Aluminum Pipe Drawing Technology

Inside the aluminum tubing production procedure, cold drawn aluminum tube may be the most common one, this process since it is birth has created loads of industrial value, very suitable for the production of light weight aluminum tube, has been many manufacturers. Today let's check out the aluminum tube painting process.

Definition Of Aluminum Water pipe Drawing Technology

Aluminum tube drawing technology is a kind of plastic processing method, which uses the additional force to act to the front end of your drawn metal, and then pull the metal blank from the die hole in the section of the empty, so as to obtain corresponding shape and size belonging to the aluminum tube. Because drawing is usually done in a cold state, it is also referred to as cold drawing or wintry drawing.

During drawing, that aluminum tube will deform in addition to its original shape plus size will change. On the other hand, the volume of the actual aluminum tube is virtually constant During metal plasticity.

Not the same as extrusion, rolling, forging along with processing processes, the drawing process is realized by means of a pull force to the front end of that processed metal, which is known as drawing force. The ratio belonging to the drawing force to the cross-sectional area of the drawn metal along at the die outlet is called the machine drawing force, or your chance stress. The drawing stress must be less than the yield strength in the metal die, if enter stress is too significant, more than the yield strength on the metal die, can result in the aluminum tube appear thin neck, or even break.

Classification Of Metal Pipe Drawing Technology

Solid drawing mainly includes standard, profile, wire drawing; Hollow drawing mainly includes tube and shaped hollow drawing. Our common cold painting aluminum tube belongs to the latter.

Among them, you will discover the following methods intended for tube drawing.

Sinking painting

During drawing, no core head lies inside the billet, when i. e. no core scalp is drawn. The main purpose would be to reduce the diameter in the billet.

After drawing, the wall thickness of the pipe will generally transform slightly, either increase and also decrease. After many situations of sinking, the inner surface in the pipe is rough in addition to cracks will occur when it can be serious. The sinking method works for drawing small diameter aluminum tubes, special-shaped light weight aluminum tubes, as well while reducing and shaping little diameter aluminum tubes.

Much time core drawing

The aluminum tube billet is set freely on the surface polished core rod, plus the core rod and the particular aluminum tube billet are pulled from the die hole together to accomplish diameter reduction and wall membrane reduction. This method known as long core rod pulling. The length of the mandrel will be slightly greater than along the aluminum tube immediately after drawing. After the initial drawing, the mandrel will likely to be removed by either your stripping or rolling approach.

Long core rod drawing is characterized by way of a large processing rate, about 63%, but due on the need to prepare numerous diameters of long core rod and raise the tube stripping process, usually this technique is rarely used throughout production, it is ideal for the production of thin-wall light weight aluminum tube.

Fixed core scalp drawing

The core fly fishing line with core head is definitely fixed during drawing, as well as pipe blank can decrease diameter or wall through die hole. The surface quality of the aluminum tube drawn together with fixed core head surpasses that of sinking painting aluminum tube.

This method is most popular in the production connected with aluminum tubes, but drawing thin-wall aluminum tubes will be difficult.

Advantages Of Light weight aluminum Pipe Drawing Technology

1. The drawing aluminum tube is accurate larger and smooth in exterior.

2. Drawing is best option for continuous high-speed output of long products with very small cross sections. The wall thickness from the drawn aluminum tube is often as thin as 0. 5m.

3. Drawing production tools in addition to equipment are simple, easy to complete maintenance. In a same equipment we can produce some specifications and varieties connected with aluminum tubes.

In the long run, we will devote ourselves to the introduction of new drawing technology and also new drawing theory for aluminum tubes, so about save energy, material, enhance product quality and output. If you want for you to cooperate with us, you should not hesitate. Our aluminum tubes won't disappoint you.
