【摘要】：从硬钎料的热挤压研究及应用现状谈起,分析了影响钎料热挤压的装备功能、模具性能和工艺因素(速度、温度、变形指数、模具形状)。结合生产实际阐述了常用的挤压装备、经典挤压工艺和主要的模具失效形式及其原因,并针对失效形式提出了提高挤压模具使用寿命、稳定产品质量、提高生产效率的多项技术措施;探讨了提高钎料热挤压质量和效率的技术途径。调查研究发现,优良的装备、适宜的工艺和合理的模具设计是热挤压顺利进行的根本保证;模具材料、模具制造工艺和使用制度决定着模具使用的稳定性。
[Abstract]:Based on the research and application of hard solder hot extrusion, this paper analyzes the equipment function, die properties and technological factors (speed, temperature, deformation index, die shape) which affect the hot extrusion of brazing filler metal. Combined with the production practice, the common extrusion equipment, classical extrusion process, main die failure forms and their causes are expounded. The service life of extrusion die is improved and the product quality is stabilized according to the failure form. Several technical measures to improve the production efficiency are discussed, and the technical ways to improve the quality and efficiency of hot extrusion of solder are discussed. It is found that excellent equipment, suitable technology and reasonable die design are the fundamental guarantee for the smooth progress of hot extrusion, and the stability of die use is determined by die material, die manufacturing technology and application system.
