A tube drawing machine is an industrial equipment used in the manufacturing process to reduce the diameter and wall thickness of metal tubes while maintaining or improving their overall length. This process is known as "tube drawing" or "cold drawing" since it is typically performed at room temperature.
The tube drawing process involves pulling a hollow metal tube through one or more dies with smaller diameters, resulting in a final product with precise dimensions, improved mechanical properties, and a smooth surface finish. The process can be performed using various methods, such as:
Rod Drawing: A mandrel is inserted into the tube, and the tube is drawn over the mandrel through a die. This method helps to maintain the inner diameter while reducing the outer diameter and wall thickness.
Floating Plug Drawing: A floating plug is placed inside the tube, and the tube is drawn through a die. The plug moves freely inside the tube during the drawing process, ensuring uniform wall thickness reduction.
Tethered Plug Drawing: Similar to floating plug drawing, but the plug is connected to a rod or wire that controls its movement within the tube.
Sinking Drawing: The tube is drawn through a die without any mandrel or plug, resulting in a reduction of both the inner and outer diameters. This method is typically used for smaller reductions or when precise control over the inner diameter is not critical.
Tube drawing machines are widely used in various industries, including automotive, aerospace, construction, and oil and gas, where high-quality metal tubes with specific dimensions and properties are required. These machines can work with a range of materials, such as steel, stainless steel, aluminum, copper, brass, and other alloys.
