The working principle of mechanical stamping press is based on the mechanical transmission system, which transmits power from the driving source to the working parts through the mechanical structure, thereby realizing the processing processes such as stamping and forming.
Main working steps and principles:
Starting drive source
The power of a mechanical stamping presses is usually provided by an electric motor, which transmits power to the main machine through transmission devices such as belts, gears, and flywheels.
The rotation of the motor drives the flywheel or gear to rotate, accumulating a certain amount of kinetic energy.
Flywheel energy storage
The flywheel is a key component in a mechanical stamping press, which is driven to rotate by an electric motor.
The function of the flywheel is to store energy and release it during the working process. The flywheel accumulates energy by rotating. When the press starts working, the flywheel releases the stored energy and drives the punch of the press downward.
Punch Movement
The energy of the flywheel is transferred to the main drive system, which converts the rotational motion into reciprocating motion through a set of gears, crankshafts and other components. The crankshaft converts the rotational motion into linear motion, driving the punch up and down. When the punch descends, it contacts the workpiece and applies pressure, causing the workpiece to deform or cut, etc.
Pressure and Forming
During the downward process, the punch exerts huge pressure on the workpiece, causing the material to undergo plastic deformation, completing the processing of stamping, bending, stretching, etc. As the punch continues to descend, the die on the worktable contacts the workpiece to complete the forming or cutting.
Rebound and return
After the work is completed, the energy of the crankshaft and flywheel helps the punch to rise back. When the punch rises, the energy released helps it return to its initial position to prepare for the next punching.
While the punch is rising, the high-speed mechanical stamping press waits for the next operation until a new workpiece is ready to be placed.
Repetitive Operations
Mechanical power presses are capable of repeating these actions at relatively high speeds, performing rapid punching or forming work. These presses are suitable for high-volume production, especially simple, repetitive punching and forming tasks.
Main components:
Motor: Provides driving power.
Flywheel: Stores kinetic energy and helps release power smoothly.
Crankshaft and gears: Convert rotational motion into reciprocating motion.
Punch: Used to apply pressure to the workpiece to complete the processing.
Workbench and die: Support the workpiece and provide the shape for forming or cutting.
Brief introduction of working process:
The motor starts and drives the flywheel to rotate.
The flywheel stores energy and the transmission system transfers the energy to the punch.
The punch descends to apply pressure to complete the stamping, forming and other processes.
The punch rises to prepare for the next operation.
The whole process is carried out in a repeated cycle.
Simple and stable mechanical stamping press, suitable for large-scale and high-speed production.
