Definitions

  • Metal extruders are usually designed as frame presses and consist of a cylinder spar, a counter-spar, these connecting to a frame tie rods (columns) and a in the frame of a running in the cylinder of the cylinder spar Piston moving strut.
  • direct pressing is a die and a pick for a for pressing the next block is supported on the counter-spar, while a block squeezing ram with the strut of the piston moves becomes.
  • indirect pressing is on the counter-spar one Stem supports supported while the transducer with a Closing disc receives a block to be pressed and is moved by the strut of the piston.
  • the invention is based on the object, the disadvantages of known drive arrangement of metal extrusion press, which are conditioned by the need to deal with big ones Flow rates with high flow velocity, as they are results when trained according to the preamble of claim 1 Metal extruders to which the invention relates by means of the auxiliary piston-cylinder units in the retreat or idle stroke to be driven at high speed.
  • the invention Drive arrangement according to the characterizing features of Claim 1 is formed. Because of the piston with it on both sides same as extending through the cylinder piston rods Diameter of the cylinder in two cylinder chambers same Cross-sectional area is divided over the cylinder spaces on both sides of the piston connecting short circuit line quick transition of the oil from one cylinder chamber to another possible with low flow resistance, with a appropriate dimensioning of the short-circuit line and in this arranged switchable shut-off valve without difficulty can be complied with. It should be here the Flow velocity in the short-circuit line 8 m / sec and in the check valve do not exceed 12 m / sec.
  • the metal extrusion press shown in FIG. 1 has one a cylinder spar 1, a counter-spar 2 and connecting them Tie rods 3 formed frame in which along the press axis bweglich a transducer 4 carrying transducer holder 5 and a punch a bearing 6 carrying strut 7 are guided.
  • With 8 is an illustrated in the direct pressing method in the counter-spar 2 supported die with die holder designated, at whose Place the indirect pressing a die stamp occurs.
  • the pickup holder 5 is moved by auxiliary piston-cylinder units 9, of which the transducer 4 during the pressing a strand through the die 8 is pressed against them and of which the pickup holder 5 with picker 4 for removal of the pressing residue deposited by the die 8 and optionally can be moved to load a block to be pressed.
  • the pressing of a block takes place during the direct pressing process by means of the press ram 6, the purpose of this with the spar 7 of a piston 10 via a piston rod 11 on the die 8 is moved to.
  • the piston 10 is connected to a second Piston rod 12 of the same diameter as the piston rod eleventh provided and guided in a cylinder 13, at both ends with cylinder covers or floors opposite the piston rods 11 and 12 is completed.
  • the frameless metal extruder shown in Figure 2 has a cylinder spar 21 and a counter-spar 22.
  • movably supported cylinder spar 21 are in the schematic diagram of two master cylinder 23 diametrically equidistant from the press axis or more than two Main cylinders in uniform distribution concentric to Pressing axis arranged.
  • the guided in the main cylinders 23 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-spar 22 are connected.
  • the master cylinders 23 are of Cylinder bottoms or covers against the piston rods 25 and 26 of the same diameter sealed so that both sides the piston 24 cylinder chambers 23a and 23b same effective area result.
  • the cylinder spar 21 is placed on the stationary counter-spar 22 too moved.
  • Press ram 27 is made from a receiver 28 by a die 29 pressed a block into a strand.
  • the die 29 supports itself from the counter-member 22 of the other for support of auxiliary piston-cylinder units 30, whose piston rods 30a are connected to the block receiver 28.
  • the auxiliary piston-cylinder units 30 serve to contact the block receiver 28 to the die 29 when pressing a block, to settle the block receiver 28 of the die 29 in the separation of Preßrestes and with appropriate design also for further Moving the block receiver 28th
  • the displacement of the cylinder spar 21 to the working stroke takes place according to the compression of a block relative to the strand slowly by acting on the piston 24 from the cylinder chambers 23 a via the pressure oil supply lines 31 while that from the Cylinder spaces 23b displaced oil via lines 32 discharged gets into an oil tank 33.
  • Auxiliary piston-cylinder units 34 provided the double-acting and be acted upon accordingly.
  • the slider 41 carries the ram 27 and is offset in the sliding direction provided for punch recording with a through hole 43, which introduced in alternation with the 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 5 and 6.
  • the counter-spar 22 is provided with a die changing device 44 provided, which is displaceable transversely to the press axis and with Receivers 45 is provided for exchanging matrices 29.
  • the receiver 28 is of the piston-cylinder units 30 firmly against the die 29th pressed. After completion of pressing the pickup 28 of the piston-cylinder units 30 so far from the die 29th removes that between the transducer 28 and die 29 a separation of the pressing residue is possible, as shown in FIG.
  • FIG 5 is further loading a for pressing pending block displayed simultaneously with the Separation of the pressing residue takes place.
  • the slider 41 spent in the position in which the through hole 43 is located in the press axis.
  • Lifting device is a bridge piece 46 between the pickup 28 and the through hole 43 is inserted in the slider 41.
  • From a block transport 47 is a block to be pressed in the space between the cylinder spar 21 and the support spar 37 to spent in the press axis.
  • Another way of loading one for pressing Pending block shows the figure 6.
  • the pickup 28 of the Piston-cylinder unit 30 slidable in front of the slider 41 after previously the ram 27 of the slider 41 so far has been moved laterally that he is outside the driving range the pickup 28 and the through hole 43 in the slider 41st lies in the press axis.
  • the of the block transport 47 in the space between cylinder spar 21 and support spar 37 in the Pressing axis introduced block is from the Thrust / piston rod 48 of the piston-cylinder unit 49 by the opening 50 in the cylinder spar 21 and the through hole 43 in the slide 41 is inserted into the bore of the pickup 28.
