Description

Technical Field

[0001] The utility model relates to the technical field of finished friction product detection, in particular to a performance detection device for finished friction material products. Background Art

[0002] Friction material is a component material used in power machinery, which relies on friction to perform braking and transmission functions. It mainly includes brake linings (brake pads) and clutch facings (clutch plates). Brake pads are used for braking, and clutch plates are used for transmission. The performance of friction materials is mainly reflected in three aspects: friction coefficient, wear resistance and physical properties. The friction coefficient is an important factor affecting the stamping performance of metal strips. The lower the friction coefficient, the better the formability of the metal strip. Therefore, the friction coefficient is an important input parameter for stamping process manufacturers. The current principle of measuring metal friction coefficient is as follows: f = F / (2*N), where f is the friction coefficient, F is the tension, and N is the pressure applied to the sample. Practice shows that the friction coefficient changes with the pressure N and the sliding speed V.

[0003] Chinese patent CN109975203B discloses a friction coefficient detection device, which includes friction heads arranged opposite to each other on the same axis, a sample arranged between the friction heads and perpendicular to the axis, and the device includes a universal tensile tester, a base fixedly connected to the test table of the universal tensile tester, and sleeves respectively connected to the base and with openings opposite to each other; one end of the friction head is respectively arranged in the sleeve; a pressure sensor and a pressure regulating assembly are also arranged in one of the sleeves; the pressure sensor is connected to the friction head; the sample is connected to a clamp at one end of the tension arm of the universal tensile tester. The device can detect the friction coefficient of a specific material sample under different pressures, different tensions and different moving speeds. Through the friction coefficient data under different conditions, the performance of the material can be comprehensively evaluated, and corresponding accurate guidance can also be provided for its application. However, it uses a spring for pressure application, and the potential energy of the spring will gradually decrease with the number of uses, so the device is not convenient for detecting tension.
