The aluminum alloy stamping oil is finally right this time, and I will never stick to the mold anymore
June 24, 2022
In order to achieve the lightweight vehicle, more and more automotive factories (OEMs) began to stress the body pressure parts with 5000 and 6000 series aluminum plates. The extension depth of the typical interior parts is generally 100 to 200 mm. Using traditional oil lubricating aluminum plates, because of the delayed adhesion problem (Galling), the materials outside the mold port are difficult to pull in, and the problem of cracking of stamping parts is serious. The sticky mold also causes unsightly strains on the surface of the workpiece, like wolf claws scratched. If you want to make a large number of aluminum -board body stamping parts, you must pass the Galling Flame Mountain. For so many years for the development of aluminum alloy stamping oil, the problem of this sticky mold is one of the main problems that are very distressed. If it is still the same as in the past, aluminum stamping is still using non -professional aluminum alloy stamping oil such as traditional motor oil, emulsification solution, it is likely that the adhesive problem is likely to occur. The materials outside the mold port are difficult to pull in, and the problem of cracking of stamping parts is serious.
Last week, a client for aluminum stamping due to adhesion? Because their molds and mold materials have tried their best. Only the professional aluminum alloy stamping oil was used. Today, the effect of the use of the effect is not the same as the oil effect used before. The problem of adhesion is solved. The boss joked that the aluminum alloy stamped for so many years, and the oil was used to use it before. To completely solve the problem of adhesion, of course, it is not only as simple as punching oil with aluminum alloy, but also improves from the aspects of materials and molds. In terms of board, surface texture can be processed. For example, using spray, electric spark, laser, etc., micro -coarseization (capacity) treatment on the surface of fine rollers. Before entering the rolling machine, the surface is like pressing fingerprints, leaving countless microstnes. For the stamping process, these microstnes are countless aluminum alloy stamping oil storage pools. The mystery here is that when the plate with "micro -numb appearance" on the surface slides on the mold, more aluminum alloy punching oil can follow the deformation zone; the more contact pressure in the deformation area, the more the contact pressure of the deformation area, the crowded from the micro -storage pool, squeeze from the micro -storage pool. The more aluminum alloy stamping oil comes out. If the surface of the fine roller is not treated with micro -richer treatment, or the micro -pit on the surface of the hair surface is used for too long, it has decreased with oil. After entering the deformation area, when the aluminum alloy stamping lubricant is needed Oil -free, the problem of adhesion may happen. In terms of mold, use as much mold steel as much as possible. Some punch -cut edge molds are recommended to polish the side. For conditional suggestions, PVD coating can be performed. For specific aluminum materials, aluminum alloy materials, aluminum stamping processes, customized aluminum alloy punch oil.
