What is the punching machine called?

The official name of a punching machine is "punching machine", also known as a press machine, which is a mechanical equipment that applies pressure to metal or non-metal materials to cause plastic deformation or separation, thereby obtaining the desired shape and size of stamped parts. Here is an introduction to the punching machine:

1.Definition and purpose

The punching machine drives the flywheel through an electric motor and drives the gears, crankshaft (or eccentric gear), connecting rod, etc. through a clutch to achieve linear motion of the slider. The motion from the main electric motor to the connecting rod is circular motion. It is widely used in stamping and forming fields such as electronics, communication, computers, household appliances, furniture, transportation vehicles (automobiless, motorcycles, bicycles), hardware components, etc.

2.Structural composition

It mainly consists of the body, transmission system, working mechanism, control system, lubrication system, and other parts. The body is the foundation of the punching machine, providing installation support for other components; The transmission system transfers the power of the electric motor to the working mechanism; The slider and mold in the working mechanism are key components for achieving stamping processing; The control system is used to control the operation of the punching machine; The lubrication system ensures the normal operation of all components and reduces wear.

3.Working principle

When the punching machine is working, the electric motor drives the flywheel to rotate, and the power is transmitted to the crankshaft through the clutch, causing the crankshaft to make circular motion. The crankshaft converts circular motion into linear reciprocating motion of the slider through the connecting rod. The slider drives the upper mold to move downward and cooperates with the lower mold to apply pressure to the material placed between the molds, causing plastic deformation or separation, thus completing the stamping process.

4.Type and Characteristics

1. Mechanical punching machine: Using an electric motor to drive a flywheel, the rotating motion is converted into linear reciprocating motion of a slider through transmission mechanisms such as clutches, gears, and crankshafts. Its characteristics are simple structure, reliable performance, and easy operation, suitable for processing various small and medium-sized stamping parts.
2. Hydraulic punching machine: Using hydraulic oil as the working medium, mechanical energy is converted into hydraulic energy through a hydraulic pump, and then the hydraulic energy is converted into linear motion of the slider through a hydraulic cylinder. It has the advantages of high pressure, smooth operation, and low noise, and is commonly used in stamping processing of large and thick plate materials.
3. Pneumatic punching machine: powered by compressed air, the slider is driven to move by a cylinder. It has the characteristics of fast response speed, energy saving and environmental protection, and is suitable for occasions with high requirements for stamping speed and low stamping pressure.
4. High speed punching machine: It has the characteristics of high precision and high efficiency, and can complete a large number of stamping tasks in a short time, suitable for precision stamping processing in industries such as electronics and electrical appliances.
Punching machines, which play a key role in the manufacturing industry, shine in the fields of stamping and forming of metal and non-metal materials under the name of "punching machine" or "press machine". It meets the needs of different industries and scales of production with its unique structural composition, working principle, and diverse type characteristics. From the reliable and practical use of mechanical punching machines, to the powerful and stable performance of hydraulic punching machines, to the fast and energy-saving performance of pneumatic punching machines, and the high efficiency and precision of high-speed punching machines, the continuous development and innovation of the punching machine family have injected a continuous stream of power into the progress of the manufacturing industry. I believe that in the future, punching machines will continue to write brilliant chapters on the industrial stage, helping various industries move towards higher quality development stages.
