Switchgear is enclosed in a NEMA style cabinet complete with an external, Lock-Out/Tag-0ut fused disconnect. Bend cycle is controlled by a reversing contactors, motor overload protection modules and a control transformer, all which meet NEC, JIC and UL specifications. The bending arm is powered by an electric self braking, brushless SEW-Eurodrive right angle motor reduction unit mounted under the table. STANDARD EQUIPMENT: These Pedrick machines have a work surface and rotating top plate in heavy normalized steel plate mounted on a solid cast or alloy steel base frame. However, when the radius of the bend is smaller and/or the wall is thinner, it becomes necessary to use a ball mandrel and wiper die to maintain the proper shape.

For tubing 3/8 in diameter and smaller a plug mandrel produces the best results. A variety of structural, roll formed and extruded sections can also be formed using the rotary compression process saving time and money! Mandrel pipe bending begins with the tube being pulled over a mandrel held in a fixed position. The wiper arm locks into the rotating top plate. THE CONCEPT: The Rotary Compression Bending Principle uses a stationary forming die and a powerful wiper arm that rotates around the die which pulls the work piece around the die to create the bend. Inspection can be accomplished with a non-contact tube measuring machine or with functional gages.Bends produced on a 3D bend radius meet American Petroleum Institute (API) specifications for ovality (flattening) and wall thinning. We can reverse engineer samples with our sophisticated measuring equipment or use customer-supplied models and CAD data to create part programs. Through the use of robotic and CNC tube bending equipment, we can produce very complex tubular components. We also produce bent and trimmed tubes for exhaust system manufacturers who assemble and weld the parts into finished exhaust headers and collectors. These parts are most often produced for clients that are working on prototypes where final dimensions and features have not been determined or in very small-volume niche industries where tubes are being hand-fit for each application. Simple bent parts are either supplied to the customer “as bent” or with specific trimmed leg lengths. We use this method to produce oil lines, fuel lines, hydraulic lines, oxygen lines, and many other fluid and gas tubes. By eliminating the use of a mandrel, parts can be easily processed with robotics and automated equipment and may not require any clean-up of bending lubricants. This is accomplished by using specialized tooling and selecting the proper material and bend radius. Many smaller diameter tubes can be bent successfully without a mandrel while maintaining acceptable levels of collapse and distortion in the bend area. This method is commonly used in intake and exhaust pipes, aircraft components, and hand rails.

In addition, post-bending cleaning processes are usually required to remove drawing lubricant used during bending. This method is often more expensive than other bending practices due to the complexity of the tooling and set-up processes and because it is more difficult to automate loading and unloading. It is also used in decorative applications with demanding visual requirements. This is most often used in tight radius and thin tube wall applications or where a constant flow area is critical to the performance of the product. Mandrel tube bending is used to produce tubes with minimal collapse in the bend area. We primarily use the Rotary Draw Bending method, where the tube is drawn around a bend die. We have the equipment and tooling to bend tubing from. Home - about - continuous improvement - contact us / request information Tube
