Description
Technical Field
The utility model relates to an experimental apparatus of rubber roll wearing and tearing, concretely relates to rubber roll friction and wear test device of variable environment.
Background
In the production of cold-rolled sheets, in order to combine with sheet production lines such as pickling lines, tin plating lines, chrome plating lines, and the like, and to be able to adapt to various severe conditions such as chemical corrosion resistance, aging resistance, heat resistance, oil resistance, and the like, the types of rubber rollers mainly used are Chloroprene Rubber (CR), nitrile rubber (NBR), and chlorosulfonated polyethylene rubber (CSM). For the rubber rollers of the types, the requirements of balanced performances in all aspects, wide adjustable range of hardness, high tensile strength and compressive strength, excellent wear resistance and excellent oil resistance and shock absorption performance are met; some requirements are that the heat resistance is good and the heat-damp environment can work; some of them require good chemical resistance to exert excellent performance in acid-base medium. The rubber rollers are made of high polymer rubber materials, rolling sliding friction is continuously generated in the working process of the rubber rollers, the fatigue performance of the rubber rollers is related to the types of the materials, the high polymer materials have viscoelasticity, and the mechanical properties are dependent on temperature, strain rate and time. The friction of rubber is directly related to the viscoelasticity parameters tan delta and the elastic modulus, the elastic modulus decreases with the increase of temperature, tan delta first increases and then decreases with the increase of temperature (the temperature of an extreme point is lower than 0 ℃), therefore, the friction coefficient first increases and then decreases with the increase of temperature, and the extreme point is related to the extreme point of tan delta and the rate of decrease of the elastic modulus with the increase of temperature. With an increase in temperature, the elastic modulus of the rubber decreases and the wear patch pitch increases. Under the condition of high temperature, the rubber is seriously aged, the tearing strength is reduced, so that the wear rate is obviously increased, and the wear rate is periodically changed in a large range. In dynamic fatigue of rubber materials, the frequency also has a large influence on the fatigue life. As the frequency increases, the spreading rate of the different polymeric materials may decrease, remain constant, or increase. In general, increasing the flattening of dynamic fatigue will result in a decrease in Nf. Because at low frequencies, the sample temperature rise can be thermally balanced with ambient temperature through heat transfer; at high frequency, due to poor heat conductivity of rubber, internal temperature rise cannot be timely transmitted, heat energy accumulation promotes heat aging process and thermal degradation, and Nf is inevitably reduced. Meanwhile, the rubber roller is always under the action of cyclic load, so that the fatigue performance of the rubber material is influenced certainly, wherein the influence factors mainly include the influence of average stress, stress amplitude and loading frequency on the fatigue damage of the material.
Therefore, the abrasion of the rubber roller in the using process is related to various factors, and if the abrasion of the rubber roller in the using process is to be comprehensively simulated, the friction abrasion test of the rubber roller sample needs different conditions of temperature, rotating speed and tension force to carry out the simulation test.
However, the conventional rubber friction wear test device on the market at present is a test device for friction wear of a rubber disc and a mating part, and the device cannot well simulate the actual use condition as described above. Moreover, in a simulated environment, these devices are rarely able to simultaneously simulate the effects of temperature, tension and frequency changes on rubber fatigue performance.
Therefore, there is a need to provide a new rubber roller friction wear test device, which can comprehensively simulate the field working environment and state of the rubber roller, such as temperature, tension, rotation speed, environmental medium and other conditions, and provide reliable data for the subsequent reasonable formulation of the process flow and the improvement of the product production quality of the subsequent process.
