DEVICE TO PRODUCE CIRCULAR WORKPIECES OF ABRASIVE DISKS ON RUBBER BOND

摘要

FIELD: machine building.SUBSTANCE: upper mandrel of the device is fixed on the press slide with the possibility of simultaneous translational and reciprocating movement. It is fitted by a roller mounted so that to be able of rotating in respect to its own axis with the roller length being equal to the diameter of the die ring cavity. The end surfaces of the roller are made rounded and with travelling arresters. A lower mandrel spring-loaded in respect to the die base is installed in the hole of a circular shedder.EFFECT: production of circular workpieces with equal density by the volume and minimal possible variations in thickness.3 dwg
