Definitions
- the invention relates to a method for producing stitching wire for use in the graphic industry for stapling magazines, brochures u. Like., wherein a pullable wire made of a starting material in a first drawing stage from an initial diameter to an intermediate diameter is pulled and the wire in a second drawing stage from the intermediate diameter to a final diameter, so that the stitching wire results.
- the primary material that usually has an initial diameter of about 5.5 mm, in a first drawing step to an intermediate diameter of about 2.2 mm. Subsequently, this wire is annealed, after a subsequent Galvanizing level to the desired final dimension, which is usually is in the range of 0.3 to 0.7 mm to be wet-drawn.
- the stitching wire produced by the known methods is after the second drawing stage finally wound up and delivered to the graphics industry.
- the graphic industry are present printing houses u. like. meant which is the stitching wire for stapling magazines, brochures u. Like. Use.
- the Wire in the printing shops is successively drawn off the coil or the spool and cut. Then cut the pieces of wire bent so that individual brackets result, which are then in the Spines of the individual magazines are stapled.
- the stitching wire is whole has certain properties. This includes that the wire is relative on the one hand is said to be hard to easily pierce the backs of magazines to be able to, but on the other hand can also be easily formed into a bracket should. It is also necessary that the wire or the wire made therefrom Staples hold their shape after stapling, so do not bend back, which not only affect stitching, but also injuries can lead if a reader over the top of a bracket with the Hand drives. There is another essential requirement for the stitching wire in that it can be cut well. It is important when cutting that Do not form so-called flags at the cut end of the wire. This is from the actual cut end face protruding pointed areas. These flags can cause the stitching wire when stapling does not pierce the spine vertically, but is inclined with the result that correct stapling is not possible.
- the object of the present invention is now a process for the production of stitching wire to provide that easy and inexpensive feasible and with which a wire can be produced, which in the graphic Industry requirements easily met.
- the previously specified and derived task is in a method of at least initially solved according to the invention in that that the wire has an initial diameter during the drawing process to a final diameter is not subjected to heat treatment.
- the invention has surprisingly been found to be used to manufacture one that meets the requirements of the graphics industry Stitch wire not only suffices, but that even a wire with improved Properties will be provided if throughout No heat treatment is provided.
- heat treatment does not only result in a shortening the production time of the wire, there are also reduced Manufacturing costs, since the heat treatment has a not inconsiderable share of costs of the total manufacturing costs.
- the stitching wire according to the invention is also very hard, which in particular when stapling thick magazines is very important. This can be compared a thinner wire is used in the prior art, what is cheaper.
- the stitching wire according to the invention can be cut very well so that there are no flags of the type described above Kind of result. This can obviously be explained by the fact that the after wire produced using the method according to the invention is almost brittle can be called, so that when cutting the wire a smooth Cutting surface without flags results.
- the invention Process leads to very good results on wires where the starting material has a relatively low carbon content of less than 0.1 %, in particular less than 0.06% by weight.
- a starting material can be used which has a cross-sectional decrease from the starting diameter to the final diameter of allows more than 80%, preferably more than 99%. Based on the Diameter, the diameter can be reduced to a factor of 100.
- a wire with an initial diameter is usually used as the initial material of less than 10 mm used.
- Wires with an initial diameter of approximately 5.5 mm are used.
- the Final diameter should be less than 1 mm and is currently in practice depending on the customer-specific requirements between 0.7 and 0.3 mm.
- the stitching wire according to the invention preferably a metallic coating as surface finishing applied.
- this can be used as an intermediate coating provided between the first and second drawing stages become.
- the intermediate coating before re-drawing in the second drawing stage leads to a stitching wire on which the coating is particularly adheres well if the staples are made from the staple wire and these in the magazines, brochures and.
- the coating like. Be introduced. in principle but it is also possible to use the coating as a final coating to apply after the second drawing stage. But this sets a special one Clean the wire beforehand to ensure that the coating adheres well Ensure wire.
- the first drawing stage carried out in the dry drawing process becomes.
- the second drawing stage can be carried out in the wet or else in the dry-drawing process.
- the wire is used in the wet drawing process guided through a bath before and / or while pulling.
- a is preferred Dry lubricant is used to lubricate the wire when pulling to achieve.
- a dry lubricant in the first drawing stage, after the first drawing stage and before the Coating a surface cleaning of the wire with the aim of at least essentially complete removal of the dry lubricant perform.
- a mechanical Cleaning can be done.
- the Winding wire at least once between the first and second drawing stages. This ensures that the first and second drawing stages can be carried out independently of one another, that is, on the one hand it is not necessary to use both drawing stages in terms of drawing speeds to coordinate with each other. On the other hand, it is also manufacturing technology favorable to keep the two drawing stages separate from each other, because in the event of failure one drawing stage the other can be operated easily.
- the individual process steps namely the first drawing stage, the coating stage and the second drawing stage are independent process stages, between each of which the wire is wound to ensure independence of the individual stages.
- a pullable wire serves as the starting material A. has possibly been descaled beforehand mechanically and / or chemically. Subsequently is the starting material A in a first drawing stage B with a Draw a plurality of drawing dies to a smaller intermediate diameter. The drawn wire is then coiled in stage C. In connection the wire is then annealed in step D, i. H. a heat treatment subjected. Immediately afterwards, the wire is galvanized in step E.
- the steps can D and E can also be separate steps, between which the wire again is coiled or wound.
- stage E the wire in stage F is rewound again and then fed to the second drawing stage G, where the wire on the desired final dimensions is tightened, so that in stage H a coiled stitching wire h with the desired final diameter results.
- a good drawable wire with a low carbon content serves as the starting material 1, which, if necessary after a previous cleaning, is fed to a first drawing stage 2 for descaling in a cleaning device.
- the wire of the starting material 1 has an starting diameter D 1 .
- the wire of the starting material 1 is drawn onto a wire with an intermediate diameter D 2 .
- a first drawing device with a plurality of drawing dies with decreasing diameters is provided. While the initial diameter D 1 of the wire in the present case is approximately 5.5 mm, the wire after the first drawing stage 2 has an intermediate diameter which usually varies between 1.4 mm and 3.2 mm.
- the wire is then in stage 3 via an appropriate winding device wound. Then the wire wound in stage 3 Metallically coated in stage 4, for which purpose a corresponding coating device is provided.
- the wire is used for surface finishing galvanized. Basically, it is also possible to use levels 2 and 4 in a line, so without winding in stage 3.
- the previously wound wire over a appropriate winding device reeled off and through an appropriate bath the coating device where it is electrolytically galvanized. In principle, hot-dip galvanizing would also be possible. Then will the galvanized wire was rewound in step 5.
- the galvanized wire with the intermediate diameter D 2 is then fed to a second drawing stage 6, the end product of which is the stitching wire 7 with the desired final diameter D 3 .
- a second drawing device with a plurality of drawing dies with decreasing diameters is provided.
- the stitching wire 7 is then wound up again via a corresponding winding device, which happens in step 8.
- a steel with a low carbon content, in particular less than 0.06% by weight, should be used as the starting material 1, in order to ensure good pullability of the starting material 1, so that in any case a sign of the wire from one Output diameter D 1 from 5.5 mm to 0.2 mm to 0.7 mm is easily possible.
- the first drawing stage 2 is in the dry drawing process performed during the second drawing stage 6 because of the previous one Surface finishing carried out in the wet drawing process becomes. Drying usually uses an appropriate one Dry lubricant ahead.
- a stage 9 (Fig. 3) for surface cleaning the wire for preferably complete removal of the drying agent.
- Fig. 4 a stress-strain diagram is shown, on the one hand the stress-strain properties of the stitching wire according to the invention 7, on the other hand, the corresponding properties of a known Process manufactured stitching wire h are shown.
- the inventive stitching wire is harder, but lasts pronounced after bending well its shape.
- the stitching wire according to the invention can be 7 also cut very well, so that problems when stapling magazines and. The like. Do not have to be feared.
- the values of the diagram given on the abscissa are only for a preferred one Embodiment of the produced by the inventive method Wire apply, but other value ranges also without further ado possible are.
