Abstract
A toggle press is provided with two levers (14, 16) which are pivotably connected by means of a joint (18), the first of which (14) is connected at its free end to a pressing tool (22) and the second of which (16) is rotation-resistantly mounted at its free end on a shaft (28) which can be rotated by a drive unit. The rotation-resistant connection between the second lever (16) and shaft (28) is releasable when the toggle lever reaches the extended position. The second lever (16) is disposed on a section of shaft (28) contrived as an eccentric cam (44).
Claims5
A toggle press comprising:
- first and second levers pivotally connected together by a joint,
- the first lever having a free end adapted to be connected to a pressing tool, and
- the second lever having a free end rotation-resistantly mounted on a shaft adapted to be rotated by a drive unit, the rotation-resistant connection between the second lever and the shaft being releasable, and the second lever being disposed on a section of the shaft contrived as an eccentric cam, and
- a pressure spring for fixing the second lever to the shaft in a releasably rotation-resistant manner, the pressure spring being disposed between a bearing of an arm mounted rotation-resistantly on the shaft and a bearing on a shoulder projecting from the second lever, such that the pressure spring presses the arm and the bearing on the shoulder apart with a pre-defined amount of compressive force.
