Abstract

本发明公开了一种用于大曲率铺放的碳纤维预浸料超短料程铺丝头，属于自动铺丝设备技术领域。它包括丝道主板，所述丝道主板包括第一槽口和第二槽口。它包括机架侧板，所述机架侧板的一端设为倾斜端，倾斜端上设有剪切组件，剪切组件包括气缸、剪切连接块、第一刀片和第二刀片；气缸的固定端倾斜固定在倾斜端上，气缸的活动端通过剪切连接块与第一刀片相连接，第一刀片的端部设有内凹型刃口；第二刀片设在第二槽口上，内凹型刃口的端部还倾斜设在第二刀片的下方，且第二刀片上的刀刃与内凹型刃口相配合，贴合的力由安装时的预紧力保证。本发明为保证在超短料程下，铺丝头头部各组件不与模具表面发生干涉，剪切组件的切丝方向与模具不垂直。在气缸伸长时带动第一刀片与内凹型刃口配合进行切丝，切丝完毕后气缸回收。
