Nut Types
Standard Hex Nuts: Forging of M12–M36 metric and imperial hex nuts conforming to DIN 934, ISO 4032, and ASME B18.2.2 specifications.
Flange & Automotive Nuts: Forming of integral flange, wheel, and locknut blanks for automotive chassis, suspension, and axle assemblies.
Heavy-Duty Structural Locknuts: Processing of Grade 8.8, 10.9, and 12.9 alloy steel raw stock into thick-walled fasteners for mining, structural steel, and railways.
Custom Forged Components: Multi-station forming of non-standard, asymmetric, and stepped industrial hardware engineered to customer engineering drawings.
Hot Forging Process
Induction Heating & Feeding: Mid-frequency induction units maintain the billet temperature within ±15°C before it is mechanically transferred to the first die.
Multi-Station Upsetting: Progressive pre-forming and body-forming dies redistribute the raw stock volume to prevent surface folds and material cracking.
Piercing & Chamfering: An integrated mechanical punch station creates clean center bores and outer-edge chamfers in a single press stroke.
Automated Station Transfer: Cam-driven transfer fingers move workpieces between dies at throughput speeds of up to 120 pieces per minute.
Installation Requirements
Foundation: Concrete pad with damping mounts designed to isolate operational kinetic impacts from surrounding plant infrastructure.
Electrical Supply: 380V/415V, 50/60Hz, 3-phase connection with built-in voltage stabilization for the induction heater.
Pneumatic & Cooling Utilities: Operational line pressure of 0.6–0.8 MPa compressed air paired with a closed-loop water system delivering a constant 15–20°C flow.
Lubrication & Scale Flushing: Centralized automatic oil lubrication coupled with high-pressure fluid channels under the bed.
Delivery & After-Sales Support
Factory Acceptance Test (FAT): Includes a continuous 100-piece production run using customer-specified steel grades and CAD drawings before packing.
On-Site Commissioning: Field technician deployment for foundation leveling, tooling alignment, electrical integration, and operator machine training.
Consumable & Wear Parts Stock: Standard punches, dies, and transfer fingers maintained in regional hubs for dispatch.
Warranty: 12-month structural warranty covering the main crankshaft and flywheel assembly, backed by Ethernet PLC remote diagnostics.
FAQ
Q: What nut size range achieves the maximum 120 pieces per minute?
A: The 120 PPM peak throughput is achieved on smaller M12-M20 standard hex nuts; larger flange nuts and heavy-duty locknuts above M24 typically run at 70-90 PPM due to increased material mass per stroke.
Q: What happens to the crankshaft and flywheel warranty if the equipment is used beyond standard three-shift operation?
A: The 12-month structural warranty remains valid under standard three-shift usage; continuous 24/7 operation beyond this profile requires prior notification to maintain full warranty coverage.
Q: Can we specify our own steel grade and design drawings for the Factory Acceptance Test?
A: Yes, the FAT includes a continuous 100-piece production run using your specified steel grade and CAD drawings, ensuring the equipment is ready before shipment.
Q: What voltage and utility conditions must our facility meet?
A: Your facility needs a 380V/415V 50/60Hz three-phase electrical supply, 0.6-0.8 MPa compressed air, and a closed-loop water cooling system maintaining 15-20°C flow.
Q: What information is required to select the correct nut former equipment?
A: The key selection data includes nut dimensions, blank weight, forging material, required production rate, press capacity, number of forging stations, and existing press configuration.
