齐齐哈尔大学毕业设计（论文)题目J23-40压力机曲柄滑块机构结构设计学院机电工程学院专业班级机械116班学生姓名周新指导教师刘尚成绩齐齐哈尔大学毕业设计（论文）年月日齐齐哈尔大学毕业设计（论文）摘要曲柄压力机广泛应用于冲裁，弯曲，校正，模具冲压等工作。本次设计的为J23-40型压力机曲柄滑块机构结构设计。此次设计由于分工不同，主要完成的是曲柄压力机曲柄滑块机构的设计。在设计中主要是根据总体设计确定的压力机主要参数，公称压力，滑块行程等参数参考相关手册初步估算曲柄，连杆，滑块，导轨相关尺寸，然后分别校核，修正，最终确定各零部件尺寸，并根据要求完成装模高度调节装置设计。最后写出详尽曲柄滑块机构设计说明书，绘出主要零件图。关键词：公称压力；曲轴；连杆；滑块I齐齐哈尔大学毕业设计（论文）AbstractCrankpressmachinewidelyusedinpunching,bending,correction,diestampingetc..ThedesignforthestructuredesignofslidercrankmechanismofJ23-40press.Thisdesignduetodifferentdivisionoflabor,mainlytocompletethedesignofthecrankpressslidercrankmechanism.Inthedesignismainlyaccordingtothepressofthekeyparameterstodeterminetheoveralldesign,thenominalpressure,slidestrokeparametersreferencemanualpreliminaryestimatesofcrank,connectingrod,aslideblock,railcorrelationdimension,thencheck,correction,andultimatelydeterminethesizeofpartsandcomponents,andaccordingtotherequiredtocompletediefillingheightadjustmentdevicedesign.Finally,writethedetaileddesignspecificationofslidercrankmechanism,figureoutmajorparts.Keywords:nominalpressure；crankshaft；connectingrod；sliderIII齐齐哈尔大学毕业设计（论文）目录摘要.............................................................................................................................IAbstract........................................................................................................................II第1章绪论.......................................................11.1研究背景....................................................11.2国内外研究现状..............................................11.3曲柄压力机的工作原理及主要参数..............................21.3.1曲柄压力机的工作原理...................................21.3.2曲柄压力机工作的特点...................................31.3.3J23-40型压力机主要参数................................31.4本章小结....................................................4第2章曲柄滑块机构的运动分析与受力分析.............................52.1曲柄滑块机构的运动规律......................................52.1.1滑块的位移和曲柄转角之间的关系.........................52.1.2滑块的速度和曲柄转角之间的关系.........................62.2曲柄滑块机构的受力分析......................................72.2.1忽略摩擦情况下滑块机构的力学分析.......................72.2.2考虑摩擦情况下滑块机构的力学分析.......................92.3本章小结...................................................11第3章曲轴轴系部件的设计计算......................................123.1曲柄形式...................................................123.1.1曲轴驱动的曲柄滑块机构................................123.1.2偏心轴驱动的曲柄滑块机构..............................133.1.3曲拐驱动的曲柄滑块机构................................133.1.4偏心齿轮驱动的曲柄滑块机构............................143.2曲轴的设计计算.............................................143.2.1曲轴材料的选定........................................143.2.2估算曲轴的相关尺寸....................................153.2.3曲轴的强度及刚度校核.................
