Description
- Piston rod:Medium-frequency hardening of 45 steel, deepening the material 2-3 mm, making the surface hardness of the piston rod to 55,effective solution to seal ring injury，not easy to scratch it.For the workpiece after medium-frequency quenching, we use the lathe to soft throw it, and then use an cylindricall grinding machine to repair the deformation, to ensure the accuracy.
- This series of machine tools can be used for shafts and other similar calibration processes, as well as for press-fitting of shafts and sleeves, and stretching, forming and blanking of simple versions. This series of machine tools adopt foot pedal linkage operation , which is easy to operate. The hydraulic series adopts electro-hydraulic directinal valve or cartridge valve, which is compact in structure, safe and reliable , and sensitive in action. With features of fast speed, low energy consumption and low noise.
- Advantages of servo motor:Precision: closed-loop control of position, speed and torque is realized; The problem of stepping motor is overcome.speed: high speed performance, generally rated speed can reach 2000 ~ 3000 RPM; adaptability: strong overload resistance, can withstand three times the rated torque load, especially suitable for the occasion of instantaneous load fluctuation and fast starting;
- stable: low speed operation is stable, low speed operation will not produce similar to stepping motor stepping operation phenomenon. Suitable for high-speed response requirements of the occasion; timeliness: motor acceleration and deceleration of the dynamic corresponding time is short, generally within tens of milliseconds;comfort: heat and noise significantly reduced.
>
This series of hydraulic press is suitable for stretching, bending, flanging, cooling, blanking and other processes of metal materials.
