KTI(Germany) - Spring isolators for vibration and shock control in forging hammers and power presses
Dynemech offers spring isolators of M/s KTI - Schwingungstechnik, Germany for Forging Hammers and Heavy Power Presses. M/s KTI Schwingungstechnik, Germany specializes in the design and manufacture of coil spring isolators and viscous dampers for large industrial equipment. KTI has over 15 years experience with heavy duty spring isolators solutions. The vibrations caused by forging hammers cause wide ranging disturbances to the surrounding areas. The installation of KTI Spring Isolators stops these vibrations being passed into the environment. KTI's modular system developed in 1998 can now combine elastic-plastic-viscous or Viscous Safety Damping. The new elastic-plastic-viscous safety damping ensures a high degree of isolation combined with a higher reduction of the movement of the machine. The Elastic-Plastic-Viscous is not influenced by oil, water or other aggressive fluids as the viscous system can be. Also the new damping system is stable over a wide range of temperatures. This "Next Generation" of KTI Modular Spring Isolators combined with either the Viscous or Elastic-Plastic-Viscous safety damping allow a compact construction and efficient layout, so enabling a very competitive pricing. All spring isolators are delivered complete and ready for use.

The numerous benefits associated with the use of spring vibration isolators are :

Dynemech is providing anti vibration solutions to the Indian Industry for the last 10 years. We are the only company to provide almost all types of vibration control solutions under one roof. Our product range consists of stud mounts for very small machines to wedge mounts for precision machine tools, along with air springs for very low natural frequency vibration damping to spring isolators for heavy presses, hammers, gen sets etc.

A spring isolator gives desired natural frequency to obtain phase difference in the frequencies for a rotating machine. Viscous Damping is an important feature of an isolation system. In most cases viscous damping is required to limit excessive movement which could occur as a machine operates at a speed near to, or coinciding with the resonant frequencies of the system. Generally this problem arises during slow run up and run down of rotating machines and during impact at each stroke in presses and hammers.

Advantages of Spring Isolators :

• Very high vibration and shock isolation
• Better Structural Safety
• Improved Health Protection of workers - reduced machine operator fatigue and provide more congenial working environment
• Installation of sensitive equipments and heavy machinery possible in the same workshop
• Shop Floor Flexibility Maintains
• Extended tool and machinery life.
• No foundation is required for small and medium weight machines and reduced depth of foundation for very heavy machines
• Simple to install and reliable.

Applications :

• Power Presses
• Forging Hammers
• Fans
• Blowers
• Generating Sets
• Centrifuges
• Test Beds
• Textile Machines
• Reducing Mills and Mixers
• Coal and Stone Crushers
• Refrigeration Units
• Pumps and Boilers etc.
• All types of heavy industrial machinery

The Springs are made in top grade wire & finished with protective coatings thus ensuring trouble free service life.

Selection Procedure

• Determine the all-up weight of the machine to be mounted including work loads
• Estimate the position of its combined center of gravity in both horizontal and vertical planes allowing for work loads & any mobile loads, i.e. Traversing work heads or tables etc.
• Decide where the mountings are to be positioned.
• Select mountings to give the required static deflection.
• Where especially very high levels of isolation is required, for instance where the disturbing frequency is less than 12 Hz, higher deflection springs may be necessary. We will advise.
