摘 要

“自動(dòng)線落料翻轉(zhuǎn)設(shè)備” 是汽車覆蓋件自動(dòng)化沖壓生產(chǎn)線上的重要設(shè)備。其主要功能是承接機(jī)器人搬運(yùn)的板料，吸附并翻轉(zhuǎn)，整齊放置于料盤中。汽車覆蓋件的結(jié)構(gòu)特點(diǎn)有：尺寸大、板材薄、形狀復(fù)雜等；質(zhì)量特點(diǎn)有：尺寸精度高、表面精度嚴(yán)、結(jié)構(gòu)剛性強(qiáng)、加工工藝好等特點(diǎn)。隨著技術(shù)發(fā)展的進(jìn)程，眾多企業(yè)已經(jīng)或?qū)⒁讶斯ど舷铝系牧魉€改造為半自動(dòng)沖壓線和自動(dòng)沖壓線。
九十年代國(guó)內(nèi)首次自主研制開發(fā)的第一條轎車大型覆蓋件沖壓連線自動(dòng)化系統(tǒng)，性能穩(wěn)定可靠，運(yùn)行情況良好，操作簡(jiǎn)便。但是大型多工位壓力機(jī)自動(dòng)沖壓生產(chǎn)線由于造價(jià)昂貴及技術(shù)方面的問題，在國(guó)內(nèi)推廣使用尚待時(shí)日。
為此，我們將采用較為簡(jiǎn)單的氣動(dòng)和機(jī)械機(jī)構(gòu)，使用壓力機(jī)的自動(dòng)化氣源（由壓力機(jī)發(fā)出電子信號(hào)控制），實(shí)現(xiàn)落料零件的在線翻轉(zhuǎn)，該裝置有結(jié)構(gòu)簡(jiǎn)單、運(yùn)行可靠、使用維護(hù)方便等特點(diǎn)。
整個(gè)設(shè)計(jì)過程包括方案的選擇、在示意圖原理基礎(chǔ)上進(jìn)行詳細(xì)的設(shè)計(jì)、分析和計(jì)算，得出符合使用要求的裝置。

ABSTRACT

"Auto Line blanking flip equipment" is the auto cover automated production line punching the important equipment. Main function is to undertake the robot handling sheet metal, Adsorption and overturned, Neatly placed on the material after. Auto cover the structural features are: large size, thin sheet metal, the complex shape; The quality of the characteristics are: the size of high-precision, high-precision surface-rigid structure, good processing techniques, and so on. With technological development, more enterprises have been or should be expected from top to bottom of the pipeline into a semi-automatic and automatic stamping line stamping line.
In the'90s, the first time independent research and development of the first large-scale coverage of the cars stamping line automation systems, stable and reliable performance, good performance, simple operation. However, large-scale multi-stamping presses automatic production lines due to high costs and technical aspects of the problem in the country to promote the use of a very long time.
Therefore, we will use a relatively simple mechanical and aerodynamic bodies, the use of the automated gas source press (electronic signals sent by the press to control), and blanking parts scene and overturned, this device features: a simple structure, Reliable operation, the use of maintenance-friendly, and so on.
The whole design process, including the choice of programme, the principle of the matrix on the basis of the detailed design, analysis and calculations, that meet the requirements of the use of the device.


Key words: automatic processing lines, overturned the equipment, covering parts
