Single crank semi-closed press is a common mechanical press, which is widely used in metal processing, stamping, forming, stretching and other processes. Its working principle is to drive the crankshaft to rotate through a mechanical transmission system, and apply pressure to the workpiece through a pressure plate to complete the corresponding processing process. The specific working principle is as follows:
1. Main structure
Crankshaft: It is the core part of the press, driven by an electric motor, and uses the rotational motion of the crankshaft to transmit mechanical energy.
Pressure plate: The part that applies pressure, connected to the slider of the crankshaft.
Slider: Connected to the crankshaft and moves up and down with the pressure plate to apply pressure to the workpiece.
Transmission system: includes an electric motor, gearbox, belt or other form of transmission device, which is used to transmit the power of the motor to the crankshaft.
2. Working principle
Starting and rotating: After the motor is started, the power is transmitted to the crankshaft through a belt or gear. The crankshaft starts to rotate and transmits motion through the connected slider system.
Pressing the workpiece: When the crankshaft rotates, the slider moves up and down driven by the crankshaft. The movement of the slider will be applied to the workpiece through the pressure plate. The pressure plate applies pressure to the workpiece by moving downward to complete the required processing action.
Semi-enclosed structure: The single crankshaft semi-enclosed press adopts a semi-enclosed structure, which means that the working part of the press is partially covered to improve safety, reduce the leakage of oil or metal chips, and also help protect the operator from damage by mechanical parts.
Release pressure: When the crankshaft rotates to a specific position and the slider completes the workpiece pressing task, the pressure plate stops applying pressure and the slider returns to the initial position to prepare for the next round of processing.
3. Features and advantages
High efficiency: The single crankshaft semi-enclosed press has a simple structure, high power transmission efficiency, and can complete processing tasks quickly.
Strong impact force: Due to the use of crankshaft drive, it can provide a large impact force, which is very suitable for high-intensity stamping work.
Safety: The semi-enclosed structure protects the operator and reduces safety hazards during work.
Wide adaptability: It can be widely used in metal stamping, die forming, cold processing and other industries.
4. Common applications
Stamping: Punching and forming metal.
Deep drawing: stretching metal sheets into shape.
Mold processing: providing precise forming and pressing processes for parts manufacturing.
In general, the single crankshaft semi-enclosed press uses a simple and effective mechanical transmission system to drive the slider up and down by the rotation of the crankshaft, thereby applying pressure to the workpiece to complete stamping, forming and other processing tasks.
