《钢的冷挤压基础知识》是应本刊的要求,用讲座的形式,简单系统地介绍钢的冷挤压一些基本知识。目的是为了配合各工厂企业开展少无切削新工艺时,应用这一较为先进的压力加工方法。钢或有色金属的冷挤压,目前在国内已经有相当多的工厂大量采用了,取得了相当可观的政治经济效果,而且也积累了极其丰富的经验,这些经验对于推动我国冷挤压技术的普及以及在此基础上向更高阶段发展,无论就工艺或是设备方面都是宝贵的。这里重点介绍钢的冷挤压,因此对于有色金属的冷挤压就不准备涉及,关于其它的挤压方法,如中温挤压、水静挤压等,准备在最后简单叙述一下工艺及设备的特点。《钢的冷挤压基础知识》所介绍的主要内容: 1.钢的冷挤压概念及基本知识2.钢的冷挤压材料选择、毛坯制备及软化处理3.钢的冷挤压毛坯表面磷化处理及其润滑4.钢的冷挤压力5.钢的冷挤压件的工艺设计6.钢的冷挤压模具7.典型冷挤压件及模具8.钢的冷挤压设备9.钢的冷挤压进展 “The basic knowledge of cold extrusion of steel” is based on the requirements of this publication, in the form of lectures, a brief and systematic introduction of some basic knowledge of cold extrusion of steel. The purpose is to cooperate with the factories and enterprises to carry out less no cutting new technology, the application of this more advanced pressure processing methods. Cold extrusion of steel or non-ferrous metals, a large number of factories have been widely used in China at present, has achieved considerable political and economic results, but also accumulated extremely rich experience, these experiences to promote China’s cold extrusion technology Popularization and development on this basis to a higher stage are valuable both in terms of craftsmanship and equipment. The emphasis here is on the cold extrusion of steel, so cold extrusion of non-ferrous metals is not intended to be covered. For other extrusion methods such as medium temperature extrusion, hydrostatic extrusion, etc., a brief description of the process and equipment Features. The main contents of the “cold extrusion of steel”: 1. Cold extrusion of steel concepts and basic knowledge 2. Cold extrusion of steel material selection, blank preparation and softening 3. Cold extrusion of steel rough surface Phosphating and lubrication 4. Cold extrusion of steel 5. Steel cold extrusion process design 6. Steel cold extrusion die 7. Typical cold extrusion and die 8. Steel cold extrusion equipment 9. Steel cold extrusion progress
