Abstract (en)
[origin: EP1518667A2] A device is described which allows the stroke of a mechanical press to be adjusted, particularly during descent of the mobile part (6) and around its bottom dead centre. The device comprises, in combination with each other, a first kinematic mechanism (2) able to cause a shaft (3), for example a crankshaft, to rotate with a variable angular speed, a second kinematic mechanism (1) - driven by said shaft (3) - able to transmit the movement from said shaft (3) to the mobile part (6) of the press, a joint (4) able to uncouple the first kinematic mechanism (2) from said shaft (3) and means (5) designed to cause said shaft (3) to rotate with respect to the first kinematic mechanism (2), with the press at rest. A method of adjusting the stroke of a mechanical press by means of the device forming the subject matter of the present invention is also described.
