CENTERING DEVICE FOR FLAT WORKPIECES IN A PRESS AND METHOD FOR ADJUSTING SUCH A CENTERING DEVICE

摘要

The invention relates to a centering device (1) for flat workpieces, particularly for plates made of sheet metal to be processed in a press, comprising a first table (100.1) rotatable about a first vertical axis (90) for accommodating the workpiece and a second table (100.2) rotatable about a second vertical axis (90) for accommodating the workpiece. The second table (100.2) is located to the side of the first table (100.1) and a supporting plane of the first table (100.1) substantially coincides with a supporting plane of the second table (100.2). The device further comprises a rotating mechanism (45, 46, 50, 61) mechanically coupled to the first table (100.1) and the second table (100.2) such that the first and the second table (100.1, 100.2) can rotate together about a third vertical axis (50). If both tables (100.1, 100.2) are rotated together about the third vertical axis (50), then the tables (100.1, 100.2) form a common supporting surface. In the other operating mode, the tables are rotated separately about the mutually spaced vertical axes (90); the tables and their supporting surfaces thus move relative to one another. Using the device according to the invention, both a single workpiece that can take up the entire width of the centering device (1), and two workpieces of lesser width simultaneously, can be correctly oriented for subsequent processing.
