With the progress and development of science and technology, energy saving and environmental protection, punch processing effect of the author, increasing emphasis on light weight processing, press manufacturers punch technology in the development of the performance of the press also put forward more stringent requirements, here is the hydraulic punch appears A new generation of punch under the environment came into being. Hydraulic presses are considered third-generation punches. Servo presses use servo motors instead of conventional frequency-converting motors as the core power of the press. They are used in motors that do not require constant energy storage operations, and transmit to the adjustment and control It is an energy-saving, environment-friendly, lightweight, safe, high-efficiency, high-precision and widely used stamping processing equipment to meet the different needs of stamping processing production.
Hydraulic press as the earliest domestic manufacturers, the production of servo presses than the traditional punch has the following advantages:
Hydraulic punching machine in general the applicability of the operation, more convenient
The hydraulic press device is controlled by a full set of servo system which is formed by a reciprocating motion curve which is no longer a single motion but a single movement according to the ramming process, different materials, different widths, different thicknesses of the optimized group Free-flowing curve. Servo presses are equipped with several sets of NC processing curve database, which can store different processing curves and stamping parameters freely according to demand. Only use the required processing curve according to the characteristics of the stamping process, the stamping process is high speeding.
2, the hydraulic punch press molding accuracy than the average higher
The hydraulic press uses a linear scale to detect the position of the slider, and the sliding parts during the stamping process have good precision in motion control, especially near the dead center, to ensure that the accuracy of the + / slider is 0.01 mm; through the servo press Closed-loop feedback control to ensure that the punch under the high-precision die in the production process is stable and inhibit stamping products, burr, and fundamentally avoid the adverse stamping products.
3, the hydraulic punch press than the average production efficiency
(1) the general punch, increased production efficiency, can only increase the slider stroke frequency, but the slider stroke caused by the number of high-speed changes in the formation of adverse effects of products; servo presses can be allowed to travel under the circumstances shrink and reduce the forming Speed, speed up the processing range of the slider speed, reduce unnecessary waste, effectively improve the efficiency of stamping production.
(2) more servo punch and servo-independent manipulator, not only can easily be the best adjustment, save energy consumption, but also to avoid artificial participation in the production of a variety of adverse factors such as: slow, dangerous and erroneous operation Efficiency, increased production capacity and safety.
4, hydraulic presses to save energy
Using the servo motor punch, work entirely by the motor torque, punch through the organization required the impact of the drive, no clutch, the motor drive unit to control the motor start and stop the motor rotation only when there is punching, remove the universal motor and flywheel blank, To save energy consumption.
