  The following are the methods to carry out the precision adjustment of high-speed blanking press:

First, the accuracy adjustment related to the slide and guide rail
    Parallelism adjustment
        Measurement of existing parallelism: Use a level meter or a professional parallelism measuring tool to measure the parallelism deviation between the slider and the guide rail at different positions of the slider (e.g. front end, back end, left and right sides, etc.). For example, place the level meter on the slider and observe the position of the bubble to determine the parallelism situation.

        Adjustment of guideway inserts: If the parallelism deviation is out of the permissible range, correct it by adjusting the guideway inserts. Tighten or loosen the adjusting screws of the inserts to make the gap between the guide rail and the slider change evenly, so as to adjust the parallelism. The adjustment process should be measured several times to ensure that the parallelism meets the requirements, generally required parallelism within 0.05mm/1000mm.

Second, mold installation accuracy adjustment

        Initial installation of the mold: install the mold on the slide and table of the press, use the mold pressure plate and other fixed mold, but do not completely tighten.
        The thickness of the piece or adjust the tightness of the thrust bearing to make adjustments.
    Connecting rod length adjustment

        Analysis of influencing factors: Changes in the length of connecting rod will affect the stroke of the slide and the accuracy of the stamping position. When it is found that the stamping depth is unstable or the stroke is inaccurate, it is necessary to consider adjusting the length of the connecting rod.
        Adjustment method: Change the length of the connecting rod by adjusting the adjusting nut on the connecting rod or adopting the adjustable connecting rod mechanism. When adjusting, pay attention to keep the length of the left and right connecting rods the same, in order to ensure the smooth movement of the slider. After adjustment, test punch should be carried out to check whether the size and positional accuracy of the stamped parts meet the requirements.

High-speed punching machine rotates the flywheel driven by the electric motor to store energy, and then releases the energy of the flywheel instantly through the control of the clutch and brake to drive the slider to carry out high-speed reciprocating motion to realize the punching action.
