Application Scope of Precision CNC Hydraulic Press Machine：(Digital Press Machine, Motor Pressing, Interference Detection Equipment, Hydraulic Press, Servo Pressing,)
This press machine can be used for interference fit pressing of engine rocker arm assembly inserts and rocker arms, combination of gasoline engine pistons and piston pins, interference fit pressing of bearings and bushings, pressing of motor rotors and rotating shafts, and various interference assembly applications in the automotive and motor industries. It is a high-performance, high-precision, and high-efficiency pressing and detection equipment.
Brief Overview of the Precision CNC Hydraulic Press Machine:
This machine uses an imported touch screen for data input and display, and an original American-made force sensor for pressure signal acquisition. The system can process pressure and displacement signals at a speed of 500 times per second, providing various alarms and curve plotting. Pre-set upper and lower limit curves for displacement and pressure can be compared with current pressing values. By inputting any pressing position, the interference resistance generated at that position during the previous pressing can be obtained.
What is Interference Fit:
An interference fit refers to a fit with interference (including minimum interference equal to zero). In this case, the tolerance zone of the hole is below the tolerance zone of the shaft (simply put, the shaft is larger than the hole, and during assembly, the shaft requires significant external force to be pressed in).
Product Features of the Precision CNC Hydraulic Press Machine:
1. Powered by liquid pressure of 2-20 MPa, with an external three-phase AC380V 50Hz or three-phase AC220V 60Hz power supply.
2. Uses liquid as the medium to transmit energy, equipped with an imported low-noise gear oil pump.
3. Employs a force sensor for direct measurement of pressing force, with an accuracy of ±5 N. The pressure signal control system uses digital signal transmission to ensure the accuracy of the force sensor is not compromised during transmission.
3. Noise levels during standby and slide movement do not exceed 75 decibels.
4. Features a robust open structure with integrated welding, ensuring sufficient rigidity of the machine body while providing convenient operating space.
5. Offers manual and semi-automatic control modes. Manual mode allows the pressing upper die to stop at any point within the stroke range, equipped with an emergency return button and infrared hand protection device.
6. The pressing stroke of this series of presses is transmitted to the programmable controller via a rotary encoder, automatically controlled by pre-written programs.
9. Pressure, stroke, pressure holding time, and closed height can all be adjusted by the customer on the touch screen.
10. The hydraulic system is built into the machine frame, giving it a neat, compact, and stable appearance.
12. The output force of this series of hydraulic machines is 5 tf, commonly referred to as 5 tons force (1 tf = 1000 kgf = 9.8 kN). Customization is available according to customer requirements.
