System for making braces for dies
A system and method for producing braces for a cavity die having a predetermined shape are disclosed. The system includes an input file containing information about the shape of the cavity die and a bracing program running on a computer. The bracing program produces an output file based on the input file and brace parameters. The output file includes information about the design of the braces. The computer instructs a brace-making machine to produce the braces based on the information in the output file. The method includes the steps of: a) providing input information about the shape of the cavity die and the brace parameters to the computer; b) processing the input information by the computer to produce an output file containing information about the design of the braces; and c) producing the braces in accordance with the information from the output file.
1. An apparatus for producing a brace for a cavity die from a strip of material, the apparatus comprising:
a) a bed for supporting the strip of material, the bed including a plurality of flanges along a first side of the bed and which define a reference edge;
b) a material feeder for moving the strip of material in a first direction generally parallel to the reference edge;
c) a cutting tool movable in a second direction generally perpendicular to the reference edge across the strip of material;
d) a control system for coordinating the movement of the material feeder and cutting tool to make a desired cut in the strip of material;
e) a piston assembly mounted to a second side of the bed opposite the first side of the bed, the piston assembly adapted to push the strip of material generally in the second direction from a hopper located along the second side of the bed onto the bed; and
f) at least one guide mechanism mounted to the second side of the bed and located adjacent the piston assembly between the hopper and the flanges, the at least one guide mechanism movable between a retracted position and a contact position,
wherein in the retracted position the at least one guide mechanism is lowered substantially beneath the bed allowing the piston assembly to push the strip of material generally in the second direction from the hopper onto the bed, and
wherein in the contact position the at least one guide mechanism bears against the strip of material on the bed to bias the strip of material against the flanges of the bed.
2. The apparatus of claim 1 , further comprising a cutting tool servo adapted to move the cutting tool, and wherein the material feeder comprises a material feed servo adapted to move an electromagnetic clamp.
3. The apparatus of claim 2 , wherein the control system comprises a program logic controller, the program logic controller adapted to receive instructions from a computer to cut the braces, the program logic controller adapted to transmit the instructions to the material feeder and the cutting tool, wherein the program logic controller comprises a servo controller operatively connected to the material feed servo and the cutting tool servo.
4. The apparatus of claim 1 wherein each of the at least one guide mechanism includes a vertical roller that is spring biased towards the reference edge of the bed.
5. The apparatus of claim 1 wherein the at least one guide mechanism is positionable at a variable distance from the reference edge.
6. The apparatus of claim 4 wherein the at least one guide mechanism further comprises a block and a guide base, wherein the vertical roller is held within the block and the block is spring mounted to the guide base thereby enabling the block to be lowered in relation to the bed when the strip of material passes from the hopper to the bed.
