Embodiment 1

[0074] Such as figure 1 As shown, the permeation device includes components such as a rotating tray 10, a rotating bracket 110, a heating chamber 20, and a cartridge 410.

[0075] The rotary bracket 110 is installed on the rotary tray 10 below it, and multiple rotary brackets are installed on the rotary tray 10 in a circular array, which can perform high temperature penetration on multiple magazines. The material of the rotating bracket 110 is heat-resistant steel. The rotating bracket 110 is integrated with the rotating tray 10 through a rotating mechanism 112, and the rotating tray 10 is provided with a hole, and a bearing is installed in the hole, and the rotating bracket 110 is installed on the rotating tray through the bearing.

[0076] See attached figure 1 and Figure 4 , a first transmission that drives the rotation of the rotating tray 10 is installed below it. A second transmission is installed below the rotating bracket 110 so that the rotation of the rotating b...

Embodiment 2

[0083] The working process of the infiltration method according to the present invention will be described in detail below by taking a sintered NdFeB magnet infiltrated with dysprosium fluoride and coated with dysprosium fluoride ultrafine powder as an example in conjunction with the accompanying drawings. Of course, those skilled in the art can also use the infiltration method of the present invention to perform relevant high-temperature infiltration operations on other magnets.

[0084] In the present embodiment, concrete technological process is:

[0085] In the charging stage, the annular array of sintered NdFeB magnets coated with dysprosium fluoride ultrafine powder is loaded into the cylindrical material box 410, and the magnets can be placed in a single layer or stacked in several layers in the material box 410. The rotary tray 10 and the rotary bracket 110 are lowered as a whole by a lifting mechanism, wherein the lifting mechanism may be powered by a hydraulic cylind...

Abstract

The invention discloses a permeation device and method. The permeation device comprises a heating chamber, a rotary tray, rotary brackets, material boxes, a lifting mechanism and a transmission device, wherein the heating chamber is provided with an annular groove, and the rotary tray is arranged below the opening end of the lower end of the heating chamber; the rotary brackets are mounted on the rotary tray; the material boxes are arranged on the rotary brackets; the rotary brackets and the material boxes can ascend and descend under the action of the lifting mechanism; the rotary brackets can rotate in the annular groove under the action of the transmission device and revolve around the center axis of the rotary tray. The permeation method comprises the steps of material charging, vacuum pumping, high-temperature permeation, cooling, material taking and other steps. By means of the permeation device and method, the condition equality of the magnet positions and the condition equality of the heating environment are both achieved, so that the uniformity of the temperature condition required by sintered magnets in the high-temperature permeation and air cooling process is satisfied, and the consistency of properties of products is guaranteed.

Description

technical field [0001] The invention relates to an infiltration device and method, in particular to an infiltration device and method for infiltration treatment on the surface of a magnet. Background technique [0002] Dysprosium infiltration and terbium infiltration technology on the surface is a new technology for surface treatment of high-performance NdFeB rare earth permanent magnets sintered into compacts. Dysprosium and terbium infiltration treatment on the surface of magnets in a certain depth range can significantly improve the temperature resistance and coercive force of magnets, and has been initially applied in the field of high-performance NdFeB rare earth permanent magnet manufacturing. [0003] Vacuum high-temperature infiltration furnace is a high-temperature vacuum furnace that can perform dysprosium and terbium infiltration heat treatment on the surface of sintered permanent magnets. The main structure of a common high-temperature vacuum furnace includes a ...
