DL-8442刀具力度测试仪
DL-8442 Blade strength testing apparatus
该测试仪是根据ENISO8442-1：1997标准中的有关章节而设计制造的。主要原理为在刀具施加的力，并保持10S时间，然后撤去施加力，测出其变形角度。
This testing apparatus is designed and manufactured according to the related clause of EN ISO 8442-1:1997 standard. Main principle: add force to blade center for 10 seconds, and then remove added force and measure distortion angle.
该测试仪由PLC可编程序控制器、液晶触控显示屏、步进电机控制的传动机构、百分表显示的实测挠度、打印机等组成。可设定规格、跨距，在触控屏上实时显示实测挠度、试验时间、受力弯曲角度、变形角度，并可由打印机打印出测试数据。
This testing apparatus consists of PLC programmable controller, LED, tranission organization of step motor, printer and etc. Specification and span can be set. Touch screen displays test time, distortion angle and etc on real time. And printer can print the testing data.
