一种超细长高精度铁心冲片的加工

Processing of a Iron Core with Super Slender and High Precision

在自行研制的新产品电动机中,其定子铁心冲片属一种超细长高精度铁心冲片。冲片常规的加工方式为冲制。对于常规的整体式冲模,因其自身的制造精度要求过高,无法实现对超细长高精度铁心冲片的冲制。在研制过程中,经过对多种加工方案进行分析研究,对冲制该冲片的冲模结构进行了改进,将常规的整体式冲模改为分瓣拼合式冲模。经实际制造该分瓣拼合式冲模及实际冲制表明,使用该超细长高精度铁心冲片可一次冲制成型,尺寸和精度均满足要求,并且质量稳定,生产效率高。

In the self-developed new products motor,the stator core laminations is a long genus superfine precision core punching.The conventional processing methods for hedge sheet is the punching.However,since the conventional monolithic die with their high manufacturing precision and no meet the requirements,so the conventional monolithic die can not achieve the precision of ultra-fine long core of punching punching.In the contrast research process,the analysis of multiple processing program and the ultimate hedge made of die punching improve the structure of the conventional monolithic die with the following：sectional split type die.By the actual manufacturing of the sectional split type die and the actual punching,the ultrafine long precision punching has the satisfied type and size,accuracy requirement,stable quality,and high production efficiency.
