Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heat-

The present invention relates to a component fixing apparatus for a heat treatment, and more particularly, to a component fixing apparatus for a heat treatment capable of preventing damage to an aluminum component and minimizing a time required for arranging and removing parts, .

In general, a method called heat treatment is used to make aluminum a desired part of an aircraft component, where the aluminum is treated at high temperature and quenched in water or a dedicated water-soluble oil.

In this process, in order to minimize thermal deformation of the heat-treated aluminum parts and to heat several parts at a time, they are loaded into a rack using a wire made of aluminum or SUS (Steel Use Stainless) .

Conventionally, a method of hanging a wire by using a wire is mainly used. However, there is a problem that parts are shaken to the left and right while heat treatment is performed in the inside of the work, and parts are struck against each other.

In addition, since the wire is hooked to the hole formed in the component, the hole may be damaged during heat treatment inside the work or after the heat treatment / quenching is finished and the part is removed from the rack.

In order to prevent damage to the holes, when wires are bundled in other parts of the parts other than the holes, the wires are pressed against the material, and the pressed parts of the wires are left on the surface or edge of the material.

The problem with the conventional method is that, in the process of removing the last part and the process of injecting the freezer in the working process, when the aluminum part is subjected to solution treatment as an aircraft part, a part of 100ea to 150ea or more is unpacked (racking) and heat-treated inside the work. Heat-treated parts are stored in the freezer to maintain the heat-treated state.

At this time, the working time is determined from immediately after the quenching to the introduction into the freezer. In this process, since the parts are respectively hooked on the wires, the parts are manually removed from the rack, and the parts are put in the freezer within a predetermined time, so that the number of parts that can be heat-treated at one time is limited.
