Leaky cable longitudinally-wrapped cavity forming platform

Abstract

The invention discloses a leaky cable longitudinally-wrapped cavity forming platform which comprises a longitudinal-packaged platform. A first longitudinally-wrapped forming die, a second longitudinally-wrapped forming die, a longitudinally-wrapped forming conical tube, an overlapping die, a first sizing die and a second sizing die which are coaxial are installed on the longitudinally-wrapped platform in sequence, wherein die cavities of the first longitudinal-wrapped forming die and the second longitudinally-wrapped forming die are connected into a wholly streamline-shaped die cavity; a core shaft bracket is installed on the longitudinally-wrapped platform; and a core shaft is installed on the core shaft bracket, is positioned in the streamline-shaped die cavity and is matched with the first longitudinally-wrapped forming die and the second longitudinal-wrapped forming die to form a longitudinally-wrapped cavity. The leaky cable longitudinal-wrapped cavity forming platform has the beneficial effects that as a copper strip can not transversely swing in the forming process, the problems of slot deformation, copper strip breaking and position change of the copper belt are completely solved, so that the product quality is improved, and the higher uniformity is achieved; and under the existence of a furred tongue, the two sides of the copper strip are always positioned at the same position, so that the crossed turnover and folding is avoided, and the qualified rate of products is improved.

Description

technical field [0001] The invention relates to a mold for the communication cable manufacturing industry, in particular to a leaky cable longitudinal wrap cavity forming platform. Background technique [0002] Leaky cable is the abbreviation of leaky coaxial cable (Leaky Coaxial Cable), which consists of four parts: inner conductor, insulating medium, outer conductor with periodic slots and sheath. During the transmission of the radio frequency signal inside the leaky cable, a part of the radio frequency signal is coupled to the external space through the outer conductor hole; the radio frequency signal in the outer space can also be coupled to the inside of the cable through the outer conductor hole. Therefore, the leaky cable has the dual functions of a radio frequency signal transmission line and a transceiver antenna. It is generally used in specific spaces where communication antennas are difficult to function, especially in specific spaces where separate antennas in ...

AI Technical Summary

Problems solved by technology

The longitudinal wrapping platform is the reference working platform, and its surface is flat. The first longitudinal wrapping die, the second longitudinal wrapping die, the longitudinal wrapping cone, the lapping die, and the first sizing die are successively installed on the longitudinal wrapping platform. , and the second sizing die, the first longitudinal wrapping die and the second longitudinal wrapping die cooperate to form an inner streamlined mold cavity, a mandrel is fixed in the die cavity, and the mandrel is fixed on the longitudinal On the wrapping platform, the gap space between the mandrel and the mold cavity is used as the movement forming space of the copper strip. After the copper strip passes through the mold cavity, the copper strip and the cable core enter the longitudinal wrap forming conical cylinder at the same time, and then pass through the overlapping die, After the first sizing die and the second sizing die come out, the copper tape is wrapped longitudinally on the cable core to form the outer conductor of the leaky cable, and then squeezed on the sheath synchronously to form a leaky cable. Compared with the current process die, the present invention The leaky cable after processing, because the copper strip will not swing left and right during the forming process, completely solves the problems of copper strip slot deformation, copper strip breakage and position change, which improves product quality and achieves higher uniformity sex
