型砂性能自动检测装置的研究与设计

为了保证铸造用砂的质量,研制了一种型砂自动检测装置。该装置在混砂的同时连续取样,用浮动的压轮对砂样压实以连续检测紧实率,对压后的条形砂样的悬臂长度连续测量以测定抗弯强度。介绍了该装置的工作原理、控制过程及机械结构设计、电控软件的设计方法,并给出了应用该系统的实测结果。

Design and Research on Automatic Detection Device of Green Sand Properties

In order to control the quality of the casting sand, a new type of automatic detection device was developed. It can continual sample while mixing the green sand, using the floating pinch wheel to compaction the sand specimen, so it can detect the compactability continuously, the cantilever length of bar sand specimen can be measured continuously, by which the bending strength is detected. The principle, the control process and the mechanical structure design are introduced as well as the experiment result.
