Definitions

  • the invention relates to a nail beating jaw for machines for nail production, consisting of an elongated, prismatic base body with a trapezoidal cross section, which has at one end one or more clamping grooves arranged symmetrically to the cross section, each of which merges into a semi-conical recess, the clamping grooves being in one in one Recess of the base body arranged insert are incorporated.
  • Such nail flap jaws are used in pairs in machines where wire is formed into nails. They are arranged so that the clamping grooves are opposite one another. In the course of the workflow, the nailing jaws are closed or opened. In the closed state, the inserted wire is clamped through the tension grooves. The semi-conical recess adjoining the clamping groove serves for better feeding of the wire. In the clamped state, the nail head is then pressed up and the nail is then cut off. For better clamping of the wire, the clamping groove is profiled, for example, with semicircular transverse grooves.
  • the wear-resistant insert is soldered into a corresponding recess in the tool.
  • the cost of such a tool is due to a very complex manufacturing process compared to a nail hammer made entirely of steel much higher.
  • the service life of such a nail hammer jaw equipped with hard metal is at best about five times as long as that of a steel nail hammer jaw. In many cases, however, there may be a premature failure of a hard metal-tipped nail hammer jaw due to cracks due to the soldering stress in the soldered connection.
  • DD-PS 40 525 describes a nail beating jaw made of an elongated, prism-shaped base body with a trapezoidal cross-section with a recess at one end into which a hexagonal insert can be implemented and replaced.
  • the clamping grooves are incorporated into the lateral surfaces of the hexagonal insert.
  • the insert is only fixed in the base body by a plate fastened with screws. As a result, the attachment of the insert in the base body is inadequate and it comes in particular with movable nailing jaws that work at a frequency of about 1000 strokes / min in the smallest game in the recording for the early destruction of the support for use.
  • the insert is cube-shaped, each with a vertically running clamping groove in two adjoining lateral surfaces and with a horizontally running clamping groove in a further lateral surface. This way and In this way, the notch effect is reduced and such an insert is particularly suitable for heavy loads in nail production.
  • the clamping slot runs parallel to a side surface of the base body. In this way it is achieved that the slot runs outside the semi-conical wire feed and still ensures good clamping of the hard metal insert.
  • FIG. 1 shows a nailing jaw according to the invention, consisting of an elongated, prism-shaped base body -1- made of steel.
  • the side faces of the base holder are inclined at 15 ° to one another, so that the base body has a trapezoidal cross section.
  • the base body -1- has a recess for receiving a cube-shaped insert -2- made of hard metal.
  • the recess is designed so that the insert -2- protrudes slightly on the front and top surface of the base body -1-.
  • On the front side of the insert -2- you can see the central, vertical clamping groove -5- with a semicircular cross-section for clamping the wire.
  • the base body -1- has a lengthwise beginning, the recess for the insert -2- penetrating slot -3-, so that two resilient sections of the base body -1- are formed, which can be clamped against the insert -2- by a clamping screw -4-.
  • the slot -3- runs eccentrically parallel to a side surface of the base body -1- so that it does not pass through the semi-conical recess -6- for the wire inlet. This ensures problem-free wire feeding.
  • the clamping screw -4- is arranged perpendicular to the slot -3-.
  • FIG. 2 shows the hard metal insert for the nail beating jaw according to FIG. 1 in an enlarged view.
  • a vertical clamping groove -5- with a semicircular cross-section is worked into the middle of each lateral surface.
  • the clamping grooves are provided with a cross profile. In this way, the insert -2- can be used four times.
  • FIG. 3 shows a further variant of a cutting insert -2- for the nail beating jaw according to FIG. 1.
  • the insert on two adjacent lateral surfaces each has a centrally arranged, vertically extending clamping groove -5-, while a further lateral surface with a centrally arranged, horizontal clamping groove -5- is provided.
  • the fourth lateral surface can also be provided with a horizontally running clamping groove -5-.
