the inner and outer telescopic components are distributed at equal angles along the circumference, and the included angles of two adjacent sets of inner telescopic components and two adjacent sets of outer telescopic components are equal, so as to form a balanced radial clamping force.

[0012] The beneficial effects of this utility model are: by controlling the inner clamping mechanism to extend and retract outward to press against the inner wall of the tire, while the outer clamping mechanism extends and retracts inward to press against the outer wall of the tire, the tire is clamped against each other, which enhances the stability of the tire during cutting and improves the cutting quality.

Detailed Implementation

[0016] 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.

[0017] Reference Figures 1-5 As shown, the waste tire sidewall cutting clamp includes a support base 1. Inside the support base 1 are an inner clamping mechanism and an outer clamping mechanism. The inner clamping mechanism includes multiple sets of inner telescopic members 2, and the outer clamping mechanism includes multiple sets of outer telescopic members 3. The inner telescopic members 2 and outer telescopic members 3 are arranged in a one-to-one correspondence. In use, the tire is placed on the support base 1 and positioned between the inner and outer clamping mechanisms. At this time, by activating the control unit 4, the control unit 4 controls the movement of the inner telescopic members 2 and the corresponding outer telescopic members 3, causing the inner telescopic members... 2. The inner telescopic component 2 extends outward along the radial direction of the tire to press against the inner wall of the tire. When the inner telescopic component 2 presses against the inner wall of the tire, the control unit 4 drives the corresponding outer telescopic component 3 to extend inward and press against the outer wall of the tire. At this time, the inner clamping mechanism and the outer clamping mechanism form a radially opposing clamping of the tire, which can firmly lock the tire in the preset position. At the same time, this bidirectional force can also counteract the vibration or impact force generated during the cutting process, prevent the tire from shifting or rotating, ensure the cutting path is accurate, reduce the problem of the tire sidewall rotating synchronously with the cutting blade during the cutting process, and improve the cutting quality.

[0018] Reference Figure 5 As shown, both the inner telescopic member 2 and the outer telescopic member 3 include a telescopic rod 5, a sliding sleeve 6 located at the movable end of the telescopic rod 5, and an elastic element 7 located between the telescopic rod 5 and the sliding sleeve 6. The telescopic rod 5 can be a hydraulic telescopic rod, etc., and the elastic element 7 can be a spring, tension spring, etc. When the inner telescopic member 2 moves outward and abuts against the inner wall of the tire, the control unit 4 activates the telescopic rod 5 to perform telescopic movement. When it contacts the tire, the sliding sleeve 6 first contacts the tire surface, and as the telescopic rod 5 gradually presses against it, the elastic element 7 is deformed. At the same time, the sliding sleeve 6 slides on the outer wall of the telescopic rod 5. For old tires that are deformed, unevenly worn, or partially damaged, when the clamping force is applied to the uneven surface of the tire, the sliding sleeve 6 can conform to the tire surface shape, avoiding mechanical damage to the tire and damage to the tire due to rigid contact.

[0019] Among them, such as Figure 3 As shown, the sliding sleeve 6 is provided with an abutment part 8, which is arc-shaped. The sidewall of the waste tire itself is an arc-shaped curved surface. The arc-shaped abutment part 8 can naturally fit with the curved surface of the tire. Compared with a flat or angular abutment part 8, it can increase the contact area and reduce the slippage problem caused by the small contact point, ensuring that the part to be cut on the sidewall and the position of the tool are relatively fixed during the cutting process.

[0020] Reference Figure 5As shown, the control unit 4 further includes a controller 41 and multiple pressure sensors 42 electrically connected to the controller 41. The pressure sensors 42 are located at the movable end of the telescopic rod 5. When the waste tire is placed randomly on the support base 1, the position of the tire may be offset. At this time, the telescopic rod 5 on the inner clamping mechanism moves. During the process, the sliding sleeve 6 contacts the pressure sensor 42. When all the pressure sensors 42 on the inner clamping mechanism detect the pressure signal, the tire is then adjusted to the middle position of the support base 1 by the inner clamping mechanism. Then, the pressure sensor 42 transmits the signal to the controller 41. The controller 41 controls the movement of the outer clamping mechanism to clamp and fix the tire synchronously with the inner clamping mechanism, thereby achieving automatic adjustment.

[0021] Reference Figures 1-3 As shown, furthermore, during the process described above, when the inner clamping mechanism adjusts the position of the tire, the tire may move on the support seat 1. In order to reduce the friction between the tire and the support seat 1, a clamping space for placing the tire is formed between the inner clamping mechanism and the outer clamping mechanism. Multiple balls 9 are provided in the clamping space. As the tire moves, the balls 9 will roll, reducing the friction between the tire and the support seat 1.

[0022] Reference Figures 1-3 As shown, after clamping and fixing the tire, cutting begins. The position of the cutting blade can be adjusted by the telescopic structure. To further improve the stability of the cutting, the inner telescopic component 2 and the outer telescopic component 3 are distributed at equal angles along the circumference. The included angles of two adjacent sets of inner telescopic components 2 and two adjacent sets of outer telescopic components 3 are equal to form a balanced radial clamping force. The sidewall of the waste tire may have structurally weak areas due to aging and damage. If the telescopic components are not distributed evenly, local stress concentration may cause the sidewall to dent, tear, or even shift. The telescopic components distributed at equal angles can form a symmetrical constraint force to offset the influence of tangential force from all directions, keeping the tire axially fixed during cutting.

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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
