Description

TECHNICAL FIELD

[0001] The utility model belongs to the metallographic pattern preparation technical field especially relates to a device for thin plate metallographic sample preparation. BACKGROUND

[0002] Thin plate metallographic sample preparation mainly includes the following steps: sampling, inlaying, polishing, polishing and corrosion. When inlaying the thin plate metallographic sample, the cut thin plate metallographic sample raw material is embedded in the mold with resin, and is prepared into a regular standard metallographic sample, which is convenient for polishing and microscopic observation. The inlaying method includes hot inlaying and cold inlaying, and the appropriate inlaying method and resin are selected according to the material properties.

[0003] When cold inlaying the metallographic sample raw material, the cut metallographic sample raw material is first placed on the lower mold, then the upper mold is placed on the lower mold, and then the prepared resin is poured into the mold for solidification. However, when inlaying multiple metal samples, pouring resin into multiple molds one by one is too time-consuming, and it is difficult to control the pouring speed of the resin, which can easily cause air in the resin to be poured too fast, thereby affecting the observation of the sample. In view of the above defects: Therefore, we propose a device for thin plate metallographic sample preparation. UTILITY MODEL CONTENTS

[0030] As shown in Figures 1-4 The device for preparing a thin plate metallographic sample of the present application comprises a metallographic sample inlay mold, a mold limiting structure and an embedded reagent injection structure.

[0031] The metallographic sample inlay mold comprises an upper mold cylinder 10 and a lower mold plate 11 threadedly connected to the inner wall of the upper mold cylinder 10. The lower mold plate 11 is screwed into the upper mold cylinder 10, then the cut metallographic sample raw material is placed on the lower mold plate 11, and then the resin liquid can be injected into the upper mold cylinder 10. After the resin liquid solidifies, the inlaying can be completed.

[0032] The mold limiting structure comprises a bottom plate 20 and six limiting cylinders 21 fixedly installed in a circumferential array on the upper surface of the bottom plate 20. The inner wall of the limiting cylinder 21 allows the upper mold cylinder 10 to be inserted. After the lower mold plate 11 and the upper mold cylinder 10 are assembled into one body, the upper mold cylinder 10 can be placed into the limiting cylinder 21, so that the metallographic sample inlay mold can be limited and fixed.

[0033] The embedded reagent injection structure comprises a support cylinder 30 fixedly installed on the upper surface of the bottom plate 20, an embedded reagent placing assembly arranged on the surface of the support cylinder 30, and an embedded reagent pushing assembly arranged on the upper end of the support cylinder 30.

After the resin liquid is poured into the embedding reagent storage cylinder 41, the embedding reagent storage cylinder 41 can be placed into the fixing groove, at this time, the limiting ring 44 is located at the upper end of the fixing disc 40, so that the embedding reagent storage cylinder 41 can be prevented from falling off, and the spring safety valve can prevent the resin liquid from flowing out along the flow guide pipe 42 in the initial state.
