成型工藝分析墊圈的沖裁件產(chǎn)品見(jiàn)任務(wù)書(shū)所示，墊圈的技術(shù)要求為：材料為08鋼。厚度為t=10.15mm。外圈的直徑為25mm，內(nèi)孔的直徑為8mm，其余的尺寸按為注公差等級(jí)IT14設(shè)置。根據(jù)墊圈零件的結(jié)構(gòu)特點(diǎn)，零件的沖裁成型工藝包括沖孔和落料兩個(gè)基本工序，可以采用單工序形式，也可以采用復(fù)合工序的形式，以及連續(xù)模具的工序形式。具體的工藝方案如下：方案一：先落料，后沖孔，單工序模具結(jié)構(gòu)形式。方案二：落料和沖孔同時(shí)進(jìn)行。復(fù)合模具結(jié)構(gòu)形式。方案三：先沖孔、后落料的連續(xù)模具結(jié)構(gòu)形式。三種方案中，單工序模具結(jié)構(gòu)簡(jiǎn)單，工藝相對(duì)簡(jiǎn)單，制造成本低，易于加工和模具的維修，但需要使用兩幅模具，也適用于小批量或試制件生產(chǎn)。其中所需工藝力相對(duì)較小，易于保證零件的精度，單個(gè)模具的制造成本低，但會(huì)導(dǎo)致綜合工序的模具數(shù)量過(guò)多，生產(chǎn)分序過(guò)多而導(dǎo)致總成本增加，降低生產(chǎn)率。級(jí)進(jìn)模具（也叫連續(xù)模具）由多個(gè)工位組成，各工位按順序并聯(lián)完成不同的加工，在沖床上的一次行程中完成一系列的不同的沖壓加工，一次行程完成以后，由沖床送料機(jī)按照一個(gè)固定的步距將材料向前移動(dòng)，這樣在一副模具中就可以完成多個(gè)工序，具有很高的生產(chǎn)效率。同時(shí)，級(jí)進(jìn)模具操作安全，易于實(shí)現(xiàn)自動(dòng)化，減少?zèng)_床場(chǎng)地面積，減少半成品的運(yùn)輸和倉(cāng)庫(kù)占用等。復(fù)合模具可以把落料和沖孔兩個(gè)工序組合在一副模具上，一次性完成沖裁。但在模具零部件加工制造上比較的困難，成本較高。并且凹凸模容易受到最小壁厚的限制，而使得一些內(nèi)孔間距、內(nèi)孔與邊緣間距較小的下件不宜采用。根據(jù)墊圈的生產(chǎn)批量，材料的厚度，尺寸的精度要求等，選擇使用級(jí)進(jìn)模具比較的合理。其模具結(jié)構(gòu)成本都比較的合適，以墊圈級(jí)進(jìn)模具為載體的項(xiàng)目較為全面的將沖裁基礎(chǔ)知識(shí)進(jìn)行了應(yīng)用。合理的組合了項(xiàng)目理論知識(shí)并基于級(jí)進(jìn)模具的結(jié)構(gòu)，學(xué)習(xí)單工序的沖孔、落料模具知識(shí)。三、沖壓模具總體的相關(guān)設(shè)計(jì)1、排樣設(shè)計(jì)設(shè)在先沖孔后落料的級(jí)進(jìn)模具時(shí)，要先進(jìn)行條料的排樣圖設(shè)計(jì)。根據(jù)安裝板工件的結(jié)構(gòu)形狀，可采用下圖所示的排樣方法。由于08鋼為及軟的碳素鋼，強(qiáng)度、硬度很低。而韌性和塑性極高，但存在時(shí)效敏感性，淬硬性極低，同時(shí)考慮生產(chǎn)用原材料條料的取值特點(diǎn)：條料的寬度B=D+2a=（25+2x1.5）mm=28mm其中：B為條料寬度的基本尺寸；D為條料寬度方向零件輪廓的最大尺寸；a為側(cè)搭邊值，查表1-11搭邊最小值可得。模具的結(jié)構(gòu)采用有側(cè)壓裝置進(jìn)行送料，選取工件與條料之間的搭邊值為1.5mm，沖裁件之間的搭邊值為1mm（因?yàn)闆_小孔時(shí)，凸模易折斷，間隙應(yīng)取大值）。2、材料利用率=A/(BS)100%=60.5%其中：A為一個(gè)步距內(nèi)沖裁件的實(shí)際面積；S為送料步距（相鄰兩個(gè)沖裁件對(duì)應(yīng)點(diǎn)之間的距離）；B為條料的寬度。3、沖壓力的計(jì)算該模具采用級(jí)進(jìn)模具結(jié)構(gòu)，采用彈性卸料、打桿出件的結(jié)構(gòu)形式，沖裁力的相關(guān)計(jì)算如下：（1） 沖裁力：F=KLt=1.3（25+8）3.140.9360N43.6KNk為系數(shù)1.3；L為沖裁件的周邊長(zhǎng)度，即刃口周長(zhǎng)（mm）；t為材料的厚度；為材料的抗剪強(qiáng)度（MPa），查表1-1可得。（2） 卸料力：FX=KXF=0.0443.61.7KN（3） 推薦力：FT=KT F=0.0543.62.2KN（4） 頂件力：Fd=KdF=0.0643.62.6KN其中KX、KT、Kd表示系數(shù)，其值查表1-14可得。因?yàn)椴捎脧椥孕读涎b置和下出料方式，壓力機(jī)的公稱(chēng)壓力Fz=F+Fx+Ft=47.6KN.在上述計(jì)算中，沖裁力計(jì)算公式中的L值為落料周邊的刃口長(zhǎng)度與兩個(gè)沖孔刃口周邊的總和，同時(shí)依據(jù)計(jì)算出的沖裁力并結(jié)合模具結(jié)構(gòu)及外形尺寸，初選壓力機(jī)設(shè)備為J23-6.3。其主要工藝參數(shù)如下：最大壓力為63KN，滑塊行程35mm，最大閉合高度150mm，閉合高度調(diào)節(jié)量35mm，工作臺(tái)尺寸（前后左右）200mm310mm，模柄尺寸2540mm。壓力機(jī)的選擇依據(jù)模具課程設(shè)計(jì)指導(dǎo)P118-5.12冷沖壓成型常用設(shè)備選取。4、壓力中心的確定墊圈零件為對(duì)稱(chēng)性的規(guī)則形狀，其級(jí)進(jìn)模具中的刃口形狀，所以，模具的沖裁壓力中心與幾何中心重合。5、工作零件刃口尺寸的計(jì)算在進(jìn)行零件刃口計(jì)算之前，先要考慮工作零件的加工方法及模具的裝配方法。根據(jù)模具結(jié)構(gòu)及產(chǎn)品的生產(chǎn)情況，比較合適采用配合加工的制造方法，這樣易于保證沖裁的刃口間隙，降低制造成本，簡(jiǎn)化模具裝配工作，所以工作零件的刃口尺寸按照配合加工的方法進(jìn)行計(jì)算。安裝板級(jí)進(jìn)模具的刃口零件主要尺寸計(jì)算（單位：mm）如下：根據(jù)圖樣尺寸的精度和技術(shù)要求，因?yàn)閳D中未標(biāo)注尺寸公差，所以都選用IT14，查互換性與測(cè)量技術(shù)可得到以下結(jié)果：基本尺寸/mm標(biāo)準(zhǔn)公差等級(jí)IT6IT7大于至um61091518301321其中，凸模的設(shè)計(jì)按IT6，凹模的設(shè)計(jì)按IT7選用，零件的主要尺寸為：250.26mm，80.18mm。凹凸模刃口尺寸計(jì)算中X=0.5，因?yàn)闆_裁件的公差等級(jí)低于IT14或小批量生產(chǎn)時(shí)，取X=0.5。由于安裝板材料的塑性較大，材質(zhì)偏軟，結(jié)合經(jīng)驗(yàn)考慮，刃口間隙值取12.5%t=0.225mm，通常刃口間隙的經(jīng)驗(yàn)值取值范圍為（10%12.5%）t，該間隙查閱資料沖壓成型工藝與模具設(shè)計(jì)可得：當(dāng)t=0.9mm時(shí)，Zmax=0.126mm，Zmin=0.09mm，所以符合模具的設(shè)計(jì)要求。1) 對(duì)于落料的公稱(chēng)尺寸Dd=（Dmax-X）=（25.26-0.50.52）=25mm，上偏差為+0.021mm，下偏差為0；Dp=（Dd-Zmax）=（25-0.090）=24.91mm，上偏差為0，下偏差為-0.013mm。經(jīng)p+dZmax-Zmin校核，滿(mǎn)足模具的設(shè)計(jì)要求。2) 對(duì)于沖孔的公稱(chēng)尺寸dp=（dmin+X）=(7.92+0.50.36)=8mm;dd=（dp+Zmin）=（8+0.09）=8.09mm。經(jīng)p+dZmax-Zmin校核，滿(mǎn)足模具的設(shè)計(jì)要求。6、沖裁模具主要零部件的結(jié)構(gòu)設(shè)計(jì)工作零件的設(shè)計(jì)（1） 凸模結(jié)構(gòu)設(shè)計(jì)凸模的結(jié)構(gòu)設(shè)計(jì)形式主要由沖裁件的形狀、尺寸及加工工藝等條件決定，凸模刃口截面輪廓形狀通常為規(guī)則和不規(guī)則的，其結(jié)構(gòu)形式有整體式，鑲拼式，臺(tái)肩式，直通式和護(hù)套式等。由于凸模直接成型產(chǎn)品零件，所以凸模本身有較高的加工精度要求，其與固定板安裝通常采用H7/m6的過(guò)度配合或較小的間隙配合形式。1) 沖孔凸模（臺(tái)肩式凸模）h1=12為凸模固定板的厚度；h2=12為卸料板的厚度；h3=8為到料板的厚度；h=15為附加長(zhǎng)度，包括凸模的修磨量，凸模進(jìn)入凹模的深度及凸模固定板與卸料板間的安全距離，一般為1530mm。查閱相關(guān)資料可知：h1=（60%80%）H;h2=（80%100%）H;h3取68mm。H為凹模的設(shè)計(jì)。d=8mm；D1=d+（35）=12mm；D=D1+(35)=16mm。2) 落料凸模：d=25mm；D1=29mm；D=33mm。（2） 凹模結(jié)構(gòu)設(shè)計(jì)沖裁時(shí)凹模受沖裁力和側(cè)向擠壓力的作用，由于凹模各結(jié)構(gòu)形式的固定方法不同，受力情況又比較的復(fù)雜，目前還不能用理論方法確定凹模的輪廓尺寸。查表1-18（系數(shù)k值）可得：k=0.35mma、 凹模的厚度H（15mm）=kb1=250.35=8.75mm，所以H=15mm。其中b1為凹模寬度方向上刃口孔壁間的最大距離。b、 凹模寬度B的計(jì)算公式為B=b1+（2.54）H=25+315=70mmc、 凹模長(zhǎng)度L的計(jì)算公式為L(zhǎng)=L1+2C=34+222=78mm。其中L1為凹模長(zhǎng)度方向刃口孔壁間的最大間隙；C為凹模長(zhǎng)度方向上孔壁間與凹模邊緣最小，可查表1-19凹模孔壁至邊緣的距離得C=22mm。凹模結(jié)構(gòu)如下圖：(3)、擋料銷(xiāo)的設(shè)計(jì)擋料銷(xiāo)起定位作用，用它擋住搭邊或沖裁件輪廓以限定條料送進(jìn)距離。查表1-23（固定擋料銷(xiāo)）可得基本尺寸：7、設(shè)計(jì)和選用卸料板及卸料螺釘（1） 卸料板：卸料以卸料板卸料，固定卸料板的平面尺寸一般與凹模板相同，其厚度由上面的設(shè)計(jì)可得h2=12mm，固定卸料板的卸料力大，卸料可靠。根據(jù)以上信息可設(shè)計(jì)得出卸料板的結(jié)構(gòu)如下圖所示：（2） 卸料螺釘：選用45鋼，熱處理硬度HRC3540的圓柱內(nèi)六角卸料螺釘，卸料板上設(shè)置4個(gè)卸料螺釘，公稱(chēng)直徑為8mm，卸料釘尾部應(yīng)留有足夠的行程空間，卸料螺釘擰緊后應(yīng)使卸料板超出凹模端面1mm，有誤差時(shí)通過(guò)在螺釘與卸料板之間安裝墊片來(lái)調(diào)整。8、橡膠彈性元件的選用及計(jì)算橡膠的壓縮量不能過(guò)大，否則會(huì)影響其壓力和壽命。壓縮量L=L工作+L修磨mm=1+7mm=8mm。其中，L工作為卸料板的工作行程，L修磨為凸?？傂弈チ浚话闳?10mm。橡膠的厚度H=L/(0.250.3)mm=29mm。（取0.250.3得平均值0.275）9、選擇模架及其它模具零件（1） 選擇模架：根據(jù)GB/T2861.5-90，由凹模周界78mm70mm，厚度15mm，及安裝要求，選取凹模周界：LB=（8080）mm，閉合高度H=125mm145mm，上模座：（808030）mm，下模座：（808040）mm，導(dǎo)柱：（3280）mm，導(dǎo)套（324050）mm。由以上可得模架如下圖所示：（2） 模柄：由于壓力機(jī)的型號(hào)J23-6.3?？刹榈哪１椎闹睆綖?0，深度為55，根據(jù)裝配的要求，模柄與模柄孔的配合為H7/m6的過(guò)渡配合并加防轉(zhuǎn)銷(xiāo)釘，模柄長(zhǎng)度比模柄孔深度小510mm，由于采用固定卸料裝置，上模座回程時(shí)受力較大，因此選用壓入式模柄比較的合理，所以根據(jù)模具零件材料及熱處理的選用可查的模柄的結(jié)構(gòu)設(shè)計(jì)如下圖所示：（3） 墊板：墊板的作用是承受并擴(kuò)散凸模傳遞的壓力，以防止模座被擠壓損傷，因此在與模座接觸面之間加上一塊淬硬磨平的墊板。墊板的外形尺寸與凸模固定板相同，厚度可取310mm，此處設(shè)計(jì)選取規(guī)格為L(zhǎng)BH=78mm70mm8mm；（4） 凸模固定板：凸模固定板的外形尺寸與凸模的外形尺寸一致，厚度為12mm，選取的規(guī)格為L(zhǎng)BH=78mm70mm12mm。四、壓力機(jī)的校核（1） 公稱(chēng)壓力 根據(jù)公稱(chēng)壓力選取的壓力機(jī)型號(hào)為J23-6.3，它的壓力為 63KNFz=47.6KN.所以壓力得以校核；（2） 閉合高度 由于壓力機(jī)型號(hào)可得Hmax=150mm，M=35mm，H1=30mmHmin=Hmax-M=150mm-35mm=115mm。（M為閉合高度的調(diào)節(jié)量；H1為墊板的厚度，可查表開(kāi)式雙柱可傾壓力機(jī)技術(shù)規(guī)格得到）；根據(jù)GB/T 2851.3-90得模具的閉合高度為105mmH130mm，根據(jù)公稱(chēng)壓力選用的壓力機(jī)比和高度為115mmH150mm，H墊=30mm，因?yàn)镠min+10mmHHmax-5mm，即：125mm H 145mm，所以H=129mm，選預(yù)定壓力機(jī)J23-6.3符合要求。H=H上+H下+H凹+H凸+H墊-18=30mm+40mm+47mm+30mm-18=129mm。五、根據(jù)以上的設(shè)計(jì)分析，可以得出級(jí)進(jìn)模具的總裝配圖1、 內(nèi)六角螺釘 2、 墊板 3、圓柱銷(xiāo) 4、內(nèi)六角螺釘 5、下模座6、 橡膠7、圓柱銷(xiāo)8、卸料板9、凸模固定板10、上模座11、墊板12、落料凸模13、模柄14、打桿15、內(nèi)六角螺釘16、打料板17、沖孔凸模18、導(dǎo)套19、墊板20、凹模21、導(dǎo)柱總結(jié)項(xiàng)目化的教育給我最大的觸動(dòng)就是我能夠通過(guò)自己的努力去設(shè)計(jì)一套完整的工藝裝備。在這里，能夠找到自己的自信，同時(shí)，項(xiàng)目化的教育是一個(gè)很好的展現(xiàn)自我的平臺(tái)。針對(duì)本次的沖壓模具設(shè)計(jì)，我深刻體會(huì)到設(shè)計(jì)其中隱含的困惑與疑慮。而這些的問(wèn)題都要靠自己去查取相關(guān)的知識(shí)與理論，這不僅開(kāi)拓我的知識(shí)面，也增強(qiáng)了我的動(dòng)手能力和思維能力。圖表的識(shí)別是非常的重要，因?yàn)槠渲泻枚嗟牧悴考际菄?guó)家標(biāo)準(zhǔn)的，不需要過(guò)多的設(shè)計(jì)。這樣，自己的讀圖能力就必需要好。一分耕耘一分收獲，沒(méi)有徒勞而獲的好事。雖然說(shuō)本次的設(shè)計(jì)，每個(gè)人的數(shù)據(jù)都是大不相同的，但是方法都是類(lèi)似，結(jié)果的交流也是很有必要的。比如，當(dāng)某個(gè)設(shè)計(jì)步驟不太清楚地時(shí)候，組員之間可以相互的進(jìn)行溝通交流，或者通過(guò)對(duì)老師的咨詢(xún)來(lái)解決疑難問(wèn)題。讓自己能夠得到更好地發(fā)展。所以，學(xué)習(xí)，重要的是學(xué)習(xí)它的方式方法，懂得其中，鍛煉思維創(chuàng)新能力，而不是簡(jiǎn)單的照本宣科。對(duì)我來(lái)說(shuō)，設(shè)計(jì)是我很大的興趣。每當(dāng)通過(guò)一次的設(shè)計(jì)，我都能夠找到其中的設(shè)計(jì)，無(wú)形之中，計(jì)算、查閱、分析等等各方面的能力就得到了提升。此次的設(shè)計(jì)是我走向未來(lái)工作的重要一步，從最初的選題、開(kāi)題到計(jì)算、繪圖直到完成設(shè)計(jì)，期間查找資料、老師們的指導(dǎo)與同學(xué)的交流，每一個(gè)過(guò)程都是對(duì)自己能力的一次檢驗(yàn)和充實(shí)。不但使我更進(jìn)一步理解和懂得了以前學(xué)到的知識(shí)而且還把以前課本上學(xué)到的知識(shí)連接在了一起。使我能更好的融會(huì)貫通。相信在今后的設(shè)計(jì)中能夠更好地展現(xiàn)自己的才華。參考文獻(xiàn)1
