高精度仪表零件精冲结构分析与质量控制

Fine-Blanking Molds' Structure Analyze and Quality Control of High Accuracy Meter Parts

精冲件的尺寸精度主要取决于模具的制造精度、刃口状态、材料的种类、厚度、金相组织、零件的几何形状的复杂程度、工艺润滑、力学性能参数以及压力机的选用与调整等。基于精密冲裁件的质量要求,对高精度仪表零件精冲结构设计进行分析,以保证精密冲裁加工件质量控制。

Fine-blanking molds’ dimensional accuracy depends largely on manufacturing accuracy,conditions of the cutting edges, categories、thickness and metallogrophic structure of material, the parts geometrical shape complexity,technological lubrication,？mechanical parameters and the selection and adjustment of the punching machine,etc. Based on the quality request of delicate blanking parts,the paper analyze the high precision meter parts’ blanking structure design and certify the quality control of the precision blanking processed pieces.
