[0022] The stationary blade 1 and the movable blade 2 are both in the shape of long strips, and the stationary blade body cutouts 11 and the movable blade body cutouts 21 are respectively arranged on the long sides of the stationary blade 1 and the movable blade 2 .

[0023] The table top of the machine table 5 is provided with a recess, and the cutting motor 4 is sunk into the recess.

[0024] The output shaft of the cutting motor 4 is perpendicular to the table surface of the machine table 5. The transmission mechanism 3 includes a rotating rod 31, a connecting rod 32, a guide rod 33 and a guide sleeve 34. The two ends of the connecting rod 32 are hinged to one end of the rotating rod 31 and the guide rod 33 respectively.

The conveying motor 85 is installed on the frame 81 and the end of the output shaft is fixed to one end of the screw rod 83.

[0028] Working process of the present invention:

[0029] First, the cutting motor 4 drives the rotating rod 31 via its output shaft. The connecting rod 32 drives the guide rod 33 to move linearly along the guide sleeve 34, thereby driving the movable blade 2 to move linearly above the stationary blade 1 until the static blade 1's notches 11 and the movable blade 2's notches 21 overlap. Next, the feed motor 85 drives the screw rod 83, causing the nut 84 to move upward along the screw rod 83, thereby driving the support plate 7 and the respective drawing heads 6 thereon upward toward the respective steel wires to be processed. Subsequently, the main electromagnet 66 in each drawing head 6 is energized, using electromagnetic force to draw the steel wires through the overlapping static blade notches 11 and movable blade notches 21 and into the central channel 611. The feed motor 85 is then restarted, pulling the clamped steel wires downward to the desired position. The main electromagnet 66 in each drawing head 6 is then de-energized, and the torsion spring 63 uses its elastic force to force the free end of the screw rod 83 to clamp the steel wires. At this point, the auxiliary electromagnets 66 are energized and mutually attracted to each other, improving clamping stability. Next, the cutting motor 4 drives the rotating rod 31 again via the output shaft until the static blade 1's static blade cutouts 11 are offset from the dynamic blade 2's dynamic blade cutouts 21, achieving slitting of the individual steel wires. After the steel wires are cut, the flip motor 9 flips the support plate 7, and the auxiliary electromagnets 66 in the drawing heads 6 are energized again and mutually repel each other, forcing the free ends of the lead screws 83 to leave the central channel 611 and release the cut steel wire segments, allowing the steel wire segments to fall freely due to gravity.

[0030] The present invention arranges the movable blade and the stationary blade in parallel one above the other and arranges a plurality of movable blade body cuts and stationary blade body cuts on the same side of the two blades, so that the cutting motor can use the transmission mechanism to drive the movable blade to move back and forth above the stationary blade during operation, so that the movable blade body cuts and the stationary blade body cuts are staggered or overlapped, thereby realizing multiple synchronous cutting of steel wires, and the cutting frequency is higher than that of a pneumatic cylinder or a hydraulic cylinder; by arranging a rotating rod, a connecting rod, a guide rod and a guide sleeve to form a transmission mechanism, the rotary motion can be converted into a linear motion, so that the movable blade is prompted to repeat the motion along the required route, and the speed of the motion can be adjusted in real time according to the rotation speed of the cutting motor; by arranging The cylinder, elastic clamping mechanism and main electromagnet together constitute the drawing head, which can use the electromagnetic force of the main electromagnet to suck the steel wire into the cylinder, and then use the elastic force of the torsion spring to clamp the steel wire. Finally, the conveyor and the support plate drive the movement of each drawing head to achieve the purpose of clamping and drawing the free end of the steel wire. After the slitting of the steel wire is completed, the flip motor can be used to flip the each drawing head, and the electromagnetic force of the auxiliary electromagnet is used to offset the elastic force of the torsion spring, so as to use gravity to complete the self-release of the steel wire segment. By adding a rubber sleeve with an anti-slip texture at the free end of each clamping finger, the friction is effectively increased, thereby enhancing the clamping stability of the steel wire.
