Embodiment 1-47

[0064] Examples 1-47 respectively provide the preparation method of the new superalloy regulator.

[0065] The preparation method of the novel superalloy regulator specifically comprises the following steps:

[0066] (1) Preparation of low-oxygen metal powder: using hydrogen to reduce the metal powder to obtain low-oxygen metal powder;

[0067] (2) Preparation of feeding material: uniformly mixing the low-oxygen metal powder prepared in step (1) with a binder to form feeding material;

[0068] (3) injection molding: the feeding material that step (2) is made is injected in the mold cavity, forms injection base;

[0069] (4) Catalyzed degreasing: the injection base prepared in step (3) is subjected to catalytic degreasing to form a degreased base;

[0070] (5) Sintering: sintering the degreased body prepared in step (4) in a vacuum environment or a protective atmosphere to obtain a sintered body;

[0071] (6) heat preservation and pressure preservation: the sintered billet o...

Abstract

The invention relates to the technical field of automatic rifle regulators, and particularly discloses a novel regulator and a preparation method thereof. The preparation method comprises the steps of: preparation of low-oxygen metal powder, specifically, reducing metal powder through hydrogen, wherein the reduction temperature is 700-1000 DEG C, and the reduction time is 0.5-1 h; preparation of a feed; injection molding: injecting the feed into a mold cavity to form an injection blank, wherein the injection pressure is 80-200 MPa, and the injection temperature is 100-200 DEG C; catalytic debinding: carrying out 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. The invention also provides the regulator prepared by the method. The service life of the regulator is remarkably prolonged.

Description

technical field [0001] The present application relates to the technical field of automatic rifle regulators, more specifically, it relates to a novel regulator and its preparation method. Background technique [0002] 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. The regulator is different from the barrel, which is replaceable throughout the life of the weapon, while the regulator is not replaceable during the life of the weapon. Therefore, the service life of the regulator determines the service of the automatic rifle life. [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 subjected to chemical erosion caused by various gas components in the gunpowder airflow. When the ad...
