Automatic rivet-stacking progressive die thickness controlling and metering device for motor iron core

Abstract

An automatic rivet-stacking progressive die thickness controlling and metering device for a motor iron core comprises a steam cylinder connected with an upper die seat. The steam cylinder is connected with a drawing plate capable of sliding along the surface of the upper die seat, a retaining pin on the upper die seat is inserted into an open hole in the drawing plate to limit stroke of the drawing plate, a groove capable of containing the top end of a metering convex die is formed in the undersurface of the drawing plate, the top end is of a shape easy for sliding relatively to the groove, the metering convex die is movably arranged in a first through hole of a convex die fixing plate, a discharging fixing plate is arranged at the bottom of the convex die fixing plate, a discharging plate is arranged at the bottom of the discharging fixing plate, and the bottom of the metering convex die is penetratingly arranged a second through hole penetrating the discharging fixing plate and the discharging plate. By the automatic rivet-stacking progressive die thickness controlling and metering device, control and adjustment on thickness of the motor iron core on a multistation progressive die are realized, so that the automatic rivet-stacking multistation progressive die can produce the motor iron core different in thickness by punching.

Description

technical field [0001] The invention relates to a device for controlling and measuring the thickness of an automatic stacking and riveting progressive die of a motor iron core. Background technique [0002] The manufacturing method of the traditional motor core is to punch out the motor stator and rotor punching pieces (loose pieces) with a common die first, and then make the iron core by rivet riveting, clipping, argon arc welding and other methods after the pieces are aligned. With the application of modern stamping technology in the field of motor manufacturing, a new manufacturing method for motor cores has emerged, that is, on a pair of multi-station progressive dies, the punched strips enter the progressive dies, and then are processed in the progressive dies. Stamping through various processes on the mold (including punching the counting hole for controlling the thickness of the motor core and the boss for automatic riveting of the motor core), and the whole stamping ...
