Benefits of technology

The present invention is a heat treatment method and equipment for mass processing of components. It uses infrared heating to quickly and efficiently transfer heat to the targeted object. The equipment includes a chain conveyor with a pallet and a heating oven with infrared emitters and sensors. There is also a reflector unit with a housing that concentrates infrared radiation onto the components. The equipment has a cooling provision to prevent heat transfer to non-targeted regions. Overall, the invention increases the throughput of heat treated components.

Problems solved by technology

This characteristic of the process contributes to a complex equipment design, heavy and large equipment footprint and significantly higher energy consumption and cost per component in online mass production.

example

[0029]A sample processed components having undergone the above heat treatment method were measured in the lab for softening parameters. It was proven that components processed with the said method exhibit equivalent or better values and reduce the process cycle per component by up to 50%. The contribution of enhanced thermal penetration of infrared heat as designed for the above referenced equipment of the said invention thereby proves that this improved method not only delivers productivity and energy efficiency but also enhanced quality to the heat treatment process.

Abstract

Disclosed is heat treatment equipment and process that facilitates heat treatment process by introducing focused high intensity infrared heating to components on a conveyorized system for maximizing the throughput of heat treated components.

Description

FIELD OF THE INVENTION[0001]The present invention relates to the field of thermal processing or heat treating of parts and components made out of several materials for industrial and non-industrial use to achieve an objective such as pre-heating, stress relieving, hardening, softening, wear resistance, expansion shrink-fit and the like. More particularly, the present invention relates to an improved heat treatment method and equipment for mass processing of components and / or assembly of components thereby offering a high productivity and energy efficiency.BACKGROUND OF THE INVENTION[0002]Induction hardening or softening is one such widely used conventional heat treatment process that is most commonly applied to ferrous or metallic components with the objective of changing the surface properties of the component thereby enhancing wear, friction and fatigue resistance of the same. Common components include axles, gears, spindles, shafts, cam lobes, stamping, etc.[0003]Typically, the i...
