本发明所述的一种片材切割高效裁切机，能够很方便的自动更换刀模，节约手动调试时间，提高了工作效率；在更换刀模的时候，片材被压住不松开，换刀模后能够再次冲切剩余的边角料，充分利用材料，无需再次装夹，节约材料，节省了时间；冲切头1可任意旋转角度，能够从各种角度冲切材料，使用范围广；刀库28改变位置，将原来与机架平行设置改为垂直设置，结构科学合理，更换刀模的时候，刀模移动距离短，定位更加精确，另外换刀模机构采用伺服滚珠丝杆传动，传动定位精确，受力更加科学合理，延长了使用寿命；换刀模机构采用无杆气缸，使整机结构更加紧凑，减少占地使用面积，使操作更加方便；本发明通过改变结构，故障率低，运行更加流畅，工作效率高，得到了客户的一致好评。
本发明所述支架27上方设有加强块38，所述加强块38连接机架3，增加刀库的稳定性，保证精度，延长使用寿命。
本发明所述连接框37上设有限位块39，限制刀模在移动过程中的位置，确保刀模定位准确。
本发明方案所公开的技术手段不仅限于上述实施方式所公开的技术手段，还包括由以上技术特征任意组合所组成的技术方案。
