[0034] like Figure 4 and Figure 5 As shown, the first cutting assembly 53 includes a first lifting drive mechanism 531 and a fishbone profiling cutting portion 532 , the driving end of the first lifting drive mechanism 531 is connected to the fishbone profiling cutting portion 532 , and the fishbone profiling cutting portion 532 is provided with a first positioning groove 001 .

[0035] like Figure 4 and Figure 5As shown, the second cutting assembly 54 includes a second lifting drive mechanism 541 and a second contour cutting portion 542 , the driving end of the second lifting drive mechanism 541 is connected to the second contour cutting portion 542 , and the second contour cutting portion 542 is provided with a second positioning groove 002 .

[0036] Specifically, the first lifting drive mechanism 531 is a first cylinder, which is fixedly connected to the top of the fixed frame 51, and the driving end of the first cylinder passes through the fixed frame 51 and is connected to the fishbone profiling cutting part 532, and the fishbone profiling cutting part 532 is provided with a plurality of fishbone-shaped groove cutting edges, and a first positioning groove 001 for accommodating the middle part of the wire 10 is provided between the fishbone-shaped groove cutting edges, and the first cylinder and the fishbone profiling cutting part 532 are located at one end of the fixed frame 51 close to the positioning mechanism 3. The second lifting drive mechanism 541 is a second cylinder, which is fixedly connected to the top of the fixed frame 51 and is located on one side of the first cylinder, and the second cylinder passes through the fixed frame 51 and is connected to the second profiling cutting part 542, and the second profiling cutting part 542 is provided with two rectangular cutting cutting edges, and a second positioning groove 002 for accommodating the middle part of the wire 10 is provided between the rectangular cutting edges.

The cutting base 52 is provided with a first profiling groove 521 and a second profiling groove 522 which are through-through from top to bottom. The first profiling groove 521 is adapted to the fishbone profiling cutting portion 532, and the second profiling groove 522 is adapted to the second profiling cutting portion 542.

[0037] The wire reel is placed on the unwinding mechanism 2, and the wire 10 of the wire reel passes through the positioning mechanism 3 and the transmission mechanism 4 in sequence. The transmission mechanism 4 clamps the wire 10, and then transmits the wire 10 to the first profiling groove 521 of the cutting base 52 of the cutting mechanism 5, and then the first cylinder of the first cutting component 53 drives the fishbone profiling cutting part 532 to cooperate with the first profiling groove 521 to cut the two sides of the wire 10 into symmetrical fishbone shapes. After the cutting is completed, the clamped wire 10 of the transmission mechanism 4 continues to be transmitted in the direction of the discharge end, and the wire 10 passes through the cutting base 52, and the first cutting component 53 cuts the wire 10, and the process is repeated in sequence. When the herringbone-shaped wire 10 is cut to a specified length, the second cylinder of the second cutting assembly 54 drives the second profiling cutting part 542 to cooperate with the second profiling groove 522 to cut off the wire 10 at both ends of the wire 10, so that the wire 10 is in the shape of a rib. After the cutting is completed, the transmission mechanism 4 clamps the wire 10 and continues to transmit it toward the discharge end.

The two clamping cylinders 43 are respectively located on both sides of the cutting mechanism 5. The clamping height of the clamping cylinders 43 is respectively adapted to the cutting base 52 and the feeding guide rail 34. The two clamping cylinders 43 can clamp the wire 10 at both ends of the cutting mechanism 5, and then drive the sliding plate 42 through the fifth cylinder to drive the two clamping cylinders 43 to clamp the wire 10 and move it in the direction of discharging, so as to convey the wire 10. Among them, the distance that the third cylinder drives the sliding plate 42 to move is relatively short, so that the conveying distance of the wire 10 by the clamping cylinders 43 is short.
