提出了全锥面翻领成型器的基本思想，分析了其优缺点，并对其数学模型进行了详细研究，包括领口交接曲线、肩曲面、边界曲线。在计算机上对所建模型进行了Pro/E三维仿真验证。为正确设计圆形管全锥面翻领成型器提供理论依据。

The idea of full-cone shoulder former was put forward. Its advantages and disadvantages were analyzed. Its mathematical models were particularly studied including intersection curve, shoulder surface and fringe curve. The established mathematical models were validated by Pro/E software on computer. The purpose was to provide theoretical basis to make correct design of full-cone shoulder former of round tube section.
