Aluminium bronze alloys

The benefits of CNC tube bending AddisonMckee manufactures a large range of all-electric, hydraulic and combination tube benders from 4mm to 273mm diameter. The company offers four lines of CNC tube bending machines to meet the demands of manufacturers across industries. CNC tube bender models provide accuracy, repeatability, quick tool change and ease of operation. CNC tube benders add a new level of speed and precision to rotary draw bending. The value of CNC bending increases in direct proportion with the complexity of the tubular part. The more variety there is between radii of the bends, the more important it is to have CNC equipment. CNC equipment manipulates the tube to precisely position the various bends relative to each other. CNC tube bending is usually employed when a part contains more than two bends. The new PowerBend range of CNC tube bending machines caters to manufacturers requiring standard three axis solutions, while AddisonMckee’s flagship DataBend series includes all electric, hydraulic and combination tube bending machines from 4 to 273mm diameter. AddisonMckee has also designed a range of specialised, electrically powered, hydraulically operated elbow tube benders. Developed to answer the demands of the plumbing industry, the ElbowBend series is capable of delivering six 90° or 45° copper elbow joints every 7.2 seconds. The company’s FormMaster-70 ram extrusion machine, or FM 70 RE, has been designed to produce small bent components at high speeds with minimal scrap. In March AddisonMckee announced an agreement to merge with Eagle Precision Technologies, a leader in muffler manufacturing and bending solutions. As part of the agreement AddisonMckee acquired defined assets of Eagle Precision Technologies, including designs, drawings, software and trademarks, while excluding its liabilities, facilities, and certain equipment. AddisonMckee’s Eagle TM brand of bending machines are designed to meet demanding requirements, and incorporate the latest technology for automatic tube bending. The range of machines can handle tubes from small diameters up to 150mm (6").

Ampco Metal provides high-tech alloys for demanding applications, including a comprehensive range of high-performance aluminium bronze alloys for pressings, tube bending, deep drawing, rolling and roll forming applications. The company guarantees a wide range of materials satisfying the highest require- ments, such as the patented alloy Ampco ® 25 for tube forming rolls, and Ampco18, 21 and M4 in the tube bending sector.

In addition to alloys, Ampco Metal has extensive machining facilities and can assist customers at times of peak demand by offering a full or part machining service to smooth their production programmes and avoid bottlenecks. Ampco Metal SA – Switzerland Fax: + 41 26 439 93 01

Cold bending machines for boiler and power station manufacturing

Schwarze-Robitec GmbH, Germany, a manufacturer of tube cold bendingmachines, has recently delivered several machines to boiler and power station manufacturers. These machines are developed to produce tight radii, even less than R=D, in tube serpentines and single bends, with PC CNC control for highly accurate movements of all axes. The machines can be equipped with magazine and automatic loader, as well as automatic cutting saw, automatic 1D/3D bending and bending facility for bend-in- bend compound systems. A flip-over table for synchronous rotation of flat serpentines in connection with the orientation device is also available. The latest PC CNC control offers many features for entering the values necessary for the production of high quality products in the shortest possible time. The simple control offers easy access to automatic and manual operating modes and system diagnostics.

The bending results are within the latest EN 12952-5 European standard for water- tube boilers and auxiliary installations approved in 2000. Due to the control feature of using eight different boosting pressure parameters in one program, it is possible to satisfy the requirements of different bending angles with different materials in one product or serpentine. Together with the production of tight bending radii down to R=D, it enables the manufacture of boilers in smaller dimensions, but with higher capacity, which can be used in the most modern (fossil fuelled and nuclear) power stations. With the use of a mandrel, bending of thin-walled tubes to tight bending radii is possible, since the booster unit relieves the outer wall of the bends. Schwarze-Robitec GmbH – Germany
