Workpiece carriers in the form of self-locking tongs are provided in a blasting machine having a blasting chamber, a charging station and a discharging station. The carriers are mounted overhung on individual support structures which are movable laterally outside the blasting chamber to transport workpieces within the chamber. Tongs comprising a support rod on the axis of rotation of the carrier, and a transverse gripper rod which is movable for clamping the workpiece, are particularly suitable for carrying cylinder block workpieces and for the charging and discharging operations. The machine may have several treatment stations which may be arranged in line or on a circle. Various drive means are described, as are means for recirculating the said support structures and means for blasting workpieces from below and from above.
A blasting machine having a blasting chamber which encloses at least one treatment station, a charging station before and a discharging station after the blasting chamber, and workpiece carriers which are mounted laterally at their one end in overhung relation outside the blasting chamber, the workpiece carriers being constructed as pairs of tongs and mounted overhung on supporting structures movable laterally of the blasting chamber, and wherein the tongs are held by a self-locking mechanism comprising a threaded spindle in the closed position.
A blasting machine having a blasting chamber which encloses at least one treatment station, a charging station before and a discharging station after the blasting chamber, and workpiece carriers which are mounted laterally at their one end in overhung relation outside the blasting chamber, the workpiece carriers being constructed as pairs of tongs and mounted overhung on supporting structures movable laterally of the blasting chamber, and wherein the tongs are supported by a hollow shaft which can be driven and which is guided with a sealing effect through a slot in the side wall of the chamber and which is arranged to be coupled at each treatment station with a stationary rotational drive means.
In a blasting machine of the type having a blasting chamber, at least one treatment station having one or more blasting turbines, a loading station preceding the blasting chamber, an unloading station following the blasting chamber, and workpiece carrying means, the improvement comprising:
In a blasting machine of the type having a blasting chamber, at least one treatment station having one or more blasting turbines, a loading station preceding the blasting chamber, an unloading station following the blasting chamber, and workpiece carrying means, the improvement comprising:
In a blasting machine of the type having a blasting chamber enclosing at least one treatment station having one or more blasting turbines, a loading station preceding the blasting chamber, an unloading station following the blasting chamber, and workpiece carrying means, the improvement comprising:
In a blasting machine of the type having a blasting chamber enclosing at least one treatment station having one or more blasting turbines, a loading station preceding the blasting chamber, an unloading station following the blasting chamber, and workpiece carrying means, the improvement comprising:
A blasting machine having a blasting chamber which encloses at least one treatment station, a charging station before and a discharging station after the blasting chamber, and workpiece carriers which are mounted laterally at their one end in overhung relation outside the blasting chamber, the workpiece carriers being constructed as pairs of tongs and mounted overhung on supporting structures movable laterally of the blasting chamber, wherein the supporting structure, including drive means for the tongs, is movable horizontally in the direction of an axis of rotation of the tongs and is arranged to be raised at the loading and discharging station.
