Mould seat for compressing cable conductor

Abstract

The invention discloses a mould seat for compressing a cable conductor. The mould seat comprises two longitudinal symmetry pinch roller seats. Each pinch roller seat comprises a U shape pedestal, an inner cavity of the pedestal is provided with a compression mould, and sidewall holes at two sides of the pedestal are provided with a bearing respectively. An outer end of each bearing is provided with a rounded seal-capping respectively. An outer circumference of each rounded seal-capping is threadingly connected with a sidewall of the pedestal. The rounded seal-capping, the bearings and the compression mould are coaxially arranged and a common mandrel is shared. Opening parts of the U shape pedestals of the two pinch roller seats are face-to-face. Opposite cylindrical surfaces of the two compression moulds form a combination work unit which carries out compression on the cable conductor. The mould seat in the invention has the characteristics of convenient installation, easy adjustment, good quality of a compressed cable conductor, symmetry compressed conductors and the like.

Description

Technical field: [0001] The invention relates to a mold seat for pressing a cable conductor. Background technique: [0002] As we all know, the most important part of the cable is the conductor. When the cable has two cores or more, the conductor must be processed into special-shaped conductors, such as semi-circular, fan-shaped and tile-shaped, so that these conductors are extruded and insulated. The cable is formed into a circle to reduce the outer diameter and gap of the cable, reduce the filling material and sheath material of the cable, and reduce the production cost of the cable. [0003] When the cable conductor is produced and compressed, if the upper and lower conductor compression molds cannot be aligned, no matter how good the other conditions are, it will not be possible to produce high-quality conductors, and it is easy to damage the conductor compression mold. If the conductor production is not good, no matter how it is produced later Affect the appearance and...

Problems solved by technology

[0003] When the cable conductor is produced and compressed, if the upper and lower conductor compression molds cannot be aligned, no matter how good the other conditions are, it will not be possible to produce high-quality conductors, and it is easy to damage the conductor compression mold. If the conductor production is not good, no matter how it is produced later Affect the appearance and quality of the cable

[0004] At present, in our country, the mold base with the following structure is used in the production of conductor compression, see image 3 , 4 , this kind of structure is that the bearing 2 is fixed in the fixed base 1, and cannot freely enter and exit from the side holes on both sides of the fixed base 1, and between the bearing 2 and the compression mold 4, there is a bushing 3 that presses against the conductor compression mold , the mold seat of this structure, its bearing, bushing and conductor compression mold are fixed and cannot be adjusted left and right, and the outer dimensions of the conductor compression mold, bushing and bearing must be deviated during processing, and they are assembled in At the same time, the conductor compression mold will shift to the left and right in the fixed base, the conductor compression molds in the upper and lower fixed bases cannot be aligned, and the gap between the conductor compression molds is very small when they are aligned, rotated and pressed. Yes, there is even no gap. If the top and bottom are not aligned, the forced rotation will not only produce asymmetrical conductors, damage the conductors, but also cause damage to the conductor compression mold.

Especially when the compression mold wears a lot during use, it is more difficult to align the upper and lower compression molds, and the forced production and use are more likely to cause damage to the compression mold and quality problems in conductor compression

[0005] The installation and use of this kind of mold is also inconvenient. When the conductor compression mold and the bushing are installed together, the conductor compression mold and the two bushings are independent and movable relative to the U-shaped fixed base. , it is more difficult to use the mandrel 5 to sequentially string the conductor tightly to the mold, the two bushes and the two bearings concentrically. This requires slow installation by hand, which takes time and effort, reduces installation efficiency, and delays production.

[0006] Once this kind of old-fashioned mold holder is installed in the mold holder frame, the position of the pressing mold cannot be adjusted online. It must be disassembled and readjusted, which is time-consuming and inefficient.
