Efficient aluminum profile production line and production process thereof

Abstract

The invention relates to an efficient aluminum profile production line and a production process thereof. The efficient aluminum profile production process comprises the following process steps of aluminum bar heating, aluminum bar hot cutting, extrusion forming, air cooling, double-traction saw cutting, stretching straightening, sizing shearing and aging treatment. According to the efficient aluminum profile production line and the production process thereof, air outside a workshop flows through the surface of an aluminum profile at a high speed to achieve a rapid cooling effect, meanwhile, hot air is exhausted out of the workshop, noise and high temperature of the production workshop are reduced, power consumption of a cooling fan is reduced, in a sawing process, the aluminum profile is pressed and does not shake, the sawing section size of the aluminum profile is accurate and does not deform, the production efficiency is high due to alternate replacement and traction of two tractionwheels, and the aluminum profile is automatically aligned, so that straightening and stretching are automatically operated, materials are automatically fed and discharged during the aging treatment, and the whole production process is high in production efficiency, environment-friendly and safe.

Description

technical field [0001] The invention relates to a high-efficiency aluminum profile production line and its production process, belonging to the technical field of aluminum profile production. Background technique [0002] Aluminum profile is one of the most widely used light metal materials at present. After the aluminum rod is heated and extruded from the mold, it needs to go through air cooling treatment, traction sawing, straightening and stretching, aging treatment and other processes. [0003] In the existing aluminum profile production process: [0004] Air-cooling treatment generally adopts air outlets above and below the roller table that the aluminum profile passes through, and simultaneously blows air to the upper and lower surfaces of the aluminum profile for cooling. Since the upper and lower winds cancel each other out, the air velocity on the surface of the aluminum profile is not high, and the cooling effect of the aluminum profile is not good. It is often ne...

Problems solved by technology

[0004] Air-cooling treatment generally adopts air outlets above and below the roller table that the aluminum profile passes through, and simultaneously blows air to the upper and lower surfaces of the aluminum profile for cooling. Since the upper and lower winds cancel each other out, the air velocity on the surface of the aluminum profile is not high, and the cooling effect of the aluminum profile is not good. It is often necessary to add a cooling link in the subsequent process. In addition, the fan is directly installed in the workshop and the hot air is directly discharged, which generates huge noise and heat, and increases the environmental burden of the workshop;

[0005] The movement of the follow-up sawing is unstable, and the aluminum profile shakes during sawing, which may easily lead to quality problems such as large deviations in cutting dimensions and deformation of the cutting position; the single traction mode affects continuous extrusion and low production efficiency;

[0006] When straightening and stretching, because the length and position of the aluminum profiles on the conveyor belt are different, it is necessary to manually operate the straightening machine to sort and straighten and stretch. The efficiency of straightening and stretching is very low, which becomes a production bottleneck;

[0007] During the aging treatment process, the aluminum profiles cannot be operated automatically when feeding and discharging the aging furnace, which leads to low production efficiency and potential safety hazards
