Control the corresponding second electromagnetic chuck to de-energize. Control the collar to move so that the insert clamps the wire and pulls the wire to move, so that it passes through the L-shaped groove and J-shaped groove in sequence.

[0022] 2.

[0056] Working principle of this embodiment two:

[0057] By inserting the take-up reel 9 into the corresponding plug 62, the positioning rod 94 is driven into the positioning hole on the slide rail 91 of the take-up reel 9 by the elastic force of the installation spring 68, thus completing the fixed installation of the I-shaped take-up reel 8 and the corresponding drive unit 7. Rotating the drive unit 7 causes the thin iron plate at the bottom of the I-shaped take-up reel 8 to be placed directly above the corresponding second electromagnetic chuck 92. Each group of second electromagnetic chucks 92 is connected in series and is initially energized. The corresponding second electromagnetic chuck 92 holds the corresponding I-shaped take-up reel 8 to prevent the turntable 5 from deviating in position during rotation, which would cause the conductor tube 27 to be unable to keep coaxial with the opposite L-shaped tube 11, affecting the subsequent wire lifting operation.

[0058] The servo motor 31 is controlled to start, driving the main gear 32 to rotate, which in turn drives the gear ring 30 to rotate. This causes each set of I-shaped take-up reels 8 on the turntable 5 to rotate synchronously at a certain angle. When the light-shielding plate 69 on one set of I-shaped take-up reels 8 rotates and blocks the infrared limit switch 70, the servo motor 31 is stopped. At this time, the corresponding L-shaped groove 11 is coaxially set with the wire tube 27. At the same time, the second electromagnetic coil 86 is energized to attract the second armature post 87, which drives the collar 40 to move. When the corresponding guide ball 43 moves on the inclined guide plate 46, it squeezes the guide ball 43 and drives the insertion rod 42 to gradually press against the wire 33. When it moves onto the first horizontal guide plate 45, the clamping of the wire 33 is completed.

[0059] As the collar 40 moves continuously along the first horizontal guide plate 45, it pulls the wire 33 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 sequence. When the abutment plate 88 presses against the pressure sensor 89, the pressure sensor 89 transmits a signal to the controller 90. The controller 90 controls the corresponding second electromagnetic chuck 92 to de-energize, releasing the restriction on the corresponding I-shaped take-up reel 8. At the same time, it controls each group of first electromagnetic chucks to de-energize synchronously. Under the elastic force of each first support spring 61, it drives the lifting ring 58 to rise, so that each group of insertion rings 59 inserts into the corresponding annular cavity 12, squeezing the corresponding annular elastic reset airbag 57, so that each group of elastic diaphragms 55 inflates and expands, squeezing the pressure groove on the wire 33, improving the stability of the connection between the wire 33 and the take-up reel 9. At the same time, the vertical rod 15 is squeezed to rise, so that the pressure rod 16 presses against the wire 33, further improving the stability of the connection between the wire 33 and the take-up reel 9.

[0060] After the automatic wire lifting of the wire 33 is completed, the second electromagnetic coil 86 is de-energized. Under the elastic restoring force of the compression spring 41, the compression spring 41 is driven to slide in the opposite direction, releasing the clamping limit on the wire 33. The first electromagnetic coil 85 is de-energized. Under the elastic force of the second support spring 83, the second friction wheel 81 is driven to rise and press against the bottom surface of the first friction wheel 72.

[0061] The lifting sleeve 26 has a slider inside. The reciprocating screw 24 is a type of three-dimensional cam pair, which consists of two threaded grooves with the same pitch but opposite directions of rotation, connected at both ends by transition curves. The rotation of the reciprocating screw 24 causes the side of the spiral groove to push the slider placed in the spiral groove to make axial reciprocating motion. This, along with the control start drive motor 74, drives the reciprocating screw 24 to rotate, causing the lifting sleeve 26 to move up and down. At the same time, the chain 79 drives the second friction wheel 81 and the first friction wheel 72 to rotate, thereby achieving uniform winding of the I-shaped take-up reel 8.

[0062] After the wire is reeled in, the electric push rod 49 is lowered, causing the cutter 53 to cut the wire 33. At the same time, the arc-shaped pressure plates 52 press grooves into the sides of the wire 33.

[0063] Example 3, please refer to Figures 1-17 This embodiment three is an improvement on embodiment two as follows: Specifically, a wire 33 is wound on the wire feeding frame; an L-shaped frame 93 is fixed to the side of the ear plate 22; a horizontal plate 34 is fixed to the side of the L-shaped frame 93; a first guide wheel 35 and a second guide wheel 36 are rotatably arranged on the side of the L-shaped frame 93; a third guide wheel 37 is rotatably arranged on the side of the horizontal plate 34; one end of the wire 33 passes through the wire drawing box, the annealing box, the first guide wheel 35, the second guide wheel 36 and the third guide wheel 37 in sequence and then passes through the wire guide tube 27.

[0064] Working principle of this embodiment three:

[0065] The annealing chamber alters the strength and rigidity of the wire 33. It can also change the fatigue strength, fatigue durability, corrosion resistance, and compressive strength of the wire 33.

[0066] A method of using an automatic reel-changing wire drawing machine includes the following steps:

[0067] T1. Attach each set of I-shaped take-up reels 8 to the corresponding drive unit 7. Rotate the drive unit 7 to make the thin iron plate rotate to be held directly above the corresponding second electromagnetic chuck 92, preventing the I-shaped take-up reels 8 from rotating freely during the rotation of the turntable 5.

[0068] T2. Control the turntable 5 to rotate at a certain angle so that the L-shaped groove 11 on a set of I-shaped take-up reels 8 is aligned with the conductor tube 27. Control the corresponding second electromagnetic chuck 92 to de-energize. Control the collar 40 to move 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 sequence. 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 take-up.

[0069] T3. Control the second friction wheel 81 to rise and press against the corresponding first friction wheel 72, control the start drive motor 74 to drive the first connecting shaft 75 to rotate, drive the reciprocating screw 24 to rotate, and cooperate with the chain 79 to drive the corresponding drive unit 7 to rotate, so as to complete the uniform winding of the corresponding I-shaped take-up reel 8.

[0070] T4. After the take-up is completed, control the cutter 53 to descend and cut the wire 33 placed in the semi-connecting tube 48. Control the turntable 5 to rotate at a specified angle and repeat the above operation to complete the automatic reel change after the take-up of the I-shaped take-up reel 8.
