Aluminum alloy section quenching device

Abstract

The invention belongs to the technical field of aluminum alloy processing and particularly discloses an aluminum alloy section quenching device. The device comprises a furnace body, and the furnace body comprises a quenching bin and a cooling bin; the quenching bin is internally provided with a first supporting plate, and the supporting plate is provided with a working platform; a heating unit isarranged at the top of the quenching bin; a second supporting plate is arranged inside the cooling bin, and a cooling unit is arranged at the upper end of the cooling bin; a locking unit is arranged on the second supporting plate; and the working platform conveyed in the quenching bin is tightly locked by the locking unit, so that the workpiece does not fall off when the working platform rotates.The aluminum alloy section quenching device has the advantages that by means of the heating unit, the heating area of a square pipe is effectively enlarged, so that the square pipe is more evenly heated; and a spraying nozzle arranged at the bottom end of a distributing panel of the cooling unit can move up and down, and the spraying nozzle can rotate, so that the spraying range of the spraying nozzle is wider, the cooling of the square pipe is more uniform, and the deformation or crack generated by the stress concentration and uneven cooling of the pipe is prevented.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy processing, in particular to an aluminum alloy profile quenching device. Background technique [0002] Aluminum alloy has low density, but relatively high strength, close to or exceeding high-quality steel, good plasticity, good processability, and excellent electrical conductivity, thermal conductivity and corrosion resistance. It has been widely used in aerospace, construction, automobiles, In various fields such as machinery manufacturing and ships, the usage is second only to steel. [0003] The hardness of the products made of aluminum alloy is very poor. In order to improve the hardness of the products, the products must be quenched; quenching is a heat treatment process in which the workpiece is heated to an appropriate temperature, kept for a period of time, and then rapidly cooled in the medium. To improve the strength, hardness, wear resistance, fatigue strength and toughness of ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a quenching device for aluminum alloy profiles, to solve the problem that the quenching range of the quenching unit is difficult to adjust during the above-mentioned background technology, and it is difficult to uniformly quench the aluminum alloy of the square pipe, so that the performance of the square workpiece is reduced; and cooling The cooling nozzles of the unit are all fixed. When the square pipe is cooling, the cooling range is uneven. Only the square pipe can be selectively cooled, which is easy to cause stress defects in the square pipe due to uneven cooling.
