Based on the hot forging process, we aim to break through the traditional production bottlenecks.
The nut, as an important component of fasteners, is widely used in mechanical equipment, automotive manufacturing, engineering structures, and other fields. The current traditional production method of hot forged nuts mostly relies on manual operations for loading the raw materials and transporting the workpieces among various presses. This not only has low efficiency but also the product quality is easily affected by human factors, making it difficult to meet the requirements of modern manufacturing for stability and consistency.
LiteTech Technology conducted a thorough analysis of the manufacturing characteristics of hot forging nuts. In response to the batch production requirements for common specifications such as M18-M42 nuts, they designed and developed a modular automated forging production line. The overall layout of the line aims to enhance production continuity and reduce defect rates. Through intelligent coordination among equipment, the line achieves automated processing from raw materials to semi-finished products.
Integrated full-process procedures, establishing efficient production rhythm
The Laitai Technology nut automated forging production line is composed of multiple functional modules working together. Each link is seamlessly connected, forming a complete production loop:
Automatic feeding and sorting system: At the front end of the production line, an automatic unbolting device or a dump loader is equipped. It can handle bundled or loose bar materials and automatically complete unbolting, sorting, and directional transportation. The system uses sensors to monitor the feeding status in real time, ensuring a stable and continuous supply of raw materials and avoiding efficiency losses caused by manual handling and Bumps of the bars.

  Medium-frequency induction heating and temperature sorting: After the bar material enters the medium-frequency heating furnace, it is rapidly heated to the required temperature range for hot forging through electromagnetic induction. The equipment is equipped with an infrared temperature measurement closed-loop control system, which can adjust the heating power in real time to ensure the uniformity of the material temperature, providing a stable foundation for subsequent forging. The heated material then undergoes the temperature sorting process, where it automatically screens and rejects the materials with不合格 temperatures， ensuring the quality of the forgings from the very beginning.
   High-pressure descaling treatment: After heating, the surface of the billet will form an oxide layer. If not removed in time, it will affect the surface quality of the forging and aggravate the wear of the mold. Lintai Technology is equipped with a high-pressure water descaling system. Through high-speed water flow, the oxide layer on the surface of the billet can be effectively removed, restoring the cleanliness of the metal surface, improving the fluidity of the metal during forging, and at the same time extending the service life of the mold.
Multi-station automated forging: This is the core part of the entire production line. According to the forming requirements for different specifications of nuts, Lifan Technology offers two automated forging process solutions:
   Bilateral manipulator collaborative system: Equipped with high-precision servo robotic arms, it can perform tasks such as grasping, flipping, and transferring the billets among multiple forging equipment, enabling continuous and automated processing of processes like upsetting, pre-forging, final forging, and punching.

Stepping beam multi-station forging: For heavy-duty and oversized nuts such as M64, a stepping beam system is used to precisely control the movement of the blank between multiple forging stations. Combined with professional forging equipment, it enables step-by-step forming, ensuring the shape accuracy and internal structural stability of the heavy-duty nuts.

Automatic product transportation: The finished nut blanks that have undergone forging and punching are transferred to the finished product frame or subsequent processing steps through an automatic transportation chain. No manual transfer is required, which avoids damage to the finished products due to bumps, ensuring a complete closed-loop production process.
Intelligent control and quality traceability
The entire production line adopts a PLC control system integration, supporting centralized setting and real-time monitoring of parameters for each process. The equipment can reserve data acquisition interfaces to record process parameters at each stage, providing data support for enterprises to conduct quality traceability and process optimization in the future. In addition, the production line is equipped with multiple safety protection and abnormal alarm functions, including fault alarms, under-material alarms, etc., ensuring the safe and stable operation of the equipment even when operated by unmanned or with a reduced number of operators.
Flexible solution design and customization capabilities
In response to the production needs of different customers, Laitai Technology can provide customized layout schemes for various specifications of nut production lines. Currently, it has formed a series design capability covering M20-M33, M36-M42, and M64 heavy-duty nuts, and can adaptively renovate based on the existing equipment conditions and workshop layout of customers. Whether it is building an intelligent workshop or upgrading the existing production line with automation, Laitai Technology can provide one-stop services from solution planning, equipment manufacturing to installation and commissioning.
