Definitions
- the invention relates to a device and a method for Sharpening wire ends.
- From DE-OS-2061949 is a method for sharpening wires known by resistance heating, in which the wire is clamped between two fixed points of a traction device, in which the wire is heated and stretched, with the wire as far is heated until the tensile strength against the tensile strength in the cold state significantly subsides and a stretch and a uniform rejuvenation without visible constriction the wire enters, with the wire thereafter or simultaneously for generating a predetermined breaking point on a section undergoes additional heating, with the wire on this site also locally stretches and rejuvenates, and the Stretching by the pulling action is carried out until the Tear off profile at the predetermined constriction.
- DE-OS-2061949 a device for implementation the aforementioned method known.
- This device has a jaw and a Switzerlandklemme on which a Voltage for the resistance heating of the clamped wire is created.
- the tension clamp is with a hydraulic Pulling device connected.
- JP 02133112 is a device for sharpening Wires known in which a heater is provided, and at the one extending through this heater wire to two Clamping points can be fixed. One of these two clamping points is on a rotatably mounted traction device intended.
- the invention is therefore based on the object, a device to provide for sharpening wire ends, which cost is manufacturable, a fast and burr-free tips allows the wire ends and flexible for different Use wire diameter.

- the second Contact point is particularly preferred to the first receiving device arranged so that they are in the case of Axialbewegige this receiving device also axially moved and in the case of a rotational mobility of the second receiving device a circular path follows.
- this load of the heated or glowing area In particular, it can be effected that the wire first rejuvenated and then tears off. In this rejuvenation or Tearing off creates a wire tip.
- the design of the wire tip as well as the length of the sharpened area may vary on different Way be influenced. For example, the Distance of electrical contact points can be varied, or the voltage of the resistance heating or the temperature, which the heater is generated in the wire, or the heating time, in particular in combination with the size and duration of the im Wire generated force or otherwise.
- the first contact point is on a clamping element arranged the clamping device of the first receiving device, so that the electrical contact point is pressed against the wire when the clamping element loads the wire.
- a second contact point is preferred on the second clamping element of the clamping device of the second receiving device arranged.
- the clamping element preferably has a thread in which it is guided.
- the first receiving device and / or the second Receiving device designed as a clamping device, and indeed such that wires of different diameters or different Cross-sectional geometry can be clamped.
- the device according to the invention can be used for sharpening different Wire materials are used, such as Superconductors, CrNi, nickel silver, or for wires from other Materials.
- the device according to the invention can also be used for wires with a wide variety of Cross-sectional profiles, such as three-, four- or polygonal or round or otherwise shaped cross-sectional profiles be used.
- the device according to the invention can be used in a wire drawing machine integrated or a separate device, for example can be moved on rollers or the like.
- the device according to the invention can be used in particular for sharpening used by wires, which are drawn in coarse draw lines should be, with the wire diameter preferably in Range are between 2 mm and 8 mm. But also for others Wire diameter, the device according to the invention is preferred.
- the second receiving device which is preferably a second has electrical contact point, relative to the first Receiving device by means of a drive device, such as motor or the like, or be moved manually.
- the object is further achieved by a method for sharpening of wire ends according to claim 9.
- a wire a predetermined location is heated, in particular such that it glows reddish, and then at least in the area this point loaded in the direction of the wire longitudinal axis is, so that the wire first tapers and then tearing off to form a sharpened wire end.
- the wire is heated by means of an electrical resistance heater.
- the wire becomes sandwiched between two spaced apart locations, and heated in the or an intermediate region of these locations. Then the wire is loaded. For this purpose, a terminal point moved relative to the other nip. Hereby rejuvenated the wire breaks and tears to form a wire tip from.
- Fig. 1 shows a Anspitzvorraum 1 according to the invention with a Housing 10, a first receiving device 12 and a second receiving device 14.

- the lever 50 may rotate in the direction indicated by the arrow 52 be rotated, causing a rotation of the disc-shaped Carrier and thus a change in distance of the clamping member 34th effected by the clamping part 24. If the wire is a corresponding one Temperature causes this rotational movement without much use of force an extension of the wire, with the wire cross-section tapers and tears off to form a wire tip.
- Fig. 2 shows a sectional view taken along the line 2-2 Fig. 1 in rotated representation.
- the first clamping member 24 is by means of a thread 60 and by means of a counter-thread 62 connected to the component 64.
- a Rotation of the component 24 about its axis causes the as Jaw-acting end face 66 of the first clamping element 24, with appropriate direction of rotation, in the direction of the counter-jaw acting surface 68 is moved.
- the front side 66 is also an electrical contact point, which, what not shown is in communication with a transformer.
- Fig. 3 shows a sectional view taken along the line 3-3 Fig. 1 in a partially sectioned view.
- the second clamping part 34 has in its outer periphery a thread 80, which extends in a thread 82 of the component 84, so that, with appropriate direction of rotation, the end face 86 of this second clamping part 34, which also as the second electrical contact point acts, moved in the direction of the surface 88 can be, so that in the intermediate region 90 between this end face 84 and this surface 86 arranged wire can be clamped.
