Definitions
- the invention relates to an extrusion and tube press, comprising a press frame consisting of a cylinder spar and counter spar, which is connected to one another by means of upper and lower prestressed tension slats and upper and lower pressure supports, in which a movable running spar and a movable pick-up, which is inserted with a loading device, is to be pressed Blocks in the press position in front of the counter beam with die, are arranged.
- Such a horizontal extrusion press or horizontal metal extrusion press has become known from EP 0 428 989 A2.
- a block heated in a furnace to the pressing temperature is taken over by the loading trays and brought into the press axis into the free space between the die and the press plate by swiveling swivel arms arranged on a shaft in a manner fixed against relative rotation - so-called swivel loaders as an alternative to likewise conventional linear block loaders.
- the barrel spar and the block receiver are moved towards the die by means of an adjustment cylinder, the block receiver being slipped over the block.
- the axially movable pivot arm is shifted on the shaft until the block is clamped between the press ram and the counter beam or the die fastened in a holder.
- the transducer is moved using side cylinders.
- extrusion and tube presses mentioned at the outset are well known and work according to various pressing processes, e.g. in pipe pressing over a fixed mandrel, as is preferably used for aluminum and in particular for the production of small pipes.
- direct and indirect tube pressing the block can be punched in the press (see e.g. "ALUMINUM 49 (1973) 4, pages 296 to 299").
- the spar and transducer have remained unchanged either on a separate base frame or on the connecting elements between the spars (pressure box, lamella or Pressure sleeve, tie rod) over slide plates and slide bushes.
- the latter mostly consist of bronze materials or sliding plastics, so that these components are subject to relatively heavy wear.
- the inevitable consequence of this is that the press alignment has to be checked and adjusted at regular short intervals and the slide or guide units have to be replaced. Since this wear has a direct impact on the service life of the tools, the product quality, the maintenance intensity and ease of use as well as the overall press condition, e.g. also on the wear of the secondary cylinders, pressure plates, etc., the guide systems are of crucial importance for general press operation.
- the compact structural unit of the press frame which forms the frame of the extrusion press and which functionally absorbs the pressing force.
- the maximum force to be transmitted by the frame is made up of the forces generated by the plunger of the press cylinder, the side cylinders and the transducer displacement cylinders. Due to the four cylinder bars and counter beam, which are non-positively connected to one another via four prestressed tension slats and four pressure supports, the expansion path is reduced by more than 50% compared to non-prestressed columns with the generally customary dimensions. However, there is still an elastic behavior of the press frame, which has an impact on the running accuracy of the transducer and the running bar and thus the sliding guides.
- the invention is therefore based on the object of creating a generic extrusion and tube press without the disadvantages mentioned, in particular to improve the operating properties even under high loads.
- this object is achieved in that the running bar and the pick-up can be moved in the press frame with guide units having rolling elements.
- the guide system does not contain sliding or wearing parts, but rather rolling elements (rollers, barrels, balls, needles etc.) that are not subject to sliding wear, several advantages can be achieved at the same time.
- a one-time hot alignment of the extrusion press is sufficient to ensure that the press axis is set once.
- process-related influencing factors e.g. Eccentric action of the pressing force due to uneven temperature distribution of the material to be formed or asymmetrical upsetting of the block, the rollover frequency, the impact load and the cleanliness of the environment, but also also design-related as well as manufacturing or assembly-related influencing variables, for example the position of the components in the press frame during assembly of the guides and the straightness of the mounting surface on the pressure supports.
- process-related influencing factors e.g. Eccentric action of the pressing force due to uneven temperature distribution of the material to be formed or asymmetrical upsetting of the block, the rollover frequency, the impact load and the cleanliness of the environment.
- design-related as well as manufacturing or assembly-related influencing variables for example the position of the components in the press frame during assembly of the guides and the straightness of the mounting surface on the pressure supports.
- An embodiment of the invention provides that the rolling elements of the guide units are connected to the lower pressure supports Guide rails run, with the running spar advantageously being arranged on two guide units and the pick-up on four guide units, of which either one or two are supported on each of the parallel parallel spaced guide rails.
- the exact number of guiding units is nevertheless always to be interpreted in the specific individual case, for example depending on the size of the extrusion press.
- An X or O arrangement can be provided in the guides for the rolling elements. Compared to X-shaped rolling elements, rolling elements in an O arrangement are characterized by higher rigidity, but are more susceptible to manufacturing errors and assembly tolerances.
- the running bar and the receiver rest on the guide units via free supports.
- a decoupled system in which the crossbar and the transducer are firmly connected to their guide units by specifying which of the three axes (one or all three) is fixed, a decoupled system can be achieved.
- the crossbar and the transducer can move in all three axes (X-Y and Z-axis) independently of the guide unit.
- the free supports have a pressure plate, a spherical cap and a sliding plate, starting from the guide units toward the running bar or sensor.
- the spherical cap provided in a complementary receptacle, prevents one of e.g. due to manufacturing tolerances or assembly errors, while the pressure plate ensures an even distribution of tension on the guide units and the sliding plate helps to tolerate axial movements of the pressure supports.
- the spacer can be, for example, one or more interposed shims or set screws.
- the free supports of the guide units are acted upon by a spring force, preferably with a preload. Due to the spring force, for example a spring assembly, in particular a pretensioned spring assembly, the pickup or the spar are returned to the center of the press in the event of deflections.
- Figure 1 is a perspective view of a detail of an extrusion and tube press whose press frame - shown without counter beam - with the running beam and pick-up arranged therein.
- Fig. 2 seen the press frame of Figure 1 in partial cross-section with a view of the transducer holder from the left in Fig. 1.
- FIG. 3 shows as a detail a roller bearing of a guide unit on a guide rail of the press frame according to FIG. 1;
- Fig. 5 is a schematic representation of the individual routes of the modules spar and transducer.
- a well-known horizontal extrusion press is shown as a single component, the compact press frame 1 forming the press frame.
- this consists of a cylinder spar 2 which is braced via four tie bars 3 with a counter bar not shown here, which is provided on the free ends of the tie bars 3 on the left in FIG. 1.
- pressure supports 4 which enclose the tension plates 3 between the cylinder spar 2 and the counter spar, also contribute.
- the pressure supports 4 also serve to receive a guide rail 5 movable in the press frame 1 and a movable transducer 6.
- the spar 5 is by means of displacement cylinder 10 and Move transducer 6 through displacement cylinder 11. It is also clear from the diagram that the running distances 7 and 8 increase with increasing press size. Both the running beam 5 and the pickup 6 run with rolling elements 12 or 13a and 13b (see FIGS. 3 and 4) on guide rails 14 which are each connected to the two lower pressure supports 4 of the press frame 1 (see. 1).
- the rolling elements 12 or 13a or 13b are mounted in guide units 15 designed as carriages in either an O arrangement (cf. the rolling elements 13a in FIG. 4) or in an X arrangement (cf. the rolling elements 13b in the right partial figure 4).
- the running beam 5 is arranged on each side via a guide unit 15 and the pickup 6 via two guide units 15 on each side on the guide rails 14; the two guide units 15 of the transducer 6 are connected to one another via a bridge 16.
- the spar 5 and the transducer 6 are - as shown in FIG. 2 using the example of the spar 5 - on free supports 17 on the guide units 15, ie they are not firmly connected to the guide system.
- the free supports 17 are formed by a spherical cap 18 which is arranged in a complementary receptacle 20 which engages in the running beam 5 (or transducer 6) with the interposition of a sliding plate 19.
- a pressure plate 21 is also arranged between the guide units 15 and the spherical caps 18, and fitting plates can still be fitted above the sliding plate 19 22 are provided, by means of which the height adjustment of the spar 5 or sensor 6 can be adjusted to the center of the press.
