弯头推挤加工法,因具有热冲压弯头无法比拟的独特优点,已成为目前最先进的急弯头制造工艺。我们在成功地实施弯头推挤新工艺的基础上,开展一些弯头推挤变形的试验研究工作。对推挤弯头的变形过程、变形规律及变形温度条件等有一定认识,本文仅从实践角度做初步探讨。 Elbow push processing method, because of the unique advantages of hot stamping elbow, has become the most advanced elbow manufacturing process. Based on the successful implementation of the new technology of elbow pushing, we carried out some experimental research on the elbow pushing deformation. There is a certain understanding on the deformation process, deformation rules and deformation temperature conditions of elbow bend. This article only makes a preliminary study from the practical point of view.
