Abstract
The present invention is a bending machine for bending material such as steel to form cutting dies for products such as cloth, leather or the like. Coiled material is fed through a material washer, straightener and printer by a material feeder to a bending head. If required the material is forwarded through the bending head to a heating unit and retracted to the bending unit to aid in bending. A nicking tool is also provided ahead of the bending tool to nick the material. The nicks enable the cutting die to cut notches in the product being cut. A support surface at the output end of the machine supports the material as it is bent into the required form.
Claims18
A bending machine for producing cutting dies from material, said bending machine comprising:
- a) a feeder for accepting said material;
- b) a bending tool accepting said material from said feeder for bending,
- c) a support surface for supporting said material upon output from said bending tool,
- d) a heating unit, and
- e) a nicking unit,
- wherein said heating unit and said nicking unit are disposed on intersecting planes such that said material need not be moved once in position to engage either or both of said heating unit and said nicking unit.
A bending machine for producing cutting dies from material, said bending machine comprising:
- a) a feeder for accepting said material;
- b) a bending tool accepting said material from said feeder for bending,
- c) a support surface for supporting said material upon output from said bending tool, and
- d) a material cleaner
- wherein said material cleaner is connected to said bending machine by a bracket having a plurality of pivot points, said pivot points permitting said material cleaner to adjust to bends in said material.
A method of creating a cutting die for a work product, said method comprising the steps of:
- a) extracting material from a source of material;
- b) feeding said material to a bending tool;
- c) bending said material;
- d) supporting said material after bending;
- e) repeating steps a) through d) until said cutting die is complete;
- f) detaching said cutting die from said source of material, after the completion of step e);
- and
- g) nicking said material to incorporate notches in the work product.
