Description

Technical Field

[0001] The present invention relates to the technical field of cable processing devices, and in particular to a wire stranding device and a wire stranding method for producing composite cables. Background Art

[0002] Wire stranding machine is a kind of mechanical equipment that can be widely used in twisting various soft / hard conductor wires, so that multiple single conductors are twisted into one strand to meet the process requirements of wires. 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 stranding devices are often customized and can only strand together a fixed number of conductors of a fixed type. Therefore, when processing cables of different types and radial sizes, it is necessary to equip multiple stranding devices of specific types, which greatly increases the production cost.

[0004] Therefore, a fully automatic stranding device for composite cable production proposed in the patent with publication number CN113223779A can lead out the conductor wire through the wire outlet wheel by setting the stranding drum and the wire outlet wheel, and twist the conductor wire by driving the stranding drum to rotate with the driving motor, and adjust the setting of the component, so that the position of the wire outlet block on the stranding drum can be adjusted, so that the number of conductor wires can be freely set according to the situation, thereby improving the applicability of the device. However, when the device increases or decreases the conductor wire and moves the position of the wire outlet block, it is necessary to cut the wire, remove it from the wire outlet block, adjust the position of the wire outlet block, and then go online to continue stranding. The operation steps are complicated and the production wire is discontinuous. Summary of the invention

[0005] The invention provides a wire stranding device and a wire stranding method for producing a composite cable, so as to solve the technical problem that the existing wire stranding device has complex operation for adjusting raw wires and needs to cut the wires, resulting in discontinuity of the cable.

[0006] The embodiments of the present invention are implemented by the following technical solutions:

[0007] A wire stranding device for composite cable production includes a protective cover, a wire stranding drum for stranding wires, a wire management device for arranging and shaping cables, and a plurality of wire threading holes for passing wires. It also includes through holes for the wires to radially pass through the threading holes and a perforated plate for opening and closing the through holes. The perforated plate is provided with a limiting hole for cooperating with the threading hole to limit the wire and an arc-shaped baffle for blocking the wire from sliding into the through hole.

[0008] Preferably, the orifice plate is further provided with a connecting rod for controlling the sliding of the orifice plate, and the winding drum is further provided with an expansion device for pushing the connecting rod and a sliding groove for limiting the connecting rod.

[0009] Preferably, the sliding groove is also provided with a spring member for contracting the connecting rod.

[0010] Preferably, the expansion device comprises a rotatably arranged expansion ring, a plurality of groups of expansion rods hinged to the expansion ring at intervals, and a limiting block for limiting the expansion rods so that they tilt up and push the connecting rod when the expansion ring rotates.

[0011] Preferably, the expansion rod comprises a front section and a rear section hinged to the expansion ring, and the front section covers the rear section of the adjacent front expansion rod.

[0012] Preferably, the wire drum is further provided with a control disk for controlling the rotation of the expansion ring, a rotating member for driving the wire drum to rotate, and a conical cylinder for combing and limiting the wire.

[0013] Preferably, the conical cylinder is also provided with a central hole for passing the central wire.

[0014] Preferably, two groups of arc-shaped limiting holes are provided at both ends of the orifice plate, and the orifice plate and the limiting holes divide the threading hole into two groups of smaller holes.

[0015] A composite cable stranding method, comprising the composite cable stranding device, comprises the following steps:

[0016] S1: Install the wires: Turn the control panel to slide the control hole plate outward until the through hole is opened. After the wires are installed, turn on the equipment to twist the wires;

[0017] S2: Adjust the wires: turn off the equipment, open the through holes by turning the control panel, distribute the adjusted wires to the threading holes at intervals, and then fix the wires through the orifice plate to continue twisting.

[0018] Preferably, in step S2, when taking out the wire, the wire can be fixed in the limiting hole, and the orifice plate can be pushed by rotating the control disk to drive the wire in the limiting hole to leave the twisting disk through the through hole; the wire can also be detached from the limiting hole, fixed in the threading hole, and the orifice plate can be radially contracted inward to take out the wire.

[0019] By adopting this technical solution, the wire can be taken out of the winding drum for adjustment without cutting the wire through the through hole. After adding or reducing the wire or adjusting the position of the wire, the wire can be fixed in the limit hole through the hole plate and the threading hole, which is convenient for adjusting the wire and will not affect the stability of the wire when the winding drum rotates.

[0020] The expansion device adopts an expansion ring to control the expansion rod to push the connecting rod, and further cooperates with the spring part to control the extension and retraction of the orifice plate. The front section of the expansion rod covers the rear section of the expansion rod on the adjacent side. A group of limit blocks can be used to control the tilting of one group of expansion rods, and at the same time, the tilting of the rear section can trigger the tilting of the front section of the adjacent expansion rod on the rear side, and the tilting is triggered in turn. A group of limit blocks can be used to realize the common control of all connecting rods, and the operation is simple.

[0021] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects:

[0022] 1. The present invention uses the through hole to take the wire out of the twisting drum for adjustment without shortening the wire, and fixes the wire in the limiting hole through the orifice plate and the threading hole, which facilitates the adjustment of the wire and does not affect the stability of the wire when the twisting drum rotates;

[0023] 2. The present invention realizes common control of all connecting rods through a group of limit blocks, and the operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS
