一、前言 矩形喇叭是雷达天线馈源中的一个重要元件。喇叭内表面平直度及光洁度都要求很高。矩形喇叭成型法一般有三种:旋压冲压法、电铸成型法、拼焊成型法。旋压冲压法适用于批生产,用旋匡冲压工艺成型,速度快、效率高,但需专用设备及模具,电铸成型法适于单件试制,虽能一次成形,得到满意的精度及光洁度,但周期长、效率低;拼焊成型法适用于单件试制
I. Introduction Rectangular speaker radar antenna feed is an important component. Horn flatness and surface finish are demanding. Rectangular horn molding method generally has three kinds: spin stamping method, electroforming method, welding method. Spinning stamping method is suitable for batch production, with the spinstock stamping process molding, fast, high efficiency, but need special equipment and molds, electroforming forming method suitable for a single trial, although a single forming, to be satisfied with the accuracy and finish , But long cycle, low efficiency; tailor-welded forming method for a single trial
