Embodiment Construction

[0026] The present invention will be further explained in conjunction with the accompanying drawings.

[0027] In practical applications, the processed left pliers arm 1 and right pliers arm 2 are connected into one body with a connecting shaft pin 3 to realize that the left pliers arm 1 and the right pliers arm 2 can rotate around the shaft pin 3 to open and close. The length of the positioning slot 21 on the right pliers arm 2 should be appropriate to prevent the positioning pin 11 from interfering with the pliers arm when the pliers arm is opened and closed and cannot be opened or closed. The positioning pin 11 is welded to the left clamp arm 1 at the middle position of the positioning groove 21 on the right clamp arm 2. Thus, the main part of the clamp body of the sample sampling clamp of the present invention is completed.

[0028] The left mold 5 and the right mold 6 design the cavity 62 according to the requirements of the sample. The multiple cavities 62 are connected in t...

Abstract

A pair of metal melt sample collection tongs comprises a hand-held clamp tongs assembly, one set of sample molds comprising a left mold (5) and a right mold (6) and a sampling position indicating rod assembly, wherein the hand-held clamp tongs assembly comprises a left tong arm (1) and a right tong arm (2), the two tong arms are connected by a shaft pin (3), so as to form the working tongs capable of manually opening, closing and clamping; the two molds are respectively connected with the two tong arms by bolts and open and close along with the tong arms, and after the two molds are closed, a complete mold is formed; the sampling position indicating rod assembly comprises an indicating rod (7), a guide seat (8) and a fixation bolt (9); the guide seat (8) is fixed on the mold, and the indicating rod (7) passes through the guide hole of the guide seat (8) and is fixed by the fixation bolt (9). By adopting the structure, various metal melt samples can be conveniently and quickly prepared, and the preparation efficiency and quality of the metal samples can be effectively improved.

Description

Technical field [0001] The invention belongs to the technical field of metal processing. technical background [0002] Metal casting production is one of the most extensive process methods in the field of material processing. In the process of casting process production and experiment, in order to inspect the quality of metal melt, it is often necessary to collect melt samples on site for metallographic analysis, mechanical property analysis, electron microscopy analysis, etc., on the basis of inspection and analysis. It is possible to prepare a good metal melt for metal forming. [0003] At present, in the process of production and experiment, the commonly used methods for sampling high temperature metal melt mainly include: [0004] (1) There is an independent sample mold: Use a small crucible to take a small amount of melt, and then pour the melt into the sample mold. In actual operation, this method often results in too much or too little melt casting due to improper operati...
