The cross section of the track 6 is a "U"-shaped structure. A conveyor belt 601 is provided in the track 6. The interior of the conveyor belt 601 is a hollow structure, wherein the wires connected to the reducer 13, the photoelectric switch 16 and the proximity switch 34 and the PLC controller, as well as the power cord, all pass through the conveyor belt 601, which protects the wires and the power supply and prevents the wires and the power cord from being entangled or worn when the transmission housing 8 moves.

When the proximity switch 34 detects the transmission housing 8, the signal is transmitted to the PLC controller, so that the PLC controller controls the reducer to stop, thereby preventing the steel wire-driven transmission housing 8 from sliding on the guide rod 4.

[0041] During use, after the steel wire is drawn, it continues to be transmitted forward through the upper pulley 32 and the lower pulley 33, so that it is located between the upper pressure plate 11 and the lower pressure plate 12, and at the same time is located below the limit wheel 1903 and the guide wheel 25. When the steel wire is drawn by the wire drawing machine, the meter of the wire drawing machine calculates the length of the transmitted steel wire.

The shaft of the reducer 13 drives the turntable 17 and the driving gear 35 to rotate. The driving gear 35 drives the driven gears 37 of the two rotating mechanisms to rotate, so that the driven gear 37 drives the transmission shaft 38 to rotate. The ends of the two transmission shafts 38 drive the inner ring of the second bearing 39 located on the mounting plate 7 to rotate. Under the action of the second bearing 39, the two transmission shafts 38 respectively drive the first eccentric wheel 21 and the second eccentric wheel 22 to rotate. The second eccentric wheel 22 drives the slide plate 10 of the upper pressure plate assembly to slide downward under the action of the fisheye bearing 23, and the slider 1001 slides downward on the slide rail 20, so that the slide plate 10 drives the upper pressure plate 12 to move downward; the first eccentric wheel 21 drives the slide plate 10 of the lower pressure plate assembly to slide upward under the action of the fisheye bearing 23, and the slider 1001 slides upward on the slide rail 20, so that the slide plate 10 drives the lower pressure plate 11 to move upward. When the first eccentric wheel 21 and the second eccentric wheel 22 rotate to half a circle, the upper pressure plate 12 and the lower pressure plate 11 are closed, thereby achieving the bending process of the steel wire. When the upper pressure plate 12 and the lower pressure plate 11 are closed to bend the steel wire, the steel wire being transmitted drives the transmission housing 8 to slide on the guide rod 4, that is, the guide block 14 slides to the right on the guide rod 4.

[0042] During the process of the transmission housing 8 sliding on the guide rod 4, the first eccentric wheel 21 and the second eccentric wheel 22 continue to rotate. While the first eccentric wheel 21 and the second eccentric wheel 22 rotate, they drive the upper pressure plate 12 to move upward and the lower pressure plate 11 to move downward. When the notch 18 on the turntable 17 rotates to the photoelectric switch 16, the photoelectric switch 16 transmits a signal to the PLC controller. The PLC controller controls the reducer 13 to stop working, and the upper pressure plate 12 and the lower pressure plate 11 return to their initial positions. The transmission housing 8 moves to the left under the action of the buffer spring 401, that is, the guide block 14 drives the transmission housing 8 to slide to the left on the guide rod 4, so that the transmission housing 8 returns to its initial position. The limit assembly limits the transmission housing 8. When the limit plate 801 contacts the rubber head 28, the transmission housing 8 stops moving to the left. After the wire is bent, it is transferred to the subsequent process for coating and packaging. When the wire production is completed, the staff can shorten the wire at the bend to ensure that the wire length wrapped around the spool is the same. The subsequent wire bending process is the same as above.
