The Working Principle of Pneumatic Punching Machine

1、 Pneumatic punching machine uses pneumatic clutch to transmit the inertia force of flywheel to crankshaft, connecting rod and slider to work, the working principle is shown in the attached figure; the crankshaft connecting rod is rigid, so the movement of slider is compulsory, the number of trips and movement curve of slider are fixed at the same speed.

2、Use the high pressure gas generated by the compressor, the compressed gas is delivered to the solenoid valve through the pipeline, and the action of the solenoid valve is controlled by the foot switch to control the work and return of the cylinder, so as to achieve the purpose of punching.

3、Compressed air can be stored in the storage tank and taken at any time, so the motor has no idle energy waste. Using cylinder working parts, using solenoid valve as the control element makes the structure of this machine more simple, low failure rate, simple maintenance and lower maintenance cost.

Pneumatic punching machine, the brake method is pneumatic clutch, the main punching power comes from the motor driven flywheel, flywheel driven crankshaft, and the resulting punching force.

The main stamping power comes from the motor driving the flywheel and the flywheel driving the crankshaft, and the impulse is generated.

Ordinary punching machine, also called press, is a more traditional mechanical processing method for stamping process.

1. Pneumatic presses are higher in safety performance compared to traditional presses.
2. Pneumatic punching machines are more dense than traditional punching machines; it is easier to get on and off the die than traditional punching machines.
3. Pneumatic punching machines are faster than traditional punching machines; pneumatic punching machines have cylinders, which require air, while traditional ones do not.
4. The price of pneumatic punching machine is higher than that of traditional punching machine.

Features of pneumatic punching machine.
1, Using compressed air as the power source, and easy to operate, simple structure.
2, Adopt microcomputer control system, mode can choose manual, semi-automatic, fully automatic mode. Heating die, temperature control and pressure sensor can be added. Simple structure.
3, With anti-rotation guide bar and guide plate, high precision, can adapt to high-speed punching.
4, It can adjust the height, speed, stroke, pressure and stamping time arbitrarily according to different products or molds.
5, No noise generated by the standby of hydraulic system, which can save power consumption and reduce production cost.
6, Two-hand control or foot pedal can be chosen. Ensure the operator‘s personal.

Pneumatic punching machine is more hygienic and cleaner.

The use of advanced photoelectric protection technology can achieve a significant increase in safety performance, computerized counting and programming can achieve unattended processing process, greatly enhancing the efficiency of work and reducing the cost of production.

In the field of punching various metal and non-metal pipes and plates, most of them are completed by electric punching machines. Electric punching machines not only pollute the environment with high noise, their own complex structural components determine their high cost, difficult maintenance, high maintenance cost, bulky bodies, and consume much electricity.

The operation is complicated, the failure rate is high, and the safety hazard is great.

This machine has simple structure, low production cost, and adopts pneumatic technology to realize that one air compressor can be used for many pneumatic punching machines at the same time, which is more energy-saving than electric punching machines. Reduce electricity consumption loss.

Simple operation, higher safety, using a foot switch to control the solenoid valve, simple structure, low failure rate, improve production efficiency.
