Quenching device for aluminum alloy circular pipe

Abstract

The invention belongs to the technical field of aluminum alloy production equipment and particularly provides a quenching device for an aluminum alloy circular pipe. The quenching device comprises a solid dissolving chamber and a cooling chamber. A partition plate is arranged between the solid dissolving chamber and the cooling chamber. Multiple heating devices are arranged in the solid dissolvingchamber. Multiple water spraying devices are arranged in the cooling chamber. A roller cylinder is arranged on the inner wall of the cooling chamber and penetrates through the water spraying devices.According to the quenching device, by arranging the water spraying devices, the multiple water spraying devices in the horizontal direction can achieve multi-station quenching, quenching efficiency is high, when all the stations work, the water spraying devices on the adjacent stations are arranged in a staggered manner, the water spraying devices above and below can spray water to the dead angleportion between the two adjacent water spraying devices on a current supporting pipe, uniformity is good, the probability of deformation and breakage of the circular pipe due to uneven stress causedby heat expansion and cold shrinkage of metal is reduced, meanwhile, the water spraying devices can be folded upwards before spraying water, the tops of the water spraying devices can be stretched after cooling the circular pipe, the circular pipe can be taken out upwards conveniently, and friction between the circular pipe and the roller cylinder is reduced.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy production equipment, in particular to a quenching device for aluminum alloy round tubes. Background technique [0002] Most of the extruded aluminum alloys are heat-treatable and strengthened alloys. After these alloys are extruded, they undergo solution heat treatment and aging to increase their strength and obtain useful structures and properties. The remarkable feature of heat-treatable and strengthened aluminum alloys is that their main alloying elements The solubility in solid aluminum increases greatly with the increase of temperature. Solution heat treatment (or quenching) usually includes two steps, namely solution treatment and cooling. [0003] In order to ensure the quality of quenching, the existing round tube aluminum alloy quenching device usually uses a single round tube for quenching treatment, which has low efficiency, and in order to ensure the uniformity of quenching, it...

Problems solved by technology

[0003] In order to ensure the quality of quenching, the existing round tube aluminum alloy quenching device usually uses a single round tube for quenching treatment, which has low efficiency, and in order to ensure the uniformity of quenching, it is easy to cause the round tube to be damaged by installing a ring-shaped cooling device. Uneven cooling. Due to thermal expansion and contraction of the hose, the stress of the round tube is uneven, and it is prone to deformation and fracture. At the same time, after the work is completed, the round tube is pulled out from the other side, causing friction with the cooling device, increasing In view of this, the invention provides a quenching device for aluminum alloy round tubes, which has the following beneficial effects:
