- a press within the meaning of the present invention is, for example, a metal extrusion press as a horizontal or vertical extrusion press with a press frame and at least one moving crosshead or pickup holder that is slidably guided within the press frame, for example on guide columns.
- EP 3 003 701 B1 relates to a system and method for adjusting slides of a movable crossbeam of a press in relation to a column of the press on which the slide block can slide.
- the adjustment system includes a first wedge configured to be integral with the moveable crosspiece, a second wedge to which the slide block is fixed, a pin defining an axis and having a first end eccentric with respect is arranged on the axle, the first end being received in a cavity provided in the second wedge and a first actuating means for actuating the pin, which is arranged such that by rotating the pin the first end causes the second wedge to slide on the first Wedge effected along a cross-axis direction.
- the pin is moved between a locked and an unlocked position by means of a second actuating means, which is designed as a hydraulic cylinder.
- a second actuating means which is designed as a hydraulic cylinder.
- the pin In order to change the position of the movable wedge and hence the position of the sliding block, the pin must first be moved to the unlocked position. After that, the game will have a Rotation of the pin adjusted with its eccentric end. After the adjustment is complete, the pin is moved back to the locked position.
- the object of the invention is to provide an adjustment system of the type mentioned at the outset which is structurally simple and can be operated automatically.
- the object is achieved by an adjustment system having the features of claim 1.
- the object is also achieved by a method for adjusting the position of at least one sliding block of a slideway on a press with such an adjustment system having the features of claim 10.
- Advantageous configurations of the invention result from the dependent claims.
- an adjustment system for adjusting the guide play of a sliding guide for movable parts of a press, the adjustment system having at least one adjustable guide element which has at least one sliding block which can be adjusted transversely to the direction of movement of the part of the press to be guided, at least one adjusting wedge and comprises at least one guide wedge, the adjustment of which relative to one another causes a displacement of the sliding block transversely to the direction of movement of the movable part, the adjustment system according to the invention being characterized in that the adjusting wedge can be steplessly adjusted by means of at least one spindle drive.
- the adjustment system according to the invention can be an integral part of a press, but it can also be designed as a correspondingly prefabricated separate structural unit.
- Movable parts of a press are, for example, moving beams, pickup holders and the like, which can be moved, for example, between transverse beams or yokes of a press frame on guide columns or the like.
- the adjustment system according to the invention can preferably be installed in an open-die forging, die, isotherm forging, ring blank, piercing, drawing, deep-drawing and/or extrusion press.
- the adjustment system according to the invention can be realized in a particularly structurally very simple manner.
- the stepless adjustment by means of a spindle drive makes it possible to carry out automated adjustment of the guide play of the sliding guide in a relatively simple manner.
- the essence of the invention is that the adjustability via a pair of wedges comprising an adjusting wedge and a guide wedge cooperating with this is accomplished, the adjusting wedge being continuously displaceable via a spindle connected to it in the direction of the spindle axis and thus extending the guide wedge perpendicularly to the spindle axis. or let it drive in.
- the adjusting wedge and the guide wedge lie against one another, the adjusting wedge being movable parallel to the spindle axis by actuation of the spindle drive and thereby displacing the guide wedge transversely to the spindle axis.
- the spindle drive comprises at least one spindle driven by a servomotor, which interacts with a movement thread of the adjusting wedge.
- the adjusting wedge can be designed with a corresponding threaded hole.
- a servomotor in the sense of the invention can also have a gear and/or act on more than one spindle.
- At least one sensor is provided, which detects the guide play of the sliding guide and outputs this to a control and/or regulating device for automatic adjustment of the guide play.
- the spindle, the adjusting wedge and the guide wedge can be arranged in a common housing and form a structural unit with the sliding block as an adjustable guide element.
- the spindle is expediently rotatably mounted in a bushing of the housing. Furthermore, the slide block is expediently fastened to the guide wedge in an exchangeable manner.
- a press with an adjustment system of the type described above can include a press frame and at least one crosshead and/or receiver holder that can be moved within the press frame, as well as sliding guides for the crosshead and/or the receiver holder.
- the sliding guides can be provided, for example, on guide columns of the press frame, each cooperating with a sliding block of an adjustment system according to the invention.
- the press can be designed, for example, as a 2 or 4 column press.
- the method is characterized in that the guide play between the sliding block and a sliding surface of the part of the press to be moved is measured and compared with a specified guide play as a target value, with the spindle of the adjustment system being adjusted or turned as necessary until the Actual management game (actual game) with the specified or predetermined required management game (target game) matches.
- the setting system is calibrated and the measurement data recorded during this process is saved.
- forecasts about the further development of the press or maintenance intervals can be derived.
- the recorded measurement data are preferably recorded on a data memory and processed for later evaluation. In this way, for example, subsequent fluctuations in the quality of the product can be compared and/or explained with the measurement data from the press.
- the measurement data is visualized for the system operator and deviations from the target value are highlighted in color.
- the spindle can be adjusted automatically via an actuator depending on a measured value of the guide play detected by a sensor.
- a stepper motor for example, can be provided as the actuator.
- the adjustment of the spindle is detected by means of at least one setting value transmitter and a point in time for the necessary exchange of the sliding block is calculated from the completed adjustment path.
- the adjustment path that has already been completed can, for example, be summed up in a control and/or regulating device.
- Figure 1 is a sectional view of an adjustable guide member of the
- Figure 2 is a sectional view corresponding to Figure 1 of the adjustable
- the adjustment system comprises at least one guide element 1 of the type described below.
- the adjustment system can comprise a plurality of guide elements of the type described below and means for controlling and/or automatically actuating the guide element 1 or a plurality of guide elements.
- the guide element 1 shown in the figures comprises a housing 2 in which a spindle 3 which is rotatably mounted in a bushing 4 extends.
- the spindle 3 extends through first and second threaded bores 6, 7 of an adjusting wedge 5, which can be displaced within the housing 2 by rotating the spindle 3.
- the thread of the threaded bores 6 , 7 is a movement thread designed to complement the thread of the spindle 3 .
- the adjusting wedge 5 rests with a sliding bevel against a sliding bevel of a guide wedge 8 which is connected to a sliding block 9 or a sliding plate.
- the sliding block 9 is designed as a wearing part and, as can be seen from FIG arranged press.
- the distance S of the sliding block 9 to the guide roller 10 defines the guide play of the slide guide.
- the spindle 3 is provided at its end protruding from the housing 2 with an engagement 11 for a tool or for the drive axle of a motor, not shown.
- the spindle 3 is turned either by hand or with a motor.
- the rotary movement allows the adjusting wedge 5 to slide in or against the direction of the arrow A shown in Figure 2, with the guide wedge thereby sliding in or against the direction of the arrow B also shown in Figure 2 and the distance S between the guide column 10 and the sliding block 9 either increased or decreased.
