Tool for detecting aging of tire rubber piece with low rolling resistance

Abstract

The invention relates to a tool for detecting aging of a tire rubber piece with low rolling resistance. The tool comprises a bracket, elastic mechanisms and a stretching mechanism, wherein the bracket jointly consists of permanent seats which are transversely arranged and guide rods which are longitudinally arranged, wherein two permanent seats are arranged and a plurality of guide rods are sequentially distributed between the two permanent seats along the long axis directions of the permanent seats; through holes through which the guide rods pass are formed in the two permanent seats; the guide rods are movably connected with the elastic mechanism A which can be driven by the stretching mechanism to reciprocate along the long axis directions of the permanent seats, and the elastic mechanism B is fixedly connected to one of the permanent seats. The tool provided by the invention has the advantages that by virtue of the device, the rubber piece is compressed by using a bolt and meanwhile, the fixing mode of the bolt and a nut is stronger than a clamping force of a clip, so that the rubber piece can be better fixed; meanwhile, the stretching length of the rubber piece is directly adjusted by virtue of the stretching mechanism during stretching, so that the tool is very convenient.

Description

technical field [0001] The invention relates to a detection tool, in particular to a low rolling resistance tire film aging detection tool. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, which shows the ability of tires to consume r...

However, during the whole process, the staff found that when the clips were used to clamp the film, due to the insufficient pre-tightening force of the clips, the film loosened during the aging process, resulting in the inability to accurately measure the rebound distance
