【正文】 g makes processing cost can fall to 40% 50%. The current module type stamping device integration is very high, in width is 300MM size range can arrange of 35 mold, through the roof top of stamping die for independent type series of control, is formed namely die of integrated control. The whole system programmable in WINDOWS user interface and menu under implementation, programming involves mould along the lateral positioning shaft servo drive positioning, strip inspection correction and longitudinal feeding positioning, stamping quality followup inspection, punching machine。 4. Stamping key parameters online adjust and pensation system, etc. Stamping process changes caused by workpiece quality is mainly caused by the wear of convex punching die, crack, dislocation, these small changes can be made of high resolution of a transfer sensor and rushed pressure turn sensor tracking detection. One extremely important displacement measurement is a kind of measure, this device, usually by installed in the mould, the GuanYuan and located below the receiving unit constitution, can monitor deviation, tracking processing process, timely output monitoring information and alarm downtime. An online stamping graphical processing system, is the effective guarantee stamping workpiece quality testing method, it can carry out 2d geometric figure of standard testing, the project has the length, diameter, parallelism, Angle, pressing plank structure and identification of waste, etc. Graphics processing system is by like meter, optical instrument and lighting equipment etc, the standard of CCD like instrument of bashan 750X580 bar lattice resolution for grid and jokshan horizontal direction for every sheshan lattice mm, vertical accuracy of fungi mm/sheshan lattice. Surveillance systems use the displacements and the Angle sensor are optical type and electrical type two kinds, the former has the laser testing technology and die like light sheshan technical support, The latter has a inductance and capacitance streaming media, they test accuracy resolution all may achieve the 110um grade level. The most suitable stamping technology transfer sensor installation plan is to put multiple turn sensor installed in a centralized sensor board, then put it precisely fixed in the mold outlet, namely the punch clamping board, using sensor data monitoring stamping process, and through the controller get timely treatment, guarantee the quality of the stamping. 汽車制造中沖壓工藝的新發(fā)展 汽車制造中有 60%70%的金屬零部件需經(jīng)塑性加工成形，沖壓加工是完成金屬塑性成形的一種重 要手段，它是最基本、最傳統(tǒng)、最重要的金屬加工方法之一。減少沖壓過程的工序數(shù)，意味著減少沖壓件數(shù)、節(jié)省工裝數(shù)量、簡化沖壓過程的傳送裝置，縮減操作人員和沖壓占地面積，是節(jié)約投資額和能耗的極好措施，所以沖壓制造商都能把沖壓工序數(shù)設(shè)計作為降低汽車制造成本的重要途徑，甚至不惜改進(jìn)產(chǎn)品設(shè)計來滿足制造工藝方面的要求。 現(xiàn)代沖壓成形發(fā)展和研究的重大課題包括有： （ 1）模塊式?jīng)_壓及其控制； （ 2）新材料及復(fù)合材料沖壓加工新工藝； （ 3）特種沖壓成形技術(shù)； （ 4）計算機(jī)模擬沖壓成形及虛擬試模技術(shù)； （ 5）模具制造技術(shù)； （ 6）沖壓成形過程自動監(jiān)控及失穩(wěn)機(jī)理分析等項(xiàng)。概括而言，模塊式?jīng)_壓的持點(diǎn)是： （ 1）在沖壓成形過程中可快速更換組合模具以提高生產(chǎn)效率； （ 2）由于具有帶材的供帶和矯帶裝置，可省卻另設(shè)上料下料工序； （ 3）實(shí)現(xiàn)了大工件的不停機(jī)加工； （ 4）既能獨(dú)立又能成系列的控制組合沖模動作，能連續(xù)進(jìn)行沖壓加工； （ 5）沖模具有可編和的柔性特點(diǎn)。 當(dāng)前模塊式?jīng)_壓裝置的集成度是很高的，在寬度為 300MM尺寸范圍內(nèi)可安排達(dá) 35個模具，通過沖模上端的頂板可對沖模進(jìn)行獨(dú)立式系列控制，即形 成沖模的集成控制。 亞毫米沖壓項(xiàng)目 亞毫米沖壓是指汽車車身沖壓件的精度控制在 ，與過去制造業(yè)通行的誤差2MM相比，是個非常大的 提高。 沖壓加工成形技術(shù)是影響汽車車身制造水平的關(guān)鍵因素之一，美國專家曾在一條汽車裝配線上對 50多個個案進(jìn)行實(shí)地分析表明，造成車身尺寸誤差變動的諸多原因中，沖壓件本身尺寸造成的積累誤差占 23%，其主要原因是傳統(tǒng)的基于經(jīng)驗(yàn)和原有工藝基礎(chǔ)上低水平上的模具設(shè)計與制造。 “ 2MM工程 ” 和 “ 亞毫米沖壓 ” 兩項(xiàng)目現(xiàn)已先后完成 ，正在美國三大汽車制造公司推廣應(yīng)用，取得了許多有益的成果，沖壓成本大幅下降，獲得日益增長的經(jīng)濟(jì)效益的社會效益，并逐步向其他國家推廣應(yīng)用。 現(xiàn)代汽車沖壓件的技術(shù)要求朝著結(jié)構(gòu)復(fù)雜、分塊尺寸增大、相關(guān)邊的零部件較多、承載能力變大和內(nèi)應(yīng)力限制嚴(yán)格等方向發(fā)展。介質(zhì)可以是無定形的固體、液體或氣體，在系統(tǒng)中介質(zhì)可依據(jù)要加工的形狀作任意變化，履行凸模功能，所以介質(zhì)可等同于一個萬能模具。電磁成形工藝原理圖，當(dāng)線圈通入 交流電時。 沖壓過程自動監(jiān)控 現(xiàn)代沖壓技術(shù)的另一個重要特點(diǎn)是對沖壓過程 進(jìn)行自動監(jiān)控以保護(hù)沖壓件的質(zhì)量。 一種在線沖壓的圖形處理系統(tǒng)，是保證沖壓工件質(zhì)量的有效測試方法，它能進(jìn)行二維幾何圖形的標(biāo)準(zhǔn)檢測，其項(xiàng)目有長度、直徑、平行度、角位、沖壓板材結(jié)構(gòu)及識別廢品等。
