我厂在试制TSN173/21—12 500千瓦水轮发电机过程中,碰到定子扇形冲模内、外圆加工问题。由于发电机定子外圆直径为φ1730,故冲模外圆加工需要有2.3 M以上的立车才能加工。由于我厂最大的设备,仅有一台1.25M的立车。为了攻下500千瓦发电机扇形冲模加工这道难关,我厂革命职工,遵照毛主席“独立自主,自力更生”的伟大教导,自己动手,革新了一套简单的工具。我们在一台1×3M龙门刨床上,顺利地完成了冲模的车、磨任务。加工质量完全满足要求。现将加工原理简介如下:(见图)
I plant trial TSN173 / 21-12 500 kilowatts hydro-generator process, met the stator fan-shaped die, cylindrical processing problems. As the outer diameter of the stator of the generator is φ1730, the external machining of the die requires more than 2.3M vertical lathe to be machined. Due to the largest equipment in our factory, there is only one 1.25M vertical car. In order to tackle the difficult task of processing 500-kilowatt generator fan-shaped dies, our revolutionary workers and staffs followed the great example of Chairman Mao’s “independent and self-reliance” initiative and innovated a set of simple tools. We are in a 1 × 3M planer, the successful completion of the die-car, grinding tasks. Processing quality fully meet the requirements. The processing principle is as follows: (see photo)
