Development history of CNC punch press

The first generation of mechanical CNC punch

The main motor output drives the flywheel and the clutch drive gears, the crankshaft connecting rod is operated to realize the linear motion of the slider of the machine is characterized in that the movement of the flywheel, (or eccentric gear) motion is changed in a linear motion design principle; Ring Stamping Stamping stroke is fixed, can not be adjusted, so the punching plant stamping speed. Second, because the stroke of the head is not adjusted, stamping is not easy to control, only by adjusting the mold to achieve the desired effect, adjust the degree of difficulty and trouble, but also the machine noise, need to replace the clutch plate shortcomings, solid phase out

Second – generation hydraulic CNC punch

Hydraulic press design principle is through a special hydraulic station, hydraulic cylinder driven against the head, by the electro-hydraulic servo valve control stamping parts, because of its controllable travel, so you can adjust the nozzle travel without going back to top dead center (professionals Called the pre-pressure point, which is shortening its stamping stroke) ideal speed to complete the desired effect of stamping, each done, to 600-800 times / min. Because of its ease of use, high efficiency, (is about 3 times the mechanical type) is a reasonable price, has been widely used, is the mainstream of the market stamping equipment.

Third – generation servo – NC punch

Driven by the servo motor directly against the head, the servo punch design principles. Because the fixed servo motor does not consume power, so this type of hydraulic phase pressure compared to some, but its higher prices, the market is not much users.
