Up and down gravity casting machine

The simplified transmission structure reduces vulnerable parts. Compared to the complex "hydraulic pump-cylinder-oil pipe" transmission of traditional hydraulic presses, the C-type Servo Press uses a direct "servo motor-ball screw" transmission, reducing common failure points such as hydraulic oil leakage and seal wear. Simultaneously, the C-type frame is made of integral casting (or welded steel plates with aging treatment), resulting in high rigidity (frame deformation ≤0.1mm/100kN), which can withstand the vibration and stress generated by long-term stamping, avoiding accuracy drift caused by frame deformation. Statistics show that the mean time between failures (MTBF) of the C-type Servo Press can reach over 8000 hours, which is 2-3 times that of traditional hydraulic presses, reducing equipment downtime for maintenance. The servo system boasts rapid response and excellent dynamic performance. The servo motor's response time is ≤0.1s, allowing for rapid adjustment of slider speed and pressure. For example, in multi-variety, small-batch production, switching products only requires modifying pressure, displacement, and speed parameters in the control system (without changing mechanical molds or adjusting hydraulic valves). Parameter switching response time is ≤10s, avoiding the cumbersome and time-consuming parameter adjustments of traditional presses. Simultaneously, during sudden load fluctuations (such as uneven hardness of stamped materials), the servo system can compensate for torque in real time, ensuring smooth slider operation and preventing equipment vibration or component damage due to load impact. Sensitive overload protection and high safety. Built-in multiple overload protection mechanisms: ① Pressure overload protection: When the actual pressure exceeds the set value by 10%, the servo motor immediately stops outputting and reverses, preventing damage to the frame and mold; ② Displacement over-limit protection: When the slider stroke exceeds the set upper/lower limit, the system automatically cuts off power and locks to prevent mechanical collisions; ③ Motor overload protection: When the servo motor current exceeds 120% of the rated value, thermal protection is triggered to prevent motor burnout. These protective functions have a response time of ≤0.05s, which is much faster than the mechanical protection of traditional presses (such as safety bolts), significantly improving the safety of equipment operation and reducing the risk of workplace injuries and equipment maintenance costs.
