Process flow and parameters for cross cutting production line

铝带横剪机组是用于对厚为2～12mm铝及铝合金卷材进行横向精确裁剪，并按产品要求整齐垛板的设备。剪切最大长度可达到11m。拉矫生产线铝卷在张力辊组施加的2.0～20 kN的张力作用下，连续通过上下交替布置的多组小直径弯曲辊，在拉伸和弯曲的联合作用下，沿长度方向产生了塑性延伸，使带材各条纵向纤维的长度趋于一致，改善带材平直度。机组运行速度可达到200m/min。厚板矫直生产线辊子的位置与被矫直制品运动方向成某种角度，两个或三个大的是主动压力辊，由电动机带动作同方向旋转，另一边的若干个小辊是从动的压力辊，它们是靠着旋转着的圆棒或管材摩擦力使之旋转的。为了达到辊子对制品所要求的压缩，这些小辊可以同时或分别向前或向后调整位置。制品被辊子咬入之后，不断地作直线或旋转运动，因而使制品承受各方面的压缩、弯曲、压扁等变形，最后达到矫直的目的。该生产线矫直力30MN。

The aluminum strip cross cutting unit is a device used for accurately cutting aluminum and aluminum alloy coils with a thickness of 2-12mm horizontally, and stacking them neatly according to product requirements. The maximum cutting length can reach 11m. Under the tension of 2.0-20 kN applied by the tension roller group, the aluminum coil in the straightening production line continuously passes through multiple sets of small diameter bending rollers arranged alternately up and down. Under the combined action of stretching and bending, plastic extension occurs along the length direction, making the length of each longitudinal fiber of the strip tend to be consistent and improving the flatness of the strip. The operating speed of the unit can reach 200m/min. The position of the rollers in the thick plate straightening production line is at a certain angle to the direction of movement of the straightened product. Two or three of the larger rollers are the active pressure rollers, which are driven by an electric motor to rotate in the same direction, while several small rollers on the other side are the passive pressure rollers, which are rotated by the frictional force of the rotating round rod or pipe material. In order to achieve the compression required by the rollers for the products, these small rollers can be adjusted forward or backward at the same time or respectively. After being bitten by the roller, the product continuously undergoes linear or rotational motion, thus subjecting the product to various forms of compression, bending, flattening, and other deformations, ultimately achieving the purpose of straightening. The straightening force of this production line is 30MN.

四、深加工工艺1、拉丝处理工艺工艺主要流程分为脱酯、沙磨机、水洗3个部分。在铝板拉丝制程中，阳极处理之后的特殊的皮膜技术，一般用直径0.1毫米的不锈钢丝刷或百洁布带刷，也可用尼龙砂带加工，可以使铝板表面生成一种含有该金属成分的皮膜层，清晰显现每一根细微丝痕，从而使金属哑光中泛出细密的发丝光泽。近年来，越来越多的铝板产品的金属外壳都使用了金属拉丝工艺 ，以起到美观，抗侵蚀的作用。2、蚀刻处理工艺先用用枣木碳研磨，去掉油腻、划痕，磨出哑光表面。然后用丝网版印上纹样，油墨型号为80-39、80-59、80-49等。印完纹样后放进电炉内烘干，然后用即时贴封住后面，用胶带封边，进入腐蚀工艺。

4、 Deep processing technology 1. The main process of wire drawing treatment technology is divided into three parts: de esterification, sand mill, and water washing. In the aluminum plate drawing process, the special coating technology after anodizing is generally achieved by using a stainless steel wire brush or scouring pad brush with a diameter of 0.1 millimeters, or by processing with a nylon sand belt. This can create a coating layer containing the metal component on the surface of the aluminum plate, clearly showing every fine wire trace, thus giving the metal matte a fine hair like luster. In recent years, an increasing number of aluminum plate products have adopted metal wire drawing technology for their metal shells, in order to achieve aesthetic and corrosion-resistant effects. 2. The etching process first uses jujube wood carbon to grind, remove grease and scratches, and grind a matte surface. Then use screen printing to print the pattern, with ink models such as 80-39, 80-59, 80-49, etc. After printing the pattern, put it in an electric furnace for drying, then seal the back with instant tape, seal the edges with adhesive tape, and enter the corrosion process.

铝板的腐蚀液配方如下：三氯化铁50% ：硫酸铜50%，适量的水，温度在15～20°之间。铝板腐蚀时应平放，在腐蚀的过程中纹样上溢出赭红色的滓渣，应随时用毛刷去掉，铝面上冒出大量泡泡，滓渣随泡泡浮起。铝板的腐蚀时间大约在15～20min左右就可完成。3、电泳涂装工艺工艺流程：脱脂→热水洗→水洗→中和→水洗→阳极氧化→水洗→电解着色→热水洗→水洗→电泳→水洗→干燥。

The formula for the corrosion solution of aluminum plate is as follows: 50% ferric chloride, 50% copper sulfate, an appropriate amount of water, and a temperature between 15-20 ° C. When the aluminum plate is corroded, it should be placed flat. During the corrosion process, reddish brown slag overflows from the pattern and should be removed with a brush at any time. A large number of bubbles will appear on the aluminum surface, and the slag will float up with the bubbles. The corrosion time of aluminum plate can be completed in about 15-20 minutes. 3. Electrophoretic coating process flow: degreasing → hot water washing → water washing → neutralization → water washing → anodizing → water washing → electrolytic coloring → hot water washing → water washing → electrophoresis → water washing → drying.

在阳极氧化的基础上，通过电泳的作用，在氧化膜上均匀覆盖上一层水溶性丙烯酸漆膜，使型材表面形成阳极氧化膜和丙烯酸漆膜复合膜。铝板带进入固体份7%～9%、温度20～25℃、pH8.0～8.8、电阻率(20℃)1500～2500Ωcm、电压(DC)80～25OV、电流密度15～50 A/m2的电泳池经过1～3 min的时间电泳可涂膜7～12μm厚度。

On the basis of anodic oxidation, a water-soluble acrylic paint film is uniformly covered on the oxide film through electrophoresis, forming a composite film of anodic oxide film and acrylic paint film on the surface of the profile. Aluminum strip can be coated with a film thickness of 7-12 μ m after 1-3 minutes of electrophoresis in an electrophoresis cell with a solid content of 7% -9%, temperature of 20-25 ℃, pH of 8.0-8.8, resistivity of 1500-2500 Ω cm (20 ℃), voltage of 80-25OV (DC), and current density of 15-50 A/m2.
