The bending method of aluminum profile is commonly used, and the bending method varies with different equipment. There are also many methods for bending arc processing of aluminum profiles, including combination processing, roll processing, bending and forging, and stamping, and more commonly metal pressing. The current development of aluminum profile bending processing industry also promotes the continuous development of bending processing technology.
Aluminum alloy processing
1、 Steps of aluminum alloy processing:
According to different bending equipment, the bending methods of aluminum profile bending arc are divided into manual bending and machine bending. Bending machine is divided into coreless elbow and cored elbow; Manual bending is suitable for small batch production, because the operation does not require professional equipment, the bending device is relatively simple, the cost is relatively low, but the labor productivity is low and the strength is high. There are five common methods for arc bending and stretch bending of aluminum profiles:
1. Stamping method: use the tapered core to expand the pipe end to the required size and shape on the punch.
2. Bending forming method: There are three common methods, one is stretching method, the other is stamping method. The third is roller method, which has 3-4 rollers, two fixed rollers, and one adjustment roller. The fixed roller pitch is used for adjustment. The finished aluminum profile is bent.
3. Bulging method: one is to put the rubber into the tube and compress it with a punch to make the tube protrude and form. The other method is hydraulic bulge forming. Fill the middle of the aluminum profile with liquid, and then the liquid pressure will bulge the bent tube into the desired shape.
4. Forging method: use a forging machine to punch out one end or part of the pipe to reduce the outer diameter.
5. Rolling method: usually no mandrel is required, and it is suitable for the inner round edge of thick wall pipe.
Processing of aluminum alloy parts
2、 Process type of aluminum alloy processing:
Aluminum alloy can be obtained by adding other metals, such as silicon, iron, copper, aluminum, etc. It has the characteristics of low density, high strength and corrosion resistance. Its light weight and strength make the aluminum profile suitable for the manufacturing of various parts. What are the processing technologies of aluminum alloy?
1. Aluminum alloy stamping process:
Stamping is a kind of forming method. The plates, strips, tubes and profiles are applied externally by using a pressing machine and a mold to deform or separate them plastically, so as to obtain the required shape and size. Stamping is a process of adding metal to product parts with fixed shape, size and performance by using ordinary or special stamping equipment to directly bear the deformation of the die. The three key elements of stamping are sheet metal, die and equipment. Forming is a kind of cold deformation plus cold stamping, also known as cold stamping or sheet metal stamping. This is the main method of adding ⾦ to ⾦ plastics.
2. Aluminum alloy precision casting processing:
Investment casting is a special kind of casting. Generally, parts obtained by this method do not need to be added. Such as investment casting, die casting, etc. The general method is: first, according to the product requirements, design and manufacture ⼀⼀⼩⼩⼩⼩⼩⼩⼩⼩⼩⼩⼩⼩⼩⼩⼩⼩⼩⼩⼩⼩120; Repeat the process of painting, sanding, hardening and baking the wax mold; Dissolving and dewaxing the inner wax mold to obtain a mold cavity; Bake and shape to make it have enough strength; Pour the required ⾦⾦⾦⾦⾦⾦⾦⾦⾦⾦⾦⾦⾦⾦⾦⾦⾦⾦; Heat treatment, such as heat treatment, cold heating, etc., It is imported according to product requirements.
