Definitions

  • the invention is concerned with the production of writing tips for ink pens.
  • the invention has for its object to provide the writing tubes and cleaning wires of writing tips with a wear-resistant sliding surface, the mechanical resistance of which is the same as or close to that of the hard metal writing tubes, but economic production is ensured such that the production price is not essential is above the price of the usual stainless steel writing tubes.
  • writing tubes and cleaning wires can be relatively inexpensive Starting material made of stainless steel and can be tempered in a simple and inexpensive manner.
  • Writing tips with such writing tubes and cleaning wires are also ideal for use in automatic, computer-controlled drawing machines, plotters and labeling devices, with a surprisingly large writing length resulting in a flawless writing or drawing image even when using rough foils.
  • the pretreatment and also the aftertreatment of the writing tubes are of great importance.
  • the writing tubes must be cleaned of chips and other residues after machining.
  • cleaning baths which are usually acidic, and it has been shown that these baths contain free oxygen, which is the cause of later oxidation and can therefore lead to their being unusable.
  • cleaning is therefore carried out using alkaline agents.
  • the product marketed under the name "ROLLGLEEM” by the company “Wyandotte” has proven to be particularly useful.
  • the temperature is brought to 950 ° C. in a chamber furnace with a volume for approx. 6 reactor vessels. After reaching this temperature, 4 to 5 of the prepared reactor vessels are inserted.
  • the reaction time is approx. 30 to 40 min. During this time, a boron layer of 1 to 10 ⁇ m iron, chromium and nickel boride is created.
  • reaction vessels are cooled in an air stream at room temperature.
  • the cooling time is approx. 10 minutes.
  • One or more cylindrical drums made of natural rubber with an inner diameter of 50 mm and a height of 150 mm are used for the treatment.
  • the drums are placed vertically on a rotatable plate, at a distance of 60 mm between the plate axis and the drum axis, and carry out planetary rotary movements via a gear.
  • the tubes are cleaned of boron powder in an ultrasonic bath filled with distilled water.
  • the drums are closed with a lid.
  • the treatment speed is 200 rpm for the plate and 160 rpm for the drums - that is, planetary movement.
  • the treatment time is approximately 60 hours.
  • the treatment time is 1 hour to max. 10 hours depending on the wire diameter.
  • the original disc device is used to drum at the specified speeds.
  • the treatment is carried out at 200/160 rpm for 15 minutes.
  • the boron powder dissolves in the water during this treatment.
  • the drum is approximately 30 0 brought from the horizontal into an apparatus and the content as long rinsed under flowing water-Bendem until the Borstoff is completely removed.
  • an area 14 is identified by boundary lines 16, in which writing tubes 18 are arranged mixed with EKabor-1 granules or DURBORID-2 powder. Around this area 14, the g l ei che granulate or powder is not containing write pipes.
  • the height of the base layer below the boundary line of area 14 is 10 mm.
  • the lateral distance of the area 14 to the side walls of the container 10 is also 10 mm.
  • the height of the area 14 with the scraper bricks is 60 mm and above the area 14 the vessel is filled up to the top with the same powder.
  • the powder or granule masses surrounding the area 14 prevent the penetration of oxygen and ensure a uniform boronization of the writing tubes or writing wires arranged in area 14.
  • Fig. 2 shows the rotary drum assembly, which is used during the pretreatment and aftertreatment according to the rules described above.
  • This arrangement shown schematically in FIG. 2, has a turntable 20 which is supported in its central axis by a drivable shaft 22.
  • a drum 24 At the periphery of the turntable there is a drum 24, or several drums are rotatably mounted in bores of the turntable with their shafts 26 projecting downwards.
  • the shafts 26 carry gear wheels 28, each with an intermediate gear 30 Comb, which engages in a gear 34 which sits on a sleeve 32 surrounding the shaft 22.
  • the sleeve 32 can be stopped or driven relative to the shaft 22 at a different speed or direction of rotation, which results in a planet-like movement of the drums at an arbitrarily adjustable differential speed between the turntable shaft and the rotating drum shaft.
