Pneumatic punch press uses a pneumatic clutch to transmit the inertia force of the flywheel to the crankshaft, connecting rod, and slider for operation; The crankshaft connecting rod is rigid, so the motion of the slider is mandatory. At the same speed, the number of strokes and motion curve of the slider are fixed and unchanged.
technical field
Pneumatic punching machine is a universal machinery in the stamping industry, suitable for cold stamping work such as punching, dropping, bending, and stretching of various metal and non-metal pipes and plates (not used for pressing and printing work). Equipped with a feeding mechanism, it can perform semi-automatic or fully automatic work, and is equipped with photoelectric protection to reduce occupational injuries. Compressed air can be stored in air storage tanks and accessed at any time, so there is no energy waste from the motor idling. By using cylinders as working components and solenoid valves as control elements, the structure of this machine is simplified, with low failure rates, high safety, simple maintenance, lower maintenance costs, and high production efficiency. Using a 220V power supply to control the solenoid valve is simple and convenient to operate.
In the field of punching various metal and non-metal pipes and plates, electric punching machines are mostly used. Electric punching machines not only have high noise pollution, but also have complex structural components that determine their high cost, difficult maintenance, high maintenance cost, bulky body, and high power consumption. The operation during work is complex, with a high failure rate and significant safety hazards.
working principle
Using the high-pressure gas generated by the compressor, the compressed gas is transported to the solenoid valve through the pipeline, and the action of the solenoid valve is controlled by the foot switch to control the operation and return of the cylinder, thereby achieving the purpose of punching holes. Compressed air can be stored in air storage tanks and accessed at any time, so there is no energy waste from the motor idling. Using cylinders as working components and solenoid valves as control elements makes the structure of this machine simpler, with lower failure rates, easier maintenance, and lower maintenance costs. Using a 220V power supply to control the solenoid valve is simple and convenient to operate.
