Description

Es ist eine immer dringender erhobene Forderung, die Materialprüfung auch an Gummi und Kunststoffen bei Kälte und Wärme vorzunehmen. Materials testing is an ever more urgent requirement also to be carried out on rubber and plastics in cold and warm conditions.

Deshalb wurden Prüfmaschinen mit umfangreichen Einrichtungen zur Kühlung und Erwärmung des Versuchsraumes entwickelt, die besonders durch die notwendigen starken Isolierwände sehr schwerfällig und teuer werden.Therefore testing machines were equipped with extensive cooling facilities and heating of the test room developed, especially by the necessary strong insulating walls are very cumbersome and expensive.

Gegenstand der Erfindung ist eine Klimakammer zur Aufnahme der zwischen den Einspannvorrichtungen von Prüfmaschinen, insbesondere - Zerreißmaschinen, anzuordnenden, vorzugsweise aus Gummi oder Kunststoffen bestehenden Prüflinge. The invention relates to a climatic chamber for receiving the between the clamping devices of testing machines, in particular - tearing machines, to be arranged, preferably made of rubber or plastics.

Die Klimakammer gemäß der Erfindung ist trotz geringer Abmessungen einwandfrei isoliert, billig in der Herstellung und außerdem durchsichtig. Sie ist oben und unten offen und wird in der Art einer Thermosflasche aus zwei konzentrischen, oben und unten verschmolzenen und evakuierten Glasröhren G1 und G2 hergestellt (Abb. I). Die Endöffnungen werden zum Durchtritt der Einspann- und Kraftmeßeinrichtungen sowie zur Temperierung und Befeuchtung benutzt und im übrigen mit Isoliermaterial E abgeschlossen; Die Führung der Spannköpfe im Innern des inneren Rohres kann z. B. durch eine halbkreisförmig gebogene Metallschiene M und ein Querhaupt Q erfolgen (Abb. 2). Die Rotation der SpannrollenR bei der Ringprüfung an Gummi und Kunststoffen kann durch eine an die Schiene M angebaute Zahnstange Z bewirkt werden.The climatic chamber according to the invention is small despite its small dimensions perfectly insulated, cheap to manufacture and also transparent. she is open at the top and bottom and is made up of two concentric, top and bottom fused and evacuated glass tubes G1 and G2 (Fig. I). The end openings become the passage of the clamping and force measuring devices as well as used for temperature control and humidification and otherwise with insulating material E completed; The leadership of the clamping heads inside the inner tube can, for. B. be done by a semicircular curved metal rail M and a cross head Q. (Fig. 2). The rotation of the tensioning pulleysR during the ring test on rubber and plastics can be effected by a toothed rack Z attached to the rail M.

Zum Schutz des evakuierten Glasrohres kann innen und außen ein Hartglasrohr, Kunststoffrohr oder etwas ähnliches eingebaut werden. To protect the evacuated glass tube, a hard glass tube, Plastic pipe or something similar can be installed.

PATENTANSPRSCIIE: I. Klimakammer zur Aufnahme der zwischen den Einspannvorrichtungen von Prüfmaschinen, insbesondere Zer,rei,ßmaschitnen, anzuordnenden, vorzugsweise aus Gummi oder Kunststoffen bestehenden Prüflinge, dadurch gekennzeichnet, daß die Wandung der an beiden Enden offenen, aber verschließbaren Kammer aus zwei konzentrischen, oben und unten verschmolzenen und evakuierten zylindrischen Glasröhren besteht. PATENT APPLICATION: I. Climatic chamber to accommodate the between the clamping devices to be arranged by testing machines, in particular cutting, tearing, ßmaschitnen, preferably Test specimens made of rubber or plastics, characterized in that the Wall of the chamber, which is open at both ends but can be closed, consists of two concentric, consists of fused and evacuated cylindrical glass tubes above and below.
