This utility model relates to the technical field of material feeding in hot
forging production, and in particular to an adjustable and standardized feeding device for a ring feeder. It includes a component mounting panel, a full-material sensing group, a side-adjustable bridge base, an outer
diameter adjusting blocking component, a material passing blocking gate component, a feeding mechanism positioning component, a feeding side width adjusting component, and an outer end fixing plate. The side-adjustable bridge base accommodates materials of different thicknesses, the outer
diameter adjusting blocking component and the material passing blocking gate component work together to
control material flow, and the feeding mechanism positioning component and the feeding side width adjusting component ensure stable material descent. This application can automate the feeding of various material specifications, significantly improving production efficiency and equipment versatility, and reducing labor and equipment costs.
