WHAT IS POWER PRESS MACHINE ?

As a fundamental machine tool in sheet metal processing, the power press machine is widely employed across industrial sectors for stamping operations, with most sheet metal components requiring die-compatible press processing. These versatile machines perform essential functions such as punching, bending, cutting, trimming, blanking, and forming. Among the variants, the crank-type power press demonstrates exceptional efficiency in high-speed blanking and stamping of thin to medium thickness sheet metal, owing to its swift cycle duration and accuracy. The eccentric gear press, distinguished by its extended stroke length, finds prevalent use in automotive part stamping and hot forging procedures. Meanwhile, the hydraulic press is particularly adept at deep drawing tasks, serving prominently in the production of motor housings and consumer goods like pots, cups, and tin cans. For large-scale applications, double crank, two-point and four-point eccentric gear presses—equipped with robust bolster plates—are optimally suited for processing extensive sheet metal components or supporting progressive die stamping workflows.

Want To Know The Different Advantages Of Different Power Press Machine?    

​​​​​​​Advantages

How does power press machine work?         

A press machine must operate in conjunction with a mold assembly, which typically consists of an upper punch rigidly mounted to the press ram and a lower die securely fastened to the press bolster. The electromechanical drive system initiates motion through the motor-driven flywheel, which transmits rotational force via the primary gear to the crankshaft. The crankshaft, in turn, actuates the ram through a precision-engineered connecting rod, while the ram's vertical movement is constrained by bronze-plated guide rails fixed to the machine frame. This mechanical configuration ensures the press delivers controlled force to the mold with exceptional positional accuracy. The system supports independent operation in either manual mode (single-cycle control) or automatic mode (continuous production cycles). For high-volume applications, multiple press units can be integrated with material handling transfer systems to form a fully automated production line, with synchronized motion control and interlocking safety features.

Do You Know How To Operate The Power Press machine Correctly?                        

Press Machine Operation Procedure‌
To begin, activate the main motor—the control panel indicator light will illuminate. Select the operating mode via the mode selector switch: Inches, Single, or Continuous. Set the air pressure to ‌0.5 MPa‌ and turn on the light curtain safety barrier switch.
In Inches mode, set the switch to Non-Continuous. Depress both hand buttons simultaneously to start the press. A single press initiates incremental movement, while continuous button pressure completes a full stroke.
For Single mode, ensure the ram is at ‌Top Dead Center (TDC)‌. Use either the two-hand buttons or foot pedal (selected via panel switch) to operate the press.
In Continuous mode, set the switch to Continuous. Depress both hand buttons until the crankshaft position indicator reaches ‌135°‌ (2–3 seconds), triggering automatic cycling. Press the emergency stop or continuous stop button to halt operation.
To adjust the slide, position the ram at ‌180° or 360°‌ (connecting rod vertical). Select Up or Down via the slide adjust switch, then press the adjust button to engage the ball screw for incremental ram movement.

POWER PRESS MACHINE MAINTENANCE

Press Maintenance Procedure‌
Daily maintenance‌ is critical for ensuring press longevity and safe operation. Operators must perform inspections before startup and after shutdown.
Pre-Startup Checks‌
. Verify ‌oil levels‌ in the gauge and ensure all lubrication points are adequately filled.
. Check ‌grease cups‌ for sufficient grease.
. Confirm ‌air pressure‌ ≥ ‌0.5 MPa‌.
. Test ‌solenoid valve‌ on the clutch for proper function.
. Start the ‌main motor‌ and verify ‌clockwise rotation‌.
. Test ‌emergency stop button‌ and ‌mode switches‌ for correct operation.
Post-Shutdown Procedures‌
. Power off‌ and disconnect electricity.
. Shut off‌ air supply.
. Drain moisture‌ from air lines to prevent water accumulation.
. Clean‌ the press thoroughly.
. Apply ‌rust-resistant oil‌ to exposed surfaces.
. Lock‌ the electrical cabinet and secure all operation keys.
This procedure ensures ‌prolonged press lifespan‌ and ‌operator safety‌.
