本发明的目的是提供一种汽车减速器行星复合齿轮组合结构和锻压模具，以解决现有技术存在的问题。
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。
如图1-4所示，本发明提供一种汽车减速器行星复合齿轮组合结构，包括外套层1和芯体2，所述外套层1内壁设置有内波纹3，所述芯体2外壁设置有和所述内波纹3相配合的外波纹4。
本发明所述外套层1为钢材料制成。
本发明所述芯体2为铝合金材料制成。
本发明所述内波纹3和外波纹4呈锯齿状设置；
结构原理：
所述外套层1采用不锈钢材料制成，如不锈钢316L，工具钢42CrMo,所述芯体2采用铝合金材料制成，如型号为5083、7075等；
将所述外套层1和芯体2加热至不同温度的热塑状态，瞬速将外套层1和芯体2组合完毕后的齿轮坯料放入至锻压模具内；
内波纹3和外波纹4相互卡设安装，提高外套层1和芯体2之间的接触面积，提高摩擦强度，加强结合的稳定性。
具体的加工方法：
铝/钢主要是在温度和压力的共同作用下固相连接，被连接材料通过充分接触和局部塑性变形，以及材料相互之间元素扩散或反应形成牢固的冶金结合面。
在复合锻压之前，外套层1需要提前通过加热炉或电磁感应加热设备加热到850-950℃之间，内侧铝合金芯体2也同样需要加热到550-600℃之间，让内外侧材料之间充分结合；
1、先制成具备外波纹4的芯体2和具备内波纹3的外套层1；
2、然后分别将外套层1和芯体2加热至可塑型温度；
3、瞬速将所述芯体2放入至外套层1内，利用铝合金和钢处于热塑态时具备良好的流动性，实现了铝合金芯体2和钢材料外套层1的协调变形，使符合构件截面结合质量更好。

结构原理，将上述复合制造完毕的齿轮胚料放入至固定下模组6内，启动动力组件，使所述活动上模组5朝所述固定下模组6内表面下压并合并，合并后固定下模组6和活动上模组5内部形成齿轮轮廓，并将所述齿轮胚料锻造成特定齿轮形状；同时，在所述固定下模组6和活动上模组5闭合后，由于锻压的作用力，上模顶针组件8和下模顶针组件10收缩；
脱模时，活动上模组5远离所述固定下模组6，此时成型后的齿轮可能会贴合于固定下模组6或活动上模组5表面，为了使齿轮能顺利从固定下模组6或活动上模组5表面顶出则继续驱动所述活动上模组5上移，当移动到顶部后，此时上顶针触发组件9和所述上模顶针组件8配合触碰，上模顶针组件8向外顶出，将处于所述活动上模组5表面的齿轮顶出，触发顶压结构11和下模顶针组件10配合，使固定下模组6内的下模顶针组件10向外顶出，将处于所述固定下模组6表面的齿轮顶出；完成完全脱模；
