【正文】 監(jiān)視系統(tǒng)使用的位移及角度傳感器有光學(xué)式及電學(xué)式二種，前者有激光測試技術(shù)和模似光珊技術(shù)支持；后者有電感流式及介質(zhì)電容式，它們的測試精度分辯率都可達(dá)到 110um級(jí) 的水平。 沖壓過程引起工件質(zhì)量發(fā)生變化的原因主要有凹凸沖模的磨損、裂紋及沖模錯(cuò)位等，這些微小變化可由高分辯率的位移轉(zhuǎn)感器和沖壓力轉(zhuǎn)感器進(jìn)行跟蹤檢測。當(dāng)線圈在工件內(nèi)時(shí)，電磁力將使工件外張成形，屬當(dāng)前應(yīng)用較廣泛的一種工藝；當(dāng)線圈平面平行于板件放置時(shí)，電磁力將使工件拉伸成形。 利用通電線圈產(chǎn)生的電磁力的電磁成形工藝，是目前頗有前途的另一種新型加工手段。限于本文篇幅，這里主要介紹內(nèi)壓成形和電磁成形兩項(xiàng)技術(shù)。這要求并促進(jìn)特種沖壓成形技術(shù)如液壓成形、精密成形、爆炸成形、旋壓成形、無模成形、激光成形和電磁成形技術(shù)的發(fā)展。敏捷度含義則是指減少?zèng)_壓件的生主準(zhǔn)備時(shí)間達(dá) 30%，包括模具設(shè)計(jì)、試樣制造和工裝準(zhǔn)備時(shí)間，以達(dá)到極大縮短新車型制造周期的目的，該項(xiàng)目飲食有沖壓和裝配的集成設(shè)計(jì)、沖壓系統(tǒng)敏捷設(shè)計(jì)和制造、沖壓過程的智能檢測和監(jiān)控、全系統(tǒng)集成4個(gè)子項(xiàng)目。該項(xiàng)目與 “ 2MM工程 ” 都是 90年代后期美國汽車界開展的大型研究項(xiàng)目。 當(dāng)沖模重新配置或更換時(shí)，這些變化則會(huì)被參數(shù)并被控制系統(tǒng)所貯存，以務(wù)下次查詢和調(diào)用。這種沖壓系統(tǒng)在運(yùn)行時(shí)可進(jìn)行沖模橫向位移、帶材進(jìn)給定位、沖模重復(fù)運(yùn)行及自動(dòng)調(diào)整下工步的沖模調(diào)整等多項(xiàng)功能。柔性的含義較廣，如沖壓件的幾何形狀的多種要求，只要 通過自由編程就可獲得，體現(xiàn)了加工形狀的柔性。空氣阻力減少，又可減少?zèng)_壓件數(shù)量及焊點(diǎn)，能有效地降低成本。 所謂沖壓工藝性是指沖壓件對(duì)工藝品的適應(yīng)性，即所設(shè)計(jì)的沖壓件在尺寸大小、尺寸精度與基準(zhǔn)、結(jié)構(gòu)形狀等是否符合沖壓加工的工藝要求。 (3) workpiece surface appearance only with pressure liquid contact, pressure is gentle, parts forming process changes, can obtain the symmetry of uniform pressure distribution, and can winner much better smooth outside surface, (4) in stamping and bloom some hydraulic tool charge can reduce 40%, special reduced convex parts processing of takt time is shorter, about MIN, this in special forming process is shorter, may realize the batch production. Using the electromagic force generated electricity coil electromagic forming process, is the present quite promising another new processing method. This process from 1960s nuclear fission research achievement, but unfortunately has not been people attention. Electromagic forming technology principle diagram, when the coil access to electricity. Few microseconds inside establish electromagic field, so the metal workpieces especially conductivity strong copper aluminum texture produce electric current, a current, induced current induced by magic force and effect, make the workpiece create tension and anastomosis and rapid forming. When the coil in the workpiece in electromagic force will make workpiece outside of the current application, zhang forming widespread a kind of technology, When the coil planar parallel to the board piece is placed, electromagic force will make workpiece stretch forming. Electromagic forming technology is a noncontact forming process, and its outstanding merits are shaping a rapid high efficiency, 2 it is often used in metal or nonmetal connection, can replace adhesive or welding, A third is not consumption lymphocy help materials such as lubricating grease, etc, the advantageous environment protection. Stamping process automatic monitoring Modern scramjet another important feature is for punching process automatic monitoring to protect the stamping quality. In the mm stamping project automatic detection and monitoring, its research results will include: 1. The stamping process characteristics of online preach diagnosis and detection system, 2. High speed and noncontact measuring system。 (2) due to its strip for belt and masking belt device, can save another set feeding blanking process, (3) achieved great work pieces the nonstop machining, (4) can both independent and can bee series of control bination dies action can continually stamping processing。 (3) special stamping technology。 Automobile manufacture stamping process of new development Automobile manufacture has a 6070% of metal parts must be approved by the plastic processing forming, stamping process is plete metal plastic forming a kind of important means, it is the most basic, the most traditional, the most important one of metal processing method. Such as vehicle body all kinds of covering parts, car support pieces, structure strengthen pieces, there39。 (4) puter simulation stamping mold testing technology。 (5) dies with programmable and the flexible characterist
