Abstract
The utility model provides a mechanical device of a rolled ring-shaped iron core. A machine frame is provided with a wall plate. The wall plate is provided with a rotating shaft through a bearing. The rear side of the wall plate is provided with a drive mechanism of the rotating shaft. The front side of the wall plate is provided with five guide blocks evenly distributed around the rotating shaft. The guide blocks are matched with pressure maintaining rods in a sliding mode. The outer side ends of the pressure maintaining rods are provided with pressure maintaining rod chain wheels. The top right corner of the front side of the wall plate is provided with a maintaining chain wheel. The starting end of a chain is fixed to the machine frame, and the chain sequentially winds around the five pressure maintaining rod chain wheels and the maintaining chain wheel. The tail end of the chain is fixed to a piston rod of an air cylinder. Retraction of the piston rod enables the chain to be tensioned. The chain is tensioned, so that the inner side ends of the pressure maintaining rods hold a die core of the rotating shaft tightly. In the work process, the five pressure maintaining rods evenly apply force on the periphery of the iron core so that a silicon steel sheet can be compacted in the rolling process, and therefore the circular degree of the iron core is ensured. As the five pressure maintaining rods are used at the same time, the span arc length among the pressing wheels of the pressure maintaining rods is short, the relative length of the adopted silicon steel sheet can be reduced, and therefore raw materials are saved beneficially.
