The mechanical end flattening production line is designed for the end-forming of round bar or tubular workpieces such as springs and stabilizer bars, combining induction heating with mechanical pressing to transform the round cross-section at each end into a flat profile, meeting the precise geometric requirements of downstream operations such as eye-coiling, punching, and assembly.
The end-heating unit employs medium-frequency induction technology for fast, targeted localized heating of the workpiece ends, rapidly softening the end material to the optimal forming temperature within a tightly controlled zone. Heat is concentrated exclusively at the target area, leaving the rest of the workpiece thermally unaffected and preserving its overall mechanical integrity.
The mechanical pressing mechanism consists of high-rigidity tooling driven by hydraulic or mechanical actuation, applying stable and controlled forming pressure to the heated end in a single press stroke. The resulting flat ends exhibit high dimensional accuracy, consistent geometry, and strong repeatability — well-suited to high-volume continuous production.
The line integrates workpiece transfer, heating, and pressing in a seamlessly automated sequence with stable cycle times. The forming action is completed rapidly while the workpiece is still at temperature, minimizing heat loss effects on forming quality and ensuring that the flattened thickness and width at each end consistently meet process specifications.
The equipment features a compact footprint, robust structure, and straightforward maintenance, with no high-pressure or open-flame heating required — resulting in a safe and clean working environment. Tooling can be changed quickly to accommodate different diameters and wall thicknesses, enabling flexible multi-product production changeovers.
