拉延筋/摩擦试验机测控系统设计与实践

Practice & design on measure and control system of drawbead/friction simulator

随着汽车工业的迅猛发展 ,冲压制件的复杂程度和难度不断增加 ,拉延筋的设计选择已经成为冲压模具设计中的关键技术。本文介绍了拉延筋 /摩擦试验的原理和方法 ,针对上海宝钢从国外引进的拉延筋 /摩擦试验机在测控等方面的不足 ,提出了一套切实可行的改进设计方案 ,并成功的得到了实现。使试验机在试验参数的控制功能方面得到了改进和提高 ,并具备了高温拉延试验功能。为进行规范、统一的拉延筋 /摩擦试验提供了可靠的保证。

With the great development of the car industry, the complexity and the difficulty improved in the process of sheet forming The design of drawbead has been the sticking point of the design of punch die The article recommends the theory and method of drawbead/friction testing Aiming at the limitation of drawbead simulator imported by Shanghai Baosteel, we moved a more practical design program and made a successful test As a result, the simulator improved its control ability in testing parameter and possessed the capability of high temperature drawbead testing It provides a reliable assurance for a normative and unitive drawbead/friction testing
