The most complete machine for the analysis of compression springs

shape and its encumbrance becomes bigger. All dimensions of the compressed spring also modify their values: • Length • Outside diameter of the coils • Pitch • Span between the coils The management of all these values is not easy. After a couple of years researching, measuring and testing, the engineers of MicroStudio came up with the most complete machine for analysing compression springs. Against the complexity and the volume of data that the operator can have from LED4D, there is the extreme simplicity of the using of the gauge: • Place the spring between the two plates • Press “start” and await the results The results are in the form of graphics or discrete values (numbers) that the operator can store in the usual figure (electronic sheet or CSV). MicroStudio produces the LED4D spring analyser in five models, from 250 N to 3.0 kN with a field of view of Ø38 x 48mm and Ø75 x 95mm. MicroStudio Srl – Italy Website : www.microstudiotec.it LED4D recognises, evaluates and measures all these parameters. • Call your recipe

MicroStudio defines the spring as: ‘the simplest but the most complex unknown piece of coiled wire.’ For more than 15 years the company has measured and tried to understand this little, complex piece of wire. As a result it has produced a tester that is able to analyse what happens to a compression spring that purely does its duty: to be compressed and to give back the received force. The gauge LED4D consists of a revolving set of plates, where the spring is placed. The spring is pressed and the set of plates turns around the axis plates/spring and, step-by-step, a camera measuring system collects and stores the images of the compressed spring, while a set of load cells discovers all the forces that come into play during this operation. All this is patent pending. Anybody who manufactures or uses springs knows that a compressed spring returns almost six types of forces:

•

Axial force Fz

•

Lateral force in “X” direction Fx Lateral force in “Y” direction Fy

•

• Overturning torque in “X” direction Mtx • Overturning torque in “Y” direction Mty • Axial torque Mo Furthermore, the same spring loses its
