Abstract
An adjustable die assembly is shown for forming a template having a plurality of holes each having a medial lug portion. The die assembly is mounted in a base member that has a graduated dial plate. The template is first provided with a plurality of starter holes. The die has a post surrounded by an annular recess except for a medial lug portion. The die is first set at a particular angular relationship to the dial plate. A template hole to be processed is fitted over the post. The base member includes an adjustable cross bar for alignment of the template with respect to a datum plane. A punch is then assembled on the die post and passed through the template for forming the holes with a medial lug portion in various angular positions.
Claims12
An adjustable punch and die assembly for forming in a template a plurality of holes with various medial lugs, said assembly comprising:
- a base member having a top table surface with a recess having an angularly adjustable die positioned therein, a fixed dial plate having a series of angular graduations surrounding the recess and cooperating with the die;
- the adjustable die having a vertical post over which one of a plurality of holes in a template is adapted to slip thereover, an annular area of the die surrounding the base of the post being recessed except for a medial lug portion, and a die index pointer carried by the die and cooperating with the dial plate for positioning the die at a predetermined angle;
- an adjustable alignment means supported on the base member and movable toward and away from the die and adapted for aligning a template supported on the die relative to a datum plane;
- and an annular punch having a vertical bore for mating with the post of the die member, the lower portion of the punch being adapted to mate into the recessed annular area of the said die, the punch having a cut-out portion to prevent interference with the medial lug portion of the die so that the punch is capable of forming the holes in the template with medial lugs at predetermined angular relationships.
A punch and adjustable die assembly for use with a template having a plurality of starting holes so as to provide at least some of the holes with a medial lug at various angular relationships, said assembly comprising:
- a base member having an angularly adjustable die positioned therein, with a graduated dial means cooperating therewith;
- the adjustable die having a vertical post adapted to receive a hole of the template thereover, an annular area of the die surrounding the post being recessed except for a medial lug portion, and a die indexing means carried by the die and cooperating with the graduated dial means for adjusting the die to predetermined angular relationships;
- an adjustable alignment means supported on the base member and guided for movement toward and away from the die post and adapted to align a template plate supported on the die post relative to a datum plane;
- and a punch having a bore for cooperation with the die post, the punch having a transverse cutting cross-section that matches the annular recessed area of the die minus the said medial lug portion.
The method of making a template with a plurality of holes and to provide at least some of the holes with a medial lug at various angular relationships, which method comprises the steps of:
- forming a plurality of starting holes in the template, and
- providing an adjustable die assembly with a base member for receiving the die therein, and
- providing the base member with a graduated dial plate and the adjustable die with a cooperating indexing means for setting the die to various angular relationships, and
- providing the die with a post to receive a hole of the template in succession thereover, and
- providing the die with an annular recess surrounding the die post except for a medial lug portion, and
- providing the base member with an adjustable alignment means that is guided for movement toward and away from the die post and cooperates with the template when assembled over the die post to engage and align the template relative to a fixed datum plane, and
- fitting a punch that mates into the recess of the die over the die post for passing through the template and creating the medial lug portion for each hole in succession.
The method of making a template with a plurality of holes and to provide the holes with a medial lug at variable angular relationships, which method comprises the steps of:
- forming a plurality of starting holes in the template, and
- providing a base member with an adjustable die assembly and with a graduated dial plate for setting the die at various angular postions, and
- in succession placing a hole of the template over a post of the die and,
- providing the base member with an adjustable alignment means that is guided for movement toward and away from the die post and cooperates with the template when assembled over the die post to engage and align the template relative to a fixed datum plane, and
- fitting a punch over the die post for passing through the template and creating the desired medial lug for each hole in succession.
