(III) Easy Maintenance
- Effortless Friction Pad Replacement: The friction pads are easily replaceable without disassembling the clutch, significantly reducing maintenance costs and time, boosting maintenance efficiency, and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: The innovative disc arc design dramatically enhances heat dissipation, lowering operational temperatures, prolonging product life, and ensuring equipment stability during prolonged high-load usage.
(V) Quick Response
- Rapid Clutching and Braking: Featuring a swift response time, it effortlessly achieves clutching and braking functions, satisfying the rapid response requirements of various machinery and elevating production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with a variety of connection methods, it offers flexibility to match different site requirements, showcasing exceptional adaptability and compatibility with a broad range of equipment.


III. Product Structure
The pneumatic clutch brake is primarily composed of these vital components:
- Clutch Body: Mounted on the main shaft of the equipment, the center hole size can be tailored to customer specifications (refer to the sample for size range), and it serves as the clutch's fundamental component.
- Clutch Ear Plate and Brake Ear Plate: Ingeniously designed to connect seamlessly to the flywheel and machine body of the equipment through four robust pins. This sophisticated assembly guarantees the unwavering stability and smooth operation of both the clutch and brake, ensuring optimal performance.
- Friction Pads (Blocks): As a pivotal element in the clutching and braking process, these friction pads expertly manage the transmission and interruption of power, delivering exceptional control and precision.
- Clutch Pins, Brake Pins and Locking Plates: Essential components for the secure connection and fixation of various parts. The locking plates are strategically embedded in pin grooves and firmly secured to the flywheel or machine body with screws, effectively preventing any axial shift of the pins, thus enhancing durability and reliability.


IV. Working Principle
(I) Clutching Process
As external compressed air channels into the clutch cylinder, it propels the piston forward. This dynamic action, transmitted through the friction pads, clutch body, and flat key, seamlessly engages the driven part, culminating in a flawless clutch engagement that facilitates power transmission.

(II) Braking Process
Upon cessation of the air supply, the piston retracts under the spring's influence. Through the friction pads, clutch body, and flat key, this action ensures the swift braking of the driven part within a mere 0.01 to 0.02 seconds, delivering a rapid and reliable stop to the equipment.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Precision is paramount with a hole tolerance set at H7, and the alignment of the hole center parallel to the main shaft center is crucial. This meticulous attention to detail guarantees the impeccable installation accuracy and stability of the pins, promising long-term operational excellence.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and surface roughness of the center hole and keyway are rigorously aligned with national standards. Simultaneously, the customer's main shaft must adhere to these stringent requirements, elevating the product's overall performance and reliability.

(III) Installation Sequence Suggestions
Installation can be tailored to specific needs, but generally, it is advisable to initially set up the clutch and brake ear plates, along with pins and locking plates, before progressing to the installation of the clutch brake body for maximum efficiency and effectiveness.

(IV) Installation Notes for Square Pins
Square pins are ingeniously designed to counteract installation size discrepancies between two pins and offset the plate's thermal deformation due to clutch heating. Ensure that the two flat surfaces of the square pin align parallel to the radial direction of the ear plate for optimal functionality.

(V) Sealing Requirements for Axial Air Intake
For an axial air intake configuration, the installation of sealing caps at both ends of the clutch is paramount to prevent any potential gas leakage, safeguarding the system's integrity and efficiency.

(VI) Check after Installation
Post-installation, it is imperative that both the clutch end and brake end are able to move freely. This ensures the seamless and uninterrupted operation of the clutch and brake, underpinning the machinery's reliability.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch sold by Shandong Tenord Machinery Equipment Co., Ltd. has been rigorously tested for quality assurance. Customers must refrain from unauthorized disassembly, as any damage incurred from such actions will not be covered by our company. Should you encounter any quality issues, please promptly notify us so that we can address and resolve them with the utmost urgency.

(II) Friction Pad Replacement Method
The friction pads are integral consumable components of our High-Quality Clutch Brake Punching Machine for Deep Drawing Presses. With extended usage, these pads may wear down significantly, necessitating their replacement. Our design ensures that replacing these friction pads is straightforward and does not require the disassembly of ear plates or the clutch itself. Here is the detailed procedure:
- Replacement without Air Supply: Start by loosening the clutch ear plate, then remove the bolts and nuts securing the friction pads. Proceed by installing the new friction pads, and finally, secure the bolts and nuts firmly.
- Replacement with Air Supply: Begin by loosening the brake ear plate, then follow the aforementioned steps to replace the worn friction pads with new ones.

(III) Timing for Friction Pad Replacement
- In machinery such as presses, if the machine fails to achieve its rated capacity, it may indicate an urgent need to assess the condition of the friction pads for potential replacement.
- When the wear on the friction pads surpasses half the thickness of new pads, it's imperative for customers to perform a timely replacement to ensure optimal performance.

VII. Product Selection
Selecting the right clutch is vital for ensuring the optimal function of your machinery. It is crucial to choose wisely.
- Consequences of Improper Selection: Selecting a clutch that is too small will prevent the machine from achieving its rated capacity. Conversely, an oversized clutch can lead to unnecessary expenses, overheating, accelerated friction pad wear, and premature aging of sealing rings.
- Selection Suggestions: Customers are advised to refer to our company's samples or consult our expert technicians. We are committed to providing insightful and professional guidance to aid in your selection process.

VIII. Safety Precautions
(I) Protection during High-Speed Rotation
For your safety, avoid any contact with the clutch while it is spinning at high speeds to prevent accidents.

(II) Protection from High Temperature
Refrain from touching the clutch directly with bare hands immediately after it ceases rotation, as it may still be hot. Allow approximately thirty minutes for the clutch to cool to room temperature before conducting maintenance tasks.

(III) Side Protection
Standing beside a rotating clutch is strictly prohibited to prevent accidents due to flying debris. It is essential to install a protective cover over the clutch during operation for enhanced safety.

(IV) Attention during Ventilation Operation
During the ventilation and air-stopping phases, avoid touching the friction pads with your fingers to prevent the risk of injury from being pinched.

(V) Safety of Internal Structure
The clutch contains internal springs, and it is crucial to avoid unauthorized disassembly to prevent injury. If disassembly is necessary, it must be conducted by qualified professionals only.
