目前分离铝板比较常用的方法是用气刀。高压压缩空气通过空气刀,吹到纸页边缘,强劲的气流在纸页顶部吹散1-2页。压缩空气压力越高,流量越大,对板材的吹制力就越大。因此,一般使用8-10bar的压缩空气:由于压线一般使用6ba以下的压缩空气,所以需要单独配置空气刀的空压机。铝板生产厂家为了保证高压气流j-lu压缩空气稳定供给气割机,在气割机附近设置蓄能器,以满足气割机瞬时大流量的要求。当蓄能器到达气刀气管时,必须考虑气刀全部打开时的极限流量要求。否则,当气刀使用过多时,压降会过大,导致气刀的吹风力下降,影响劈裂效果。为了节约能源,1气刀采用独立的电磁阀控制。这样,在堆垛过程中,每一把气刀是否使用,何时开启,何时关闭,都可以通过参数来控制。
At present, the commonly used method to separate aluminum plate is to use air knife. High pressure compressed air through the air knife, blowing to the edge of the paper, strong air flow in the top of the paper spread 1-2 pages. The higher the pressure of compressed air, the greater the flow rate, the greater the blowing force on the plate. Therefore, 8-10bar compressed air is generally used: since the compressed air below 6BA is generally used for pressing line, the air compressor with air knife shall be configured separately. In order to ensure the stable supply of high pressure air j-lu compressed air to the gas cutting machine, aluminum plate manufacturers set accumulator near the gas cutting machine to meet the requirements of instantaneous large flow of the gas cutting machine. When the accumulator reaches the air knife gas pipe, the limit flow requirements when the air knife is fully opened must be considered. Otherwise, when the air knife is used too much, the pressure drop will be too large, which will lead to the decrease of blowing force of the air knife and affect the splitting effect. In order to save energy, 1 air knife is controlled by an independent solenoid valve. In this way, in the stacking process, whether, when to open and when to close each air knife can be controlled by parameters.
还有各种气刀设计,常见的有长刀和圆刀。矩形工作范围面积大,但是能源消耗的增加,压降很大,适合应用程序可以准确找到上面的一块金属板,如传统的方式公开支持使用液压起重车,每10 mm在车顶,寻找一片的更高位置,由于开放支撑汽车不能精确控制顶部位置的表,必须工作范围非常宽带钢空气刀。圆形气刀作用面积小,气流集中,压降小,能耗低。但是,由于作用面积小,要求空气喷嘴精确到更大_1,使板材表面有一层材料,所以铝板堆垛小车采用电机准确控制小车升降。近年来,一模两件的铝板越来越多。同时,两块板的厚度不一样,所以需要分别控制升降小车的两边,这样才能精确的控制两块板的位置。
There are also a variety of air knife design, common long knife and round knife. Rectangular work area is large, but the increase of energy consumption, pressure drop is very large, suitable for applications can accurately find a piece of metal plate above, such as the traditional way to open support the use of hydraulic crane car, every 10 mm in the roof, looking for a piece of the highest position, because the open support car can not accurately control the top position of the table, it must work in a very wide range of steel air knife. The utility model has the advantages of small acting area, concentrated air flow, small pressure drop and low energy consumption. However, due to the small action area, the air nozzle is required to be accurate to the maximum ﹤ 1, so that there is a layer of material on the surface of the plate, so the aluminum plate stacking trolley adopts the motor to accurately control the lifting of the trolley. In recent years, the first mock exam has two aluminum plates. At the same time, the thickness of the two plates is different, so it is necessary to control the two sides of the lifting car respectively, so as to accurately control the position of the two plates.
为了提高设备的利用率,通用铝板冲床生产线同时具有钢板生产功能。因此,气刀需要集成到原磁分压器中。气刀可以集成到除法器或磁除法器的侧面。考虑到磁分配器集成的方案易于精确控制空气喷嘴与板之间的距离,更有利于分配器的工作,建议采用该方案。
In order to improve the utilization rate of the equipment, the production line of general aluminum plate punch has the function of steel plate production. Therefore, the air knife needs to be integrated into the original magnetic divider. The air knife can be integrated into the side of the divider or magnetic divider. Considering that the integrated scheme of the magnetic distributor is easy to control the distance between the air nozzle and the plate accurately, which is more conducive to the work of the distributor, the scheme is recommended.
