Bar guide unit and bar supply system for bar supply system

摘要

The invention relates to the bar guiding unit of a bar feeding system, which is used for feeding longitudinal bars (10) into machining equipment. The bar guiding unit is composed of at least one first guiding member (6) and at least one second guiding member (7). The first guiding member (6) and the second guiding member (7) are arranged in a support while moving relative to each other. The bar guiding unit further comprises a drive unit used for driving the first guiding member (6) and the second guiding member (7) to move relative to each other between a closed position and an opened position. At the closed position, the bars (10) are held. At the opened position, the bars (10) are released. The first guiding member (6) and/or the second guiding member (7) are movably supported by damping chambers (20, 21), wherein one guiding member is supported by one damping chamber. At the closed position, one or more damping chambers (20, 21) are filled with the damping fluid so as to absorb the movement of the one or more guiding members (6, 7).
