<p>The present invention of an extrusion machine for forming prestressed concrete cored single slabs comprises the narrow slab extrusion machine and the wide slab extrusion machine, having the mechanism for cutting and core-plugging to cut molded concrete cored slabs into single sections and plug cores on both ends of the slab, with the wide slab extrusion machine being able to form several transverse ribs at the intermediate positions of the slab. The said mechanism comprises the cutting blade, blade cylinder, blade vibrator, supplement feed device, supplement feed plate, supplement feed plate cylinder, the hydraulic pressure station and the means for movement. The said extrusion machine is able to produce directly high quality prestressed concrete cored narrow and large size slab units.</p> |
