Electron Automobile Rotational Speed Instrument Movement Part——Analysis of Forming Technique and Econotaic Benefits of a Plate

分析了电子式汽车仪表转速表机芯关键零件之一极环的成形工艺及经济性,并把设计该零件模具的几种设想作对比,得到既经济,效率又高的零件成形工艺.

In this paper,it is tc be analysed for 'he forming technique and economic benefits of a plate that it is one of key parts in the electron automobile rotational speed instrument movement. By comparing several die design methods, we obssin the forming technique of the plate,and the technique is ecnomic and efficient.
