High-speed precision automatic punching operation inertia force cancellation method
　　Speed presses crank rod inertia force by the slider mechanism generated during operation is much greater than the ordinary type punch inertial force, which makes high-speed presses to produce inertial force vibration noise pollution, and reduce its precision stamping, therefore, high-speed punch inertial force balance is extremely important.
　　After careful study, found that high-speed presses pu zhi de inertia force is the vertical force acting on the end of the crankshaft bearing, the horizontal force and the force acting on the guide surface of the slider leaving the press vibration. Typically, more than 20 times the amplitude of the inertial force slider weight, and thus the total weight of the vertical inertial force than punching machine, so huge inertia force of normal stamping presses can produce very serious impact on the inertial forces must take appropriate balancing measures.
　　To reduce the effect of the inertial force of the inertial force and improve the balance of the rotary parts should be minimized and the quality of the reciprocating movement, due to the high-speed reciprocating movement of the slider is the main source of inertial force, therefore, in ensuring the strength, the mass of the slider designed as small as possible (such as in the middle drilling, low-density high-strength aluminum alloys such as light alloy sliders, etc.); double points or double crank four-point transmission mode; using advanced, highly adjustable, easy maintenance homeostasis devices.
　　High-speed precision automatic punching to inertia force is too large, balanced pneumatic cylinders when its size is too large, the slider speed is too high it can not afford pneumatic seals, pneumatic cylinders and inferior vena balance the need for frequent intake and exhaust, no suitable pneumatic valve can satisfy this fast commutation frequency, so, should not be used in high-speed punching balanced pneumatic cylinders in a balanced manner in the form of an inertial force.
　　Configure the crankshaft eccentric structure in double crank drive two-point or four-point approach speed punch, you can get a good balance effect, therefore, it is the most widely used high-speed punch inertial forces in a balanced manner.
　　High-speed punching motion trend inertial force balance mechanism must slider contrary trends and movements, so as to play a good balance effect, try using symmetric bodies (such as multi-point <double points, four points> body). Such movement of the slider in a direction perpendicular to the inertia force can be offset from each other within the system, does not cause twisting of the swing speed presses.
　　For a given inertial force balance mechanism, various factors must be balanced by the effect of the inertial force (e.g., the size of each member, the centroid position of the fulcrum, etc.) to optimize the design, it is possible to obtain a good balancing effect of the inertial force.
　　Essence of high-speed precision automatic punching inertial force balance mechanism is to reduce the oscillation range of inertial force to punch a certain range, but not completely balanced, stable and unchanging average of a force of its own weight and the role of its common superimposed vibration damping base.
