该弯管模 4是一种能够一次性实现弯管与切割的、 具有多层模腔结构的弯管模 4。 附属夹模 40， 作为主夹模 5附属部分， 设置在主夹模 5旁边， 将主夹模 5上的模腔 设在附属夹模 40侧面上， 上下两个螺钉 60穿过主夹模 5的通孔， 固定在附属夹模 40 上， 每个螺钉 60上套有弹簧 70， 使弹簧 70支撑在附属夹模 40和主夹模 5之间， 形成 一弹性预压机构 80， 并设置连接附属夹模 40和主夹模 5之间， 这样通过移动主夹模 5， 带动附属夹模 40进给， 压缩弹簧 70， 利用弹簧形变产生的力来预夹紧管件。
当然， 弹性预压机构也可以设计成其他结构， 如图 8所示为弹性预压机构的另一实 施例， 其中， 上下两个导向杆 11， 穿过主夹模 5的通孔， 连接在附属夹模 40的导向孔 内， 弹簧 70， 套在导向杆 11上， 并支撑在附属夹模 40和主夹模 5之间， 螺钉， 穿过主 夹模 5上的导向槽孔 2.1， 固定在导向杆 11上。 也能获得类似技术效果。
这样， 本发明通过在主夹模 5上安装一个切管机构以及一个预夹紧管件的附属夹模 40， 可以实现弯管与切割一次性完成， 缩短了生产工序， 降低生产成本， 提高效率。
