DETAILED DESCRIPTION

[0031] The present invention Figure 1 As shown in FIG. 6 , a flat wire motor copper wire arc bending machine and a bending method thereof include a conveying mechanism 10 for clamping and driving the copper wire in an “inverted U” shape to move, a bending mechanism 20 for bending the copper wire, and a control unit for controlling the bending mechanism 20; wherein:

[0032] The bending mechanism 20 is located beside the conveying mechanism 10; the distance between the two end points of the upper part of the copper wire is S, the S of the initial copper wire before bending is equal to the initial value S0, and the S of the copper wire after bending is equal to the preset value S1; with the end point on the right side of the upper part of the copper wire as the tangent point, a tangent line L tangent to the copper wire is made to the left, and the angle between L and S is α, the α of the initial copper wire before bending is equal to the initial value α0, and the α of the copper wire after bending is equal to the preset value α1; with the end point on the left side of the upper part of the copper wire as the tangent point, a tangent line M tangent to the copper wire is made to the right, and the angle between M and S is β, the β of the initial copper wire before bending is equal to the initial value β0, and the β of the copper wire after bending is equal to The preset value is β1; the control unit controls the bending mechanism 20 to adjust S from S0 to S1, adjust α from α0 to α1, and adjust β from β0 to β1 to complete the bending of the copper wire; the bending mechanism 20 includes a first torsion drive component 23 for adjusting the α value, a distance adjustment drive component 24 for adjusting the S value, and a second torsion drive component 25 for cooperating with the first torsion drive component 23 to adjust the β value, and the distance adjustment drive component 24 is installed at the output end of the first torsion drive component 23; the second torsion drive component 25 is installed at the output end of the distance adjustment drive component 24.

[0033] The control unit can be a PLC controller, which automatically realizes the conveying, bending and bending degree control of the copper wire by adopting the conveying mechanism 10, the bending mechanism 20 and the control unit, and completes the precise bending of the copper wire by adjusting S from S0 to S1, adjusting α from α0 to α1 and adjusting β from β0 to β1. The upper part 30 of the copper wire before bending is placed horizontally, and the upper part 31 of the copper wire after bending is in a bent shape, which improves the bending accuracy of the copper wire, simplifies the procedural steps of the copper wire bending, facilitates operation, and reduces the defective rate.

[0034] The bending mechanism 20 also includes a support frame 21, a clamping assembly 22 for clamping the right side wall of the copper wire, and a clamping cylinder 26 for clamping the left side wall of the copper wire. The above-mentioned first torsion drive assembly 23 is longitudinally installed on the upper side of the support frame 21; the clamping cylinder 26 is installed on the output end of the above-mentioned second torsion drive assembly 25; the clamping assembly 22 is installed on the lower side of the support frame 21, and the clamping cylinder 26 is movably corresponding to the clamping end of the clamping assembly 22.

[0035] The clamping component 22 clamps and clamps the upper end of the right side wall of the copper wire to limit the position of the copper wire; the first torsion drive component 23 drives the distance adjustment drive component 24, the second torsion drive component 25 and the clamping cylinder 26 to twist a certain angle together; the distance adjustment drive component 24 drives the second torsion drive component 25 and the clamping cylinder 26 to move together, the second torsion drive component 25 drives the clamping cylinder 26 to twist, and the clamping cylinder 26 clamps the upper end of the left side wall of the copper wire to twist and move, thereby bending the upper part of the copper wire; the overall structure is compact, occupies a small area, and is easy to operate.

[0036] The first torsion drive assembly 23 drives the clamping cylinder 26 to twist and thereby adjust the value of α, the distance adjustment drive assembly 24 drives the clamping cylinder 26 to move and thereby adjust the value of S, and the first torsion drive assembly 23 and the second torsion drive assembly 25 cooperate with each other to drive the clamping cylinder 26 to twist and thereby adjust the value of β.

[0037] By adjusting S, α and β, the upper part of the copper wire can be precisely bent. The procedure is simple, the operation is convenient, the overall structure is compact and the practicability is strong.

[0038] The torsion centers of the first torsion drive assembly 23 and the second torsion drive assembly 25 driving the clamping cylinder 26 to twist are both consistent with the center of the clamping cylinder 26 .

[0039] The consistency of the torsion orientation of the clamping cylinder 26 driven by the first torsion drive assembly 23 and the second torsion drive assembly 25 is ensured, and the position deviation and misalignment caused by the inconsistency between the torsion center and the center of the clamping cylinder 26 are prevented, thereby improving the torsion accuracy.

[0040] The control unit controls the operation of the bending mechanism 20, and the bending mechanism 20 feeds back the values ​​of S, α and β during operation to the control unit. The control unit monitors the change of S starting from the initial value S0, the change of α starting from the initial value α0, and the change of β starting from the initial value β0.

[0041] The control unit controls the operation of the bending mechanism 20 by monitoring the values ​​of S, α and β, thereby improving the accuracy and meeting the copper wire bending angle requirements.

[0042] The control unit monitors the values ​​of S, α and β. When S is equal to a preset value S1, α is equal to a preset value α1 and β is equal to a preset value β1, the control unit controls the bending mechanism 20 to stop running.

[0043] When S is equal to the preset value S1, α is equal to the preset value α1, and β is equal to the preset value β1, it indicates that the bending degree of the copper wire has met the requirements and the copper wire has reached the bending standard. The control unit controls the bending mechanism 20 to stop running. In actual operation, the clamping cylinder 26 can also continue to bend the upper part of the copper wire so that the bending degree of the copper wire slightly exceeds the copper wire bending standard. The clamping cylinder 26 then resets the copper wire to the bending standard position. This can reduce the rebound degree of the copper wire and improve accuracy.

[0045] The conveying mechanism 10 conveys the copper wire to the side of the limit block 223, and the upper end of the right side wall of the copper wire abuts against the limit block 223. The longitudinal driving cylinder 221 drives the clamping block 222 to move toward the limit block 223, and the clamping block 222 and the limit block 223 abut against each other. The upper end of the right side wall of the copper wire is fastened between the clamping block 222 and the limit block 223. The clamping assembly 22 is used to limit the upper end of the right side wall of the copper wire, which is convenient for the bending operation on the upper part of the copper wire and prevents the position of the copper wire from shifting.

[0046] The conveying mechanism 10 includes a support 11, a rotary drive motor 12 and a transmission belt 13. The rotary drive motor 12 is vertically installed on the support 11.

[0047] The rotary drive motor 12 drives the transmission belt 13 to move cyclically along the support 11 , and the movement of the transmission belt 13 drives the plurality of fixture seats 14 to move synchronously, thereby improving the working efficiency.

[0048] The first torsion drive assembly 23 includes a first torsion drive motor 231 and a first torsion disk 232, and the first torsion disk 232 is installed on the shaft end of the first torsion drive motor 231; the distance adjustment drive assembly 24 includes a distance adjustment drive device 241 and a slide 242, the distance adjustment drive device 241 is connected to the lower side of the torsion disk, and the slide 242 is installed on the output end of the distance adjustment drive device 241; the second torsion drive assembly 25 includes a second torsion drive motor 251 and a second torsion disk 252, the second torsion drive motor 251 is connected to the lower side of the slide 242, and the second torsion disk 252 is installed on the shaft end of the second torsion drive motor 251.

[0050] The bending method of the flat wire motor copper wire arc bending machine comprises the following steps:

[0051] First, the conveying mechanism 10 clamps the middle of the right side wall of the copper wire in an "inverted U" shape and conveys it to the side of the bending mechanism 20; the distance between the two end points of the upper part of the copper wire is S; a tangent line L tangent to the copper wire is made to the left with the end point on the right side of the upper part of the copper wire as the tangent point, and the angle between L and S is α; a tangent line M tangent to the copper wire is made to the right with the end point on the left side of the upper part of the copper wire as the tangent point, and the angle between M and S is β;

[0052] Second, the clamping assembly 22 of the bending mechanism 20 clamps the upper end of the right side wall of the copper wire;

[0053] Third, the clamping cylinder 26 clamps the upper end of the left wall of the copper wire. Driven by the first torsion drive assembly 23, the distance adjustment drive assembly 24 and the second torsion drive assembly 25, the clamping cylinder 26 moves and twists toward the clamping block 222 of the clamping assembly 22 to bend the upper end of the copper wire.

[0054] Fourth, the first torsion drive assembly 23 drives the clamping cylinder 26 to twist and adjust the value of α, the distance adjustment drive assembly 24 drives the clamping cylinder 26 to move along the placement direction of the first torsion disk 232 to adjust the value of S, and the first torsion drive assembly 23 and the second torsion drive assembly 25 cooperate with each other to drive the clamping cylinder 26 to twist and adjust the value of β;
