A rubber wear resistance testing device and testing method thereof

Abstract

The invention belongs to the technical field of rubber detection, in particular to a rubber wear resistance detection device and a detection method thereof, aiming at the phenomenon that the sample is often easily worn through during the friction process, so that the wear of the detection equipment affects the detection efficiency. Secondly, during the detection process When the sample is subjected to friction, it is prone to uneven force and offset phenomenon. The following scheme is proposed, including the shell, the top of the shell is hinged with a cover, and the inside of the shell is installed with multiple bearings. The transmission roller is fixedly installed with a stepping motor connected to the transmission roller in the inside of the housing, and a moving belt is sleeved on the outside of the rotating roller. In the feeding stage of the present invention, the assembly for fixing the rubber sample can be lifted by the electric push rod to separate it from the abrasive cloth belt, which can effectively avoid the influence on the abrasive cloth belt during the feeding process, and when the rotational speed of the abrasive cloth belt is constant during the detection process , and then lower the assembly with the rubber sample fixed, so that the sample is in contact with the abrasive cloth belt, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of rubber detection, in particular to a rubber wear resistance detection device and a detection method thereof. Background technique [0002] The rubber industry is one of the important basic industries of the national economy. It not only provides daily and medical light industrial rubber products that are indispensable for people’s daily life, but also provides various rubber production equipment or rubber parts for mining, transportation, construction, machinery, electronics and other heavy industries and emerging industries. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer. [0003] Rubber is divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other pl...

AI Technical Summary

Problems solved by technology

Rubber products are widely used in all aspects of industry or life. There are strict quality requirements for rubber materials and products, such as tensile strength, elastic modulus, elongation, aging resistance, etc. When testing the wear resistance of rubber, cut and fix The size of the sample is rubbed against the surface of the rotating grinding wheel roller, and its wear resistance can be detected by comparing the weight before and after. It is easy to cause the wear-through phenomenon of the sample, so that the wear of the detection equipment affects the efficiency of the detection. Secondly, when the sample is rubbed during the detection process, it is prone to uneven force and offset phenomenon, which affects the accuracy of the result.
