Referring to fig. 7 to 10, in the present embodiment, preferably, in step S2, a reaming needle 2 is provided, which includes a needle shaft 21, and a reaming portion 22 is provided at a lower end of the needle shaft 21, and is capable of extending into a preformed through hole on the punching flat portion 11 and performing extrusion reaming on an inner wall of the preformed through hole to form a spinneret hole 12. Preferably, the outer diameter of the hole enlargement part 22 is configured to be 0.01mm to 0.04mm larger than the hole diameter of the prepared through hole in the punching flat part 11. Preferably, the preset diameter size of the spinneret orifice is configured to be 0.2mm to 0.5 mm. The outer diameter of the hole enlarging portion 22 is matched with the preset diameter of the spinneret hole.
Referring to fig. 7 to 10, in the present embodiment, it is preferable that the predetermined diameter size of the spinneret hole is set to 0.3mm, the outer diameter size of the hole enlarging portion 22 of the hole enlarging needle 2 is set to 0.3mm, and the hole diameter size of the preformed through hole formed in the hole punching flat portion 11 is set to 0.28 mm.
Referring to fig. 7 to 10, in the present embodiment, preferably, the hole enlarging acting portion 22 includes a first circular truncated cone 221, a first ball table 222, a cylinder 223, a second ball table 224, and a second circular truncated cone 225, and the first circular truncated cone 221, the first ball table 222, the cylinder 223, the second ball table 224, and the second circular truncated cone 225 are connected in a smooth transition manner from top to bottom in sequence to form a waist drum-shaped structure with a thick middle and thin two ends. In this embodiment, reaming effect portion 22 is the waist drum-shaped structure, and like this, when reaming effect portion 22 deepened and extrudes the reaming in the prefabricated through-hole, the part on reaming effect portion 22's cylinder 223 will not with pore wall direct contact, can reduce the friction of reaming effect portion 22 and pore wall, need not to utilize high strength pressure just can make reaming needle's reaming effect portion 22 extrude the reaming to the prefabricated through-hole inner wall on the spinneret body 1.
Referring to fig. 7 to 10, in the embodiment, the diameter of the lower bottom surface of the second circular truncated cone 225 is slightly smaller than that of the preformed through hole, and the diameter of the cylinder 223 is slightly larger than the aperture of the preformed through hole. Preferably, the diameter of the cylinder 223 is 0.2mm to 0.5mm, and the height of the cylinder 223 is 0.01mm to 0.1 mm.

In the process of extending the reaming action part 22 into the prefabricated through hole for extrusion reaming, the taper of the second truncated cone 225 at the lower end of the reaming action part 22 needs to be reasonably configured, and it can be understood that when the taper of the second truncated cone 225 is larger, the second truncated cone 225 is more blunt, the inclination angle of the side surface of the second truncated cone 225 relative to the vertical direction is larger, and the change of the outer diameter is fast; on the other hand, as the taper of the second round table 225 is smaller, the side surface of the second round table 225 becomes smaller with respect to the inclination angle in the vertical direction, and the change in the outer diameter is gradual. Therefore, in the extrusion reaming process, if the taper of the second circular truncated cone 225 is too large, the inner wall of the preformed through hole will be rapidly extruded and expanded by the reaming action part 22, which may cause damage to the hole wall and thus reduce the service life of the spinneret, and if the taper of the second circular truncated cone 225 is too small, although the process of extruding and expanding the inner wall of the preformed through hole will be more gradual and can reduce the possibility of damage to the hole wall, the processing speed will be greatly affected, which leads to a longer processing cycle, therefore, in this embodiment, the taper of the second circular truncated cone 225 is preferably configured to be 2:5, which can reduce the possibility of damage to the hole wall in the extrusion reaming process as much as possible on the premise of ensuring the extrusion reaming efficiency, and thus can further improve the service life of the spinneret.
