Aluminum rotating cup seat

The utility model relates to a component part of a rotating cup spinning machine, in particular to an aluminum rotating cup seat, which solves the problems of high cost, poor environmental protection performance, high roughness, easy fracture, poor impact vibration and torque load resistance performance, poor heat conduction performance, infirm bonding and poor braking performance of the existing rotating cup seat. The aluminum rotating cup seat comprises a rotating cup seat body and a braking seat hinged in front of the rotating cup seat body, wherein the rotating cup seat body is made of aluminum alloy. The aluminum rotating cup seat has a reasonable and reliable structural design, the surface roughness is reduced, the heat conduction performance is improved when the braking ability is ensured, in addition, the braking performance is ensured when the structure is firm, and the aluminum rotating cup seat has the advantages of low cost and simple structure and is convenient to process.
