    • PURPOSE:To efficiently cut off the plate of closing belt to be collected for a spherical tank, by fixing a cutting jig, to which a rail is mounted, to a predetermined position on a sheet material and allowing a self-propelled saw to run on the rail. CONSTITUTION:A sheet material 1 of aluminum is placed on a wooden bed 2. A cutting jig 5, to which a self-propelled saw 3 and a running rail 4 of the self- propelled saw are mounted, is fixed to a predetermined position on the material by an I-bolt 6 and a hanging metal fixture 8 and clamps 12. The sheet material 1 of aluminum is cut off by allowing the self-propelled saw 3 to run on the rail 4 further rotating a saw tooth 3A of the saw 3. Here the speed of cutting is suitably selected by a thickness or the like of the sheet material 1 of aluminum but set to a speed of about 1m/min.
    • 目的:为了有效地切除要收集的球形容器的封闭带板,通过将安装有导轨的切割夹具固定在片材上的预定位置,并允许自走锯在其上运行 铁路。 构成:将铝板材1放置在木床2上。安装有自行式锯的自走锯3和行进轨道4的切割夹具5固定在预定位置上 该材料由I型螺栓6和一个悬挂的金属夹具8和夹具12.铝的片材1通过允许自推进的锯3在导轨4上运行而进一步旋转锯的锯齿3A 这里,切割速度通过铝片材1的厚度等适当选择,但设定为约1m / min的速度。
