The automation systemensures quality and leak tightness in a fast 90 seconds cycle
In the air conditioning and heating technology as well as in the plant construction, the spiral tube heat exchangers are on duty. The core for the production is only one long tube part. Special requirements of the tube processing is the precise and parallel bending of the two ends of the spiral or a frontal sealing surface, additional to the thread seal. The specialists of transfluid designed an intelligent automation system for heater spirals with lateral connection points for tubes with diameter ½ “ till 1 ¼”. The realization of the efficient new developments started with the individually adapted t motion- technology.
In the fully automatic process, after the rolling process the robot take the spirals to put them into a special right/left mandrel bending machine. “This very special bending machine is able to bend the two ends of the spiral exactly parallel. In fact this is possible when the outgoing units are on the face side as well as they are on the side. To get the necessary precision and process reliability, the robot put the spiral at first in a measurement unit. Here the diameter of the spiral and the lengths of the outgoing units are detected automatic and exact”, according to Benedikt Hümmler, the general manager construction/production of transfluid.
Solution for special sealing surface
The further processing of the ends happens in this machinery as well.A particular customer request for the manufacturing process was, next to the thread - that is used for sealing - achieve also an front-face sealing surface.After the installation this area will be sealed with an additional element. The solution of the German engineers:A robot with double gripper takes the spirals from the bending machine to give them to the processing machine. The measurements which are determined before bending are used here again to ensure that the length and the angle of the both ends to the spiral coil are exactly identical.
Afterwards the tube ends are cut in an orbital chip less cutting process. Then there is a calibration process of the area where later the thread and the frontal sealing surface are located. In the next step the transfluid- manufacturing cell cuts the threads and machines the frontal sealing surface.
“The handling and the re very heavy”, said Gerd Nöker, the general manager of the sales department/marketing of transfluid.All those in transfluid who have brought their knowledge and skills to the development of this particular machinery, are happy that it meets the requirements to 100 percent. The t-motion automation system can be controlled from one person and convinced with the sporty cycle time of 90 seconds for the whole process.
