In the aluminum alloy forging process throughout the production process, which clean up and repair links occupy a more important position. This is because the aluminum material and the aluminum alloy itself is relatively small hardness, and poor mobility, it is easy to produce adhesion between the mold.
Then, after the aluminum alloy forging process, the resulting forgings may be folded, cracked or peeled and other defects. For these defects, if not clean up in a timely manner, then when the re-forging time will be further aggravated, and ultimately may lead to the entire forging scrap.
So, do you know exactly how to clean up? In fact, when the forgings are cleaned, we need to remove the burrs on the band saw or trimmer after the forging section in the aluminum alloy forging process. The forging is then placed in a pickling tank for cleaning.
It is important to note that after cleaning, check to see if it is clean. And then you can view the aluminum alloy forging process made of specific defects forging. Often, if it is a direct exposure to the surface of the forging defects, then you can use the cutter, wind shovel and other tools to repair the defects.
During the repair process, the transition area of the injured area and the surroundings should be taken into account to prevent folding at the time of the next forging. Generally in the aluminum alloy forging process, is in the cold conditions using trimming die trimming. If it is a large die forging, it should be used to cut the burrs with a band saw.
Finally, we should also remind you that if the use of aluminum alloy alloying degree is relatively high, then the use of aluminum alloy forging process after forging treatment, it should be cut as soon as possible. Otherwise it may precipitate enhanced phase, this time in the trimming, then may produce tear.
