Definitions

  • the invention relates to a separating device for bar material, profiles, pipes or the like. According to the preamble of claim 1.
  • a circular saw machine for cutting pipes of different diameters generally consists of a work table, feed means, e.g. Transport rollers, with the help of which the workpieces to be cut into one

  • the two- or four-point clamping is first removed, i.e. canceled, and possibly a so-called.
  • Deposition of the saw blade carried out by a small amount in the direction of the workpiece longitudinal axis. On the one hand, this frees the saw blade for its return to the starting position, and on the other hand, the separated part of the workpiece can be removed from the work area by means of transport rollers using manual means.
  • Length are difficult to remove, so that there is a disability of the further supply of new material after a first plan cut has been carried out. This may result in jamming of the bar stock being fed, so that either the two or four point tension cannot be adequately released or that separated remnants get into the transport or guide roller mechanism, which results in a malfunction in the operation of the circular saw machine. In the cases described above, the functionality must then be restored manually.
  • the basic idea of the separating device for bar material according to the invention is that a special device for pushing the workpiece out of the processing space, which is formed by a work table and clamping means for fastening a workpiece, is created.
  • This device has a sword that can be moved into and out of the working space. After it has been moved into the working space, the sword is moved essentially to the longitudinal axis of the workpiece to be cut, taking the workpiece with it.

  • the sword has a wedge shape directed towards the separating gap of the workpiece
  • a partial horizontal movement of the workpiece is already realized when the sword penetrates into the separating gap.
  • This partial horizontal movement enables an easier removal of a saw blade located in the separation gap.
  • the vertical movement of the sword through the opening in the work table into the work space is directed in the opposite direction to and essentially in synchronism with the movement or the return stroke of a cutting tool, for example a saw blade, from the cutting gap.
  • the sword is not only used for pushing out and removing head and remnants or parts of a workpiece cut to length, but at the same time removing residues from the cutting process, e.g. Chips from the work area.
  • the sword on its underside facing the work table can have means for taking away the residues mentioned in the cutting process.
  • These means can e.g. comprise a chip brush or nozzles, with the aid of which compressed air or a flushing liquid reaches the work table in order to remove the residues.

  • a horizontal clamping 8 is used to fasten the workpiece 7 on a work table 9.
  • a device for pushing the workpiece 7 out of the working space AR consists of a sword 11, which in the example shown from below through a slot-shaped opening 13 in the working table 9 into the working space AR is movable.
  • the sword 11 is pivoted into the working space AR by a first drive device 20.
  • a second drive device 30 enables a controlled movement of the sword 11 along the surface or plane of the work table 9, wherein in the example of FIG. 1 when the sword 11 is moved to the right and a workpiece is fed in via corresponding guide means, such as rollers and rails from the left, the separated part of the sword 11

  • the feeding of the sword is selected depending on the direction of the separation process to be carried out. If e.g. the saw blade 3 is lowered towards the workpiece 7, then the sword 11 is inserted from below. In the opposite case, the sword lowers from above and penetrates into the separation gap in order to remove the workpiece 7 from the processing space. Alternatively, the sword 11 can also be inserted laterally into the processing space, which e.g. is useful when using a band saw.

Abstract

L'invention concerne un système d'éjection de parties coupées d'une pièce, qui comprend un élément en forme de lame (11) qui est inséré par glissement ou par pivotement, de manière opposée au sens de travail de l'outil de tronçonnage (4), dans la fente de tronçonnage (TS) de la pièce (7), en passant par une fente (13) ménagée dans la table de travail (9). Après avoir été introduit par glissement ou par pivotement, l'élément en forme de lame (11) est sorti horizontalement de l'espace d'usinage (AR), le long de la surface de la table de travail (9), de manière à entraîner avec lui, la section concernée de la pièce. L'élément en forme de lame (11) effectue ainsi successivement un mouvement sensiblement vertical ou pivotant et finalement un mouvement horizontal pour dégager la table de travail (9). L'élément en forme de lame (11) lui-même peut être pourvu sur sa face orientée en direction de la surface de la table de travail (9), d'éléments permettant d'enlever les résidus d'usinage, par ex. une brosse pour enlever les copeaux. L'ampleur et la direction, notamment du mouvement horizontal de la lame (11) étant réglables, les sections enlevées peuvent être triées, par affectation de parties séparées de la pièce à différentes positions de dépôt, devant ou derrière l'outil de tronçonnage, ce qui permet d'augmenter la rationalisation du processus de fabrication.
