Problems solved by technology

After the small loader has been used for a long time on complex and rough terrain, the tread pattern will be worn out, and the adhesion between the tire and the road surface will be reduced, which will affect the traction and passing performance of the loader and increase fuel consumption. The impact performance is reduced, which weakens the protective effect of the tire tread on the carcass, and easily causes the puncture and explosion of the tire cord layer. Therefore, when the tread wears to a certain limit, the tire should be retreaded in time; ordinary tire grinding on the market When the equipment is grinding, the retreaded tire tread often has inconsistent dimensions, and the tread unevenness that deviates from the balanced shape appears on the cross-sectional structure, which makes it difficult to remove the tire from the grinding equipment after grinding

Embodiment 1

[0023] Such as Figure 1 to Figure 2As shown, the tire retreading method of the present invention is to place the tire to be retreaded on the expansion clamping part, start the first cylinder 8, the output end of the first cylinder 8 retracts, and drives the connecting rod 9 to the DC motor 4 One side moves, at this time the slider 10 is in contact with the expansion clamping part, and the volume of the expansion clamping part increases under the action of the front top of the slider 10, and the outer wall of the expansion clamping part contacts the middle part of the tire, thereby realizing Clamping of the tire; when the tire is clamped stably, turn the DC motor 4, and the pinion 6 on the output end of the DC motor 4 cooperates with the large gear 5 at the end of the sleeve 2, so that the expansion clamping part drives the tire in the L-shaped Rotate and move on support base 1, facilitate retreading cutter 18 to process tire, when processing is finished, DC motor 4 stops rota...

Embodiment 2

[0026] Such as Figure 1 to Figure 2 As shown, this embodiment is based on Embodiment 1, the expansion clamping part includes an elastic expansion cover 7, the small diameter end of the elastic expansion cover 7 is connected to the sleeve 2, and the elastic expansion cover 7 A claw 11 is installed on the large diameter end, and the upper end surface of the claw 11 is arc-shaped. When clamping the tire, the elastic expansion cover 7 passes through the inner side of the bead, and the claws 11 are in contact with the inner wall of the bead. stability, and when the sleeve 2 rotates, it avoids slipping between the inner wall of the bead and the claw 11, and further reduces the unevenness when cutting the tread.

Embodiment 3

[0028] Such as figure 2 As shown, on the basis of Embodiment 1, the present embodiment includes a cylindrical body 26 and a rotating shaft 21, the rotating shaft 21 is arranged in the cylindrical body 26, the two ends of the rotating shaft 21 protrude from the two ends of the cylindrical body 26, and the rotating shaft 21 One end is rotatably connected to the tool holder 17, the other end of the rotating shaft 21 is connected to the bevel gear 20, and a plurality of arc-shaped blades 24 are uniformly arranged on the rotating shaft 21, and the arc-shaped blades 24 are hinged to the rotating shaft 21. 26 is provided with an opening corresponding to the arc-shaped blade 24, and the arc-shaped blade 24 runs through the opening. A block 27 is arranged on the inner wall of the cylinder 26. One side of the block 27 is an arc-shaped concave surface, and the arc-shaped concave surface and the arc-shaped The arc outer sides of the blades 24 are connected by a spring 25 . Rotating shaf...

Abstract

The invention discloses a method for retreading of a loader tyre. Through changing the volume of an expansion clamping part, the method realizes tyre clamping fixation. The end face of the expansion clamping part closely contacts with the inside of tyre bead so that the fixing effect of the tyre in machining processes such as cutting are guaranteed and retreated tyre surface parts having improper shapes and sizes are reduced. When lifting and dropping a cutting tool, a raised part mounted on an output end of a second air cylinder is meshed with a trapezoidal groove of a support bar so that the cutting tool can move in the horizontal direction and the contact area between the cutting tool and the tyre surface can be timely adjusted and thus tyre surface local excessive-polishing is avoided.

Description

technical field [0001] The invention relates to a grinding tool, in particular to a method for retreading a tire of a loader. Background technique [0002] Tire retreading is a positive way to recycle waste tires, and it is the extension and processing and reuse of the tire industry. It is of great significance to promote resource conservation and comprehensive utilization, and promote the transformation of economic growth mode and sustainable development. As far as its prospects are concerned, the retreading of waste tires is an indispensable industry in the automobile industry and transportation just like the tire industry. [0003] Tire retreading refers to a process in which old tires are partially repaired and reapplied with rich tread rubber, and then vulcanized to restore their use value. Tire retreading and utilization refers to the reuse of old tires with repair value after retreading and repairing. After processing and crushing waste tires that cannot be retreaded...
