图示专用仪器用于研究扁平工件在成型过程中薄壁的变形状态,这种仪器还可应用于机械制造中高精度的划线工作。带材8置于上下板块之间,以便使所需要的带材部分处在划线区内。上板块通过手柄7下放至带材上,并在工作过程中以本身重量压住带材。这时划针15抵住带材表面,千分表12则显示出其厚度。通过手柄1移动滑块9的同时进行划线。根据轮廓限制器6的位置来确定划线部分。柱销14在沿
The special instrument is used to study the thin-walled deformation state of the flat workpiece in the forming process. The instrument can also be applied to the high-precision marking work in the machine manufacture. The strip 8 is placed between the upper and lower plates so that the desired strip portion is within the scribe line. The upper plate is lowered onto the strip by the handle 7 and pressed against the strip by its own weight during operation. At this moment, the needle 15 is pressed against the surface of the strip, while the dial gauge 12 shows its thickness. Scribing is performed while moving the slider 9 by the handle 1. The scribed portion is determined according to the position of the contour stopper 6. Pin 14 is along
