The bending motor can drive the rotating table to rotate on the supporting table to provide a power basis for the continuous bending of the copper wire. The rotating ring is set on the rotating table through the limit block. The adjusting screw in the rotating ring cooperates with the movable block. Since the external threads on both sides of the adjusting screw surface rotate in opposite directions, there are matching internal thread holes in the movable block. By controlling the rotation of the adjusting screw, the movable block can be moved relative to or away from each other, thereby changing the distance between the two bending wheels, which can meet the clamping requirements of copper wires of different specifications.

The servo electric cylinder in the positioning block drives the clamping block, which can effectively clamp and position copper wires of different specifications. For copper wires with smaller diameters, the micro-electric cylinder drives the clamping plate to further enhance the positioning effect and ensure the stability of the copper wire during the bending process. The electric heating plate in the arc groove of the right positioning block clamping block can heat the bending area of ​​the copper wire, reduce the hardness and rebound of the copper wire, and improve the bending quality. The rotating table and the bending wheel cooperate with the continuous feeding of the guide wheel, and the copper wire can be continuously bent according to the preset parameters. The discharging conveyor belt in the discharging rack of the discharging unit can smoothly deliver the bent copper wire.

[0036] Embodiment 4: Specifically, the present embodiment discloses a working method of a copper wire bending device for a plug-in strip suitable for plug-in strip processing, comprising the following steps: Step 1, the copper wire to be bent is sent from the cleaning sponge 9 inside the first fixing member 6 into the mounting frame 5, the cleaning sponge 9 cleans the surface of the copper wire to remove impurities, and then the copper wire passes through a plurality of first straightening wheels 10 staggered up and down on the right side of the mounting frame 5, these first straightening wheels 10 perform preliminary straightening on the copper wire when passing through, so that the copper wire becomes straighter in the up and down direction; the copper wire after preliminary straightening continues to move to the left, and passes through a plurality of second straightening wheels 11 staggered front and back on the left side of the mounting frame 5, the second straightening wheels 11 further straighten the copper wire, so that it also achieves a good straightness in the front and back direction, completing the automatic surface cleaning and straightening treatment of the copper wire, laying the foundation for the subsequent bending process; Step 2, the straightened copper wire is sent out from the cleaning sponge 9 inside the second fixing member 7. When the copper wire is sent out to a preset length, the two linear slide rails 12 on the left side of the second fixing member 7 drive the sliding block 13 on one side to slide relatively, so that the copper wire cutters 14 on one side of the two sliding blocks 13 approach the surface of the copper wire, and finally the copper wire is cut by the two copper wire cutters 14 to achieve fixed-length feeding, ensuring that the copper wire lengths at the corresponding positions of each strip are consistent, which is convenient for subsequent standardized operations such as assembly; Step 3, the cut copper wire is transported to the side of the bending wheel 22 under the action of the guide wheel 16. The four guide wheels 16 rotatably arranged on both sides of the top of the mounting block 15 are covered with rubber sleeves on their circumferences, which can not only guide the copper wire during transportation, but also protect the surface of the copper wire from damage. According to the specifications of the copper wire, the distance between the two bending wheels 22 is adjusted by controlling the adjusting motor 23. The output shaft of the adjusting motor 23 drives the driving gear 24 to rotate, and the driving gear 24 meshes with the outer circumference of the rotating ring 25 to rotate the rotating ring 25. Since the two ends of the adjusting screw 20 are inserted into the rotating ring 25, the rotating ring 25 drives the adjusting screw 20 to rotate when it rotates. Because the external threads on both sides of the surface of the adjusting screw 20 rotate in opposite directions, and there are matching internal thread holes in the movable block 21, when the adjusting screw 20 rotates, the two movable blocks 21 will move relative to or away from each other, thereby changing the distance between the two bending wheels 22 to meet the clamping requirements of copper wires of different specifications; Step 4, when the copper wire is transported to a suitable position, the two bending wheels 22 clamp the surface of the copper wire, and the bending grooves on the peripheral surface of the bending wheel 22 can better position the copper wire. At this time, the bending motor 26 at the bottom of the fixed frame 1 is started, and its output shaft drives the rotating table 18 to rotate on the top of the support table 17, so as to automatically bend the copper wire at the position clamped by the two bending wheels 22. As the guide wheel 16 continuously transports the copper wire to one side of the bending wheel 22, the rotating table 18 cooperates with the two bending wheels 22 to continuously bend the copper wire according to the preset bending processing parameters; Step 5. When the copper wire is bent, the positions of the connecting block 29 and the positioning block 30 are adjusted by the electric slide 1 28 and the electric slide 2 31 according to the bending position of the copper wire. The electric slide 1 28 on the left side controls the left connecting block 29 to slide up and down, and adjusts the height of the left positioning block 30; the electric slide 1 28 on the right side can slide up and down to adjust the height of the right positioning block 30 under the action of the electric slide 2 31, and can also move left and right to further adjust the position of the right positioning block 30, so as to accurately locate different bending areas of the copper wire; the positioning block 30 on the right side The bending area of ​​the copper wire is coated, and the electric heating sheet inside the clamping block 33 is used to heat the bending area of ​​the copper wire to reduce the hardness and springback of the copper wire. When the front end of the copper wire is bent, the positioning block 30 on the left is coated on the surface of the copper wire, and the driving ends of the two servo electric cylinders 32 control the two clamping blocks 33 to clamp and position the surface of the copper wire. For copper wires with smaller diameters, the driving ends of the micro-electric cylinders 34 inside the two clamping blocks 33 can also be used to control the clamping plates 35 to further clamp and position the surface of the copper wire to ensure the stability of the copper wire during the bending process. Step 6. The copper wire after the bending process falls on the discharge conveyor belt 37 inside the discharge rack 36. The discharge conveyor belt 37 sends the bent copper wire out. At the same time, the workpiece camera 38 on the top of the discharge rack 36 captures the image of the copper wire after the bending process and sends the captured image to the processor. The processor compares the captured image of the bent copper wire of the extension cable with the preset image of the bent copper wire of the extension cable. According to the comparison result, the bending operation parameters of the bending unit 3 are automatically adjusted to realize automatic updating and optimization of the bending parameters, thereby ensuring the bending processing quality of the extension cable copper wire to the greatest extent.
