  • the claim 1 provides that the work surface of the 00054 tool is irradiated with energy, the 00055 irradiation is carried out in such a way that recesses are produced, 00056 which have raised edge ribs. In this case, 00057 the area close to the surface is melted with 00058 a melt that solidifies at the edge into ribs.
  • the 00059 process can be carried out without problems after heat treatment 00060, for example hardening the blank. This is suitably brought to a toughness corresponding to 00062 in the heat treatment 00061, so that a low material brittleness 00063 is present.
  • This tough core material 00064 rial is then preferably irradiated with a laser, 00065 whereby local surface hardening follows only in the engraving zones and not in the 00066 intermediate areas.

  • the surface area 11 is melted.
  • the 00319 bubbles that are produced are frozen by the sudden solidification, so that roughening occurs.
  • 00321 00322 In the exemplary embodiment shown in FIG. 6, 00323 a steel core surface 11 00324 pretreated according to FIG. 5 was treated with writing 00325 with a focused laser beam. Line-shaped 00326 structures were applied to the surface.
  • the surface material of the 00327 steel body 4 was melted in some areas and 00328 was displaced towards the edge, so that wall-like structures 1032 are formed on both sides of the channel 9, which protrude beyond the 00330 surface 11.

  • 00350 00351 The shape of the grooves, the direction of the grooves and the 00352 arrangement of the grooves can be adapted to the power output profile 00353 of the screwing tool. So the 00354 grooves can form a diamond shape. You can get fish-like in fishbones. But you can also leave 00356 transverse or parallel to the direction of extension of the blades. In contrast to the embossing of surface structures 00358, there are almost no 00359 limits to the shape and course of the grooves, as there are no demolding problems.

Abstract

L'invention concerne un outil à main, se présentant notamment sous la forme d'un tournevis ou d'une lime, comprenant une ou plusieurs surfaces de travail. Ces dernières comportent des parties profilées produites par l'intermédiaire d'évidements qui sont pratiqués au moyen d'un rayonnement à grande énergie et qui présentent des nervures marginales. Ces dernières peuvent être constituées par les bords d'une matière en fusion qui se solidifie instantanément pour former une structure en cuvette.
