加工如图1所示的工件,长785毫米,内孔中有三个等分键槽,是我厂长期的生产关键。通过三结合,设计了一种如图2所示的结构简单、只加垫片的单键拉刀。此拉刀经过使用,效果良好,达到技术要求,且操作方便,辅助时间少,生产效率高,并可节约大量的高速钢,降低工具成本。一、结构原理此拉刀的结构原理如一般单键拉刀。刀体1的槽内装入拉刀片2,刀片下面放入垫片4,刀片和垫片是用三个M6螺钉3固紧于刀体上。在刀片的后端有
Processing of the workpiece shown in Figure 1, length 785 mm, the hole has three equal keyway, is the key to our long-term production. Through the combination of three, designed a simple structure, as shown in Figure 2 only pad single broach. The broach after use, the effect is good, to meet the technical requirements, and easy operation, less auxiliary time, high productivity, and can save a lot of high-speed steel and reduce tool costs. First, the structural principle The structure of the broach such as the general single-key broach. The cutter body 1 is loaded with a pull-in blade 2 in a groove, a washer 4 is placed under the insert, and the blade and the washer are fastened to the cutter body with three M6 screws 3. At the back of the blade there
