Description

Technical Field

[0001] The utility model relates to the technical field of rare earth alloy experimental equipment, in particular to a rare earth alloy sample preparation anti-oxidation device. Background Art

[0002] At present, when rare earth alloys are tested, the rare earth alloy samples are generally prepared by manually pounding the samples in a pounding pot. During the pounding process, the surface area of ​​the alloy sample continues to increase as it is pounded, and because the existing pounding pot is open, external oxygen will continue to oxidize the alloy sample, which has a great impact on subsequent sample performance tests. At the same time, in this pounding method, the force needs to be appropriate. If it is too small, the sample will not be crushed. If it is too large, the pounding rod will directly contact the bottom wall of the pounding pot, and the material of the pounding rod or the pounding pot will be introduced as impurities. Therefore, the operation requires high skills and is difficult. Utility Model Content

[0003] The main purpose of the utility model is to provide a rare earth alloy sample preparation anti-oxidation device, which can reduce the oxidation of the sample during the crushing process and reduce the difficulty of operation.

[0004] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a rare earth alloy sampling anti-oxidation device is provided, including a pounding tank body, a pounding tank cover, and a pounding rod; the top of the pounding tank body is open, the pounding tank cover covers the top of the pounding tank body, and a through hole is provided in the middle of the pounding tank cover for the pounding rod to pass through.

[0005] As a further improvement, a tank flange is provided on the top of the pounding tank body, and the tank flange cooperates with the edge of the pounding tank cover.

[0006] As a further improvement, a silicone sealing ring is provided on the edge of the pounding tank cover.

[0007] As a further improvement, the tamping rod includes a tamping rod handle and a tamping head fixed to the tamping rod handle.

[0008] As a further improvement, the diameter of the tamping rod handle gradually decreases from the end toward the tamping head.

[0009] Further improvement, the surface of the pounding head facing the bottom wall of the pounding tank body is consistent with the curvature of the bottom wall surface of the pounding tank body, so as to increase the effective working area of ​​the pounding head for crushing

[0010] As a further improvement, the pounding tank cover is made of elastic material, and the outer surface is fixed by an elastic metal frame, the center of which is fixed by a rigid through sleeve; a rigid limiting frame is arranged below the elastic metal frame, and the rigid limiting frame is supported and fixed by the inner wall of the pounding tank body, and when the rigid through sleeve contacts the rigid limiting frame, the pounding head and the bottom wall of the pounding tank body have a set gap.

[0011] As a further improvement, the inner wall cross section of the rigid through sleeve is a hyperbolic shape.

[0012] As a further improvement, the tamping head and the tamping rod handle are detachably connected. The technical solution of the utility model has the following technical effects:

[0013] (1) A pounding tank cover is provided on the top of the pounding tank body, which basically blocks the flow of gas in the pounding tank body and external gas, reduces the amount of air that oxidizes the rare earth alloy sample in the pounding tank body, and reduces the oxidation of the sample during the pounding process.

[0014] (2) The elastic metal frame is supported by the tamping tank to crush the sample. When released, the elastic metal frame 2 drives the tamping rod to automatically return to the initial position, without the need to carefully apply force and drop it to the appropriate position, which reduces the difficulty of operation.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] Example 1

[0035] The first embodiment of the utility model provides a rare earth alloy sample preparation anti-oxidation device as follows Figure 1-4 As shown, it comprises a tamping tank body 1, a tamping tank cover 2, and a tamping rod 3. The top of the tamping tank body 1 is open. The tamping tank cover 2 is covered on the top of the tamping tank body 1. A through hole is provided in the middle of the tamping tank cover 2 for the tamping rod to pass through.

[0036] Among them, a tank support flange 11 is provided on the top of the pounding tank body, and the tank support flange 11 cooperates with the edge of the pounding tank cover 2, thereby basically blocking the flow of gas in the pounding tank body and external gas, and reducing the amount of air that oxidizes the rare earth alloy sample in the pounding tank body.

[0037] The material of the pounding tank cover can be made of transparent acrylic material, and a silicone sealing ring can be provided on the edge of the pounding tank cover to increase the sealing performance.

[0038] The tamping rod 3 includes a tamping rod handle 31 and a tamping head 32 fixed to the tamping rod handle 31. The surface of the tamping head 32 facing the bottom wall of the tamping tank body 1 is consistent with the curvature of the bottom wall of the tamping tank body 1. Specifically, the diameter of the tamping rod handle 31 gradually decreases from the end to the tamping head.

[0039] Example 2

[0040] The rare earth alloy sample preparation and anti-oxidation device provided in the second embodiment of the utility model is an improvement based on the first embodiment.

[0041] like Figure 5-7 As shown, the main improvements are as follows: the pounding tank cover 2 is changed to an elastic material, and the outer surface is fixed by an elastic metal frame 21, and the center of the elastic metal frame 21 is a rigid through sleeve 22; a rigid limit frame 4 is arranged below the elastic metal frame, and the rigid limit frame 4 is supported and fixed by the inner wall of the pounding tank body 1. A support flange can be arranged at this position with reference to Example 1. When the rigid through sleeve 22 contacts the rigid limit frame 4, the pounding head 32 and the bottom wall of the pounding tank body 1 have a set gap, and the size of the gap is equivalent to the particle size of the sample after pounding.

[0042] The tamping head 32 and the tamping rod handle 31 are detachably connected, for example, by a threaded connection.

[0043] Since the cross-section of the rigid through sleeve 22 is a hyperbolic shape with a minimum aperture in the middle, and the diameter of the tamping rod handle 31 gradually decreases from top to bottom, a suitable cross-section of the through sleeve 22 or a diameter of the tamping rod handle 31 is designed so that when the minimum aperture of the rigid through sleeve 22 matches the diameter of a position of the rod handle 31, the distance between the tamping head 32 and the bottom wall of the tamping tank body 1 is a distance suitable for tamping.

[0044] When in use, the sample to be crushed is placed in the pounding tank body 1, and then the pounding rod handle 31 passes through the rigid through sleeve 22 and the rigid limiting frame 4 in the center of the elastic metal frame 21 in turn, and then the pounding head 32 is installed on the pounding rod handle 31, and the whole is placed in the pounding tank body 1. The rigid limiting frame 4 and the elastic metal frame 2 are both supported by the pounding tank body 1. At this time, you can press down and turn the pounding rod handle 31 to crush the sample. When released, the elastic metal frame 2 drives the pounding rod to automatically return to the initial position, and there is no need to carefully apply force and fall in the appropriate position, which reduces the difficulty of operation. Due to the presence of the rigid limiting frame 4 and the cooperation between the pounding rod handle and the rigid through sleeve 22, even if a lot of force is used, the pounding head 32 will not contact the inner wall of the material tank body 1, further reducing the difficulty of operation.

[0045] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0046] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes.
