Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy bar processing technology, and in particular to an efficient straightening device for aluminum alloy bars. Background Technology

[0002] The manufacturing process of aluminum alloy bars requires weighing high-purity aluminum ingots and the necessary alloying elements according to the formula, and then heating and melting them in a furnace. During this process, impurities and slag are removed through slag removal and other operations. The molten aluminum alloy is then transferred to a refining furnace, where it is refined and degassed through methods such as blowing, stirring, and adding refining agents. This further removes hydrogen, inclusions, and other impurities from the molten metal, improving the quality of the aluminum alloy. After the refined molten metal is allowed to stand for a period of time to allow impurities and gases to rise or be discharged, it is then cast to obtain aluminum alloy ingots. Casting methods include gravity casting, pressure casting, and centrifugal casting. The ingots undergo homogenization annealing to eliminate internal component segregation and residual stress, improve microstructure uniformity, and provide a good foundation for subsequent processing. The homogenized annealed ingots are heated to a suitable temperature and placed into the extrusion cylinder of an extrusion press. Pressure is applied through the extrusion rod, causing the aluminum alloy ingot to be extruded from the die orifice to form aluminum alloy bars of the required shape and size.

[0003] During extrusion, aluminum alloy billets are subjected to uneven pressure and friction in the die, resulting in residual stress inside the bar. If the stress distribution is uneven, the bar will bend in the direction of stress release after cooling. Many applications require the bar to have strict straightness; otherwise, it will affect the subsequent assembly accuracy. Therefore, it is necessary to straighten the aluminum alloy bars. However, in the existing technology, the aluminum alloy bars need to be manually supported at one end during the straightening process, which is prone to accidents and increases the workload of workers. Therefore, there is a need to propose an efficient straightening device for aluminum alloy bars. Utility Model Content

The rotation of each bidirectional screw 8 drives two corresponding threaded blocks 9 to move closer or further apart along the bidirectional screw 8, thereby driving the two straightening rollers 12 to move closer or further apart, thus adjusting the bar to the appropriate position. The distance between the material dimensions is such that the two straightening rollers 12 clamp the bar for straightening processing, while the right side of the bar is placed on the top surface of the adjusting frame 1801, so that the right end of the bar is in contact with the left side of the baffle 1806. Then, the motor 1802 is run, and the output end of the motor 1802 drives the double screw 1803 to rotate. The rotation of the double screw 1803 can drive the two threaded blocks 1804 to move closer to each other, so that the two clamping plates 1805 clamp the bar between them. Then, the motor 13 drives the threaded rod 14 to rotate. The rotation of the threaded rod 14 can drive the threaded block 15 to move left and right along the threaded rod 14, so as to transmit the bar to complete the straightening process.
