Problems solved by technology

[0002] For pin parts used in aero-engines, in order to ensure the use requirements, it is necessary to adopt annealing technology at the end to ensure the hardness requirements. Due to the small size and large number of pins, the traditional induction annealing technology needs to manufacture precise induction coils and tooling. Therefore, it is not easy to manufacture, and the production efficiency is low. In order to ensure quality, save costs and improve efficiency, it is urgent to provide a tooling used for high-frequency annealing of pins.

Embodiment Construction

[0025] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0026] like Figure 1-2 As shown, a high-frequency annealing tooling for pins includes a pressing plate, a tooling bottom plate, a tooling cylinder, a high-frequency induction coil, and an adjustable platform, wherein the tooling cylinder is fixed on the adjustable platform; The mounting hole corresponds to the size of the pin. The pressure plate is placed on the bottom plate of the tooling and placed in the tooling tube together. The high-frequency induction coil is set on the upper part of the tooling tube. The bottom of the pressing plate passes through the pressing plate in reverse, and the tooling bottom plate is pushed against the head of the pin, and together with the pressing plate, the pin is fixed in the tooling barrel.

[0027] Further, the bottom of the tooling tube is closed, and water is filled inside, and when the p...
