How to reduce the vibration when the compression spring machine is working?

In the new period of social and economic development, not only new and upgraded regulations are put forward for various manufacturing industries, but also the pursuit of perfect green, environmental protection and high efficiency. Both the spring manufacturing industry and the compression spring machine manufacturing industry are facing challenges. Through market structure optimization and resource allocation, promote the survival of the fittest and achieve this healthy new social and economic development model. The spring and compression spring machine manufacturing industry must carry out strict quality control to produce high-quality products and prevent serious waste of resources.

At present, with the use and popularization of computer compression spring machines, the relative use of excellent spring mechanical equipment and excellent production technology has created a lot of profits for the company. During the entire application process of the compression spring machine, due to the operation and forming, production, processing and other reasons of the equipment, damping vibration will inevitably occur. After a long time, the damped vibration of the equipment will have a necessary impact on the equipment itself, and it will be more serious. Common failures caused by equipment.

Compression spring machines operate due to vibration, which can affect the characteristics of the equipment. How does one reasonably reduce damped vibration when this happens?

① Select anti-vibration measures. For example, the AC servo motor and the compression spring machine casing adopt a flexible connection method to protect the motor itself from vibration; the hydraulic press part of the equipment is separated from the equipment itself; hydraulic press buffer equipment is used to reduce the impact of component disassembly and replacement; vulcanized rubber or wood is used to protect the compression spring The machine and the roadbed, and the connection between the machine base and the road surface is separated by a vibration isolation groove, so as to prevent the surrounding vibration source from being transmitted to the equipment and the foundation according to the road surface.

② Avoid co-shock. Resonance means that the frequency of the excitation force of the equipment is close to or coincides with the resonance frequency of the system software, which leads to common failure conditions of the equipment. In order to prevent the resonance principle, such as changing the speed ratio of the AC servo motor/changing the speed ratio of the spindle bearing to bypass the resonance zone; improve the surface accuracy, and then reduce the surface roughness of the fusion surface to weaken the natural frequency: clear the gap and increase the bending of the touch Stiffness to increase the bending stiffness and resonance frequency of the equipment system software.

③Reduce/eliminate the exciting force of the vibration source. For parts with a speed ratio of about 600r/min, it needs to be balanced, especially for high-speed parts in the compression spring machine, such as transmission gears and rolling bearings, etc., it is necessary to improve the production and assembly line of the transmission gear, especially to improve the transmission gear. The accuracy of the root inspection of the unit, the reduction of vibration caused by frequent impacts, and the reduction of noise; the accuracy of the production and assembly lines of roller bearings needs to be improved to reduce damage caused by roller bearings. Disadvantages caused by vibration.

During the whole process of the compression spring machine, in order to prevent the occurrence of vibration and unnecessary damage to the equipment, three-stage vibration reduction measures can be taken to avoid resonance and reduce/clear the vibration source of the exciting force. Reduce vibration.
