压缩机定子转子片冲压工艺及模具设计 摘 要 模具是大批量生产同型产品的工具，是工业生产的主要工艺装备。模具工业是国民经济的基础工业。 模具可保证冲压产品的尺寸精度，使产品质量稳定。而且在加工中不破坏产品表面。用模具生产零件可以采用冶金厂大量的廉价的轧制钢板或钢带为材料，而且在生产中不需要加热，具有生产效率高，质量好，重量轻，成本低节约能源和原材料等一系列的优点，是其他加工方法所不能比拟的。使用模具已经成为当代工业生产的重要手段和工艺发展方向。现代制造工业的发展和技术水平的提高，很大程度上取决于模具工业的发展。 多工位级进模是冲压模具中的一种，它是在单工序冲压模具基础上发展起来的多工序集成模具，在一副模具中可以完成冲裁，压弯，成型，拉伸等多种冲压工序，它可以将复杂的制件外形或型孔，经分解变成简单的冲压。因此，多工位级进模具有高效，高精度，长寿命的特点，它已成为实现大生产，降低生产成本的最佳选择。 关键词： 模具，冲压，级进模 The Stamping Process And Mold Design Of Stator And Rotor Piece Of Compressor ABSTRACT Molds to form a mass production of industrial production facilities, is the main techniques and equipment。Mold industry is the foundation of the national economy industry。 Tool to ensure accuracy of the ram of the product sizes, and make products quality。And the process of the surface of the product。Die in the production of parts of the metallurgical factory of rolled steel plates or with a material，And in production dont need, with high efficiency, quality, light weight and low cost to save energy and raw materials for a range of advantages，is Other process could compare with。Use of molds has become an important means of industry and technology development. modern industrial development and technical level, much depends on industrial development of the mold。 Many station level in the course of the machine mold is the ram, it is in the process of developing the stamp out the machine mold is up the process of integration mold，In a tool can be done to cut down, buckling, and stretch of the ram process, it can be a complicated system of a shape or size of holes and the dismantling of a simple press。Therefore, many station level of efficiency in the course, high precision, longevity, it has become the major production and reduce production cost of the best option.
