摘要： The invention relates to an actuator device comprising two drive units (10, 20) for an actuator output drive (24). The first drive unit (10) has a first piston chamber (11), a first piston (12) which can be moved in the piston chamber, and first hydraulic means (16, 17a, 17b, 18, 19) for displacing the piston (12). The second drive unit (20) has a second piston chamber (21), a second piston (22) which can be moved in the piston chamber, and second hydraulic or pneumatic means (26, 27, 28, 29) for displacing the piston (22). The second piston (22) is fixedly connected to the actuator output drive (24) and can be coupled to the first piston (12) with respect to thrust such that the second piston (22) can be displaced by the first piston (12) in a direction of extension (PI). The first drive unit (10) is designed for a greater thrust force than the second drive unit (20), whereas the second drive unit (20) is designed for a greater stroke speed than the first drive unit (10).

摘要： The invention relates to a forming machine comprising a shearing device for shearing a bar (2, 20). Said shearing device comprises a fixed blade (11) with a passage (111) for permitting the insertion of the bar to be sheared (2, 20) and a shearing part (12) that can be displaced forwards and backwards in relation to the fixed blade (11). The shearing part (12) comprises a first shear blade (121), which is used to shear a bar section that projects from the fixed blade (11) when the shearing part (12) is displaced forwards and a second shear blade (122), which is used to shear a bar section (201) that projects from the fixed blade (11) when the shear part (12) is displaced backwards. In addition, the forming machine comprises a disposal point (8), to which the second shear blade (122) transports all the bar sections (201) it has sheared as scrap sections. As the second shear blade (122) exclusively shears scrap sections (201), empty points in the forming stations and the associated disadvantages can be avoided.

摘要： The invention relates to a hydro-mechanical clamp comprising two displaceable die-block halves (M1, M2) and two pressure rams (S1, S2). A first hydraulic piston (K1) is mounted in an axially displaceable first hydraulic cylinder (Z1) and a second hydraulic piston (K2) in a second hydraulic cylinder (Z2) in a displaceable manner. The second die-block half (M2) is fixed to the frame and the second pressure ram (S2) is arranged on the second hydraulic piston (K2). According to the invention, the first hydraulic cylinder (Z1) is connected to a third hydraulic cylinder (Z3), in which a third hydraulic piston (K3) is mounted. The above engages with a fourth hydraulic piston (K4) which runs in a fourth hydraulic cylinder (Z4). The first hydraulic cylinder (Z1) is connected to the third hydraulic cylinder (Z3), such that pressure medium displaced from the first hydraulic cylinder (Z1) on a forwards displacement, flows into the third hydraulic cylinder and the third hydraulic piston (K3) displaces the fourth hydraulic piston (K4) in a forwards direction so that pressure medium is forced into the second hydraulic cylinder (Z2) and the second hydraulic piston (K2) is pressurised with the necessary moulding pressure and the pressure rams (S1, S2) move together.

摘要： A device for hot pressing workpieces, comprising a matrix (5), an ejector (7) associated therewith that can move outwards and inwards and a pressure ram (1) that can move forwards and backwards. The ejector (7) is joined to a displaceable control piston (8) arranged in a pressure chamber (28). A liquid can flow out of the pressure chamber (28) via an exit hole (28) and a discharge line (23). A throttle (25) is arranged in the liquid discharge line (23) in order to retard the liquid as it flows outward and delay the extended ejector (7) as it is pushed back by the advancing pressure ram (1) in such a way that a workpiece (4) arranged between the ejector (7) and the pressure ram (1) is upset outside the matrix (5) and descaled.

摘要： The invention relates to a multistage metal-forming machine tool in which an apron (6) is screwed onto a pressing saddle (2). The apron (6) comprises six long-drawn tightening cams (62) which are arranged on the upper end of the apron and which are distributed over the width thereof. Four tightening tabs which project upward are placed on the lower end of the apron. A tool combination block (4) having a wedge-shaped supporting plate (42) is hung in the apron (6). Four tightening tabs (41) are configured on the upper end of the supporting plate (42) and are distributed over the width thereof, and four tightening cams are configured on the lower end. The tightening tabs (41) of the tool combination block (4) are hung over the tightening cams (62) of the apron (6), and the tightening cams (62) of the tool combination block (4) are inserted between the tightening tabs and the main part of the apron (6). A tightening force which is generated by two tightening devices (8) acts in a vertical direction toward the tool combination block (4). Said tightening force effects a tensioning of the tool combination block (4) and of the pressing saddle (2) in a horizontal direction.
