Definitions

  • the present invention is dot f. Improvement of wire for lintering, especially improvement of abrasion resistance of wire.
  • Figs. 1 and 2 show an example of a linter print head.
  • Fig. 1 is a sectional view and Fig. 2 is its exploded perspective view.
  • 1 is the first: 7° rate forming a common magnetic path
  • 2 is the plurality of cores adhering to said: 7° rate 1
  • 3 is f.
  • Rate, 6 is a spacer
  • 7 is a force at one end, connected in a ring shape, the second frame.
  • 8 is the plate panel 7' To tip 7 .
  • the hole 5a in the base 5 and the armature o fixed against the core 2 A pin 10 is a guide frame, and 11 is a pin guide attached to the tip of the guide frame 10 to guide the wire.
  • a guide member is formed by the arm 10 and the pin guide 11 .
  • the wires in the printing head H for the linter are guided by the pin guide 11 and aligned substantially in a line, but the portion fixed to the plate panel 7 is arranged in a substantially elliptical shape. It is designed so that it contacts the printing surface at an angle of about 1 inch during printing. The problem is that the whole becomes obscure. It is a ⁇ problem.
  • the present invention has been made to meet the above demands, and is a dot-f that is strong against impact and has little uneven wear.
  • the purpose is to provide a printer for a printer.
  • the present invention takes advantage of the toughness peculiar to metals, and uses this as a base material and coats the surface with a high-hardness, wear-resistant coating peculiar to ceramics.
  • the wire By coating the wire, it is characterized by being a wire for dot printers that is strong and has a long life with little uneven wear.
  • the metal material as the base material includes high-speed tool steel, die steel, other tool steel, tungsten, ⁇ 0Ano wire, etc. centre.
  • a known material for linter wire can be used.
  • high-speed tool steel high-speed steel
  • hard coating in the present invention various coatings known as hard coatings such as carbides, nitrides, borides, oxides, and carbonitrides of various metal elements can be applied.
  • good characteristics can be obtained when using ceramic films such as TiC, TiN, TiCIT, TiB2 , VC, and A1203 .
  • the thickness of the coating in the present invention is less than 1 Am
  • the thickness is set within this range because better characteristics can be obtained when the thickness is set within the range of 1 to 1 ⁇ . .
  • the structure of the coating is selected depending on the relationship between the base material and the coating material, but it is of course possible to have a single-layer or multi-layer structure . Adhesion of the film is extremely important, and for this reason, the chemical vapor deposition method (CVD method), molten salt method, and ions are used as coating methods. It is desirable to use the rating method, etc. Brief description of the drawing
  • Figures 1 and 2 are Dot F. A sectional view and an exploded perspective view of the printing head for linter, and FIG. This is a photomicrograph of the cross-section of the coating of the wire for the linter. Best Mode for Carrying Out the Invention
  • a high-speed steel wire for dot linter is ultrasonically cleaned in trichlorethylene and thoroughly degreased.
  • Fig. 5 shows a photomicrograph of the new surface of the coating of the linter.c From this figure, it can be understood that the coating adheres closely to the base material.
  • Table 1 shows various characteristics of the conventional wire and the wire of the present invention.
  • the dot-f according to the present invention As a result of the above practical tests, the dot-f according to the present invention.
  • the effect of improving the abrasion resistance of the wire for lintering is clear, and the wire according to the present invention also has good adhesion to the silver seal, and is suitable for panel panels. Fixation was also extremely easy and strong.
