摘要： A punch which includes a notching tool and a separating which are adapted to punch at least one notch and a separating gap in each effective working stroke of the punch. A separating tool is formed by at least two independently disposed separating punches which are spaced from each other by a distance which is equal to or greater than a width of a web formed between two punched notches. Likewise, the notching tool may be in the form of two independent spaced notching punches.

摘要： An automatic numerically controlled slotting or notching press arrangement which includes a multi-armed feed and removing device having a turnstile or turntable which is selectively indexed or rotated so as to convey blanks to various processing stations. The feeding and removing device is adapted to transfer the blanks from at least one stack unloading station to a centering or aligning station, a locating or turning station, a processing station, a stator stacking station, and a rotor stacking station. A numerically controlled indexing unit (a clamping table for blanks to be processed) and a numerically controlled tool changing is provided. The stack unloading station and the rotor stacking station form the first and last processing stations and are linked by a conveying device which operates independently of the turnstile or turntable of the feeding and removing device.

摘要： A press drive with a central cam shaft actively connected through a connecting rod with a slide guided in a linear guide. Side bars are symmetrically articulated with respect to each other on the slide. Mass balancing weights are driven in opposed directions corresponding to reciprocating masses of the press, with the weights being connected with the slide by other linkages. Pairs of toggle joint linkages are disposed symetrically with respect to the cam shaft. The pairs of toggle joint linkages include a first almost horizontally disposed toggle joint linkage that is articulated on the respective side bars and presents a bearing point on the press frame. A second almost vertically disposed toggle joint linkage that is connected with the first toggle joint linkage and is articulated so as to be guided by the press frame on the mass balancing weight. A third almost vertically disposed toggle joint linkage is articulated on the punch through a transmission bar with the first and second toggle joint linkages and is braced in a direction of motion of the punch on the press frame.

摘要： An arrangement for an intermittent operation in a notching machine which includes a ram driven by way of a crank or eccentric drive which ram is articulated to a toggle joint. The notching machine has an operating cycle which consists of alternatingly successive notching and notch-free steps which is attainable by means of a cylinder-piston unit activatable pneumatically or hydraulically which unit is in operative connection with an eccentric supported on a pin with the eccentric being the central fulcrum of the toggle joint. A second toggle joint with a counterbalancing mass is diametrically opposed to the ram with the second toggle joint being articulated to the eccentric. The central pivot as well as the points of articulation of the toggle joints to the ram and counterbalancing mass are disposed substantially in one plane.
