Abstract
A die holder mounts a die to form heads on nails or screws. A top surface of the die includes a groove for longitudinally receiving and holding an elongate body. The die has a recess merging into the groove at one end of the groove to form a nail or screw head. The die is conical for press fit by contact with an inner surface of a bore or hole in the die holder. A top surface of the die is planar to a top surface of the die holder with a bottom surface engaging bottom part of the die holder. The bottom portion of the die has a recess or engaging with a corresponding protrusion die holder fixing an angular orientation of the groove relative to the die holder. Two opposite dies are brought together by two opposite die holders forming the head.
Claims24
A method of forming a manufacture comprising:
- mounting a die in an associated die holder for the production of heads on elongate bodies,
- receiving and holding an elongate body longitudinally in a groove through a top surface of the die,
- forming a head on the elongate body at a recess of one end of the groove,
- press fitting a side surface of the die by contact with an inner surface of a bore or hole in the associated die holder,
- engaging a stop surface of the die with a stop part in the hole or bore of the associated die holder, so as to determine a height of the die in relation to the associated die holder, and
- engaging a recess or protrusion of the die with a corresponding protrusion or recess of the associated die holder, in order to fix angular orientation of the groove relative to the die holder.
