Motor：50HP
Applicable material：brass, aluminium, steel and alloy tube and bar
Applicable size：Ø75-50mm / Ø50-35mm
Working range：15~30%

Applications and features：
1. Seesaw-type drawbench with the chain-driven carriage to pull out the rolled or extruded tubes for better precision.
2. Cold drawn materials provide precise size on diameter, wall thickness, and brighter surface at room temperature.
3. Cold drawn materials improve the hardness, reduce the duductility, and increase the yield and tensile strength of the material.
4. With assistance from the tube pushing machine and PLC, it effectively reduces the working time on mandrel insertion and collection for cold drawn tubes.
5. By carrying out multiple passes of cold drawing, it is capable to draw deductible round materials to various shapes for industrial use.
6. Pulling force, speed, and drawing length could be custom-made according to the practical process deriving from the material composition.

Relevant working processes：Extrusion, tube forming, cold rolling, pickling, coating, heat treatment, cutting, bending, straightening

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.
