[0002] Wire stranding machine is a kind of mechanical equipment that can be widely used in twisting various soft and hard conductor wires, so that multiple single conductors are twisted into one strand to meet the process requirements of wire materials. Wire stranding machine can be generally divided into single stranding machine, pair stranding machine, high-speed stranding machine, back-twisting machine, cage stranding machine, frame stranding machine, tubular stranding machine and disc stranding machine according to the stranding method.

[0003] Existing twisting machines usually twist all the wires together.

[0010] A method for twisting wires, comprising the following steps:

[0011] Step 1: Wire arrangement and perforation: Arrange several wires in parallel, pass the arranged wires through the wire holes, and pull out the end of one of the wires after passing through, pass it through the tapping guide needle and then merge with the rest of the wires. This wire is called a tapping wire;

[0012] Step 2: Reserving loose wires: The travel motor drives the second mobile frame to approach the first mobile frame, so that the ends of the arranged wires are placed in the first pneumatic clamp, the first pneumatic clamp clamps the ends of the wires, and then the first telescopic cylinder drives the first pneumatic clamp to move backward, dragging the arranged wires backward until the required length of the loose wires is obtained;

[0013] Step 3: First section of twisted wire: The second pneumatic clamp clamps the wire arrangement, and the rotating motor drives the rotating shaft to rotate, thereby driving the second pneumatic clamp to rotate, so that the wire arrangement rotates and hinges together, and at the same time the walking motor drives the second moving frame away from the first moving frame, gradually dragging more wires out of the twisted wire until the length of the first section of twisted wire is completed;

[0014] Step 4: Second section of twisted wire: The travel motor drives the first moving frame to approach the second moving frame, and the second pneumatic clamp clamps the starting end of the second section of untwisted wire, and at the same time clamps the two sections of the tapped wire on both sides of the tapped guide pin. At this time, the rotating motor drives the rotating shaft to rotate, thereby driving the second pneumatic clamp to rotate, and at the same time, the travel motor drives the first moving frame away from the second moving frame, gradually dragging out the remaining wire for twisting, until the length of the second section of twisted wire is completed;

[0016] The beneficial effects of the present invention are as follows: a tap guide pin is provided, and a wire segment which is not twisted together with the remaining wires is directly reserved in the middle section of the tap wire after the two sections of the wire are twisted. The wire segment can be cut along the middle to obtain two connector wires, which makes subsequent line connection more convenient and transmission more stable. BRIEF DESCRIPTION OF THE DRAWINGS
