DB60 Tube Mill Line 242kW Pipe Making Machine PLC Control System

High-Efficiency DB60 Pipe Making Machine with PLC Control System Functionality

Product Description:

A tube mill is a vital piece of industrial equipment used in the production and manufacturing of tubular products, such as pipes and tubes. It is an essential component in the tube manufacturing process, which involves transforming a flat strip or coil of metal into a cylindrical shape and joining the edges through welding to create a seamless or welded tube.

The process of tube manufacturing begins with a flat strip or coil of metal being fed into the tube mill. The machinery in the tube mill then works to shape the metal into a cylindrical form. The edges are then welded together to create a continuous tube. This process produces either seamless tubes, where the edges are joined through pressure and heat, or welded tubes, where the edges are joined through welding.

Tube mills are essential in the tube manufacturing process as they provide the machinery needed for shaping, welding, and sizing the tubes. These machines are designed to produce high-quality tubes efficiently and accurately, resulting in a more cost-effective and reliable production process for tubular products.

Overall, tube mills play a crucial role in the production and manufacturing of tubes, providing the necessary equipment and technology for creating seamless and welded tubes that are used in various industries, including construction, automotive, and manufacturing.

Features:

The initial step in the tube manufacturing process is the uncoiler. This machine is responsible for unwinding and feeding a coil of raw material, usually steel, into the tube mill. The material is typically in the form of a flat strip or coil.

Some tube mills utilize a strip accumulator to ensure a continuous supply of material to the forming section. This helps maintain a consistent production flow, even when there are interruptions in the feeding process.

The forming section of the tube mill includes a series of rollers and tooling that gradually shape the flat strip into the desired tubular profile. This can be achieved through various processes such as roll forming or continuous bending. The formed edges of the strip are brought together to create a tubular shape.

In the welding section, the edges of the tubular shape are joined together through a welding process. Different techniques, such as high-frequency induction welding, TIG welding, or MIG welding, may be used depending on factors like material type and thickness.

After welding, the newly formed tube passes through a cooling section to solidify the weld and reduce the temperature of the tube.

The sizing section utilizes additional rollers or dies to achieve the final dimensions and roundness of the tube. This stage ensures that the tube meets the required specifications and tolerances.

Once sized, the tube is cut to the desired length using a cutoff saw or another cutting mechanism. Additional finishing processes, such as end facing and chamfering, may be performed to meet specific customer requirements.

Quality control is a crucial aspect of the tube manufacturing process. Various methods, such as ultrasonic testing or eddy current testing, may be used to ensure the integrity and quality of the tubes.
