Definitions
- the invention relates to a method for extrusion and an extrusion system, in particular for the production of curved extrusion products, the molded product being formed in a die upstream of a counter beam of the extrusion system and then being bent or bent by the action of external forces.
- the pressure medium can be a pressure roller, a sliding surface that generates a transverse force, or a roller cage.
- the distance determined for the reaction must be maintained so that the extruded product is influenced at the same time as or immediately after the shaping extrusion process when bending or bending in such a way that the workpiece cross sections formed in the extrusion die are not parallel to one another emerge from the die, but stand at an angle to each other.
- the invention has for its object to provide a method and an extrusion press of the type mentioned, which allow simple means to produce pressed products with a wide range of bending radii.
- pressing phases with gradual pressing of the strand and those with bending action on the strand can alternate in time.
- the strand After pressing a straight strand section, the strand needs only to be deflected with a more or less large external force so that there is a first bending radius, the strand then being able to be squeezed out again over a desired section before a further bending radius is trained.
- the chronological sequence of the straight extrusion process and the action of force to bend or bend the strand can be controlled here by means of the superordinate computer of the extrusion system.
- An extrusion system for achieving the object on which the invention is based has a counter spar which is designed with a lateral spar opening which extends transversely to the straight extrusion direction. It only needs to open to one side of the spar and creates the space required to deflect the strand in the counter spar and to provide it with the desired bending radius.
- the side opening has an integrated actuator.
- This can be, for example, a pressure-loaded cylinder or the like with a pressure head on its end of the piston rod that dips into the spar opening from the opposite side.
- the counter beam is made several times higher and advantageously in a two-column construction in relation to the beam width, a very wide range of different and in particular very small bending radii can be produced. Because due to the above-average height, i.e. long and narrow counter beam, after a first turn, a next curvature can be created as soon as the section of the strand has covered the short distance to exit from the side opening ,
- a counter-holder is assigned to the actuator.
- a roller or another counter-holding element facing the strand with a curve is expediently suitable as a counter-holder, which is arranged below the line of fit of the strand.
- This counter-holder add-on element also helps to influence the bending radius to be produced on the strand by means of a more or less large diameter or radius of the curve adjacent to the strand.
- Figures 1 to 5 as a detail of an extrusion system in cross section of its counter beam and different operating phases for the production of curvatures or bending radii on an extrusion product.
- FIG. 7a, 7b in side view (Fig. 7a) and in front view (Fig. 7b) a modification of the counter beam according to Fig. 6a, 6b.
- Fig. 7a, 7b in front view (Fig. 7b) a modification of the counter beam according to Fig. 6a, 6b.
- the counter beam 2 or 102 and 202 are formed with a lateral opening 3 or 103 and 203, each of which extends transversely to the straight pressing direction 4 to a side of the spar.
- the side bar opening 3 is associated with an actuator 6 which extends with a piston rod 5 through the counter bar 2 into the side bar opening 3.
- This is set with a pressure head 7 on the strand 8, which runs in via a tool carrier 9 resting on the inlet side on the counter beam 2 with a pressure plate.
- a counterholder 10 in the form of a roller arranged in the counter beam 2 below the pass or pass line of the strand 8 counteracts the actuator 6 when it is set against the strand 8 with its piston rod 5 and the pressing head 7.
- the strand 8 is initially normal according to FIGS. 1 and 2, i.e. just squeezed until a leading strand section 8a (see FIG. 2) has passed through in the squeezing direction 4 with a desired length. If the actuator 6 is then pressed against the strand 8 at this point in time, the strand is provided with a curvature or a bending radius 11 (cf. FIG. 3).
- the strand 8 or 8a lies here on a table 12 of the outlet of the extrusion system 1.
- a straight strand section 8b is pressed after pressing 5, a further bending radius 11 shown in FIG. 5 is formed, so that extruded products with more than one curvature can also be produced on the same strand 8 in this way.
- the counter pillars 102 and 202 according to FIGS. 6a, 6b and 7a, 7b are distinguished by a very long and narrow construction with an above-average bar height.
- the counter beams 102 and 202 are designed in the embodiment in a construction with two columns 13a and 13b.
- the side rail opening 103 or 203 is only due to the narrow design up to the side opening end very short (cf. FIGS. 6b and 7b), so that successive bending radii can be formed on the same extruded product in a shorter sequence.
- the counter bars 102 and 202 are reinforced on their side facing away from the side bar opening 103 and 203 by a material bulge 14.
- the adjusting means bending the strand are not shown for the counter spars 102 and 202 in the figures. While the pressure plate of the tool carrier 9 (see FIG. 1) is immersed in a spar recess 15 in the counter beam 102, the pressure plate 16, shown in dash-dot lines, rests on the counter beam 202 in the embodiment according to FIGS. 7a, 7b.
- the depth of the lateral spar opening 203 in the pressing-out direction 4 can be designed to be correspondingly larger compared to the variant according to FIG. 6a with otherwise the same spar dimensions.
