What is the difference between mechanical press and hydraulic press?

Choosing the right type of punch machine for your manufacturing needs is critical to improving the efficiency, accuracy and reliability of your production. As a press manufacturer with over 10 years of experience in the industry, today we would like to introduce to you what the difference is between a mechanical press and a hydraulic press to help you make a better choice.

1.Mechanical Punch Press

(1) What is Mechanical Punch Press

Mechanical Punch Press is a kind of equipment that uses mechanical transmission system to carry out stamping processing, cutting, punching, and stretch forming of metal plates or wires by means of molds, and converting rotary motion into linear motion of slider to realize accurate stamping.

(2) Advantages of Mechanical Punching Machine

High speed and high precision: the processing speed of mechanical punching machine can reach more than 400 times per minute, which is suitable for mass production.

Lower 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 workshop.

(3) Disadvantages of Mechanical Punching Machines

Safety Risks: There are certain safety hazards, easy to cause accidents, need to be equipped with protective measures and strict training of operators.

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

2. Hydraulic Press

(1) What is a hydraulic press

Hydraulic press is a pressure processing equipment with hydraulic system as the power source, which realizes the stamping process by generating compression force through hydraulic cylinders, and is widely used in the field of metal forming.

(2) Advantages of Hydraulic Press

Convenient operation: no need to vigorously rotate the crank during operation, just press the button to work.

Adjustable pressure: to adapt to different materials and process requirements.

High efficiency: ensure the processing quality during processing, realize automatic production and improve processing efficiency.

(3) Disadvantages of Hydraulic Punch Press

High maintenance cost:The hydraulic system requires regular maintenance to prevent oil leakage.

Sensitive to the environment: performance may be affected under extreme temperatures.

3. Differences between mechanical presses and hydraulic presses

(1) Structural differences

There is a big difference between the structural forms of hydraulic presses and mechanical presses. Mechanical punch press adopts mechanical transmission device, through the clutch, reducer, connecting rod and crank and other transmission mechanism to realize the stroke. While the hydraulic press adopts hydraulic transmission device, it pushes the hydraulic oil to the plunger through the hydraulic oil pump to realize the downward movement of the ram.

(2) Difference in working principle

Mechanical punch press works by converting the rotating motor's into cutting kinetic energy through clutch, crank and linkage transmission mechanism to complete the cutting work. Hydraulic punch press is through the hydraulic cylinder and hydraulic system pressure to drive the cam slider downward movement, and punching die will be punching materials. Hydraulic punch press in the working process noise is relatively small, can better control the processing accuracy.

(3) Difference in precision

Hydraulic press adopts hydraulic transmission device, which has the advantages of stable punching force, accurate stroke and high processing precision. Mechanical punching machine adopts mechanical transmission device, due to the mechanical transmission force along the main axis to change, resulting in relatively poor working accuracy of the punching machine.

(4) Comparison of production efficiency

The processing speed of mechanical press is relatively fast, which is suitable for mass production. Although the processing speed of hydraulic press is slower, but the processing quality is more stable, which can better meet the requirements of product quality.

(5) Comparison of maintenance costs

Hydraulic presses have higher maintenance costs than mechanical presses, and the maintenance and repair of the hydraulic system requires the maintenance of oil pipes, oil pumps and other components, which is also more demanding for maintenance personnel.

In conclusion, mechanical presses and hydraulic presses have their own advantages and are suitable for different applications. Mechanical presses are ideally suited for high-speed, high-volume production with consistent results, while hydraulic presses offer adjustable pressure and precise control for complex tasks.
