(VI) Diverse Connection Methods
- Versatile Connection Choices: Equipped with a variety of connection methods, it offers flexibility to adapt to diverse site requirements, ensuring perfect compatibility with various equipment.


III. Product Structure
The pneumatic clutch brake is ingeniously comprised of the following key components:
- Clutch Body: Precisely mounted on the equipment's main shaft, its center hole dimensions can be customized to meet client specifications (refer to the sample for size range), serving as the pivotal component of the clutch.
- **Clutch Ear Plate and Brake Ear Plate**: These critical components are ingeniously connected to the flywheel and the machine body via four sturdy pins. This connection guarantees the unwavering stability and smooth operation of both the clutch and brake mechanisms, providing users with unparalleled reliability.
- **Friction Pads (Blocks)**: Serving as the heart of the clutching and braking process, these pads are essential for ensuring the seamless transmission and swift interruption of power, thereby enhancing the overall functionality and efficiency of the machinery.
- **Clutch Pins, Brake Pins, and Locking Plates**: These components are expertly designed for the precise connection and secure fixation of various parts. The locking plates, meticulously embedded within pin grooves and firmly secured to the flywheel or machine body with screws, effectively prevent any unwanted axial movement of the pins, ensuring optimal performance.


IV. **Working Principle**
(I) **Clutching Process**
External compressed air is skillfully directed into the clutch cylinder via the intake hole, propelling the piston into action. This sequence, in conjunction with the friction pads, clutch body, and flat key, orchestrates the smooth rotation of the driven part, effectively achieving clutch engagement and enabling flawless power transmission.

(II) **Braking Process**
Upon cessation of the air supply, the piston promptly reverses direction under the powerful influence of the spring. This action, through the friction pads, clutch body, and flat key, ensures the driven part is swiftly braked. The remarkably short braking time of just 0.01 - 0.02 seconds ensures the equipment's ability to halt with impressive speed and precision.

V. **Installation Requirements**
(I) **Hole Diameter and Parallelism Requirements**
The precise hole tolerance for the installation of the four pins must be H7. Additionally, the hole center should align perfectly parallel to the main shaft center, guaranteeing the meticulous installation accuracy and stability necessary for optimal equipment performance.

(II) **Geometric Tolerance and Roughness Requirements**
The geometric tolerance and surface roughness of both the center hole and keyway are strictly governed by national standards. Likewise, the geometric tolerance and roughness of the customer's main shaft must adhere to these rigorous standards to significantly enhance product performance and reliability.

(III) **Installation Sequence Suggestions**
Customers have the flexibility to adjust the installation sequence to suit their specific requirements. Typically, it is advisable to begin with the installation of the clutch and brake ear plates, followed by the pins and locking plates, and then proceed to the installation of the clutch brake body for optimal results.

(IV) **Installation Notes for Square Pins**
Square pins are a strategic choice to counteract installation size discrepancies between two pins and mitigate plate thermal deformation due to clutch heating. It is crucial to ensure that the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate for consistent and effective performance.

(V) **Sealing Requirements for Axial Air Intake**
For setups with axial air intake, it is imperative to install sealing caps at both ends of the clutch to effectively prevent any potential gas leakage, thus maintaining the integrity and safety of the system.

(VI) **Check after Installation**
Following the installation process, it is vital to ensure the free movement of both the clutch end and brake end. This check is essential to confirm the normal and seamless operation of the clutch and brake systems, securing peak performance and reliability.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch offered by Shandong Tenord Machinery Equipment Co., Ltd. is rigorously tested for quality assurance. Unauthorized disassembly by customers is strictly discouraged, as it voids responsibility for any resulting damages. Should any issues arise, promptly inform us, and our team will address them with utmost urgency.

(II) Friction Pad Replacement Method
The friction pads of the Precision Engineered Clutch Brake Punching Machine are essential components designed for wear and tear. When these pads show considerable wear from prolonged use, they should be replaced. Our innovative design allows for easy pad replacement without needing to disassemble the ear plates or clutch. The user-friendly steps are as follows:
- Replacement without Air Supply: Start by loosening the clutch ear plate. Remove the bolts and nuts securing the friction pads, then replace them with new ones. Finally, ensure all bolts and nuts are securely tightened.
- Replacement with Air Supply: Begin by loosening the brake ear plate and follow the same procedure outlined above to successfully replace the friction pads.

(III) Timing for Friction Pad Replacement
- For machinery such as presses, inspect the friction pads whenever the equipment fails to achieve its rated capacity to determine if replacement is needed.
- When the wear of the friction pads surpasses half the thickness of new ones, it is imperative for customers to perform timely replacements.

VII. Product Selection
Selecting the right clutch is vital as a key component of your equipment. It ensures optimal performance and longevity.
- Consequences of Improper Selection: Choosing a clutch that is too small won't fulfill the rated capacity, whereas an oversized clutch increases costs unnecessarily and risks overheating, expedited friction pad wear, and seal ring deterioration.
- Selection Suggestions: Customers are encouraged to reference our comprehensive product samples or consult directly with our technical experts. We are committed to offering guidance and professional recommendations tailored to your specific requirements.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
For your safety, refrain from making contact with the clutch or inserting objects while it's operating at high speeds to prevent accidents.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after use to prevent burns. Allow roughly 30 minutes for the clutch to cool down to room temperature before undertaking any maintenance activities.

(III) Side Protection
Positioning oneself beside a rotating clutch is hazardous due to potential flying debris. Ensure a protective cover is used to safeguard against accidents during operation.

(IV) Attention during Ventilation Operation
During ventilation or when halting airflow, keep fingers clear of friction pads to prevent entrapment hazards.

(V) Safety of Internal Structure
The clutch contains internal springs; unauthorized disassembly is strongly discouraged to prevent injury. If disassembly is necessary, it must be performed by qualified professionals.
