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 and a method for producing a flat bar.
- 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. There are bends at the transition from the
- 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.
- Sidewall that is arranged at a bend.
- the outwardly facing side of a bending edge has a concave shape in its longitudinal direction.
- 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. It is another object of the present invention to provide a flat bar and a method for producing 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 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.
- Movement direction 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 for play-free attachment of the shoe on the lid head.
- 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.
- 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 pushing is machinable 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 side facing away from the corresponding lid head on the dei support surface. Then it is advantageous if the height of the
- 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. For this purpose, 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.
- the lid head may have a recess for receiving a holding portion of an endless belt for supporting the lid head. In this way, a secure attachment of the lid head on the endless belt can be realized. Further advantages of the invention are described in the following exemplary embodiments. Show it:
