Integrated High-Efficiency Operation: This production line integrates fully automatic blanking and hot punching processes, enabling continuous production from raw material cutting to precise punching. This significantly reduces material handling between stages and shortens lead times.
High Precision and Consistency: Utilizing advanced positioning systems and a high-rigidity press structure, the blanking accuracy reaches ±0.2mm to ±1mm. High punching precision ensures exceptional part consistency to meet strict technical specifications.
Localized Precision Induction Heating: The punching section employs medium-frequency induction heating focused specifically on the hole area. This method features minimal heat conduction, precise temperature control (800-900℃), and significantly lower energy consumption than traditional equipment.
Maximization of Material Utilization: Through automated optimized nesting and blanking, the system automatically calculates the best cutting plans based on product specifications, maximizing raw material usage and reducing production costs.
Intelligent Control and Safety Protection: Equipped with a PLC control system and an HMI touchscreen, the line supports automatic feeding, unloading, and real-time monitoring. Integrated photoelectric sensors and emergency stop devices ensure operator safety during high-intensity continuous production.

Hot punching of leaf springs:
Features: Hot punching of leaf springs involves a small heating area, resulting in lower energy consumption compared to other equipment;
temperature is precisely controlled, preventing overheating;
heating efficiency is higher, with minimal heat transfer, allowing staff to handle the workpieces directly by hand.
The diameter range for hot punching depends primarily on a number of factors, including the capacity of the equipment used, the thickness and type of material, the die design, and the punching pressure. Typically, hot punching is used to produce holes with larger diameters, particularly in thicker or harder materials. Below are some common diameter ranges
