但是现有滚花装置不便于对顶头进行连续滚花，在拆卸和安装顶头时会浪费一定的时间，影响其工作效率，且顶头滚花时没有对其进行防护，挤压滚花时会带来一些危险，为此我们提出了一种无缝钢管穿孔机顶头滚花装置

Benefits of technology

[0010] The advantages of this utility model are: (1) In this utility model, the brake motor drives the turntable to rotate intermittently, and the turntable drives two sets of deceleration motors, clamps, and push rods to rotate intermittently. When one push rod moves to the side of the protective box, a top post is installed on the push rod. At this time, the other top post that moves to the inner cavity of the annular protective groove is knurled by a knurling knife. After the knurling operation, the knurled top post is moved to the side of the protective box and removed. Other push rods are installed on the push rod, and the top post on the other push rod is moved to the inner cavity of the annular protective groove for knurling. This realizes the function of continuous knurling and ensures the efficiency of knurling.
