概述:汽轮机隔板汽叶的型线是由园弧、直线两部分组合而成,以往国内各汽机制造厂、修造厂,一般采用冷压、冷校或热压、冷校的工艺。即汽叶的型线先采用冷(热)压初成型,然后由钳工锤击整形来达到型线的精度要求。汽叶的成型工序效率及质量在一定的程度上与钳工的技术熟练程度有关。为了减轻劳动强度,提高汽叶的型线精度,我厂目前采用热压
Overview: Steam turbine diaphragm is the shape of the arc from the park arc, straight line from the combination of two parts, in the past domestic steam turbine manufacturer, repair plant, the general use of cold, cold or hot school, cold school process. That is, the profile of the steam turbine is first cold (hot) pressure forming, and then by the fitter hammering shaping to achieve the accuracy of the profile line. Vapor formation process efficiency and quality to a certain extent with the fitter’s skill level. In order to reduce labor intensity and improve the profile accuracy of steam leaves, I plant the current hot pressing
