Know a little bit of people should know, unprocessed aluminum hardness is low, and mechanical automation equipment, assembly line workbench are used in aluminum profiles, then how to do aluminum profiles to withstand the load and not deformed? In fact, people who do extruded aluminum profiles know that profiles in the case of bending scrapped is not worth it, but also should not happen, but also can be avoided! So, how to reduce or avoid scrapping due to bending?
1, extrusion aluminum profile straightening can play what role: eliminate the metal stress generated in the extrusion process, control the size of the aluminum profile.
2, extrusion straightening: straightening is a very serious part of the aluminum profile caused by bending, straightening workers must pay attention to the strength used to straighten, the force is too large may produce deformation of the aluminum profile, closing, orange peel, etc., the force is too small will produce profiles can not be straightened, resulting in bending.
3, extrusion framing: this link is also very important, after sawing the length of the fixed feet, aluminum profiles should be framed, then framing workers should pay attention to: this material is big material or small material, is the material with a tube or plane die pulled out of the material? Generally speaking, large materials and materials with tubes to lift the two ends of the frame is not easy to cause bending, but small materials and plane mold pulled out of the material, lift the two ends is easy to cause bending, then it should be from the two ends to the middle of the close to lift the material for framing. But there are profiles even if this does not work, for example: louver, window, gland, etc., it is necessary to put this kind of material on the profile has been aging and then lifted to the frame.
4, surface treatment on the frame: billet by aging, the hardness has reached the standard, aluminum profiles are not so easy to become bent, but on the frame should still pay attention to the two ends of the lifting material, try to avoid the upper and lower fluctuations in force, fluctuations in force will be aging aluminum profiles have caused a certain degree of bending.
