Abstract

A machine for shaping plastic tube walling has one pressure cylinder, this closes pivoting segments and the tube is pressed outwards to the contour of the segments by means of an axial bush. There is only one cylinder, the segmenting tools are simple, the tube is loaded/unloaded simply, the machine is small and can be used for varying sizes according to the forming tools.

Description

Sicken-und Muffenmaschine zum Stauchen von Kunststoffrohren Beschreibung Gegenstand der Erfindung ist eine Sicken-u.Muffen-Stauchmaschine für Kunststoffrohre.Beading and socket machine for upsetting plastic pipes Description The invention relates to a beading and socket upsetting machine for plastic pipes.

Khnliche maschinen gibt es bereits in mehrfachen Ausführungen im Handel.Several versions of similar machines are already commercially available.

Jedoch sind diese Maschinen viel zu aufwendig und teils zu kompliziert.Man verwendet entweder zwei Zylinder für die zweiteiligen Backenwerkzeuge und einen dritten Zylinder zum Stauchen,oder eine andere Version ist z.B. ein Von innen nach außen wirkendes Werkzeug.However, these machines are far too expensive and sometimes too complicated uses either two cylinders for the two-piece jaw tools and one third cylinder for upsetting, or another version is e.g. an inside-out external tool.

hierbei wird zwar nur ein Zylinder verwendet, aber dafür ist das Werkzeug sehr kompliziert.Im Kleinen Innenraum müssen hierbie die einzelnen Segmente mittels Hebel nach außen gedrückt werden,wodurch die Muffe, oder Sicke eingedrückt wird.only one cylinder is used here, but that's what the tool is for very complicated. In the small interior space, the individual segments have to use Lever are pressed outwards, whereby the sleeve or bead is pressed in.

Der Erfindungsgegenstand hebt sich durch seine Einfachheit und vor allem billigere Herstellungsart von den bekannten Ausführungen ab.The subject of the invention stands out for its simplicity and in front all cheaper production method from the known designs.

Er ist dadurch durch folgende Merkmale gekennzeichnet: 1.Es ist nur ein Zylinder erforderlich.It is characterized by the following features: 1. It is only a cylinder required.

2.Die Segmentteilung geht nach außen, und ist leicht herstellbar.2. The segment division goes outwards and is easy to manufacture.

3.Das Rohr kann leicht eingelegt und entnommen werden.3. The tube can be easily inserted and removed.

4.Die Außenmaße werden viel kleiner.4. The external dimensions will be much smaller.

5.Die Maschine kann in gleicher Ausführung für mehrere Rohrgrößen verwendet werden, Hierbei muß lediglich das Werkzeug ausgewechselt werden.5. The machine can be used in the same version for several pipe sizes can be used, here only the tool has to be changed.

Funktion Fig.1 einen Längsschnitt,wobei die untere Hälfte im Einlegezustand, und die obere Hälfte im Spann-bzw.Stauchzustand dsrgestellt ist.Function Fig. 1 a longitudinal section, the lower half in the inserted state, and the upper half is in the tensioned or compressed state.

Fig.2 stellt den Querschnitt dar,wobei der Schnitt in der oberen Hälfte durch die beweglichen Segmente(e) und in der unteren Hälfte durch den Haltering(n) gelegt ist0 Der Zylinder(a) drückt eine Traverse(b,c,) verbunden mit den Klemmarmen(d) nach vorn,und schließt somit die gelenkartigen Semente(e), nachdem vorher das vorgewärmte Kunststoffrohr(f) eingelegt,und mittels Spannbügel(g) festgehalten worden ast, währen durch die Klemmarme die Segmente bereits geschlossen wurden, geht der Hub des Zylinders(a) weiter und drückt im Folgegang die Stauchbuchse(h) nach vorn,wodurch das Kunststoffrohr in die Aushöhlung des Werkzeuges eingestaucht wirdUnmittelbar vorher muß jedoch über eLe Ventil durch den Dorn(i) Preßluft eingedrückt werden.Fig.2 shows the cross section, with the section in the upper half through the movable segments (e) and in the lower half through the retaining ring (n) 0 The cylinder (a) pushes a crossbeam (b, c,) connected to the clamping arms (d) forward, and thus closes the joint-like Semente (e) after the preheated Plastic tube (f) inserted and held in place by means of a clamp (g), while the segments have already been closed by the clamping arms, the stroke of the cylinder (a) then pushes the compression bushing (h) forward, causing the plastic tube is plunged into the cavity of the tool, but must be done immediately beforehand compressed air can be pressed in via the eLe valve through the mandrel (i).

Nach der Abkühlungszeit(die Werkzeuge können wassergekühlt werden)wird der Zylinder wieder zurückgeholt,wobei die Stauchmuffe(Stauchbuchse h) durch Druckfedern zurückgeholt wird,und die Segmente(e) sich ebenfalls mittels Zugfedern selbständig wieder öffnen.Der Haltering(n)ist mittels Arme(o)Fig.2 und Außenrung(p) fest mit dem Gestell(q)verbunden.After the cool down period (the tools can be water-cooled) the cylinder is brought back, the compression sleeve (compression sleeve h) by compression springs is retrieved, and the segments (e) also independently by means of tension springs The retaining ring (n) is fixed with the arms (o) Fig. 2 and the outer stanchion (p) connected to the frame (q).

Die erforderliche Elektroschaltung kann z.B.im Kasten(r), die Hydraulik im Kasten(s)untergebracht werden.The required electrical circuit can e.g. in the box (r), the hydraulics be accommodated in the box (s).

Der Außenring ist mittels Stangen(t) mit der Zylinderhalterung(u) verbunden. Die Maschine kann mit einer Abdeckhaube (v) versehen werden.The outer ring is connected to the cylinder holder (u) by means of rods (t) tied together. The machine can be fitted with a cover (v).
