Description

Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a tire puncture resistance detection device. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are usually installed on various vehicles or machines. They are usually installed on metal rims, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flexibility resistance, as well as low rolling resistance and heat generation.

[0003] During the production process of tires, it is necessary to test their puncture resistance. The current common puncture resistance test usually fixes the tire in water, and uses a hydraulic cylinder to drive the puncture needle to move and pierce the tire surface to see if there are bubbles. The puncture resistance of the tire is tested. In this testing method, the tire is usually in a stationary state. In actual use, the tire is usually in a moving state and contacts sharp objects on the ground, resulting in a deviation between the detected puncture resistance of the tire and the puncture resistance of the tire in actual use, resulting in reduced accuracy of the test.
