In some cases, in order to meet the process requirements, reduce the weight, dissipate heat and ventilation, and achieve attractive appearance and design effects, a hole is punched in the square sheet metal piece, so the embodiment is used for punching holes with different diameters in the centers of square sheet metal pieces with different sizes.
Firstly, according to the size of square metal plates to be punched and the size of holes to be punched, a lower die 8 and a punching head 23 with different specifications are respectively arranged at the upper end of a workbench 1 and the lower end of a mounting plate 6, then according to the size of the metal plates to be punched, a hydraulic cylinder II 5 is started to drive a hinging block 24 to lift, when the hinging block 24 lifts, a plurality of connecting rods I25 are simultaneously rotated, the connecting rods I25 drive a plurality of limiting plates 27 to simultaneously slide on a limiting frame 26, squares with different area sizes are formed among the limiting plates 27, so that a placing space for forming the metal plates is provided, then the metal plates to be punched are arranged in a die cavity of the lower die 8, and then a hydraulic cylinder I3 is started to drive the mounting plate 6 to descend, so that the punching head 23 descends to punch the metal plates.
After the sheet metal piece is stamped and formed, the mounting plate 6 is driven to ascend, the stamping head 23 is far away from the sheet metal piece, a sufficient distance is reserved between the stamping head 23 and the sheet metal piece, then the first electric push rod 10 is started to drive the frame 12 to move leftwards, the first electromagnet 17 is located above the sheet metal piece, then the third electric push rod 15 is started to drive the first electromagnet 17 to descend, the first electromagnet 17 is contacted with the sheet metal piece, then the first electromagnet 17 is electrified, so that magnetic force is generated, the first electromagnet 17 can absorb the sheet metal piece, then the first electromagnet 17 is driven to ascend again, and the sheet metal piece can be taken out upwards by the first electromagnet 17, so that the sheet metal piece is separated from the die cavity.
