A toggle-joint press or machine tool is easily adaptable to one of several common press drive mechanisms. Two forms of piston-in-cylinder (hydraulic or pneumatic) drives are disclosed as well as one form of a crank type drive.
Claims15
A press or similar machine tool, comprising a frame type tool carrier (1), a pair of identical buckling toggle-lever systems (9) connected to said frame type tool carrier and to a machine base (11) which slidingly supports said tool carrier and a drive system (2 or 3) operatively connected to cause the buckling and elongating of said toggle lever systems thereby reciprocating the tool carrier, and mounting means mounting said drive system exclusively in said tool carrier.
A press or similar machine tool, comprising a machine base (11), reciprocating tool carrier means (1) movably supported in said machine base (11) which guides the tool carrier means, two buckling, identical toggle-lever systems (9.1, 9.2) each including a buckling pivot joint (7) and first means operatively connecting the toggle-lever systems to said tool carrier means (1) and to the machine base (11) for moving the tool carrier means, drive means supported by said tool carrier means between said toggle-lever systems, and second connecting means for operatively connecting said drive means to said toggle-lever systems as the central drive for both toggle-lever systems which are arranged at a distance from one another in a free space of the tool carrier means, said first connecting means comprising fixed pivot joints (5) connected to the machine base (11), and movable pivot joints (6) movable in the stroke direction and hinged to the tool carrier means, said second connecting means comprising hingedly mounted intermediate members (10) pivotally securing the drive means to the toggle-lever systems.
