Description

EXZE@TER-HYDRA@LIKPRESSE EXZE @ TER-HYDRA @ LIKPRESSE

Beschreibung uf der Exzenterwelle E läuft die mit der Exzenterwelle verspannte Exzenterbuchse B. Darauf läuft das Pleuel P. Dort, wo üblicherweise das Gewinde fiir den Pleuelzapfen ist, befindet sich ein doppeltwirksamer Hydraulikzylinder P 2. Description uf the eccentric shaft E runs with the eccentric shaft Strained eccentric bushing B. The connecting rod P runs on it, where the There is a double-acting hydraulic cylinder P 2.

In ihm Läuft der Kolben K mit der Kelbenstange KS.The piston K runs in it with the Kelben rod KS.

KK ist eine Kelbenstangenklemmung, S der Stößel, F 2 die Führungsleisten derselben.KK is a Kelben rod clamp, S the ram, F 2 the guide strips the same.

Die Verstellune des Stößels s erfolgt durch das Einbringen einer Hydraulikflüssigkeit ender Paste über Z t bzw. 2 2. Bei Erreichen der gewünschten Höhe werden Z 1 und Z 2 mit einem definierten Druck über ein regelbares Überlastventil beaufschlagt Seil diese Presse jetzt als Hydraulikpresse genutzt werden, wird die Ilubverstellung auf den Hub im oberen Tstpunkt gefahren und Z 1 und Z 2 wechselseitig mit Druck beaufschlagt. Semit vereinigt dieses Pleuel die Verteile einer schnelllaufenden Exzenterpresse und einer langsamen Hydraulikpresse mit linearem Kraftverlauf für Zieharbeiten.The ram is adjusted by introducing a hydraulic fluid ender paste over Z t or 2 2. When the desired height is reached, Z 1 and A defined pressure is applied to Z 2 via a controllable overload valve Rope this press can now be used as a hydraulic press, the Ilubverstellung moved to the stroke in the upper Tstpunkt and Z 1 and Z 2 alternately with pressure applied. Semit this connecting rod unites the distributions of a high-speed one Eccentric press and a slow hydraulic press with linear force curve for Drawing work.
