Embodiment 1-35

[0063] Examples 1-35 respectively provide the preparation methods of superalloy regulators.

[0064] The preparation method of the superalloy regulator specifically comprises the following steps:

[0065] (1) Electrode casting: use vacuum induction melting technology to cast superalloy to form electrodes;

[0066] (2) Preparation of superalloy powder: using an argon atomization process to make the electrode prepared in step (1) into superalloy powder;

[0067] (3) Preparation of feeding material: uniformly mixing the superalloy powder and binder obtained in step (2) to form feeding material;

[0068] (4) Injection molding: the feeding material prepared in step (3) is placed in a powder injection molding machine, and injected into the mold cavity to form an injection blank;

[0069] (5) catalytic degreasing: carry out nitric acid catalytic degreasing to the injection base that step (4) makes, form the degreasing base;

[0070] (6) Sintering: sintering the degreased body prep...

Abstract

The invention relates to the technical field of automatic rifle regulators, in particular to a superalloy regulator and a preparation method thereof. The preparation method comprises the following steps: casting of an electrode, wherein the casting temperature is 1400-1500 DEG C; preparation of superalloy powder; preparation of a feed: uniformly mixing the superalloy powder and a binder to form the feed; injection molding: injecting the feed into a mold cavity to form an injection blank; catalytic debinding: carrying out nitric acid catalytic debinding on the injection blank to form a debound blank; sintering: sintering the debound blank in a vacuum environment or a protective atmosphere to obtain a sintered blank, wherein the sintering temperature is 1150-1300 DEG C, and the heat preservation time is 3-6 hours; and heat preservation and pressure maintaining: placing the sintered blank in a high-temperature and high-pressure environment, and carrying out heat preservation and pressure maintaining treatment, wherein the treatment time is greater than 3 hours. The invention also provides the regulator prepared by the preparation method. The service life of the regulator prepared by the preparation method is remarkably prolonged.

Description

technical field [0001] The present application relates to the technical field of automatic rifle regulators, and more specifically, it relates to a superalloy regulator and a preparation method thereof. Background technique [0002] Common ways for automatic rifles to be automatic include recoil and gas-guided. Among them, the automatic mode of the gas-guided type is to push the piston by shunting part of the gunpowder gas to realize automaticity. In the gas-guided automatic rifle, the part used to adjust the amount of diverted gas is a regulator, and the regulator is provided with a regulating hole for the passage of gunpowder gas. [0003] During the use of automatic rifles, the adjustment hole on the regulator will not only be washed by high temperature, high pressure and high speed brought by the gunpowder combustion airflow, but also be chemically corroded by various gas components in the gunpowder airflow. The regulator is different from the barrel. The barrel is rep...
