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.
Claims13
A method for manufacturing a head on an elongate body comprising:
- receiving an elongate body in to a die for mounting in an associated die holder for the production of heads on elongate bodies, the die having a rounded exterior, the die further including
- a body with a top surface provided with a through-going groove for receiving and holding an elongate body longitudinally in said groove, wherein the groove is perpendicular or substantially perpendicular to a central longitudinal axis through the body of the die from the top surface to a bottom part of the body of the die,
- a recess at one end of the groove suitable for forming the head on the elongate body,
- a side surface shaped for press fit by contact with an inner surface of a bore or hole in the associated die holder,
- a stop surface for engaging 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
- a recess or protrusion serving to engage with a corresponding surface associated with the die holder, in order to fix angular orientation of the groove relative to the die holder;
- and
- forming a nail from the elongate body received into the die.
A manufacture comprising:
- a die for mounting in an associated die holder for the production of heads on elongate bodies, the die having a rounded exterior, the die further including:
- a body with a top surface provided with a through-going groove for receiving and holding an elongate body longitudinally in said groove, wherein the groove is perpendicular or substantially perpendicular to a central longitudinal axis through the body of the die from the top surface to a bottom part of the body of the die,
- a recess at one end of the groove configured to form a head on the elongate body,
- a side surface shaped for press fit by contact with an inner surface of a bore or hole in the associated die holder,
- a stop surface for engaging with a stop part in the hole or bore of the associated die holder, so as to fix a height of the die in relation to the associated die holder, and
- a recess or protrusion configured to engage a corresponding contact surface associated with the die holder to fix angular orientation of the groove relative to the die holder.
