First of all, check whether the oil pressure system leaks oil and whether the air pressure is normal. Check the transfer belt, cooling bed, storage bench for damage and scratched sections.

Before the drawing to confirm the length of the aluminum profile, and then pre-determined the elongation rate, determine the length of the stretching, that is, the main jaw movement position, usually 6063T5 stretching rate of 0.5% - 1%, 6061T6 stretching rate of 0.8% - 1.5%.

According to the shape of the aluminum profile to confirm the clamping method, large-section hollow profile can be inserted into the tensile pad, but try to ensure adequate clamping area. When the aluminum profile is cooled to below 50°C, open the tensile profile. When the profile is bent and twisted at the same time, it should be corrected after twisting and bending.

The first and second tests are performed to confirm whether the predetermined elongation and the clamping method are appropriate. Visually bending, twisting, checking the plane gap of the profile, flaring, and paralleling, if inappropriate, adjust the stretch rate appropriately.

When the normal stretch rate still does not eliminate bending, twisting, or geometric dimensions, the operator should be informed to stop squeezing.

Finally, the profiles on the cooling platform cannot rub against each other, collide, overlap and prevent rubbing.

As long as each operation is in accordance with the requirements, Xiaobian believes that everyone in the factory will produce high-quality aluminum profiles.
