在电器行业和仪器仪表行业中,经常需要在产品上加工直径小于3mm的小锥孔。一般均采用在冲模上安装如图1所示凹模套的方法。但对大多数中小型厂,往往缺乏专用的精密设备,要使加工出的凹模套达到规定的技术要求,是比较困难的。我厂模具车间在生产实践中,试制出小锥孔四刃铰刀,可铰制φ1～3mm的锥孔。收到了较好的技术经济较果,现介绍如下。
In the electrical industry and instrumentation industry, often need to process small cone diameter of less than 3mm in the product. Generally used in the die on the die as shown in Figure 1 installed sleeve method. But for most small and medium-sized factories, it often lacks specialized precision equipment. It is quite difficult to achieve the specified technical requirements for the processed female die sets. I plant die workshop in the production practice, try out a small cone four-blade reamer, can be tapered φ1 ~ 3mm cone hole. Received a better technical and economic consequences, are presented below.
