Abstract

The invention provides an additional material rotating worktable with a circular cooling function. The worktable comprises a rotating worktable body, a rotating seal shaft and a base connected with anouter rotating driving device, the top of the rotating seal shaft is connected with the rotating worktable body, the bottom of the rotating seal shaft is connected with the base, a cooling loop allowing cooling liquid to flow is arranged on the rotating worktable, a cooling liquid inlet and a cooling liquid outlet are formed in the rotating seal shaft, the cooling liquid inlet communicates with the cooling liquid outlet through the cooling loop, the cooling liquid enters the cooling loop through the cooling liquid inlet, and carries out heat exchange with the rotating worktable body, the temperature of the rotating worktable body is reduced, non-contact workpiece cooling is achieved, and due to a shaft core and a shaft sleeve which can be mutually sealed and rotated, and an annular liquidinlet groove and an annular liquid outlet groove which surround the outer wall of the shaft core, the aim of stably inputting or outputting the cooling liquid to the cooling loop can be achieved.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing equipment, in particular to an additive rotary workbench with a circulating cooling function. Background technique [0002] When performing non-melting extremely inert gas shielded arc additive printing, the control system of the additive equipment controls the welding wire to continuously feed into the arc welding torch head, and the high-temperature arc between the arc welding torch head and the rotary table makes the welding wire melt on the rotary table. Print the bottom plate to form an additive printing layer, and form the workpiece after printing layer by layer. [0003] In this process of additive manufacturing, high heat input is likely to cause rapid heating of the workpiece. In order to ensure product quality, the workpiece needs to be kept in a relatively stable temperature range. The existing production process mainly uses the method of stopping and waiting for natural ...
