The bench drill body 1 and the worktable 2 of this design constitute the main body of the precious metal cutting machine, and a large number of related components are set in the main body of the precious metal cutting machine. Since they are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution. The suction fan 12 in this design is existing technology, and its model is: Jiuzhou Puhui 4-72-2.8A centrifugal fan. When in use, the air force of the suction fan 12 can be preset in advance. When the suction force of the suction fan is between [X1] and [X2] Pa (Pascal), it can effectively suck the precious metal debris on the worktable 2 into the collection box 6.

[0022] The main model of the precious metal cutting machine in this design is: Shengge Z516-1A multi-functional bench drill.

[0023] Preferably, a rectangular through groove is longitudinally formed on the surface of the top horizontal plate of the limiting cover 3, and the shape and size of the through groove are adapted to the drill bit on the surface of the bench drill body 1.

[0024] In practical use, the rectangular through slot opened longitudinally at the top of the limiting cover 3 facilitates the insertion of the drill bit on the surface of the bench drill body 1 into the inner wall of the limiting cover 3 to drill the precious metal raw material placed on the worktable 2.

[0025] Preferably, the opening end of the limiting cover 3 has a circular groove longitudinally provided, and the shape and size of the groove are adapted to the protrusions on both sides of the side plate 5. The limiting cover 3 has observation windows on the front and rear sides respectively.

[0026] In practical use, the baffle 4 is inserted longitudinally into the opening end of the limiting cover 3 to shield the precious metal raw materials on the workbench 2. At the same time, the observation window on the surface of the limiting cover 3 facilitates the observation of the processing of the precious metal raw materials on the workbench 2.

[0027] Preferably, the receiving box 6 has columnar protrusions on both sides, and the shape and size of the protrusions are adapted to the sliding grooves on the inner wall of the side plate 5.

[0028] In practical use, the protrusions on both sides of the receiving box 6 facilitate sliding and fixing its position within the side plate 5.

[0029] Preferably, the inner wall of the connecting pipe 7 is provided with a threaded groove, and the shape and size of the threaded groove are adapted to the threaded structure on the surface of the air outlet end of the suction pipe 9.

[0030] In practical use, the threaded groove on the inner wall of the connecting pipe 7 facilitates the connection between it and the suction pipe 9, and also makes it easy to disassemble and install the suction pipe 9 on one side of the receiving box 6.

[0033] Working principle: During precious metal raw material processing, the precious metal raw material to be cut is placed on the worktable 2. Then, the baffle 4 is inserted longitudinally into the opening end of the limiting cover 3 to shield the precious metal raw material on the worktable 2. At the same time, the rectangular through slot longitudinally opened on the top of the limiting cover 3 allows the drill bit on the surface of the bench drill body 1 to be inserted into the inner wall of the limiting cover 3 to drill the precious metal raw material placed on the worktable 2. During processing, the suction fan 12 is started, thereby using the preset air force of the suction fan 12 to force the connected suction pipe 9 and The receiving box 6 collects air through the groove on the workbench 2 that it abuts on, so that precious metal scraps falling on the workbench 2 are absorbed by the air and fall into the receiving box 6. At the same time, the filter screen assembly 8 embedded in the groove of the connecting pipe 7 at the front end of the receiving box 6 blocks and filters the absorbed precious metal scraps, preventing them from being sucked out through the suction pipe 9 and thus wasting precious metals. After processing, the receiving box 6, which is slidably connected to the side plate 5, can be pulled outward to facilitate the removal of the precious metals collected in the receiving box 6 for secondary processing.
