支架冲孔落料冲压模具设计 摘 要 随着中国工业不断地发展，模具行业正在变得越来越重要了。本文针对支架弯曲件的冲裁工艺性，分析比较了成形过程中的三种不同冲压工艺（例如 单工序、复合工序与连续工序）确定用一幅级进模完成冲孔、落料工序的过程。本文介绍了支架弯曲件冷冲压的成形过程，经过对支架的批量生产、零件质量、零件结构以及使用要求的分析和研究，按照不降低使用性能为前提，将其确定为冲压件，用冷冲压方法完成零件的加工，并且简要分析了坯料形状、尺寸，以及排样、裁板方案，冲压工序的性质、数目和顺序等，并进行了冲裁力、压力中心、模具工作部分尺寸及公差的计算，并设计出模具的结构。同时具体分析了模具的主要零部件（如冲孔凸模、落料凸模、固定卸料装置、垫板、凸模固定板等）的设计与制造，冲压设备的选用，凸凹模间隙调整和编制一个重要零件的加工工艺过程。列出了模具所需零部件，并给出了合理的装配图。充分利用现代模具制造技术对传统机械零件进行了结构改进、优化设计、优化工艺方法，能大幅度提高生产效率，该方法对类似产品具有一定的借鉴作用。 关键词：固定卸料装置，级进模，冲孔落料 BRACKET PUNCHING AND BLANKINGDIE DESIGN ABSTRACT With the continuous development of Chinese industry, the mold industry is becoming more and more important. According to the blanking process of the stent bending, analyses and compares three different stamping process in the forming process (such as single processes, complex processes and continuous processes) to determine the process using a progressive die punching, blanking process completed. This paper introduces the frame bending forming process of cold stamping, batch production, parts of the stent, the parts of the structure and the quality of research and analysis of requirements, in line with lower performance prerequisite, which is identified as stamping parts processing, complete with cold stamping method, and a brief analysis of the blank shape, size, and layout, the conference board, stamping process nature, number and sequence, and the blanking force, center of pressure, the die size and the tolerance of the calculation, and designs the structure of die. At the same time, analyzes the mold of the main components (such as punch die, blanking punch discharging device, fixed fixing plate, plate, etc.) design and manufacturing, stamping equipment selection, machining process is an important part of punch and die gap adjustment and establishment. A list of desired mold parts, and gives a reasonable assembly. To make full use of the modern mold manufacturing technology were improved, optimizatio
