The invention provides a hot forming tool of a
titanium alloy thin-wall part, comprising five parts, namely stretching equipment, a mould device, a blank, a power supply
system and a
temperature control system, wherein the mould device is arranged on a central worktable of the stretching equipment; the blank passes through a side wall crack of the mould device; an insulating and heat-insulation
cushion layer is used for insulating the blank, a clamp of the stretching equipment, the surface of a mould and a tool of the mould; the power supply
system is switched on to electrify an
electrode clamping plate and generate a current in the blank; the blank is heated and the temperature of the blank is measured and controlled by the
temperature control system; and after the temperature of the blank reaches a target temperature, the part is formed on the surface on the mould by the blank in an adhered manner through carrying out hot
forming processes successively including stretching, covering, stretching, heat preservation and
creep deformation and the like on the stretching equipment. A
machining method of the hot forming tool of the
titanium alloy thin-wall part comprises eight steps. According to the invention, the
heating efficiency, the
process integration, the material formation and the formation precision of the
titanium alloy thin-wall part in manufacture are greatly improved, so that the hot forming tool of the
titanium alloy thin-wall part and the
machining method of the hot forming tool have a practical value and a popularization value.
