鋁箔后加工是一個企業(yè)至關(guān)重要的環(huán)節(jié)，關(guān)乎一個鋁企成品率與企業(yè)贏利點。成品率越高，企業(yè)贏利點相對就越大。當(dāng)然，成品率是每一個環(huán)節(jié)都要把控，規(guī)范化操作，還需要精良的設(shè)備與責(zé)任心強的、職工。    設(shè)備與操作規(guī)范我都不懂，不敢指手畫腳，我只能在分切用刀上依據(jù)實踐剖析一下。下面我講講分切為什么會發(fā)生翹邊、多邊、掉粉。翹邊、多邊、掉粉問題除去資料本身與設(shè)備問題，大部分都與刀片相關(guān)。
Aluminum foil post-processing is an important part of an enterprise, which is related to the yield and profit point of an aluminum enterprise. The higher the yield is, the greater the profit point is. Of course, the finished product rate should be controlled in every link, standardized operation, and also requires sophisticated equipment and responsible leadership and staff. I don't know the equipment and operation specifications. I dare not point my finger at them. I can only analyze them on the cutting knife according to practice. Next, I'll talk about why slicing happens, such as edge warping, multilateral and powder dropping. The problems of edge warping, multilateral and powder dropping are mostly related to blades, except for the data itself and equipment problems.
通常鋁箔分切主要有兩種刀片。一種是圓刀片，一種是片式劃刀片也稱剃刀。剃刀片是固定一個點位，以資料收卷被迫切開、劃開。鋁箔為自動分切，速度越快，刀片的阻力相對越小。越慢與之相反。刀片的厚薄與阻力相對應(yīng)的。刀片越厚，阻力越大。越薄與之相反。由于剃刀片是劃切固定不動的，刀口與箔、薄資料觸摸時，切點簡單呈現(xiàn)疲勞發(fā)熱，所以過一段時間后就會刀口不尖利，刀鈍就會呈現(xiàn)撕裂現(xiàn)象，呈現(xiàn)掉粉毛邊在所難免。當(dāng)然，這些與分切視點也有關(guān)系。選用好的剃刀片是處理這些問題的，陶瓷刀片應(yīng)該是。
Usually there are two kinds of blades for cutting aluminium foil. One is round blade, the other is blade blade, also known as razor. The razor blade is fixed at a point, and is forced to cut and cut with data winding. Aluminum foil is cut automatically. The faster the speed, the smaller the resistance of the blade. The slower it is, the opposite is true. The thickness of the blade corresponds to the resistance. The thicker the blade, the greater the resistance. Thinner is the opposite. Because the razor blade is cut and fixed, when the blade touches foil and thin data, the cutting point simply presents fatigue and fever, so after a period of time, the blade will not be sharp, the knife will be blunt, showing tearing phenomenon, showing that the powdered edge is unavoidable. Of course, these are also related to the sharding perspective. Choosing a good razor blade is the first choice to deal with these problems. Ceramic blade should be the first choice.
現(xiàn)在一切鋁箔企業(yè)都想加工高附加值的電池箔，但電池箔驗收規(guī)范堪稱嚴(yán)苛。代表性鋰電池企業(yè)中像：比亞迪、ATL、A123電芯企業(yè)，對鋁箔的驗收規(guī)范堪稱嚴(yán)苛。對箔要求極高，并且對寬幅、粉塵、翹邊也算是嚴(yán)苛中的嚴(yán)苛。所以關(guān)于產(chǎn)值并不高的電池箔企業(yè)，后加工分
Now all aluminium foil enterprises want to process high value-added battery foil, but the acceptance criteria for battery foil can be rigorous. Among the representative lithium battery enterprises, such as BYD, ATL and A123, the acceptance criteria for aluminium foil are rigorous. The requirement for foil is very high, and the width, dust and edge warping are also rigorous. So for battery foil enterprises with low output value, post-processing points
［陶瓷與鋼刀片的區(qū)分］在高速分切中，鋼刀片散熱系數(shù)差，分切速度越高，摩擦系數(shù)就越大，發(fā)生熱量就會越多，截留在鋼刀片的熱量就越多。分切過程中箔與刀片磨擦?xí)l(fā)生熱量，一部分熱量跟著收卷已在常溫下散去，而另一部分熱量就留在了鋼刀片上，并且是累計熱量，分切時間越長、速度越高，留在刀片上的熱量就會越多。這樣刀片又把熱量傳導(dǎo)到箔上，就形成了對箔傳熱，由于這時候刀片已呈現(xiàn)高溫再與箔觸摸就會發(fā)生粉塵黏刀，使刀片使去尖利度，形成掉粉、翹邊狀況。同時刀片過熱又會使刀片失掉了原有的硬度，而失掉耐用性與尖利度，從而發(fā)生掉粉、荷葉邊等。切成品率，至關(guān)重要。

[Differentiation between ceramic and steel blade] In high-speed cutting, the heat dissipation coefficient of steel blade is poor. The higher the cutting speed, the greater the friction coefficient, the more heat generated, and the more heat retained in the steel blade. During the cutting process, the friction between foil and blade will generate heat. Some of the heat dissipates with the winding at room temperature, while the other part of the heat remains on the steel blade and is the accumulated heat. The longer the cutting time and the higher the speed, the more heat left on the blade. In this way, the blade transfers heat to the foil, which forms heat transfer to the foil. Because the blade has high temperature and then touches the foil, dust sticks to the blade, which makes the blade sharpen and form the condition of powder dropping and edge warping. At the same time, the blade will lose its original hardness, durability and sharpness, resulting in powder loss, lotus edge and so on. Cutting rate is very important.
［鋁箔圓刀片的兩種分切方法］  圓刀片分切有一部分是鋁箔自動分切，也就是圓刀片被箔資料收卷帶動旋轉(zhuǎn)，與剃刀片是同樣的方法，僅僅有更多刃口的與資料觸摸。這種方法由于刀片本身是被迫的，受資料的速度影響，觸摸點、刀口是下壓方法。資料收卷是有跳動的，由于刀片本身沒有動力，收卷的動搖易出翹邊。
[Two kinds of cutting methods of aluminium foil round blade] Round blade cutting is part of automatic cutting of aluminium foil, that is, round blade is rotated by foil data winding, the same method as razor blade, only more edges and data touch. This method is forced by the blade itself and affected by the speed of data. Touch points and knife edges are downward pressing methods. Data winding is jumpy, because the blade itself has no power, the winding shake easily out of the warp edge.
圓刀自動分切，這是現(xiàn)在較通用的方法。圓刀自動分切有兩種，一種是同軸滾動，一種是獨臂式電機驅(qū)動。個人更看好獨臂式驅(qū)動，這種可以依據(jù)資料厚度不同，調(diào)節(jié)刀片轉(zhuǎn)速。  圓刀常規(guī)狀況以上下刀合作分切，而咱們通常看到的是蝶形上刀，為什么咱們要用蝶形上刀呢？這是從日韓傳過來的，由于平行度不行，用蝶形刀片可以補償這方面的缺乏，咱們通常都要把蝶形上刀給壓貼合在下刀上，就是怕平行度不行，切不出好的產(chǎn)品。這點請大家注意：德國人，不必蝶形碗狀刀片。他們的刀片，都是一個平面，由于他們的刀片平行度誤差不超過0.5um。但通常德國分切刀片厚度都會挑選在2mm以上。由于刀片越薄，平行度公差越難控制。但厚度越厚，阻力越大，越簡單呈現(xiàn)翹邊、壓痕、掉粉狀況。個人，更傾向于薄刀片，以為刀片越薄，切出的
Round knife automatic cutting, this is the most common method now. There are two kinds of automatic cutter slitting, one is coaxial rolling, the other is driven by one-arm motor. Individuals prefer one-arm drive, which can adjust blade speed according to different data thickness. Round knife is usually cut with top and bottom knives, but what we usually see is Butterfly Top knife. Why should we use Butterfly Top knife? This is from Japan and Korea, because parallelism is not good, butterfly blade can compensate for this lack, we usually have to press the butterfly top knife on the lower knife, is afraid that parallelism is not good, can not cut good products. This point, please note: Germans do not need butterfly bowl blades. Their blades are all flat, because their parallelism error is less than 0.5 um. But usually the thickness of the cutting blade in Germany is more than 2 mm. The thinner the blade, the more difficult it is to control the parallelism tolerance. However, the thicker the thickness is, the greater the resistance is, and the simpler the situation of warping, indentation and powder dropping is. Individuals prefer thin blades, thinking that the thinner the blade, the more cut out.
