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.

Uncoiling and blanking method

A metal plate loading/unloading and cutting method and system comprises: a block cart and a sheet cart both of which are arranged on a guide rail; a cutting operation unit arranged at one side of the guide rail; a carrying and stacking robot arranged between the cutting operation unit and the guide rail of the block cart and the sheet cart, a robot external shaft being parallel to the cart guide rail and extending over two fast moving table waiting stations of the cutting operation unit; and a waste material conveying device arranged below the two cutting stations of the cutting operation unit. The present invention can effectively increase material utilization efficiency and further enlarge the range in production and machining, and is especially suitable for providing production of small-batch vehicle models and trial production of new vehicle models.

Metal plate loading/unloading and cutting method and system

A longitudinal metal plate loading/unloading and cutting method and a system thereof involve two longitudinally moving loading/unloading and cutting operation lines arranged in parallel, each of the operation lines comprising a block loading station, a cutting station, a sheet unloading station, and a carrying and stacking robot arranged between the two operation lines, which are arranged in succession, wherein the two operation lines have block loading directions opposite to each other. The present invention can effectively increase the cutting production rate and yield, and also provide a more reasonable layout of the system.

Longitudinal metal plate loading/unloading and cutting method and system thereof

The present invention discloses a method of motor vehicle sheet blanking and a system of the same, wherein the blanking method comprises: firstly, nesting for motor vehicle sheet material, and cutting it into group sheets with a shape and size confirmed by the multi length of the sheet; next, designing a backing die depending on scraps to be cut from the group sheet, and hollowing in areas corresponding to blanking openings in the backing die, in which the dimensions of the blanking openings are greater than that of the actual scraps to be cut; then, placing a group sheet onto the backing die; laser cutting the group sheet based on the shape of motor vehicle sheet, the cut scraps dropping through the blanking openings in the backing die onto a scrap conveyor belt underneath; stacking the cut sheets. The present invention can effectively process scraps cut from sheets and improve the blanking efficiency.
