Operating Principle of Valve Blank Forming Equipment

Valve Blank Forming Equipment is a specialized machine used specifically for manufacturing engine valve blanks. Its core operating principles include:

Hot Forging System: Utilizes medium-frequency induction heating (1000-1200°C) in conjunction with a multi-station press (400-1200 tons) to achieve precision forging of metal bars.

Precision Die Forging Process: Through the closed extrusion of upper and lower dies, hot metal flows and forms within the die cavity, completing the integral forging of the valve head and stem in a single forging operation.

Automated Control: A PLC system coordinates parameters such as heating temperature, forging pressure, and feeding rhythm to ensure forming accuracy and process stability.

 

Features of Valve Blank Forming Equipment

High Material Utilization: The near-net-shape forming process achieves a material utilization rate exceeding 85%, reducing machining allowances.

Excellent Microstructure and Properties: The forged metal has continuous and complete flow lines, and the mechanical properties of the product are 20-30% higher than those produced by cutting.

High Production Efficiency: Automated production lines can reach 80-120 pieces/minute, suitable for large-scale production.

High dimensional accuracy: Forming tolerances are controlled within ±0.2mm, ensuring uniform subsequent machining allowances.

Long mold life: Using H13 hot-work die steel and equipped with an intelligent lubrication system, the mold life exceeds 50,000 pieces.

 

Operating Specifications for Valve Blank Forming Equipment

Pre-production Preparation

Check mold installation and cooling system

Confirm bar diameter and heating temperature parameters

Perform a no-load test run to test the operation of each mechanism.

 

Production Process Control

Monitor heating temperature fluctuations (within ±20°C)

Regularly inspect blank dimensions and surface quality

Promptly clean any oxide scale residue from the mold surface.

 

Safety Precautions

Die adjustments are strictly prohibited while the equipment is running. Specialized tools must be used to remove and place hot blanks. The emergency stop device must remain active.

 

Typical Applications of Valve Blank Forming Equipment

Automotive Engines: Gasoline/Diesel Engine Intake and Exhaust Valves

Motorcycle Engines: High-Speed, Small-Displacement Engine Valves

Marine Power: Large Diesel Engine Valve Blank Manufacturing

Specialty Engines: High-Temperature-Resistant Valves for Natural Gas Engines
