[0081] Metal wire conveying and cutting process:

[0082] The linear metal wire 9 is located between the synchronous roller 23 and the alignment roller 24, and multiple synchronous rollers 23 are synchronized with the first motor 22, and the alignment roller 24 is a driven wheel. The rotating synchronous roller 23 drives the metal wire 9 to move forward. During the movement, the contact sensor 28 monitors the presence of the metal wire 9 and transmits the signal to the controller. The controller drives the adjustment base 25 to float up and down by controlling the first adjustment cylinder 27 to increase or decrease the distance between the synchronous roller 23 and the opposing roller, thereby achieving the purpose of straightening the metal wire 9. The metal wire 9 passing through the alignment roller 24 and the synchronous roller 23 is straightened.

[0083] When the straightened wire is introduced into the metal wire 9 limit block 35 through the synchronous roller 23, and the encoder synchronously monitors the travel length of the wire and transmits the signal to the controller, but travels the preset length, the controller controls the second motor 32 to rotate, and the second motor 32 drives the adapter plate 33 to rotate. The eccentric adapter plate 33 drives the cutter 37 to slide horizontally through the first hinge rod 34 and the cutting slider 36 in turn. The horizontally sliding cutter 37 and one end of the metal wire 9 limit block 35 form a cutting structure to complete the cutting of the set length of wire.

[0084] Bending process of the first bending component:

[0085] One end of the linear metal wire 9 passes through the metal wire 9 limit block 35 and contacts the upper surface of the slope plate 47, and is guided to the upper surface of the first substrate 41 through the slope plate 47. Then, one end of the metal wire 9 passes through the second limit block 48, the transition block and the first limit block 44 in sequence. At this time, the outer periphery of the metal wire 9 is located in the first limit slot and the second limit slot, and the metal wire 9 is located on one side of the first lever 424. After the cutter 37 cuts the metal wire 9, the controller controls the second cylinder 49 to retract, and the transition limit block 410 sinks below the first substrate 41, and the transition limit block 410 and the second limit block 48 do not interfere with the metal wire 9. To bend the wire 9, after the second cylinder 49 completes its contraction, the controller controls the third motor 45 to rotate. The transmission gear of the third motor 45 drives the first shaft sleeve 423 to rotate through the two first gears 421, and the two first gears 421 are engaged with each other, so the two first shaft sleeves 423 rotate in opposite directions. The first lever 424 is eccentrically mounted on the first shaft sleeve 423. The rotating first shaft sleeve 423 drives the first lever 424 to slide along an arc trajectory. The outer periphery of the first lever 424 abuts against the outer periphery of the shaft metal wire 9 to complete the bending of the metal wire 9. The two first levers 424 work together to bend the cut metal wire 9 into a U-shaped structure.

[0086] Bending process of the second bending component:

[0087] During implementation, the second bending assembly 5 bends the metal wire 9 at different positions and in different bending directions. The U-shaped metal wire 9 bent by the first bending assembly 4 is transported from the first bending assembly 4 to the second bending assembly 5 through the conveying device 8, wherein the third limit block 53 is used to limit the relative position of the metal wire 9, and then the controller controls the third cylinder 55 telescopic rod to drive the first pressing plate 56 to press the end of the U-shaped metal wire 9, and the controller controls the fourth motor 57 to drive the screw to rotate, and the first slide 59 is limited by the third bending roller 52 and the packaging slider 511, so that the first slide 59 is only It can slide axially, and the rotating screw drives the first slide 59 to slide axially. The packaging slide 510 moves along the axial direction of the screw, and the long hole on the packaging slide 510 is set obliquely. The third bending roller 52 is affected by the slider and only slides horizontally, and does not move up and down. The two opposite and horizontally sliding third bending rollers 52 bend the two side wall ends of the U-shaped metal wire 9. After the second bending component 5 is bent, it is transferred to the third bending component 6 by the conveying component. The third bending roller 52 of the third bending component 6 is located in the middle of the side wall of the U-shaped metal wire 9, and bends the two side walls from outside to inside respectively.

[0088] The bending process of metal wire by vertical bending assembly:

[0089] The metal wire 9 bent by the third bending roller 52 is transferred to the receiving plate 72 through the conveying device 8. The fourth limit block 73 on the receiving plate 72 positions the metal wire 9. Then the controller controls the fourth cylinder 76 to retract the positioning slide 74. The positioning slide 74 limits the metal wire 9 between the positioning slide 74 and the fourth limit block 73. Then the controller controls the fifth motor 710 to rotate in the opposite direction for a set number of circles. The fifth motor 710 drives the second lead screw 711 to rotate. The lower pressure plate 77 moves downward through the lead screw module principle, and the upper side wall of the lower pressure plate 77 presses the first part 91 of the metal wire 9 down by an angle. , then controls the fifth motor 710 to reset, controls the fifth cylinder 712 to push the pressing block 713 to press the first part 91 to one side of the pad, so that the first part 91 is fully formed, and then the controller controls the fifth motor 710 to rotate forward, and the lower side wall of the lower pressing plate 77 moves upward to bend the second part 92 of the metal wire 9, and the upper pressing plate 714 moves upward to bend the third part 93 of the metal wire 9. At this time, the bending of the metal wire 9 is completed, and the controller controls the fifth motor 710 to reset. At the same time, the controller controls the fourth cylinder 76 to stretch the positioning slide bar 74, and then the conveying device 8 transports the bent metal wire 9.

[0090] The transmission process of the conveyor device:

[0091] The conveying device 8 is equipped with three first grabbing components 83 and one second grabbing component 84. The spacing between the two first grabbing components 83 and the spacing between the first grabbing component 83 and the second grabbing component 84 are consistent with the spacing between the first bending component 4, the second bending component 5, the third bending component 6 and the vertical bending component 7. The controller drives the linear slide 810 to slide axially by controlling the sixth motor 87 to rotate, and the linear slide 810 drives the cross plate 82 to slide horizontally, and the displacement of the horizontal sliding is the same as the spacing, so that the first grabbing component 83 initially positioned on the first bending component 4 is located above the second bending component 5 after moving, and so on, and the second grabbing component 84 is initially positioned It is placed above the vertical bending component 7 and is located above the external shelf after displacement. The controller controls the sixth cylinder 81 to extend and retract, which can drive the first finger cylinder 833 and the second finger cylinder 843 to approach the metal wire 9 or away from the upper end of the bracket 1 to complete the process of taking and placing the metal wire 9. A rotary drive 844 is also added to the second grabbing component 84. The rotary drive 844 is used to drive the metal wire 9 to rotate through the second finger cylinder 843 to facilitate the selection of the unloading angle on the external shelf. Similarly, a seventh cylinder 845 is set on the second finger cylinder 843. The seventh cylinder 845 drives the metal wire 9 to move axially through the second finger cylinder 843 to facilitate the selection of the unloading position on the external shelf.
