Does the production noise of a precision high-speed press affect the stamping accuracy?

        Part of the use of high-speed press stamping production of enterprises on the production accuracy requirements are relatively high, especially after a long time with the noise of the machine and equipment has become larger, and thus some worry about the precision of the stamping. So, what is the noise of high-speed press, how does it happen? Will the noise have an impact on the stamping accuracy?

      High-speed press noise has no-load noise and load noise two types of occurrence. No-load noise is the noise when the high-speed punch press is running without information, which includes motor noise, impact noise occurring in the gap of the running parts, clutch and gear knocking noise, etc. The most important noise in this case is the noise from the clutch and gear. The most important noise source is the clutch and gear knock noise.

     Load noise is a high-speed press stamping product noise, the same high-speed press using different stamping process, the noise is not the same. The parts of the press where the noise comes from can be divided into the following kinds:
    High-speed punch press running parts gap noise, high-speed punch press crank connecting rod slider structure has three pairs of friction vice: connecting rod small head and slider ball seat; crankshaft journal and crankshaft tile; crank neck and connecting rod big head shaft tile. Due to production and debugging errors and practical needs, these parts of necessity between the existence of the gap. Relative movement between the components, from the free movement to the transition to touch the movement, inevitably bring bumping, the larger the gap, the stronger the noise. In addition, when the gap is fixed, the greater the number of slider strokes, the greater the noise.

     High-speed punch press motor noise, as a power source, motor operation noise including motor winding electromagnetic noise, aerodynamic noise and mechanical noise. The degree of motor noise is mainly due to the power and speed of the motor. Electromagnetic noise of the motor is generally formed by the alternating electromagnetic field mutual effect to stimulate the vibration of the rotor and stator, which is usually high-frequency noise.

      Clutch noise, when the clutch is closed, the general high-speed punch press will occur murmur. This is the slider, connecting rod in the reciprocating operation of the inertia force and the crankshaft of the centrifugal force of the rotating mass of the formation of the impact generated by the intermittent sound. Generate clutch noise of the primary factors are: clutch closed by the impulse of the magnitude of the state in the quality of a certain amount of impact depends on the speed of the punch press speed; but also with the touch of their own stiffness and damping characteristics of the material.
   These mechanical noise in the tonnage is enough for high-speed press, stamping accuracy has almost no effect. Therefore, we hereby call on the majority of customers in the selection of high-speed punch press, be sure to select their own noise, stable performance of a good punch press brand.
