[0048] Working principle of the second embodiment: By inserting the wire take-up drum 9 into the corresponding plug-in column 62, the positioning rod 94 is driven to be inserted into the positioning hole on the slide rail 91 on the wire take-up drum 9 under the elastic force of the installation spring 68, and the fixed installation of the I-shaped wire take-up drum 8 and the corresponding driving part 7 is completed. The driving part 7 is rotated so that the thin iron plate at the bottom of the I-shaped wire take-up drum 8 is placed directly above the corresponding second electromagnetic suction cup 92. Each group of second electromagnetic suction cups 92 is electrically connected in series, and the initial state is all energized. The corresponding second electromagnetic suction cup 92 sucks the corresponding I-shaped wire take-up drum 8 to prevent the turntable 5 from deviating from its position during rotation, resulting in the wire tube 27 being unable to maintain coaxiality with the relative L-shaped tube 11, affecting the subsequent wire drawing operation.

[0049] The servo motor 31 is controlled to start and drive the main gear 32 to rotate, and the gear ring 30 to rotate. Thus, each group of the zigzag take-up reels 8 on the turntable 5 is driven to rotate synchronously by a certain angle. When the light shielding plate 69 on a group of the zigzag take-up reels 8 rotates to block the infrared travel switch 70, the servo motor 31 is controlled to stop. At this time, the corresponding L-shaped groove 11 is coaxially arranged with the wire tube 27, and the second electromagnetic coil 86 is controlled to be energized to attract the second armature column 87, driving the ring 40 to move. When the corresponding guide ball 43 moves on the inclined guide plate 46, the guide ball 43 is squeezed to drive the plunger 42 to gradually press against the wire 33. When it moves to the first transverse guide plate 45, the wire 33 is clamped.

[0050] During the continuous movement of the ring 40 along the first transverse guide plate 45, the wire 33 is pulled to move synchronously, so that the end of the wire 33 passes through the L-shaped groove 11 and the J-shaped groove 13 in turn. When the plate 88 is pressed against the pressure sensor 89, the pressure sensor 89 transmits a signal to the controller 90. The controller 90 controls the corresponding second electromagnetic suction cup 92 to lose power, releases the restriction on the corresponding I-shaped wire take-up drum 8, and at the same time, controls each group of first electromagnetic suction cups to lose power synchronously. Under the elastic force of each first support spring 61, the lifting ring 58 is driven to rise, so that each group of plug-in rings 59 are inserted into the corresponding annular cavity 12, squeezing the corresponding annular elastic reset airbag 57, so that each group of elastic diaphragms 55 are inflated and expanded, squeezing the pressure groove on the wire 33, thereby improving the stability of the connection between the wire 33 and the wire take-up drum 9; at the same time, the vertical rod 15 is squeezed to rise, so that the pressure rod 16 is pressed against the wire 33, further improving the stability of the connection between the wire 33 and the wire take-up drum 9.

[0051] After the automatic drawing of the end of the wire 33 is completed, the second electromagnetic coil 86 is controlled to lose power, and the extrusion spring 41 is driven to slide in the opposite direction under the elastic restoring force of the extrusion spring 41, thereby releasing the clamping limit of the wire 33, and the first electromagnetic coil 85 is controlled to lose power, and the second friction wheel 81 is driven to rise and press against the bottom surface of the first friction wheel 72 under the elastic force of the second support spring 83.

Through the rotation of the reciprocating screw rod 24, the side of the spiral groove pushes the slider placed in the spiral groove to make axial reciprocating motion, and the control start drive motor 74 drives the reciprocating screw rod 24 to rotate, and drives the lifting sleeve 26 to reciprocate and lift. At the same time, the second friction wheel 81 is driven to rotate together with the first friction wheel 72 through the chain 79, thereby realizing the uniform winding of the Gongzi-shaped winding drum 8.

[0053] After the wire is taken up, the electric push rod 49 is controlled to descend, so that the cutter 53 cuts the wire 33 . At the same time, each group of arc-shaped pressing plates 52 presses the side surfaces of the wire 33 into a pressing groove.

[0054] For example 3, please refer to Figure 1-17 The third embodiment is improved as follows on the basis of the second embodiment.

[0055] Working principle of the third embodiment: The annealing box changes the strength and rigidity of the wire material 33 . The annealing box can also change the fatigue strength, fatigue durability, corrosion resistance and compressive strength of the wire material 33 .

[0056] A method for using an automatic disc-changing wire drawing machine comprises the following steps: T1. Clamp and install each group of the take-up drum 8 on the corresponding driving part 7, and rotate the driving part 7 to rotate the thin iron plate to the top of the corresponding second electromagnetic suction cup 92 to be sucked, so as to prevent the take-up drum 8 from rotating freely during the rotation of the turntable 5.

[0057] T2, control the turntable 5 to rotate a certain angle so that the L-shaped groove 11 on a group of I-shaped take-up reels 8 are aligned with the wire tube 27, control the corresponding second electromagnetic suction cup 92 to lose power, and control the movement of the ring 40 so that the insertion rod 42 clamps the wire 33 and pulls the wire 33 to move, so that it passes through the L-shaped groove 11 and the J-shaped groove 13 in turn, and then control the contact to clamp the wire 33, control the lifting member 21 to rise, and drive the pressure rod 16 to press against the end of the wire 33 to complete the automatic wire pulling.

[0058] T3, control the second friction wheel 81 to rise and press against the corresponding first friction wheel 72, control the start-up drive motor 74 to drive the first connecting shaft 75 to rotate, drive the reciprocating screw rod 24 to rotate, cooperate with the transmission of the chain 79 to drive the corresponding drive part 7 to rotate, and complete the uniform wire winding of the corresponding I-shaped wire winding drum 8.

[0059] T4. After the wire is taken up, the cutter 53 is controlled to descend to cut the wire 33 in the semi-connected tube 48, and the turntable 5 is controlled to rotate to a specified angle. The above operation is repeated to complete the automatic reel change after the wire is taken up by the I-shaped reel 8.
