Pipe fittings are processed into semi-finished and finished products through a pipe expanding and shrinking machine combined with a pre-forming mold.
Tube expanding and reducing machines are used to alter the diameter of the tube ends, either expanding or reducing them to specific sizes.
The principle of operation involves placing the tube onto a fixture with clamping dies. The system utilizes an electric control system to operate a pneumatic system that drives a mandrel to perform linear reciprocating motion. During this motion, the mandrel rotates while it contacts the tube end, initiating deformation. The deformation zone at the tube’s end undergoes either tangential stretching or compression, resulting in the required expansion or reduction of the tube's diameter.
This process is versatile, allowing for customized tube sizes based on specific product requirements. The tube expansion or reduction process is commonly used for applications where precise control over tube dimensions is crucial.
