环锭细纱机新型传动管零件加工工艺改进

Improvement on Processing Technology for New Transmission Pipe Parts of Ring Spinning Frame

为提高环锭细纱机新型传动管零件的加工质量和效率,满足JWF1572型棉纺环锭细纱机产品转批后传动管零件的批量生产需求,分析传动管零件加工现状以及加工过程中存在调头难度大、劳动强度大等难点的原因;根据新型传动管零件的结构特点和加工技术要求,详述使用双头铣床加工两端面、加长钻孔专机设计、制作专用倒角刀具、刀盘以及加长钻孔工作台面等对原有工艺的改进措施。指出:工艺改造后无需零件调头,以铣代车,可实现1次装夹完成两端面以及内外孔口倒角,缩短加工工艺流程,减少零件装夹次数及磕碰划伤等问题;制作钻孔工序加长台面,原材料利用率提高,零件加工费用降低,工序集中,提高了零件加工质量与加工效率。

In order to improve the processing quality and efficiency of the new transmission pipe parts of ring spinning frame and meet mass production demand of the transmission pipe parts of JWF1572 cotton ring spinning frame after batch transfer,the difficulties in the processing of the transmission pipe parts are analyzed,such as difficulty in turning around and labor intensity.According to the structural characteristics and processing technical requirements of the new transmission pipe parts,the original process is improved by using duplex head milling machine to process two end faces,lengthening the drilling machine design,making special chamfering cutter,cutter head and lengthening the drilling work table,which can achieve one clamping to complete the two end faces and the internal and external chamfering,shorten the process flow,reduce number of clamping parts and knock scratches and other problems.It is pointed out that there is no need to turn the parts around after the transformation,and the milling instead of turning can improve the utilization rate of raw materials.The production and drilling process lengthens the table,reduces the processing cost of parts,centralizes the process,shortens the process flow,reduces the labor cost,and improves the processing quality and efficiency of parts.
