Abstract
Applique or similar object is simultaneously formed and affixed to a baseplate by juxtaposing a plate of contributing material adjacent the baseplate and forcing a punch entirely through the contributing material to shear the object from the plate of contributing material. The object, in turn, shears a slug from the baseplate, which is positioned against a die opening, forming an opening in the baseplate in which the object is retained by interference fit. The method may be used to affix objects from a contributing material that is either harder than or softer than the baseplate material.
Claims17
A method producing a composite article by simultaneously forming an object and permanently retaining said object to a baseplate comprising the steps of:
- providing a baseplate and a plate of contributing material, each of said baseplate and said plate contributing material being responsive to a shearing force by fracturing at a substantial angle with respect to the direction of said force;
- juxtaposing said plate of contributing material adjacent said baseplate;
- positioning said plates between a punch and die configured to the approximate shape of said object;
- forcing said punch into said contributing material to shear said object with a positive breakout angle from said plate of contributing material;
- and
- applying sufficient force to said punch to cause said object to shear a slug from said baseplate, thereby forming an opening in said baseplate and pressing said object into said baseplate opening, said slug having a size substantially determined by the shape of said die, said die having a size predetermined to cause said slug to be smaller than said object such that said object is retained in said baseplate opening by interference fit.
