【正文】 需要在國標(biāo)中選取標(biāo)準(zhǔn)的墊板型號(hào)。材料選用45鋼，熱處理的淬火硬度為48 ～ 52HRC， 以下。由于其結(jié)構(gòu)不同，功能也不一樣，固定卸料裝置就是起卸料作用；彈壓卸料裝置不僅沖壓完后起卸料作用，沖壓開始前還起壓料作用，防止沖壓過程中材料的滑移或扭曲，同時(shí)對(duì)銷凸模還有導(dǎo)向保護(hù)等作用，因此，模具的精度和使用壽命與卸料裝置的結(jié)構(gòu)、精度和強(qiáng)度有著直接的關(guān)系。2 。 凹模固定板 以上的公稱壓力計(jì)算，綜合考慮其他因素，選擇壓力J31400A機(jī). 壓力機(jī)參數(shù)型號(hào)J31400A主電動(dòng)機(jī)公率40KW公稱壓力4000 KN滑塊行程315mm行程次數(shù)20/min）最大裝模高度550mm最大閉合高度710mm工作臺(tái)尺寸1200﹡1250mm②它與壓力機(jī)的配合應(yīng)該遵守下列關(guān)系(HmaxHd)5H(HminHd)+105505H390+10545H400此設(shè)計(jì)中模具的閉合高度為407mm，滿足要求 模具工作過程即凸模在最高點(diǎn)時(shí)此時(shí)放入板料， 凸模往下滑動(dòng)與凹模作用形成制件。卸料板在橡膠螺柱的作用下將箍在凸模外的制件卸下。操作者將制件清除。 第5章 模具零件設(shè)計(jì) 模架結(jié)構(gòu)的選擇考慮到制件的精度及壓力機(jī)的最大裝模高度和滑塊行程確定模具閉合高度為407mm.,選擇對(duì)角導(dǎo)柱的模架。 上模座結(jié)構(gòu)根據(jù)模具閉合高度、滑塊行程上下模座的參數(shù)得標(biāo)準(zhǔn)號(hào)為：BG/T 主參數(shù)為：d=55 L=320。 各種版厚的確定根據(jù)模具的閉合高度、上下模座的厚度和凹模板的厚度綜合考慮各種因素確定凸模固定板、凹模固定板厚度。ha =40mm 凸模墊板厚度的確定，一般選取hb=10mm外形與與凹模外形尺寸一致。 加工凹模固定板工藝產(chǎn)品型號(hào)零件號(hào)零件名稱臺(tái)件材料牌號(hào)備料規(guī)格每毛坯重量材料消耗定額毛坯種類凹模固定板45鋼車間名稱共序號(hào)工序名稱及內(nèi)容一次加工數(shù)機(jī)床名稱編號(hào)工具名稱刀具夾具量具1下料Ф509X72氣割2畫線6XФ15 6XФ32鉗工3鉆孔4XФ15 6XФ32鉆床4淬火HRC5458熱處理車間5磨上下平面至25磨床擬定者日期工人代表日期標(biāo)記更改原因及內(nèi)容更改者日期 。 凹模加工工藝產(chǎn)品型號(hào)零件號(hào)零件名稱臺(tái)件材料牌號(hào)備料規(guī)格每毛坯重量材料消耗定額毛坯種類凹模T10A車間名稱共序號(hào)工序名稱及內(nèi)容一次加工數(shù)機(jī)床名稱編號(hào)工具名稱刀具夾具量具1氣割2線切割加工工作部分尺寸至要求線切割3畫線6XФ12 6 XФ33鉗工4鉆孔6XФ12 6 XФ33 鉆床熱處理車間5淬火HRC60646磨上下平面至63磨床擬定者日期工人代表日期審核者日期標(biāo)記更改原因及內(nèi)容更改者日期 彈性卸料版。產(chǎn)品型號(hào)零件號(hào)零件名稱材料牌號(hào)備料規(guī)格每毛坯重量材料消耗定額毛坯種類凸模固定板T10A車間名稱共序號(hào)工序名稱及內(nèi)容機(jī)床名稱編號(hào)工具名稱刀具夾具量具1氣割2畫線6XΦ14 6XΦ12鉗工3鉆孔6XΦ14 6XΦ12鉆床熱處理4淬火HRC54585磨上下平面40磨床日期工人代表日期審核者日期批準(zhǔn)者標(biāo)記更改原因及內(nèi)容更改者。 下模座板加工工藝產(chǎn)品型號(hào)零件號(hào)零件名稱材料牌號(hào)備料規(guī)格每毛坯重量材料消耗定額毛坯種類下模座板HT200車間名稱共序號(hào)工序名稱及內(nèi)容機(jī)床名稱編號(hào)工具名稱刀具夾具量具1下料B=568mmL=810mmh2=75mm采購2畫線2XФ556XΦ736XФ22Φ71Ф73鉗工3加工2XФ606XΦ306XФ12鉆床日期工人代表日期審核者日期批準(zhǔn)者標(biāo)記更改原因及內(nèi)容更改者。在這兩年里我系統(tǒng)的學(xué)習(xí)了機(jī)械方面的基礎(chǔ)知識(shí)。在畢業(yè)之際，我要感謝那些幫助我的老師及同學(xué)。在期間，從設(shè)計(jì)選題及設(shè)計(jì)，審核圖紙等環(huán)節(jié)，自始至終都傾注了老師們的心血，老師深邃的學(xué)科洞察力、淵博的學(xué)識(shí)、平易近人的作風(fēng)、嚴(yán)謹(jǐn)求實(shí)的態(tài)度、創(chuàng)造性的學(xué)術(shù)意識(shí)、崇高的道德修養(yǎng)、兢兢業(yè)業(yè)的敬業(yè)作風(fēng)、一絲不茍的科學(xué)精神和對(duì)學(xué)生啟發(fā)式和全面型的培養(yǎng)方式，都給我留下了終生難忘的印象，在潛移默化中培養(yǎng)了我不斷奮發(fā)向上、刻苦鉆研的精神和真誠待人接物的優(yōu)良品質(zhì)，并將最終使我受益終生。再一次非常感謝的領(lǐng)導(dǎo)，老師以及與我一起討論的各位同學(xué)對(duì)我的關(guān)心和幫助，我才能夠完成我的畢業(yè)設(shè)計(jì)。s how it works, directly or asked to die on the fixed on the position of the mold on the module, it handles through the mode of association with the press slider. Fixed on the next module is posed of the dieunder, and use clips fixed at the press table. Onandunder through I. I. oriented. Work, of the material sent to rely on positioning block material, when the module with the slider down, unloading first壓住sheet, and then convexconcave with access to the material above the workpiece. At this time the workpiece in the punch card and heard the top of the block, waste is also firmly behind the punch on. In the pickup mode, the workpiece by block through the roof top of the stretch from spring to die from the hole in the roof at the same time behind the punch on the waste discharge by the board on the elastic Xiediao spring, and then took part, this Blanking plete the whole process. Of the material sent to a further step, the next blanking blanking process, so a reciprocating. Second, the classification Die 1, open mode: simple structure, small size, light weight, easy to manufacture, low cost, but low life expectancy, poor accuracy, suitable for precision Yaoqiubugao, the beginning of simple, lowvolume or blanking of the trial production. 2, I. Plate: accuracy than the openhigh, suitable for simple beginning, not the size of the workpiece blanking pieces. Request not more than press tour guide plate thickness. 3, I. Column: I. blanking spaceoriented guarantee uniform, blanking of the workpiece size highprecision molds long life, easy installation, suitable for mass production. 4, Die: of the material requirements of precise positioning, and shape each other in the hole location accuracy is assured. High productivity, has a punching accuracy, suitable for mass production. 5, pound die: punching in the shape of the mutual position of high accuracy, suitable for mass production.Punching the material properties of materials First, when punching materials separation process can be divided into three stages: 1 elastic deformation stages: Gang Jiechu sheet metal punch the initial stage, in elastic deformation. 2 plastic deformation stages: Punch increasing downward pressure on, until a change in plastic microcracks. 3 fracture separation stages: to punch down, the pressure increased, microcrack growth. Coincidence, fracture, blanking of gradually declining. Elastic deformation stages: punching power gradually increased. Plastic deformation stages: punching power reached its peak. Features section features stage In the first stage of sheet metal punch under pressure. First of all produce flexible pression, tensile, such as deformation, then punch a little squeeze into the sheet metal, sheet metal on the other side has a slight edge squeeze into the die, the punch Below the Department of slightly bending the material, die on the edge of the above material began Shangqiao, the greater the gap, bending and Shangqiao more serious, in the convex sheet metal, die cutting edge angle formed the initial collapse, then the internal material Stress has not been more than elastic limit, when the external force can be removed after the material restitution. This phase known as the elastic deformation stage.
