1、斜楔结构分析及支架冲压模具设计摘要:模具工业是国民经济的基础工业,是国际上公认的关键工业。模具成形具有效率高、质量好、节省原材料、产品成本低等优点,采用模具制造产品零件已成为当今工业生产的重要工艺手段。本设计详细的论述了冲压模具的详细过程,本文介绍的模具实例结构简单实用,使用方便可靠。本套模具的设计不是以复杂模具的设计为主,而主要是对模具设计知识的系统学习和设计的练习,以达到掌握冲压模具设计的基本技能的目的。首先,对零件做整体的分析。包括:材料的使用、精度的要求、工序的要求以及成本的要求等。为了降低成本,对排样方式进行了合理的设计;其次,对零件整体进行工艺设计。通过工艺目的的设计、工序的顺序设
2、计、压力机的选择等来实现所要达到的要求;再次,想要保证制件精度的要求,就要考虑模具刃口尺寸的计算。因为刃口是冲制工件的主要工作部分,刃口处的精度就决定了制件的精度,就必须根据公差来进行精确计算。最后,根据计算出的模具尺寸设计出相应的凸凹模,并且查找资料选择冷冲压模的标准零件,符合标准后,就把凸凹模与其它各零部件进行总体装配。在确定了模具体闭合高度后,选出合适的压力机在调试校验后并进行试冲加工,以达到符合的标准,最终完成链板片的加工。关键词:弯曲模,冲压工艺,模具设计Wedge structural analysis and stent stamping die designAbstract:M
3、ould industry is the basic industry of national economy, is internationally recognized as the key industry.Die forming with high efficiency, good quality, saving raw materials, lower the product cost,Parts adopt mould manufacturing products has become an important technology in todays industrial pro
4、duction means.This design is for the single-operation dies to the sheet metal,Examples in this paper, the mold structure is simple and practical,easy to use and reliable.This set of mold design is not given priority to complex mold design,the main is to mold design knowledge system study and design
5、practice,In order to achieve the purpose of the master the basic skills of stamping die design。 First,analysis of the parts to do the whole。Include:the use of material,the requirement of accuracy,the requirements of the process and cost requirements.In order to reduce costs, to design a reasonable l
6、ayout manner.Second, the whole process of parts design.Lsat,you want to ensure the parts accuracy requirements, it is necessary to consider the calculation mold edge size.Because the blade is the main working parts, punch the workpiece is decided by the precision of the edge of the precision of the
7、parts, must be accurately calculated according to the tolerance。 Finally,according to the calculated size of the mold design the appropriate punch and die,find information and choice of cold stamping die standard parts,comply with the standards,put the convex concave mold with various other componen
