Abstract
A frame assembly for a lower blanking tool of a carton die cutting machine. The frame assembly includes an outer frame comprised of a pair of opposite longitudinally extending side rails and a pair of opposite cross rails extending crosswise between the side rails. Each of the cross rails has a T-shaped slot formed therein opening to its inner surface, and each of the side rails have a T-shaped slot formed therein opening to its upper surface. Each slot extends downwardly at an acute angle with respect to a horizontal plane. A plurality of corner pieces rigidly interconnect the rails together with fasteners extending into the T-shaped slots of adjacent side and cross rails so that when tightened, the corner pieces function like clamps to rigidly interconnect the rails together.
Claims15
A corner piece for interconnecting frame members of a lower blanking tool frame assembly used in a carton die cutting machine, comprising:
- an L-shaped body having a horizontal plate member defining a substantially flat upper face, a substantially flat opposite lower face, an inside face, an opposite outside face, and an end face, and an upright plate member defining a substantially flat inner face contiguous with said upper face, a substantially flat outer face contiguous with said lower face, an inside face contiguous with the inside face of said horizontal plate member, an opposite outside face contiguous with the outside face of said horizontal plate member, and a top face;
- said horizontal plate member having at least one outwardly extending bolt-receiving bore formed therethrough, said outwardly extending bore defining an axis disposed at an acute angle with respect to said upper face;
- said upright plate member having at least one downwardly extending bolt-receiving bore formed therethrough, said downwardly extending bore defining an axis disposed at an acute angle with respect to said inner face;
- a lip projecting outwardly from the outer face of said upright plate member;
- and
- a tenon projecting downwardly from the lower face of said horizontal plate member.
