Problems solved by technology

[0006] Practice shows that the friction coefficient changes with the pressure N and the sliding velocity V. The current friction coefficient measurement device does not take into account the influence of the pressure N and the sliding velocity V on the detection results. The coefficient of friction of the device under V is necessary

Abstract

The present invention provides a friction coefficient detection device, which includes friction heads arranged oppositely on the same axis, the sample is arranged between the friction heads and perpendicular to the axis, and the device includes a universal pull test machine, a base fixedly connected to the detection table of the universal tensile testing machine, a sleeve connected to the base and opposite to the opening; one end of the friction head is respectively arranged in the sleeve; one of the sleeves A pressure sensor and a pressure adjustment assembly are also arranged in the cylinder; the pressure sensor is connected with the friction head; the sample is connected with the clamp at one end of the tensile arm of the universal tensile testing machine. The device can detect the friction coefficient of specific material samples 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 it can also be used for its application. Provide accurate guidance accordingly.

Description

technical field [0001] The invention relates to a detection device, in particular to a friction coefficient detection device. Background technique [0002] With the development of the economy and the progress of society, more and more precise control in production and life has been favored by people, and this situation is especially obvious in industrial production. In the current industrial production, precise control, intelligent production, and unmanned operation are becoming more and more mature. Most of these high-tech technologies rely on accurate data foundation. Therefore, in modern industry, the detection of materials, equipment parameters, data, etc. is very important and cannot be ignored. The parameters of materials are various and complex, and each parameter requires in-depth research. [0003] Friction coefficient is an important factor affecting the stamping performance of metal strips. The lower the friction coefficient, the better the formability of metal ...
