Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cable core cross-section figure behind the utility model insulated wire cores stranding.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model improves the device of fan-shaped insulated wire cores stranding quality, comprise insulated wire cores 4 and stranding doubling mould 5, described insulated wire cores 4 is drawn to stranding doubling mould 5 by distributor plate 2, and the both sides of distributor plate 2 are respectively equipped with vertical minute wire carrier 1 and level is divided wire carrier 3.Wherein, insulated wire cores 4 is fan-shaped crosslinked polyetylene insulated core, the fan-shaped arc surface of insulated wire cores 4 outwardly, drift angle inwardly, and stranding doubling mould 5 is the doubling mould of 25～30mm for inlet wire district horn mouth chamfer radius.
The structure of the utility model stranding doubling mould considers that silane crosslinked insulating is a thermosets, and its material is harder, and fan-shaped insulated wire cores ftractures when entering stranding doubling mould easily, and is therefore particularly important to the control at insulated wire cores progressive die angle.Should increase contact-making surface during the insulated wire cores progressive die as far as possible, reduce the internal stress that insulated wire cores produces because of torsion.Mould bases is wanted suitably (as shown in Figure 1) apart from the distributor plate distance, and too small as distance, the progressive die angle beta of insulated wire cores is excessive, and the easy damaged insulation produces insulation and breaks.Therefore, inlet wire district horn mouth with stranding doubling mould during design suitably strengthens, and horn mouth chamfer radius R adds greatly 25～30mm by original 20mm, and by adjusting the distance of mould bases and distributor plate, strict control insulated wire cores progressive die angle is to reach good stranding effect.Simultaneously, the project organization of distributor plate stands up for preventing fan-shaped core insulated wire cores in the stranding process, adopts fixed stranding, makes fan-shaped drift angle align the geometric center (as shown in Figure 2) of cable all the time, to guarantee the rounding of stranding diameter.The level that installs the fixed insulation core on distributor plate additional is divided wire carrier and vertical branch wire carrier, to reduce eccentric angle, avoids making because of torsion is excessive insulation to stand up and break.
When fan-shaped insulated wire cores stranding, earlier with core pretwist 1～2 circle, again core is drawn to stranding doubling mould by distributor plate, about distributor plate, divide wire carrier static line core position with vertical wire carrier and the level of dividing respectively, all the time be the geometric center that fan-shaped drift angle aligns cable when making fan-shaped core enter the doubling mould, be fan-shaped arc surface outwardly, drift angle is (as shown in Figure 2) inwardly.Fig. 2 is the cable core cross-section figure behind the fan-shaped insulated wire cores stranding of three cores, the fan-shaped minor axis a of fan-shaped insulated wire cores is vertical with fan-shaped major axis b, wherein fan-shaped minor axis a should overlap with the cable symmetry axis by the geometric center of cable, if depart from then and form the r angle with symmetry axis, the r angle is called eccentric angle, usually eccentric angle should not be greater than 10～15 °, otherwise will influences the Electric Field Distribution of cable, and bigger internal stress and torsion will make insulation ftracture.Divide wire carrier (as shown in Figure 1) by the vertical minute wire carrier and the level that install the fixed insulation core about distributor plate additional, reduce eccentric angle, the insulation of having avoided causing because of torsion is excessive is broken.
The utility model stands up when having solved fan-shaped insulated wire cores stranding, the critical technological point of damage in insulation cracking, reduce the pretwist (than original 1～2 circle that reduces) of fan-shaped core simultaneously, alleviated operative employee's labour intensity, be applicable to that the stranding operation of fan-shaped cross-linked polyethylene insulated cable is produced.
