The servo motor drive of the hydraulic press is to replace the ordinary motor of the transmission press with a servo motor, which is a servo hydraulic press. The movement curve of the slider of the servo hydraulic press can be set according to the stamping process, and the stroke is adjustable. This kind of press is mainly for high-precision forming of difficult-to-form materials and complex-shaped parts.
The development of servo hydraulic presses is heavily influenced by servo motors. At present, hydraulic presses driven by servo motors are mainly small-tonnage presses. In order to break through the limitation of servo motors, the hybrid drive mode is a development direction of presses at present. The composition of this hybrid drive press uses a differential wheel to realize the mixed input of ordinary motors and servo motors, and uses a two-degree-of-freedom rod system to realize a hybrid closed double-point press. Its characteristics are:
(1) High level of versatility, flexibility and intelligence
Due to its servo function, the slider motion curve is no longer just a sinusoidal curve, but an arbitrary curve that can be optimally designed according to process requirements.
(2) High precision
Due to the use of linear grating rulers to detect the position of the slider, the slider has a high motion control accuracy throughout the entire working process of the press, especially near the bottom dead center, which can ensure that the accuracy of the slider changes within ±0.01mm; thus ensuring that the press The accuracy of the closed height is stable during the production process, which can suppress the appearance of product burrs and prevent the production of defective products.
(3) High productivity
Because the servo hydraulic press retains the advantages of the crank press, especially the productivity is much higher than that of the hydraulic press, it embodies "the processing quality of the hydraulic press and the production efficiency of the mechanical press". Not only that, the crank press driven by the servo motor can also adjust the stroke of the slider according to the different workpieces. In one cycle, it does not need to complete a 360-degree rotation, but only swings at a certain angle to complete the stamping work, which further shortens the cycle. time. Minimize unnecessary trips and greatly improve productivity.
