[0001] This utility model relates to the technical field of copper wire processing equipment, and in particular to a multi-strand stranding equipment for copper wire. Background Technology

[0002] Copper wire stranding machines are pre-processing equipment used in the production of standard parts and other metal products. Their purpose is to draw wires or bars produced by steel manufacturers and transported to standard parts and other metal product manufacturers, so that the diameter, roundness, internal metallographic structure, surface finish and straightness of the wires or bars meet the raw material processing requirements for the production of standard parts and other metal products.

[0003] Existing copper wire stranding machines have some problems in use. After the copper wire is stranded, it needs to be wound up. In the current technology, a winding spool is generally used to wind up the copper wire. However, there is a problem of tension imbalance during the winding process, which affects the winding effect. In addition, the winding spool needs to be replaced after winding. During the replacement process, the copper wire is prone to breakage, which is not conducive to subsequent processing.

[0004] Therefore, it is necessary to invent a multi-strand stranding device for copper wires to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-strand stranding device for copper wires to solve the problems mentioned in the background art.

One end of each movable arm is fixedly provided with a pressure wheel, and the two pressure wheels are respectively provided on both sides of the tension wheel.

[0009] Preferably, a positioning seat is provided above the support rod, and both ends of the positioning seat are rotatably provided with connecting arms via pins, and the bottom ends of the two connecting arms are respectively rotatably connected to one end of the two movable arms via pins.

[0010] Preferably, a threaded sleeve is fixedly provided in the middle of the positioning seat, and a positioning screw is provided inside the threaded sleeve through the thread.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model, by setting up a gantry, slide rail, slide block, tension wheel, fixed wheel and movable wheel, allows the copper wire to be wound up by the winding reel after passing through the fixed wheel, tension wheel and movable wheel in sequence after being twisted. During this process, the slide block is driven by the tension spring to move the tension wheel, so that the tension wheel and the copper wire are subjected to force to ensure that the copper wire is in a taut state, thereby ensuring the tension balance of the copper wire during the winding process. In addition, the slide block can slide along the inclined slide rail to realize the manual adjustment of the tension of the copper wire, thereby ensuring the tension balance of the copper wire during the winding process.

[0015] 2. This utility model, by setting a tension wheel and a pressure wheel, has two pressure wheels, one on each side of the tension wheel. During the replacement of the winding reel, by adjusting the position of the two pressure wheels, the copper wire is pressed tightly against the outside of the tension wheel, which can limit the copper wire and prevent it from losing traction and rebounding or breaking apart during the replacement of the winding reel. Furthermore, the copper wire, after being limited, is easy for the user to pull to the outside of the replaced winding reel, thus facilitating the continuous processing of the copper wire by the device.

The sliding hole and the sliding rod can ensure the stability of the sliding of the lead screw sleeve 28.

[0029] Working principle of this utility model:

[0030] In use, multiple strands of copper wire to be twisted are pulled through the inlet tube 3, and then the multiple strands of copper wire are repeatedly wound around the outside of the two winding reels 10. Then, guided by the guide wheel 6, they reach the outside of the fixed wheel 7. During this process, the twisting motor 25 drives the inlet tube 3 to rotate through the gear set, and the inlet tube 3 drives the winding reel 4 to rotate through the gear set. The multiple strands of copper wire are twisted in the process of passing through the inlet tube 3 and the winding reel 4. The twisted copper wire is guided by the fixed wheel 7, the tension wheel 8 and the movable wheel 9 to reach the outside of the winding reel 10. The winding motor 26 drives the winding reel 10 to rotate to complete the winding of the twisted copper wire. During this process, the winding reel 10 drives the reciprocating screw 27 to rotate through the gear set. The reciprocating screw 27 drives the screw sleeve 28 to slide horizontally back and forth. The screw sleeve 28 drives the movable wheel 9 to slide horizontally back and forth, so that the copper wire is evenly wound around the outside of the winding reel 10.

[0031] During the winding process of the copper wire by the reel 10, the copper wire passes through the tension wheel 8. At this time, the limit seat 13 is fixed to the outside of the slide rail 11 by the locking bolt 15. The limit seat 13 applies tension to the slide 12 and the tension wheel 8 through the tension spring 14. The tension wheel 8 applies tension to the copper wire, so that the copper wire is kept taut to ensure that the copper wire is wound evenly on the outside of the reel 10. During this process, the limit seat 13 can be released by rotating the locking bolt 15. By adjusting the position of the limit seat 13 on the outside of the slide rail 11, the position of the limit seat 13 and the slide 12 can be adjusted. When the copper wire is too tight or too loose, the position of the limit seat 13 and the slide 12 can be manually adjusted to adjust the tension of the copper wire.

[0032] When the winding reel 10 needs to be replaced after winding, stop the stranding motor 25 and the winding motor 26, and then rotate the positioning screw 23. Under the action of the threaded sleeve 22, the positioning screw 23 drives the positioning seat 20 to move upward. The positioning seat 20 drives one end of the movable arm 18 to move upward through the connecting arm 21. The movable arm 18 drives the pressure roller 19 to move upward, so that the two pressure rollers 19 move in the direction of the tension roller 8. At this time, the pressure roller 19 presses the copper wire tightly on the outside of the tension roller 8, which can achieve the clamping and fixing of the copper wire. At this time, the copper wire can be cut and the winding reel 10 can be replaced. During this process, the copper wire will not spring back or break apart.

[0033] It should be noted that in this embodiment, the inlet pipe 3, winding disc 4, conductor wheel 6 and other structures all adopt existing structures in the prior art. They constitute the head part of the copper wire stranding machine in the prior art, which can realize the stranding of copper wire. Since it is not related to this technical solution, it will not be described in detail here.

[0034] It should be further explained that the winding reel 10 is installed using a screw, nut and other structures. The screw is connected to the output shaft of the winding motor 26 via a transmission belt. The installation and driving of the winding reel 10 via the screw, nut and transmission belt is a mature existing technology that is used in various winding fields, so it will not be described in detail.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
