Hot Forging Process
Material Feeding: Servo-driven pinch-roll feed system typically meters bar stock with length tolerances within ±0.5 mm to help minimize flash waste.
Induction Heating: Multi-stage medium-frequency furnace generally heats billets up to 1150°C, supported by closed-loop pyrometer control and scale removal options.
Hot Forging: Heavy-duty press is designed for multi-station operations (such as upsetting, extrusion, and piercing) with a rigid frame to help reduce structural deflection.
Automatic Transfer: Multi-axis servo manipulator can be electronically synchronized with the press crank angle to facilitate smooth workpiece transfer.
Forming & Ejection: Progressively shapes components toward net-shape geometries utilizing mechanical ejection mechanisms to route parts to discharge conveyors.
Machine Configuration
Feeding System
Servo-driven hardened rollers handling bar stock up to 100mm with pneumatic clamping.
Induction Heating Furnace
Solid-state IGBT inverters with quick-disconnect cooling and dual infrared sensors for thermal monitoring.
Forging Press
Stress-relieved steel frame with centralized lubrication and pneumatic clutch-brake assemblies.
Automatic Manipulator
Alloy gripper arms with independent servo axes, programmable travel, and torque limits.
Die & Tooling System
Hot-work tool steel (e.g., H13) inserts with thermal coatings and quick-change cassettes.
Control System
Industrial PLC with a touchscreen HMI, safety interlocks, error diagnostics, and recipe storage.
Applications
Nuts
Hex nuts, heavy hex nuts, flange nuts, lock nuts and other forged nut blanks.
Bolts & Fasteners
Hot-formed bolt heads and other large-size or high-volume fastener components.
Washers
Hot-forged washers and ring-shaped parts requiring upsetting and piercing.
Bearing Rings
Ring blanks produced by hot upsetting and piercing operations.
Special Forged Parts
Custom-shaped components according to product drawing, material and forging requirements.
Customization
Plant Layout & Infrastructure: Tailor equipment footprints, load distribution (2000kg–3700kg), input voltages, and cooling interfaces to your facility.
Tooling, Stroke & Clamping: Modify clamping diameters (55mm–100mm), heights (50mm–80mm), strokes (170mm–300mm), and table dimensions for non-standard fasteners.
Material & Thermal Parameters: Configure induction heating frequencies and thermal curves for high-alloy or stainless steel up to 1000°C.
Engineering Workflow: Submit drawings and constraints for direct senior engineering review, specification sign-off, and custom manufacturing.
Quality Testing
Raw Material Verification: Ultrasonic and metallurgical testing of incoming high-alloy stock to ensure material integrity prior to thermal processing.
Thermal & Sensor Calibration: Rigorous thermal profiling of induction heating zones (up to 1000°C) and calibration of closed-loop servo sensors to maintain precise temperature and speed regulation.
Dimensional & Tolerance Inspection: Post-forging verification of clamping dimensions, stroke accuracy, and structural geometry against international fastener standards.
Full-Line Factory Run-off: Comprehensive load testing and synchronization trials of the integrated feeder, furnace, press, and manipulator prior to shipment.
Installation & After-Sales
On-Site Commissioning: Factory-certified engineers provide direct on-site installation, machine leveling, and initial operational calibration.
Technical Training: Comprehensive on-site training for your operators and maintenance team covering PLC programming, routine maintenance, and safety protocols.
Remote Diagnostic Assistance: Dedicated technical support team available for remote troubleshooting, operational guidance, and firmware updates.
Spare Parts Availability: Dedicated inventory channels ensuring rapid dispatch of replacement mechanical and electrical components to minimize downtime.
