Introduction
The J23-80 puncher press machine is a general punch machine used for pressing sheet metal, which is commonly used in watch, toys, tableware, telecommunications, instrumentation, electrical machine, automobile making and so many other fields.
When the press machine is equipped with the automatic feeding device, it can carry out semi-automatic pressing. The nominal force of the equipment occurs 5mm distance from the slider to bottom dead center. In the design of cold pressing process, the working rules are selected according to the pressure curve diagram. When selecting, the intersection between use pressure and corresponding crank angle must be within the scope of strength.

Description
J21-100 punch presses are large machines with a c type frame, power press with fixed bed and slide block's reciprocating motion to finish the punching work. It is usually used for stamping and forming communications, computers, household appliances, furniture, vehicles(cars, motorcycles, bicycles metal parts), etc.
Characteristics
1.It adopts steel welding structure with high stiffness and reasonable structure and low noise.
2.Combined type air friction clutch which is easy to install and repair.
3.The main motor have positive inversion function and with duplex magnetic valve to ensure the safety.
4.The crank connecting rod serves as the working mechanism. Crank connecting rod is rigid, so the movement of the slider is mandatory, times of strokes in per minute of slider and the movement curve of the slider are fixed.

Introduction
The puncher is a general punch machine used for pressing sheet metal,which is suitable for cold pressing,such as shearing,punching,blanking,bending and shallow drawing,but it is not suitable for stamping.The body of the press machine can be tilted so as to facilitate the finished products falling down from the die.
Features
1.Large operation space,and the movable bolster could be moved out of frame to set
the die. The structure is simple and the appliance is also beautiful.
2.The machine adopts double safety valve to ensure the accurate implementation of the clutch instruction.
3.It has both hands button and foot switch to achieve continuous,single and inching practices.
4.Electrical components are in accordance with international standards,reliable safety,long life,good anti-interference ability,a radiation unit is fitted in electrical cabinet.
