Abstract

See full text

A die (1) for mounting in an associated die holder (20) for the production of heads on elongate bodies such as nails or screws. The die has a body (2) with a top surface (3) provided with a through-going groove (4) for receiving and holding an elongate body longitudinally in said groove. Furthermore, the die has a recess (5) on one side merging into the groove (4) at one end of the groove (4) suitable for forming the head of a nail or screw. The die has a side surface portion, e.g. conical, shaped for press fit by contact with a corresponding inner surface portion of a bore or hole (30) in the associated die holder. Further, a second side surface portion (9), e.g. a plane portion, of the die serves to engage with a corresponding inner surface portion of the bore or hole of the die holder. Hereby, it is ensured, that angular orientation of the groove (4) is fixed relative to the die holder (20), and it has been proven that the two different side surface portions of the die, e.g. with a conical portion and a plane portion, provides an efficient press fit which ensures a long lifetime of the die. Further, the die is very simple to mount in the die holder, e.g. by hand, and it is simple to eject by a tool. Thus, altogether a highly efficient nail production can be obtained with such die and die holder system.
