一、概述底板是缝纫机中的一个重要零件。工艺复杂,加工工位多,精度要求高,过去生产中,劳动强度大,生产效率低。目前,国内缝纫机底板的加工大多采用流水线作业。73年,在轻工业部组织下,由大连组合机床研究所和上海缝纫机二厂、南京轻工机械厂等单位联合设计制造了由电液联合控制的底板加工自动线。上海缝纫机一厂在原有2台鼓轮式组合机床的基础上,又设计制造了一条底板铣削组合机床自动线,这样就形成了由一条自动线和二台鼓轮机床组成的一条底板加工生产线。
First, an overview Bottom of the sewing machine is an important part. Complex technology, processing stations and more precision requirements, the past production, labor-intensive, low productivity. At present, most of the processing of domestic sewing machine floor using pipeline operations. 73 years, under the organization of the Ministry of Light Industry, the Dalian Automatic Machine Tool Research Institute and the Shanghai Sewing Machine Factory, Nanjing Light Industry Machinery Factory and other units jointly designed and manufactured by the electro-hydraulic control of the floor automation line. On the basis of the original two drum-wheel combined machine tools, Shanghai Sewing Machine Factory also designs and manufactures an automatic line-milling combined machine tool, thus forming a floor processing line composed of an automatic line and two drum machine tools.
