As global automotive OEMs accelerate their lightweighting initiatives, Advanced High-Strength Steel (AHSS) has transitioned from an alternative material to the dominant standard for safety-critical structural components. Cross beams, A/B pillars, anti-collision beams, and side-impact reinforcements are now routinely manufactured from material grades ranging from 800MPa dual-phase (DP) steel to 1500MPa press-hardened steel (PHS / 22MnB5). While these materials deliver exceptional strength-to-weight ratios, they introduce a manufacturing challenge that many stampers underestimate: AHSS coils retain significant internal stresses from the cold rolling and annealing processes, manifesting as edge waves, center buckles, longitudinal curl, and cross-bow. When these defects enter a stamping die without proper correction, they amplify under forming pressure, producing dimensional deviations of several millimeters, unacceptable surface quality, and in severe cases, complete part rejection. The Yuanjia 300-1300HSS Precision Leveling Machine is specifically engineered to address the AHSS flatness challenge. It achieves flatness control of ≤0.1mm per square meter and handles yield strengths up to 1500 MPa — covering the full range of AHSS and ultra-high-strength steel (UHSS) grades used in modern automotive platforms. The machine’s 21-roller three-stage precision straightening system is the technological heart of the solution. The process is divided into three functional zones: the front section employs

A typical automotive cross beam production line spans 50 to 60 meters, integrating decoiling, straightening, feeding, stamping, and roll-forming operations. In such extended-process layouts, the most devastating efficiency killer is rarely the cycle time of any individual machine — it is the coil change downtime. Conventional single-head uncoilers require operators to stop the entire line, thread out the remaining tail, hoist a new coil, clamp and expand it, feed the leading edge through the straightener, and re-establish tension before production can resume. This entire sequence consumes 15 to 30 minutes even for experienced operators. With 4 to 6 coil changes per day on a busy cross beam line, the cumulative non-production time reaches 1 to 3 hours every single day — a silent but substantial drain on capacity and revenue. The Yuanjia KHT Series Double-Head Uncoiler is purpose-built to eliminate this bottleneck entirely. Its core design philosophy centers on dual-station alternating feeding with zero-downtime coil switching. Each station features an independently driven spindle powered by a Siemens variable-frequency motor with a dedicated inverter. A hydraulic expansion mechanism accommodates coil inner diameters from 460mm to 530mm, with a maximum outer diameter of 1600mm. While one station is actively feeding material into

Roll rolling production lines are widely used in the manufacturing of automotive crossbeams, anti-collision beams, and logistics shelves. These production lines consist of multiple pieces of equipment such as uncoilers, levelers, feeders, punch presses, rolling mills, and shears. As a result, the production lines are extremely long, ranging from 20-30 meters in the short case to 50-60 meters in the long case.​Trying to bring a coil head to the end of the production line is an extremely labor-intensive task. At this point, we can choose the automatic butt welding machine we produce. We usually place it between the leveler and the feeder. It can automatically weld the heads and tails of two coils of materials together, thereby significantly reducing the manual material threading time, improving production efficiency, and greatly enhancing production safety.​For enterprises engaged in the production of automotive crossbeams, anti-collision beams, and logistics shelves, the length of the roll rolling production line has always been a challenge in the production process. The manual material threading work not only consumes a lot of labor but also affects the continuity of production. The emergence of the automatic butt welding machine has effectively solved this problem.​By automatically connecting the material heads and
