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.
Claims20
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 including
- a body with a top surface provided with a through-going groove for receiving and holding an elongate body longitudinally in said groove,
- 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 method of manufacturing nails comprising:
- receiving and holding an elongate body longitudinally in a groove on a top surface of a body,
- forming a head on an elongate body via a recess at one end of the groove,
- press fitting, by contact, a side surface with an inner surface of a bore or hole in an associated die holder,
- engaging a stop surface 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 with a corresponding a contact surface associated with die holder to fix an angular orientation of the groove relative to the die holder.
A die holder comprising:
- a body having at least a top surface part,
- a plurality of holes or bores in the top surface part, wherein each of the plurality of holes or bores has an inner surface configured to receive an associated die and for press fit by contact with a side surface of thereof,
- a stop part located in each hole or bore configured to engage a stop surface of an associated die when being pressed into the hole or bore, so as to fix a height of a top surface of its associated die in relation to the top surface part of the die holder, and
- a protrusion or recess associated with each hole or bore configured to engage with a corresponding contact surface of its associated die so as to fix angular orientation of its associated die relative to the die holder.
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 and including:
- a body with a top surface provided with a through-going groove for receiving and holding an elongate body longitudinally in said groove, 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.
