[0042] Optionally, as shown in the figure, the gas conveying mechanism 4 further comprises a guide gasket 471, and a mounting groove with a lower end opening is arranged at the lower end of the main shaft 43, the mounting groove is coaxially distributed with the fourth drop hole 41, and the guide gasket 471 is arranged in the mounting groove. Figure 2

[0043] In the embodiment, when the copper pipe enters the fourth drop hole 41, the guide gasket 471 can guide the copper pipe. Secondly, by arranging the mounting groove at the lower end of the main shaft 43, and inserting the guide gasket 471 into the mounting groove through the lower end opening of the mounting groove, the guide gasket 471 can be quickly assembled.

[0044] Optionally, as shown in the figure, the gas conveying mechanism 4 further comprises a water stop plug 472, and the guide gasket 471 and the water stop plug 472 are sequentially arranged in the mounting groove, and the water stop plug 472 is located below the guide gasket 471. Figure 2

[0045] In the embodiment, by arranging the water stop plug 472, the fourth drop hole 41 can be blocked by the water stop plug 472, which can prevent water from seeping into the copper pipe clamping mechanism 5, and improve the water tightness. By sequentially inserting the guide gasket 471 and the water stop plug 472 into the mounting groove, the water stop plug 472 can be quickly assembled.

[0046] Optionally, as shown in the figure, the copper pipe blanking mechanism 1 comprises a barrel 12 and a hopper 13, and the electric spark perforating machine frame comprises a fixed support 6, the fixed support 6 is arranged in a “Fang” shape structure, an installation hole penetrating through the upper end of the fixed support 6 in the vertical direction is arranged at the upper end of the fixed support 6, the hopper 13 is inserted into the lower part of the installation hole, and the barrel 12 is inserted into the upper part of the installation hole. Figures 2 to 6

[0047] A material groove 121 is arranged in the barrel 12, a plurality of copper pipes are arranged in the material groove 121, a guide groove 131 is arranged in the hopper 13, the diameter of the guide groove 131 gradually decreases from top to bottom, the first drop hole 11 is arranged at the lower end of the hopper 13, and the material groove 121, the guide groove 131 and the first drop hole 11 are sequentially communicated.

[0048] ​​​A gap 62 is arranged between the lower end of the barrel 12 and the upper end of the funnel 13, an air inlet hole 61 is arranged on the fixed support 6, and an annular air groove 122 is arranged on the lower end of the barrel 12; the air inlet hole 61 is in communication with the annular air groove 122, the gap 62 and the guide groove 131 in sequence.

Secondly, the material groove 121, the guide groove 131 and the first drop hole 11 are coaxially distributed. In addition, the material groove 121 is open at the upper end.

[0051] In the embodiment, a plurality of copper pipes are placed in the material groove 121 of the barrel 12. Due to the communication between the lower end of the material groove 121 and the guide groove 131, the lower ends of the plurality of copper pipes fall into the guide groove 131 under the influence of gravity. By supplying air into the air inlet hole 61, the airflow enters the air inlet hole 61 and enters the guide groove 131 through the annular air groove 122 and the gap 62; the airflow flows along the inner wall of the guide groove 131 from the upper end of the guide groove 131 to the lower end of the guide groove 131, and due to the small diameter of the first drop hole 11, the airflow will generate an upward pushing force in the guide groove 131 after being gathered, thereby pushing the plurality of copper pipes to jump in the material groove 121 inside the barrel 12. Therefore, by intermittently supplying air into the air inlet hole 61, the plurality of copper pipes in the material groove 121 inside the barrel 12 can be made to jump, and one of the copper pipes can fall into the first drop hole 11, so that it can fall from the first drop hole 11. A sliding groove is arranged on the lower end of the fixed support 6 and penetrates the lower end of the fixed support 6 in the vertical direction, and the lower end of the top core 24 is slidingly connected to the sliding groove, thereby facilitating the movement of the top core 24.
