工程机械的许多零件或部件装着用各种纸板、石棉板、软木纸、胶皮等材料加工的平垫,这些平垫若用人工剪制,不但费工费力,尺寸形状不易保证。为此,我们做了一套切割平垫的简单工具(见附图),其取材方便,制作容易,效果良好。切刀14用高碳钢车制(外径φ60～70),经热处理达HRC>45,然后磨削刃口,力求锋 Many parts or components of construction machinery are filled with flat mats made of various kinds of paperboard, asbestos board, cork paper, rubber and other materials. If these flat mats are cut by hand, they are not only laborious but also difficult to ensure dimensional shapes. For this reason, we made a simple tool for cutting flat pads (see the attached drawing), which is easy to draw, easy to make, and effective. The cutter 14 is made of a high-carbon steel car (outer diameter φ60 to 70), heat-treated to an HRC > 45, and then the cutting edge is sharpened.
