STD Servo Series H‑Frame Servo Press Boosts Heavy‑Duty High‑Strength Steel Stamping Performance

A professional automotive structural parts manufacturer in Guangdong upgraded its production line by introducing Dongguan Qiaosen STD Servo Series H‑Frame Single Crank servo punch presses, solving critical challenges of heavy‑load deformation, unstable precision and high scrap rate when stamping thick high‑strength steel. The customer mainly produces chassis reinforcement parts from 2.0–5.0mm AHSS high‑tensile steel with strict tolerance of ±0.01mm, previously using ordinary H‑frame mechanical presses with obvious frame deflection under heavy load.

STD‑250sv servo press features an integrated heavy‑duty H‑frame structure, four high‑strength tie rods and direct servo drive. Core technical indicators under 110% nominal load: frame deflection ≤0.022mm/m, repeat positioning accuracy ≤±0.003mm, slider parallelism ≤0.015mm/300mm, full‑load stamping speed 50–60 SPM and energy consumption only 0.70kWh/h. Equipped with 9 programmable motion curves, it realizes slow deep‑drawing forming to avoid high‑strength steel cracking.
