Ways to reduce the vibration of the aluminum plate engraving machine
The vibration of the aluminum plate engraving machine is one of the main reasons for the broken knife. What are the methods to prevent the vibration of the aluminum plate engraving machine? Let us look at the way to reduce the vibration of the aluminum plate engraving machine:
1. Vibration isolation: In order to reduce the influence of the nuisance, an obstacle is set in the vibration notification road, so that the vibration source can not be transmitted to the tool or the workpiece. According to the amplitude-frequency characteristics of the forced vibration, the amplitude of the vibration system is known. Regardless of the frequency of the disturbance force, when the frequency of the disturbance is greater than the natural frequency of the system, although the magnitude of the disturbance force is stable, the amplitude is reduced, and the larger the ratio, the smaller the amplitude.
2. Vibration reduction: The engraving machine is equipped with an additional device in the process system. This additional device can absorb a disturbance. It is similar to the interference force of the system, with the same bias and similar frequency, so as to offset the interference of the original system.
3. Reduce or eliminate the imbalance of the reverse rotation machine in the process system: in the process system, the high-speed reverse rotation of the workpiece, machine tool spindle components, electromechanical and grinding wheel imbalance will produce periodic interference. In order to reduce such interference For the same normal reverse rotation parts should be balanced, the high-speed reversal expansion parts should be balanced. The disturbing vibration source like the grinding wheel, in addition to static balance, because the grinding wheel wear uneven or adsorbed in the grinding process The uneven distribution of the grinding fluid on the surface of the grinding wheel will still lead to a new imbalance. In the case of fine grinding, the active or semi-active equalizer is proposed. In the mechanical layout design, even if the quality of the high-speed reversing machine is reduced, Spread unevenly to prevent interference caused by imbalance.
4. Improve the accuracy of the whole system transmission parts: the gears, rolling bearings, belts, etc. in the transmission parts of the aluminum plate engraving machine, they will wear out during high-speed transmission. The method of processing is to improve the manufacturing precision and device precision and choice of the whole machine. Worn material.
5. The dynamic characteristics of the further process system: that is, increasing the rigidity of the process system, increasing the damping can reduce the vibration of the system. In addition, the natural frequency of the mechanical layout should be properly arranged to avoid the resonance zone.
