Definitions

  • the invention relates to a device for cutting a plastic profile to length with a base for lowering the plastic profile and with a slide for holding a knife, which can be moved perpendicularly to the longitudinal axis of the clamped plastic profile and can be driven with the aid of a feed drive.
  • the U-shaped carrier is part of a slide which is guided perpendicular to the longitudinal axis of the plastic profile to be cut to length and perpendicular to a support which receives this plastic profile in a manner that can be cut and which can be adjusted along the guide by means of a lifting cylinder.
  • a disadvantage of this known cutting device for cutting plastic profiles to length is that, despite the clamping device for the knife, the cutting length is limited because the knife length which necessarily increases with the cutting length requires increasingly thicker knife blades as a result of comparatively high clamping forces.
  • the knife must be moved back to its starting position after each cutting stroke, so that the the idle stroke required between the working strokes adversely affects the achievable cutting frequency and, depending on this, the smallest possible cutting length and the overall length of the device.
  • the cutting device with the extruded profile strand must not only be moved during the working stroke but also during the idle stroke before the device can be moved back to its starting position against the extruding direction.
  • the invention is therefore based on the object of designing a device for cutting a plastic profile of the type described at the outset in such a way that any cutting length with the same cutting quality can be ensured with a comparatively low construction effort.
  • the cutting frequency should be increased.
  • the invention solves this problem in that the knife consists of a knife disc which is rotatably mounted about an axis parallel to the longitudinal axis of the clamped plastic profile in the slide guided parallel to the base.
  • the design of the knife as a rotatably mounted knife disc which is moved perpendicular to the longitudinal axis of the plastic profile clamped against the base with the aid of the slide that runs parallel to the base, results in essentially constant cutting conditions regardless of the length of the profile extension in the feed direction of the slide, because it all that matters is the length of engagement of the circular cutting edge and thus the extent of the plastic profile perpendicular to the base.
  • the inherent strength of the correspondingly clamped knife disc is therefore sufficient for a stable cut, especially since the rotary movement of the knife disc supports the exact cut.
  • the knife disc can cut through the plastic profile in both directions of advance of the slide, so that empty strokes between the individual Working strokes of the feed drive are omitted, which has an advantageous effect on the cutting frequency that can be achieved and thus on the shortest possible length of cut to a given conveying speed of the plastic profile.
  • the cutter disc Although it is fundamentally possible to roll the cutter disc on the base that holds the plastic profile, there are more favorable cutting conditions if the cutter disc engages in a guide slot provided in the base, because in this case the complete cutting of the profile strand also occurs in the support area the pad is secured under all circumstances and the knife edge cannot wear out on the base.
  • the guide groove can take over the lateral guidance of the cutter disc, which allows the use of thinner cutter discs without reducing the cutting quality.
  • the rotational movement of the cutter disc is determined by the frictional forces between the cutter disc and the plastic profile to be cut to length.
  • the cutter disc can also be driven in order to increase the relative speed between the cutter disc and the profile strand in the circumferential direction of the cutter disc. Since the relative speed between the cutter disc and the profile strand depends on the feed speed of the carriage carrying the cutter disc, it is advisable to drive the cutter disc as a function of the feed speed of the feed drive for the carriage. If this dependency is ensured by a mechanical drive connection, this results in particularly simple design conditions, since the reversal of the direction of rotation of the cutter disc is also taken into account when changing the feed direction of the slide.
  • the device shown for cutting a plastic profile 1 has a base 2 for the plastic profile 1 to be cut to length, which can be clamped down in a manner known per se via holding-down means against the base 2.
  • a guide rail 3 for a slide 4 is provided at a distance above the base 2, which can be moved along the guide rail 3 with the aid of a feed drive (not shown for reasons of clarity).
  • An axis 5 is rotatably mounted in the slide 4, which axis runs parallel to the longitudinal axis of the plastic profile 1 and carries a clamping head 6 for receiving a knife disk 7.
  • This cutter disk 7 engages with its cutting edge 8 in a guide slot 9, as can be seen in particular in FIG. 2.
  • the base 2 and the guide rail 3 with the slide 4 are accommodated in a common frame which can be moved along in the longitudinal direction of the plastic profile 1 during a cut in order to be moved back into the starting position after the plastic profile 1 has been severed.
  • the knife disk 7 reaches the area of the plastic profile 1 and cuts through it, while the knife disk 7 executes a rotary movement. Since in the illustrated embodiment the cutter disc 7 is not connected to a drive, a rotary movement of the cutter disc arises due to the frictional forces that occur between the plastic profile 1 and that in the plastic profile 1 according to FIG Carriage feed engaging blade 7. After the knife disc 7 has emerged from the kerf of the plastic profile 1, the frame with the support 2 and the guide rail 3 for the slide 4 can be moved back into the starting position against the conveying direction of the plastic profile 1 in order to initiate a new cutting process, but with the opposite direction of cutting.
  • the cutter disc 7 could be driven ahead of a free rolling movement in order to be able to use the effect of a pulling cut to advantage.
  • the knife disk drive required for this can be derived from the feed drive for the slide 4, which entails a constraint between the peripheral speed of the knife disk 7 and the feed speed of the slide 4.
  • the device according to the invention results in a considerable design advantage because the device according to the invention can be arranged together with the saw on a common frame which is moved with the profile strand via a corresponding feed drive during the cutting process, so that only the saw or the Device for the separation process according to the invention is to be controlled.

Abstract

La présente invention concerne un dispositif pour tronçonner un profilé en plastique (1), comprenant une base (2) qui sert à appliquer une faible tension au profilé en plastique (1), et un coulisseau (4) qui est guidé pour pouvoir se déplacer perpendiculairement à l'axe longitudinal du profilé en plastique (1) soumis à la faible tension, peut être entraîné par un entraînement d'avancement, et sert à prendre en charge un élément de découpe. Pour rendre la construction du dispositif particulièrement avantageuse, l'élément de découpe est un disque de découpe (7) qui est monté pour pouvoir tourner autour d'un axe (5) parallèle à l'axe longitudinal du profilé en plastique (1) soumis à la faible tension, dans le coulisseau (4) guidé parallèlement à la base (2).
