Abstract:
A shearing apparatus for shearing metal plates or the like includes a support frame on which a stationary blade is mounted to engage a plate to be sheared on one side. The other side of the plate is engaged during the shearing operation by clamping means mounted on the support frame for rocking movement about a first axis between an inactive and a clamping position, and movable blade means are mounted on the clamping means for rocking movement about a second axis transversely spaced from the first axis and moved by appropriate means connected thereto between an inactive and a shearing position to move thereby also the clamping means to the clamping position.
Abstract:
A device is disclosed for programming the terminal portion of the operative stroke of the tool in a machine tool equipped with hydraulic driving means. The stop motion comprises essentially a discharge valve responsive to a control wedge rigid with said tool and adapted to engage a stop member of which the position is determined in succession by the various adjustable studs carried by a rotary barrel. The barrel is simply laid upon a pair of cradle-forming rollers, at least one roller being driven from the means controlling the angular position of said barrel; if desired, a plurality of similar barrels corresponding to different predetermined programmes may be provided.
Abstract:
A shearing apparatus which includes a stationary rectilinear blade fixedly mounted on a stationary support and a movable rectilinear blade having a cutting edge including a predetermined angle with the cutting edge of the stationary blade. The movable blade is mounted for rocking movement about a pivot axis located in a plane which bisects the predetermined angle and which is substantially normal to a plane which includes the cutting edges of the two blades.
Abstract:
A punching machine with multiple fixed work stations, comprising a series of different punches disposed one after the other along common plane of alignment and opposite which the striking hammer can be displaced along this plane to be brought above the selected punch. This machine comprises a device for setting the position provided for the article to be punched, which comprises a setting templet and a control member, one of these members being fixed and the other associated with the movable support for the article to be punched, and the fixed member of this device is mounted on the frame of the machine in such a manner as to be able to be displaced parallel to the plane of alignment of the punches. This member is coupled to the movable striking hammer, or to the means for controlling the displacement of the same, along the plane of alignment of the punches, in such a manner that the displacement of this hammer in this direction causes an identical displacement of the fixed reference member of the setting device.
