Definitions

  • the present invention relates to a clamping device for making nails, comprising a die holder which is mountable in a nail-making machine and a hard-metal die disposed in said die holder, the hard-metal die having a clamping part which together with a corresponding clamping part of a complementary clamping device holds a nail during the manufacture thereof.
  • Clamping devices of the above-mentioned kind are previously known. They are provided in pairs in a nail-making machine and hold the nail while a head is being formed and the nail is cut off from a metal wire.
  • the known clamping devices comprise a die holder provided with a recess, in which a hard metal die has been mounted by soldering. The reason why the entire clamping device is not made of hard metal is the high material costs. Although the clamping parts are made of hard metal they wear out after some time of use, and the whole clamping device will then be discarded and replaced by a new one, since the cost of removing the die and mounting a new die in the die holder will not be less than that of replacing the whole clamping device and since the tensile properties of the die holder become impaired.
  • clamping devices shown in the figures are used in pairs, as shown in Figure 4, in a nail-making machine to clamp a wire while a head is being formed at the open end of the wire by means of a punch and the wire is cut to the length of the nail by cutting tools working in pairs.
  • Each of the two clamping devices which are of essen­tially the same shape, comprises a die holder 1 intended to be mounted in the nail-making machine, and a hard-metal die 2, which is detachably mounted in the die holder.
  • the die holder 1 which is made of steel, has a parallel-trapezoidal cross section and is provided with a recess in the form of a drilled hole 3 at one end.
  • the circum­ference of the drilled hole 3 is smaller than the circum­ ference of a circle, so that the drilled hole opens at said end along two parallel edges 4 and 5, the distance between which is considerably smaller than and preferably around two fifths of the diameter of the drilled hole.
  • the edges 4, 5 delimit parallel surfaces 6 and 7 on the die holder 1, the parallel surfaces connecting on to bevels 8 and 9.
  • a smaller drilled hole 10 parallel with the drilled hole 3 but of a smaller diameter than the drilled hole is connected with the drilled hole 3 by means of a through slot 11.
  • a through hole 12 intersects the slot 11 and is provided, on one side of the slot, with a thread 13.
  • a bolt 14 is inserted in the drilled hole 12 and presses the two tool portions 1a and 1b on both sides of the slot against each other on tightening, since said portions are flexible.
  • the die 2 is substantially cylindrical and has a diameter which is slightly smaller than the diameter of the drilled hole 3. Its length corresponds to the length of the drilled hole 3.
  • the die 2 is formed with three plane surfaces in which clamping parts in the form of clamping grooves 15 are provided.
  • Each clamping groove comprises a semi-cylindrical portion 16 with a plurality of annular slots 17, and a semi-frustoconical portion 18. All the clamping grooves 15 can be identical or of different dimensions adapted to different nail sizes and shapes.
  • the clamping grooves 15 can be less or more than three in number and are suitably evenly distributed over the circumference of the die.
  • the die 2 fits the drilled hole 3 into which it is inserted in the way shown in Figures 1 and 4 and is turnable 360° within the drilled hole.
  • the die is lockable in any position in the drilled hole by tightening the bolt 14 which presses the portions 1a and 1b against each other.
  • Figure 4 shows two clamping devices, at least one of which is slidable along its longitudinal axis towards and away from the other clamping device.
  • two identical clamping parts 15 on the two dies 2 bearing on each other form a circular groove 19, the portions 16 of which are intended to clamp a wire (not shown) from which a nail is to be made, and the portions 18 of which are intended to guide the wire fed to the clamping devices.
  • a nail head is intended to be formed from the wire at the open end thereof when a punch (not shown) is struck onto said end in the longitudinal direction of the wire.
