Sheet metal processing bending equipment applicationSheet metal processing has become an important processing technology, the processing process must be applied to a variety of equipment, according to this equipment can be detailed processing, but also because of the processing of the necessary equipment, so manufacturers also need to do a good job in the selection of equipment, so to ensure the final processing of the actual effect.First, according to the real requirements of processing to carry out the selectionIn order to choose the equipment for processing, it is important to first understand what your specific needs are. Some manufacturers must process some unique workpieces, and some manufacturers are to process customized workpieces, so the demand for processing is not the same, there is no doubt that there is a difference in the selection of sheet metal processing equipment, for example, it must be applied to CNC bending machines.Second, according to the processing of the workpiece to carry out selectionIn addition to the actual processing requirements of the manufacturer, the performance of the processed workpiece is to be understood. Nowadays, sheet metal processing is still to process different workpieces, so different workpieces, or there will be different characteristics, including thin and thick and other levels, all are different, so this point is to pay special attention to, according to the processing of the workpiece to choose, in the processing process will be easier.Third, sheet metal bending parametersIn the process of sheet metal processing, bending processing is one of the processing processes, and the bending and forming of metal is achieved by applying force to the bending lever on the bending machine. In order to ensure that the processed workpiece meets our requirements, we need to select the accurate bending coefficient when performing sheet metal bending processing.Bending factor:The bending factor belongs to the category of sheet metal processing. For example, if you fold a part with an angle iron pattern, the dimensions on both sides are A and B, then the actual processing is to be unfolded by punching machine processing first, and its unfolded size is A + B - corresponding bending coefficient = unfolded size. The bending expansion coefficient is an experienced sheet metal bending master, based on years of design experience repeated verification and summed up the data-based things, later sheet metal bending master can directly set into the calculation formula can get the bending structure unfolded plate size.Method for determining bending coefficient in sheet metal processing:A very simple bending factor calculation method belongs to the empirical formula of 90 degree bending coefficient: 1.7 times the material thickness calculation method.During 90° sheet metal bending, subtract 1.7 times the material thickness from the right angle bending. If the material is a 1mm iron plate, the bending angle is 90 degrees, and the bending size is 100 and 50, the calculation method is: 100+50-1.7=148.3mm. The calculation is the unfolded length. This 1.7 is said to be 1.6 or 1.65 times. Yes, it can be adjusted a little. Since the bending dies used by each gold factory are not exactly the same, the error is very small, and it cannot be adjusted, and the requirements can also be slightly adjusted.Here we talk about a special angle, which can be calculated in a simple way. When the bending angle of sheet metal processing is 135°, the bending coefficient can reduce the thickness of the material by 0.5 times. If the material is a 1mm iron plate, the bending angle is 135 degrees, and the bending size is 100 and 50, the calculation and unfolding method is: 100+500.5=149.5mm. Other sheet metal thicknesses can also be calculated in this way. Only suitable for 135 degrees, other angles are not available.There is also a special angle in the bending of sheet metal processing, that is, sheet metal frills (also known as dead edges) can be calculated in a simple way. The bending coefficient is equal to 0.4 times the thickness of the metal plate. For example, if the material is a 1mm iron plate, the bending is a crushed dead side, and the bending dimensions are 100 and 10, respectively, the calculation and expansion method is 10010-0.4=109.6 mm. This calculation is an empirical formula and is very accurate.In summary, it is the method of determining the bending coefficient in sheet metal processing. However, due to the use of different equipment, some sheet metal processing manufacturers, in the determination of sheet metal bending coefficient, there may be certain differences, therefore, we should analyze the actual situation to determine the bending coefficient of suitable sheet metal processing.
