    • 专利摘要:
    A flux concentrator has a pair of primary coils wrapped around a thin walled cylindrical portion of a secondary coil. The secondary coil has a conductive head at an end and the coil is slotted to generate a rapid high intensity axially acting flux at the head in response to a flow of current through the primary coils. A pulling force is generated as a result of a slow rise high amplitude current flow through one of the coils followed by a rapid rise reversed polarity current flow through the second primary coil.

    专利说明:

    the carcass is placed inside the conductor through the cylinder of the secondary coil and is adjacent to the working end of the head.
    In addition, both primary coils can be placed on the outer cylindrical surface a second time the coils are electrically disconnected by a protrusion and the second of them can rtpH to the projecting portion of the working end of the head. In addition, the second primary coil is laid in spiral grooves made on the cylindrical surface of the secondary coil.
    Fig. 1 shows the electrical connection of the device in Fig. 2, the working head, a section with a partial cut; in fig. 3 a section A-A in FIG. 2 in FIG. 4, the same with the arrangement of both coils on a non-visible surface of a cylinder; in FIG. 5 the same, when placing the second primary Hagushka in grooves; FIG. 6 shows a current lead: a working head,
    In the proposed device, the control flap 1 serves to control the operation of the detachable head 2, which is used to attract the conductor or part 3, Inside the control dial, the control or logic system 4, which initially creates a current with slowly increasing w-pulses and large amplitude This current flows through conductors 5 to the first primary coil, b, located in the head and wound around the secondary coil 7, ToKf rapidly increasing; supplied through conductors 8 to a second primary coil 9, also wound around a secondary coil.
    The working head consists of a secondary cat, made in the form of a hollow conductive cylinder having an axial slot 10, the blind end of the cylinder 11 is a working face of the g-tin. A diametrical slot 12 is made on it, connected to the axial slot by an extended section 13 and blocked by an object Fixed in the groove 15, the web is predominantly made of beryllium bronze, and the secondary coil 2 is made of copper. The first primary coil 6 is wound on the outer surface of the cylinder and filled with plastic.
    The second primary coil 9 may be located (FIG. 3) in the spiral undercut of the conductive insert 16p adjacent to the inner surface of the cylinder and its blind working end, or on the outer surface of the cylinder (as shown in FIG. 4). made on the cylindrical surfaces of the secondary spiral grooves o
    Tokopodvod working head made through a removable plate 17 {FIG. B). The ends of the first primary coil are led out into the socket 18, where guides 5 are placed, placed in a removable plate. The ends of the second primary coil 9 through the conductors 19 are connected to the socket 1 to 20, where the conductors 8 go through the plate
    The operation of the device is as follows.
    The working head is guided to an indentation on the part 3. When applying a pulsed current that slowly increases through the conductors 5 to the coil 6, a magnetic field is generated in the secondary coil 2, creating a current line; striving to push the part or material 3 away from the working head 11. However, due to the slow growth this field did not reach the years of deforming stress. The control system turns off the slowly increasing current and begins to supply a rapidly increasing current through the conductors 8 to the second primary coil 9. This current, which is out of phase in the relatively slowly increasing state, leads to a rapid subsidence of the field and creates a pulling electromagnetic force sufficient for deformation and pulling vm ooze At the same time, the treatment zone is clearly concentrated under the blind working end of the cylinder, which flows along its wall and then along the end bridge. The intensity of the magnetic flux in the treatment area is about 10 times greater than the surrounding magnetic flux.
