Methods for setting-up a female blanking die for a die cutting machine for d ie cutting and/or blanking a carton blank, and universal press frames for use i n such setting-up are all provided herein. The first stages in the erection of the female blanking die, which includes a rectangular framework of a front rail, a rear rail and two side rails, involve accurate placement of a template within the rectangular framework. A ll the rails are provided with a dovetail groove along its inside edges. This is achieved by the use of centre line orientation cylinders on a template, a centre line rod throug h aligned holes in the centre line orientation cylinders and centre line brackets at the precise centre point of the front and the rear rails. The template is mounted atop the centre lin e brackets by means of the centre line rod and rests loosely on template corner locking clamps. Then the template is secured to the accurately-placed template corner locking clamps in the rectangular frame, and is accurately-positioned and fixed there. The centre line cylinders are then removed and grid orientation cylinders are mounted on the template. A plurality of grid support members are selectively-disposed along the internal perimete r of the rectangular framework by cooperation with the dovetail grooveof the rails. The grid comprising a plurality of intersecting rails, the pattern of the intersectin g rails having a predefined shape, is disposed within slots within the grip support members a nd in the grid orientation cylinders and is locked into place in the grid support member. A plurality of jogger members are provided which are selectively-disposed alon g the internal perimeter of the rectangular framework by means of cooperation with the dovetail groove of the rails, each jogger member having a particularly-recit ed structure. The plurality of auxiliary adjustable support members may also be selectivel y- disposed along the internal perimeter of the rectangular framework by means of cooperation with the dovetail groove of the rails. The universal press frame is supported on four legs. When the template is dropped below the universal press frame, and the legs a re removed, the universal press frame becomes the female blanking die. |
