Brief description of the drawings:
Fig. 1 is the structural representation of the specific embodiment of the invention.
In figure, wireway centered by 1,2 is control signal wire, and 3 is thin copper wire strand, and 4 is polyolefin oversheath.
Detailed description of the invention:
For the technical characterstic of explanation this programme,,, be further elaborated in conjunction with accompanying drawing above the specific embodiment of the present invention below by one.
With a welding torch cable that pushes away for gas shield, preparation process is as follows:
(1) extrude central airway: adopt cross-linking radiation polyolefine material to extrude, strictly by given external diameter value and the wall thickness value of technique, control external diameter and the wall thickness of wireway well. About the size of controlling external diameter and wall thickness, different size is shown in list 1. Extrude after cooling and carry out cross-linking radiation. Irradiation dose is 130-160kGy; Why select cross-linking radiation polyolefine material to manufacture wireway, the one, it belongs to environment-friendly materials, can enter European & American Market; The 2nd, after cross-linking radiation, polyolefine material has very high resisting expansion strength, can long-time bearing air pressure and indeformable. Cross-linking radiation polyolefine material, hardness > 90ShoreA, hot strength > 14MPa, elongation at break > 350%.
(2) central airway after cross-linking radiation will be injected the atmospheric gas of 0.1～0.2MPa, by sealed at both ends, until after the whole whole completion of processing of cable, then discharge gas. Object is to prevent from twisting system at conductor, controlling in the processes such as core strand is made, oversheath extrudes, and cable has the phenomenon that is pulled belt flattening to occur. Because of the necessary rounding of external diameter of this cable, can not there is a null ellipse phenomenon.
Manufacturing of (3) two control signal wires: extrude with φ 45 or φ 65 extruders, the Optimal Control temperature in the each region of extruder fuselage is: 110 DEG C, a district, 130 DEG C, 2nd district, 155 DEG C, 3rd district, 165 DEG C, 4th district, 165 DEG C-175 DEG C of head temperatures, mould adopts plsitive mold, after becoming line, carry out irradiation, irradiation dose is 110-130KGY, and heat extension is controlled between 50%-80%, after irradiation, must carry out spark machine test, determine without electric leakage and just can use by stranding; Two control signal wires adopt 125 DEG C of LSOH anti-flaming irradiation Insulation Material, its hardness > 80ShoreA, hot strength > 12MPa, elongation at break > 150%.
(4) conductor is stranded: be the many thin copper wire strands of φ 0.16mm by filament diameter good synnema, together with two ready-made control signal cores of system, be stranded in equably on central airway outer wall. Stranded upper being very easy to, but to ensure that stranded rear whole some bending of cable all can not have, be the straight-tube shape of a standard, very difficult. Because be stranded on a flexible pipe, flexible pipe itself is just easy to bending. So, when stranded, will note adjusting the expansive force of every strand, otherwise the cable after stranded is easy to occur snakelike curved phenomenon, causes whole cable to be scrapped. The emphasis of this process is the control expansive force of each drum to be adjusted into equally size. Otherwise the not rounding of conductor after stranded, has snakelike curved.
(5) manufacturing of polyolefin oversheath: in stranded good conductor and control signal core outside, then extrude 125 DEG C of cross-linking radiation polyolefin elastomers of one deck; Extrude with φ 90 or φ 120 extruders, the Optimal Control temperature in the each region of extruder fuselage is: 85 DEG C, a district, 95 DEG C, 2nd district, 105 DEG C, 3rd district, 120 DEG C, 4th district, 125 DEG C, 5th district, and head 125-128 DEG C, mould adopts squash type or half squash type. Described cross-linking radiation polyolefin elastomer, its hardness > 80ShoreA, hot strength > 10MPa, elongation at break > 180%.
(6) cross-linking radiation: the cable that has extruded polyolefin oversheath is carried out to cross-linking radiation, and irradiation dose is 110-130KGY, heat extension is controlled between 25%-50%;
(7) lettering will carry out after oversheath irradiation finishes, in case font distortion. Lettering fixture installs respectively two of lower tumblers additional before and after type wheel, firmly by fixing point-blank to cable and type wheel, in case font distortion. The ink adopting is volatile type.
