The Role and Advantages of Automatic Graphite Spraying Devices in Precision Die Forging

Technical Principles and Functions of Automatic Graphite Spraying Devices

In precision die forging production, mold sticking is a critical issue that affects production line efficiency and stability. It not only leads to a decline in forging quality but also, especially under high-speed cycles, causes a sharp rise in mold temperature, triggering surface annealing of the mold, reducing its hardness, and significantly shortening its service life. Graphite emulsion, as an efficient lubricating and cooling medium, effectively improves metal flow, reduces friction, aids in demolding, and delays thermal fatigue through its cooling effect on the mold, thereby enhancing the surface quality of forgings and extending the mold's service life .

Traditional manual spraying methods not only require highly skilled operators but also necessitate performing spraying tasks while operating the equipment, resulting in low efficiency, poor consistency, and potential local lubrication failure or graphite waste due to uneven application. Furthermore, the dusty environment from manual spraying can impact worker health and equipment stability over the long term . The introduction of automatic graphite spraying devices aims to fundamentally resolve these issues, achieving precise, efficient, and safe mold protection .

Four Core Advantages of AYANK FORGING Automatic Graphite Spraying Device

The AYANK FORGING Automatic Graphite Spraying Device operates automatically based on pneumatic principles and a PLC control system. It ensures uniform, quantitative graphite lubrication for the mold in each forging cycle through automated positioning and spraying by nozzles between the upper and lower mold cavities . Its core advantages are as follows:

Negative Pressure Feeding: Combining Safety and Continuity

• Safer Design: Utilizes diaphragm pump negative pressure extraction instead of traditional pressure tank feeding, fundamentally avoiding the risks of leakage or even explosion associated with high pressure in tanks. This is particularly suitable for safe use near high-temperature forging environments .
• Non-stop Addition: Enables the addition of release agent during production without stopping the machine, ensuring continuity in forging operations and production efficiency .

Automatic Cleaning Function: Effectively Prevents Clogs and Reduces Maintenance

• Solves Residue Challenges: Addresses the issue of graphite-water mixture easily drying and hardening in pipelines and pump bodies with a built-in self-cleaning program. This program automatically flushes the pump and pipelines with tap water at the end of each workday.
• Extends Equipment Life: Effectively removes residual graphite, preventing blockages and wear, ensuring long-term smooth operation of the pump and pipelines, and reducing downtime caused by maintenance.

Quick Installation and Integration: Reducing Deployment Costs

• Simplified Interface Requirements: The compact device requires only one compressed air pipeline and one 220V power connection to operate .
• Convenient Automation Integration: Full automation is achieved by connecting two I/O output points from the main forging equipment's PLC to the device's electrical cabinet. Supports remote video-guided installation, reducing the need for on-site debugging personnel and accelerating commissioning.

Modular Structural Design: Flexible Adaptation to Multiple Scenarios

• Optional Spraying Methods: Offers fixed and telescopic spraying mechanisms based on mold structure and workstation requirements. Fixed types suit regular mold cavities, while telescopic types cover deep cavities or complex structures, ensuring complete coverage without dead angles .
• Adapts to Diverse Processes: Supports different nozzle configurations and flow adjustments, allowing flexible adaptation to various forging products (e.g., long shaft types, multi-cavity parts) and forging processes (e.g., hot die forging, precision forging) for lubrication and cooling needs .
