4.1 Main component structure
4.1.1 Whole machine
The frame adopts box shaped structural components welded with steel plates. The welding process is mature, and the groove form and weld selection meet the standards. Using CO2 Gas shielded welding, special inspections such as non-destructive testing of important welds (points). The structural components of the rack box must be welded and formed before proceeding . The treatment of eliminating internal stress. Eliminate the deformation of the components and the overall structure of the press body caused by its stress after long-term operation Stability of structural geometric accuracy.
The press machine has four operation actions including cutting (OFF), single operation, continuous operation, and inch movement (forward and reverse), as well as emergency stop function.
