型化する欠点があつた。 Conventionally, it has been proposed that cold working (swaging) is performed to improve the magnetic properties of a magnetic material, thereby producing large anisotropy and improving the magnetic properties. This is thought to be due to the alignment of the axis of easy magnetization in the processing direction, which improves the squareness of the demagnetization curve. However, processing such as swaging is static and its effect on improving magnetic properties is relatively small, and pressurization usually requires ultra-high pressure on the order of tons/cm 2 to carry out the required processing. , the high pressure generator, the pressure treatment equipment, etc. had the disadvantage of increasing in size.

ことを特徴とするものである。 The object of the present invention is to solve the above-mentioned drawbacks and to efficiently perform a treatment for improving magnetic properties without requiring a large-sized pressure treatment device. When pressurizing the molded magnetic material in a magnetic field, a device for applying static pressure to the magnetic material and a sonic or ultrasonic vibration device are provided coaxially with the pressurizing device to apply static pressure to the magnetic material. This feature is characterized in that the vibration pressure and vibration pressure are applied in a coaxial manner in a superimposed manner.

るよう考慮されている。 Explaining the following with reference to an embodiment of the drawings, 1 is a frame constituting a processing container, 2 is a magnetic material inserted into the processing container, and pressurized from above and below with pressure members 3 and 4 interposed above and below. . Reference numeral 5 denotes a pressure punch to which ultrasonic vibrations generated by a vibrator 6 are propagated through a horn 7. Numeral 9 is a hydraulic cylinder that applies static pressure to the vibrator 6, and 10 is a lower fixed punch. The magnetic material 2 is held between the upper and lower punches 5 and 10 and is vibrated and pressurized. 11 and 12 are magnetic poles that apply a magnetic field at right angles to pressurization, and magnetically permeable members 13 and 14
It is considered that the generated magnetic flux can effectively act on the internal magnetic material 2 through the inner magnetic material 2.

性を向上させるようになる。 The magnetic material 2 in the container 1 to be processed is formed by rolling forging, casting, sintering, etc., and is subjected to pressure processing in a magnetic field formed by magnetic poles 11 and 12. For pressurization, the punch 5 is driven by the cylinder 9, and the magnetic material 2 to be processed is held between the upper and lower punches 5, 10 via the pressurizing members 3, 4, and low static pressure is applied. In this state, the vibrator 6 is excited by the oscillator 8 and generates high frequency vibrations such as sonic waves and ultrasonic waves, which propagate through the horn 7 and act on the magnetic material 2 from the punch 5 . Therefore, since static pressure and ultrasonic vibration are superimposed on the magnetic material 2, the effect of the ultrasonic vibration becomes remarkable, and ultra-high pressure vibration can be applied by reducing the ultrasonic output.
Through this pressure treatment using ultrasonic vibration, the magnetic material 2 is subjected to compression-release vibration pressure, which more effectively causes volumetric contraction and generation of strain, and magnetizes due to the mutual effect with the magnetic force acting at the same time. The alignment of the easy axes can be gradually and easily performed with high efficiency by vibration pressure, and the magnetic properties can be improved.

の向上処理効果が極めて高い。 Conventionally, when subjected to high-pressure shock treatment in a short period of time in cold processing, compression pressing occurs before the magnetization axes are sufficiently aligned, which has the disadvantage that magnetic properties cannot be sufficiently improved. However, by applying ultrasonic vibration pressure, the orientation of the spins is gradually aligned, and this can be done very effectively and with high efficiency, so that the effect of improving the magnetic properties is extremely high.

るものである。 For example, in the treatment of Fe-6%Co-18%Cr material, after solution treatment, multi-stage aging treatment was stopped at 400°C and pressure treatment using ultrasonic vibration was performed. The vibration is approximately 1 to 3 vibrations with a width of 6 to 10μ and a frequency of 20 to 25KHz.
Performed under static pressure of Kg/mm 2 , wave height approximately 100Kg/
The treatment was carried out in such a manner that vibrating pressure of approximately mm 2 could be applied, and a magnetic field of 10 KOe was applied perpendicular to the pressure. Through this magnetic property improvement treatment, the maximum energy product of the magnetized magnet was approximately 4.6 MGOe.(B.H)max. On the other hand, the same material was subjected to multi-stage aging treatment after solution treatment (B.
H) max was approximately 3.8 MGOe, confirming the excellent effects of the present invention. The time required for this multi-stage aging treatment was about 6 hours, whereas the present invention required a treatment of about 13 minutes, which was effective in efficiently improving magnetic properties in a very short period of time. In the above example, the pressure treatment using ultrasonic vibration was performed in a heated state of 400°C during the aging treatment, but a high effect can be obtained even if the pressure treatment is completely cold, that is, at room temperature. .

から実用的に極めて効果が大きい。 In the present invention, when a magnetic material formed by casting, sintering, or further forging is subjected to pressure treatment in a magnetic field, static pressure and vibration pressure are coaxially superimposed on the magnetic material. As a result, processing can be carried out extremely easily and with high efficiency, and the intended treatment for improving magnetic properties can be easily obtained using a relatively simple device without using a large ultra-high pressure generator. Vibrations are not limited to ultrasonic waves, but can also use sound waves and ultrasonic waves from around several 100 Hz, as well as high frequency vibrations of several 100 KHz. The treatment time by this vibration pressurization is much shorter and more efficient than the conventional aging treatment, which takes several hours, so it is extremely effective in practice.

The working magnetic field may be a pulsed or alternating magnetic field. During the pressure treatment, heat treatment such as in a furnace, energization, high frequency, etc. may be superimposed.

Furthermore, a magnetic layer obtained by coating a base material with a magnetic material by an appropriate method can also be treated in the same manner.
