Abstract
A preparation method for composite cable is provided. The said composite cable comprises a plurality of cables with oversheath in paralleled arrangement. The method includes steps as follows: material selection, sheathing adhesion which is to make extrusion on the matching cables of synchronous displacement to make its oversheath one-time adhered to the oversheath of the center cables, cooling, drying and draughting, as well as the looping and wire collection. By adopting the forming way of adhesion, the said method makes the matching cables directly adhered to the oversheath of the enter cables paralleled through synchronous extrusion when the oversheath is extruded on the center cables. The method has the advantages of simple manufacturing process, compact structure, saving in material and convenient branching. With the idler pulley, the matching cables are adhered to the center cables without any other caking agent, which guarantees an environmentally friendly utilization. Besides, the center cables are in parallel with the matching cables with the oversheath without intertwisting, which has little impact on performance of each of the composite cables.
Description
(1) technical field
The present invention relates to the preparation method of the comprehensive cable that a kind of comprehensive wiring system uses.
(2) background technology
Along with the development of digital technology and the raising of people's living standard, digitlization, intellectual communityintellectualized village and dwelling house are more and more, wiring cable will have language, image, transfer of data and network broadband access etc. simultaneously, this just requires various cables to carry out comprehensive wiring, and considers construction and wiring problem as far as possible.Existing comprehensive cable is that various cable units are twisted in the several protecting pipes that are coated on same protecting pipe behind the stranding or are arranged in parallel, complex manufacturing technology, and product cross section is long-pending big, and consumptive material is many, the cost height; And, be a kind of permanent deformation, thereby influence the serviceability of whole cable because strand all has certain influence to structure to the cable core inner structure that does not coat restrictive coating as yet; In addition, use inconvenience, when needs separately use each cable unit, the branch operation difficulty; The molding mode of existing another kind of comprehensive cable is with glue each cable unit to be bonded together, and operation easier is big, not environmental protection, and since each cable unit lopping radius difference cause can't lopping.
(3) summary of the invention
For solve existing comprehensive cable manufacturing process complexity, not environmental protection and cable unit lopping radius different and cause can't lopping shortcoming, the invention provides a kind of preparation method who is easy to the comprehensive cable of lopping by simple to operate, environmental protection and cable.
For this reason, the present invention takes following technical scheme:
A kind of preparation method of comprehensive cable, described comprehensive cable is made up of some cables that have external sheath layer that are arranged in parallel, comprise the steps: (1), select materials: selected as required several wire cable also is arranged in parallel, selected a kind of cable is the center cable, other cables are supporting cable, described center cable is to extrude external sheath layer semi-finished product cable before, and described supporting cable is through extruding the finished product cable of external sheath layer; (2), crowded cover is absorbed in: when the center cable extrudes external sheath layer, the supporting cable of extruding synchronous shift, make the disposable center cable external sheath layer that is absorbed in of external sheath layer of supporting cable, described step is undertaken by following mode: the guide wheel that is provided with the supporting cable of some extruding in the periphery of center cable, the wheel shaft of described guide wheel and center cable are arranged vertically, described guide wheel is adjacent to extrude machine and the correspondence machine of extruding and exports a side and arrange, supporting cable is arranged between guide wheel and the center cable, at first regulate guide wheel and center cable spacing from, then, when the center cable extrudes external sheath layer, guide wheel pushes the supporting cable of synchronous shift, makes the disposable center cable external sheath layer that is absorbed in of external sheath layer of supporting cable; (3), the cooling of the cable set after being absorbed in, drying; (4), with dried cable set traction; (5), lopping, take-up.
Also include step (41) between step (4), (5): twisting: the cable set through pulling out is carried out twisting.
The bosh cooling is adopted in cooling in the step (3), and the dry air-dry machine that adopts dries up.
Traction adopts caterpillar-tractor to draw in the step (4).
S-Z strand mode twisting is adopted in twisting in the step (41).
Advantage of the present invention is: 1, adopt to squeeze to overlap to be absorbed in the formula molding mode, when the center cable extrudes external sheath layer, by synchronous fashion of extrusion, supporting cable directly is absorbed on the parallel with it center cable oversheath, and production technology is simple, compact conformation, save material, branch is convenient; 2, by guide wheel work supporting cable is trapped in the center cable, need not other binding agents, use environmental protection; 3, the center cable is arranged in parallel with the supporting cable with external sheath layer, does not need twisting step, and is little to each cable unit performance impact of comprehensive cable; 4, for the comprehensive cable of unsymmetric structure, adopt S-Z twisting lopping, solved each cable unit lopping radius of comprehensive cable different and cause can't lopping a difficult problem, and, when construction is used, each cable unit of comprehensive cable after S-Z strand can automatically restore to parastate, does not influence the serviceability of each unit.
