Hardness measurement device and hardness measurement method

Abstract

The invention relates to the technical field of hardness measurement and discloses a hardness measurement device and a hardness measurement method. The hardness measurement device includes: a test ball (1); a first channel which enables the test ball to slide down and a second channel (9) which enables the test ball to move in a horizontal uniform linear motion manner; the first channel includes a1 / 4 arc channel (4) which has a vertical inlet and a horizontal outlet, wherein the outlet of the 1 / 4 arc channel is crossed with the inlet of the second channel to form a communicated connection unit, which has a free end extended far away from the outlet of the second channel; the free end is pressed against a to-be-tested material; the second channel is provided with a test component, which isused for monitoring the time that the test ball passes through any one area on the second channel. On the basis of a Shore method for measuring metal hardness, fuzzy hardness value measurement can beconverted into clear time measurement, so that test precision and accurate are effectively improved, and the obtained hardness value is more accurate.

Description

technical field [0001] The invention belongs to the technical field of hardness testing, and in particular relates to a hardness measuring device and a hardness measuring method. Background technique [0002] The traditional method of measuring the hardness of building materials only expresses the hardness by the number of times the ball hits the sample or the depth of the metal indentation. This method is complicated to operate manually, the efficiency of the instrument is low, and the accuracy is not high enough. It is easy to cause fatigue to the operator. The error is relatively large, and it is no longer suitable for the needs of today's social development. [0003] At present, the most widely used method of hardness measurement for building materials is the Shaw method, which is mainly to drop a small ball freely from a certain height to hit the sample. The harder the sample is, the more energy the ball will consume in breaking the sample. The smaller the ball, the gr...
