今天钣金加工厂的工作者给大家讲讲我国冲压技术的发展情况,如果你对这个信息感兴趣的话,欢迎咨询我们钣金加工厂哦。我们将竭诚为您服务。

好了,下面就来看看详细信息吧:

近十多年来,随着对发展先进制造技术的重要性获得前所未有的共识,冲压成形技术无论在深度和广度上都取得了前所未有的进展,其特征是与高新技术结合,在方法和体系上开始发生很大变化。计算机技术、信息技术、现代测控技术等冲压领域的渗透与交叉融合,推动了先进冲压成形技术的形成和发展。本文着重结合汽车工业的发展需求,讨论冲压技术的现状和发展趋势。

冲压技术的真正发展,始于汽车的工业化生产。20世纪初,美国福特汽车的工业化生产大大推动了冲术的研究和发展。研究工作基本上在板料成形技术和成形性两方面同时展开,关键问题是破裂、起皱与回弹,涉及可成形性预估、成形方法的创新,以及成形过程的分析与控制。但在20世纪的部分时间里,对冲压技术的掌握基本上是经验型的。分析工具是经典的成形力学理论,能求解的问题十分有限。研究的重点是板材冲压性能及成形力学,远不能满足汽车工业的需求。60年代是冲压技术发展的重要时期,各种新的成形技术相继出现。尤其是成形极限图(fld)的提出,推动了板材性能、成形理论、成形工艺和质量控制的协调发展,成为冲压技术发展史上的一个里程碑。由于80年代有限元方法及cad技术的先期发展,使90年代以数值模拟仿真为中心的和计算机应用技术在冲压领域得以迅速发展并走向实用化,成为材料变形行为研究和工艺过程设计的有力工具。汽车冲压技术真正进入了分析阶段,传统的板成形技术开始从经验走向科学化。

好了,今天关于钣金加工冲压技术的发展信息就讲到这了。

Today, the workers of the sheet metal processing plant tell you about the development of China's stamping technology. If you are interested in this information, welcome to consult our sheet metal processing plant. We will serve you wholeheartedly.

Well, let's take a look at the details.

In the past more than 10 years, with the unprecedented consensus on the importance of developing advanced manufacturing technology, the stamping forming technology has made unprecedented progress in both depth and breadth, which is characterized by the combination of high and new technology and great changes in methods and systems. The penetration and cross fusion of computer technology, information technology, modern measurement and control technology and other stamping fields have promoted the formation and development of advanced stamping technology. This paper focuses on the development trend of stamping technology combined with the development needs of the automotive industry.

The true development of stamping technology starts with the industrialized production of automobiles. In the early twentieth Century, the industrialized production of Ford automobile in the United States greatly promoted the research and development of Chong Shu. The research work is basically carried out at the same time in two aspects of sheet forming technology and formability, the key problems are rupture, wrinkling and rebound, involving the prediction of formability, the innovation of forming methods, and the analysis and control of the forming process. But in the part of twentieth Century, the mastery of stamping technology is basically experiential. The analysis tool is a classical theory of forming mechanics, and the problem can be solved very limited. The focus of the study is sheet stamping performance and forming mechanics, which is far from meeting the needs of the automotive industry. 60s is an important period in the development of stamping technology. Various new forming technologies have appeared one after another. In particular, the formulation of the forming limit diagram (FLD) has promoted the coordinated development of sheet performance, forming theory, forming process and quality control. It has become a milestone in the history of stamping technology. Due to the advanced development of the finite element method and CAD technology in 80s, the numerical simulation and computer application technology in 90s developed rapidly and became practical in the stamping field. It has become a powerful tool for the research of material deformation behavior and process design. The automobile stamping technology has really entered the analysis stage, and the traditional plate forming technology has begun to move from experience to scientization.

Well, today's information on the development of sheet metal stamping technology is here.
