Method and system for combined shearing of steel plate
First Claim
1. A method for combined shearing of a steel plate, which adopts a combination of unrolling and pendulum shearing with laser cutting, wherein after a steel roll is cut by unrolling and pendulum shearing to obtain sheets having a specified length, a part or all of the sheets are directly conveyed to a stack as finished sheet materials and the other part or all of the sheets are transferred to a laser cutting line by means of lateral material discharge from a unrolling and pendulum cutting line, and are picked up by a loading robot and moved to a laser cutting position to subject to a secondary cutting, so as to finally obtain profiled sheet materials which are picked up by a discharged material handling and stacking robot for an operation of stacking the finished products.

Abstract
A method for combined shearing of a steel plate adopts a combination of unrolling and pendulum shearing with laser cutting, wherein after a steel roll is cut by unrolling and pendulum shearing to obtain sheets having a specified length, a part or all of the sheets are directly conveyed to a stack as finished sheet materials and the other part or all of the sheets are transferred to a laser cutting line by means of lateral material discharge from a unrolling and pendulum cutting line, and are picked up by a loading robot and moved to a laser cutting position to subject to a secondary cutting, so as to finally obtain profiled sheet materials which are picked up by a discharged material handling and stacking robot for an operation of stacking the finished products. By a method and system for combined shearing of a steel plate, the present invention achieves laser cutting of a profiled material by lateral material discharge from a blanking from a pendulum cutting line, and can share other functional segments of a production line; meanwhile, two blanking methods are combined to achieve cutting of a sheet of any shape, optimizing and improving the function of the production line and reducing the footprint and equipment investment costs.
