Abstract

A combined type elastic discharge unit comprises an upper elastic pressing bush, a lower elastic pressing bush and a spring. The upper elastic pressing bush and the lower elastic pressing bush are axially provided with through holes, the end surface of the bottom of the upper elastic pressing bush and the end surface of the bottom of the lower elastic pressing bush are fixed to each other by an inner hexagon screw after contacting with each other so as to jointly form an axial spring mounting groove; the spring is fixed into the spring mounting groove between the upper elastic pressing bush and the lower elastic pressing bush; an elastic pressing gasket is arranged between the top of the spring and the upper elastic pressing bush; and the combined type elastic discharge unit is fixed onto a limiting strip between an upper die seat of a progressive die for motor iron cores and a discharge plate seat. The combined type elastic discharge unit has the advantages that the combined type elastic discharge unit is simple in structure and convenient to use, and elasticity does not need to be readjusted when the combined type elastic discharge unit is reinstalled.

Description

technical field [0001] The invention relates to a combined elastic unloading device, in particular to a combined elastic unloading device for a motor iron core progressive die. Background technique [0002] The unloading device of the progressive die generally adopts a split type elastic unloading device. The advantages are: the distribution of the elastic force of the unloading spring is reasonable, and it should ensure smooth, stable and reliable unloading; but the elastic force of the unloading spring in the above device is through the hexagon Flat head screw plug and snap pin adjustment block to adjust. When fixing, when the thickness of the spring pin adjustment block is consistent and the depth of the hexagon socket flat head screw plug is too deep, the spring force of the unloading spring is too large. Long-term use of the mold will cause deformation of the unloading plate seat, and the service life of the mold will be reduced. When fixing, when the thickness of the ...
