4、序（打印第一頁） 工藝清單 三、 總結(jié) 本課程及本次結(jié)課大作業(yè)后的感想及 收獲（可提建議）。設(shè)計(jì)內(nèi)容 一、設(shè)計(jì)任務(wù) 如圖1所示，設(shè)計(jì)所繪圖沖壓 頭凹凸模的實(shí)體模型并標(biāo)注尺寸；對(duì)沖壓頭凹凸模實(shí)體模型 進(jìn)行粗加工；對(duì)沖壓頭凹凸模實(shí)體模型進(jìn)行精加工；生成數(shù) 控加工代碼；生成工藝清單；加工仿真。其中R=24X10=240圖1沖壓頭模具零件圖 二、 建立實(shí) 體模型 建立的模具尺寸如圖 2、3。圖2模具尺寸圖 圖3模具尺寸圖 造型過程：1、繪制草圖0,正方形。如圖4。圖4建立正方形 2、拉伸增料，深度 16,如圖5、6。圖5拉伸增料對(duì)話框 圖6、拉伸增料實(shí)體 3、在拉伸實(shí) 體的一個(gè)表面繪制草圖1,并拉伸除

5、料，厚度 3.98,如圖7、 8。圖7拉伸除料對(duì)話框 圖8拉伸除料實(shí)體 說明為什么要 實(shí)體建模：實(shí)體造型的最顯著的特點(diǎn)就是說表示物體的完整性與無二 義性，也就是說實(shí)體造型不但能完整而且能唯一的確定地表 示物體，并且包含了完整的信息。它能夠更好的輔助機(jī)械制造，以保證所加工零件的精度要 求。所以要進(jìn)行實(shí)體的造型。三、加工過程設(shè)計(jì)定義毛坯：參照模型，基準(zhǔn)點(diǎn)為(-1000,-1000,0),大小為長(zhǎng)、寬、高 分另I為 2000, 2000,200其他參數(shù)如圖9。圖9定義毛坯對(duì)話框定義起始點(diǎn):坐標(biāo)為（0,0,100）,如圖10。圖10定義刀具起始點(diǎn)對(duì)話框定義刀具：初選使用兩把銃刀進(jìn)行加工。D11用于粗加

6、工，D10用于精加工。D11主要參數(shù)：銃刀，刀具半徑 80,刀角半徑0。D10主要參數(shù)：銃刀，刀具半徑 5,刀角半徑0.其他參數(shù)如圖11、12。圖11刀具D11定義對(duì)話框 圖12刀具D10定義對(duì)話框 粗加工軌跡生成1、對(duì)零件進(jìn)行粗加工，選用等高線粗加工。主要加工參數(shù)：加工參數(shù)1:加工方向：順銃，z切入層高3, xy切入行距40,切削模式環(huán)切，加工余量0.5,如圖13。圖13等高線粗加工加工參數(shù)1對(duì)話框 刀具參數(shù)：選用一D11。下刀方式：安全高度50,慢下刀距離10,退到距離10。如圖14。圖14等高線粗加工下刀方式對(duì)話框切削用量：主軸轉(zhuǎn)速1500,慢下刀速度100,切入切由連接速度 350,切

7、削速度600,退刀速度100,如圖15說明參數(shù)選取過程圖15等高線粗加工切削用量對(duì)話框 和依據(jù)：粗加工參數(shù)的選擇主要考慮切削的效率，選擇大半徑的銃刀便可以選擇大進(jìn)給量，選擇大背吃刀量。都可以節(jié)省切削的時(shí)間，也可以簡(jiǎn)化程序。初選銃刀半徑為80,為了使切削連貫進(jìn)給量應(yīng)小于銃刀直徑，選擇為40,又因?yàn)榇旨庸ぜ庸ぞ葹?0.1即可，采用順 銃方式精度更好一些，可以避免中間圓環(huán)部分切削不連貫。查資料可知，初加工背吃刀量不應(yīng)超過5,所以選擇3,以增加切削效率。加工余量設(shè)置為0.1。由于粗加工背吃刀量大，所以主軸應(yīng)輸由較大扭矩，選用較低轉(zhuǎn)速1500,切削速度都應(yīng)該選擇低速， 故選擇切入切由連接速度350,切

8、削速度600o下刀方式的設(shè)置是為了防止打刀。其他參數(shù)均采用默認(rèn)。求得刀具軌跡如圖圖 16、17。圖16粗加工刀具軌跡 圖17粗加工刀具軌跡 仿真加工 模型如圖18。圖18粗加工仿真加工模型 精加工軌跡生成：對(duì)零件進(jìn)行精加工，精加工方式選擇掃描線精加工。主要加工參數(shù):加工參數(shù)：加工方向往復(fù)，加工方法通常，xy方向行距2,加工順序區(qū)域優(yōu)先，加工精度為0.02,未精加工區(qū)不加工未精加工區(qū)域， 加工余量0。參數(shù)如圖19。圖19掃描線精加工加工參數(shù)對(duì)話框切削用量：主軸轉(zhuǎn)速3000,慢下刀速100,切入切由連接速度 800,切 削速度1000,退刀速度100,如圖20o圖20掃描線精加工切削用量對(duì)話框下刀

9、方式：安全高度50,慢下刀距離10,退到距離10,如圖21。圖21掃描線精加工下刀方式對(duì)話框刀具參數(shù)：選擇D10o其他參數(shù)均用默認(rèn)。說明參數(shù)選取過程和依據(jù)：精加工參數(shù)的選擇主要考慮零件的加工精度（形位誤差， 表面粗糙度）。所以應(yīng)選擇較高的切削速度，小的背吃刀量和進(jìn)給量。進(jìn)給量應(yīng)小于銃刀的直徑故選擇進(jìn)給量為2,背吃刀量選擇為0.5。這樣可以保證零件的加工精度。使用掃描線精加工可以保證零件的幾何精度o求得刀具軌跡如圖 22 o圖22精加工刀具軌跡 仿真加工模型如圖 23 o圖23精加工仿真加工模型四、生成數(shù)控加工代碼和工藝文件：車床選擇：機(jī)床選擇參數(shù)如圖 24。圖24機(jī)床選擇對(duì)話框 生成G代碼：(
