摘 要
目前很多沖壓生產(chǎn)線的模下廢料均由人工清掃,機(jī)箱裝載。手工生產(chǎn)線需停機(jī)清掃。自動生產(chǎn)線雖不停機(jī),但清掃時極不安全。同時手工清掃廢料及目前廢料收集方式使整個生產(chǎn)現(xiàn)場顯得零亂。廢料滿地散落,場地不清潔,人工清除廢料勢必停機(jī)作業(yè),影響生產(chǎn)效率。
隨著產(chǎn)品更新替換速度的加快,產(chǎn)品的規(guī)格變化多端,多種少量之生產(chǎn)方式已非常之普遍。各種模具墊腳,墊腳間距幾何位置不一,并隨快速換模的導(dǎo)入,夾模器的干涉,規(guī)格品的輸送裝置已無法適應(yīng)。如何從模下自動清除廢料,并適應(yīng)其種種之變化,成為同行業(yè)界的一個難點。為滿足生產(chǎn)的需求,提高工作效率,一種獨特的輸送裝置可自行清除模下廢料。該裝置由安裝架、工織皮帶輸送帶、廢料輸送機(jī)等部件組成。該輸送裝置設(shè)計的獨特之處在于:使用一臺馬達(dá)同時驅(qū)動多條輸送帶,解決了一臺馬達(dá)驅(qū)動一條輸送帶所帶來的橫向空間不夠的問題;輸送帶橫向位置可任意調(diào)整,已適應(yīng)不同的墊腳位置;一種輸送帶寬度可適應(yīng)一定范圍的墊腳間距,輸送帶可任意組合,已適應(yīng)不同寬度;換模時可方便地移動輸送帶,且各皮帶整體及單個皮帶伸入模具下的深度可調(diào),適應(yīng)不同的模具尺寸;換線時,可方便地更換輸送帶;超薄皮帶可越過夾模器或壓板的阻擋,更好地利用空間。
沖壓廢料自動輸送裝置是一種適應(yīng)性強(qiáng),效率高,安全可靠,靈活多變的組合式廢料輸送設(shè)備,配以鏈板式輸送機(jī),對每一條生產(chǎn)線的廢料進(jìn)行集中收集,或配以電磁送料機(jī),廢料箱進(jìn)行單臺沖床廢料收集,從而可進(jìn)一步提高沖壓生產(chǎn)的自動化程度,實現(xiàn)沖壓作業(yè)區(qū)的無人化,極大地提高生產(chǎn)效率。

ABSTRACT
At present under very many ramming production line mold waste material by hand sweeping, case loading. The manual production line needs the engine off to sweep clear. Automated production line although not engine off, when sweeps clear is not extremely secure Simultaneously manually sweeps clear the waste material and the present waste material collection mode causes the entire production scene to appear in disorder. The waste material everywhere scatters, the location is not clean, the man-power will clear away rubbish inevitably the engine off job, will affect the production efficiency.
Along with product update replace speed speeding up, the product specification , the many kinds of few production method has been extremely common. Each kind of mold pad foot, fronts the foot spacing several positions not one, and along with fast trades the mold inducting, clamps the mold interference, the specification feed way has-been unable to adapt. How automated clears away rubbish from the mold, and adapts its all sorts of changes, becomes the colleague field difficulty. In order to satisfy the production the demand, enhances the working efficiency, one kind of unique feed way may voluntarily clear under the mold the waste material. This equipment by is peaceful, the labor weaves part and so on leather belt conveyor belt, waste material conveyer is composed. This feed way design unique occupying to: Uses a motor simultaneously to actuate the multi- strip conveyor belt, solved a motor to actuate the crosswise spatial insufficient question which a conveyor belt brought; The conveyor belt lateral attitude may willfully adjust, adapted the different pad foot position; One kind of conveyor belt width may adapt the certain scope pad foot spacing, the conveyor belt may willfully combine, adapted the different width; Trades when the mold may conveniently move the conveyor belt, also various leather belts overall and the single leather belt enters under the mold the depth to be possible to move, adapts the different mold size; When trades the line, but conveniently replaces the conveyor belt; The ultra thin leather belt may leapfrog clamps the mold or clamp preventing, uses the space well.
The ramming waste material automated feed way is one compatibility strong, the efficiency high, secure is reliable, the flexible combined type waste material conveyor, matches by the chain beat conveyer, carries on the centralism collection to each production line waste material, or matches by the electromagnetism feeding computer, the waste box carries on the single punch press waste material collection, thus may further enhance the ramming production the automatist, implements ramming operation area nobody to melt, enormously enhances the production efficiency.
Key words: waste material; automate; feed;
matches by the electromagnetism feeding computer
