Aluminum alloy profile extrusion method and its working principle

According to the stress-strain state of the metal in the extrusion cylinder, the metal flow direction, the lubrication state, the extrusion temperature, the extrusion speed and the structure of the equipment, the type or structure of the tool and die, the shape or number of the billet, the shape or number of the aluminum alloy profile, etc., the extrusion molding methods can be divided into the following (Table 1) shown in a variety of methods; these classification methods are not static, many classification methods can be used as a subdivision of another classification method. For example, forward extrusion and reverse extrusion can be further divided into plane deformation extrusion, axisymmetric deformation extrusion, general three-dimensional deformation extrusion, etc. according to the deformation characteristics. Figure 2 shows several main extrusion methods widely used in the aluminum profile processing industry, namely forward extrusion, backward extrusion, pipe pressurization and continuous extrusion

What are the processing methods of aluminum alloy forgings?

The mechanical properties of aluminum alloy forgings can be improved by heat treatment and surface treatment to meet the requirements of the conditions of use. Different use environments also put forward clear requirements for the treatment of aluminum alloy forgings. Aluminum alloy forgings must also have certain mechanical properties, which is the basis for realizing the use value of aluminum alloy forgings. Today we will look at several commonly used stainless steel processing methods. It is precisely because of the different processing methods that different shapes of aluminum alloy forgings are formed. 1. Milling The milling cutter rotation is the main movement, and the aluminum alloy forgings and milling cutter are the feed movement. Milling is one of the main machining methods for flat surfaces. When milling, the rotation of aluminum alloy forgings and table milling cutters is the main movement. 2. Broaching Under the action of tensile force, the broach is used for axial movement to machine the inner and outer surfaces of aluminum alloy forgings. Using a multi-tooth broach, the extremely thin metal layer is cut from the workpiece layer by layer, so that the surface reaches a higher A accuracy, so that the roughness value of the aluminum alloy forgings is smaller. 3. Drilling The drilling tool moves relative to the aluminum forging and is fed axially. The method by which a forge processes holes on aluminum alloy forgings. Drilling is the most basic hole processing method in the processing of aluminum alloy forgings. 4. Turning Aluminum alloy forgings take rotation as the main movement, and turning tools are the cutting method of feed movement. The main movement of turning processing in forging plants is the rotational movement of aluminum alloy forgings, which is especially suitable for the processing of aluminum alloy forgings such as rotating face wheels and shafts. The linear motion of the tool is the feed motion. 5. Grinding The abrasive rotates at a high line speed, and the forge works on the surface of aluminum alloy forgings. Tools that are usually processed using abrasives are called grinders. During the grinding process, the self-sharpening effect of the grinding wheel is the cutting edge of ordinary tools that other knives do not have. 6. Boring The main movement of cutting processing is the rotation of the boring knife, which is the cutting processing method of aluminum alloy forgings or the feed movement of the boring knife. Boring processing is mainly carried out on milling machines and boring machines. Boring is the drilling of stainless steel forgings for further processing. Boring can expand the aperture, improve accuracy, reduce surface roughness, and better correct the deviation of the original hole shaft. Boring can be divided into coarse boring, semi-fine boring and fine boring. 7. Planing Planers and aluminum forgings perform relatively linear reciprocating movements in the horizontal direction. Planer is one of the main methods of plane machining, and it is the most commonly used processing method for small batch production of aluminum alloy forgings. Common planer machines include bullhead planers, double planers and grooving machines. For the above commonly used processing methods, forges will adopt different processing methods according to the different shapes required to produce aluminum alloy forgings. There are many processing methods for aluminum alloy forgings. Although these methods differ in their treatment principles, they still have much in common. The difference is that the cutting movement form of aluminum alloy forgings is different. However, due to the different machines and tools used, they have their own process characteristics. and the scope of application.
