Product Description

Product Manual for Dry Multi-Disc Pneumatic Clutch Brake for Punch Press  
 1. Product Overview  
This product is a dry multi-disc pneumatic clutch brake, specifically designed for high-tonnage punch presses, die-cutting machines, cold heading machines, and other forging equipment. It aims to provide high clutch torque or braking torque (or both simultaneously) while addressing spatial constraints. The product utilizes asbestos-free friction materials and integrates pneumatic control for rapid engagement/disengagement and precise braking. The AS series is compatible with mainstream forging equipment brands (e.g., Yangli, Yangduan, Shanghai Erduan). Installation configurations include: single clutch with dual brakes, dual clutches with single brake, and dual clutches with dual brakes. For specific requirements, contact us for professional selection and recommendations based on your equipment needs.  

AS0250 Multi-Disc Pneumatic Clutch Brake

Outer Diameter: 352 mm

Weight: 37 kg

Maximum Speed: 1750 rpm

Single Disc Maximum Clutch Torque: 1570 N·m

Single Disc Maximum Braking Torque: 1850 N·m

Torque Doubling: When two discs are assembled, the torque doubles (clutch: 3140 N·m / brake: 3700 N·m).

 2. Structure and Working Principle  
 1. Core Components  
- Main parts: Clutch body, piston, brake spring, friction plates, clutch ear plate, brake ear plate.  
- Transmission method: Connects to the spindle via a flat key, transmitting torque through friction disc sets.  
 2. Working Principle  
- Clutch engagement: Compressed air enters the cylinder through the axial bore, pushing the piston to compress the brake spring. The friction plates are pressed together to transmit power.  
- Braking process: When air supply is cut off, the spring resets, forcing the piston to reverse. The friction plates press against the brake disc for rapid braking.  

 

 3. Technical Features  
1. High Efficiency & Reliability  
   - Compact design for easy installation, suitable for high-speed, high-frequency operations.  
   - Friction plates use modified phenolic resin and inorganic fiber composites, offering high-temperature resistance (≤350°C), stable friction coefficients, noiseless operation, and no damage to mating discs.  
2. Safety & Environmental Compliance  
   - Asbestos-free friction materials meet environmental standards.  
3. Easy Maintenance  
   - Friction plates can be replaced without disassembling the clutch body, enabling online maintenance.  
4. High Adaptability  
   - Customizable clutch ear plates to suit diverse installation requirements.  
 4. Technical Specifications  
 Parameter  Specification   
 Working air pressure  5.5~6.0 kg/cm²   
 Friction plate lifespan  ≥500,000 cycles (varies by usage)  
 Operating temperature  20ºC ~ +150ºC   
 Response time  ≤0.02 seconds (clutch/brake)   
 Spindle tolerance  Bore tolerance H7, spindle surface roughness Ra1.6   

 5.Installation and Commissioning  
 1. Installation Steps  
1. Spindle adaptation: Ensure spindle geometric tolerance and surface finish comply with standards (refer to national standards).  
2. Component assembly:  
   - Install clutch/brake plate pins and locking plates first, followed by the main body.  
   - Add a sealing cover for axial air intake.  
3. Flexibility test:  
   - Manually rotate the clutch plate before air supply to confirm smooth movement.  
 2. Commissioning Guidelines  
- Verify stable air pressure (≥5.5 kg/cm²) before startup.  
- Conduct no-load tests to check clutch/brake response times during initial operation.  
 6. Maintenance and Troubleshooting  
 1. Routine Maintenance  
- Regularly clean friction plates to remove oil contamination and prevent reduced friction.  
- Inspect spring tension and seal conditions quarterly.
 2. Friction Plate Replacement  
- Clutch plates: Replace directly by removing screws without air supply.  
- Brake plates: Release brake ear plates by supplying air before replacement.
 3. Common Faults and Solutions  
 Fault  Possible Cause  Solution   
 Clutch fails to engage  Low air pressure/solenoid valve failure  Increase pressure or replace valve   
 Poor engagement  Worn/contaminated friction plates  Replace plates or clean   
 Braking delay  Spring fatigue/air leakage  Replace spring or repair air circuit   
 7.Safety Precautions  
1. Pre-maintenance Actions  
   - Disconnect power and air supply, depressurize the system.  
   - Position the slider at the lower dead center to prevent accidental movement.  
2. Disassembly Rules  
   - Restrain brake spring force release to avoid injury.  
   - Replace damaged parts immediately; repairs are prohibited.
