Problems solved by technology

In addition, the use stability of permanent magnetic alloy products is very good. In the environment of high stress, there is no obvious decrease in intrinsic coercive force, and the weight loss in corrosive environment is also acceptable in a small range.
But this process has no polishing process

specific Embodiment approach 1

[0037] As shown in the figure, a preparation process of a permanent magnet alloy material, the process includes the following steps:

[0038] Step 1, the middle part of the permanent magnet alloy shaped as a square cylinder is punched to obtain the initial material;

[0039] Step 2, placing the holes on the multiple raw materials upwards and placing them in a row in the permanent magnet alloy material preparation device;

[0040] Step 3, polishing the upper end faces of multiple primary materials;

[0041] Step 4, polishing the front and rear end faces of multiple primary materials;

[0042] Step 5, polishing the lower end surfaces of the plurality of primary materials;

[0043] Step 6, polishing the left and right end faces of multiple primary materials to obtain finished materials;

[0044]The preparation process of the above permanent magnet alloy material also includes a preparation device for the permanent magnet alloy material; the device for the permanent magnet allo...

specific Embodiment approach 2

[0046] As shown in the figure, the preparation device of the permanent magnet alloy material also includes a frame 303 and a clamping plate I 304. The front and rear ends of the push table 3 are respectively fixed with a frame 303, and the outer ends of each frame 303 are integrally connected. There is card board I 304. The amount of initial material is small, and after polishing one initial material to generate centrifugal force, the initial material will squeeze the other initial material to rotate, and then the initial material will move, resulting in poor polishing effect. After the electric telescopic rod I302 is raised, the jig 303 drives the clamping plate I304 to rise, and then the two clamping plates I304 are respectively attached to the front and rear ends of the raw material, so that the raw material does not rotate and is stabilized during polishing. The upper end surface of the pallet Ⅰ304 should be lower than the upper surface of the original material at the high...

Abstract

The invention relates to preparation of permanent magnet alloy, and concretely relates to a preparation process of a permanent magnet alloy material. The process comprises the following steps: 1, punching the middle part of a permanent magnet alloy in a square cylinder shape to obtain initial materials; 2, placing the multiple initial materials in a permanent magnet alloy material preparation device in a manner that holes in the plurality of initial materials face upwards and are arranged in a row; 3, polishing the upper end faces of the multiple initial materials; 4, polishing the front end faces and the rear end faces of the multiple initial materials; 5, polishing the lower end faces of the multiple initial materials; and 6, polishing the left and right end surfaces of the multiple initial materials to obtain the finished product material.

Description

technical field [0001] The invention relates to the preparation of permanent magnet alloys, in particular to a preparation process of permanent magnet alloy materials. Background technique [0002] For example, the preparation technology of a kind of Nd-Fe-B series rare earth permanent magnetic alloy material whose publication number is CN107993828B mainly includes the following steps: (1) batching, (2) smelting, (3) crushing, (4) compression molding, (5) ) sintering, (6) heat treatment. Through the unique and advanced preparation process of the invention, combined with the unique permanent magnet alloy material system, the permanent magnet alloy products that meet the process and raw material composition of the present invention have a significant increase in intrinsic coercive force and no obvious residual magnetization The phenomenon of decline, and the squareness of the demagnetization curve is also very ideal. In addition, the use stability of permanent magnet alloy p...
