Definitions
- Metal extrusion presses are mostly designed as frame presses and consist of a cylinder beam, a counter beam, these into a frame connecting tie rods (columns) and an in the frame of one running in the cylinder of the cylinder spar Piston movable barrel.
- a matrix and a sensor for one for pressing coming block supported on the counter beam, while the block Squeezing ram with the barrel moved by the piston becomes.
- the indirect pressing process is on the counter beam Die stamp supported while the transducer with a Sealing disc receives a block to be pressed and is moved with the barrel by the piston.
- auxiliary piston-cylinder units required by the idle stroke and return stroke are in the previously known metal extrusion press frameless design between the counter beam and the cylinder beam arranged, which is a structural disadvantage, since the Working space is narrowed as a result.
- US-A-4 155 300 intended arrangement of the auxiliary drive between the spar and the press frame is not in the frameless design possible.
- the object of the invention is to remedy this disadvantage.
- the support bar can furthermore a piston-cylinder unit bear in the press axis is arranged and the piston rod as a fin bumper for between the support beam and the master cylinder beam in the press axis insertable and through a central opening in the master cylinder spar press blocks to be brought into the transducer is formed.
- the frameless metal extruder shown in Figure 1 has a cylinder beam 21 and a counter beam 22.
- two master cylinders 23 diametrically in the schematic diagram at the same distance from the press axis or at more than two Master cylinders in an even distribution concentric to the Press axis arranged.
- Pistons 24 are provided on both sides with piston rods 25 and 26, of which the piston rods 25 are arranged with the stationary Counter beam 22 are connected.
- the master cylinders 23 are from Cylinder bottoms or covers opposite the piston rods 25 and Sealed 26 of the same diameter, so that there is on both sides the piston 24 cylinder spaces 23a and 23b the same effective area surrender.
- the cylinder beam 21 is placed on the stationary counter beam 22 too moved.
- Press ram 27 is made from a transducer 28 through a die 29 a block pressed into a strand.
- the die 29 supports down on the counter beam 22 for further support of auxiliary piston-cylinder units 30 serves the piston rods 30a are connected to the block sensor 28.
- the auxiliary piston-cylinder units 30 serve to press the block sensor 28 to the die 29 when pressing a block, for setting down of the block pickup 28 from the die 29 when the Press remnants and, if appropriately dimensioned, also for further Moving the block receiver 28.
- the displacement of the cylinder spar 21 to the working stroke takes place corresponding to the pressing of a block relative to the strand slowly by acting on the pistons 24 from the cylinder spaces 23a via the pressure oil supply lines 31 while that from the Cylinder spaces 23b displaced oil discharged via lines 32 is in an oil tank 33.
- Auxiliary piston-cylinder units 34 provided the double acting and can be acted upon accordingly.
- the cylinder spar 21 is transverse with one in guides 40 to the press axis displaceable slide 41 provided by a piston-cylinder unit 42 is actuated.
- the slider 41 carries the press ram 27 and is offset in the sliding direction provided with a through hole 43 for stamp receiving, which alternately introduced with the press ram 27 in the press axis can be, so that through this through hole 43 a press block can be loaded, as shown in Figures 4 and 5.
- the counter beam 22 is provided with a die changing device 44 provided, which is displaceable transversely to the press axis and with Recordings 45 is provided for replaceable dies 29.
- FIG 4 is also the loading one for pressing shown pending block, which simultaneously with the Removal of the press residue takes place.
- the slide 41 placed in the position in which the through hole 43 is located in the press axis.
- Lifting device is a bridge piece 46 between the transducers 28 and the through hole 43 introduced in the slide 41.
- a block to be pressed is in a block transport 47 the space between the cylinder spar 21 and the support spar 37 to placed in the press axis.
- One as a bumper trained piston rod 48 of a piston-cylinder unit 49 which is attached to the support beam 37 in the press axis the press block to be loaded through an opening 50 in the cylinder spar 21 and through the through hole 43 in the slide 41 via the Bridge piece 46 in the bore of the transducer 28.
- lowering the bridge piece 46 and moving the ram 27 back into the Press axis can start the next pressing process (in figure 2a shown starting position). The movements are controlled so that they overlap as much as possible.
- FIG. 5 Another way of loading one for crimping Figure 5 shows the next block, saving one the liftable and lowerable bridge piece is the transducer 28 of the Piston-cylinder unit 30 displaceable up to the slide 41 after the ram 27 from the slide 41 so far has been moved laterally so that it is outside the driving range of the transducer 28 and the through hole 43 in the slide 41st lies in the press axis.
- the block transport 47 in the space between cylinder spar 21 and support spar 37 in the Press axis introduced by the block Push-in / piston rod 48 of the piston-cylinder unit 49 through the opening 50 in the cylinder spar 21 and the through hole 43 pushed into the bore of the transducer 28 in the slide 41.
- the cylinder spar 21 is then retracted so that the shutter 52 releases from the pickup 28 so that the Slider 54 can be moved so far that the Through hole 53 is located in the press axis.
- the Following cylinder spar 21 is the pickup 28 in the Starting position (see Fig. 8) retracted.
- One of those Block transport 47 in the space between the cylinder spar 21 and the support beam 37 and the press block brought into the press axis is from the push-in / piston rod 48 of the piston-cylinder unit 49 through the opening 50 in the cylinder cross member 21 and the Return bore 53 in the slide 51 in the bore of the transducer 28 pushed so that the press for a subsequent pressing operation is ready.
