Abstract
An uncoiling and blanking method includes uncoiling a coiled strip, straightening, cutting off the leading end, moving into a looper, moving out of the looper, then cleaning the surface of the coiled strip, and flattening; conveying the coiled strip on a pinch roller to perform laser cutting and blanking, wherein dual static laser cutting heads are used for cutting the coiled strip during the laser cutting, and the cut-away waste materials fall down from the cutting region and are conveyed to the outside; and after the completion of cutting, finally cutting off the obtained sheets from each other, receiving them by a receiving device and conveying same on a conveying belt to a picking up and stacking region to stack the sheets. An uncoiling and blanking method of the present invention adopts laser static cutting, can effectively improve the operation speed and yield by means of cooperative operation of two laser cutting heads, replaces the die blanking method, and has no die or maintenance cost associated therewith, requires no die stacking space, has a more flexible operation mode, simplifies the layout of the production line, and is easy to handle.
