Adjusting system for adjusting the guide play of a sliding guide for movable parts of a press, and method for adjusting the position of at least one sliding block of a sliding guide on a press

An adjusting system for adjusting a guide play of a sliding guide for a movable part of a press, comprising:

• an adjustable guide element (1), which comprises
• a sliding block (9), the sliding block (9) being movable transversely to a direction of movement of the movable part;
• an adjusting wedge (5);
• a guide wedge (8), the guide wedge (8) cooperating with the adjusting wedge (5);
• a spindle drive with a spindle (3);
• a measured value encoder configured to record the guide play of the sliding guide;
• and
• an open-loop or closed-loop control device;
• wherein movement of the adjusting wedge (5) relative to the guide wedge (8) causes the sliding block (9) to shift perpendicularly to the direction of movement of the movable part,
• wherein the adjusting wedge (5) is continuously adjustable by the spindle drive,
• wherein the spindle (3) cooperates with a movement thread of the adjusting wedge (5), and
• wherein the measure value encoder records the guide play of the sliding guide and outputs this to the open-loop or closed-loop control device for automatic readjustment of the guide play.
