When the quasi- owner data to be acquired are the application test forces under regulatory requirements, the depth of cup measured, Rockwell apparatus standard
Machine needs to extrude 6 impressions on Rockwell hardness block, and first impression is ignored, remaining 5 impression needs is uniformly distributed,
(two adjacent indentations centre distances should be not less than 4 times of impression diameter, and be not less than 2mm, impression center to hardness block edge
Distance should be not less than 2.5 times of impression diameter), while it is hard using Henan Province's metering institute's net weight type Rockwell to identical block of hardness
Degree Standard Machine carries out artificial reconnaissance, artificial impression measures and carries out hardness ga(u)ge and verifies surely and (avoid the impression having already appeared), compares
Data are as shown in the table:
Should be apparent that by upper table: it is essentially identical that two standard machines get resulting hardness number ready to same block of hardness,
That is it is ensured using the accuracy of the application Standard Machine and method hardness number detected and the hardness uniformity, together
When the application and this Standard Machine is more preferable than the uniformity of old-fashioned net weight type Standard Machine, and can with automatic point selection, avoid due to
Artificial origin and the error generated；Its calibration method is simple, can only need to fix standard Rockwell hardness block to be checked can be completed reconnaissance,
Get, measure a series of actions of depth of cup ready.Reconnaissance, get ready, measure depth of cup and obtain quasi- hardness number step all from
Dynamic to complete, time, repetitive error and human error needed for shortening calibrating on a large scale realize automatic, multiple reconnaissance, thus
Reach and improve detection accuracy, expand detection range and simplify the target of testing process, it is Rockwell hardness that easy to use, effect is good
Innovation in detection device has good social and economic benefit.
