舵基板双腔热压模具成型设计及工艺技术研究分析机电工程(专升本)专业摘要舵基板是某型号高硅氧纤维／钡酚醛树脂产品。产品长约为680毫米，宽度200毫米，外形尺寸大，形状复杂，迎风面的前端是圆锥面与斜平面相连接的头部突起，突起后部是为空气舵提供转动平台的平面。背风面是平面与弧面相连接的形状，套装时背风面与伺服舱相粘接，在产品后半部通孔是M120×1.5细牙螺纹结构。产品厚度差别大，最厚处27毫米，最薄处只有6毫米。产品成型时极易变形。舵基座板是空气舵系统的组件之一，是实现弹头机动飞行的重要防热部件，产品设计对舵基板产品的性能数值要求非常高。双腔热压模具采用不溢式“一模两件”的成型方式，及机械混料的方法，用模压成型工艺压制,成功应用于型号生产,效率较高，能够满足战术武器低成本、大批量生产要求。关键词：舵基板双腔热压模具螺纹镶块AbstractTherudderbaseplateisthevycorfibre/bariumBakeliteproductofsomemodelweapon.Theproductwhichhaslargeoutlinedimensionandcomplexshapehas680mmlengthand200mmwidth.Itsleadingendofwindwardsideisheadraisedthatjoinedwithtaperfaceandobliqueplane.Theendpartoftuberclesuppliesturningplaneforairrudder.Theleeface’sformisjoinedwithplaneandcamberedsurface.Whenshrinking,theleefacejoinswithservocabinandthebackhalfpartofproductisM120×1.5finethreadfabric.Theproducthaslargedifference,thebiggestthicknessis27mmandthelargestthinnessis6mm.Therudderbaseplateisoneunitoftheairruddersystem.Itisanimportantheatparttorealizebulletautomotiveflight.Theproductdesignhasahighrequirementfortherudderbaseplate’sperformance.Thepairhot-presseddieadoptsnonoverflowfamilymouldandmechanicalblendways.Itusesformerwindingtechnologytopressandsucceedinusingtomanufactureonemodelproduct.Ithashighefficiencyandcansatisfytacticalproductionrequirement.Keywords:Therudderbaseplate,Thepairhot-presseddie,screwglutting目录前言...................................................................1第一章舵基板成型工艺研究..............................................31.1舵基板使用工艺技术要求...........................................31.2舵基板成型工艺分析...............................................31.3热压模具的制造工艺分析...........................................51.3.1凸、凹模及螺纹镶件材料的选取.................................51.3.2凹模加工工艺.................................................51.3.3凸模加工工艺.................................................6第二章舵基板双腔热压模具成型设计......................................72.1舵基板双腔热压模设计中主要问题的考虑.............................72.1.1压模具固定方式...............................................72.1.2压模具加热方法的选取.........................................72.1.3热压模冷却方法的考虑.........................................82.1.4热压模具温度的测定...........................................92.2舵基板双腔热压模的设计形式.......................................92.3热压模凸、凹模的设计............................................112.4利用ANSYS软件对凹模进行受力分析................................122.5表面粗糙度的选取................................................152.6热压模具顶出机构的设计..........................................152.7模具复位机构的设计..............................................152.8模具加工制造中关键问题的解决....................................16第三章热压模具加热系统及监控装置.....................................183.1加热系统方案....................................................183.2监控装置................................................
