Abstract
The utility model relates to a sector-shaped conductor compressing mold, and is suitable for the wire and cable manufacturing industry. The sector-shaped conductor compressing die comprises a hard alloy mold core and a steel bushing inlaid on the mold core, and is characterized in that the middle of the hard alloy mole core is provided with a sector-shaped hole. The hard alloy mold core is divided into a wire inlet zone, a deformation zone, a sizing zone and a wire outlet zone, the wire inlet zone is a circular horn mouth, the deformation zone is a sector-shaped horn mouth, the sizing zone is a sector-shaped hole, and the wire outlet zone is a sector-shaped arc chamfer. The sector-shaped conductor compressing mold has the following advantages: 1. The shaped and size of a conductor produced by the sector-shaped conductor compressing mold are stable, reducing the usage amount of conductor material; and 2. The conductor produced by the sector-shaped conductor compressing mole has a smooth surface, and a flange of the conductor can be eliminated, improving product quality.
Description
Technical field
The utility model relates to a kind of electric wire twisted wire mould, and specifically a kind of sector conductor presses mould, and it is applicable to the electric wire manufacturing.
Background technology
In the electric wire of multicore structure, adopt the electric wire of sector conductor to account for very big proportion, sector conductor uses the mode of pinch roller to produce always, the installation of pinch roller and a large amount of time and labor of adjusting cost, geomery, the conductor weight of the sector conductor that the pinch roller that different time different operating personnel regulate is produced differ greatly, the spacing of regulating causes waste of material greatly, intangibly increased material cost, make the few or loss of capital of product profit, the spacing of regulating causes conductor resistance big for a short time, and product is defective.Pinch roller use for a long time can cause wearing and tearing, and the conductor of producing is easy to generate overlap, produces the breakdown mass defect of cable insulation.
Summary of the invention
The present invention is exactly that a kind of sector conductor that provides in order to address the above problem presses mould, control in reasonable range with the conductor overall dimension that it is produced, conductor weight is also controlled in reasonable range, reduce cost, can eliminate overlap, the smooth no mass defect of conductive surface.
The technical solution of the utility model is achieved in that it comprises carbide alloy core rod and the steel bushing that is set on the core rod, and it is characterized in that: the centre of carbide alloy core rod has fan-shaped hole.Described carbide alloy core rod is divided into inlet wire district, deformed area, sizing area and cable connecting area, and the inlet wire district is the round speaker mouth, and the deformed area is the sectoral horn mouth, and sizing area is scallop hole, and cable connecting area is fan-shaped arc angling.
The utility model adopts Hardmetal materials to be set in the steel bushing through after the machine-shaping, and core rod divides inlet wire district, deformed area, sizing area and cable connecting area, and conductor is applied certain pulling force, makes it produce distortion by core rod, obtains the higher sector conductor of precision.
Its operation principle is: utilize the plasticity of metallic conductor, make tension stress greater than the metal deformation drag in pulling process, thereby produce plastic deformation.
The utlity model has following advantage:
1, sector conductor presses the conductor shape dimensionally stable that mould is produced, and reduces the use amount of conductor material.
2, to press the conductive surface that mould produces smooth for sector conductor, can eliminate the overlap of conductor, improves the quality of products.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As Fig. 1, shown in Figure 3, the utility model comprises carbide alloy core rod 1 and the steel bushing 2 that is set on the core rod, and the centre of carbide alloy core rod 1 has fan-shaped hole 3.Described carbide alloy core rod 1 is divided into: inlet wire district 4, deformed area 5, sizing area 6 and cable connecting area 7, and inlet wire district 4 is the round speaker mouth, and deformed area 5 is the sectoral horn mouth, and sizing area 6 is fan-shaped, and cable connecting area 7 is fan-shaped arc angling.
Conductor dbus is crossed inlet wire district, deformed area, sizing area and the cable connecting area that passes through the carbide alloy core rod behind the noseplate of wire twisting equipment successively, and conductor is applied certain pulling force, makes it produce distortion by core rod, obtains the higher sector conductor of precision.
