Problems solved by technology

It can be seen from the above that the vertical quenching method has the following weaknesses: 1. The head of the aluminum tube needs to be punched before quenching, and the head needs to be cut off after quenching. This processing method consumes manpower and hours and affects production efficiency and yield.
2. Due to the long heating time, the surface of the aluminum tube is severely oxidized after being placed at high temperature for a long time, resulting in blackening of the surface of the aluminum tube after quenching and large grains, which cannot meet the customer's surface requirements; 3. The vertical quenching furnace is bulky , heating to a certain temperature consumes a lot of energy. In order to save energy, it is not suitable for quenching small batches of products, and the loading and unloading operations are complicated.

Abstract

The invention discloses quenching equipment for Al-Mg-Si system aluminum alloy cold drawn pipes, and a quenching method employing the equipment. The equipment comprises a transmission system, and orderly connected components of a feeding stage, a horizontal heating furnace, a quenching system, and a discharging stage. The transmission system comprises a motor, a transmission mechanism and a carrier roller transmission chain. The carrier roller transmission chain sequentially penetrates the feeding stage, the horizontal heating furnace, the quenching system, and the discharging stage. Electric heating tubes are symmetrically arranged above and below the carrier roller transmission chain in the horizontal heating furnace. The electric heating tubes are arranged in parallel with carrier rollers. A loading zone, a heating zone, a quenching zone and a fetching zone of the aluminum pipes are positioned on a same horizontal straight line. The aluminum pipes are always in a moving state. With the friction forces between the aluminum pipes and the carrier rollers on the rotary carrier roller transmission chain, the aluminum pipes move forward. During the moving process, heating and quenching are completed, and the aluminum pipes are finally delivered to the fetching zone. Therefore, hole-drilling on the end of an aluminum pipe is avoided, and a purpose of continuous feeding and quenching can be realized. With the equipment and the method, the operations of loading and fetching are simple and convenient, and the energy consumption during a quenching process is low.

Description

technical field [0001] The invention relates to heat treatment equipment and a method for an aluminum-magnesium-silicon-based aluminum alloy cold-drawn pipe and belongs to the technical field of nonferrous metal pipe processing. Background technique [0002] Aluminum-magnesium-silicon-based aluminum alloy cold-drawn pipes for automobile connecting pipelines usually need to be quenched, but the current quenching method is mostly vertical quenching, and the equipment used for vertical quenching is a vertical quenching furnace. The disadvantage of the vertical quenching furnace is that the furnace body is very high, generally more than 10 meters, which has certain requirements for the workshop height of the factory. At the same time, it needs to install a special crane for product lifting. The furnace body is too high for maintenance of equipment. cause certain difficulties. The vertical quenching operation process is as follows: first drill a hole in the head of the aluminum ...
