GENERAL
Type Cut-to-length line for transformer lamination is the special equipment for transformer lamination manufacturing. This is our new generation of cut-to-length line. The line is used to punch and shear sheets of small-medium all oblique joint core, including side leg sheets, the yoke and central leg sheets. The silicon steel coil is punched and sheared to be certain shape and size of laminations, then be diverted and tidied in order to use in stacking. The main sheet shapes could refer to the following lamination drawing (see Appendix1).
The advanced control system is adopted to make sure accurate and stable operation. Embedded operating terminal is easy to complete parameter input.
