Sectional bar surface coating abrasion resistance detecting device

Abstract

The invention discloses a sectional bar surface coating abrasion resistance detecting device. The sectional bar surface coating abrasion resistance detecting device comprises a supporting frame and a sand containing hopper arranged at the upper portion of the supporting frame. The discharging port of the sand containing hopper is connected with the upper end of a guide pipe. A workpiece is arranged below the lower end of the guide pipe. By means of the structure, the sectional bar surface coating abrasion resistance detecting device has the advantages that the sectional bar surface coating abrasion resistance is accurately measured through the quality of an abrasion-through sectional bar surface coating, a sand guiding needle plays a role in guiding falling sand materials, the falling sand is centralized, and the centrality of the sand materials is high; the inclination angle of a sectional bar plate is conveniently adjusted through a rotating shaft structure, and installing of the sectional bar plate is convenient; by means of a positioning needle, it is guaranteed that during each-time sampling, the sand materials freely fall down to the height the same as the contact height of the sectional bar plate, and the error produced by different heights is reduced; the effect on the freely falling sand materials from wind power is prevented through a guide pipe; a lifting mechanism elevates a sand material weighing mechanism to the sand containing hopper, the sand materials in the sand material weighing mechanism flow into the sand containing hopper, and circular using is achieved.

Description

technical field [0001] The invention relates to a device for detecting wear resistance of profile surface coating. Background technique [0002] Aluminum alloy building profiles are mainly used in the construction industry and the field of housing construction. They have the advantages of light weight, beautiful structure, corrosion resistance, and simple processing. With the change of the environment and the improvement of living standards, the requirements for the corrosion resistance of the surface of aluminum alloy building profiles are getting higher and higher, so the measurement of the wear resistance of the surface coating of aluminum alloy building profiles is particularly important. Since the specific method and scope of the determination of the sand concentration ratio are not specified in the wear resistance test method stipulated by the anodic oxide film, the results of the wear resistance test are different, and some even cannot detect the wear resistance of th...

Since the specific method and scope of the determination of the sand concentration ratio are not specified in the wear resistance test method stipulated by the anodic oxide film, the results of the wear resistance test are different, and some even cannot detect the wear resistance of the surface coating, which is serious. It affects the accurate detection of the surface quality of profiles, and brings certain troubles to aluminum profile manufacturers and users
