随着技术的进步和电子技术的应用,硬度计的生产技术已经有了显著改善.本文阐述了从洛克威尔(洛氏)原理中扩展出来的一种派生形式,这种派生形式显著地扩大了硬度计的使用范围.为了能对本文有一个清晰的概念,首先应简要地介绍一下洛氏原理,原理中的几个测试步骤如图1所示,图1还包括一只度盘式指示器以及一只硬度试验压头,这只硬度试验压头能够自动测出最明显的移动.如图1中左侧所示,待检测的金属表面必须与标准硬度试验压头相接触,并且必须对这个表面施加一个初始载荷、即预压F_0, 以给表面第一次压入,然后将度盘式指示器调至零位.
With the advancement of technology and the application of electronic technology, the production technology of durometers has been significantly improved.This article describes a derivative form that extends from the Rockwell principle, which extends significantly In order to have a clear concept of this article, first of all should briefly introduce the Rockwell principle, the principle of several test steps shown in Figure 1, Figure 1 also includes a dial indicator And a hardness test pressure head, the hardness test pressure head can automatically detect the most obvious movement shown in Figure 1 on the left, the metal surface to be tested must be in contact with the standard hardness test pressure head, and must Apply an initial load to this surface, preloading F_0 to force the surface in for the first time, then set the dial indicator to zero.
