Definitions
- the invention relates to a strand and tube press having a consisting of a cylinder spar and associated counter frame press frame, in which a movable block picker, which spends a loaded with a loader to be pressed block in pressing position in front of the counter-spar with die, are arranged, and on which a separating device, in particular a separating shears, for performing a separating cut perpendicular to the extrusion direction, is arranged at the mouth of the die, for cutting off a press residue. Furthermore, the invention relates to a method for separating a press residue during extrusion and tube pressing using such a strand and tube press.
- Such a strand and tube press or metal extrusion press of the type in question is known from EP 1 750 856 B1 and DE 102 31 328 A1 discloses a cutting shear with a special, two cutting surfaces knife has become known, the separator by means of a Cylinder is designed to pivot about a rotatable mounting, so that a smooth, clean separation cut can be achieved, possibly even in a protruding from the block receiver or recipient end of the block or metal bolt to be pressed.
- Such extrusion and tube presses require a separating device, in particular a shearing device, in order to separate the pressing residue remaining unavoidable during extrusion, which protrudes from the tool arranged on or in the counter-bar after the pressing process, and the extrusion or tube pressing of a following block or metal pin to continue unhindered.
- a separating device in particular a shearing device
- Particular emphasis is placed on a clean cut to separate the press residue to meet the quality requirements for extruding a plurality of blocks or metal studs.
- the shearing device must be moved over a distance of usually more than 800 mm from a rest position vertically perpendicular to the extrusion direction to cause the shearing of the press residue, and be returned over the same distance to its rest position.
- a pivoting of the shearing device or at least one shear blade or a shear plate disposed thereon prior to returning the shearing device in its rest position is reduced.
- a shearing device for severing a press residue remaining after the pressing operation, which is arranged vertically and horizontally displaceably on the press frame.
- the horizontal and vertical adjustability of the shearing device can be achieved that the separating device or shears in the rest position always only just above the tool, in particular the pressure plate, the die holder or the die, and not also above the block receiver (recipient) must be raised.
- the knife of the shearing device needs to be lowered only over a small distance, with the shearing device can be positioned by a preferably linear positioning drive so accurate that the press residue can be smoothly sheared.
- the space of the extrusion or tube press is limited to the necessary minimum and at the same time shortens the time required for the shearing time.
- the vertical displacement of the shearing device preferably perpendicular to the extrusion direction, a more accurate separation cut.
- the provision of rotary actuators for the shearing device or at least their shearing blades can preferably be dispensed with. It is preferred if the horizontal displacement of the shearing device is more than 100 mm, preferably between 150 or 250 mm, particularly preferably about 200 mm.
- a strand or tube press is provided which is able to drive away the shearing device from the tool horizontally and preferably to lift only in the vertical.
- the vertical stroke of the shearing device is less than 600 mm, preferably less than 500 mm, in particular preferably set between 450 and 500 mm.
- the shearing device should preferably be able to be removed from the travel of the tool upwards and then be moved by means of horizontal displacement in a rest position above the tool and preferably adjacent to the counter-spar.
- a shearing device is created whose path is optimally shortened from its rest position to a working position and at the same time does not restrict the pressing process itself. As a result, the non-productive times are limited to a necessary minimum.
- a hydraulic cylinder for effecting the vertical movement of the shearing device and / or an electric drive for effecting the horizontal movement are provided.
- Drives are able to perform specified displacements in a short time and with exact position.
- hydraulic cylinders in extrusion or pipe presses according to the invention can utilize the already provided hydraulic devices and are in the camp to apply the forces necessary for shearing the press rest.
- a method of separating a press residue during extrusion and tube pressing using a string or tube press according to the first aspect of the invention is claimed.
- the method according to the invention comprises at least the steps of pressing a workpiece from a billet receiver against the counter-spar, returning the billet after pressing to a home position, vertically displacing the presser-shearing shearing device, shearing the shearing device vertically after shearing and horizontal Moving the shearing device in a rest position.
- a horizontal displacement of the shearing device takes place away from the block receiver.
- This horizontal displacement is preferably carried out by at least 3 mm, more preferably by 5 to 10 mm.
- the shearing device and in particular a cutting blade or a shear plate of the shearing device is aligned parallel to the counter-spar at least during shearing. It is particularly preferred if the shearing device is aligned parallel to the counter-spar during the entire process.
- FIG. 1 shows a strand or pipe press according to the invention with a shearing device in rest position
- FIG. 2 shows the strand or tube press according to the invention from FIG. 1 with a horizontally displaced shearing device
- FIGS. 1 and 2 shows the strand or pipe press according to the invention from FIGS. 1 and 2 after the shearing off of a press residue
- Figure 4 shows the completion of the inventive method with the shearing device in its rest position.
- FIG. 1 shows a schematic view of a strand or tube press 1 according to the invention in a rest position, wherein a shearing device 4 carrying a shearing blade 4a is arranged above a tool 9 between a counter-member 3 and a block-holder 2.
- the billet 2 presses a block (not shown) through the tool 9 and the counter-spar 3 to produce the extruded product.
- the shearing device 4 In this working position the strand or tube press 1, the shearing device 4 remains displaced upward so that it remains completely above the tool 9, but only laterally offset to the counter-member 3 in its rest position.
- the vertical and horizontal displaceability of the shearing device 4 is effected in this embodiment by a hydraulic displacement cylinder 7 and an electric drive 6.
- Figure 2 shows a first step in carrying out the method according to the invention, in which the shearing device 4 is moved horizontally in the direction X to the right by the hydraulic cylinder 6 a position at which the shearing device 4, in particular the shearing blade 4a, aligned with the right edge of the tool 9 is arranged on the counter-member 3, wherein protruding from the right side of the tool 9 of the press rest 5.
- the block receiver 2 has been displaced to the right against the extrusion direction, in order to extrude a further block onto the counter-spar 3 and the die after separation of the pressing residue 5.
- FIG. 3 shows a further step of the method according to the invention, in which the shearing blade 4a of the shearing device 4 has been moved downward along the arrow Y under the action of the hydraulic cylinder 7, so that the cutting edge of the cutting blade 4a on the right side of the tool 9 is exactly parallel the tool 9 has been moved down, and so has sheared the press rest 5.
- Figure 4 finally shows how Figure 1 again the rest position of the extrusion or tube press 1 according to the invention, in which the shearing device 4 along the arrow Y vertically upwards and along the path X horizontally to the left in the rest position adjacent to the counter-3 has been moved.
- the cutting blade 4a is above the tool 9 and thus gives the path for the block picker 2 on the tool 9 and the counter-member 3 completely free.
- An appendix Lift the cutter 4 beyond the position shown or pivoting of the cutting blade 4a from the vertical shown out is therefore not required.
