Steel Automatic Tube Welding roll forming machine is designed to produce welded pipes of 32～127mm in diameter and 1.0～3.5mm in wall thickness as well as square and rectangular pipes and deformed pipes of the corresponding size. Adopting roll pass design, the production line can manufacture welded steel pipes with good quality machining and high precision assembling.
The decoiler of Steel Automatic Tube Welding roll forming machine is of the structure of double expansion and cantilever mandrels. It contains two main parts: main body and the fixed base. The main body is equipped with pneumatic system to satisfy the needs of expanding, contracting and braking of the mandrels.
Its main function is to store a certain amount of steel strip for supplying main machine before it doing head and end welding to make sure main machine’s continuous production without stopping
(1) Structure: squirrel cage type plate welding part with automatic feeding and delivery system.
