Machining flat or three-dimensional coils with small tube diameters

dimensional graphic programming of the piece is made simple and intuitive, and a simulation of the execution avoids multiple attempts during the production stage. In order to supply the coil, the 4-Runner H1 is equipped with a new reel with clutch, which allows it to work in neutral with commands inserted directly by the work program. Orbital cutting, both internal (4RIPC) and external (4RC), on the 4-Runner H1 is also completely electrical. Two brushless motors control the rotation and movement of the cutting wheel, ensuring precision and process repeatability. 4-Runner H1 is an I4.0- compatible system. BLM SpA specialises in the production of CNC tube bending machines, end forming, wire bending equipment and related automation devices. BLM Group – Italy blm@blm.it www.blmgroup.com a primary circuit. The system that distributes the fluid inside each individual house is called the secondary circuit, and this is where the quality of the press fittings is a factor. Advantages of press fittings in creating secondary circuits for district heating systems include reduced installation times compared to traditional plumbing fitting systems. A ‘sleeve’ that tears and falls after pressing shows if a fitting was pressed or not. The presence of the LBP trickle O-ring in a toroidal shape – an exclusive Eurotubi patent – during the water pressure test, allows unpressed fittings to trickle conspicuously.

starting from the bending head, was to reduce the dimensions as much as possible, to allow the production of components that could not be manufactured previously. As part of the latest generation of completely electrical systems, the 4-Runner H1 bends by flexing right and left in process, and is multi-radius capable, with the possibility of variable radius. It can be easily integrated with a Smart bender to produce a complete system, which the BLM Group refers to as ‘bending with mandrel from coil’. All of the 4-Runner H1’s movement axes are electrical, including the blocking and support. Calibration of the equipment is easily performed thanks to the torque control, and saved with the part program. With no mechanical adjustments, maximum repeatability of parts during bending operations and tube forming is ensured, with measurement in real time. VGP3D programming software for tube benders by BLM Group can also be used in the 4-Runner H1. Three- District heating is a convenient system for climate control of entire neighbourhoods. From substations for each building to individual radiant units for all apartments, Eurotubi steel press fitting systems are suitable for creating distribution systems. Even if not able to use renewable sources directly, district heating is one of the least ‘wasteful’ climate control systems in terms of energy consumption and atmospheric emissions. For the most part making use of dynamic energy transformation processes necessary for other purposes, such as thermal energy coming from large industrial plants, a large amount of residual heat can be used to heat water or steam. The fluid obtained is distributed to houses in the area near the plant through
