The invention discloses a formation machine and a clamp assembly.The clamp assembly comprises a front support turnplate, a rear support turnplate, at least two clamps, a roller component and a pressure buffering component.In the process of hot pressing or cold pressing of one time, the clamps can accommodate cells, so that working efficiency and productivity of the formation machine are guaranteed; the clamps are arranged along the circumferential direction of the front support turnplate and the rear support turnplate, and the front support turnplate and the rear support turnplate can rotate around own axes so as to drive the clamps to rotate around the axes of the same for switching working positions.Compared with a mode that the clamps are arranged horizontally in the prior art, the formation machine has the advantages that space in the vertical direction of the formation machine is utilized effectively, area occupied by the formation machine in the horizontal direction is reduced, and size of the formation machine is effectively reduced, so that plant area occupied by the formation machine is reduced; a pressure buffering component can buffer squeezing force provided by the clamps, so that product protection effect is realized.
