Embodiment 1

[0047] see figure 1 As shown, the present invention provides an inlay tool for metallographic sample preparation, which can fix the wire to be inlaid perpendicular to the bottom surface of the inlay mold in a clamping manner, thereby reducing the occurrence of false images.

[0048] Specifically, the tooling structure includes: a main body 1 with an upper opening and a lower opening, and a crimping pin 2 .

[0049] From the appearance structure, such as figure 1 It can be seen that the main body 1 includes two partial structures, an upper part and a lower part. Wherein, the upper part is a cylindrical structure; the lower part is a kiln-shaped structure, and at least three inverted U-shaped slots 3 are provided at symmetrical positions on the side walls of the lower part. The function of the crimping pin 2 here is that when the crimping pin 2 moves from the upper opening to the inside of the main body 1 , at least two wires 4 to be inlaid can be pressed against the upper inn...

Embodiment 2

[0064] Based on the aforementioned embodiment 1, in order to solve the technical problem that the crimping pin is easy to fall into the inside of the main body during the inlay operation and it is difficult to take it out, the crimping pin 2 has a pin head 5 to prevent it from slipping.

[0065] Figure 4 with Figure 5 The front view and cross-sectional view of a metallographic sample preparation mosaic tool provided by the embodiment of the present invention are respectively shown. It can be seen that the crimping pin 2 has a pin head 5 that is larger than the inner diameter of the opening on the main body of the tooling, so that the crimping pin 2 is When reaching the deepest position, the pin head 5 is stuck to the upper opening of the main body 1, so that it will not fall into the inside of the main body 1.

[0066] It should be noted here that the diameter of the pin head 5 is not only larger than the inner diameter of the upper opening of the main body 1, but also smal...

Embodiment 3

[0068] Based on the foregoing embodiments, in order to further improve the fixing effect of the wire material 4 to be inlaid, as Image 6 As shown, in a practicable manner, the crimping pin 2 has several crimping grooves 6 at axially symmetrical positions of the pin body. Figure 7 shows the use of Image 6 The crimping pin 2 shown is the front view of the tooling for fastening the wire 4 to be inlaid (filling the shaded part). It can be seen that based on the crimping groove 6 of the crimping pin 2, the wire 4 to be inlaid can be inserted into the crimping The groove 6 effectively ensures the verticality of the wire 4 to be inlaid when it is put into the main body 1 .

[0069] Preferably, the positions of the crimping grooves 6 on the crimping pins 2 are symmetrical, so as to ensure uniform stress on each wire 4 to be inlaid when fastened.

[0070] It should be noted that, in the embodiment of the present invention, the groove depth of the crimping groove 6 is less than or ...

Abstract

The invention discloses a metallographic sample preparation inlaying tool, and relates to the technical field of metallographic inlaying. The tool comprises a main body with an upper opening and a lower opening, and a wire pressing pin; the main body comprises an upper part and a lower part; the upper part is cylindrical; the lower part is kiln-shaped, and at least three inverted U-shaped groovesare formed in the symmetrical positions of the side wall; and the wire pressing pin moves towards the interior of the main body from the upper opening so that the at least two to-be-embedded wires arestressed to be attached to the inner wall of the upper part of the main body. The invention also discloses a metallographic sample preparation inlaying method using the tool for inlaying. The perpendicularity parameters of various soft wires in metallographic sample preparation inlaying can be effectively improved, the problem that the soft wires are prone to diameter distortion in the inlaying process is solved, and metallographic observation artifacts are remarkably reduced.

Description

technical field [0001] The invention relates to the field of metallographic inlay, in particular to a metallographic sample preparation inlay tool and an inlay method. Background technique [0002] Metallographic sample preparation (that is, metallographic sample preparation) is an important part of metallographic research, which aims to analyze the quality of the material through the inspection and observation of metal material samples (generally, the cross-section of the sample is taken). Because the quality of metal materials often directly affects product performance and safety, and has a great impact on the working life of products, metallographic sample preparation is of great value in material application and process research. [0003] In metallographic sample preparation, mosaic is an indispensable key link. In the mosaic process of the prior art, the cut and sampled wire samples are often placed vertically into the mosaic mold, and then the solidified material is p...
