Description
Technical Field
[0001] The utility model relates to the technical field of aluminum profile straightening machines, and particularly relates to a double-cylinder straightening machine with a pre-stretching function. Background Art
[0002] In the traditional aluminum profile processing process, the profiles usually need to be straightened by a straightening machine after extrusion molding to eliminate the internal stress of the material and improve its flatness and dimensional accuracy. The straightening machine is widely used in the straightening operations of various aluminum profiles due to its stable structure and large straightening force.
[0003] However, there are some problems in the operation of the existing aluminum profile straightening machines:
[0004] 1. Lack of an effective pre-stretching mechanism: The traditional straightening machine usually does not set a pre-stretching step before starting the straightening, which may lead to uneven stress distribution in the material during the straightening process and affect the quality of the final product.
[0005] 2. Straightening efficiency and accuracy problems: Due to the lack of pre-stretching, the material may not reach the ideal stress state when entering the straightening process, resulting in the need for multiple repeated straightenings to meet the requirements, reducing the production efficiency and processing accuracy.
[0006] 3. Limited adaptability to materials: Different materials and specifications of metal materials have different requirements for pre-stretching, while the existing straightening machines often lack the function of flexibly adjusting the pre-stretching force, restricting the application range of the machine.
