Abstract: The present invention relates to a mutually-pulling type sheet forming apparatus and, more specifically, a mutually-pulling type sheet forming apparatus which comprises a die; a punch facing the die across a sheet; a first magnetic unit which is fixed between the die and the punch and which has first magnetic flux in a first direction; and a second magnetic unit which has second magnetic flux in the first direction and which changes the direction of the second magnetic flux to a second direction opposite to the first direction, wherein first magnetic force (F1) and second magnetic force (F2), which are generated by the first magnetic flux and the second magnetic flux, respectively, are mutually overlapped and offset by the conversion of the second magnetic force, and the die and the punch approach and are separated from each other to shape the sheet. Accordingly the punch perform reciprocal motion with a simple structure by overlapping and offsetting the first magnetic force from the first magnetic unit and the second magnetic force from the second magnetic unit based on the conversion of the second magnetic force, and making the punch and the die approach and be separated from each other to shape a sheet. Therefore, production costs can be reduced and maintenance of the apparatus is easily performed. Further, by preparing the second magnetic unit as a solenoid to control strength of input alternating currents and frequencies, the size of punch pressing power and a pressurizing period can be easily controlled. The punch does not physically supported and fixed by a separate punch supporting unit, thereby preventing reduction of a service life of a sheet forming apparatus due to the accumulated fatigue load to the punch supporting unit according to the reciprocal motion of the punch.
