Technique treatment method for induction heating of special-shaped piece

Abstract

The invention relates to a technique treatment method for induction heating of a special-shaped piece, belonging to the technical field of induction heating treatment technique of automobile parts. The technique treatment method has the following technical process and steps: (1) selecting and using induction heat treatment equipment with corresponding frequency and power according to the shape and the technical requirements of the special-shaped piece; (2) designing an inductor according to the shape and the technical conditions of the special-shaped piece; (3) selecting a magnetizer with corresponding type and specification according to the frequency of the selected induction heat treatment equipment; (4) processing the magnetizer according to the inductor and the shape of the special-shaped piece; and (5) adding the magnetizer to the position needing magnetic fields to be concentrated so as to form a complete induction heater. Through he technique treatment method, a hardening layersimilar to the contour line of a part is obtained after induction heat treatment is carried out on the part. The technique treatment method not only ensures that the hardening layer of the small special-shaped piece meets the technical requirements, but also shortens heating time under the condition of constant power, reduces the energy consumption, and simultaneously reduces the electric field intensity and the magnetic field intensity with high-frequency radiation of an operation part to be below half of the national standard specified value.

Description

technical field [0001] The invention relates to a process treatment method for induction heating of special-shaped parts, belonging to the technical field of induction heat treatment process of auto parts. Background technique [0002] The heat treatment industry is accelerating the pace of industrial restructuring, developing advanced technology and energy conservation and emission reduction, transforming traditional heat treatment into modern heat treatment, and becoming a production-oriented service industry that is oriented towards intelligence, precision, economy and cleanliness. Because induction hardening has fast heating speed, high production efficiency, energy saving, no oxidation and decarburization of parts, small deformation, and no pollution to the environment, it meets the "3S" standard (Sure, Safe, Saving) and "3C" of modern industrial production. "Standard (Cool low temperature, Clean clean, Calm quiet) and other advantages, so induction hardening has been w...

AI Technical Summary

Problems solved by technology

At present, it is very difficult to solve the surface or local hardening of small and special-shaped parts of automobiles with traditional induction heat treatment technology. It is difficult to obtain uniform hardness and a hardened layer similar to the outline of the part. Therefore, most of them use carburizing or nitriding technology. deal with

However, the production cycle of carburizing or nitriding is longer than that of induction heat treatment, the energy consumption is higher than that of induction heat treatment, and the pollution to the environment is also greater than that of induction heat treatment.
