PURPOSE: A cam type press system is provided to relieve contact noise and impulsive force with a cam slider by installing a hinge cam at an operating driver operating the cam slider. CONSTITUTION: In a cam type press system comprising an upper pad(7) mounted on one side of the lower part of an upper die(3), a fixing steel(9) directly supporting and fixing the upper pad(7) as well as a material pad(1), a driving slider(11) integrally consisting a forming cam(13) and having a first return means, a cam slider(23) operating the driving slider(11) through a first slide part(19) and having a second return means, and an operating driver(41) operating the cam slider(23) through a second slide part(39), the cam type press system further comprises a hinge cam(43) which is installed at the lower part of the operating driver(41) so that the hinge cam(43) is hinge mounted on a mounting frame(45) by inserting return members into the mounting frame(45) having a stopper(47), and which contacts a second slide part(39) of the cam slider(23) so that the hinge cam(43) slidingly moves the cam slider(23) by pushing the second slide part(39); and a roller bearing(49) which is mounted on a lower die(5) in the state that the roller bearing(49) contacts the hinge cam(43) at the lower part of the hinge cam(43) so that the roller bearing(49) cam operates the hinge cam(43) according to downward operation of the operating driver(41).
