Amada Press System’s line of world standard large-scale feeders are designed to support today’s high-tensile steel with stock widths up to 1,900 mm (74″) and stock thicknesses up to 6.0 mm (0.236″). The Large-Scale series of coil feeder includes hands free coil setting, shearing capabilities, and rewinding of unwound stock. In addition to blanking presses, this technology produces cut-to-length lines.
This product supports a wide range of high‐tensile steel plates, which are experiencing increasing demand. Straightening is performed automatically (by setting data), and a wide variety of motor capacities are available to accurately meet customer needs for coil flatness. An opening mechanism (up to 300 mm opening) is provided as a standard feature to improve productivity for maintenance.
For this product, we drew on our extensive track record and experience to provide optimal feed control. A measure roll (provided as a standard feature) also enables high feed accuracy. (PLC manufactured by Mitsubishi Electric; motor manufactured by Yaskawa Electric.)
An automatic coil threading function is included as a standard feature for the processes from loading to threading to meet customer needs for rationalization and reduction of preparation time.
A hydraulic crop shear is provided as a standard feature, and a double skid car enables incomplete coils to be unloaded, allowing preparation for the next coil to be rationalized. A movable end feeder is also provided as a standard feature to enable coils to be used right up to the ends.
