Definitions

  • the invention relates to a method for producing a through-hole in a metallic body, which has at least one curved surface, by means of a lifting movement.
  • HGSS high-speed shear cutting
  • This document discloses a method for producing profile parts by separating profile bars.
  • the profile bar is clamped in a tool between two active parts, wherein the facing support side of the active parts are designed in the form of dies, in each of which the shape of the profile to be machined is recessed.
  • the separation takes place adiabatically at a very high impact speed of the cutting punch, wherein the force is introduced via the plunger to an active part.
  • the separation or pressing is generally carried out at a speed in the range of 0.5 to 20 m / s, preferably in the range of 10 to 40 m / s, and particularly preferably in the range of 10 to 20 m / s, which according to this document reaches the adiabatic state from 10 m / s.
  • the invention is therefore based on the object to improve the method of the type mentioned above such that the metallic body can be produced with the highest precision and also at a significantly increased speed.
  • This object is achieved in a method of the type mentioned in that the through hole by means of high-speed cutting (HGSS) takes place.
  • HGSS high-speed cutting
  • Pieces to produce an adiabatic state by means of a lifting movement which is so precisely adjustable that no or hardly any post-processing is necessary. Furthermore, it can be provided that the punching also takes place from the curved surface.
  • the high-speed shear cutting with a ratio of hole diameter D to a metal thickness s of less than 1, 5 is performed.
  • the cross section of the metallic body is triangular, has at least one rounded corner and the through hole extends from the at least one curved corner of transverse to the connecting line of the two other corners.
  • This new inventive method for the production of through holes is versatile in elevated or curved materials.
  • the sliding block is provided with a blind hole according to one of the methods for the production of blind holes according to the simultaneously filed and pending patent application (filed on 05 February 2013).
  • a spring-loaded ball which is of course caulked at the boarding edge, so that it can be held in the blind hole.
  • FIGS. 1 and 2 show a flowchart for the production of the through hole and a further finishing for a sliding block with blind hole.
  • the production or the method for producing a through hole 10 in a metallic sliding block 12 in this case, which naturally has a curved surface, will now be described with reference to FIGS. 1 and 2. It is again pointed out that the description of a sliding block is merely an example, since this method according to the invention can of course also be used for other metallic bodies with curved surfaces.
  • this through hole 10 is performed by means of a lifting movement of a punch 1 1, which is a high-speed shear cutting, starting from the highest elevation of the curved surface of the sliding block 12, is.
  • the punched out material is then fed to a collection point.
  • the through hole 10 can be made with a hole diameter D of 6.9 mm to 7.5 mm and a material thickness s of also 6.9 mm to 7.5 mm. In this method was at a material thickness s of 7.3 mm

Abstract

L'invention concerne un procédé de réalisation d'un trou débouchant (10) dans un corps métallique (12), qui présente au moins une surface incurvée, par un mouvement de va-et-vient, le trou débouchant (10) étant réalisé par cisaillage à grande vitesse (high speed shearing cut).
