Definitions

  • the present invention relates to a winding and cutting device for winding a wire onto a pin, in particular a connecting pin, for electrical coils and for severing the excess wire in one operation, with a stationary sleeve, within which a mandrel is rotatably arranged, one of which is towards it has an end face that is open toward the front and widened in the winding area, into which the pin dips during winding, the hole having a diameter at least in the winding area that corresponds at least to the winding diameter.
  • US-A-3244202 shows a winding and cutting device with a mandrel guided in a sleeve with an edge-open groove running parallel to the longitudinal axis of the mandrel and opening into an opening which is equipped with a cutting edge for severing a wire guided in this groove.
  • the sleeve has a notch or groove on its outer surface, namely in its area facing the end face, for the stationary holding of a wire end.
  • the mandrel contains a central bore which has an extension on the end face facing away from the opening, which is connected to the groove via an elaborately designed recess and is equipped with an edge which is intended to bring about a rectangular “shaping” of the wire.
  • This known device is intended for the winding of wires with a rectangular cross-section on connecting pins with a rectangular cross-section. For each winding process, the stripped wire end is guided through the groove in the mandrel and the insulated part is fixed in the groove, after which the actual winding process begins.
  • the present invention has for its object to provide a device of the type mentioned, by means of which the winding of a wire onto a pin and the removal of the excess wire residue are carried out in a single operation.
  • the device is also said to be at distances of the end pins of less than 10 mm, as z. B. can be the case with bobbins, can be used and are also characterized by such a small space requirement that several devices can be combined if necessary.
  • the invention provides for a winding and cutting device of the type mentioned at the outset that the sleeve and the mandrel have a slot which is open towards one end face and towards the lateral surface of the device and is directed towards the bore and is oblique to the central axis of the mandrel and sleeve exhibit.
  • These oblique slots can preferably be directed tangentially to the bore.
  • the mandrel with a drive for. B. coupled electric motor
  • the control is selected so that in the starting or starting position of the device, the oblique slots of the sleeve and the mandrel are aligned.
  • the device, the drive of which can be actuated by means of a foot switch, is, for. B. attachable to a workbench in such a way that it points towards the connecting pin.
  • the winding and cutting device has a stationary sleeve 2.
  • a mandrel is rotatably mounted within this sleeve.
  • the mandrel 1 has a central bore 3, which, as indicated at 4, is expanded at the end of the mandrel.
  • the length and the clear width of the bore and the extension 4 are determined by the maximum pin length, the diameter of the pin and the diameter of the pin including the wire, i. H. the so-called winding diameter.
  • the depth of the enlarged part 4 of the bore 3 depends on the desired winding length.
  • the mandrel 1 and the sleeve 2 each have an oblique slot 5 and 6, which is open toward one end side and directed toward the bore including the recess 4.
  • this device is as follows: First, the mandrel 1 and the sleeve 2 are conveyed to one another by a correspondingly controlled drive in a position in which the two oblique slots 5 and 6 are aligned. 3 and 4, a wire 11 is inserted into the oblique slots and z. B. a bobbin .. per 10 together with pin 7 in the direction of arrow B, such that the pin (see Fig. 4) dips into the bore 3.
  • a foot switch is a drive, not shown in the drawing, z. B. geared electric motor, the mandrel 1 moves in the direction of arrow A, the projecting wire end being sheared off at the cutting edge denoted by 8 in FIG wraps.
  • the length "a” determines the wire length remaining in the mandrel after shearing and thus also the number of turns of the wire around the connecting pin.
  • the mandrel After the pre-programmed number of mandrel rotations, the mandrel is stopped in the starting position, so that the oblique slots 5, 6 are again in an aligned position and finally the coil body 10 is wound together with it lifted the pin in the direction of the part C from the device.
  • the wire lies close to the connection pin, is wound tightly and there is no wire end facing outwards.
