具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部 分实施例，而不是全部的实施例。
一种用于定子扁线19的折弯装置，包括机架，所述机架上转动设有一凸轮3，所述凸轮3水平设置，所述凸轮3包括中心圆5，所述中心圆5的圆心为凸轮3的转动中心，所述中心圆5的侧壁上向外凸出至少一个圆弧状凸起6，位于中心的中心圆5与中心圆5连接的圆弧状凸起6共同组成凸轮3的主体结构，所述凸轮3通过旋转机构Ⅰ驱动转动，所述凸轮3的四周围绕凸轮3的转动中心设有至少一个成型机构，成型机构用于对扁线19进行弯折成型，所述成型机构的数量与圆弧状凸起6的数量一致，并且与圆弧状凸起6一一对应，所述成型机构包括与机架水平固定连接的支撑台14，所述支撑台14上竖直贯穿设有扁线孔15，需要弯折的扁线19从扁线孔15的下方穿过扁线孔15，所述扁线孔15位于中心圆5的半径延长线上，所述支撑台14上通过导向机构7滑动设有滑块8，所述滑块8位于凸轮3与扁线孔15之间，所述滑块8的移动方向位于凸轮3的转动中心与扁线孔15中心的连线上，所述滑块8的一端与凸轮3的侧壁抵接，所述滑块8的另一端与扁线孔15相对应，所述滑块8连接有弹性复位机构，所述支撑台14上设有抵挡块16，所述抵挡块16位于扁线孔15远离滑块8的一端。
将扁线19从下方穿过扁线孔15，然后凸轮3转动，滑块8的一端抵在凸轮3的侧壁上滑动，当滑块8经过圆弧状凸起6时，随着凸轮3的转动，会推动滑块8向外侧方向移动，滑块8的另一端经过扁线孔15将伸出的扁线19向外侧推动最终抵在挡块上，从而将扁线 19伸出扁线孔15的部分向外侧方向进行了折弯，最后当滑块8与凸轮3抵接的位置通过圆弧状凸起6后，挡块通过弹性复位机构驱动向内侧方向移动，使滑块8上远离凸轮3的一端回到扁线孔15的内侧方向，并使滑块8始终抵在凸轮3的侧壁上，完成一次折弯后，凸轮3再反向转动，进行下一次折弯，因此在凸轮3连续来回转动的过程中，间歇性的驱动滑块8相外侧移动，可以连续的进行扁线19的折弯。
优选的技术方案，所述滑块8的一端通过滚轮Ⅰ9与凸轮3的侧壁抵接，所述凸轮3Ⅰ侧立转动安装于滑块8上，所述滑块8的另一端转动安装有与扁线孔15相对应的滚轮Ⅱ10，所述滚轮Ⅱ10水平设置。
通过滚轮Ⅰ9与滚轮Ⅱ10的滚动设置能够避免滑块8与凸轮3侧壁以及与扁线19之间产生滑动摩擦，避免造成磨损。
优选的技术方案，多个圆弧状凸起6围绕凸轮3的转动中心等距分布，所述圆弧状凸起6与中心圆5侧壁的连接处圆弧过渡设置。
优选的技术方案，所述旋转机构Ⅰ包括旋转电机Ⅰ4，所述旋转电机Ⅰ4竖直设置于凸轮3的上方，所述旋转电机Ⅰ4安装于机架上，所述凸轮3的转动中心处固定连接有一竖直设置的连接轴，所述旋转电机Ⅰ4的输出轴朝下与连接轴固定连接，通过旋转电机Ⅰ4带动凸轮3进行转动。
优选的技术方案，所述导向机构7包括两根分别固定设于滑块8两侧的套管17，所述套管17水平设置，所述套管17的长度方向与 滑块8的移动方向相平行，所述套管17的外端面上超内延伸形成滑孔，所述滑孔内匹配滑动设有滑杆18，所述滑杆18的一端伸出套孔后与支撑台14固定连接。
通过套管17与滑杆18的导向作用，限制了滑块8的滑动方向。
优选的技术方案，所述弹性复位机构包括设于滑孔内的弹簧，所述弹簧的长度方向与滑杆18的长度方向一致，所述弹簧的一端与滑杆18连接，所述弹簧的另一端与滑孔的内壁连接，所述弹簧始终处于压缩状态。
由于弹簧始终处于压缩状态，因此弹簧始终存在推动滑块8相内侧移动的趋势，因此可以使滑块8的一端始终抵在凸轮3的侧壁上沿着凸轮3的侧壁进行移动。
优选的技术方案，所述抵挡块16包括相对设置的挡块Ⅰ11与挡块Ⅱ12，所述挡块Ⅰ11与挡块Ⅱ12同步相对或者相反移动，所述挡块Ⅰ11与挡块Ⅱ12的移动方向与滑块8的移动方向相垂直，所述挡块Ⅰ11与挡块Ⅱ12分别通过一安装于支撑台14上的推动气缸13驱动移动。
通过两个推动气缸13分别推动挡块Ⅰ11与挡块Ⅱ12相向运动，挡块Ⅰ11与挡块Ⅱ12合拢后共同形成抵挡。
