Abstract:
An elbow lever sheet metal cutting press equipped with a pressure medium cylinder drive located between elbow lever systems, which suspend the press ram from the press frame. Adjustable lateral guides are attached along the columns of the press frame. A partition wall is located between the press frame and the press ram. Also, a piston rod guide is attached to the partition wall. These structures ensure the straight movement of the press ram. The distance between the lower end of the partition wall and the press table is as short as possible to minimize frame vibration. The inclusion of a box girder and the partition wall keeps the press table horizontally and vertically rigid.
Abstract:
A notching machine comprising an upper notching blade removably carried by a vertical ram for shearing co-operation with a lower blade removably carried by a die plate on a work table. The ram is guided for reciprocal movement by a strong box-section ram housing secured to and extending beneath the table. The drive for the ram includes a shaft actually journalled by the ram housing itself so that notching loading is taken in a short, efficient, closed load path via the ram, the housing and the shaft. This also gives material economy, enhanced accuracy of mutual blade location, and permits a simple arrangement for blade interchangeability.
