ABSTRACT:
A forming press that can perform multiple actuations within a single forming press, and which can be done accurately and with reduced overall machine size requirements. A first component side of the forming press can comprise multiple forming components, each of which may be separately actuated with respect to the other. Likewise, a second component side of the forming press also comprises multiple forming components that are independently actuable. The actuators of the press, as well as the multiple forming components, may lie on the same center line of the first and second component sides. By this construction, side loading is practically eliminated so as to produce consistent high quality formed parts and to enhance tool life. Preferably, guide surfaces for at least some of the rams of the forming press include at least a non-circular portion, and more preferably, plural non-circular portions that are flat portions so that needle bearings can be supported between the flat portions of the guides and corresponding flat portions of the rams. A method of forming a part, such as a head suspension, by a forming press having a first component side and a second component side, wherein multiple forming operations are actuated from at least one of the first and second component sides.
