Abstract
The utility model discloses a rolling template of helical copper tube flexible coaxial radio frequency cable in the technical field of cable process equipment, comprising a transition section, a leading section and a sizing section which are integrated and distributed in helix; internal sides of the transition section, leading section and sizing section are provided with continuous working curve; the curvature radius of the working curve gradually reduces from the start point of the transition section to the end point of the leading section; the curvature radiuses on the sizing section are equal; the sizing section is not less than 1/2 circumference on the circumferential direction. When working, the rolling template is mounted on the mould; one end of the copper tube is inserted into the hole formed by the working curve from one side of the transition section such that the mould and the copper tube oppositely rotate and axially propel, so a continuous helical groove is rolled on the surface of the copper tube; the utility model has simple structure, large rolling efficiency and can ensure the flexibility of the cable and the stability of each parameter and has high production efficiency. The device is specially used for the production of helical copper tube flexible coaxial radio frequency cable.
Description
Technical field
The utility model relates to the mould that a kind of cable is produced, and belongs to the cable technical field of processing equipment.
Background technology
In the prior art, the 3GMz spiral copper pipe super-flexible coaxial radio frequency cable, its top and bottom that is mainly used in the mobile communication launching tower is as connecting line, require it to have softness and be easy to crooked characteristic, bending radius is smaller or equal to 15cm, for this reason, its cable can adopt following method production: after insulation heart yearn outside adopts mould that the copper strips of 0.21mm is bent to smooth cylindrical duct earlier, with argon arc welding seam crossing is welded again, with rolling mould smooth copper is rolled into surperficial spiral outer conductor then, then, outside outer conductor, extrude the layer of polyethylene sheath, can become finished cable.
The utility model content
The purpose of this utility model provides a kind of rolling mold sheet of spiral copper pipe super-flexible coaxial radio frequency cable, utilizes this rolling mold sheet can produce spiral copper pipe super-flexible coaxial radio frequency cable fast and efficiently.
The purpose of this utility model is achieved in that the rolling mold sheet of spiral copper pipe super-flexible coaxial radio frequency cable, comprise the changeover portion, introducing section and the sizing section that distribute twist and be connected as a single entity, the inboard of changeover portion, introducing section and sizing section is provided with continuous working curve, the radius of curvature of described working curve reduces to the terminal point of introducing section gradually from the changeover portion starting point, radius of curvature on the sizing section equates that everywhere described sizing section is not less than 1/2nd circumference in a circumferential direction.
During the utility model work, rolling mold sheet is installed on the mould of roll mill, one end of the smooth copper that welding is good inserts the formed hole of working curve from changeover portion one side, make relative rotation of mould and while axial advance, so just can roll out a continuous spiral slot in copper pipe surface with copper pipe; Then, extrude the layer of polyethylene plastics in copper pipe surface again, become finished cable.The utility model is simple in structure, and rolling power is big, can guarantee that cable softness and parameters are stable, and in the operation of rolling, copper pipe is stressed evenly, and is rolling quick, the production efficiency height.The utility model is exclusively used in the production of spiral copper pipe super-flexible coaxial radio frequency cable.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of rolling mold sheet among Fig. 1.
Wherein, 1 changeover portion, 2 introduce section, 3 working curves, 4 sizing sections.
Embodiment
As Fig. 1 and 2, rolling mold sheet for spiral copper pipe super-flexible coaxial radio frequency cable, comprise the changeover portion 1, introducing section 2 and the sizing section 4 that distribute twist and be connected as a single entity, the inboard of changeover portion 1, introducing section 2 and sizing section 4 is provided with continuous working curve 3, the radius of curvature of described working curve 3 reduces to the terminal point of introducing section 2 gradually from changeover portion 1 starting point, radius of curvature on the sizing section 4 equates that everywhere described sizing section 4 is not less than 1/2nd circumference in a circumferential direction.
During work, rolling mold sheet is installed on the mould of roll mill, one end of the smooth copper that welding is good inserts the working curve 3 formed holes from changeover portion 1 one sides, make relative rotation of mould and while axial advance, so just can roll out a continuous spiral slot in copper pipe surface with copper pipe.
