Roller Tube Expander Mandrel

Roller Tube Expander Mandrels are cutting and forming tools used in secondary metalworking machinery, specifically in the field of metalworking machinery. These mandrels are designed to expand tubes or pipes by applying radial force to the inner surface of the tube or pipe. This process is commonly used in industries such as HVAC, automotive, and aerospace to create tight and secure connections between tubes or pipes.

The roller tube expander mandrel consists of a cylindrical body with multiple rollers attached to it. These rollers are strategically positioned around the circumference of the mandrel to evenly distribute the radial force during the expansion process. The mandrel is inserted into the tube or pipe, and as it is rotated, the rollers exert pressure on the inner surface, causing the tube or pipe to expand.

The roller tube expander mandrel is typically made from high-quality steel or other durable materials to withstand the forces involved in the expansion process. It is important to choose the right size and type of mandrel based on the specific application and the dimensions of the tubes or pipes being expanded.

Overall, roller tube expander mandrels are essential tools in the metalworking industry for achieving precise and reliable tube or pipe expansions.
