S-160-2/S-160-2R Double Convoluted Rubber Bellows 98mm Height YOKOHAMA Air

Product Specification

S-160-2/S-160-2R Double Convoluted Rubber Bellows 98mm Height YOKOHAMA Air Spring Repalcement
 
Product Description
 
The GUOMAT F-160-2 press air spring is a high-performance solution designed to replace the original YOKOHAMA S-160-2, playing a crucial role as a "pneumatic balancer" in press equipment. This product achieves true direct replacement; its mounting interface, geometry, and key performance parameters are fully compatible with the original Yokohama parts, ensuring users can install and remove it immediately without any equipment modifications, significantly reducing maintenance downtime. During press operation, it uses the force generated by internal compressed air to precisely balance the weight of the heavy slide and die, effectively eliminating transmission system backlash, reducing impact vibration, and preventing accidental slide slippage during shutdown, thereby ensuring production safety, improving stamping accuracy, and protecting the core mechanical structure.

Applications of Air Springs in Punch Press Equipment

1. Balancing the Immense Weight of the Slide and Die
The slide, connecting rod, and upper die of a punch press are typically very heavy. Air springs, by filling with compressed air, generate a continuous and powerful upward thrust, precisely balancing this weight. The benefits of this are:

Reduced Drive Energy Consumption: The motor and transmission system do not need to overcome the entire weight, significantly reducing the torque and energy consumption required for operation.

Ensuring Smooth Operation: It avoids operational instability caused by the immense weight, making the slide's movement more controllable.

2. Eliminating Transmission System Clearance and Protecting Core Mechanisms
Small clearances exist between the crankshaft, connecting rod, and other mechanisms of a punch press. Without a balancing force, these clearances will generate significant impact and noise (commonly known as "knocking") due to the sudden change in force direction during the slide's downward movement. The upward force provided by the air spring ensures that the transmission mechanism maintains close contact throughout the entire working cycle, thereby:

Eliminating Impact and Noise: Greatly reducing equipment operating noise and improving the working environment.

Extending Equipment Lifespan: Effectively prevents wear and fatigue damage to core components such as bearings, gears, and crankshafts caused by gap impacts, extending the overall machine's service life.

3. Ensuring Operation and Maintenance Safety: This is a crucial safety function of air springs.

Preventing Accidental Slider Drop: When the equipment is stopped, molds are changed, or maintenance is performed, as long as a certain air pressure is maintained within the air spring, the slider can be reliably suspended in any position. This effectively prevents the slider from accidentally falling due to gravity, providing crucial safety assurance for operators and maintenance personnel.

4. Improving Stamped Product Quality: In high-speed precision stamping, even the slightest vibration can affect product accuracy.

Smoother Operation: By balancing weight and eliminating gaps, the slider's movement trajectory is more precise and smoother.

Reducing Vibration: Reduced vibration generated during operation is crucial for ensuring the contour accuracy of stamped parts and reducing burrs, especially critical in the manufacture of electronic components, precision connectors, and other products.
