A manufacturing process of a feed element

Abstract

The invention relates to the field of communication equipment production, and in particular proposes a manufacturing process for a feeding element. The process adopted is not lathe machining, but a process scheme combining cold heading process and mold clamping process. In the manufacturing process, not only alloys can be used It can also be processed with pure metal with poor strength such as copper. For example, when copper is processed, its rod-shaped raw material will only be processed by the processing equipment at the end, and other parts have the first strip clamp. The hole or the second strip clamping hole is clamped, so the technical axis receives external force and will not deform, so as to ensure the machining accuracy of the product; in addition, the shapes of the cold heading die and the clamping die are also It can be designed or replaced according to product design or application needs, more kinds of products can be produced by using the manufacturing process, and the product precision, quality and production efficiency are also greatly improved.

Description

technical field [0001] The invention relates to the field of communication equipment production, in particular to a manufacturing process of a feed element. Background technique [0002] The product quality of the radiation unit in the base station antenna industry is very important, and the feed element will directly affect the product quality of the radiation unit, so the structure design of the feed column itself and the installation structure design of the feed column and other installation positions of the radiation unit are very important. important. [0003] The product quality of the radiation unit is not guaranteed in the prior art. Those skilled in the art have made a lot of technical research and development, such as the Chinese patent whose patent announcement number is CN110994179A, which discloses a feed assembly and a radiation unit; wherein the radiation unit is It includes a dipole, a balun structure and a feeding part, wherein the radiating unit is located...

Problems solved by technology

[0004] Due to the shape and precision requirements of the feeder column, the existing feeder column is processed by a lathe, but the lathe processing freedom is limited, and the processing time and cost are relatively high, so the lathe can only be used to produce a dumbbell-like shape. The basic structure, such as in the Chinese patent application number 201911422004.8, the feeder column image 3 As shown, the feed column body and the terminals respectively arranged at both ends of the feed column body, the radial dimension of the terminal is larger than the radial dimension of the feed column body, and the terminal is a regular cylinder obtained by lathe processing. Shaped structure; because there is not only one feeder part, and the extension direction of the inner wires of multiple feeder parts on the terminal is not consistent, and there is an angle between each other; and the inner conductor of the feeder part and the outer conductor The extension direction of the inner conductor of the cable on the terminal of the feed post also has a specified angle; if the end face of the terminal of the feed post is in a flat structure, it is difficult to ensure that the welding structure between the inner conductor and the terminal is sufficiently firm and the position is accurate ; At the same time, because the extension length of the inner conductor is limited, if the inner conductor cannot be welded to the terminal accurately according to the inherent angle between the power supply part and the external cable, it is easy to cause that the inner conductor cannot be welded accurately and firmly on the specified On the terminal, even if multiple internal conductors are forcibly welded to the specified terminal under the action of external force, due to the pulling effect between some internal conductors and the terminal, it is easy to fall off or be damaged after a long time. Such a welding structure and method are also Greatly increased the difficulty of the actual assembly operation of the launch unit
