Note :Direct extrusion process:
When the shape of the final product is determined and the appropriate aluminum alloy is selected, the manufacturing of the extrusion die has been completed, and the preparation for the actual extrusion process has been completed. The bar is then preheated and the extrusion tool is used. During the extrusion process, the bar is solid but has softened in the furnace. Aluminium alloy melting point is about 660 ℃. Typical extrusion processing process of the heating temperature is generally greater than 375 ℃, and depends on the metal extrusion conditions, can be as high as 500 ℃.
The actual extrusion process begins when the extrusion bar begins to apply pressure to the aluminum bar inside the ingot. The size of the extrusion pressure designed by different hydraulic machines varies from 100 tons to 15,000 tons, which determines the size of the extrusion products produced by the extrusion machine. Extruded product specifications are indicated by the maximum cross-sectional dimensions of the product and sometimes by the diameter of the external circle of the product.
When extrusion has just begun, aluminum rods affected by the reaction of the mold change is short, thick, until the expansion of the aluminum rods are constrained by the sheng ingot tube wall, and then, when the pressure continues to increase, the soft (still) solid metal have no place to flow, start from the mould forming hole squeezed out to the other end of the mould, this creates a profile.
When heated aluminum is extruded from the mold through the cylinder, the metal in the center of the rod flows faster than at the edges. As the black stripe in the illustration shows, the metal around the edges is left behind and removed as a residue.
The rate of extrusion depends on the alloy being extruded and the shape of the die exit hole. Hard alloys are used to squeeze complex shaped materials, which may be as slow as 1-2 feet per minute. Extruding simple shaped materials with soft alloys can reach 180 feet per minute, or even faster.
The length of the extruded product depends on the aluminum rod and the die hole, and a continuous extrusion can yield up to 200 feet of product. According to the latest forming extrusion, when the extruded product leaves the extruder, it is placed on the sliding surface (equivalent to the conveyor belt). According to the alloy, the extruded product is cooled in the following ways: natural cooling, air or water cooling and quenching. This is a key step to ensure the metallographic properties after aging. The extruded product is then transferred to a cold bed.
After quenching (cooling) the extruded product is then straightened and twisted by a stretcher or straightener (stretching is also classified as cold working after extrusion). Finally, the product is transferred to the saw cutting machine by the conveyor.
A typical finished product sawing is the sawing of the product into a specific commercial length. Circular saws are the most widely used saws today, like a rotary saw that cuts through a long piece of extruded material vertically. There are also saws cut from the top of the profile (such as electric miter saws). There is also a saw table, with a circular saw blade rising from the bottom to cut the product, and then the saw blade back to the bottom of the table for the next cycle.
A typical finished disc saw, usually 16-20 inches in diameter, with more than 100 carbide teeth. Large size saw blade for large diameter extruder.
The self-lubricating saw cutting machine is equipped with a system to deliver lubricant to the saw blade, which can ensure the best cutting efficiency and saw blade surface.
An automatic press holds the profiles in place for sawing, and sawing debris is collected for recycling.
