Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile processing, in particular to an aluminum profile stretching and straightening machine. Background Art

The above-mentioned clamping plate, worm and gear are installed. When the aluminum profile is clamped and fixed, the rotation of the No. 2 motor drives the worm to rotate, the rotation of the worm drives the gear to rotate, the rotation of the gear drives the tooth plate to move, the movement of the tooth plate drives the clamping plate to move, and the movement of the clamping plate clamps the aluminum profile in the clamp. However, the aluminum profile stretching and straightening machine in the above-mentioned document only stretches one side of the aluminum profile when stretching and straightening the aluminum profile, and the overall stretching force of the aluminum profile is concentrated on one end of the aluminum profile. A larger stretching force is required when stretching and straightening the aluminum profile, which makes it inconvenient to stretch and straighten the aluminum profile. At the same time, when the aluminum profile is stretched and straightened, the end of the aluminum profile will also have a certain curvature. After the clamping plate in the above-mentioned document positions the aluminum profile, as the aluminum profile is stretched, the bent position of the end of the aluminum profile may become straightened. At this time, the aluminum profile will be separated from the clamping plate, and the clamping effect of the aluminum profile is poor when the aluminum profile is stretched and straightened.
