How aluminum extrusion works
The basic process and principles of aluminum extrusion:
Heating the aluminum alloy billet to an appropriate temperature (generally 350~500℃) makes it have sufficient plasticity.
The heated billet goes into the container of the extruder and the active part of the extruder (usually a plunger or screw) subjects it to high pressure.
The blank passes through the extrusion hole of the die under pressure to form the required aluminum profile.
After extrusion, aluminum profiles undergo post-processing such as traction, cooling, and cutting to ensure their size, shape, and performance.
Classification of Aluminum extrusion press machine:
Aluminum extrusion can be direct or indirect, depending on the extrusion direction.
Direct extrusion means that the movement direction of the active part and the blank is the same as the extrusion direction of the aluminum profile.
It also goes by the name of forward extrusion or forward extrusion.
The advantages of direct extrusion are simple equipment structure and high production efficiency.
The disadvantages are large extrusion force, high friction, high energy consumption, and poor surface quality.
Indirect extrusion means that the movement direction of the active part and the blank is opposite to the extrusion direction of the aluminum profile.
It also goes by the name of reverse extrusion or backward extrusion. The advantage of indirect extrusion are small extrusion force.
Low friction, low energy consumption, and good surface quality. The disadvantages are complex equipment structure and low production efficiency.
Main parameters and influencing factors of Aluminum extrusion press machine:
The main parameters of aluminum extrusion include extrusion speed, extrusion temperature, extrusion ratio, extrusion force, extrusion hole shape, etc.
These parameters determine the quality and performance of aluminum profiles.
Factors affecting aluminum extrusion include the composition and state of the aluminum alloy.
The size and shape of the blank, the design and manufacturing of the mold, and the selection and use of lubricants.
Post-processing conditions and methods, etc.
These factors need to be based on specific process requirements and Conditions are optimized and controlled.
Aluminum extrusion press machine components and functions
The main components of an aluminum extrusion press:
Mechanical part, hydraulic part, and electrical part.
The mechanical part is the main body of the aluminum extrusion press machine, including the frame, and container.
Active parts, molds, tractors, cutting machines, etc., and is responsible for realizing the basic movements and functions of aluminum extrusion.
The hydraulic part is the power source of the aluminum extrusion press machine, including oil pumps, cylinders, valves, pipelines, etc.
And is responsible for providing and controlling the pressure and flow required for aluminum extrusion.
The electrical part is the control system of the aluminum extrusion press machine, including motors, sensors, switches, instruments, controllers, etc.
Which are responsible for controlling and regulating various parameters and processes of aluminum extrusion.
The structure and function of each part:
The frame is the main supporting structure of the aluminum extrusion press machine.
Which bears the extrusion force and reaction force to ensure the stability and rigidity of the extrusion machine.
The rack is generally made of steel or welded steel plates and comes in horizontal and vertical forms.
The container is the main working part of the aluminum extrusion press machine.
To achieve extrusion, it accommodates and fixes the blank and cooperates with the active part.
The container, which has heating and lubricating devices inside, and sealing and connecting devices on the outside, is made of steel castings or steel forgings.
The active part is the main power component of the aluminum extrusion press machine.
To apply extrusion force to the blank and push the blank through the die, it uses the active part.
The active part, which has two forms: single-acting and double-acting, is generally composed of a plunger or screw driven by a hydraulic cylinder or motor.
The mold is the main forming component of the aluminum extrusion machine.
To determine the shape and cross-section of the aluminum profile, it uses molds.
Molds, which are generally made of high-strength and highly wear-resistant steel, have two forms: fixed molds and variable molds.
The tractor is the main post-processing component of the aluminum extrusion machine.
To ensure the speed and direction of their extrusion, it pulls and guides aluminum profiles.
Traction machines have motors, reducers, chains, clamps, etc. as their components.
And have two forms: synchronous traction and asynchronous traction.
The cutting machine is the main post-processing component of the aluminum extrusion machine.
It uses cutting machines to ensure the extruded length and quantity of aluminum profiles.
Cutting machines, which are generally composed of motors, blades, cylinders, sensors, etc., have two forms: flying shear type and fixed type.
Mold design and manufacturing:
The design of the mold is a key link in aluminum extrusion.
It needs to consider the shape, cross-section, size, tolerance, surface quality, and other requirements of the aluminum profile.
As well as the characteristics of the aluminum alloy, extrusion conditions, mold materials, and other factors, using mathematical models.
Finite element analysis, computer-aided design, and other methods determine the structure, parameters, tolerances, etc. of the mold.
The manufacturing of molds is an important part of aluminum extrusion.
It requires the use of high-precision machine tools, cutting tools, measuring instruments, and other equipment.
According to the mold design drawings and technical requirements, mold processing, heat treatment, inspection, and trimming.
And other processes are carried out to ensure the quality of the molds. and performance.
