Abstract

Round kneading machines are used to obtain reductions in the cross-section of rods and tubes. The use of the 4-ram machine allows higher reductions for each operating cycle.

Description

Die Erfindung betrifft eine Sattelrundknetmaschine.The invention relates to a rotary saddle kneading machine.

kundknetmaschinen sind Umform-Maschinen, vorzugsweise zum Reduzieren des Querschnittes von Stäben und Rohren. Die Sattelrundknetmaschine ist eine Sonderbauform, sie hat Einrichtungen um die Werkzeuge radial zu öffnen, zusätzlich und in gleicher Richtung wie der Werkzeug-Oszillationshub. Dadurch kann zwischen zwei Enden reduziert werden.Custom kneading machines are forming machines, preferably for reducing of the cross-section of rods and tubes. The rotary saddle kneading machine is a special design, it has facilities to open the tools radially, in addition and in the same way Direction like the tool oscillation stroke. This allows reduced between two ends will.

Sattelrundknetmaschinen sind im Aufbau und in der Wirkungsweise bekannt (Metals Handbook Vol "formling" 8th Edition, 1969, Seite 330 - 346, Am. Soc. for metals, Metals Park, Ohio, 44073).Saddle rotary kneading machines are known in their structure and mode of operation (Metals Handbook Vol "formling" 8th Edition, 1969, pp. 330-346, Am. Soc. For metals, Metals Park, Ohio, 44073).

4-Stösselmaschinen sind ebenfalls bekannt (Firmenschriften der Firma Heinrich Müller, Pforzheim).4-ram machines are also known (company publications of the company Heinrich Müller, Pforzheim).

Alle bisher bekannt gewordenen Sattelhämmermaschinen sind Zweistösselmaschinen. Diese Bauform hat bei hohen Umformquerschnitten technische Nachteile.All previously known saddle hammering machines are two-ram machines. This design has technical disadvantages with large forming cross-sections.

Weil die Werkzeuge einerseits in deren Mitte die Form des zu erzeugenden Durchmessers besitzen müssen, andererseits aber am Ausgangsquerschnitt tangential angreifen müssen, ist das Mass des Reduzierbetrages bei Zweistösselmaschinen begrenzt. Von daher liegt der Erfindung zugrunde, die Vorteile des Rundknetens in der 4-Stössel-Bauweise auf das einstechende Rundkneten zu übertragen.Because, on the one hand, the tools have the shape of the one to be generated in the middle Must have diameter, but on the other hand tangential to the starting cross-section have to attack is the measure of the reduction amount for two-slide machines limited. The invention is therefore based on the advantages of rotary swaging in the 4-ram design to the plunge-cut rotary swaging.

Im Gegensatz zur Zweistösselmaschine ist eine doppelte Anzahl von Kraftangriffsstellen vorhanden. Dies ermöglicht eine höhere Umform-Arbeit. Das bei der Zweistösseltechnik zwangsweise erforderliche kurzzeitige Ovaldrücken der Werkzeuge entfällt bei der 4-Stösseltechnik.In contrast to the two-slide machine, the number of Force application points available. This enables higher forming work. That at the two-pusher technology required brief oval pressures of the tools not applicable with the 4-ram technology.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles beschrieben. Es zeigt: Fig. 1: Frontal-Ansicht der Rundknetmaschine Fig. 2: Längsschnitt der Rundknetmaschine Die 4-Stösselmaschine ist dadurch gekennzeichnet, dass beim Durchlauf der Aussenstössel (3) unter den Rollen (5) alle 4 Aussenstössel und die Werkzeuge (1) zugleich die nach innen gerichtete Radialbewegung ausführen. Die Sattelbewegung wird beim hier dargestellten Ausführungsbeispiel dadurch bewirkt, dass über die Elemente (10, 11, 12) die Aussenstössel (3) axial verschoben werden. Dadurch bewegen sich die Ausgleichsplatten (2) und Werkzeuge (1) radial nach aussen oder innen.The invention is explained below using an exemplary embodiment described. It shows: Fig. 1: Front view of the rotary swaging machine Fig. 2: Longitudinal section of the rotary swaging machine The 4-ram machine is characterized by the fact that the Passage of the outer tappets (3) under the rollers (5) all 4 outer tappets and the Tools (1) perform the inward radial movement at the same time. The saddle movement is effected in the embodiment shown here in that over the Elements (10, 11, 12) the outer tappets (3) are axially displaced. Move thereby the compensating plates (2) and tools (1) radially outwards or inwards.
