Aluminum alloy heat treatment frame

Abstract

The invention discloses an aluminum alloy heat treatment frame. The aluminum alloy heat treatment frame comprises a frame body; the frame body is composed of an upper part of an inverted circular truncated cone-shaped structure and a lower part of a cylindrical structure; an outer circumferential surface of the frame body is formed by a plurality of steel pipes arranged vertically, such that a plurality of rectangular holes are formed, and a plurality of round holes distributed irregularly are formed in the bottom of the frame body; the aluminum alloy heat treatment frame is simple in structure and relatively low in cost, and capable of remarkably improving the working efficiency; compared with the prior art, the aluminum alloy heat treatment frame has the following advantages that as the outer circumferential surface of the frame body is provided with a plurality of square holes that are distributed in two rows in the outer circumferential surface of the frame body, the square holes, due to a structure thereof, are beneficial to a cooling medium entering a frame body quickly, such that cooling speeds of various portions of a billet in the frame body are relatively uniform after the billet is immersed into the cooling medium; in addition, the cooling speeds all are able to reach a preset cooling speed, such that the quality of the treated billet is good and a relatively high yield can be achieved, and the production cost is thus reduced.

Description

technical field [0001] The invention relates to the field of heat treatment equipment, in particular to an aluminum alloy heat treatment material frame. Background technique [0002] At present, the frame body of the aluminum alloy heat treatment material frame in the prior art is used for the circular through hole for the cooling medium to enter and exit, but because the through hole is circular and the cooling medium has a certain surface tension, the rapid cooling At this time, the cooling medium is not easy to enter the frame through the through hole, so that the blank in the center of the frame cannot be in contact with the cooling medium in time, and the cooling rate of the central part of the frame and the nearby blank cannot reach the preset speed, which in turn leads to the quality of the blank. Unable to achieve the intended purpose, the quality is poor, which ultimately leads to low yield and high production cost. Therefore, the prior art aluminum alloy heat trea...

[0002] At present, the frame body of the aluminum alloy heat treatment material frame in the prior art is used for the circular through hole for the cooling medium to enter and exit, but because the through hole is circular and the cooling medium has a certain surface tension, the rapid cooling At this time, the cooling medium is not easy to enter the frame through the through hole, so that the blank in the center of the frame cannot be in contact with the cooling medium in time, and the cooling rate of the central part of the frame and the nearby blank cannot reach the preset speed, which in turn leads to the quality of the blank. Unable to achieve the intended purpose, the quality is poor, which eventually leads to lower yield and higher production cost

Therefore, the prior art aluminum alloy heat treatment material frame has the problem that the cooling medium is not easy to quickly enter the inside of the frame body.
