What is the difference between pneumatic and mechanical press?

As one of the key equipment in the metal processing industry, punch presses are widely used in a variety of processes. As a manufacturer of punching machine equipment with 10 years of industry experience, we are well aware of the differences between different equipment. In this article, we will systematically compare the differences, advantages and disadvantages of pneumatic punching machines and mechanical punching machines from a professional point of view, which will help you make a more reasonable and efficient purchasing plan.

1.Comparison of working principle

Pneumatic punch press: the punching force comes from the impulse generated by the up and down movement of the cylinder. It is through the high pressure gas produced by the compressor, through the pipeline to the solenoid valve, and through the foot switch to control the action of the solenoid valve, so as to control the work of the cylinder and return to achieve the purpose of punching.

Mechanical punch press: The punching pressure comes from the punching pressure generated by the crankshaft rotation. It is punched by the motor driving the pulley and the punch flywheel using inertia. Mechanical power is used to drive the punch to impact up and down to realize the processing of metal materials.

2. Scope of application difference

pneumatic press is widely used in light sheet, small sheet or small batch production occasions, because of its faster speed, energy saving and environmental protection, low noise, more suitable for small sheet processing. The mechanical press is usually applied to medium and large plate manufacturing or mass production of processing occasions, because its power is larger, higher impact strength, suitable for processing thick plates.

3. Pneumatic press advantages and disadvantages

Advantages:

(1) Fast speed: pneumatic punching machine is fast in the processing, can quickly complete the parts processing.

(2) High precision: the pneumatic press has high precision and can meet various precision requirements of parts processing.

(3) Good stability: Since the pneumatic punch press adopts pneumatic device, it has the advantage of good stability when working and can meet the processing requirements.

(4) Wide applicability: pneumatic punching machine is suitable for the processing of metal parts and can be widely used in various manufacturing fields.

Disadvantages:

(1) Noisy operation: because of the need to produce a large pneumatic sound when working, the noise is one of the shortcomings of the pneumatic punch press that needs to be improved.

(2) High cost of equipment: Since pneumatic punch press adopts pneumatic device, high cost is also one of the disadvantages of pneumatic punch press.

4.Advantages and Disadvantages of Mechanical Punching Machines

Advantages:

(1) High speed and high production: the processing speed of mechanical press can reach more than 400 times per minute, which can ensure the quiet environment of production workshop.

(2) Low noise: compared with other types of punching machines, the noise of mechanical punching machines is very small, which can ensure a quiet environment in the production plant.

(3) Simple operation: the operation of mechanical press is relatively simple, only need to carry out simple manual operation, can realize efficient processing.

(4) Cost-effective: compared with CNC punch press, the cost of mechanical punch press is relatively low, which can meet the metal processing needs of small and medium-sized enterprises.

Disadvantages:

(1) Safety hazards: mechanical punching machines have a little bit of safety hazards, if not operated properly, it is very easy to cause accidents.

(2) Easy to wear: the punch of the mechanical press is easy to wear, and needs to be replaced regularly.

(3) Complicated maintenance: the maintenance of mechanical presses requires a high level of skill and is difficult to maintain.

(4) Prone to jamming phenomenon: when encountering very hard materials in the process, or when there is an overload situation, the mechanical press is prone to jamming phenomenon, which affects the processing efficiency.

5. Precautions for choosing punching machine

(1) Choose the press according to the processing material, choose the mechanical press suitable for thick plate processing, choose the pneumatic press suitable for thin plate processing.

(2) According to the production of choice of punching machine, if it is mass production, choose mechanical punching machine is suitable; if it is small-scale production, choose pneumatic punching machine is more suitable.

(3) According to the price of the equipment to choose the right punch press, do not blindly pursue high-end equipment, but according to their own actual situation and production to choose the right punch press equipment.

To sum up, pneumatic punching machine and mechanical punching machine have their own characteristics, when choosing punching machine equipment, you need to consider according to their own production needs, processing materials and other factors, choose the right equipment to achieve the best processing results and economic benefits.
