Description

Technical Field

[0001] The invention relates to the technical field of straightening equipment, in particular to an aluminum profile straightening device with a heat-insulating function. Background Art

[0002] Aluminum profile straightening equipment is mainly used to correct the bending, twisting or other deformation of aluminum profiles caused by extrusion, heat treatment and other processes during the production process. The straightening equipment ensures the straightness and dimensional accuracy of the profile by applying mechanical force. Common aluminum profile straightening equipment includes the following: straightening machine, which applies continuous bending and reverse bending stress to aluminum profiles through a series of arranged straightening rollers or straightening wheels to gradually eliminate the bending and distortion of the profiles. Generally, multiple straightening rollers are used in two rows, upper and lower. The profiles are gradually straightened when passing between the rollers. A set of straightening wheels can also be used to correct the bending of the profiles by adjusting the pressure and position of the wheels; stretching straightening machine, which straightens aluminum profiles by applying axial tensile stress to them, and the stretching amount is generally between 0.5% and 3%; pressure straightening machine, which uses hydraulic or mechanical presses to apply pressure to aluminum profiles through upper and lower pressure blocks to gradually correct bending and distortion; straightening roller bed, which uses multiple sets of small-diameter straightening rollers to correct the straightness of the profiles by applying continuous bending in different directions; CNC straightening machine, which uses CNC technology to ensure high-precision straightening of profiles by precisely controlling straightening parameters. It has the advantages of high degree of automation, easy operation and strong adaptability. For aluminum profiles of various lengths and cross-sectional shapes, a more versatile roller straightening machine is generally used to straighten the aluminum profiles.

[0003] In the existing straightening process of aluminum profiles, in certain circumstances, in order to reduce the hardness and brittleness of the material and improve its plasticity, the aluminum profile can be heated to a temperature slightly higher than room temperature, generally 50-100°C, during the straightening process. This treatment method can reduce cracking or other defects that may occur during the stretching process without affecting the strength of the aluminum profile. However, the existing roller straightening machine cannot heat and insulate the aluminum profile, which makes the application scenarios of the existing straightening machine relatively limited.
