Principle of Operation of Precision Punching Machines

     The principle of operation of a precision punch press is mainly based on motor drives and mechanical transmissions. The following is a detailed explanation:

    Motor-driven: the precision press works by motor-driven movable pulley, which in turn drives the synchronous belt-driven pulley to rotate.
    Mechanical transmission: The rotating pulley drives the crankshaft pulley, which in turn drives the counter-rotating crankshaft through the crankshaft gears, thus driving the stamping action. When the main crankshaft and crankshaft rotate in reverse at the same speed, the four sets of crank connecting rods drive up the synchronous movement.

    Stamping action: the shaft of the four links is movably connected by the lower part of the sliding device, and the reciprocating left and right sliding pins driven by the reciprocating motion of the four links at the lower part achieve the relative motion between the upper and lower moulds and the moulds, so as to exert pressure on the material and make it plastically deformed, and get the required shape and precision.
