The invention discloses a temperature equalizing plate for a 3D glass hot bending machine, and a preparation method and application thereof. The preparation method of the uniform temperature plate includes the following steps: A. Use tungsten powder to prepare a tungsten slab: B. Perform the first rolling, multiple second rolling and annealing treatments on the tungsten plate in sequence to obtain a tungsten plate , Wherein the average grain size of the tungsten sheet is less than or equal to 90 microns, the HV10 Vickers hardness at 20°C is 400-450N, and the density is greater than or equal to 19.1 g/cm3; C. The tungsten sheet is subjected to mechanical processing and surface resistance Oxidation coating treatment. The uniform temperature plate prepared by the method of the present invention has the advantages of high thermal conductivity, high high temperature hardness, good high temperature oxidation resistance and long service life when used for 3D glass hot bending molding.
