KINETIC CALCULATION OF AN AUTOMATIC TAPPING MACHINE

Abstract

This paper presents the results of the kinetic design of an automatic tapping machine, which produces threading nuts for electrical devices. The machine performs all functions of separating and feeding the workpieces, clamping and tapping the M4 nuts automatically. The determined kinetic papameters includes cutting velocity, kinetic transmission chains, spindle speed and kinetic control with subject to demanded production rate. The pilot operations showed that the production rate can reach 35 nuts per minute. The machine designed is promising for mass producing of small nuts.
