PURPOSE: A structure of cam for performing flange operation on panel using electromagnets is provided which enables the operation to be performed even in a small working space and easily extracts the panel without interference during extraction of the panel. CONSTITUTION: In a structure(100) of cam for performing flange operation on panel, the structure comprises a lower die cam base(10) on which a sliding hole(13) is formed; a lower die cam steel(30) which is slidingly mounted on the sliding hole, and on a front end of which a panel(11) that is a working object is rested; a cam housing(20) which is mounted on an upper part of the lower die cam base, and in which the panel is rested; a moving device(40) comprising a plurality of electromagnets and spring members installed in the sliding hole so that the cam steel is moved back and forth in the sliding hole through attraction between the electromagnets; and an upper die cam steel(53) for performing flange operation on the panel in the forward movement state that the cam steel supports the panel, wherein the moving device moves forward the upper die cam steel if it is necessary to perform flange operation on the panel and moves backward the lower die cam steel if it is necessary to extract the panel, and wherein the moving device comprises first electromagnet(41), second electromagnet(43), third electromagnet(45) and spring member(47).
