COMPRESSION SPRING PRODUCTION: HOW OUR LINE IS COMPOSED FOR SMALL DIMENSIONS
Here we are in the heart of the production area of our factory. Here is located the integrated line dedicated to the production of small compression springs and the related quality control.
Let’s see together which units it is composed of and what are the characteristics that guarantee the product high precision and reliability.
Winding: Simplex Rapid FX10
Simplex Rapid FX10 is a high-speed automatic wrapping machine, equipped with a latest generation Multi-axis Numerical Control; congenial for a specific production of compression springs, those with right-hand helix with even very complex variations in shape and pitch.
Performance and reliability
The performance and reliability of the machine are guaranteed by the maximum simplification and the reduction of the number of mechanical parts, which therefore lead to less wear and inertia. The high-performance programming software, perfectly integrated with the hardware, allows direct control of all tools.
Among the salient features of the machine we find:
- Motion Control Technology;
- High resolution digital transducers;
- Production control via video camera and backlight (SPC);
- Programming in microns;
- Extremely advanced and innovative software (SPG / SGP);
- Industrial PC with color touch screen;
- Integrated UPS unit.
Shot peening: Norblast TAP
The Norblast TAP automatic shot peening machine is equipped with an adjustable pressure or depression firing system, ideal for mass treatment of small springs. The abrasive selection and recovery operations take place automatically through a suitably sized cycloning system: conveys the crushed grit and waste dust to the filter
The plant is equipped with a PLC for the management of shot peening recipes and scheduled maintenance activities.
Dimensional and surface checks: Keyence VHX-7000 microscope
The Keyence VHX-700 is used to perform dimensional and surface checks. It is a 4K optical microscope, extremely easy to use even for inexperienced users: it allows the acquisition of images similar to those of a scanning electron microscope.
Vision and measurement
The microscope, equipped with a depth of field 20 times greater than traditional optical microscopes, is able to perform 2D and 3D measurements: suitable for both dimensional measurements and for evaluating roughness, contamination and other parameters with a single and effective instrument.
Lifespan test: Microstudio PMF-300
For fatigue tests, our laboratory is equipped with two Microstudio PMF-300 useful for tests on compression and traction springs of small dimensions.
These machines combine the characteristics of a high speed press with a brushless motor, allowing to perform simultaneous life tests on 12 springs, with continuous verification of the integrity of each single piece by electrical contact.
