Structural features of crank press

Crank press is a kind of mechanical equipment commonly used in metal forming processing. Its main structural features are as follows:

Crank mechanism: The core part of the crank press is its crank mechanism, which is usually composed of a crank, a connecting rod and a slider. The crank drives the connecting rod, which in turn pushes the slider up and down to complete the pressure processing.

Body structure: The fuselage generally adopts cast iron or steel plate welding structure, which has high rigidity to withstand impact loads and pressure, and ensure working stability and accuracy.

Slider: The slider is an important working part of the press, which is used to achieve up and down reciprocating motion. It is connected to the crank mechanism for pressure output. The design of the slider must ensure its strength and accuracy.

Crankshaft and connecting rod system: The crankshaft transmits power to the connecting rod through rotation, forming the up and down movement of the slider. The shape and rotation angle of the crankshaft determine the movement trajectory and speed of the slider. The connecting rod is used to convert the rotational motion of the crankshaft into the linear motion of the slider.

Operating table: The operating table is the part of the press used to place the workpiece. It is usually equipped with a fixture or mold to fix the workpiece to ensure the stability and accuracy of the workpiece during processing.

Pressure regulation system: Crank presses are generally equipped with a pressure regulation system, which can adjust the pressure according to different processing requirements. This is very important for ensuring processing quality.

Flywheel: The flywheel is used to store and release energy, maintain the stability of the crank press during operation, and avoid speed fluctuations caused by load changes.

Lubrication system: Due to the large friction between the crank mechanism and the slider, the crank press is usually equipped with a lubrication system to reduce wear and ensure long-term stable operation.

Safety protection device: Crank presses are generally equipped with multiple safety protection devices, such as protective covers, safety doors, pressure overload protection, etc., to ensure the safety of operators.

In summary, the crank press converts the rotational motion into the linear reciprocating motion of the slider through the crank mechanism, and the structural design focuses on rigidity, precision and safety to achieve efficient metal forming operations.
