The aluminum extruder is a plastic processing method that applies external force to the metal blank placed in the container to make it flow out of a specific die hole to obtain the required cross-sectional shape and size. Improving the production quality of aluminum extrusion presses begins with the first article inspection.
The quality inspection of the aluminum products produced by the aluminum extrusion press should be as follows:
After the aluminum extruder has ensured that all temperatures reach the standard and started production, the quality inspection should prepare the tools and drawings required for inspection, and compare the order to observe and measure the size, wall thickness, angle, and surface of the mold output, and reflect the measurement situation in time.
1. Stretching and straightening inspection when using aluminum extruder:
Straighten the profile in time after the temperature of the stretcher has dropped to avoid scuffing or scratches caused by the accumulation of the profile of the material bed; observe the appearance and size changes of the profile after straightening; and perform physical assembly of the profile that has an assembly relationship. Observe the stretched profiles to see if there is any bending or twisting. For special profiles and open profiles, the frequency of sampling should be increased.
2. When using the aluminum extruder, the material head should be sawed every 5 bars to observe whether there is die collapse.
Re-check the size every 10 bar sawing heads. Saw the frame according to the length required by the order, and frame the large material at the bottom, the small material at the top, the heavy material at the bottom, the light material at the top, the thick material at the bottom, the thin material at the top, the long material at the bottom, and the short material at the top. The framing method is carried out, and the framing profiles are checked for bubbles, slag inclusions, bending, twisting, scratches, bruises, and the unqualified profiles are sorted out for renovation and scrapped.
