Japanese Patent JPH0716895
Kind Code:
B2
Abstract:
1. An arrangement comprising a carrier unit (3; 103) and an impacting unit (2; 102; 202) which is disposed inside the carrier unit, is connected thereto via resilient damping elements (31; 131; 231, 231a; 331, 331a) and contains a piston (26) adapted to make a traversing movement in a cylinder (25) in the direction of an anvil-like tool (1), characterized by the following features : - the carrier unit (3; 103) has two side cheeks (16; 116) interconnected via pins (20; 44) ; - the arrangement has pairs of shaped elements (20/29; 41/46; 52/56) ; - of each pair one shaped element (20; 41; 56) is associated with the carrier unit (3; 103; 203) and one shaped element (29; 46; 52) is associated with the impacting unit (2; 102; 202) ; - the shaped elements have a section having a central axis lying in a plane aligned perpendicularly to the axis of the impacting unit (2) ; - the shaped elements are in the case of all forces occurring between the impacting unit (2) and the carrier unit (3) maintained at a distance in the direction of the axis of the impacting unit (2) upwards and downwards and, at least in connection with a further pair of shaped elements, in directions aligned transversely of the axis of the impacting unit (2) by resilient material of damping elements (31; 131; 231, 231a; 331, 331a), such damping elements being positively or non-positively connected to the shaped elements.
