Definitions

  • the invention relates to methods and devices for compression molding profiles, bars, moldings or the like from small vegetable parts mixed with binders, in particular small wooden parts, which are cured in the pressed state by the action of heat.
  • a compression molding process of this type is specified in DE-A-30 35 701.
  • the profile or the like is then pressed in a press mold to achieve its final cross-sectional shape and cured by the action of heat.
  • the pressing process must be carried out as long as the binding agent does not yet produce a binding effect among the individual particles of the small parts used.
  • the only problem with the above-described method is to wait until the finished pressed molding or profile has hardened before a new pressing process can be initiated. In some cases it is also necessary to cool the mold before the next pressing can be carried out.
  • the invention is therefore based on the object of specifying further developed methods and devices with which it is possible to increase the productivity in the production of profiles, bars, moldings or the like quite considerably without having to increase the investment costs.
  • the solution to this problem according to the invention is based on DE-A-30 35 701 and consists in that the profile pressed into its final shape, with its pressing jaws enveloping the profile or the like, is pushed into at least one movable clamping device along its longitudinal axis while maintaining the final press position , whereupon the clamped profiles are cured under the influence of heat, while pressing jaws of another pressing jaw approach are returned to the pressing position of the press.
  • the invention is based on the idea of curing the finished pressed profiles or the like outside the press. This measure may not come as a surprise, because it seems logical in itself not to extend the pressing time of a press by the curing time.
  • a suitable device for carrying out the method according to the invention can be found in claim 4, the preamble of which is derived from US Pat. No. 3,762,852, according to which it is known to act on a molding compound from several directions by means of press jaws.
  • the press jaws remain in their effective range, while the pressed molded body is fed in a special form for curing.
  • such a system requires a large number of curing forms and is therefore very expensive.
  • a press space 1 is provided within a press, into which a blank profile 2 is inserted in the manner described below.
  • This profile blank 2 consists of small plant parts, in particular small wooden parts, which are mixed with binders. This mixture sets after the final compression by heat.
  • the invention also encompasses other profiles that change in cross-section, such as Support bars for pallets, supports, rods, rails, chair legs and the like.
  • press jaws 3, 4, 5, 6, of which the press jaws 3, 4 the web area of the finished profile 15 and the press jaws 5, 6 form the flange area. All of the pressing jaws 3 to 6 encompass the blank 2 or the finished profile 15 formed later.
  • a pre-compression measure is provided in the exemplary embodiment.
  • the pressing jaws 3 to 6 are located within the guides 7 assigned to them in the retracted position shown in FIG. 1.
  • FIG. 8 schematically shows a metering device through which the mixture to be pressed and mixed with binders is fed to a pre-pressing chamber, which is not shown in FIG. 1 for the sake of shortening the disclosure.
  • This pre-pressing space is actually formed by the shaft 20, which in the example of FIG. 1 is located above the pressing space 1.
  • This shaft 20 is delimited by the pressure bar 12 and the counter pressure bar 13, the distance of which can be varied by stroke generators 11, which are combined in a frame 10 together with the pressure bar 12 and the counter pressure bar 13.
  • this then presupposes the arrangement of a slide, not shown, between the metering device 8 and the pre-pressing tool 9.
  • the pre-pressing tool 9 can also be moved to the right in the drawing in FIG. 1 and during this movement the pressing bar 12 can be brought closer to the counter-pressing bar 13, the aforementioned pre-pressing being ended as soon as the pressing bars 12, 13 have reached the position shown in Figure 1.
  • the movement of the pre-pressing tool 9 is served by a stroke generator 14, which acts on the frame 10. In this case, the arrangement of a locking slide between the metering device 8 and the pre-pressing tool 9 is unnecessary.
  • the shaft 20 is reduced by approximately 2/3 of its width from the position below the metering device 8 to the position shown in FIG. This results in a corresponding pre-pressing of the mixture filled in the shaft 20, although the degree of pre-pressing can be chosen as required.
  • the pre-pressed profile blank in the position shown in FIG. 1 is initially above the press space 1. If the distance between the pressure bar 12 and the counter pressure bar 13 is increased more or less, the profile blank 2 can enter the press space 1 arrive. This is done either by gravity or by a stroke of the Above the profile blank 2 press jaw 6 in the rest position, which is moved downwards. At the end of this process, the profile blank 2 is in the position shown in FIG. 1 within the pressing space 1.
  • the lateral pressing jaws 3, 4 are then driven into the blank 2, which results in a pre-deformation with respect to the finished profile 15.
  • These lateral pressing jaws 3, 4 then remain in their pressing position, whereupon the vertical pressing jaws 5, 6 act again on the profile blank 2 until it has reached the shape shown in FIG. In this position, it is possible that the press jaws 3, 4 can be re-shaped again.
  • This multi-stage pressing process can be varied in different ways.
  • This pressing process can take place in the context of a so-called cold press.
  • the finished profile 15 shown in FIG. 2 is now to be moved out of the press chamber 1 along its longitudinal axis, it being important in the sense of the invention that the press jaws 3 to 6 should follow this movement.
  • the press jaws 3 to 6 are supported on roller tables 17, which in turn abut press punches 16.
  • the press punches 16 are moved by stroke generators 18. This results in a parting plane between the press jaws 3 to 6 on the one hand and the press dies 16 assigned to them, which extends parallel to the longitudinal axis of the profile 15.
  • the pressing jaws 3 to 6 are able to be moved out of the pressing space 1 with the finished pressed profile 15 in the direction of its longitudinal axis.
  • FIG. 1 shows webs 19 engaging behind in various forms.
  • these engaging webs 19 are shown in the form of dovetail guides and in the case of the press jaws 5, 6 in the form of hammer-head-shaped groove guides. This is intended to ensure that the individual press punch 16 should be able to convey the press jaw 3 to 6 assigned to it back from the press end position into the position shown in FIG. 1. It is obvious that such engaging webs 19 can be designed in different ways.
  • FIG. 3 it is shown how the profile 15, which is finished in its cross-sectional shape in the pressing chamber 1, is displaced along the longitudinal axis from the pressing chamber 1 and brought into a curing arrangement.
  • This curing arrangement has the purpose of receiving the finished profile 15 in a tensioned position and curing it, during which time a next profile blank 2 is deformed into the finished profile 15 in the press. For this purpose, it must be taken into account that the cycle of pressing the profile 15 takes significantly less than the curing time of this profile.
  • the curing device is designed in such a way that it can accommodate a large number of pre-pressed profiles 15.
  • FIG. 3 shows, the finished pressed profile 15 with its pressing jaws 3 to 6 is moved along its longitudinal axis by a stroke generator 21 in the context of the final press position, a pressing disk 22 of the stroke generator 21 not only the finished profile 15 but also the associated pressing jaws 3 to 6 deports.
  • This pushed unit 3 to 6, 15 is now transferred from the roller table 17 to the roller table 24, which is arranged in a tensioning device 23. Both roller tables 17, 24 are aligned with each other.
  • the term “clamping device 23” generally refers to an arrangement which is able to receive the pressing jaws 3 to 6 with the finished profile 15 clamped between them in a clamped position and to supply them for curing.
  • the tensioning devices 23 are located in a chassis 50 shown in FIG. 8, which can be moved along rails 25 which extend transversely to the direction of movement of the stroke generators 21. As will be shown later, this measure can be varied in different ways.
  • the slide 26 is used, which closes the press chamber 1 at one end on one side.
  • this slide 26 should allow the movement of the finished profile 15 along its longitudinal axis.
  • the slide 26 has a recess.
  • the press chamber 1 is either closed at the end or released at the end.
  • This slide also has a cutout 30 through which a stroke generator 31 can grip. With the help of its push-off disk 32, this stroke generator 31 serves to return a fully hardened profile 15 with its pressing jaws 3 to 6 back into the pressing chamber 1, but this is only one of several possibilities.
  • the clamping device 23 If the clamping device 23 has now received the finished pressed profile 15 with its pressing jaws 3 to 6 in the final pressing position, in the embodiment of FIG. 3 it is moved transversely to the longitudinal axis of the finished profile 15 in order to feed the finished profile 15 to its curing. For this purpose, heat can be generated within the clamping device 23 or the clamping device 23 can be guided through a curing channel. In this regard, reference is made to the description of FIG. 8.
  • FIGS. 4 to 6 show, for example, details of the design of the individual roller table 17 (see FIG. 1).
  • This roller table consists of individual rollers 34 which are spaced apart from one another by rotating shoes 35. These circular shoes 35 are known in their spatial shape. In the subject of the invention, it is advisable to form them from steel because they have to be resistant due to the curing temperature.
  • the rollers 34 are supported on the press ram 16 (see FIG. 1).
  • the rollers 34 act on the pressing jaws 3 to 6 and consequently allow them rolling friction with low frictional resistance.
  • the roller tables 17 as rotating roller tables (cf. FIG. 1).
  • the circulating shoes 35 must be articulated to one another. In the example in FIG. 4, the joint 36 is shown symbolically.
  • FIGS. 5 and 6 show that the edges of the circulation shoes 35 projecting beyond the rollers 34 are guided on guide strips 37 of the press rams 16 so that they cannot escape in the direction of the press jaws 3 to 6.
  • the joints 36 can be formed by appropriate shapes in the area of the lugs 38, as are common, for example, in bracelets.
  • the design of such roller tables 17 is known per se, which is why no further explanation is required. It is essential that the rollers 34 are connected to one another at a constant distance, but their connecting means are designed to be articulated. This makes it possible to guide the roller tables 17 in a form-fitting manner and to design them all around.
  • roller tables 24 which are arranged in the area of the tensioning stations 23 (FIG. 3).
  • guide walls 33 extend along the slides 26, 27, which have the purpose of covering the end faces of the finished pressed profiles 15, while these are being moved along the rails 25 with the aid of the clamping devices 23. In this way, an end expansion or crumbling of the finished profiles 15 is avoided. However, since the profiles 15 shrink in the course of the progressive hardening, there is only slight friction when the clamping devices 23 are laterally displaced.
  • the lateral pressing jaws 3, 4 are moved back into the starting position according to FIG. 7, as a result of which the finished pressed profile 15 is given the required degree of freedom, with the aid of the lower pressing jaw 5 and the associated pressing die 16 , 18 to be raised to the position shown in FIG.
  • the finished pressed profile 15 enters the shaft 40, which is located between the counter pressure bar 13 and the end wall 39.
  • the pre-pressing tool 9 is shifted into the position which is moved to the left in the drawing. While the pre-pressing tool 9 is now shifted to the right in the drawing, a pre-pressed profile blank 2, on the one hand, comes into the position of the shaft 20 above the pressing chamber 1.
  • the finished profile 15 which is lifted upwards, is moved laterally into the side by the same movement Position shown in Figure 1 shifted.
  • a piston 43 with an end plate 44 (or more) reaches through corresponding bores 42 of the slide 41 and pushes the finished pressed profile 15 out of the shaft 40 in the direction of arrow 46.
  • the piston 43 is connected to a stroke generator 45, which can be flange-mounted on the guide 7, for example.
  • the bores 42 are larger than the pistons 43 in accordance with the stroke of the slide 41.
  • the tensioning device according to the embodiment of Figure 8 is resilient on all sides.
  • a clamping frame 47 is used (ver same figure 8), which receives the end-pushed unit 3 to 6, 15.
  • this is supported on springs 51 on a chassis 50, insulation 48 and a circumferential outer wall 49 being located between the clamping frame 47 and the chassis 50.
  • Heating elements 52 are arranged within the clamping frame 47, which have the task of curing the profile 15 accommodated in the clamping frame 47.
  • the tensioning device 23 also has roller tables 24 (see FIG. 3).
  • a clamping device 23 If a clamping device 23 has now received a finished pressed profile 15 with its pressing jaws 3 to 6, the chassis 50 is moved transversely, so that a new clamping device 23 comes to rest on the front side of the pressing chamber 1. Accordingly, a plurality of such clamping devices 23 can receive such finished pressed profiles 15 and feed them for curing. However, as soon as a profile 15 has hardened, its tensioning device 23 is moved again in front of the pressing chamber 1 according to FIG. 3, so that the stroke generator 31 with its pressing disk 32 can push the units 2 to 6 and 15 back into the pressing chamber 1. From there, the ejection movement of the finished profile 15 takes place in the sense of the representation according to FIG. 7.
  • chassis 50 according to FIG. 8 can also be divided into several chassis, it being possible to convey these individual chassis in curing ovens and to retrieve them after the profiles 15 have hardened.
  • FIGS. 9 and 10 A variant of FIGS. 3 and 8 results from FIGS. 9 and 10. Thereafter, the unit consisting of the pressing jaws 3 to 6 and the finished pressed profile 15 is pushed off in a rotating roller table 53 which is supported on roller table beds 54.
  • This roller table 53 can be located, for example, within a curing channel 55.
  • the pressing jaws 3 to 6 can be provided with toothed rings 56, on which toothed wheels 57 act, several of which can be arranged within the hardening channel 55.
  • the problem with this embodiment variant is to return the pressing jaws 3 to 6 back into the pressing chamber 1. This can be done through well-known funding programs.
  • the strength of the profile 15 produced within the scope of the exemplary embodiments essentially depends on how the structure of the small parts is directed in the region of the pressing chamber 1. This alignment of the small parts is already brought about in the transfer from the metering device 8 according to FIG. 1 into the shaft 20.
  • the invention assumes that small parts, preferably aligned parallel to the longitudinal axis of the profile 15, are to be pressed. How this can be achieved is not the subject of this invention.
