Definitions

  • the present invention relates to a sliding block for a lid head of a flat bar of a carding machine which can be pushed onto the lid head in the axial direction, with at least one sliding section which can be arranged between the lid head and a flexible bend and which on the side facing the flex bend forms a sliding surface for interacting having the flex bend. Furthermore, the invention relates to a lid head, a flat bar.
  • the flat rod has at its outer end a mounting portion for axially sliding the sliding block.
  • a concave surface is arranged on a deliverable to a Flexbogen page. This surface follows the underside of the proposed shoe.
  • the height of which corresponds to the height of the mounting portion At both ends of the bottom side walls join, the height of which corresponds to the height of the mounting portion.
  • inwardly inclined portions are arranged, which surround the forward and the rearward upper edge of the flat bar.
  • the proposed shoe on additional locking or snap elements, which should prevent slippage of the shoe in the axial direction.
  • the proposed shoe consists of a stamped part of tempered phosphor bronze. This relatively thin stamped part receives its shape just described by appropriate bending. Bends are required at the transition from the bottom to the side walls and from the side walls to the top. Also, the bottom itself must be bent to obtain the said concave shape.
  • the optionally existing locking elements on the shoe must also be pressed apart depending on their design to allow sliding on the attachment portion on the flat bar.
  • the disclosed slip shoe rests only on its forward lower and rearward lower edges on the card fold. This results in only two linear sliding surfaces. This leads to poor sliding properties and high wear.
  • the effective effective sliding surface is just at the transition from the bottom to a side wall, that is arranged at a bend. Especially in the field of such a bend, it is not possible to produce a sliding surface with the required precision.
  • the outwardly facing side of a bending edge has a concave shape in its longitudinal direction. This means that the two axially extending sliding surfaces of the known sliding shoe in each case stand out from the flex bend. In other words, the shoe is in many cases only at its lower four corners on the flex bow.
  • Object of the present invention is thus to provide a shoe and a lid head for receiving the sliding shoe according to the invention, so that the disadvantages known from the prior art are avoided. Furthermore, it is an object of the present invention to provide a flat bar, which avoid the disadvantages mentioned.
  • the sliding portion of a sliding shoe according to the invention has, on the side facing the lid head, a contact surface which can be applied without gaps to a corresponding support surface of the lid head.
  • the sliding shoe preferably has a sliding surface which is flat. Since the radius of the flex bend in relation to the extension of the sliding surface in the direction of movement of the flat rod is very large, resulting for the contact of shoe and flex bend approximately those conditions that would arise if the flat shoe would slide over a newly formed guide surface. In particular, only slight deformations and stresses occur in the two bodies when the sliding section and the flex bend touch. Nevertheless, the calculable according to the Hertz formulas flattening leads to a relatively large actual contact surface between sliding section and flex bend. A flat sliding surface thus leads to improved sliding behavior of the shoe on the Flexbogen and to a defined leadership of the flat bar on the slide.
  • the sliding surface has a concave curvature whose radius is adapted to the radius of the flex bend.
  • the radii are identical. However, a certain deviation of the radii can be tolerated, provided that the resulting flattening leads to an actual contact surface between the sliding portion and the flex bend, which extends over a substantial part of the sliding portion.
  • the sliding surface can be manufactured with the aid of conventional methods, for example with cutting methods, in particular by grinding, with high precision.
  • the sliding shoe according to the invention can be fastened to the lid head with all known means.
  • a rivet or adhesive connection comes into consideration.
  • the sliding shoe is releasably attached to the lid head. To think about, for example, to screw or Verklipsen. This facilitates the replacement of a worn shoe.
  • a spring connection is particularly preferred.
  • a gripping portion of the spring portion is designed to cooperate with a step of the lid head.
  • the at least one spring section extends in the axial direction at least over the region of the sliding surface. This results in a particularly secure attachment of the shoe on the lid head.
  • the spring portion in cross section in the form of a hook is in particular the shape of a barb whose gripping portion corresponds with an inwardly inclined step of the lid head.
  • a lateral sliding of the gripping portion can be avoided.
  • the spring portion in the form of a round hook is particularly preferably, the spring portion in the form of a round hook.
  • the gripping portion of the round hook can also engage in an inclined step of the lid head.
  • the spring force results in an advantageous manner by an elastic deformation of the round portion of the hook. An elastic deformation of other portions of the shoe, in particular the sliding surface, can be avoided, which leads to a particularly firm and secure attachment of the shoe on the lid head.
  • the at least one spring section is biased by being pushed onto the lid head.
  • the spring force is thus generated by the fact that the spring portion is elastically deformed when sliding the shoe on the lid head.
  • the sliding block may have bevels on its head end facing the flat bar.
  • Chamfers may for example also be provided on the spring portion, so that the preloading is facilitated.
  • At least one latching element is provided for fixing the sliding shoe in the axial direction.
  • a locking element is designed to cooperate with a counter-locking element on the lid head.
  • the latching element can be, for example, a cam, which engages on a counter-latching element designed as a recess.
  • Such a pairing of locking element and counter-locking element results in a particularly tight fit of the sliding block on the lid head.
  • a bar arranged in the axial direction for preventing play between the sliding block and the lid head with respect to the direction of movement of the flat bar is present.
  • the strip may rest against an edge of the spring portion and for biasing the spring portion by a Contribute to excess. Overall, the bar contributes advantageously to play-free attachment of the shoe on the lid head.
  • the shoe is integrally formed.
  • it may be designed as a precise casting or exactly as a milled part.
  • the sliding shoe or at least the sliding surface is made of plastic. Its use is characterized by its low weight, good machinability and advantageous sliding properties.
  • the sliding surface are preferably added slip additives, such as carbon or Teflon. As a result, a particularly smooth running of the shoe on the flex bend and a low wear of the flex bend and the shoe is effected.
  • the sliding portion has a thickness such that the sliding surface is machinable.
  • the thickness of the sliding portion results from the distance of the sliding surface to the contact surface.
  • the sliding surface can be made very precise.
  • a blank produced, for example, as a cast or milled part can be machined with high precision in one or more machining steps.
  • the sliding surface preferably has at least one cleaning groove.
  • Cleaning grooves are used to absorb impurities, such as grains of sand, which are located on the flex bend. This avoids that hard particles are trapped between the sliding surface and the flex bend. If the cleaning grooves are arranged at an angle, dirt particles are removed from the flex bend very quickly. Overall, an improved life of the flex bend results.
  • the shoe is designed so that the resulting form-fitting and frictional connection with the lid head without additional bonding is sufficiently strong to hold the loads occurring during operation stand.
  • the required load capacity can be determined by an appropriate selection of material and shape of the shoe and the Cover head are guaranteed. Of particular importance here is the design of the spring and locking elements.
  • the shoe is designed so that the positive and frictional connection with the lid head is so strong that the sliding surface after being machined cutting without the shoe separates from the lid head or by the resulting during processing Forces elastically or plastically deformed.
  • a corresponding design of the shoe can be dispensed with an additional bonding here.
  • a support section for positioning the cover head during machining of a section of the flat rod is provided on the corresponding cover head.
  • the height of the sliding shoe over the contact surface is less than the distance of the support surface facing boundary plane of the support portion of the support surface. This ensures that the one or more support sections are not covered by the deferred sliding block.
  • the support portion may be used to position the flat rod with the slide shoe slid on for the purpose of machining in the receptacle of a processing machine. For example, it is possible to use the support section in the machining of the sliding surface of a newly plugged sliding block.
  • this support section when newly assembled Kardieretti the flat rod, such as after a wear-related replacement, machined, for example, sanded, should be. Since the support section has a defined position with respect to the first mounted part of the flat bar, is then a particularly precise positioning of the newly assembled part possible, so that this receives a well-defined position with respect to the first mounted part.
  • the shoe has a U-shaped cross-section, wherein the at least one sliding portion is arranged at the base of the U's.
  • the lid head then preferably has a cuboid or box-shaped cross-section, which is at least partially located between the legs of the U's of the slide shoe after sliding of the slide shoe. This results in a particularly strong connection between the shoe and lid head.
  • the sliding shoe may each have a sliding section on its side pointing in the direction of movement and on the opposite side. As a result, tilting of the flat rod about its longitudinal axis can be avoided when sliding over the flex bend.
  • Each of the sliding surfaces is formed as a plane by itself. The sliding surfaces can be inclined against each other, but this is not necessary because of the relatively large radius of the flex bend as a rule.
  • a said spring portion is advantageously arranged on both legs of the U's. It is preferred if the gripping portions of the spring portions formed on the legs facing inward and engage respectively at a said, preferably inwardly inclined step of the lid head. This results in a particularly strong and secure connection of shoe and lid head.
  • the legs each have a toothed section on the head end facing the flat rod which, in cooperation with a respective toothing of the cover head, prevents bending or deformation of the respective leg pointing in particular outwards. This feature also contributes to a tight fit of the shoe on the lid head.
  • the lid head according to the invention is designed to slide on a sliding shoe according to the invention in the axial direction.
  • it has a shape corresponding to the sliding shoe.
  • At least one support section is preferably provided on the side facing away from the at least one sliding surface of the sliding shoe. Then, during machining of the sliding surface of the slidable sliding block, the flat bar can be positioned precisely relative to a processing machine.
  • the lid head has an outer section in the form of a box for pushing on the sliding block.
  • one step can be provided for engagement of a respective gripping section of the sliding block on a side pointing in its direction of movement and on an oppositely pointing side.
  • Such a step is particularly preferably arranged in a middle section of the outer section between a support surface for applying a contact surface of the sliding shoe and the reference plane.
  • the side facing away from the support surface of the lid head is not covered by the deferred sliding shoe. This is of particular advantage when the sliding surface of the already deferred sliding shoe is to be machined.
  • the top of the lid head can be used to support an endless belt for supporting the lid head.
  • the lid head has at a pointing in the direction of movement end and at an oppositely facing end depending on a support surface in each case to support a contact surface of the sliding block.
