Definitions

  • the invention relates to a shaft rod and a heald frame and a method of manufacturing a shaft rod, wherein such a heald frame especially for fast-running Looms is provided.
  • a shaft rod for this purpose has formed as a hollow body support rod to which a Carrier part for the heddle support rail connects.
  • the support rod consists of two levels, essentially parallel to each other arranged sheet metal strips, which on their upper longitudinal edges a longitudinal rod with a rectangular cross section are connected.
  • a sheet metal part is arranged on its lower longitudinal edges, that connects them and carries the heddle support rail.
  • the one so enclosed Interior is filled with honeycomb Structure filled out.
  • the disadvantage of a shaft rod of this type is the accumulation of material at the connection points of the shaft rod with the Carrier rail and the associated increase in weight, as well the complex and expensive connection technology e.g. in the form of Laser welding.
  • the achievable strength also depends largely on the resilience of the existing Connection points.
  • heald frames To connect heald frames to the side supports, used next to other, detachable corner connections.
  • heald frames such as proposed in DE 41 01 512 C1 and DE 196 25 076 C2 are, these corner connections are according to DE 4038384 C2 reinforced to support forces from the side supports to transfer to the shaft rods. This will make the crowd of the overall system, which has a performance-limiting effect.
  • the shaft rod according to the invention is preferably as a profile body formed as a metal profile body, being a in use the upper and a lower narrow side in use has, between which at least one side wall, preferably but two side walls are arranged.
  • the side wall has a changing wall thickness in the longitudinal direction of the shaft. For example, the wall thickness at the near-end areas of the Sidewall relatively large while in between middle area is significantly reduced. The reduction of Wall thickness of the side wall in the middle area affected the bending strength of the shaft rod is not decisive. The weight however, is significantly reduced. With the same weight comparable shaft rods with a non-weakened side wall and weakened side wall have a higher bending stiffness on. At the ends of the shaft rod is the side wall however somewhat more trained. This creates enough here Possibility in a simple and inexpensive way To attach side supports to two shaft rods and at least two side supports to produce a heald frame. The on the thicker side wall allows the end areas easily Introduction of the required forces into the shaft rod.
  • the side wall is preferably uninterrupted, i.e. formed without openings, openings or the like, wherein these are not excluded.
  • the shaft rod is also preferably formed in one piece.
  • the reduction in thickness the side wall can be achieved in one milling operation, for example in which a protruding over the other side surface Part of the side wall is milled off or if it is a little more difficult Procedure also a corresponding deepening in the otherwise flat side wall is milled.
  • the metal profile is preferably an extruded aluminum profile, the longitudinal one Encloses cavities.
  • the aluminum extrusion profile initially has the same cross-section everywhere. Only by removing the cross section is partially changed.
  • the shaft rod can be used in the press shop relatively inexpensive pressing tools and relatively thick Wall thicknesses are produced. Only then are the side walls milled thinner than the presses press the walls could reduce the weight of the shaft rod, while maintaining its rigidity. At the shaft rod ends however, the walls are not milled off. Through this The shaft rod ends have a special cross-sectional structure stable.
  • the profile body that the Shaft rod forms to manufacture and with thin wall thickness to apply flat reinforcements to the ends of the ends, For example, stick on to increase the wall thickness here.
  • a wall thickness that changes in the longitudinal direction can also be so of the side walls can be reached.
  • one or more crossbars are formed which cover the side walls connect with each other and a buckling the same under prevent dynamic load.
  • crossbars it is also possible to use the one between the side walls Foam the interior completely or partially or with fill other lightweight components, such as honeycombs or the like.
  • the side walls of the hollow chamber profile are preferably offset slightly to the outside against an upper full profile area, where the offset is less than the wall thickness. At the complete milling of this offset occurs on the sides thus flat surfaces, the side walls not being broken through become. This gives manufacturing advantages because of Full profile area can be used as a reference surface.
  • a heald frame 1 is illustrated in FIG Use in high-speed weaving machines is provided.
  • the heald frame 1 forms a rectangular frame in which the healds 2 are held in parallel in large numbers.
  • the healds 2 each have a thread eye 3 through which the warp thread of the weaving machine is running.
  • the heald frame 1 serves this purpose the warp threads for shedding in the work cycle of the weaving machine to move up and down.
  • the heald frame includes two shaft rods 4, 5 which are spaced apart are arranged parallel to each other and at their respective Ends 6, 7, 8, 9 by side supports 11, 12 with each other are connected.
  • the shaft rods 4, 5 are essentially mutually equally trained. It is representative of both therefore illustrated in Figure 2, the shaft rod 4 and below explained in more detail.

  • a hollow chamber profile is included two longitudinal, approximately rectangular interiors 13, 14 or, like the slightly modified embodiments according to FIG 3 and 4 illustrate, with three interiors 13, 14, 15 educated.
  • One or more transverse webs 16, 17 are correspondingly present, which run lengthways, the interiors 13, 14, 15 from each other separate and side walls 18, 19 of the profile body with each other connect.
  • the wall thickness of the crossbars 16, 17 is less than the thickness of the side wall 18, 19 and thus contributes to Weight saving at.
  • the essentially flat side walls 18, 19 are arranged parallel to one another and face upwards in a full profile area 21 over which the profile above a strip-shaped, flat narrow side 22 completes.
  • the wall thickness is greater than the thickness of the crossbars 16 or 17. Through the increased wall thickness becomes the profile end and thus the corner connection strengthened.
  • An extension 24 closes on the wall 23 which, as illustrated in FIG. 2, has one or more openings 25, 26 may have to reduce the weight.
  • the extension 24 is used to fasten a mounting rail 27 to which the healds 2 are attached and thus fastened.
  • the profile of the shaft rod 4 is not uniform.
  • On its end 6 and its end 7 are the side walls 18, 19 based on strip-shaped adjoining the narrow side 22 Surface areas 28, 29 of the side wall offset outwards, see above that on both side walls 18, 19 surface projections delimited by steps 31, 32 are formed. These are flat plateaus, where the thickness or wall thickness A ( Figure 2) the side wall 19 as well as the side wall 18 is relatively large. For example, it can be in the range between 1 mm and 2 mm. It is preferably 1.3 mm.
  • the width B of the interiors 13, 14, as well as the width of the interior 15 in the Embodiments according to Figures 3 and 4 is less than that Width C to measure between the surface areas 28, 29 is.
  • the inner one, oriented parallel to the side wall 18, 19 Wall 33, 34 is thus to the respective surface area 28, 29 parallel inwards.
  • the surface areas 28, 29 lie in imaginary levels between the respective walls 33, 34 and the outside of each side wall 18, 19 by the same run.
  • the surface projections 31, 32 are in particular on the steps to be pointed towards each other by parallel to each other running straight steps limited, which are perpendicular to the longitudinal direction L stand. But it is also possible to incline the steps to arrange or to form arrow or arch. Moreover can also use a gradual change in wall thickness instead of a step be provided.
  • the wall 33, 34 is not completely flat, but how can be seen from FIGS. 3 and 4, but also for Figure 2 applies, it goes by means of a rounded step 35, 36 into the narrow side 22, 23 over.
  • This stage 35, 36 is in the exemplary embodiment S-shaped, but otherwise everyone else is Shapes e.g. elliptical transitions possible.
  • the bridge 16, 17, on the other hand, is only the same with a rounding or similar shape in the side walls 18, 19 over. If necessary, However, appropriate levels can also be provided here become.
  • the end region of the shaft rod 4 points in the exemplary embodiment each have a length D of approximately 60 mm. This applies for the end 6 as for the end 7.
  • the length of these end areas is determined depending on the type of drives that are on attack the end areas. It can e.g. also 150 mm long his.
  • the surface projections are between the two end regions 31, 32 removed for example by milling.
  • the sidewalls 18, 19 are in the intermediate section available here 37, 38 just trained. By removing the two side walls 18, 19 becomes a wall thickness in the intermediate section 37, 38 E received, which is much less than the wall thickness A. This is done by comparing the illustration on the right shown in Figure 2 with the left representation. Likewise goes this is evident from a comparison of FIGS. 3 and 4.
  • the wall thickness E is preferably less than 1 mm. It lies preferably at 0.35 mm to 0.6 mm.
  • the extensive removal of the Surface projections 31, 32 leave flat side walls 18, 19 with the mentioned thin wall.
  • the surface areas 28, 29 can serve as orientation and guidance areas, in order to remove the surface projections 31, 32 over a large area not to cause excessive weakening of the side walls 18, 19.
  • an optimized profile has a width C. of 9 mm, a width F (measured between the outer sides of the Surface projections 31, 32) of 10.5 mm, an inner width B of 7.9 mm and a wall thickness E of 0.55 mm.
  • the surface projections 31, 32 are not milled off anywhere there, where forces in or out of the shaft rods 4, 5 become. This affects the shaft ends, possibly the middle of the shaft, if drive elements or connecting rods are arranged there become. Stiffening plates for corner connectors at ends 6, 7, 8, 9 of the shaft rods are unnecessary. In many cases middle connectors can be dispensed with. Banding in the tissue is avoided. It can with the invention Process wall thicknesses A can be achieved using the extrusion process otherwise hardly, at least not with reasonable Make effort.
  • the web 17 and / or the web 16 can in particular on the Ends 6, 7, 8, 9 are removed to make the interiors 13, 14, 15 to unite with each other.
  • the higher chamber thus created can serve to accommodate a corner connector.
  • the full profile area 21 to the ends 6, 7, 8, 9 to mill the weight of the shaft rod 4 or 5 additionally reduce without affect the rigidity of the shaft rod concerned. It is also possible to use the full profile area instead 21 to provide a U-shaped profile area, the two in extension of the side walls 18, 19 of the profile in Vertical direction H ( Figure 2) has legs extending away. These, too, can be milled down to the ends 6, 7, 8, 9 become.
  • Figure 5 illustrates a modified one for the above Description using the same reference numerals applies accordingly.
  • the extruded aluminum profile of the shaft rod 4 In contrast to the shaft rod 4 or 5 as described above, is the extruded aluminum profile of the shaft rod 4, however, initially over its entire length been milled through continuously. The increase in wall thickness of the side walls 18, 19 in the adjoining the ends 6, 7 End areas were created by gluing reinforcement plates 44, 45, 46 reached. It will be the same Conditions reached as with the heald frame 4 described above, in which the end regions of the milling process of the side walls 18, 19 have been exempted.
  • the gluing of reinforcement plates is also with a shaft rod possible, as illustrated in Figure 2, 3 or 4 has been, for example, in a Middle area or in another milled area again reinforcement is required.
  • the described shaft rod 4 is based on an extruded aluminum profile with relatively thick side walls, which in some areas removed and thereby made thinner. This can without significantly affecting the rigidity of the Stock rods happen, but this saves a lot of weight is achieved.
  • the material removal can be the local load conditions be adjusted. For example it is possible at the ends or other points of force application leave un weakened thick walls while the remaining areas the side walls are milled so far that a uniform thinner wall thickness is achieved. It is beyond that possible to measure the amount of material removal in several stages or to vary continuously.
  • the material removal affects one Reduction of the wall thickness, which is transverse to the direction of movement of the Shaft rod is measured.
  • the profile height of the Shaft rods e.g. by suitable milling e.g. elliptical arc of the full profile area to the ends 6, 7 varies be measured in the direction of movement H.
