Definitions

  • Tool in particular screwing tool
  • the invention relates to a tool, in particular screwing, with a drive body made of a first material, in particular steel, which has a Drehmomenteinbringzone and a driven body made of a second material, which output body has an output profile.
  • Such screwing tools are known in the art.

  • the output body is usually made of a different material.
  • the invention particularly relates to such screwing tools which engage an outer profile of a screw head.
  • the invention thus relates in particular to open-end wrenches, ring spanners, socket wrenches, nuts, but also pliers such as Englishman, combination pliers or water pump pliers.
  • the erenkopfangriffs behavior ie the output profile consists of a common tool steel. If such a stainless steel existing output profile of the stainless steel head of a stainless steel screw or a stainless steel nut is rotated, so inevitably rubs steel from the surface of the output profile and attaches to the stainless steel surface of the screw head or nut head.
  • This steel which is usually not rustproof, can be rusting there if weather conditions permit.
  • the invention is therefore based on the object, a generic screw, which is able to transfer high torques on a screw head or a nut with a long service life, further develop to the effect that the foreign rust problem in the use of such a tool on stainless steel nuts or screw heads counteracted.

  • the output body may in a development of the invention, which has independent character, also consist of a material which is harder than the drive body.
  • the drive body with which the torque is applied and transmitted in a radial direction or in an axial direction, can thus be made of a material which has nothing to do with the torque input into the screw head or into the nut. Only the region of the screwing tool that is directly concerned with the torque output is made of a harder material and in particular of stainless steel.
  • the screwing tool according to the invention has at least two torque output surfaces aligned with each other. These surfaces engage corresponding surfaces of a screw head or a nut.
  • the screw head or the nut has a hexagonal cross-section.
  • the torque output surfaces of the output profile engage on two opposite surfaces of the screw head or nut profile.

  • the insert part can be glued, welded or soldered to the mouth of the open-end wrench body (drive body) surrounding it. It can also be provided a positive connection.
  • the insert can also be fitted and retained in the receiving opening by shrinking and subsequent expansion.
  • the insert consists of a sleeve. This sleeve can form a polygonal socket, in particular a hexagon socket or a réellezwölfkant.
  • the outer wall of the sleeve is non-circular, so that a positive torque transmission can take place.
  • the outer wall of the insert has a toothing.
  • the screwing tool is a ratchet spanner.
  • a ratchet wrench of this type has one eye.

  • This ratchet ring has a polygonal contour.
  • the entire ratchet ring is made of stainless steel.
  • the eye forming drive body is made of non-stainless steel.

  • the existing stainless steel output body form the shape of a sleeve. It may be a polygonal sleeve which is inserted in a corresponding polygonal opening of the nut. This sleeve can also be made of a stamped and bent part. Again, there is the eye forming drive body made of stainless steel.

  • Pliers have two pliers arms that intersect in the area of a trade.
  • the pliers arms form one-sided gripping arms which can be moved apart or away from one another.

  • the power of the laser or electron beam is sufficiently large to melt the near-surface area of the irradiated zone.
  • the melt which is located only on a small area of the surface, migrates towards the edge and solidifies there to a rib.
