Description

Technical Field

[0001] The utility model belongs to the technical field of metallographic specimen embedding, and more specifically, relates to a fixing device for embedding plate-shaped metallographic specimens. Background Art

[0002] When performing metallographic inspection on the cross-section of a thin plate specimen, due to its thin specification, it is extremely easy to skew during direct grinding, and it is not stable to hold by hand, and it is easy to scratch the sandpaper to cause flying samples, resulting in mechanical injuries to the sample grinding personnel. Therefore, when performing metallographic inspection on a thin plate specimen, the thin plate specimen must be embedded first. Since the cross-section of the thin plate specimen is thin and it is not easy to stand on the embedding platform of the embedding machine, it needs to be fixed with other devices before being embedded in the embedding machine. There are various existing embedding methods for thin plate specimens, but there will be gaps or incomplete filling between thin plate specimens and between the thin plate and the fixing object. The embedding material cannot be in full contact with the thin plate specimen, resulting in easy residue of dirt such as polishing paste during specimen grinding and easy residue of water stains during corrosion, and the sample preparation effect is poor; and the problem of pressure during hot embedding is not considered in the existing embedding methods. Usually, the pressure will cause the thin plate specimen to bend and deform. The above problems will seriously affect the embedding effect of the thin plate specimen and are not conducive to inspection and analysis. Summary of the Utility Model

[0003] The purpose of the utility model is to address the deficiencies existing in the prior art and provide a fixing device for embedding plate-shaped metallographic specimens, which solves the problem that when fixing a plate-shaped metallographic specimen through a fixing device in the prior art, there are gaps where the embedding material cannot be fully filled between the plate-shaped metallographic specimens or between the plate-shaped metallographic specimen and the fixing device, resulting in the embedding material not being able to be in full contact with the plate-shaped metallographic specimen.

[0005] A bracket, the bracket is in a gate shape, the open end of the bracket is used to be placed on the embedding platform of the embedding machine, and the inside of the bracket is used to accommodate at least one plate-shaped metallographic specimen;

[0006] At least two movable plates, one end of the movable plate is slidably connected to the closed end of the bracket, the other end of the movable plate is suspended inside the bracket, and the movable plate is used to clamp the plate-shaped metallographic specimen so that the plate-shaped metallographic specimen stands on the embedding platform.

[0007] Optionally, the bracket includes two vertical plates and a horizontal plate, the two vertical plates are connected to both ends of the horizontal plate, and a convex portion is provided at the inner side of at least one vertical plate near one end of the horizontal plate, and the convex portion is used to contact the plate-shaped metallographic specimen.

[0023] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0024] As Figure 1 shown, the present invention provides an inlay fixing device for a plate-shaped metallographic specimen, comprising:

[0025] A bracket 1, the bracket 1 is in a U shape, the open end of the bracket 1 is used to be placed on the inlay platform 10 of the inlay machine, and the inside of the bracket 1 is used to accommodate at least one plate-shaped metallographic specimen 2;

[0026] At least two movable plates 3, one end of the movable plate 3 is slidably connected to the closed end of the bracket 1, the other end of the movable plate 3 is suspended inside the bracket 1, and the movable plate 3 is used to clamp the plate-shaped metallographic specimen 2 so that the plate-shaped metallographic specimen 2 stands on the inlay platform 10.

[0027] Specifically, to solve the problem in the prior art that when fixing the plate-shaped metallographic specimen 2 through a fixing device, there is easily a gap where the embedding material cannot be fully filled between the plate-shaped metallographic specimens 2 or between the plate-shaped metallographic specimen 2 and the fixing device, resulting in the embedding material not being able to fully contact the plate-shaped metallographic specimen 2; the plate-shaped metallographic specimen 2 embedding and fixing device provided by the present utility model has a bracket 1 and at least two movable plates 3. The movable plates 3 can slide along the closed end of the bracket 1, and thus can clamp the plate-shaped metallographic specimen 2. By placing the bracket 1 on the embedding platform 10 and clamping the plate-shaped metallographic specimen 2 with the movable plates 3, the plate-shaped metallographic specimen 2 can be stood on the embedding platform 10. The lower end of the movable plate 3 is suspended inside the bracket 1, leaving a gap between it and the embedding platform 10 below. In this way, a relatively large space for the embedding material to enter is left on one side of the lower end of the clamped plate-shaped metallographic specimen 2, so that the embedding material can fully enter the side position of the plate-shaped metallographic specimen 2 and fully contact the plate-shaped metallographic specimen 2, ensuring the sample preparation effect.

[0028] Optionally, the bracket 1 includes two vertical plates 4 and a horizontal plate 5. The two vertical plates 4 are connected to both ends of the horizontal plate 5. A convex portion 6 is provided at the inner side of at least one vertical plate 4 near one end of the horizontal plate 5. The convex portion 6 is used to contact the plate-shaped metallographic specimen 2.

[0029] Specifically, the setting of the convex portion 6 enables a relatively large space to be formed between the vertical plate 4 and the lower end of the plate-shaped metallographic specimen 2 when the plate-shaped metallographic specimen 2 is close to this vertical plate 4 and is clamped by a movable plate 3, so that the embedding material can fully enter and fully contact the plate-shaped metallographic specimen 2.

[0030] In this embodiment, as Figure 1 shown, the two plate-shaped metallographic specimens 2 are respectively clamped by a vertical plate 4 with a convex portion 6 and a movable plate 3, and by two movable plates 3. In this way, whether between the plate-shaped metallographic specimen 2 and the vertical plate 4 or between the two plate-shaped metallographic specimens 2, there is enough space at the lower end for the embedding material to be fully filled.

[0031] In another embodiment, as Figure 2 shown, the two plate-shaped metallographic specimens 2 are clamped by three movable plates 3. There is enough space at the lower end between the two plate-shaped metallographic specimens 2 for the embedding material to be fully filled.

[0032] Optionally, a sliding groove 7 is provided in the middle of the horizontal plate 5. One end of the movable plate 3 is slidably arranged in the sliding groove 7.

[0033] Specifically, the upper end of the movable plate 3 realizes sliding cooperation with the horizontal plate 5 through connection with the sliding groove 7.

[0034] Optionally, the sliding groove 7 is a through groove.

[0035] Specifically, the through groove enables the sliding operation of the movable plate 3 to be performed from above the cross plate 5, facilitating the sliding of the movable plate 3.

[0036] Optionally, limiting grooves 8 are provided on both side walls of the sliding groove 7, and limiting protrusions 9 are provided on both sides of one end of the movable plate 3. Each limiting protrusion 9 is slidably disposed in a limiting groove 8.

[0037] Specifically, as Figure 3 shown, the sliding groove 7 accommodates the limiting protrusions 9 on both sides of the upper end of each movable plate 3 through the limiting grooves 8 on its both side walls, thereby enabling the movable plate 3 to be slidably connected to the inside of the bracket 1 in a suspended manner.

[0038] Optionally, the shape of the movable plate 3 is T-shaped, and the width of the other end of the movable plate 3 is smaller than the width of the plate-shaped metallographic specimen 2.

[0039] Specifically, as Figure 4 shown, the lower end of the movable plate 3 is narrower, occupying as little space on the side of the plate-shaped metallographic specimen 2 as possible when clamping the plate-shaped metallographic specimen 2, so that as much embedding material as possible enters the side of the plate-shaped metallographic specimen 2 and is in full contact with it.

[0040] Optionally, the movable plate 3 is a magnetic plate.

[0041] Specifically, the movable plate 3 is made of a magnetic plate, which can be attracted to the plate-shaped metallographic specimen 2, improving the stability of fixing the plate-shaped metallographic specimen 2.

[0042] In this embodiment, the movable plate 3 is made of a magnet material.

[0043] Optionally, the height of the cross plate 5 is greater than the height of the plate-shaped metallographic specimen 2.

[0044] Specifically, the height of the cross plate 5 is greater than the height of the plate-shaped metallographic specimen 2. When the plate-shaped metallographic specimen 2 is clamped upright inside the bracket 1, the upper end of the plate-shaped metallographic specimen 2 does not contact the cross plate 5, and the plate-shaped metallographic specimen 2 will not be bent and deformed during the hot embedding and pressurization process.

[0045] In summary, when the plate-shaped metallographic specimen 2 embedding and fixing device in this embodiment is used, taking the embedding of two plate-shaped metallographic specimens 2 as an example: Place the bracket 1 on the embedding platform 10 of the embedding machine, place the first plate-shaped metallographic specimen 2 inside the bracket 1 near the vertical plate 4 with the protrusion 6, adjust the position of the first movable plate 3 to clamp and fix the plate-shaped metallographic specimen 2, then place the second plate-shaped metallographic specimen 2, and continue to adjust the position of the second movable plate 3 to fix the second plate-shaped metallographic specimen 2. If the above operations are repeated, more plate-shaped metallographic specimens 2 can be placed in sequence; after that, add resin embedding powder for embedding. The parameters set for the metallographic embedding machine are heating temperature 180°C, time 12 min, water cooling; take out the embedded specimen after cooling to 80°C.

[0046] In another embodiment, place the bracket 1 on the embedding platform 10 of the embedding machine, move the first movable plate 3 to the set position, place the first plate-shaped metallographic specimen 2 on one side of the movable plate 3, adjust the position of the second movable plate 3 to clamp the first plate-shaped metallographic specimen 2, then place the second plate-shaped metallographic specimen 2, adjust the position of the third movable plate 3 to fix the second plate-shaped metallographic specimen 2. If the above operations are repeated, more plate-shaped metallographic specimens 2 can be placed in sequence; after that, add resin embedding powder for embedding.

[0047] The various embodiments of the present invention have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
