Hydraulic end flattening production line is engineered for precision end-forming of round bar or tubular workpieces such as springs and stabilizer bars, using a hydraulic drive system as the core actuating force. Working in conjunction with induction heating, it presses the round cross-section at each end into a flat profile to the tight geometric tolerances required by downstream eye-coiling, punching, and assembly operations.
The end-heating unit employs medium-frequency induction technology for fast, precisely targeted localized heating of the workpiece ends. Temperature is accurately set and controlled, ensuring the end material is fully softened to the optimal forming range while strictly confining the heat-affected zone to the end section, fully preserving the mechanical properties of the workpiece body.
The hydraulic drive delivers smooth, continuous, high-tonnage forming pressure. Compared to mechanical actuation, hydraulic output is more consistent and stroke position is more precisely controllable, enabling the line to handle larger cross-sections and higher-strength materials with ease. Pressure parameters can be readily adjusted to accommodate different workpiece specifications, supporting fast and flexible changeovers.
The close coordination between tooling and hydraulic cylinders ensures gradual and evenly distributed pressure application throughout the forming stroke, effectively eliminating the risk of end cracking or surface damage from impact forces. The resulting flat ends exhibit high dimensional consistency and excellent surface quality — well-suited to components with elevated precision and surface finish requirements.
The line integrates induction heating, workpiece transfer, and hydraulic pressing in a fully automated and synchronized sequence with stable cycle times. The absence of open flames or high-voltage hazards makes for a safe and clean production environment. The compact, low-maintenance equipment configuration supports continuous, high-volume, multi-product production.
