Description
Technical Field
The invention relates to the technical field of soft magnetic materials, in particular to a nanocrystalline soft magnetic material pressure forming device.
Background
Nanocrystalline soft magnetic materials are a novel class of soft magnetic materials, usually amorphous strips prepared by a roller method, and if annealing heat treatment is carried out on the amorphous strips, crystallization can be started, and the internal tissues are changed from amorphous to crystalline; at present, a nanocrystalline soft magnetic material is generally used for preparing a soft magnetic core, a soft magnetic coil or a soft magnetic body in a compression molding mode.
When preparing the soft magnetic core, preparing alloy powder composed of iron, nickel, cobalt and other elements, and uniformly mixing the alloy powder with a proper amount of additives (such as plasticizer) to form a mixture; then placing the mixture into a mold for pressing so as to press the mixture into a soft magnetic core with a required shape; and finally, demolding the pressed soft magnetic core from the mold, sintering at high temperature to realize combination and densification among alloy powder particles, grinding, magnetizing and the like, and preparing the soft magnetic core by using the soft magnetic material.
However, at present, there are some problems in the compression molding of the soft magnetic core, along with the development of technology, a lot of optimization is performed on the compression molding of the soft magnetic core by a person skilled in the relevant field, for more accurate comparison, for example, chinese patent publication No. CN111463005A discloses a powder molding machine for soft magnetic core production, which includes a shaft sleeve, a turntable is fixedly sleeved in the middle of the outer side of the shaft sleeve, a limiting ring is fixedly sleeved at the bottoms of two shaft sleeve inner rings, an upper pressing rod is movably sleeved at the inner ring of one upper limiting ring, a lower pressing rod is movably sleeved at the inner ring of the other lower limiting ring, a pressing rod push rod is movably connected at one side, away from each other, of the upper pressing rod and the lower pressing rod, a pressing table surface is arranged below the shaft sleeve, and three annular through holes are formed in the pressing table surface, and a first die, a second die and a third die are fixedly sleeved at the middle of the three annular through holes respectively.
When the prior art is used, powder is filled into the first die, the second die and the third die and pre-pressed, then the upper pressing rod and the lower pressing rod uniformly move upwards until the upper pressing rod reaches the first die, the second die and the third die, the upper pressing rod is started to push the upper pressing rod and the lower pressing rod to approach each other to compact the preliminarily formed special-shaped powder column between the upper pressing rod and the lower pressing rod, and meanwhile, the turntable drives the limiting ring to rotate, vibration is formed on the periphery of one side of the upper pressing rod and the periphery of one side of the lower pressing rod, impact force is formed to compact the powder while the powder is extruded, and the problem that faults occur in finished products is avoided.
However, the above prior art has some drawbacks in the process of press molding the soft magnetic core:
1. Although the powder can be pressed through the mutual approaching of the upper pressing rod and the lower pressing rod, the space for containing the powder in the first die, the second die and the third die is a cylindrical cavity, so that the powder can only be pressed into a cylinder shape, and the soft magnetic cores which cannot be processed according to the needs of the first die, the second die and the third die are replaced, so that the soft magnetic cores of different types cannot be processed, and the limitation exists.
2. Because the powder needs to be uniformly mixed before compression molding, powder particles can be combined and densified and have certain strength, and the powder can only be filled into the first die, the second die and the third die in the prior art, and cannot be fully mixed, the phenomenon that a finished product after compression is lack of binding force and is defective is easily caused, and the molding effect of the soft magnetic core is affected.
3. After the compaction of the powder column is finished, the upper pressing rod and the lower pressing rod are required to be controlled to be away from each other and pulled out of the first die, the second die and the third die respectively, so that the powder column can be taken down and the powder to be pressed is filled, automatic feeding of the powder can not be realized, and a large amount of working time is required to be consumed for frequently pulling out the upper pressing rod and the lower pressing rod, so that the working efficiency is affected.
Therefore, under the above-stated viewpoints, there is room for improvement in the conventional press molding means of the soft magnetic core.
