ã€China Aluminum Industry Network】 Aluminum extrusion die life has become the main bottleneck in the development of aluminum industry in China. The design and manufacturing cost of aluminum extrusion die accounts for about 20% of the total production cost. It is one of the key technologies for the aluminum profile extrusion industry with many variables and rapid development. It involves materials, design, manufacture, inspection, mold repair and management. And many other areas are also one of the areas with great potential for development.
How can we use this type of mold more reasonably, we can start from the following aspects.
(1) Strict implementation of aluminum production process regulations
Must be in strict accordance with the corresponding aluminum profile extrusion process, the middle of the aluminum bar furnace during the boot temperature is set at 530-550 °C, the outlet section temperature is set at 480-500 °C, the holding time should be sufficient to ensure that the aluminum rod is warm and Through the heart (that is, the heart and the surface are warm enough), to avoid the elastic deformation of the mold due to the uneven temperature of the aluminum rod (insufficient temperature of the heart part), thereby exacerbating the phenomena of “misalignment†and “different lengthâ€. Occurs, even plastic deformation of the extrusion die and scrapped.
(2) Ensure "Three Hearts"
The center of the squeeze tube, the center of the squeeze rod and the center of the die holder must be concentric visually, and no obvious eccentricity is allowed. Otherwise, the flow velocity of the product may be affected, and even the formation of the product or the length of the extruded product may be different. Large and unable to squeeze production.
(3) Reasonable selection of support pads
Must choose the appropriate size of the two-hole special support pads, in order to reduce the elastic deformation of the lower die, so that the extruded product shape stability, small size changes; but must be in the mold before the furnace to find a good double-hole support pad backup, so as not to die out Later, because it took a long time to find the support pad to cool the mold too much, a stuffy car appeared;
(4) Strengthen information feedback in aluminum extrusion process
A: Information feedback for extrusion die plugs
There are many reasons for the plug model, and it is generally difficult for a person who has not been specially trained to express clearly. It is better to go through the corresponding moderators to find out the reason and then find the reason.
B: Feeding molding feedback
In addition to having a clear die head with an extrusion die number, it is also necessary to identify the overall flow direction on the material head that is difficult for the material head to see, such as a, “cross-feed†(indicating that in the actual extrusion process is two The inside and the outside of the hole are caused by the slow outer side); b. "Discharge from the material" (indicating that in the actual extrusion process, the inside and the outside of the two holes are caused by the slow outer side); c. The "left long and right short" indicates that the left branch is long and the right branch is short. Also note the amount of difference between the lengths, because the distance from the interrupted saw to the discharge port is about 6 meters, so the “A meter/6 meter†form usually indicates that the difference between the length and the length is A meter for every 6 meters, so it is perfect and accurate. The expression is conducive to the correct judgment and maintenance of the repair personnel.
C: Information feedback for oversize error:
In the case of a normal out-of-feed molding but a poor size, a sample must be taken to complete the correct identification (extrusion mold number, discharge direction, size defects, etc.), and any one of the identification errors may result in Fix the wrong mold, so it must be highly noted.
Only such a complete use of information feedback is conducive to the correct judgment and maintenance of repair personnel, in order to improve the efficiency of mold maintenance, in order to reduce the number of mold repair and unnecessary test mode.
