Novel rubber abrasion test machine

Abstract

The invention provides a novel rubber abrasion test machine for detecting abrasion performance of rubber. The novel rubber abrasion machine adopts a vertical structure and mainly comprises a base, a chassis, a heat transfer rotating hub, a sand belt, a belt pulley, a friction anvil, a shaft and machine system and a corresponding cooperation device, wherein the cooperation device comprises an aging test system, a chassis internal drying apparatus, a brake system, a control panel, a rapping apparatus, a damping apparatus, a circuit and a temperature control assembly. A rubber wheel test sample is fixed on the heat transfer rotating hub, and the test temperature is controlled by virtue of a refrigerating and heating system and the temperature control assembly; the shaft and machine system control test friction positive pressure and a friction deflection angle; the rapping apparatus realizes silt-free chippings removal; and the damping apparatus, the aging test apparatus, the chassis internal drying apparatus and the brake system are used for more accurately simulating and testing the aging abrasion and the abrasion of the rubber under an actual brake condition.

Description

technical field [0001] The invention relates to a material testing device, in particular to a fully automatic abrasion machine for detecting the abrasion parameters of rubber materials. Background technique [0002] The rubber abrasion tester is a kind of equipment widely used in the rubber industry to test the abrasion performance of rubber materials. Mostly, the rubber sample is rubbed, and the wear performance of the rubber is evaluated by measuring the weight loss of the rubber sample before and after the experiment. [0003] When used as a tire, due to the physical and chemical properties of the rubber itself, heat will be generated inside the rubber in the case of reciprocating deformation. The heat generated inside the rubber will change various properties of the rubber, including the wear characteristics of the rubber. From this, it can be concluded that the rubber grinding experiment must take into account the internal heat generation of rubber, but most of the exi...

AI Technical Summary

Problems solved by technology

When there is too much glue on the friction object, it will affect the measurement of the wear parameters of the rubber sample.

[0005] Most of the current abrasion testing machines have relatively single performance and cumbersome experimental process. Some high-end products have relatively complete functions, but the price is relatively high, and the simulation of the key rubber internal heat generation is not in place.
