In the figure, 1 is a processing table, 2A and 2B are processing receiving plates, 3A and 3B are processing disks, 4A and 4B are cylinder devices, 5 is an extrusion pin, 6 is a pin pushing device, and 7 is a press surface.

Claims (1)

[Scope of utility model registration request] It has a processing table and a pressing surface with a curved concave notch on the side so as to correspond approximately to one annular part of the S-shape, and is arranged point-symmetrically on the processing table while being pivotably supported for horizontal rotation. a pair of machining disks disposed near and opposite each of the machining disks on the machining table and eccentrically supported to be horizontally rotatable; a pair of cylinder devices connected to each processing disk to eccentrically rotate the processing disk;
A plurality of push-out pins for extruding the material are disposed so as to be able to come out and move out of the workbench at the lower position of the material in a press-formed state, and a pin pusher that supports the pins below the workbench in order to make the pins protrude above the workbench surface. S-ring press machine consisting of equipment.
