我厂自制的可调大弧线气割夹具,是一种简便的工艺装备,配合氧—乙炔半自动切割器,便可准确地切割各种弧形板料,保证了板材的曲线形状精度。可调大弧线气割夹具(见图1),由中间骨架、凸弧导轨、凹弧导轨组成。两种弧线导轨分别用若干件M8×400的双头螺杆和六角螺母连接起来,当氧—乙炔半自动切割器安装在凸形导轨上进行,便可切割外圆弧线,在凹形导轨上运行便切割出内圆弧线。 Our factory-made adjustable large arc gas cutting fixture, is a simple process equipment, with oxygen - acetylene semi-automatic cutter, you can accurately cut a variety of arc-shaped sheet to ensure the accuracy of sheet metal curve shape. Adjustable arc gas cutting fixture (see Figure 1), the middle frame, convex arc guide rail, concave arc guide rail. Two kinds of arc guide rails are respectively connected with several M8 × 400 double-headed screws and hex nuts. When the oxygen-acetylene semi-automatic cutter is installed on the convex guide rail, the outer arc can be cut, and on the concave guide rail Running will cut out the arc line.
