Definitions

  • the invention relates to a transmission element according to the preamble of claim 1, also a tool element with the features of the preamble of claim 8.
  • DE 10 2004 055 377 A1 describes a transfer element designated as a distributor device, which serves to forward a mixture of coolants / lubricants which is fed into the transfer element to a tool having at least one geometrically defined cutting edge which serves to form a workpiece to edit.
  • the transfer element is designed such that the medium provided by a common coolant / lubricant supply is divided into partial streams in order to ensure uniform cooling of the various cutting edges.
  • It also has at least two separate channels into which the at least two separate media are separately introduced and which is arranged to forward the at least two separate media separately from a feed end to a delivery end of the delivery member through the at least two channels, each of which media also having a separate channel assigned.
  • the dispensing element is finally designed such that the at least two separate media can be dispensed separately to a tool or the like. What has been said about the separate channels in the supply tube applies correspondingly to the two separate channels in the delivery element.
  • the transmission element variable in its longitudinal extent. It is thus possible to arrange the supply pipe in a distance, seen in the longitudinal direction, to a discharge element.
  • a particularly short construction of the transmission element results when the feed tube and the dispensing element are directly coupled to one another such that the separate channels present in the feed tube and in the dispensing element are in fluid communication with each other such that mixing of the media present in the channels does not occur comes. It is also provided here that the at least two media do not escape via the connection region between supply tube and delivery element. Moreover, it is also possible to form the feed tube and the dispensing element in one piece.
  • the transmission element which is adapted to transmit as a first medium a gas, preferably carbon dioxide or the like and as a second medium, a coolant / lubricant, wherein the first medium can be fed under an overpressure in the transmission element and the second medium is an MMS aerosol.
  • the tool element in a modification of the tool element, it is possible to provide at least two separate channels in the transmission element, which are closed to the outside, so extend completely in the interior of the transmission element. In such a case, therefore, the tool element in no way needs to be tuned to provide a way to pass a fluid. It can therefore be dispensed in this case on the above-mentioned channel section.
  • the tool element has a channel section which leads a medium from the feed end of the feed tube to the discharge end of the discharge element, separate from media flowing within the transfer element.
  • a tool element in which in the clamping section the supply pipe and in the holding portion or in the tool representing portion of the chuck, a discharge element of the transmission element is provided.
  • the discharge end 15 of the supply pipe 1 1 sealingly bears directly on the feed end 25 of the discharge element 19.
  • at least two media are introduced separately into the feed end 13 of the feed pipe 11, they become at least two media discharged at the discharge end 27 of the discharge element 19, wherein they are separated by the channels 7 and 9 in the feed tube 1 1 and through the channels 21 and 23 of the discharge element 19, so that there is no mixing of the at least two media over the entire transport path.
  • At least two fed media can therefore be dispensed separately to a tool 3. Preferably, they are then also forwarded there separately from the shank 5 of the tool 3 to a processing point of the tool 3.
  • the tool 3 is part of a tool element, which is designed here as a chuck 39.
  • the transmission element 1 is characterized by a very simple structure and a flexible design. It has been stated that the supply pipe 11 and the discharge element 19 can be formed directly adjacent to each other or in one piece, that it But it is also possible, through a transfer tube 29, a distance between the supply pipe 1 1 and the discharge element 19, seen in the direction of the central axis 17 to provide.

Abstract

L'invention concerne un élément de transmission (1) pour transférer au moins deux milieux au niveau d'un outil (3) ou similaire pour l'usinage d'une pièce, comprenant un tube d'amenée (11) comportant au moins deux canaux (7, 9), dans lequel lesdits au moins deux milieux peuvent être introduits. L'élément de transmission est conçu pour transférer lesdits au moins deux milieux d'une extrémité d'alimentation (13) à une extrémité de distribution (15) du tube d'amenée (11) à travers lesdits au moins deux canaux (7, 9). L'élément de transmission (1) est caractérisé en ce que lesdits au moins deux canaux (7, 9) du tube d'amenée (11) sont réalisés de manière séparée et sont conçus pour transférer de manière séparée lesdits au moins deux milieux séparés de l'extrémité d'alimentation (13) jusqu'à l'extrémité de distribution (15) du tube d'amenée (11), un canal séparé étant associé à chacun des milieux, et en ce qu'un élément de distribution (19) est prévu, lequel est disposé de préférence de manière concentrique par rapport au tube d'amenée (11) et à distance de celui-ci et lequel comprend au moins deux canaux (21, 23) dans lesquels lesdits au moins deux milieux peuvent être introduits de manière séparée, et lequel est conçu pour transférer de manière séparée lesdits au moins deux milieux d'une extrémité d'alimentation (25) à une extrémité de distribution (29) à travers lesdits au moins deux canaux (21, 23), un canal séparé (21, 23) étant associé à chacun des milieux, l'extrémité de distribution (27) de l'élément de distribution (19) étant réalisée de telle sorte que lesdits au moins deux milieux peuvent être distribués de manière séparée au niveau d'un outil (3) ou similaire.
