In this embodiment, the working principle of the magnetic concentrator is as follows: the diameter of the coil hole 8 is 50mm, the length is 100mm, the distance from the central axis of the working hole 7 is 60mm, the length of the working hole 7 is 46mm, the diameter is 19mm, the width of the narrow slit plane 42 is 0.3mm, 16 turns of a solenoid coil 9 (copper wire of 5 x 7) with the outer diameter of 45mm are inserted into the coil hole 8, then a connecting terminal 5 (DL 95 aluminum nose) is clamped into the positioning sleeve 36, the positioning sleeve 36 is inserted into the working hole 7, the capacitance of the forming machine is 125 muF, the discharging voltage is set to be 16kv, the capacitor is charged, the switch is closed, the solenoid coil 9 is discharged, an induced current (i 1) is induced on the surface of the coil hole 7, then the current flows to the working hole 8 through the narrow slit, the width of the working hole 8 is smaller than the width of the coil hole, the current is superposed, the intensity of the induced current is strengthened (i 2), the magnetic field is correspondingly strengthened, and the induced current (i 3) is induced on the workpiece, as shown in fig. 15, the generated lorentz force reduces the diameter of the workpiece.
In this embodiment, the hole grooves 71 at both ends of the working hole 7 have the same aperture and depth, and the through hole 72 is a cylindrical through hole; the magnetic collector 4 is made of chromium zirconium copper.
It should be noted that the structure of the working hole 7 may also be as follows: (1) one of the hole grooves 71 at both ends of the working hole 7 can be deeper than the other hole groove to form an offset working area; or the aperture of one hole groove is larger than that of the other hole groove, so as to form a working area with different apertures at two ends. (2) The through hole is a circular truncated cone-shaped through hole to form a circular truncated cone-shaped working area, and for pipe fittings in circular truncated cone shapes, the structure of the circular truncated cone-shaped working hole can be adopted, so that a better forming effect is achieved. (3) Two slots can also be circular truncated cone-shaped slots with large end faces and small bottoms to form a working area with two ends as bell mouths, and for some workpieces with special structures, the structure can be adopted to achieve a better forming effect.
In this embodiment, the operation includes the following steps:
step S1: putting the solenoid coil 9 into the coil hole 8 of the magnetic collector 4, inserting the positioning sleeve 35 into the working hole 7 of the magnetic collector 4, and then inserting the connecting terminal 5 from the right end of the positioning sleeve 36;
step S2: clamping the end part (flat plate shape) of the wiring terminal 5 through the wiring terminal clamp 6, then taking the positioning sleeve 36 out of the working hole 7 of the magnetic collector 4, and then moving the wiring terminal clamp 6 to enable the wiring terminal 5 to extend into the working hole 7 of the magnetic collector 4;
step S3: inserting the cable 2 into a mounting hole (cylindrical) of the terminal block 5, and then clamping the cable 2 by the cable clamp 3;
step S4: the solenoid coil 9 is discharged, eddy current is formed in the working hole 7 of the magnetic collector 4 by the discharged solenoid coil 9, induced current is induced on the wiring terminal 5 by the eddy current in the working hole 7, and the induced current generates radial force on the wiring terminal 5 to reduce the diameter of the wiring terminal 5 and deform to form interference fit, so that the wiring terminal 5 is firmly connected with the cable 2.
The invention has the advantages that:
(1) because the used coil is a solenoid coil, when the solenoid coil works, the force on the solenoid coil is directed to the axis of the solenoid coil in the radial direction, so that the outer layer insulating material of the coil is not easy to damage, and the service life of the coil is greatly prolonged;
(2) the wiring terminal is a special-shaped piece, and the wiring terminal can be well positioned and clamped through the device, so that the forming quality is better ensured;
(3) the coil volume can be greatly reduced, and the production cost is reduced;
(4) the clamping of the wiring terminal and the cable is simpler and more convenient, and the working efficiency is greatly improved.
