Definitions

• the invention relates to a device for coupling a displacement means a roll changing carriage / carriage or a roll stand or one Roll stand.
• Removal trolley or the rolling stand with a vertical locking cylinder equip. This is used to lock the piston rod of the displacement cylinder, which is why a wedge is actuated by the vertical cylinder.
• Shift cylinder required locking cylinder requires that to Roll stand a separate pressure medium supply with quick fasteners or a Media chain is laid. Furthermore, a mobile or stationary steering position is available Control of the locking cylinder required.
• the invention has for its object to a generic device create with which the coupling and uncoupling of the moving means to the object to be removed can be reached more easily, especially in Universal rolling mills, the rolling stands that can be moved in two rolling positions exhibit.
• the displacement means with a coupling head is formed, which has an axial in and inside Disengaging element, to which radially displaceable locking bodies are assigned, which in engage a clutch housing enclosing the clutch head in situ.
• the axial input and Release element and the associated radially displaceable locking body simple and advantageous way the coupling head of the displacement means with the Coupling or uncoupling the clutch housing without an additional Locking cylinder or a locking means is necessary.
• a preferred embodiment of the invention provides that the displacement means Actuating cylinder is, the piston rod is provided with the coupling head, which as axial adjustment element formed on its outer circumference with helical slopes Plunger picks up. About the piston rod of the actuating cylinder Push the coupling head into the coupling housing or pull it out.
• the displacement means it is also possible for the displacement means to have a spindle Motor drive or the like on which the coupling head is arranged. That as Plunger-trained axial adjustment element causes over its lifting slopes at the same time that the radially displaceable locking body with the clutch housing in Engaged or released from engagement.
• the latching bodies are advantageous in through openings the coupling head holds balls that can be engaged and disengaged, which is assigned a circumferential locking groove in the clutch housing.
• the balls are similar to a ball cage, movable but fail-safe, in the Passages of the coupling head held. So engages with a radial Displacement of the balls only one ball section in the complementary locking groove of the clutch housing.
• Another embodiment of the invention provides that the cylinder housing one the piston surface of the cylinder piston and one assigned to the plunger Has pressure medium connection, one in the piston rod to the plunger leading pressure medium line is arranged, the radial holes on the piston-side cylinder space is connected. Via the pressure medium connection of the Cylinder piston is pressurized with a pressure medium, so that the Piston rod of the cylinder with its coupling head forward in that The clutch housing engages. If after that the one assigned to the plunger Pressure medium connection is acted upon by a pressure medium, flows or flows this through the pressure medium line in the piston rod to the plunger, which is thereby axially displaced and the balls of the Presses the coupling head into the circumferential locking groove of the coupling housing.
• the compression spring of the plunger is convenient in arranged a center hole of the plunger and supports with its free front end at the bottom of a bore of the plunger Coupling head.
• a preferred application of the invention provides that the clutch housing a rolling stand is flanged. This brings e.g. the advantage of a universal scaffold with itself that this after coupling to the displacement means in a simple manner a second rolling position (shift about 700 mm) can be adjusted. Is too it is possible - assuming a corresponding stroke of the displacement means -, For example, a changing stand or a roller changing car, which then with the Coupling half must be completely out of the rolling mill except for one Exchange platform to move.
• the clutch unit with its axial engagement and disengagement element as well as the radially displaceable locking bodies in the coupling head anyway required shifting means is integrated, the known Sliding devices additionally required locking cylinders are omitted; it therefore, the otherwise incurred costs for a cylinder, the installation save additional pressure lines and a separate control station.
• a displacement means 1 designed as an actuating cylinder 2.
• Actuating cylinder 2 has a piston rod 3, which is connected to a coupling head 4 Is provided.
• a coupling head 4 Is provided in the interior of the coupling head 4
• the plunger 5 has its outer circumference lifting slopes 6.
• Coupling head 4 locking balls designed as balls 8 limited and held disengageable.
• the coupling head 4 engages in a coupling housing 9, the in the exemplary embodiment to a roll stand 10 shown only schematically here is flanged.
• the jacket 11 of the clutch housing 9 is one of the balls 8 complementary, circumferential locking groove 12 formed.
• the cylinder housing 13 of the Actuating cylinder 2 is a pressure medium connection 14 for the piston surface 15 of the Cylinder piston 16 and a pressure medium connection 17 assigned to the plunger 5.
• a pressure medium connection 14 for the piston surface 15 of the Cylinder piston 16 and a pressure medium connection 17 assigned to the plunger 5.
• Port 17 is connected to the plunger 5 via an arranged in the piston rod 3
• Pressure medium supply line 18 in connection, which via radial bores 19 to the piston-side cylinder space 20 is connected.
• the pressurized piston rod 3 of the actuating cylinder 2 is with her Coupling head 4 immersed in the coupling housing 9 until it stops.
• Both Pressure medium connections 14, 17 are under pressure, the connection 14 flowing and acting on the piston surface 15 pressure medium the piston rod 3rd has moved forward while the pressure medium connection 17 in the pressure medium supplied to the cylinder chamber via the radial bores 19 into the Propellant line 18 propagated and the plunger 5 against a compression spring 21st has moved forward; in this operating position the coupling is finished.
• the Compression spring 21 is located in a central bore 22 of the plunger 5 and is supported with its free front end 23 at the bottom 24 of the plunger 5 receiving Bore 25 of the coupling head 4.
• the operating position with the coupling head 4 fixed in the coupling housing 9 is shown in the lower part of FIG. 1.
• the plunger 5 has 6 over its slopes the balls 8 pressed outwards into the circumferential locking groove 12 (see lower half of Fig. 2).
• the pressure medium connection 14 is depressurized. It is now only the annular surface 27 of the cylinder piston 16 via the pressure medium connection 17th under pressure so that the piston rod 3 in the actuating cylinder 2 to the rear moved and moves the coupled roll stand 10.
• the pressure medium connection 17 is depressurized made.
• the compression spring 21 can relax and the plunger 5 with the Press the bevel 6 towards the piston rod 3.
• the balls 8 get by with it their free seat and can freely in the passage openings 7 in their Fall out of latch position.
