Precision power press is a kind of equipment widely used in precision machining, forming, stamping and other fields. Its working principle is mainly based on the transmission and pressing process of force. The following is a brief introduction to its basic working principle:
1. The power source of precision power press is usually an electric motor, which transmits power to the main part of the press through the transmission system. The motor controls the rotation of the main shaft of the press, and then drives the pressure head up and down.
2. In the precision power press, the motor converts the rotating power into linear motion through a set of precise mechanical transmission systems. The core components of the system include:
Flywheel: used to store and release energy to ensure the smooth operation of the press.
Crank slider mechanism: converts the rotational motion of the motor into the up and down reciprocating motion of the slider, which is the key moving part of the press.
Slider: The slider moves vertically under the action of the crank and applies pressure to the material through the transmission system.
3. When the power system is started, the slider starts to move up and down. When the slider goes down, it drives the mold to perform pressing or forming operations, applying a concentrated and strong pressure on the workpiece or mold to achieve the desired forming or stamping effect.
4. One of the key features of precision power presses is its high-precision control system. The accuracy of pressure is ensured in the following ways:
Adjusting pressure system: The pressure can be adjusted through hydraulic systems or mechanical devices to ensure that the pressure on the workpiece meets the processing requirements.
Position sensor and feedback system: The position of the slider is monitored by sensors, and the accuracy of the slider movement is adjusted in real time to ensure the high consistency of each stamping and forming process.
5. In order to ensure precision and avoid vibration, precision power presses are usually equipped with a shock absorption system. The shock absorption system can reduce the vibration during equipment operation and make the workpiece subject to more stable force during processing.
6. In order to ensure the safety of operators, precision power presses are usually equipped with a series of safety protection mechanisms, such as:
Emergency stop device: When an abnormal situation occurs, the machine can be stopped quickly.
Safety door and photoelectric protection: Ensure that the operator will not have an accident due to contact with dangerous areas.
Summary: The working principle of the precision power press is to drive the mechanical transmission system through an electric motor to convert the rotary power into the reciprocating linear motion of the slider, thereby applying high-precision and high-intensity pressure for processing. Its high precision and high efficiency make it widely used in the fields of precision forming, stamping and processing.
