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。
本设计进行了冲孔、落料复合模的设计。文中简要概述了冲压模具目前的发展状况和趋势。对产品进行了详细工艺分析和工艺方案的确定。进行了凹、凸模的闭合高度的计算并确定了模具的结构。计算并设计了本套模具上的主要零部件,如:凸模、凹模、凸凹模、凸模固定板、垫板、凹模固定板、卸料板、导板、挡料销等。选定了合理的冲压设备。设计中对工作零件和压力机规格均进行了必要的校核计算。此外,本模具采用挡料销挡料。模具的冲孔和落料凸模用固定板固定,便于调整间隙。

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 don't 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.
This design has been blanking, punching, progressive die design. This paper briefly outlines the current development of stamping die situation and trends. Carried out a detailed process of product analysis and identification technology program. Stamping die design in accordance with the general steps to calculate and design the mold of this set of key components, such as: punch, die, punch retainers, plate, fixed die plate, stripper plate, guide plate, block material or marketing. Mold using standard mold, use a suitable stamping device. Design specifications of the working parts and the press were carried out the necessary checking calculation. In addition, the mold used beginning with the gauge pin gauge. Die punching and blanking punch were fixed with different fixation plate, easy to adjust the gap; punching die is fixed by the overall fixed plate.
Key words: Gang dies; punch; die; Blanking
