Description

Technical Field

[0002] The application number CN202010142053.2 discloses a sheet bending device and a sheet bending method, and the invention method is as follows: 1. Place the metal plate on the upper side of the flat plate, and place the fold position to be bent above the rectangular long hole, and two pressure strips are pressed on the metal plate to fix the metal plate; 2. When the output shaft of the motor II rotates, it drives the disc to rotate. When the disc rotates, the gear ring on the rotating disc will roll left and right on the rack, thereby driving the hollow seat to slide on the trapezoidal slide rail I, so that the grinding disc will move left and right while reciprocating and lifting, and intermittently grind a plurality of transverse grooves on the metal plate along the fold; 3. After intermittently grinding a plurality of transverse grooves on the metal plate, the two electric push rods are extended at the same time to raise the horizontal beam and the two vertical beams, and the bending rod is inserted between the upper parts of the two vertical beams.
