Summary:The invention provides an ultrathin hollow chain integrally-forming machine which comprises a feeding device, a forming device, a pushing device, a press fitting device, a first clamping device, a second clamping device and a welding device. The feeding device feeds gold pieces into the forming device to enable the gold pieces to be formed into chain link pieces. The pushing device pushes the formed chain link pieces into the press fitting device so that press fitting can be carried out on the chain link pieces. The first clamping device transfers chain links obtained after press fitting intothe second clamping device, and then the last chain link is installed into a bayonet of the former chain link to close the bayonet. The welding device carries out welding on the closed bayonet. According to the machine, the feeding device, a stamping die, the pushing device, the press fitting device, the first clamping device, the second clamping device and the welding device mutually cooperate and work to complete machin
