Abstract

An alignment mechanism for punch presses and the like, comprising a base having an upper support surface; the upper support surface having a plurality of load oriented spaced shaped recesses; a base alignment sleeve positioned in each of the recesses and conforming thereto and extending upwardly above the upper support surface; a frame positioned on the upper support surface and having a portion extending upwardly therefrom; the frame having a first set of a plurality of load oriented spaced shaped recesses for cooperating with the plurality of base recesses for positioning the alignment sleeves in the first set of recesses for aligning the frame with the base; the upwardly extending portion of the frame having an uppermost surface; the uppermost surface having a second set of a plurality of load oriented spaced shaped recesses; a crown alignment sleeve positioned in each recess of the second set of recesses and conforming thereto and extending upwardly above the upper row surface; a crown positioned on the uppermost surface; and, the crown having a plurality of load oriented spaced shaped recesses for positioning the alignment sleeves of the second set of recesses in the crown recesses for aligning the crown with the frame is disclosed herewith.

An alignment mechanism for punch presses and the like, comprising:

(a) a base having an upper support surface;
(b) said upper support surface having a plurality of load oriented spaced shaped recesses;
(c) a base alignment sleeve positioned in each of said recesses and conforming thereto and extending upwardly above said upper support surface;
(d) a frame positioned on said upper support surface and having a portion extending upwardly therefrom;
(e) said frame having a first set of a plurality of load oriented spaced shaped recesses cooperating with said plurality of base recesses and adapted for receiving said alignment sleeves in said first set of recesses and for thereby aligning said frame with said base;
(f) said upwardly extending portion of said frame having an uppermost surface;
(g) said uppermost surface having a second set of a plurality of load oriented spaced shaped recesses;
(h) a crown alignment sleeve positioned in each recess of said second set of recesses and conforming thereto and extending upwardly above said uppermost surface;
(i) a crown positioned on and secured to said uppermost surface;
(j) said crown having a plurality of load oriented spaced shaped recesses cooperating with said second set of recesses and adapted for receiving said alignment sleeves of said second set of recesses in said crown recesses and for thereby aligning said crown with said frame;
(k) said frame having an upper end and a lower end;
(l) die means associated with said lower end;
(m) longitudinally displaceable die adjustment means associated with said upper end;
(n) laterally displaceable wedge means slideably bearing on said die adjustment means for longitudinally displacing said die means when said wedge means is laterally displaced;
(o) drive means associated with said crown and connected to said wedge means for laterally displacing said wedge means;
(p) a pair of spaced parallel opposed gib means fastened to said crown adjacent said frame upper end and extending below said uppermost surface;
and,
(q) said wedge means having a pair of opposed shoulders engaged with said gib means and adapted for being guided thereby during lateral displacement.
