波纹管的成形工艺及模具设计

Forming technology and die design of ripple-shaped tube

分析了波纹管的成形工艺,并设计了相应的模具。详细介绍了模具的结构特点和工作过程。结果表明,利用模具,使波纹管在轴向挤压-高压内胀联合作用下一次成形。该工艺简单,质量可靠,效率高,取得了良好的经济效益。

In this paper, the forming technology was analyzed and die was designed of the ripple-shaped tube. This paper introduces its structural characteristic and working process in detail. The factual production indicates that the ripple-shaped tube can be once formed by axial extruding and high-pressure internal expanding based on die, which has simple process,reliable quality and high efficiency. Its economic benefit is excellent.
