Definitions

  • the invention relates to a bar of a warp knitting machine with a body which has distributed in the direction of its longitudinal extension a plurality of fastening positions, wherein at least at some fastening positions each have a mounting geometry is provided.
  • a barre is an element of the warp knitting machine which extends in the direction of the working width of the warp knitting machine and may well have a considerable length. In a warp knitting machine with a working width of about 6 m ingots are used, which also have a longitudinal extent of about 6 m.
  • each bar must be secured in the warp knitting machine to elements that control the movement of each barre during a knitting process.
  • the body has several attachment positions.
  • Such attachment positions are usually provided with mounting geometries, which may be formed, for example, as an internal thread. Also, attachment positions are often provided for the attachment of the knitting tools on the body.
  • each barre must be accelerated and decelerated in one direction during a looping cycle and then accelerated and decelerated in the opposite direction. It is therefore anxious to form the body of the bar with the lowest possible mass.
  • the body is made of magnesium or a carbon fiber reinforced plastic. In order to ensure sufficient mounting options in these materials, you need separate threaded elements or other mounting counter-elements that must be installed in the body. This makes the production of such a bar more expensive.
  • the invention has for its object to provide a cost-producible Barre with high performance.
  • the object is achieved in a Barre of the type mentioned above in that the body is formed of an aluminum material and the mounting geometries are formed directly in the aluminum material.
  • Such a bar is relatively easy to produce.
  • the attachment geometries can be created directly in the body without the need for additional parts, such as threaded inserts.
  • An aluminum material unlike magnesium, is durable. About that In addition, the thread strength of aluminum over magnesium are higher. Aluminum or aluminum materials are also less expensive than magnesium or as carbon fiber composite materials.
  • the body is formed as an extruded part.
  • the body is thus produced simply by extruding the aluminum material and, if necessary, cutting it to length. This is a low cost manufacturing process.
  • the body has at least one continuous in the direction of the longitudinal extension reinforcing bar, are formed in the mounting geometries.
  • the areas in which fastening geometries are formed specifically stiffened.
  • the mounting length, ie the depth, can be accommodated with the fasteners in the mounting geometries can be increased.
  • the extruded part preferably forms a hollow profile arrangement.
  • the reinforcing strip can be created with the same during extrusion. It is thus integrally formed with the body, so that no additional steps are required for the attachment of the reinforcing bar.
  • the reinforcing strip is arranged in the interior of the hollow profile arrangement.
  • the exterior of the body may then be configured as desired for the use of the attachment locations. Nevertheless, the advantageous effect of the reinforcing strip is maintained, so that attachment of attachments or other elements of the warp knitting machine can be done with high reliability.
  • the hollow profile arrangement has at least two chambers, which are separated from each other by a connecting wall.
  • a high rigidity of the body can be achieved transversely to the longitudinal extent.
  • connecting wall connects two outer walls bounding the hollow profile arrangement to the outside.
  • the connecting wall then stiffens the body inside.
  • the connecting wall has a thickness which is smaller than a thickness of the outer walls.
  • the connecting wall is arranged so that it is acted upon in operation transversely to its thickness direction with forces, for example acceleration forces. Accordingly, it can be made relatively narrow in the thickness direction, so that an increase in mass through the use of the connecting wall remains within reasonable limits.
  • the connecting wall is connected to the reinforcing strip. This results in a particularly good stiffening of the body.
  • connecting wall in a direction perpendicular to the longitudinal extent of the connecting wall is connected to a central region of the reinforcing strip and at least one attachment geometry at least partially passes through the connecting wall.
  • the connecting wall is then no longer over part of its height over the entire length of the body, but it is interrupted by a mounting geometry or by several attachment geometries. But this has virtually no significant negative impact on the stiffening of the body.
  • At least some of the attachment geometries are designed as screw threads.
  • the introduction of a screw thread in the body made of aluminum material is relatively simple. You just have to create a hole and cut a thread. With the help of a screw thread can be a fastening with sufficient reliability accomplish.
  • fastening geometries are arranged offset from each other perpendicular to the longitudinal extent.
  • screw threads you can then use, for example, two adjacent screws for fastening or you can fixation geometries, which are arranged perpendicular to the longitudinal extent offset from each other, offset in the longitudinal direction to each other. This results in a great design opportunity for the body of the barre.
  • the bars are each shown in front view and partially in section.
  • the bars have a longitudinal extent which is directed perpendicular to the plane of the drawing.
  • Fig. 1 shows a bar of a warp knitting machine 1, which can be used, for example, as a slide bar.
  • the bar 1 has a body 2, which is formed of an aluminum material.
  • An aluminum material can be pure aluminum.
  • the aluminum material can also be an aluminum alloy in which the largest proportion of material is aluminum.
  • Such an aluminum alloy may, for example, have at least 80% aluminum.
  • the body 2 has in the direction of its longitudinal extension, that is perpendicular to the plane, several attachment positions 3.
  • mounting position 3 is provided with a mounting geometry 4, which is designed here as an internal thread.
  • the attachment geometry 4 is formed directly in the aluminum material of the body 2.
  • the body 2 is formed as an extrusion.
  • the body 2 is thus formed by extrusion, in which the aluminum material is pressed through a nozzle whose shape corresponds to the cross section of the body 2.
  • Fig. 2 shows a modified form of a bar 1, which can be used for example as a knitting needle bar.
  • the bar 1 has a body 2, which is also formed as an extruded or extruded profile of an aluminum material.
  • the body forms a hollow profile arrangement.
  • the body 2 has for this purpose a plurality of outer walls 5, 6, 7, 8, the two chambers 9, 10 enclose, which are separated by a connecting wall 11 from each other.
  • the connecting wall 11 connects two outer walls 6, 8 with each other.
  • the connecting wall 11 has a thickness which is smaller than a thickness of the outer walls 5-8.
  • a reinforcing strip 12 is arranged in the interior of the hollow profile arrangement. It is thus located on the inside of the outer wall 6, so it is not outside over the circumference of the body 2 before.
  • the reinforcing strip 12 extends in the longitudinal direction of the body 2. It can be produced together with the connecting wall 11 during extrusion in one piece with the outer walls 5-8. Accordingly, therefore, the connecting wall 11 and the reinforcing wall 12 made of the same material as the rest of the body 2 also.
  • the connecting wall 11 is connected to the reinforcing strip 12.
  • the attachment geometry 4 is passed through the outer wall 6 and through the reinforcing strip 12.
  • the mounting geometry 4 also passes through a part of the connecting wall 11, which is connected to a central region of the reinforcing strip 12.
  • the “middle region” here refers to a direction perpendicular to the longitudinal extension and parallel to the outer wall 6.
  • connecting wall 11 in the direction of the longitudinal extent is no longer over its entire height, ie the distance between the outer walls 6 and 8, by. This is for the rigidity of the body 2 but not critical.
  • the connecting wall is arranged to extend substantially in a direction in which the largest forces act during operation of the warp knitting machine.
  • the connecting wall 11 is thus stressed essentially to train or pressure, but not to deflection.
  • the connecting wall 11 can in the embodiment according to Fig. 2 can also be used as a stop for a screw to be screwed into the mounting geometry 4.
  • Fig. 3 shows another Barre 1, which can be used for example as Abtschkammplatinen-Barre. Also the Barre 1 after Fig. 3 has a body which encloses with outer walls 5-7 a plurality of chambers 9, 10, wherein the chambers 9, 10 are separated from each other by the connecting wall 11.
  • the reinforcing strip 12 On the outer wall 6, the reinforcing strip 12 is arranged.
  • the reinforcing strip 12 has a greater width than in the embodiment of Fig. 2 on, so that you can accommodate here two attachment geometries 4, which are arranged transversely to the longitudinal extent offset from each other.
  • the reinforcing bar 12 is disposed in the interior of the body 2, so that the outside of the body 2 can be kept smooth or may have a geometry that is adapted to the respective mounting situation.
  • Fig. 4 shows a fourth embodiment of a bar 1 with a body 2, which also has two chambers 9, 10, which are separated by a connecting wall 11 from each other.
  • An outer wall 6 is provided with a reinforcing strip 12 into which a fastening geometry 4, in the present case an internal thread, is introduced.
  • the length of the fastening geometry 4 can thus be thicker than the thickness of the outer wall 6.
