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

This application relates to the technical field of automatic rifle regulators, and specifically discloses a new regulator and its preparation method; the preparation method is: preparation of low-oxygen metal powder: use hydrogen to reduce the metal powder, and the reduction temperature is 700-1000°C , the reduction time is 0.5-1h; the preparation of the feed; injection molding: inject the feed into the mold cavity to form an injection blank; the injection pressure is 80-200MPa, the injection temperature is 100-200°C; catalytic degreasing: inject The billet is degreased by catalytic degreasing to form a degreased billet; sintering: the degreased billet is sintered in a vacuum environment or a protective atmosphere to obtain a sintered billet; Placed in a high temperature and high pressure environment, treated with heat preservation and pressure; and the regulator prepared by the above method. The service life of the regulator of the present application is significantly extended.

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...
