Description

Technical Field

[0001] The utility model relates to the technical field of graphite product processing, in particular to a drilling machine for deep hole processing of high-purity graphite products. Background Art

[0002] Graphite plates have good electrical conductivity, high temperature resistance, acid and alkali corrosion resistance, and easy processing. Therefore, they are widely used in metallurgy, chemical industry, electrochemistry and other industries. Graphite plates include high-purity graphite plates, electrode graphite plates and flexible graphite plates. Graphite powder is soft and black-gray; it feels greasy and can contaminate paper. Under oxygen-free conditions, its melting point is above 3000℃, making it one of the most temperature-resistant minerals. The chemical properties of graphite powder are relatively stable at room temperature, and it is insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and electrical conductivity, and can be used as refractory materials, conductive materials, and wear-resistant lubricating materials.

[0003] However, in the prior art, when using a traditional drilling machine for deep hole processing of graphite products, the thickness of the graphite products to be processed deep holes are different. If the graphite cannot be positioned according to the thickness of the graphite products, the position of the graphite will shift during the deep hole processing, affecting the effect of the deep hole processing. In addition, if the position of the graphite product to be drilled is fixed, the drill bit will encounter obstacles during the deep hole processing, making it impossible for the drill bit to completely penetrate the graphite product, further affecting the effect of the deep hole processing.

[0023] Working principle:

[0024] When in use, the workbench 1 is fixed on the ground, and the graphite product is first clamped and fixed by the positioning device 3. The operator slowly pushes the graphite product that needs deep hole processing into the glass box 31 from the entrance of the glass box 31. The upper and lower surfaces of the graphite product are respectively fitted with the upper inclined plate 361 and the lower inclined plate 341, and the upper inclined plate 361 and the lower inclined plate 341 cooperate to form an eight-shaped shape, which is convenient for the graphite product to be better pushed into the glass box 31. As the graphite product is slowly pushed in, the upper surface of the graphite product squeezes the upper inclined plate 361 and the moving frame 36 to move upward, and the moving frame 36 drives the piston rod in the piston member 35 to move upward, so that the compression spring 351 undergoes elastic deformation until the graphite product is pushed and placed on the placement frame 34;

[0026] The graphite particles and dust generated by the deep hole processing are collected by the dust removal device 4, and the larger graphite particles fall directly into the dust box 42 along the conical bucket 41. The dust remaining on the upper surface of the graphite product after the deep hole processing is blown into the dust box 42 through the blowing hood 48 by the operation of the exhaust fan 46. The air containing graphite powder is sucked into the dust suction pipe 43 through the air inlet pipe 45. When the air flow passes through the filter 44, the graphite powder is filtered and removed by the filter 44. The clean air is then blown through the air outlet pipe 47 to the dust remaining on the upper surface of the graphite product after the deep hole processing. The blown air flow is dispersed by the dispersion sheet 481, and the flow rate of the air from the air inlet pipe 45 to the air outlet pipe 47 is accelerated by the exhaust fan 46, so that the upper and lower surfaces of the graphite product are dusted at the same time, thereby avoiding graphite dust from polluting the air, recycling the graphite, and saving resources.
