Automatic loading and unloading device for spherical fuel element pressing

The invention belongs to the technical field of industrial production automation of high-temperature gas-cooled reactor nuclear fuel element, and particularly relates to an automatic loading and unloading device for spherical fuel element pressing. The automatic loading and unloading device for spherical fuel element pressing comprises a core ball moulding material transfer system, a fuel-free zone moulding material transfer system, a final pressing and moulding transfer system and a mould cleaning system. According to the technical scheme, automatic operations of clamping a core ball mould, placing the mould to a powder receiving workstation, placing a secondary mixing workstation, pressing a core ball, cleaning the core ball mould, recognizing and positioning the core ball, placing a fuel-free zone, finally pressing upper and lower half moulds and the like in a high-temperature gas-cooled reactor spherical fuel element pressing process are achieved, the production efficiency of the pressing line is improved
