During the use of aluminum profile extrusion machines, kneading is a plastic processing method that applies external force to the metal billets placed in the container, causing them to flow out of specific mold holes and obtain the required cross-sectional shape and size. The aluminum profile extrusion machine is composed of a base, front pillar frame, tension column, kneading cylinder, and a hydraulic system under electrical control. It is also equipped with a mold base, ejector pin, scale plate, sliding plate, etc.
Aluminum profile extrusion opportunities can be divided into forward kneading method, reverse kneading method, (including plane deformation kneading, axisymmetric deformation kneading, usually three-dimensional deformation kneading) lateral kneading method based on the variety of metal in the aluminum profile kneading cylinder, stress-strain status, direction, smoothness, kneading temperature, kneading speed, type or structure of the mold, shape or number of blanks, and shape or number of finished products, Glass smooth kneading method, static liquid kneading method, continuous kneading method, etc.
The vast majority of hot deformation filter material manufacturers of aluminum profile extrusion machines choose the forward hot deformation kneading method to obtain aluminum materials that match the required cross-sectional shape through specific molds (flat mold, cone mold, and split mold). The forward kneading process is simple, the equipment requirements are not high, the metal deformation ability is high, the production scale is wide, the aluminum material function is controllable, the production flexibility is large, and the mold is easy to protect, maintain, and correct.
The defect is that there is a strong conflict between the inner and outer surfaces of the kneading cylinder and the aluminum material, which accounts for a relatively large proportion of kneading energy consumption. The conflict can easily cause the ingot inside the cylinder to heat up, increase the instability of the profile, damage the improvement of finished product efficiency, limit the kneading speed of aluminum and aluminum alloys, and increase the wear and service life of the kneading mold. The finished product arrangement is uneven in the front and back of the functional table.
1. Pure aluminum (L-series) corresponds to the world trademark 1000 series of pure aluminum, industrial pure aluminum, processability, corrosion resistance, surface treatment, and conductivity, but with low strength. It is used for household products, electrical products, pharmaceutical and food packaging, power transmission and distribution materials, etc.
2. Hard aluminum (Ly) corresponds to the world trademark 2000 AL Cu (aluminum copper) series alloy. Applied to large components and supports, with high Cu content and poor corrosion resistance.
3. Rust resistant aluminum (LF) corresponds to the world trademark 3000 AL-Mn (aluminum manganese) series alloy. The heat treatment cannot be strengthened, and the processability, corrosion resistance, and pure aluminum are appropriate. The strength is improved, and the welding function is outstanding. It is widely used in daily necessities, construction materials, equipment, and other aspects.
4. Special aluminum (LT) corresponds to the world trademark 4000 AL-Si (aluminum silicon) series alloy. Mainly based on welding materials, with low melting point (575-630 degrees), good fluidity and other characteristics.
5. Rust resistant aluminum (LF) corresponds to the world trademark 5000AL-Mg (aluminum magnesium) series alloy. Heat treatment cannot strengthen, but corrosion resistance, weldability, and surface gloss can be achieved. By controlling the Mg content, alloys with different strength levels can be obtained. Less used for decorative materials and equipment. Used for ships, vehicles, and construction materials. High for ships, vehicles, Chemical plant welding components.
