ABSTRACT:
The guide columns of the punch press are releasably mounted to the base plate. Guide sleeves project from the ram and the guide columns are guided inside of the these guide sleeves. The sealing between the guide columns and the guide sleeves is made by piston rings. Leakage oil is collected at the oil collecting ring and discharged through a transfer channel (11) located in the ram (2) towards an inner space of the guide sleeve. A horizontally mounted check valve is located in this oil transfer channel. The guide column includes a leakage oil channel which extends to the oil collecting space in the base plate. In operation oil present in the oil collecting ring is pumped into the oil collecting space due to the continously changing of the volume of the inner chamber such that no leakage oil can enter the punching work space. The check valve opens during the upwards movement of the ram and closes during the downwards movement thereof. Those sections of the guide columns which incorporate a sealing and guide function are surrounded by the respective guide sleeve at all operational positions of the ram and are accordingly protected against injury. By means of the above design a penetrating of lubricating oil into the punching works space is impossible and no large loss of lubricating oil is possible.
