The sensing component controls the operation of the retractable power element 13a according to the trigger signal, and realizes automatic wire release and rewinding through the forward and reverse rotation of the retractable power element 13a. Moreover, according to the size of the pulling force, the sensing rod 44a triggers the sensing component to send different signals, and controls the speed of the retractable power element 13a, so that the wire feeding and rewinding process is more stable, and the tensioning and relaxation can be controlled freely and intelligently to achieve a stable tension, thereby ensuring the accuracy of the product.

[0081] After the wire passes through the guide mechanism 10 and enters the wire pulling mechanism 20, it is cleaned by the lubrication mechanism 30 and then enters the straightening mechanism 40 for automatic straightening. Initially, the wire passes through the first connecting portion 4211, the first guide block 426, the second guide block 427 and the third connecting portion 4213 in sequence. At this time, the wire is straight and concentric; Fig.11 As shown, when straightening is required, the fork positioning member 431 drives the first straightening bar 422 and the second straightening bar 423 to slide synchronously on the straightening roller 421, so that the first guide block 426 and the second guide block 427 are misaligned, and the wire is converted from a straight line concentric to a crankshaft concentric work, and under the high-speed rotation of the straightening roller 421, the friction between the first guide block 426 and the second guide block 427 and the wire is increased, and friction generates heat, so that the wire is quickly and automatically straightened; the misalignment is precisely adjusted by the intelligent control servo clutch, and the automatic straightening of the metal wire is completely and quickly realized in the high-speed asynchronous power transmission. The variable frequency wire feeding straightening speed can be based on the different toughness of the wire material, and the continuously variable speed is adopted. The straightening speed is automatically tracked to monitor the wear of the consumables, and automatic synchronous precision compensation is performed, which effectively improves the production efficiency, ensures high-quality product technology, reduces the waste of raw materials, and subverts the complex process and material waste of traditional operations.

[0082] After the straightening is completed, it is transmitted to the grinding mechanism 60 through the traction mechanism 50 to grind the surface of the wire. At the same time, the measuring device measures the rotation speed of the measuring wheel 54 and the length of the wire. When the measuring device measures that the metal wire has reached the preset length, the measuring device feeds back a cutoff signal to the controller. The controller controls the tracking power element 726 to start according to the response curve, and the rotating shaft 22 drives the push-pull cam 723, the cutter cam 724, the cutter power wheel 725 and the cross knife cam 728 to rotate synchronously. The push-pull cam 723 drives the push-pull slider 712 to slide vertically along the tracking guide rod 713, thereby forcing the first side plate 7211 to slide on the tracking support plate 711, and the bottom plate 7215 to slide on the workbench, so that the whole can move along the feeding direction of the metal wire. When the rotation speed of the transmission shaft 722 is synchronized with the rotation speed of the measuring device, the tracking The movement speed of the tracking frame 721 is synchronized with the movement speed of the metal wire and is in a relatively static state. At the same time, under the action of the cutter power wheel 725, the horizontal knife cam 728 quickly drives the pressing hammer 733 to press down, so that the second horizontal knife 822 is close to the first horizontal knife 821, so that the first horizontal knife 821 and the second horizontal knife 822 cooperate to press the wire to prevent the metal wire from being displaced; at the same time, the cutter cam 724 quickly drives the cutter hammer 732 to press down, so that the second vertical knife 832 is close to the first vertical knife 831, so that the first vertical knife 831 and the second vertical knife 832 cooperate to quickly cut off the metal wire, so that the cut cross-section of the metal wire is flat, smooth and without deformation; at this time, the cutting point of the cutter coincides with the cutting point measured by the measuring device; after the cutting is completed, the tracking power element 726 drives the transmission shaft 722 to move in the opposite direction, so that the whole is quickly reset. When cutting, the transmission shaft 722 is synchronized with the incoming speed of the metal wire, and the tracking frame 721 is relatively still with the incoming material, eliminating the pressure of the incoming material on the cutter and the reaction force related thereto. Through intelligent control tracking translation, servo synchronization and precise cutting, the cross section is flat and smooth without deformation, which can ensure the quality of the cut end surface and achieve precise length cutting. Finally, the cut wire is turned over to the receiving tray 92 through the material support 97.

[0084] In the fully automatic precision intelligent control straightening and cutting equipment for metal wires of the present invention, when the metal wire coil passes through the straightening mechanism 40 through the reel-up rack 100, the first straightening block 424 and the second straightening block 425 move and become dislocated, so that the metal wire is converted from being concentrically straight to being concentrically bent for straightening; when the preset length is reached, the tracking mechanism 70 receives the cutting signal of the measuring device and tracks the intersection point, and when the tracking mechanism 70 is synchronized with the rotation speed of the measuring device, the cutting mechanism 80 performs cutting, and the intelligent control tracking translation and servo synchronous precision cutting are used to ensure the quality of the cut end face and the cut length.
