Abstract
A platen design is provided for a C-frame press whereby an un-stiffened platen column connected in series to the tie rod; therefore, the stiffness of the tie rod is reduced. The unique design improves the fatigue strength of the tie rod by moving the reinforcing webs away from the column and directly onto the platen main body portion.
Claims15
A platen member for use in a C-frame press assembly, said platen member comprising:
- a platen column having a central aperture and defining a column axial length, said platen column defining a press axis;
- a tie rod is adapted to pass through the aperture of the platen column;
- a platen body having a base portion and at least one web portion, the platen column is positioned on the base portion,
- wherein said at least one web portion is positioned around the column axial length and is not rigidly connected with said platen column along the column axial length, and wherein said at least one web portion is connected to said platen column only through said base portion to thereby reduce a platen column stiffness.
1 more element
A platen assembly for a C-frame press comprising:
- a hollow platen column through which a tie rod is adapted to pass;
- a platen main body including a base press portion and a plurality of platen webs integral with said base press portion, the platen column is positioned on the base press portion around said platen column, said platen webs being remote from said platen column and said platen webs are positioned around said platen column such that said platen webs do not connect directly with said platen column,
- wherein said platen column is adapted to be connected in series with said tie rod to thereby reduce a platen column stiffness, and wherein said platen webs are connected to said platen column only through said base press portion.
