The Vernon Tube Tools Expanding Equipment Also known as the Model H System, our hydraulic tube expanding system includes the following important advantages: Increased Production Vernon's hydraulic tube rolling system creates a quality leak-proof joint in three to five seconds -- 1/4/ the time of competitive machines. Continuous mandrel rotation, coupled with automatic axial movement, eliminates time lost by other systems that reverse mandrel rotation for traction. Even under load, the hydraulic system maintains constant RPM, delivering equal pressure to the rolls for a tight fit between tube and tube sheet. Controlled Tube Joints Precision tube expansion is ensured thanks to Vernon's "preset" design. Control of advancing force, rate of feed and torque on the mandrel are automatic, minimizing tube end and tube sheet distortion while producing a leak-proof joint with precise control of advancing force. Ease of Operation Press the cycle switch and the mandrel automatically advances in the expander, expanding the tube end and retracting for the next cycle savng time and reducing operator fatigue. Longer Tool Life Automatic tool lubrication, single direction rotation and greater roll-to-mandrel contact combine to increase tool life and reduce consumable costs. Easy Maintenance Durable, heavy duty construction ensures long, reliable life. A large oil tank and external filter provide cooler running hydraulics and easy filter replacement. |
