垫板零件的冲压工艺及模具设计

垫板零件的冲压工艺及模具设计摘要机械加工行业还在不断发展壮大，大众的生活越变越好，人们对于产品的生产生活要求越来越大，这就意味着已有的图章领域面临非常大的机遇与挑战。磨具分成塑料模具、五金模具和混凝土模具。在其中，木料公开赛彰显了非常重要的作用。大家日常生活里看到的诸多金属片和零件都可以用。此次的工件听说是通过直密封剂型侧板制作而成的。并没有弯折、拉深等其它多层结构。最重要的是要犒清楚工件的构造来确认适宜的模胚种类，比如复合模或冲压模具。最后设计方案应用盆栽花卉和强有力的紧密样子。下面，建立布局。版面图设计是工艺技术的前提。随后测算工件孔并选择适当的压力。然后将冲头、冲头、冲头和冲头切削刃的尺寸计算入立杆安装板。最终，将比赛融合为一个总体，利用CAD2D制作app比赛的总体构图法或半图，对命令进行筛选，编写最后汇总。关键词：冲孔：落料：垫板：CAD;复合模ABSTRACTThe mold industry is also developing and growing,people's lives are getting betterand better,and people's demand for production and life of products is increasing,whichmeans that the existing seal industry is facing huge opportunities and challenges.Themolds are divided into injection molds,stamping molds and concrete molds.Among them,the Timber Championships played a big role.Many metal plates and parts that we see inour daily life can be used.This time the workpiece is said to be made from a straight sealant-type backplane.There are no other special structures such as bending and deep drawing.It is important toanalyze the structure of the workpiece to determine the appropriate type of mold base,such as compound or progressive.The final design uses floral and punchy compact shapes.Next,create a layout diagram.Layout design is the foundation of stamp design.Thencalculate the workpiece hole and select the appropriate pressure.Finally calculate thedimensions of the punch,punch,punch and punch cutting edge into the column mountingplate.Finally,integrate the event as a whole,use CAD2D software to make the overallcomposition and half-map of the event,classify the instructions,and compile the finalsummaryKeywords:Guangdong Province;Cross border e-commerce;present situation;countermeasure目录目录1绪论1.1选题的意义与目的1.2文献综述1.3研究现状.21.4设计思路与创新思路2垫板的冲压工艺分析...32.1零件的材料分析32.2零件工艺分析42.3模具结构的初步确定..53垫板复合模的工艺计算….63.1f洋设计..…63.2中或力..73.2.1落料力83.2.2冲孔力3.2.3落料时的卸料力.83.2.4冲孔时的推件力..83.2.5冲床的总压力83.3压力机的确定.…..83.4压力中心的计算.93.5刃口尺寸计算….103.5.1冲孔刃口尺寸计算….113.5.2落料刃口尺寸计算.123.6本章小结..124复合模的零部件设计与选用222244444444444444444444444444444444444444a234.1模具主要零部件的设计134.1.1凹模的设计.134.1.2卸料板的设计144.1.3凸凹模的设计.154.1.4.凸模的设计...164.1.5其他零部件的设计174.2定位零件的设计…...184.2.1挡料销的设计184.2.2导料销的设计.194.3推件装置的设计…..194.4弹性元件的选用..204.5模架及其零件的设计.…214.6导柱、导套的选用…214.7上、下模座的选用.224.8模柄的选用..224.9螺钉、销钉的选用224.10模具的总体结构设计.224.11本章小结235总结24致谢..25参考文献26
