Inertial force of high speed punching machine

The inertial force of high-speed punching machine operation, because the inertial force is too large, when the pneumatic balance cylinder is used, its size is too large, the speed of the slider is too high, and the pneumatic sealing ring cannot bear it. The upper and lower chambers of the pneumatic balance cylinder need frequent intake and exhaust, and there is no suitable pneumatic The valve can meet the excessively fast reversing frequency, therefore, it is not suitable to use the inertial force balance method in the form of a pneumatic balance cylinder on a high-speed punching machine.

The inertial force of the high-speed punching machine is the vibration generated by the punching machine through the vertical force acting on the crankshaft bearing end, the horizontal force and the force acting on the slide rail surface. Usually, the amplitude of the inertial force exceeds 20 times the weight of the slider, so the vertical inertial force is larger than the total weight of the punch machine. Such a huge inertial force can have a very serious impact on the normal stamping production of the punching machine, and the corresponding inertial force must be adopted. balancing act.

In order to reduce the inertial force and improve the balance effect of the inertial force, the mass of the rotary part and the reciprocating motion should be reduced as much as possible. Since the high-speed reciprocating motion of the slider is the main source of the inertial force, the quality of the slider should be reduced while ensuring the strength. The design should be as small as possible (such as drilling in the middle, using high-strength low-density alloys such as light alloy cast aluminum sliders, etc.); using double-crank double-point or four-point transmission; using advanced, highly adjustable, and easy maintenance. Dynamic balancing device.

When the high-speed punch press is running, the inertial force generated by the crank-link slider mechanism is much larger than that of the ordinary punch press. This inertial force causes vibration and noise pollution to the high-speed punch press and reduces its stamping accuracy. Balancing the inertial forces is extremely important.
