过去,我厂车制并条机的喇叭口工件时,用φ50圆钢,先截成200毫米长的一段,然后装夹在C620车床上,用普通刀具加工,效率低、质量差,既浪费工时又浪费钢材。为此,我们经过反复研究、多次试验,制成高速挤压成型刀具。一、刀具的结构及制做方法刀杆采用45钢圆钢,刀头采用两块YT30硬质合金,铜焊在刀杆的顶端,磨成双刃R13, In the past, the flare work piece of the draw frame of our factory was made of φ50 round steel, first cut into a length of 200 mm and then clipped to a C620 lathe, which was processed by ordinary tools with low efficiency and poor quality, which wastes Working hours waste steel. To this end, we have repeatedly studied and tested many times, made of high-speed extrusion tool. First, the structure of the tool and making method Arbor with 45 steel round bar, the blade using two YT30 cemented carbide, brazed at the top of the arbor, ground into double-edged R13,
