Hydraulic cylinder 76 drives c-type knife rest 71 that workpiece is carried out bending;
7), after c-type knife rest 71 carries out bending to workpiece, upper mold hydraulic cylinder 13 drives frame 1 to stop after returning to initial position
Only, the most just completing a flexing movement, the rotation controlling electric magnet 931 can be processed many Edge Bends of part, bending
System constantly carries out above-mentioned action according to computer electronic drawing processing request can complete polygon forward and reverse bending of workpiece.
After work pieces process completes, electric magnet 931 dead electricity departs from workpiece, starts blanking servomotor 33 and drives lower trolley 32 to push workpiece
Leave workbench 5.After workpiece leaves workbench 5, start blanking servomotor 33, feeding X-axis servomotor 913, feeding Z axis
Servomotor 921, electric magnet servomotor 933 (reversion) make it drive lower trolley 32 and electric magnet 931 to return to initial position
(returning to initial position rear motor out of service), the most whole workpiece is processed complete.
Schematically being described the present invention and embodiment thereof above, this description does not has restricted, institute in accompanying drawing
Show is also one of embodiments of the present invention, and actual structure is not limited thereto.So, if the common skill of this area
Art personnel enlightened by it, in the case of without departing from the invention objective, designs and this technical scheme without creative
Similar frame mode and embodiment, all should belong to protection scope of the present invention.
