Definitions

  • This invention provides a new method of shortening non-round profiles in similar manner to existing pipe cutters for round pipes.
  • the existing pipe cutters make use of a wedge-shaped cutting wheel of hardened steel which cuts into the pipe all the way around. After a number of revolutions at a constant pressing force the pipe is cut through.
  • the cutting force of the pipe cutter is supported here on the pipe wall diametrically opposite the position of the cutting wheel.
  • a pipe cutter can cut pipes of different size by means of the adjustable cutting wheel.
  • a pipe cutter has the advantage that it is quicker than sawing and that no external burrs are formed. A finishing process is therefore not usually necessary. An additional favourable circumstance is that no shavings are generated.
  • the pipe cutter can only cut round pipes.
  • the profile cutting tool is based on the existing pipe cutter. Just as the existing pipe cutter, the profile cutting tool has a wedge-shaped cutting wheel. Where in the case of the pipe cutter the guiding and support run along the outer side of the pipe diametrically opposite the cutting wheel, the guiding of the profile cutting tool follows a cam track which is adapted to the shape of the profile.
  • the profile for cutting is placed in the profile holder.
  • a recess in the form of the profile This centres the profile and holds it in place.
  • the holder has a simple locking provision for fixing the profile.
  • Located around the profile holder is an annular rotating disc. Between the rotating disc and the profile holder there is a bearing whereby the two parts can rotate relative to each other.
  • a shaft Present at a point on the rotating disc is a shaft, parallel to the profile axis, which connects both the cutting wheel and the travelling roller and the handle. The movements made by the travelling roller are in this way transmitted to the cutting wheel, which then follows the profile precisely.
  • the travelling roller follows a cam track which is derived from the shape of the profile.
  • the cam track is formed integrally with the profile holder.
  • the cutting wheel can be moved along the profile using the handle. Rotating the handle about its longitudinal axis makes it possible to adjust the depth of the cutting wheel by means of a screw adjustment. This makes it possible to cut through the material uniformly.
  • the pressure on the profile is in this way also limited to a minimum, whereby undesired and excessive bending of the profile wall is prevented.
  • Fig. 1 shows a three-dimensional view of the device.
  • Fig. 2 shows a front view of fig. 1.
  • Fig. 3 and fig. 4 show variations of the position of cutting mechanism 3-10.
  • Fig. 5 shows a cross-section through fig. 2.
  • Fig. 2 shows a specific profile 1 in a profile holder 2.
  • the profile holder fixes the profile.
  • Shown around profile holder 2 is a bearing 3 which connects profile holder 2 to a rotating disc 4.
  • Rotating disc 4 and profile holder 2 can rotate relative to each other.
  • a guide arm 6 and a cutting arm 7 are mounted on rotating disc 4 by means of a shaft 5.
  • Guide arm 6 and cutting arm 7 can rotate around shaft 5.
  • Rotating disc 4 can be rotated by means of a handle 1 1.
  • a travelling roller 8 on the outer end of guide arm 6 will follow a cam track 9.
  • Cam track 9 is derived from the shape of profile 1.
  • Cam track 9 and profile holder 2 form one whole.
  • the movement of travelling roller 8 causes a cutting wheel 10, which is coupled to travelling roller 8, to run along the outer side of profile 1.
  • Cam track 9 ensures that pressure is exerted continuously on profile 1 by cutting wheel 10 during rotation of rotating disc 4.
  • Fig. 3 and fig. 4 show different positions during this rotation. It can be seen here that the path of travelling roller 8 ensures that cutting wheel 10 follows the outer side of profile 1 in different positions.

Abstract

L'invention se rapporte à un dispositif qui fournit un nouveau procédé permettant de raccourcir des profilés non ronds de manière similaire à celle des coupe-tubes existants pour des tuyaux ronds. Le dispositif comprend un disque rotatif qui tourne autour du profilé, et un chemin de came qui est dérivé de la forme du profilé. Ces deux éléments se trouvent plus ou moins concentriquement autour du profilé pour permettre sa coupe. La roulette de coupe, le galet d'entraînement et la poignée sont raccordés à un endroit sur le disque rotatif au moyen d'un arbre autour duquel ils peuvent tourner. Les mouvements réalisés par le galet d'entraînement sont, de cette manière, transmis à la roulette de coupe qui, ensuite, suit avec précision les contours du profilé. Le galet d'entraînement suit le chemin de came susmentionné. Le dispositif comprend un réglage avec lequel la position radiale de la roulette de coupe peut être ajustée davantage vers l'intérieur ou vers l'extérieur. La roulette de coupe peut ainsi effectuer par pression une coupe de plus en plus profonde tout autour du profilé et s'enfonçant dans ce dernier pour réaliser sa coupe. De cette manière, il est possible de couper des profilés sur site sans trop d'efforts. En outre, aucun copeau n'est produit.
