1)零件图工艺分析 该零件表面由圆柱、圆锥、顺圆弧、逆圆弧及螺纹等表面组成。其中多个直径尺寸有较严的尺寸精度和表面粗糙度等要求;球面Sφ50㎜的尺寸公差还兼有控制该球面形状(线轮廓)误差的作用。尺寸标注完整,轮廓描述清楚。零件材料为45钢,无热处理和硬度要求。 通过上述分析,可采用以下几点工艺措施。 ①对图样上给定的几个精度要求较高的尺寸,因其公差数值较小,故编程时不必取平均值,而全部取其基本尺寸即可。 ②在轮廓曲线上,有三处为圆弧,其中两处为既过象限又改变进给方向的轮廓曲线,因此在加工时应进行机械间隙补偿,以保证轮廓曲线的准确性。 ③为便于装夹,坯件左端应预先车出夹持部分(双点画线部分),右端面也应先粗车出并钻好中心孔。毛坯选φ60㎜棒料。 (2)选择设备 根据被加工零件的外形和材料等条件,选用TND360数控车床。 (3)确定零件的定位基准和装夹方式 ①定位基准 确定坯料轴线和左端大端面(设计基准)为定位基准。 ②装夹方法 左端采用三爪自定心卡盘定心夹紧,右端采用活动顶尖支承的装夹方式。 (4)确定加工顺序及进给路线 加工顺序按由粗到精、由近到远(由右到左)的原则确定。即先从右到左进行粗车(留㎜精车余量),然后从右到左进行精车,最后车削螺纹。 TND360数控车床具有粗车循环和车螺纹循环功能,只要正确使用编程指令,机床数控系统就会自动确定其进给路线,因此,该零件的粗车循环和车螺纹循环不需要人为确定其进给路线(但精车的进给路线需要人为确定)。该零件从右到左沿零件表面轮廓精车进给,如图2所示。 图2 精车轮廓进给路线 (5)刀具选择 ①选用φ5㎜中心钻钻削中心孔。 ②粗车及平端面选用900硬质合金右偏刀,为防止副后刀面与工件轮廓干涉(可用作图法检验),副偏角不宜太小,选κ=35 0。 ③精车选用900硬质合金右偏刀,车螺纹选用硬质合金600外螺纹车刀,刀尖圆弧半径应小于轮廓最小圆角半径,取rε=~㎜。 将所选定的刀具参数填入数控加工刀具卡片中(见表1),以便编程和操作管理。 表1 数控加工刀具卡片 产品名称或代号 ××× 零件名称 典型轴 零件图号 ××× 序号 刀具号 刀具规格名称 数量 加工表面 备注 1 T01 φ5中心钻 1 钻φ5 mm中心孔 2 T02 硬质合金90 0 外圆车刀 1 车端面及粗车轮廓 右偏刀 2 T03 硬质合金90 0 外圆车刀 1 精车轮廓 右偏刀 3 T04 硬质合金60 0 外螺纹车刀 1 车螺纹 编制 ××× 审核 ××× 批准 ××× 共页 第页 (6)切削用量选择 ①背吃刀量的选择 轮廓粗车循环时选a p =3 ㎜,精车a p =㎜;螺纹粗车时选a p = ㎜,逐刀减少,精车a p =㎜。 ②主轴转速的选择 车直线和圆弧时,选粗车切削速度v c =90m/min、精车切削速度v c =120m/min,然后利用公式v c =πdn/1000计算主轴转速n(粗车直径D=60 ㎜,精车工件直径取平均值):粗车500r/min、精车1200 r/min。车螺纹时,参照式(5-1)计算主轴转速n =320 r/min. ③进给速度的选择 选择粗车、精车每转进给量,再根据加工的实际情况确定粗车每转进给量为㎜/r,精车每转进给量为㎜/r,最后根据公式v f = nf计算粗车、精车进给速度分别为200 ㎜ /min和180 ㎜/min。 综合前面分析的各项内容,并将其填入表2所示的数控加工工艺卡片。此表是编制加工程序的主要依据和操作人员配合数控程序进行数控加工的指导性文件。主要内容包括:工步顺序、工步内容、各工步所用的刀具及切削用量等。 表2 典型轴类零件数控加工工艺卡片 单位名称 ××× 产品名称或代号 零件名称 零件图号 ××× 典型轴 ××× 工序号 程序编号 夹具名称 使用设备 车间 001 ××× 三爪卡盘和活动顶尖 TND360数控车床 数控中心 工步号 工步内容 刀具号 刀具规格 / mm 主轴转速 / -1 进给速度 /mm. min -1 背吃刀量 / mm 备注 1 平端面 T02 25×25 500 手动 2 钻中心孔 T01 φ5 950 手动 3 粗车轮廓 T02 25×25 500 200

汽车挡泥板复合冲压模具设计 摘要:对汽车挡泥板进行冲裁工艺分析并确定冲裁方案,说明了模具主要零部件的设计和选用。以UG为平台,利用三 维参数化设计与建模技术,对汽车挡泥板的冲压模具进行三维参数化造型设计,可以根据需要改变模具的尺寸;进行虚 拟装配,可以直观地观察和分析模具的结构以及零件的相互位置关系;加快了产品开发速度,提高了产品开发效率,缩 短了产品开发周期。 关键词:UG;挡泥板;冲压模具设计 传统模具设计方法设计周期长、工作量大;在 整机装配环节,仅在理论上进行可行性的装配计算, 对于装配过程中可能出现的问题无法预知,各个零 件之间的相对装配关系只能间接表达出来,可视性 差;而且当某一个零件的参数改变时,整个设计过 程都要随之改变,设计智能化低。因此,利用高度 集成CAD/CAM功能的UG软件进行模具的三维造 型设计,通过对设计的三维模型进行分析和干涉检 查,根据得到的分析结果,可以确定是否修改现有 的装配模型,以达到修改设计的目的;并且可以利 用UG软件来实现参数化、智能化设计和虚拟装配, 使设计人员摆脱对物理样机的过度依赖,缩短产品 的设计开发周期,降低成本,提高产品质量,节省 人力物力。 1挡泥板落料冲孔模设计 (1)冲裁工艺分析及方案确定 该零件结构复杂,形状不对称,既有沟槽又有 悬臂,两处悬臂长小于5倍臂宽、宽度大于, 具体结构见图1。 工件材料为碳素结构钢08,厚度t=1 mm,采 用卷料,其抗剪切强度τ=255~353 MPa [1] 。材料具 有较高的弹性和良好的塑性,冲裁加工性较好。 该零件属于大批量生产,尺寸较大,形状不对 称且具有复杂的沟槽。经过分析,采用复合冲裁模 进行加工,能够满足各项要求。该复合模采用手工 送料、挡料销定位、弹压卸料,冲件由推件板推出, 模架为导面平稳的四导柱模架。 (2)排样设计 经分析,采用有搭边的直排,材料的利用率为 η=%,排样图见图2。 (3)冲压力计算 模具采用弹压卸料逆出件方式,故总冲压力为: Z Q 1 Q3 F =F +F +F(1) 式中:FZ为总的冲压力;F为冲裁力;FQ1为卸料力; FQ3为顶件力。 经计算FZ=353618 N,选择压力机型号J23- 63[2]。除此以外,还需正确确定其压力中心,以保 证冲压正常进行。 (4)凸、凹模刃口尺寸计算 该模具采用配作法计算凸、凹模刃口尺寸,以 冲孔凸模和落料凸模为基准件,凹模刃口尺寸按凸 模实际尺寸进行配作,保证单面间隙为 mm。 2主要零、部件的设计与选用 (1)凹模结构设计 由于该工件比较复杂,且有很深的沟槽,所以 将凹模设计为镶拼结构,并用内六角螺钉和销钉将 其固定在上模座上。凹模采用镶拼结构后,虽然拼 块的装配和模具结构变得复杂,但是分块后凹模易 于加工,精度容易保证,而且还可以将悬臂结构单 独作为一个部分,损坏后易于更换,可避免整体凹 模报废。凹模的具体结构见图3。 (2)凸凹模和冲孔凸模结构设计 凸凹模刃口部分为非圆形,为便于凸凹模和固 定板的加工,可设计成阶梯形结构,并将安装部分 设计成便于加工的长方形,通过铆接方式与固定板 固定。凸凹模的尺寸根据刃口尺寸、卸料装置和安 装固定要求确定,材料选用Cr12MoV,工作部分淬 火,硬度达到60~64 HRC。凸凹模具体结构见图4。 冲孔小凸模刃口为圆形,结构比较简单,材料 选用T10A。小凸模具体结构见图5。 (3)定位装置设计及模架选用 该模具主要采用接触定位,通过两个导料销和 一个挡料销来实现定位。由于工件轮廓复杂、冲裁 力较大且不均匀,故采用导面平稳的四导柱模架。 (4)其它零件设计 主要包括弹压卸料板、凸模固定板、垫板、推 件板、推杆、打板和打杆等,本文不做详细介绍。 3三维实体模型设计 利用UG做出挡泥板落料冲孔复合模的三维模 型,并进行虚拟装配,同时对其进行干涉检查。该 模具主要由以下部分组成:模柄、上模座、凹模、是轿门电机关门信号输出。PLC程序控制采用记录 开、关门一次反馈信号是否正确的方法进行判断, 如果输入信号有通有断,可认为没有发生短接、粘 连,系统正常工作,否则系统转入检修工作状态。 图5中M3的信号可作为门锁安全的正常信号,M4 是轿门或厅门线路断路、短路或输入信号线路断路、 短路或轿门与厅门安全线路中有一个短路、继电器 粘连等故障的信号,M5综合了M4的故障与将轿门 和厅门安全线路均短接、粘连或断线故障,可作为 控制系统由正常运行状态转为检修运行状态的触发 信号之一。 4结论 电梯门锁安全系统,在电梯的安全运行中起着 极其重要的作用。作为电梯设计、生产及安装改造 的人员和企业,应该本着以人为本、人文关怀的基 本思想,将人的生命放在第一位。在电梯的设计或 改造时,应充分考虑人员的安全,适当增加安全装 置和控制,使得在用电梯,即使是由于使用人员或 安装、维护人员的粗心或疏忽,也不会造成重大的 弹压卸料板、凸凹模、凸模固定板、下模座、导柱 导套等。装配爆炸图见图6。 4结论 本文以UG为设计平台,建立了汽车挡泥板复 合冲裁模的三维参数化模型,可根据需要改变模具 的尺寸,并且在虚拟装配过程中实时检查运动部件 间的干涉情况,修正模具零件、改进模具结构。通 过此种方法设计模具,大大加快了产品的开发速度, 明显缩短了开发周期。 参考文献: [1]钟毓斌.冲压工艺与模具设计[M].北京:机械工业出版社,2005.

模具毕业论文引言模具论文模具是一种技术密集、资金密集型产品,在我国国民经济巾的地位也非常重要。模具工业已被我国正式确定为基础产业,并在“十五”中列为重点扶持产业。由于新技术、新材料、新工艺的不断发展,促使模具技术不断进步,对人才的知识、能力、素质的要求也在不断提高。根据社会发展对模具专业学生的新要求以教学生的实际情况,探圳大学工程技术学院对99级模具设计方向学生的毕业设计的进行了较大的改节,并取得了较好的效果。2模具专业学生培养目标赣江学院模具设计与制造专业主要是从事注射模的设计与制造。为了明确本方向的培养目标,我们对江苏、浙江,特别是其周边地区模具企业进行了比较广泛的社会调查,调查结果表明,用人单位要求毕业生有较高的思想品质和道德修养,爱岗敬业和较好的与人协调共事能力,要求毕业生基础理论扎实,着重基本技能的掌握和再学习能力,要求毕业生熟练掌握外语,有一定的计算机软件应用和开发能力。根据调查结果分析,我们把模具专业人才培养的规格定位于:面向各类型企业,培养爱岗敬业,具备机械及各类模具设计与制造基础知识,具有较强的再学习能力和创造能力,能在模具生产第一线从事模具设计制造、技术开发、应用研究和经营销售的应用型工程技术和管理人才。据此把拓宽专业口径,课程体系合理,教学内容优化、实验研究能力强,社会适应面宽,作为本方向教学的基本指导思想,将模具设计理论、实践与及计算机应用融合为一体。3计算机技术在注射模中的应用领域塑料产品从设计到成型生产是一个十分复杂的过程,它包括塑料制品设计、模具结构设计、模具加工制造和塑件生产等几个工要方面。它需要产品设计师.模具设计师、模具加工工艺师及熟练操作工人协同努力来完成,它是一个设计、修改、再设计的反复迭代、不断优化的过程。传统的手工设计已越来越难以满足市场激烈竞争的需要。计算机技术的运用,正在各方面取代传统的手工设计方式,并取得了显著的经济效益。计算机技术在注射模中的应用主要表现在以下几个方面:(1)塑料制品的设计:基于特征的三维造型软件为设计者提供了方便的设计平台,而且制品的质量、体积等各种物理参数为后续的模具设计和分析打下了良妤的基础。(2)结构分析:利用有限元分析软件可以对制品的强度、应力等进行分析,改善制品的结构设计。(3)模具结构设计:根据塑料制品的形状、精度、大小、工艺要求和生产批量,模具设计软件会提供相应的设计步骤、参数选择.计算公式以及标准模架等,最后给出全套模几结构设计图。(4)模具开合模运动仿真:运用CAD技术可对模具开模、合模以及制品被推出的全过程进行仿真,从而检查出模具结构设计的不合理处,并及时更正,以减少修模时间。(5)注射过程数值分析:采用CAE方法可以模拟塑料熔体在模腔中的流动与保压过程,其结果对改进模具浇注系统及调整注塑工艺参数有着重要的指导意义,同时还可检验模具的刚度和强度、制品的翘曲性、模壁的冷却过程等。(6)数控加工:利用数控编程软件可模拟刀具在三维曲面上的实时加工过程并显示有关曲面的形状数据,同时还可自动生成数控线切割指令、曲面的三轴,五轴数控铣削刀具轨迹等。目前,国际上占主流地位的注射模CAD软件有Pro/E、I-DEAS、UGⅡ、SolidWorks等;结构分析软件有MSC、Analysis等;注射过程数值分析软件有MoldFlow等;数控加工软件有MasterCAM、Cimatron等。4模具专业毕业设计模式模具专业的学生要求综合知识和实践能力较强,它既是学生大学四年所学的机械制图、工程材料、公差配合与技术测量、塑料成型工艺与设备等技术基础课、专业课的综合应用,又需要学生了解大量的实践经验。通过毕业设计,应使学生在下述基本能力上得到培养和锻炼:①塑料制品的设计及成型工艺的选择;②一般塑料制品成型模具的设计能力;③塑料制品的质量分析及工艺改进、塑料模具结构改进设计的能力;④了解模具设计的常用商业软件以及同实际设计的结合,以往的毕业设计严格来说只能算是模具设计这门课的课程设计;老师指定一个塑料产品,有时甚至连产品模型图都交给学生,学生按照谍本上的模具设计步骤一步步做下去,由于没有实践经验,学校也不可能将学生的设计变成实际产品,因此,设计的合不合理,学生不知道,即使有经验的老师指不出不合理处,学生也没有感性认识,只能是纸上谈兵。学生踏人社会,从事实际产品设计,往往会发现无从下手,即使设计出来也是废纸一张,通常都要通过1到2年的时间才能入门。
