Abstract

The invention discloses a processing method for a high-tenacity metal embedded part in an iron casting, the embedded part and a brake drum. The processing method comprises the steps of: carrying out an anti-carburization treatment on the peripheral surface of the high-tenacity metal embedded part before casting the iron casting, wherein the anti-carburization treatment is to electrically plate nonferrous metals or coat an anti-carburization coating; an anti-carburization protective layer is formed on the peripheral surface of the high-tenacity metal embedded part main body; the anti-carburization protective layer is a plating layer made of the nonferrous metals, such as copper or nickel or a coating layer made of the anti-carburization coating; the brake drum comprises a brake drum main body and the annular high-tenacity metal embedded part combined with the brake drum main body through a casting way. The processing method for the high-tenacity metal embedded part in the iron casting, the embedded part and the brake drum have the beneficial effects of avoiding the casting being carburized in the casting process to keep the tenacity efficiently, improving tensile strength and fatigue strength of the iron casting, improving comprehensive mechanical performances and service life of the casting, and achieving long service life and high safety of the brake drum.

Description

technical field

[0001] The present invention relates to a strengthening technology of iron castings, in particular to a treatment method for high-toughness metal embedded parts in iron castings, as well as metal embedded parts in iron castings and manufacturing including the metal embedded parts drum. Background technique

[0002] Iron castings refer to mechanical parts formed by casting blanks made of cast iron and then machined, or mechanical parts formed directly by precision casting; they are often used as engine blocks, large and medium-sized hydraulic cylinder blocks, and large and medium-sized cylinder blocks. , Vehicle brake drums and equipment bed and other equipment basic parts. Brake drum, also known as brake drum, is an important security component for the safety of motor vehicles, especially trucks. Because it needs to form sufficient braking force with the brake shoe, it needs sufficient strength requirements and also has good wear resistance, so it is usuall...
