Three-Line Cold Drawing Machine
Three-Line Cold Drawing Machine
The three-line cold drawing machine is a specialized piece of equipment used for cold drawing processing of pipes.
By applying a strong pulling force, the machine stretches the pipes to predetermined specifications, altering their diameter and length to achieve the required dimensional accuracy. It enhances the surface quality of the pipes, improving their smoothness.
The cold drawing process modifies the internal structure of the material, increasing its strength and hardness, thereby enhancing the mechanical properties of the pipes.
The three-line cold drawing machine has the capability for continuous production, allowing multiple pipes to be drawn without interruption, ensuring high production efficiency.
The structure of the three-line cold drawing machine consists of a DC motor main drive system, a hollow machine bed, a dual-chain hook-free drawing trolley, an automatic unloading rack, an automatic internal and external oil lubrication system, and a DC PLC speed control system.
