SUMMARY OF THE INVENTION An object of the present invention is to provide a hemming apparatus for a plate material and a hemming method using the same, which are relatively inexpensive in equipment investment for hemming work, easy replacement of a work tool for hemming work, .
As described above, according to the embodiment of the present invention, a hemming device for bending a part of a first panel and coupling the first panel to a second panel includes an EMF holder having an electromagnetic coil mounted on one surface thereof, a part of the first panel A power unit for applying an electromagnetic pulse to the electromagnetic coil to form an electromagnetic force on the first panel facing the electromagnetic coil, and a moving unit for moving the EMF holder.
The moving unit may include a robot that moves or rotates the EMF holder through a predetermined route.
The moving part including a cylinder arranged to push or pull the EMF holder; And the operation of the cylinder allows the EMF holder to be arranged to rotate about the hinge.
The second panel may be an outer panel disposed on an outer side of the vehicle body, and the first panel may be an inner panel disposed on the inner side of the vehicle body.
And a control unit for controlling the movement of the EMF holder through the moving unit and controlling a pulse applied to the electromagnetic coil through the power unit.
According to an embodiment of the present invention, there is provided a method of hemming a plate using a hemming device, the method comprising: contacting one surface of a first panel and a second panel; applying a pulse to the electromagnetic coil to apply an electromagnetic force to the first panel; And bending a portion of the first panel using the electromagnetic force and bringing the bent portion into close contact with the second panel so as to overlap the edge of the second panel.
And moving the EMF holder along a direction in which the first panel is bent, the EMF holder including the electromagnetic coil mounted on one surface thereof.
Bending a part of the first panel at a first predetermined angle in a first step of bending a part of the first panel and bending a part of the second panel secondarily at a second setting angle ≪ / RTI >
The first setting angle may be 90 degrees, and the second setting angle may be 45 degrees.
And a cylinder or a robot for moving the EMF holder, and the movement of the EMF holder can be controlled by controlling the cylinder or the robot to form a constant electromagnetic force between the electromagnetic coil and the first panel.
According to the present invention for achieving the above object, the flange portion of the outer panel is bent by using an electromagnetic repulsive force without directly contacting with the outer panel, so that the flange portion of the outer panel is fundamentally prevented from generating a scratch or crack can do.
In addition, by bending various types of outer panels using one EMF holder, the investment cost of the equipment for the hemming operation is reduced, the work tool for the hemming work is easily replaced, and various types of vehicles can be flexibly handled.
