Stamping Die Design of a Kind of Textile Machine Needle

摘要

This paper introduces a stamping die design of a kind of textile machine needle. According to the size, material and mass production requirements of needle, the blanking technological property of parts are analyzed, and its general principles, methods and steps of die design are introduced. The structure of stamping die is gap-frame press, and JB23-25 is selected to do the work. The dimensions of cutting edge and dimensional tolerance are calculated. Finally designing components, checking stamping equipment and drawing assembly diagram are finished. This stamping die is mainly composed by punch die and concave die, positioning parts, discharge unit, die set, stamping machine and fasteners.
