Abstract

The invention discloses a method for calibrating the hardness indicating value of a rubber hardness gauge and standard blocks, relating to a metering calibration technology. The calibrating method comprises the following step of: calibrating the standard blocks for the hardness indicating value of the rubber hardness gauge, wherein the standard blocks for the hardness indicating value of the rubber hardness gauge comprise an A-type standard block group, a C-type standard block group, a D-type standard block group and an F-type standard block group; the standard block group of each type comprises at least six individual standard blocks of different hardness values; each individual standard block comprises a metal inverted long groove body; a groove is formed at the groove bottom; or each individual standard block comprises a base block, an elastic sheet and a cover plate; the elastic sheet is arranged at the convex cutting edge position of the base block in the form of flat plate; and the profile body of a cover body is covered on the base block in cooperation with the base block, and is contacted with the elastic sheet. The calibrating method is quick, and the artificial errors are fewer; and the standard blocks have skillful and simple structures, easily-stored calibration value and low cost, are convenient to manufacture and carry, are quick for grasping relevant calibrating technologies and are convenient for plant inspection.

Description

technical field [0001] The invention relates to measurement and calibration technology, in particular to a method and a standard block for calibrating the hardness display value of a rubber hardness meter (type A / C / D / F) for testing rubber, sponge and plastic. Background technique [0002] Rubber hardness tester (A / C / D / F type) can test the hardness of rubber, sponge and plastic, etc., when testing different products, choose different types of hardness tester, such as A type, or C type, or D type, or Type F. [0003] figure 1 Shown is the standard block of the hardness indication value of the rubber durometer in the prior art. The calibration method and the standard block of the hardness indication value of the rubber durometer in the prior art are as follows: [0004] Adjust the up and down adjustment knobs of the fixed frame 1 so that the calibrated rubber hardness gauge 2 is at an appropriate height so that one end of the force-applying balance 3 touches the indenter of ...
