UII FORM is the first intuitive software dedicated to end-forming machines, offering easy guidance and obviating the need to know any programming language. And their new MHM Industry 4.0 software enables internal and external cloud based communication between multiple machines and services like Siemens Mindsphere, which offers A.I.-based analysis of a machine’s condition.
Crippa’s Chief Technical Officer Domenico Fulco reported that MHM allows the customer to monitor production as an entity, as well as to zoom in on individual machines to view their overall equipment effectiveness (OEE) parameters, with up to 16 sensors applied to the machine components to record vibrations and operating tem- peratures. This data can be augmented by technical documentation, maintenance records, and information about energy consumption, all
The Crippa 980LE tube bending machine. Crippa’s software imports and exports geometric data for the tube, automatically creates the tooling, and simulates the bending and end forming cycle in 3D to verify cycle times and possible collisions
of which can be summarized graphically. “This information enables timely intervention regarding the anomalies detected and quick understanding of the nature of possible faults,” concluded Fulco.
Chiara Vaccari, corporate communication coordinator for the BLM GROUP (Cantu, Italy, U.S. HQ Novi, Michigan, https://www.blm- group.com) said the company’s BLMelements software suite enables the “360-degree management of tubular elements processing, from drawing and design through production planning, manufacturing, monitoring, and analytics.” One impressive feature, for example, is the software’s coordination of tube laser cutting and bending.
As Vaccari explained, “experience has shown that due to spring- back and material elongation, tube bending modifies the geometrical characteristics of the part and therefore laser cut geometries, previously carried out, will become out of position. With the traditional systems, this would mean other cutting and bending attempts each time, modify- ing the position of cutting geometries, until an acceptable result is obtained.” Such a sequence can become extremely expensive, she added, especially when different suppliers perform each function.
To solve this problem, BLM GROUP developed “All-In-One technol- ogy that makes Lasertube and tube bender software communicate
with each other,” reported Vaccari. “The tube bending machine estimates material elongation and the tube springback data from its database and communicates it to the Lasertube, which corrects the position of cut geometries on the tube, to provide the tube bender with a straight laser cut tube that will be correct after bending. Data is exchanged through a network and therefore they can be even exchanged from a long distance, so that Lasertube can cut tubes in one factory and the tube bender works in another site.”
Versatility/Versatilità
UCIMU member OMERA Srl (Chiuppano, Italy, www.omera.com) offers a range of hydraulic, mechanical and servo presses, as well as trimming and beading machines. Several of these disciplines are often combined, plus robots and various feeders, to deliver flexible turnkey solutions. In one such case, an important player in the HVAC market
OMERA Srl combines presses, trimming and beading machines, plus automation, to deliver turnkey solutions with the flexibility to handle small, customized batches of various galvanized steel ventilation parts
needed to produce small, customized batches of various galvanized- steel ventilation parts, such as elbow fittings, reductions, and “T” fittings. Yet they also wanted complete automation and high productivity.
To solve this problem, OMERA created a line that starts with a sheet-metal coil, which is then unwound, straightened, and cut into the particular square blanks needed for each product. The line includes both a C-frame eccentric press and a 400-ton hydraulic press, plus a number of other features that contribute to its versatility, such as a six-axis articulated robot, a quick-die-change system, and a three-tank lubrication system (one dedicated to the customer’s lubricating oil, a second with a mixer suitable for emulsifiable products, and a third dedicated entirely to the nozzle cleaning cycle, to be carried out whenever a customer changes production and type of oil).
The entire line can be controlled from the HMI of the hydrau- lic press, and all the machines are connected to each other and
