Abstract

Facilitates the cutting of continuous lengths of foamed materials with a right-angled cross-section by raising and lowering the material relative to the cutting edge during a horizontal slitting operation. The "saw edge" used is pref. one which can cut its way free perpendicularly to the main direction of cutting, and can be a heated filament, a crossed band, etc.

Description

Verfahren zum kontinuierlichen Schneiden eines Profils mit rechteckigem Querschnitt und beliebiger Form des Längsschnittes in Schaumstoff oder leichten Materialien Beschreibung: Es handelt sich bei der Erfindung um ein Verfahren, daß es erlaubt, ein Profil in kontinuierlichen Schnitt auf Schaumstoff oder leichten Materialien zu bringen, dessen Querschnitt eine rechteckige Form hat und dessen Längsschnitt von beliebiger Form ist.Process for continuously cutting a profile with rectangular Cross-section and any shape of the longitudinal cut in foam or light Materials Description: The invention is a process that it allows a profile in continuous cut on foam or lightweight Bring materials whose cross-section has a rectangular shape and whose Longitudinal section is of any shape.

Bin Beispiel solcher Formen bringt Zeichnung 1 Nach den bis jetzt bekannten Verfahren werden solche Form teile durch formschäumen gewonnen.An example of such forms is shown in drawing 1 according to the up to now known processes, such molded parts are obtained by foam molding.

Eine andere Möglichkeit ist, daß Material auf zuspalten und enschließlich die Sinzelteile Stück für Stück an einer Schablone mit Hand abzufahren und so die gewünschten normen aus zuschneiden.Another possibility is to split the material up and finally to move the individual parts piece by piece on a template by hand and so the cut out the required standards.

Die Nachteile dieser Verfahren aind folgende: Das erste Verfahren eignet sich nicht für kleine Stückzahlen, da die Formen zu teuer sind. Außerdem sind die Anschaffungskosten einer solchen Formschäumungsiiaschine sehr hoch.The disadvantages of these methods are as follows: The first method is not suitable for small quantities because the molds are too expensive. aside from that the acquisition costs of such a foam molding machine are very high.

Die Nachteile des zweiten Verfahrens sind: Es gibt geringe Leistungen, ist nicht von ungelerntem Personal auszuführen und die Genauigkeit des Fertigungteils hängt von der Geschicklichkeit des Bedienungspersonal ab Den jetzigem Stand der Technik Profile auszuschneiden, zu verbessern hat sich das folgende Verfahren zum Ziel gemacht0 Der Grundgedanke ist folgender: Ein Materialblock wird horizontal aufgespalten und während des Aufspaltvorganges wird das Material relativ zum Messer in einer Richtung bewegt, die senkrecht zur Spaltrichtung ist0 Die senkrecht zur Spaltrichtung stattfindende Bewegung des Materials relativ zum Messer, wird durch eine vorgegebene Kurve bestimmt, So Zeichnung 2 Das Verfahren wird erst dann möglich, wenn das " Säge" band ", welche das Material auftrennt, so geartet ist, daß es sich senkrecht zur Schnittrichtung (Aufspalten) freischneiden kann, Um dies zu erreichen, gibt es mehrere Möglichkeiten0 Einige davon seien hier genannt: Geschränktes Sägeband, Glühdraht, gedrilltes Rundsägeband etc.The disadvantages of the second method are: there are low benefits, is not to be carried out by unskilled personnel and the accuracy of the production part depends on the skill of the operator The current one State of the art To cut out profiles, the following process has improved Aimed at 0 The basic idea is as follows: A block of material becomes horizontal split and during the splitting process the material is relative to the knife moved in a direction perpendicular to the cleavage direction0 the perpendicular to the Movement of the material relative to the knife, which takes place in the direction of the splitting, is determined by a given curve is determined, see drawing 2 The procedure is only possible when the "saw" that cuts the material is such that it can can cut free perpendicular to the cutting direction (splitting), in order to achieve this, there are several possibilities0 Some of them are mentioned here: Set saw band, Glow wire, twisted circular saw band etc.

Die Vorteile des Verfahrens liegen darin, daß erhebliche Leistungen erzielt werden können, daß kontinuierlich geschnitten werden kann, die Einzelteiltoleranzen sehr klein sind und keine Arbeitsunterbrechung stattfindet, da e ean kontinuierlicher Schnitt erfolgt.The advantages of the process are that it provides considerable benefits can be achieved that can be cut continuously, the individual part tolerances are very small and there is no interruption to work, since it is more continuous Cut takes place.
