What Is The Extrusion Principle of An Aluminum Profile Extrusion Machine?

The working principle of the aluminum profile extrusion machine is as the name suggests, through extrusion, the aluminum profile is made into the desired product. So, do you know the extrusion principle of an aluminum profile extrusion machine? For aluminum profile extrusion machine products, the following introduction of Jiuying hopes to be helpful to you.

Aluminum Profile Extrusion Machine Principle

The so-called extrusion is a pressure processing method that applies pressure to one end of the billet placed in the container (extrusion cylinder) to form it through the die hole. In the production of pipes and profiles with complex cross-sections, extrusion is the only possible pressure processing method. Therefore, aluminum profile processing is achieved by extrusion. The realization of the extrusion method can be divided into two types: forward extrusion and reverse extrusion. 

During forward extrusion, the flow direction of the metal is the same as that of the extrusion rod, and its main feature is that there is a large external friction force between the ingot and the inner wall of the extrusion cylinder. In reverse extrusion, the metal flow direction is opposite to the extrusion movement direction, and its characteristic is that there is no relative sliding between the metal and the inner wall of the extrusion cylinder, and there is no external friction. The different characteristics of forward extrusion and reverse extrusion have a great influence on the extrusion process, product quality, and production efficiency.

Structural Principle of Aluminum Profile Extrusion Machine:

Usually, a complete aluminum profile extrusion machine system is mainly composed of three parts: mechanical part, hydraulic part, and electrical part.

1. The mechanical part includes the base, guide column (also known as pull rod), front beam plate (referred to as front plate), rear beam plate (cylinder seat), heat preservation seat (spindle seat), scissors seat, mold seat, upper and lower guide rail plates, and mechanical delivery Ingot device, extrusion rod base (butterfly head), extrusion rod and so on.

2. The hydraulic system consists of a main cylinder, auxiliary cylinder (fast side cylinder), locking cylinder (front plate cylinder), mold base cylinder, plunger pump (divided into the variable pump and quantitative pump), vane pump (divided into the single pump) Composition and multi-pump) combined pump), valve plate, valve (one-way valve, overflow valve, reversing valve, etc.), oil pipe, oil tank, and various hydraulic switches.

3. The electrical part is mainly composed of a power cabinet, operating table, PLC programmable controller, AC contactor, display screen, and so on.

The Role of The Main Components of The Aluminum Profile Extrusion Machine:

1. The machine base is the carrier of all functions including the machine base, and is a closed part that bears the extrusion force.

2. The main cylinder is a hydraulic working cylinder that generates extrusion force and is of plunger-type structure.

3. Guide pillars, also known as tie rods, the front plate, and the main oil cylinder are fastened together by four guide pillars with nuts to form a closed stress-bearing system to withstand the pressure of the hydraulic press when it is working. The middle plate part and the butterfly plate of the main cylinder move forward and backward guided by four guide pillars. Therefore, in addition to the force, the guide column also acts as a guide rail for the moving beam and the extrusion cylinder.

4. The butterfly plate is a part used to balance the weight of the protruding part of the main plunger and control the center of the extrusion shaft.

5. The insulation seat, also known as the ingot tube, is used to install the aluminum ingot billet and is a high-pressure constant temperature container.
