Description
Technical field
The utility model belongs to electric wire production technical field, is specifically related to a kind of watt shape electric wire compact conductor mould.
Background technology
Reduce costs to save material, cable conductor core generally adopts and presses structure, and particularly for extrusion type cable, Insulation Material is got into gap between line and prevented moisture from entering core under pressure during in order to avoid extruding or time crosslinked, therefore adopts compact wire.That produces round conductor in industry presses general employing pinch roller and compressing mold two kinds of modes, and special-shaped conductor generally adopts pinch roller.But produce special-shaped conductor with pinch roller in actual production and there is following problem:
1. when producing, the gap of pinch roller is not easily measured and adjusts, and different operating personnel are different to the clearance control of pinch roller according to respective experience, easily cause the conductor appearance and size of production to change;
2. in actual production due to the conductor profile variation that pinch roller is produced, the cross section of conductor and D.C. resistance index be fluctuation and then, causes and increases the quality of product and cost control difficulty;
3., because pinch roller is assembly parts, easily produce lower pressure wheel dislocation or malposition when assembling not in place or component wear, the conductor of production may produce the problem such as out-of-shape, overlap.If special-shaped conductor can use special-shaped compressing mold, so conductor size can be controlled more accurately than pinch roller, and smooth surface, the problem such as impression, overlap can not be gone out.And use special-shaped compressing mold can produce mould fragile, produce in single line easily jump stock and cause broken string, and threading is very difficult, operates the problems such as bothersome effort.
Utility model content
Utility model object: the purpose of this utility model is to solve deficiency of the prior art, provides a kind of impulsive force when greatly can strengthen stretching, thus greatly can increase watt shape electric wire compact conductor mould in mold use life-span.
Technical scheme: one described in the utility model watt shape electric wire compact conductor mould, comprise core rod and die sleeve, the center of described core rod is provided with a watt shape hole, this mould collection doubling, presses and is structure as a whole, and is divided into upper die and lower die two mold-opening structure, described patrix includes mouth region, deformed area, sizing area, outlet area and fovea superior profile, described counterdie comprises lower convex face, and described fovea superior profile is connected with described lower convex face adaptation.
Further, described core rod adopts spark stone structure, and described die sleeve adopts high-speed tool steel construction.
Further, the cross section of described inlet region is the bell-mouth structure of air that reduces gradually of aperture from outside to inside, and bell mouth angle is 40-60 °.
Further, the cross section of described deformed area is watt shape mouth structure that internal diameter reduces gradually, chamfering 2-3mm, and a watt shape angle is 15-25 °, and length is 0.4-0.6H, and wherein H is mould total height.
Further, the cross section of described sizing area is rectangle structure, chamfering 2-3mm, and length is 0.45-0.55d, and wherein d is the diameter of sizing area.
Further, the cross section of described outlet area is the bell-mouth structure of air that reduces gradually of aperture from outside to inside, and bell mouth angle is 50-60 °.
Further, the length of described core rod in described die sleeve accounts for the 1/2-2/3 of whole die sleeve total length.
Beneficial effect: the utility model reasonable in design, adopt upper and lower mould structure, upper and lower two die sinkings designs overcome traditional pressure roller greatly, and to wear the mould time long, the shortcomings such as the difficult control of external diameter, and collection doubling, press and be structure as a whole, undertaken by each layer that watt shape is stranded adds the process of watt shape, greatly strengthen impulsive force when stretching, thus can greatly increase the mold use life-span.

Detailed description of the invention
One watt shape electric wire compact conductor mould as shown in Figure 1-Figure 3, comprise core rod 1 and die sleeve 2, the center of described core rod 1 is provided with a watt shape hole 3, this mould collection doubling, presses and is structure as a whole, and is divided into upper die and lower die two mold-opening structure, described patrix includes mouth region 4, deformed area 5, sizing area 6, outlet area 7 and fovea superior profile 8, described counterdie comprises lower convex face 9, and described fovea superior profile 8 is connected with described lower convex face 9 adaptation.
As the further optimization of technique scheme, described core rod 1 adopts spark stone structure, and described die sleeve 2 adopts high-speed tool steel construction.The cross section of described inlet region 4 is the bell-mouth structure of air that reduces gradually of aperture from outside to inside, and bell mouth angle is 40-60 °.The cross section of described deformed area 5 is watt shape mouth structure that internal diameter reduces gradually, chamfering 2-3mm, and a watt shape angle is 15-25 °, and length is 0.4-0.6H, and wherein H is mould total height.The cross section of described sizing area 6 is rectangle structure, chamfering 2-3mm, and length is 0.45-0.55d, and wherein d is the diameter of sizing area 6.The cross section of described outlet area 7 is the bell-mouth structure of air that reduces gradually of aperture from outside to inside, and bell mouth angle is 50-60 °.The length of described core rod 1 in described die sleeve 2 accounts for the 1/2-2/3 of whole die sleeve 2 total length.
