III. Product Structure
The pneumatic clutch brake consists of the following key components:
- Clutch Body: Installed on the equipment's main shaft, the center hole size is customizable to the client's specifications (refer to the sample for size range), serving as the clutch's main component.
- Clutch Ear Plate and Brake Ear Plate: Ingeniously engineered for excellence, these components are artfully connected to the flywheel and machine body, using four meticulously precision-engineered pins. This masterful connection ensures the smooth and stable operation of both the clutch and brake systems, elevating the performance of your machinery to new heights.
- Friction Pads (Blocks): As the backbone of the clutching and braking process, these indispensable components play a pivotal role, ensuring a seamless power transmission and precise power interruption. Their flawless operation guarantees a smooth transition every time.
- Clutch Pins, Brake Pins and Locking Plates: Serving as the linchpin of connectivity and security, the locking plates are masterfully embedded in the pin grooves. They are meticulously anchored to the flywheel or machine body with strategically placed screws, preventing any undesired axial pin movement and ensuring the highest level of operational stability.


IV. Working Principle
(I) Clutching Process
The clutching magic begins as external compressed air dynamically rushes into the clutch cylinder through the intake hole, setting the piston in motion. This orchestrates the friction pads, clutch body, and flat key to collaboratively rotate the driven part, achieving flawless clutch engagement and seamless power transmission that feels almost magical in its precision.

(II) Braking Process
In an intelligent interplay of mechanics, halting the air supply triggers the spring's force to propel the piston smartly in the reverse direction. The friction pads, clutch body, and flat key work in concert to swiftly brake the driven part in an astonishing 0.01 - 0.02 seconds, ensuring the equipment stops with unrivaled speed and efficiency.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Precision installation is key as the holes for the four pins adhere to an H7 tolerance, perfectly aligning their centers with the main shaft center. This ensures impeccable accuracy and unparalleled stability of the pins, laying the foundation for superior equipment performance.

(II) Geometric Tolerance and Roughness Requirements
Meeting the highest national standards, the geometric tolerance and surface roughness of the center hole and keyway are critical. Customers' main shafts must adhere to these rigorous standards, ensuring that the overall product performance and reliability are consistently top-tier.

(III) Installation Sequence Suggestions
For optimal installation success, customers enjoy the flexibility to choose the sequence based on specific scenarios. However, it's typically recommended to install the clutch and brake ear plates, pins, and locking plates first, followed by the clutch brake body, for achieving superior results.

(IV) Installation Notes for Square Pins
Ingeniously crafted, square pins are designed to counteract installation size discrepancies and thermal deformation due to clutch heating. It is essential that the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate, ensuring the highest operational integrity.

(V) Sealing Requirements for Axial Air Intake
To maintain pristine system integrity, axial air intake systems necessitate the installation of sealing caps at both ends of the clutch. This critical step effectively prevents any gas leakage, safeguarding the system's flawless function.

(VI) Check after Installation
After installation, it is crucial to ensure that both the clutch end and brake end move with effortless grace, guaranteeing the flawless and dependable operation of the clutch and brake systems, securing the machinery's peak performance.

(II) Friction Pad Replacement Method
The friction pads are crucial to the optimal functioning of our Heavy-Duty Clutch Brake Punching Machine for Eccentric Presses. These components are engineered for durability but will eventually necessitate replacement after significant usage. Our innovative design allows for an effortless replacement process, eliminating the need for disassembly of ear plates and clutches, thereby streamlining maintenance. Follow these comprehensively detailed steps to ensure continued peak performance:
- Replacement without Air Supply: Initiate the process by loosening the clutch ear plate. Remove the bolts and nuts securing the friction pads. Replace them with brand-new pads, ensuring a secure tightening of the bolts and nuts to maintain integrity and functionality.
- Replacement with Air Supply: This method mirrors the previous steps. Begin by loosening the brake ear plate. Carefully follow the outlined procedure to seamlessly integrate new friction pads, ensuring flawless operation and performance.

(III) Timing for Friction Pad Replacement
- In machinery such as presses, not reaching the rated capacity could indicate the need for friction pad replacement to restore optimal functionality.
- When friction pads are worn down to beyond half their original thickness, it becomes essential to replace them promptly to maintain high efficiency and safety in machine operations.

VII. Product Selection
Selecting the ideal clutch for your machinery is crucial as it has a significant impact on the success and lifespan of your equipment's operation. Choose wisely for optimum performance.
- Consequences of Improper Selection: Selecting a clutch that is too small can impede achieving the necessary capacity, while an oversized clutch may lead to unnecessary cost increases, overheating issues, accelerated friction pad wear, and faster deterioration of sealing rings.
- Selection Suggestions: Delve into our extensive collection of samples, or consult with our expert technicians for insightful guidance in choosing the clutch that perfectly aligns with your specific requirements. We are ready to provide you with professional recommendations that cater to your needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Your safety is our priority. It is imperative to avoid any contact with the operating clutch during high-speed rotations, as this poses significant risks. Adhere strictly to safety protocols to ensure your protection.

(II) Protection from High Temperature
After operation, the clutch remains extremely hot. Avoid direct contact to prevent burns. Allow approximately 30 minutes for cooling to ambient temperature before initiating any maintenance activities.

(III) Side Protection
To minimize risk from potential debris, never position yourself alongside a rotating clutch. Always ensure that a protective cover is securely installed during operation to safeguard against accidents.

(IV) Attention during Ventilation Operation
During ventilation or air stoppage procedures, it is crucial to maintain a safe distance from the friction pads to prevent injury from pinching accidents. Prioritize safety at all times.

(V) Safety of Internal Structure
The internal structure of the clutch contains springs, necessitating that only professionals undertake any disassembly. Unauthorized tampering can lead to personal injury and is strictly prohibited to ensure safety.
