Definitions

  • the invention relates to a knitting machine part and a method for its production.
  • the knitting machine part has a plurality of tool guides which are arranged next to one another in a straight line or next to one another in a circumferential direction about an axis.
  • the knitting machine part can be, for example, a knitting cylinder, a needle bed of a flat knitting machine, a dial, or a sinker ring. In particular, it can be both a cylinder for a single jersey machine and a cylinder for a double jersey machine.
  • Such knitting machine parts are subject to wear when operating a knitting machine.
  • wear can occur.
  • the knitting machine part is made from a non-hardened metallic material and then hardened in at least one section. Because the at least one hardened section of the knitting machine part cannot be worked or can only be worked with great effort.
  • Induction hardening e.g. GB 735 378 A
  • the workpiece to be hardened is heated by induction and then rapidly cooled, which increases the hardness of the material.
  • Induction hardening of a knitting machine part is not easy due to its size.
  • the section-by-section hardening of the knitting machine part can, for example, result in areas which have already been hardened being tempered again by hardening immediately adjacent areas. This tempering reduces hardness and the goal of increasing hardness is not achieved uniformly everywhere.
  • US 3 545 233 A1 describes a knitting machine part according to the preamble of claim 1.
  • the knitting machine part has several tool guides. Each tool guide is set up to guide a knitting tool in one direction of movement along the relevant tool guide. Exactly one knitting tool is preferably assigned to each tool guide.
  • the knitting machine part can have a first group of tool guides and a second group of tool guides for further knitting tools.
  • circular knitting cylinders can have tool guides for knitting machine needles in the circumferential region and tool guides for sinkers at one axial end.
  • a knitting machine part can thus have tool guides for a single group and / or type of knitting tools (for example in the case of a double jersey cylinder) or for at least two groups and / or types of knitting tools (for example in the case of a single jersey cylinder).
  • Each tool guide has a hardened area with a hardness that is greater than the hardness of at least one other, unhardened area of the tool guide.
  • the tool guide is therefore not hardened everywhere, but only in a hardened area, which is subject to particularly high stress during operation of the knitting machine. In this particularly stressed area, the hardness is increased in order to reduce wear on the knitting machine part.
  • the majority of the existing hardened areas is achieved by hardening the knitting machine part made of a non-hardened metallic material at least in sections. These hardened areas are integral areas which are each formed integrally without a seam and joint with the at least one unhardened area of the associated tool guide. Only a significantly smaller number of hardened areas is designed as a non-integral area. In a non-integral area there is at least one and preferably exactly one separate hardened component Formation of the hardened area arranged, which is fixedly connected to the knitting machine part. The connection is preferably made by an adhesion promoter connection or a material connection.
  • all hardened areas are designed as non-integral areas with a separate component, while all other hardened areas are designed as integral areas.
  • all other hardened areas are designed as integral areas.
  • at most 0.1% or at most 0.2% of the hardened areas can also be designed as non-integral areas.
  • a hardened separate component is attached there.
  • the effort for reworking and arranging the separate component is great.
  • the preferably inductive hardening of the tool guides after the manufacture of the knitting machine part from unhardened material is considerably more economical.
  • the desired hardness may not be achieved in every tool guide.
  • Separately hardened components are specifically arranged on the knitting machine part on these tool guides. As a result, an effective manufacture of the knitting machine part is possible and it is ensured that each tool guide has a hardened area with the required material hardness in order to keep the wear of the knitting machine part low.
  • each non-integral area has exactly one separate component. As a result, the effort required to form the hardened areas, which are designed as non-integral areas, can be minimized.
  • Each tool guide preferably has a contact surface for the knitting tool.
  • at least a portion of the contact surface is arranged in the hardened area.
  • the section of the support surface arranged in the hardened area forms a hardened surface section.
  • the hardened surface section can be produced in the integral area by hardening the material and thus a structural transformation. In a non-integral area, the hardened surface section can be formed by a component surface of the arranged component.
  • the component surface forming the hardened surface section has a surface width in a transverse direction perpendicular to the direction of movement of the knitting tool that is smaller than the tool width of the knitting tool. It can thereby be avoided that thread sections guided on the knitting tool come into contact with the transition point between the hardened component and the adjacent, less hard material of the knitting machine part. This configuration is particularly important when the component is used as an insert in a recess and there is thus an interface or edge between the inserted component and the recess in the transverse direction adjacent to the component surface or to the hardened surface section.
  • the surface width should preferably be at least 80% of the tool width.
  • each tool guide has two side webs which delimit a guide channel with a channel width for guiding the knitting tool in the transverse direction, perpendicular to the direction of movement of the knitting tool.
  • the channel width is the width of the guide channel between the mutually facing side web surface sections which are used to guide the knitting tool.
  • the channel width can be, for example, the minimum width of the guide channel between the side webs.
  • a difference between the channel width and the tool width results in a guide play and the sum of the surface width and the guide play is smaller than the tool width.
  • the area width is smaller than the channel width.
  • the guide play can be up to about 0.07 mm in a preferred embodiment, but is usually less than 0.1 mm.
  • the at least one component is preferably inserted in a non-integral area in a receiving recess on the knitting machine part.
  • the component can therefore be designed as an insert.
  • the component can be arranged completely in the recess or partially protrude from the recess.
  • the knitting machine part can be closed in a ring in a circumferential direction and form an annular disk or a cylinder or hollow cylinder.
  • the tool guides can be arranged essentially parallel to the axis and / or radially to the axis. For example, one group of tool guides can be aligned axially and another group of tool guides can be aligned radially.
  • a group of tool guides can be set up to guide knitting needles.
  • Another group of tool guides can be set up to guide boards.
  • the two groups can be present on the same or on different knitting machine parts.
  • the knitting machine part with the tool guides is made from an uncured metallic material. Subsequently, at least a section of the knitting machine part is hardened using a hardening process, in order to produce at least a majority of the tool guides with a hardened area which, as an integral area, merges with the adjacent, unhardened material of the knitting machine part without a seam or joint.
  • the hardening can be carried out, for example, by induction hardening.
  • one or more inadequately hardened areas are identified by one or more tool guides.
  • a recess is created and a separate component is inserted into each recess.
  • the components are firmly connected to the respective recess in the receptacle, for example by means of an adhesive connection.
  • FIG. 1 two exemplary embodiments of knitting machine parts 15 are illustrated in perspective.
  • the knitting machine part 15 from FIG. 1 is a knitting machine part 15 which is closed in a ring in a circumferential direction U, for example a circular knitting cylinder.
  • the embodiment of the knitting machine part 15 shown is a needle bed of a flat knitting machine.
  • the knitting machine part 15 in the sense of the present invention can also be ribbed disks, sinker rings or other knitting machine parts 15 which have a plurality of tool guides 16 for guiding a knitting tool 17 which can be moved in one direction of movement B.
  • FIGS. 3 and 4 schematically illustrate tool guides 16 for a knitting tool 17, the knitting tool 17 being formed, for example, by a machine knitting needle.
  • the knitting tool 17 can also be a board, as shown in FIG Figure 10 is shown by way of example.
  • the tool guide 16 in the exemplary embodiments described has two side webs 18 arranged at a distance in a transverse direction Q, perpendicular to the direction of movement B.
  • the two side webs 18 delimit a guide channel 19 arranged between the side webs 18.
  • the guide channel 19 is, for example, at right angles to Direction of movement B of the knitting tool 17 and perpendicular to the transverse direction Q on one side delimited by a support surface 20 which is arranged on a base body 21 of the knitting machine part 15.
  • the bearing surface 20 can also extend partially outside the guide channel 19.
  • the side webs 18 project from the base body 21.
  • the guide channel 19 is open, for example. Contrary to the contact surface 20, the guide channel 19 can also be closed, at least in sections, in modified exemplary embodiments.
  • Each guide channel 19 or each tool guide 16 has an end 22, viewed in the direction of movement B of the respective knitting tool 17, which is assigned to a location or an area of the knitting machine part 15 in which a stitch formation takes place.
  • the knitting tool 17 is moved in the direction of movement B along the tool guide 16 and in particular is moved or pushed out over the end 22 of the respective tool guide 16 in order to receive a thread section outside the tool guide 16 or outside the guide channel 19 or in cooperation with other knitting tools to form a stitch.
  • each tool guide 16 of the knitting machine part 15 has a hardened area 30 starting from the end 22.
  • the material of the respective tool guide 16 has a greater hardness than in one itself unhardened area 31 adjoining hardened area 30.
  • the material of knitting machine part 15 or tool guide 16 may be the same in hardened area 30 and in unhardened area 31, but may have different microstructures, resulting in different hardnesses.
  • the hardened area 30 is formed as an integral area 30a in the majority of the tool guides 16 of the knitting machine part 15. This means that the hardened, integral region 30a merges into the unhardened region 31 without a seam and joint.
  • a transition zone 32 can be present between the hardened integral area 30a and the unhardened area 31, in which the hardness increases from the unhardened area 31 to the hardened area 30.
  • the hardened integral area 30a is illustrated by cross hatching. In the schematically illustrated transition zone 32, the cross hatching is shown less densely in order to schematically represent the hardness decreasing towards the unhardened area 31.
  • the hardened areas 30, which are designed as integral areas 30a, are present in the vast majority of the tool guides 16, preferably in at least 90% or at least 95% or at least 98% of the tool guides 16 of the knitting machine part 15 made of an uncured material and then cured in the portion of the tool guides 16 following the ends 22 to form the cured integral areas 30a in a curing process.
  • This hardening can, for example, by induction hardening using an inductor for heating and a cooling device for rapid cooling. As a result, a change in the structure of the material and consequently greater hardness can be achieved in the hardened integral region 30a.
  • individual hardened areas 30 can be formed by hardened, non-integral areas 30b, as is schematically shown in FIGS Figures 3, 5, 6 and 8 to 10 is shown.
  • a hardened separate component 33 is arranged at the location of the tool guide 16 where greater hardness is desired.
  • the hardened component 33 is preferably designed as an insert part 34 and inserted into a receiving recess 35 on the tool guide 16.
  • the separate hardened component 33 can be arranged entirely within the receiving recess 35 ( Figures 3, 5 and 8 until 10 ) or be arranged only partially in the receiving recess 35 and protrude out of the receiving recess 35 ( Figure 6 ).
  • the receptacle cutout 35 is produced on a tool guide 16 which does not have sufficient hardness following the respective end 22, and the already hardened, separate component 33 is then inserted into the receptacle cutout 35 as an insert part 34.
  • the hardness therefore changes abruptly between the component 33 or insert 34 and the adjoining non-hardened area 31 or at least insufficiently hardened area of the tool guide 16 ( Figure 3 ).
  • the hardened non-integral area 30b is therefore predetermined by the shape of the component 33 and clearly delimited without a transition zone.
  • the support surface 20 extends into the respective hardened area 30 to the end 22 of the tool guide 16, so that the support surface 20 forms a hardened surface section 36 in the hardened area 30.
  • the hardened surface section 36 is formed by a component surface 37 of the arranged component 33 or of the insert part 34 inserted into the receiving recess 35.
  • the hardened surface section 36 of the support surface 20 can extend in sections or completely in the guide channel 19 between the side webs 18 and / or in sections or completely outside the Guide channel 19 may be arranged ( Figure 6 ).
  • the component 33 or insert part 34 is connected to the base body 21 of the knitting machine part 15, preferably by means of an adhesion promoter connection or in another suitable manner, in particular in a material connection.
  • the component surface 37 which forms the hardened surface section 36 in a non-integral region 30b, has a surface width bf which is smaller than the tool width bw of the knitting tool 17.
  • the tool width bw of the knitting tool 17 is again smaller than the channel width bk of the guide channel 19.
  • the difference between the channel width bk and the tool width bw forms a guide play between the knitting tool 17 and the tool guide 16.
  • the sum of the surface width bf and the guide play is smaller than the tool width bw.
  • Figure 9 the difference ⁇ between the surface width bf and the tool width bw is also illustrated.
  • the guide play between the knitting tool 17 and the tool guide 16 or the guide channel 19 can be approximately up to 0.07 mm in a preferred embodiment.
  • the surface width bf can preferably be at least 80% of the tool width bw.
  • the knitting tool 17, in particular the knitting machine needle can be set up to guide a thread section 45 and at least partially into the guide groove 19 to draw.
  • the guide groove 19 following the end 22 can have a correspondingly widened area in which, for example, thread cutouts 46 are introduced into the side webs 18 (compare in particular Figures 7 and 8th ).
  • This expanded area does not serve to guide the knitting tool 17 and therefore does not define the channel width bk effective for guiding the knitting tool 17.
  • a knitting machine part 15 can also have a first group 50 and a second group 51 of tool guides 16.
  • the tool guides of the first group 50 guide the assigned knitting tools 17 in a first movement direction B1 and the tool guides 16 of the second tool group 51 guide the assigned knitting tools 17 in a second movement direction B2.
