Pipe bending: Cost-efficient bending of hose fittings

June 12, 2012 - PRLog -- Special solutions are required for special requirements – or just one efficient, customisable solution. For one-part hose fittings the german transfluid Maschinenbau GmbH has developed such a "twin" pipe bending solution and will equip its tube bending maschines systems with different modules depending on the application, varying mostly in the loading system. The challenges: Fittings are mostly mechanically processed, extremely short, relatively thick-walled and their sealing elements (sealing head or hose part) must not be damaged under any circumstances. "Cost-efficient processing options with our tube bending maschines are an aspect on which we place great emphasis. Large amounts of pieces are mostly manufactured for small sizes. And what counts here is the speed", says Gerd Nöker, the CEO of transfluid.

Pipe bending: Short cycles and bulk material hopper
The fittings bending machine for sizes up to 1 inch is fitted with a bulk material hopper with a capacity of 600 litres. The advantage: Fittings of any size can be loaded. A powerful drive is ensured by servo-electrical or hydraulic equipment. Bending can be therefore done in amazingly short cycles from 6 to 7 seconds including the entire handling. Special supporting elements ensure that the sealing cone and hose connections remain undamaged. Fittings starting with inner diameter of 8 mm are bent by the transfluid system always with an internal mandrel, so that bend ovalisation can be ruled out.

Tube bending maschine: Special handling of fittings with a diameter of up to 75 mm
Components with dimensions up to a diameter of 75 mm are transported by using a particularly robust loading system. As the weight of these fittings is so high, the loading system of the tube bending maschine prevents the components from uncontrolled falling down. The work pieces are therefore provided on a special pallet, taken from the handling system and supplied to the tube bending machine. These sizes are generally bent by the tube  bending machines with an internal mandrel. A maximum ovalisation of 3 percent is given. Also for large component, special supporting adapters ensure that each piece is discharged in the optimum way in the process. Flanges or other sealing elements will stay safe from damage. Even for fittings of this size, the entire processing time of the tube bending maschine  is maximum 25 seconds.
