(III) Easy Maintenance
- Simplified Friction Pad Replacement: Replacing friction pads is a straightforward process, requiring no disassembly of the clutch. This minimizes maintenance costs and time, enhances maintenance efficiency, and reduces equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: This extraordinary design dramatically enhances the product's heat dissipation capability, effectively lowering operational temperatures, extending the product's service life, and ensuring stability during prolonged high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: It boasts swift response times, enabling quick clutching and braking functions, meeting the demands of various mechanical applications for rapid response and boosting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with multiple connection methods, it can be flexibly configured to meet varied site requirements, offering strong adaptability and seamless equipment integration.


III. Product Structure
The pneumatic clutch brake is primarily composed of these essential components:
- Clutch Body: Mounted on the main shaft of the equipment, its center hole size is customizable to meet customer specifications (refer to the sample for available sizes). It is the pivotal component of the clutch system.
- Clutch Ear Plate and Brake Ear Plate: Expertly engineered to connect with the flywheel and machine body using four precision pins, these components guarantee a flawlessly stable operation of both the clutch and the brake, ensuring peak performance and reliability.
- Friction Pads (Blocks): These essential components are at the heart of the clutch and braking system, expertly managing the transmission and interruption of power with remarkable efficiency and precision.
- Clutch Pins, Brake Pins and Locking Plates: These elements are meticulously designed for the robust connection and secure fixation of various components. The locking plates are strategically embedded within pin grooves and securely fastened to the flywheel or machine body with screws, preventing any axial movement and ensuring stability.


IV. Working Principle
(I) Clutching Process
External compressed air enters the clutch cylinder through the intake hole, propelling the piston into action. This dynamic movement, combined with the high-performance friction pads, clutch body, and flat key, initiates the rotation of the driven part, achieving seamless clutch engagement and facilitating the smooth transmission of power.

(II) Braking Process
Upon cessation of air supply, the piston swiftly reverses direction under the powerful action of a spring. This rapid response, working in concert with friction pads, clutch body, and flat key, allows the driven part to be instantly braked. Remarkably, the braking time is a mere 0.01 - 0.02 seconds, ensuring the equipment halts with exceptional speed and precision.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The installation of the four pins demands a hole tolerance of H7. It is crucial that the hole centers remain perfectly parallel to the main shaft center, guaranteeing installation accuracy and enduring stability of the pins.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and surface roughness of the center hole and keyway are mandated to adhere strictly to national standards. Additionally, the customer's main shaft geometric tolerance and roughness should fulfill similar stringent requirements to optimize product performance.

(III) Installation Sequence Suggestions
Customers are advised to adapt the installation sequence to suit specific scenarios. Generally, one should begin with the installation of the clutch and brake ear plates, followed by pins and locking plates, and conclude with the clutch brake body for a streamlined process.

(IV) Installation Notes for Square Pins
Square pins are ingeniously utilized to correct any installation size discrepancies between two pins and to counteract thermal deformation of the plate caused by clutch heat. It is vital to ensure that the two flat surfaces of the square pin are aligned perfectly parallel to the radial direction of the ear plate for optimal efficacy.

(V) Sealing Requirements for Axial Air Intake
In cases involving axial air intake, it is imperative to install sealing caps at both ends of the clutch meticulously to prevent any gas leakage, thus maintaining system integrity.

(VI) Check after Installation
Post-installation, it is essential to verify that both the clutch end and brake end are capable of moving freely. This ensures the clutch and brake operate smoothly and effectively, delivering consistent performance and reliability.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Our High-Efficiency Clutch Brake Punching Machine has undergone rigorous quality checks to ensure it meets the highest standards. It is imperative that customers refrain from unauthorized disassembly of the clutch, as such actions may lead to damage for which we cannot be held accountable. Should you encounter any quality issues, please contact us immediately, and we pledge to address the matter promptly and efficiently.

(II) Friction Pad Replacement Method
Friction pads are essential yet consumable parts of our product, requiring replacement after extensive use when wear becomes significant. Fortunately, replacing these pads is straightforward, with no need to disassemble the ear plates or the clutch. Follow the steps outlined below for easy replacement:
- Replacement without Air Supply: First, gently loosen the clutch ear plate. Proceed by removing the bolts and nuts that secure the friction pads, replace them with new pads, and then ensure the bolts and nuts are securely tightened.
- Replacement with Air Supply: Begin by loosening the brake ear plate. Follow the previously mentioned steps to replace with new friction pads, ensuring a secure fit.

(III) Timing for Friction Pad Replacement
- For presses and similar machinery, inspect the friction pads whenever the machine struggles to meet its rated capacity to determine if replacement is required.
- Should the wear on the friction pads exceed 50% of their original state, a timely replacement is advised to maintain optimal performance.

VII. Product Selection
Selecting the right clutch is vital for maximizing the functionality of your equipment.
- Consequences of Improper Selection: A clutch that is too small cannot achieve the desired capacity, while an oversized one unnecessarily increases costs and causes overheating, hastening the wear of friction pads and aging of sealing rings.
- Selection Suggestions: Customers are encouraged to consult our comprehensive product samples or reach out to our expert technicians who can offer tailored, professional advice for selecting the most suitable clutch.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
To prevent any potential hazards, avoid any contact with the clutch during its high-speed rotation.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately post-operation, as it remains hot. Allow approximately half an hour for it to cool to room temperature before initiating any maintenance.

(III) Side Protection
Stay clear of the sides of a rotating clutch to prevent accidents from debris. It's recommended to install a protective cover over the clutch during use.

(IV) Attention during Ventilation Operation
During ventilation and air-stopping procedures, keep fingers away from the friction pads to prevent injury.

(V) Safety of Internal Structure
The clutch contains internal springs; unauthorized disassembly is hazardous and should be avoided. If disassembly is necessary, it must be performed by qualified professionals to ensure safety.
