Composition of mechanical punch press

Mechanical punch press is a precision equipment that uses a mechanical transmission system for stamping processing.Its composition mainly includes the following key parts:
1、Body
The body is the main structure of the mechanical punch press,carrying other components such as the crankshaft,slider,transmission shaft,etc.It provides a guide rail for the up and down movement of the slider,ensuring the accuracy and stability of the stamping stroke.The body is usually made of sturdy materials to withstand the tremendous force during the stamping process.
2、Transmission system

The transmission system is responsible for transmitting the power of the power source to the various working components of the punch press.It usually includes components such as electric motors,pulleys,drive shafts,small gears,and large gears.The electric motor transmits power to the drive shaft through a pulley,which in turn drives the small gear to rotate.The small gear meshes with the large gear,transmitting power to the crankshaft and driving the slider to complete the stamping action.

3、Crank mechanism
The crank mechanism is a key component in the punch press,responsible for converting rotational motion into the up and down reciprocating motion of the slider.It usually includes components such as crankshaft,connecting rod,and slider.The crankshaft rotates under the drive of the transmission system,and the rotational motion is converted into linear motion of the slider through the connecting rod.This process promotes the stamping processing of mechanical punch presss,enabling the slider to efficiently complete reciprocating linear motion,thereby driving the punch to perform diversified processing on workpieces,such as stamping,forming,and shearing.
4、Clutch
The clutch is used to control the punching and stopping of the punch press.It is usually located between the transmission system and the crank mechanism,transmitting or cutting off power through engagement or disengagement.There are various designs and types of clutches,such as rotary key rigid clutches and pneumatic friction plate clutches,to adapt to different stamping requirements and working environments.
5、Brake system
The brake is used to act instantly after the clutch is disengaged,blocking the inertia of the crankshaft(including the slider)and ensuring that it accurately stops at the top dead center position.This is crucial for ensuring stamping accuracy and safety.
6、Mold adjustment device
The mold adjustment device is used to adjust the position and height of the mold on the mechanical punch to ensure the correct fit between the mold and the workpiece during the stamping process.It usually includes components such as adjusting screws and mold pads,which can easily adjust the height and tilt angle of the mold.
7、Balance device
The balancing device is used to reduce the vibration and impact force generated by the punching machine during the stamping process,and improve the stability and service life of the equipment.It usually includes components such as counterweights and shock absorbers,which can effectively balance the inertial force generated by the slider during its up and down movement.
8、Overload device
Overload device is a safety protection device for mechanical punch presss,used to prevent equipment overload during the punching process.When the punching force exceeds the nominal pressure,the device will trigger to protect the press from damage.It usually includes components such as fuses,which can be selected and adjusted according to actual needs.
9、Electrical control part
The electrical control part is used to control the start,stop,speed regulation,and fault alarm functions of the punch press.It usually includes components such as an electrical control box,buttons,indicator lights,etc.,which can facilitate the automation control and monitoring of mechanical punch presss.
10、Lubrication section
The lubrication part is used to lubricate the various moving parts of the mechanical punch press,in order to reduce friction and wear,and improve the operating efficiency and service life of the equipment.It usually includes components such as lubricating oil tank,oil pump,oil pipe,etc.,which can ensure that all moving parts receive sufficient lubrication and cooling.
In summary,the composition of mechanical punch presss is complex and precise,and the various components work together and collaborate to complete the stamping processing task.
