|1. (WO2017036127) METHOD AND SYSTEM FOR DYNAMICALLY FOLLOWING LASER CUTTING WITH SYNCHRONOUS SHEET TRANSFERRING|
|Applicants:||BAOSHAN IRON & STEEL CO., LTD.
|Title:||METHOD AND SYSTEM FOR DYNAMICALLY FOLLOWING LASER CUTTING WITH SYNCHRONOUS SHEET TRANSFERRING|
A system for dynamically following laser cutting with synchronous sheet transferring comprises: at least one machining location (1); synchronous sheet transferring units (2, 2') employing magnetic belt groups and respectively disposed at a load incoming side and a load exit side of the machining location, wherein each magnetic belt (C11, C12, C13, C14, C21, C22, C23, C24, C25) in the magnetic belt groups can be extended or retracted, and a gap therebetween is adjustable; a laser cutting unit (3) disposed at the machining location and comprising at least one laser cutting machine (31) and a laser cutter head (32) thereon; a material handling and stacking unit (4) comprising a stacking platform (41) and a stacking robot (42), wherein the stacking platform is disposed at an outer side of the magnetic belt group of the synchronous sheet transferring unit at the load exit side of the machining location; a waste conveyor belt device (5) disposed at a side of the machining location in a direction perpendicular to a load incoming direction; a smoke and dust processing device (6) and a real-time measurement device (7) for cutting strip steel that are disposed at each machining location; a sheet position detection device (8) in front of a sheet stack and disposed at a material handling location of the magnetic belt group at an outer side of the load exit side of the machining location; a cutting control system controlling the above-mentioned units, and extension or retraction of the magnetic belts following the laser cutter head. Also disclosed is a laser cutting method applied to the system for dynamically following laser cutting with synchronous sheet transferring. The system and method can realize dynamic following of a cutting process with the magnetic belt groups to accelerate machining, thereby further increasing the throughput.
