Description

Technical Field

[0001] The utility model relates to the technical field of workpiece quenching, in particular to a workpiece quenching device. Background Art

[0002] In the prior art, aluminum alloy has a low density and high strength, and its corrosion resistance and processing performance are also relatively good. It can meet the quality requirements of safety, economy, environmental protection and other related aspects of aircraft structural design. Therefore, aluminum alloy is now widely used in the field of aerospace and is the main structural material with the largest consumption on civil aircraft. Among them, aluminum alloys of the 2XXX, 7XXX and other series can be heat treated to strengthen the aluminum alloy. Specifically, they can be strengthened by solution quenching and aging heat treatment and then used. Among them, solution quenching mainly dissolves solutes such as Cu, Mg, Zn, and Si into the aluminum matrix uniformly by heating and heat preservation to obtain a supersaturated solid solution to prepare for subsequent aging treatment. Among the currently used civil aviation aluminum alloy workpieces, there are a large number of small-sized workpieces such as corner pieces, brackets, and connecting angles. There are no ear pieces, mounting holes, etc. on such workpieces. When quenching, not only is it difficult to mount and hang, but also the use of stainless steel wire for mounting and hanging will scratch the workpiece, and the use of aluminum wire for binding and hanging will also cause parts to fall off, which affects the quality of the workpiece, and the disassembly and assembly efficiency is low, and the mounting and hanging auxiliary materials are wasted. Therefore, how to ensure that such small-sized workpieces are not hung during the quenching process while ensuring the quality of the workpieces and reducing the cost of auxiliary materials is a problem that people in this field need to solve.
