[0042] Working principle and advantages of the present invention: When the wire stranding device for wires and cables is used to process wire strands, the working process is as follows:

[0043] Step 1: If Figure 1 , Figure 3 and Figure 4 As shown, the winding drums 25 where the single wires to be twisted are located are sequentially installed on the turntable 7. During installation, the spring 1 31 is compressed by the tube shaft 28 so that the second inner groove 45 on the tube shaft 28 can be plugged into the corresponding multi-faceted rod 2 32. This arrangement facilitates the installation and removal of the winding drum 25, thereby facilitating the replacement of the winding drum 25. After the installation of each winding drum 25, the ends of each single wire are sequentially passed through the cone cylinder 10, the rolling cylinder 12, the wire feeding wheel 13 and the wire feeding wheel 2 15;

[0044] Step 2: Start the motor and power it on. Figure 5As shown, at the same time, the electromagnet 35 is energized to generate electromagnetic suction force, so that the iron plate 36 approaches the electromagnet 35 and fits and fixes thereto, so that the iron plate 36 stretches the spring 2 38 to obtain a restoring force, and the iron plate 36 drives the stop gear plate 3 away from the gear 1 4 through the slide rod 37, so that the gear 1 4 is in contact with the locked state. After the motor is started, the pulley assembly 44 cooperates with the wire feeding wheel 1 13 and the wire feeding wheel 2 15 to rotate in opposite directions at the same speed, so that the wire feeding wheel 1 13 and the wire feeding wheel 2 15 apply a traction tension to the twisted wires. The traction tension makes each single wire drive the corresponding winding drum 25 to rotate, so as to automatically release the wire, and it can also be used The traction force is used to automatically keep each single wire in a taut state, thereby maintaining the quality of the wire twisting. When the wire twisting is completed or needs to be stopped midway, the motor is powered off. At this time, the wire feeding wheel 13 and the wire feeding wheel 2 15 stop applying traction force to the twisted wires, and the electromagnet 35 is powered off at the same time, and no electromagnetic attraction is applied to the iron plate 36. Under the restoring force of the spring 2 38, the iron plate 36 drives the stop tooth plate 3 to move up and reset through the slide rod 37, so that the stop tooth plate 3 is meshed and connected with the gear 1 4, realizing automatic stop locking of the gear 1 4 and the turntable 7, preventing the turntable 7 from continuing to rotate and release the wire due to inertia, thereby preventing each single wire from loosening;

[0045] Step 3: If Figure 1 , Figure 3 and Figure 4 As shown, the winding drum 25 rotates while driving the tube shaft 28 to rotate through the polygonal rod 1 30, so that the tube shaft 28 drives the shaft rod 3 33 to rotate through the polygonal rod 2 32, so that the shaft rod 3 33 drives the shaft rod 1 6 to rotate through the bevel gear set 27, and then the shaft rod 1 6 drives the turntable 7 to rotate under the action of the gear 2 5 and the gear ring 46, so that each single wire can be twisted while the wire is automatically released. The structure is simple and the operation is efficient. The speeds required for pulling, releasing and twisting are automatically adapted to be consistent, and there is no need for multiple adjustments and corrections, which saves time and effort, and realizes continuous and high-quality twisting processing of wires, greatly improving work efficiency and product quality. Figure 2 As shown, when the twisted wire passes through the rolling cylinder 12, the rolling wheel 43 rolls the twisted wire under the action of the spring 41, thereby eliminating the residual stress between the single wires after twisting, thereby improving the flexibility of the twisted wire and further improving the quality of the wire;

[0046] Step 4: While the wire feeding wheel 2 15 rotates, the piston plate 20 is driven to move up and down in the pump barrel 19 through the connecting rod 16 and the push-pull rod 18. Since the conduction direction of the one-way valve 1 22 points to the inside of the pump barrel 19, and the conduction direction of the one-way valve 24 points to the oil nozzle 11, when the piston plate 20 moves up, a suction force is generated in the pump barrel 19, and the suction force draws the lubricating oil in the oil storage tank 17 into the pump barrel 19 through the liquid pipe 1 21. When the piston plate 20 moves down, a compression force is generated in the pump barrel 19, and the compression force transports the lubricating oil in the pump barrel 19 to the oil nozzle 11 through the liquid pipe 2 23, and then the oil nozzle 11 sprays it onto the surface of each single wire in the cone 10, thereby achieving the lubricating oil coating on the surface of each single wire while pulling the twisted wires, thereby protecting each single wire when twisting.

A wire stranding device for electric wires and cables according to claim 5, characterized in that: A one-way valve (22) and a two-way valve (24) are fixed and connected to the lower end of the side wall of the pump barrel (19); the one-way valve (22) is connected to the oil storage tank (17) through a one-way pipe (21), and the conducting direction of the one-way valve (22) points to the inside of the pump barrel (19); the one-way valve (24) is connected to the oil injection nozzle (11) fixed on the cone barrel (10) through a two-way pipe (23), and the conducting direction of the one-way valve (24) points to the oil injection nozzle (11).

7. A wire stranding method for a wire stranding device for electric wires and cables according to any one of claims 1 to 6, characterized in that: include: Step 1: Install each winding drum (25) on the wire-releasing and twisting mechanism; Step 2: Start the traction mechanism to pull the twisted single wires and use the traction force of each single wire to drive the wire-releasing and twisting mechanism to automatically release the wires; Step 3: The wire-paying and twisting mechanism automatically pays off the wires and twists the individual wires at the same time, and the twisted wires are subjected to the traction force of the traction mechanism and then use the friction force to drive the rolling assembly to roll and release the pressure; Step 4: The traction mechanism drives the lubricating oil coating mechanism to spray lubricating oil on the surface of each single wire while traction is being performed on the twisted single wires.
