When the wire drawing is not needed, the external power switch is turned on, so that the electromagnetic sheet 44 is electrified to generate magnetism, the lock head 42 is sucked back to the original position, unlocking is completed, and finally, the upper guide roller 20 and the longitudinal guide roller 31 are reset, so that the next wire drawing can be performed.
It should be noted that: the manner in which the lock hole 26 can be aligned with the center of the communication opening is very simple in the prior art, because the size must be adjusted and calculated before the concrete production is put into production, which is well known to those skilled in the art, when the technical scheme of the application is known, only the distance by which the upper guide roller 20 drives the lock plate 25 to move upwards can be calculated according to the diameter of the conductor 3, so that the center of the lock hole 26 can be opposite to the communication opening between the Ji Zong chute 12 and the transverse sliding groove 13, and the position of the communication opening can be known.
Similarly, according to the radius of the conductor 3, the distance of the longitudinal guide roller 31 to drive the lock head 42 to move sideways can be calculated, so that the center of the lock head 42 is opposite to the communication opening between the Ji Zong chute 12 and the transverse chute 13, and the lock head 42 is convenient to clamp into the lock hole 26.
When it is necessary to wire a conductor 3 having a larger wire diameter, as in the wire drawing guide method for cable production, a conductor 3 having a diameter of 5mm is used as the wire drawing conductor 3, and a conductor 3 having a diameter of 8mm is used.
The locking plate 25 and the lock head 42 are displaced by a corresponding distance according to the diameter of the conductor 3, so that when the diameter of the conductor 3 is changed, the distance between the locking plate 25 and the lock head 42 is also changed, and the upper guide roller 20, the lower guide roller 21 and the longitudinal guide roller 31 can be effectively contacted and limited with the conductor 3 with the diameter of 8mm for effectively matching the locking plate 25 and the lock head 42.
The lock hole 26 is set to be square, triangle, pentagon in sequence from top to bottom, the lock heads 42 distributed from left to right on the left side slide block 40 are set to be square, triangle, pentagon in sequence, and the lock heads 42 distributed from right to left on the right side slide block 40 are set to be square, triangle, pentagon in sequence. Wherein, square locking plate 25 and tapered end 42 form joint cooperation and correspond 5mm, and triangle locking plate 25 and tapered end 42 form joint cooperation and correspond 8mm, pentagon locking plate 25 and tapered end 42 form joint cooperation and correspond 10mm.
In particular, when the electromagnetic sheet 44 is energized, the lock head 42 is magnetically attracted, the upper guide roller 20 performs the same operation as the above steps, and after the upper guide roller 20 presses down the 8mm conductor 3, the center of the triangular lock hole 26 is opposite to the communication port between the Ji Zong chute 12 and the lateral sliding chute 13.
Then, the longitudinal guide roller 31 performs the same operation as the above steps, when the longitudinal guide roller 31 is attached to the conductor 3 with the length of 8mm, the center of the triangular lock head 42 is opposite to the communication port between the Ji Zong chute 12 and the transverse sliding chute 13, at this time, the external power switch is turned off, so that the electromagnetic sheet 44 loses magnetism, and then the lock head 42 aligned with the center of the communication port is clamped into the lock hole 26 backwards under the action of the extension spring 43, finally the upper guide roller 20 and the longitudinal guide roller 31 cannot move, and the conductor 3 with the length of 8mm is limited.
After the wire drawing is finished, an external power switch is turned on, so that the electromagnetic sheet 44 is electrified to generate magnetism, the lock head 42 is sucked back to the original position, unlocking is finished, and finally, the upper guide roller 20 and the longitudinal guide roller 31 are reset, so that the next wire drawing can be performed.
