Abstract
A metal plate shearing apparatus, a control method thereof, and a metal plate shearing method are disclosed. The metal plate shearing apparatus includes a lower pad, an upper pad installed on the lower pad to ascend and descend and configured to press and fix an upper surface of a metal plate of a cut target placed on the lower pad, a shear blade installed adjacent to one side surface of the upper pad to ascend and descend and configured to shear a cutting line of the metal plate by descending, and a heating device configured to locally heat the cutting line of the metal plate.
Claims8
A metal plate shearing apparatus comprising:
- a lower pad;
- an upper pad installed on the lower pad to ascend and descend and configured to press and fix an upper surface of a metal plate placed on the lower pad;
- a blade installed adjacent to one side surface of the upper pad to ascend and descend and configured to shear the metal plate at a cutting line by descending;
- and
- a heater device configured to locally heat the cutting line of the metal plate, and
- wherein the heater device is installed to ascend and descend in a state adjacent to one side surface of the lower pad below the blade, and
- wherein the heater device includes;
- a support block disposed adjacent the one side surface of the lower pad to ascend and descend;
- an induction heating heater installed on an upper portion of the support block to heat the cutting line of the metal plate;
- and
- a heater accommodating portion provided in a groove shape on the upper portion of the support block to accommodate the induction heating heater and having an upper surface of the groove open.
The metal plate shearing apparatus according to claim wherein the heater device further includes an induction heating shield provided on the inner surface of the heater accommodating portion to block heating of the support block by the induction heating heater.
The metal plate shearing apparatus according to claim further comprising a cooling device configured to cool an upper edge portion of the lower pad, a lower edge portion of the upper pad, and a lower portion of the blade, which are adjacent to the cutting line of the metal plate.
