一、概述众所周知,研究锻模的中心是在确保按合理技术条件(如精度等)生产出合格锻件前提下,最大限度地提高锻模的寿命。重点放在寿命上的原因是:1.涉及模锻件成本8～12％的问题。2.涉及能否实现大量生产和自动化生产(模具寿命1～2万件)的问题。3.涉及能否满足锻件精化不断提高的问题。那么怎样才能提高模具寿命呢?这是学者和科技工作者多年来苦心钻研的课题。他们从锻模的工作特点、损坏机理和方式、锻模材料、制造手段、
I. Overview As we all know, the center of research forging die is to ensure that the reasonable conditions (such as accuracy, etc.) to produce qualified forging under the premise of maximizing the life of die. The reasons for focusing on life expectancy are: 1. Problems involving 8-12% cost of die forgings. 2. Concerned about the ability to achieve mass production and automated production (die life of 1 to 20,000) problem. 3. Involved can meet the continuous improvement of forging problems. So how can we improve the life of the mold? This is a subject that scholars and scientists work hard over the years. They work from the characteristics of forging, damage mechanisms and methods, forging materials, manufacturing tools,
