Front Subframe Mold Blank Positioning System & Anti-Shift Locating Design

Front subframe mold adopting combined pin + surface support positioning system restricts blank shifting, keeping blank positioning repeatability within ±0.2mm for automatic feeding.
Blank positioning consists of locating pins, blank support plates and pre-stop blocks. The positioning layout must match blank contour and material feeding path. Sufficient support prevents blank sagging before forming, which is critical for automated robotic loading.
Subframe stamping project data shows blank positioning deviation causes 39% of unstable forming defects, including wrinkling, cracking and inconsistent part contour position.
Local front subframe mold suppliers can optimize locating layout for robotic feeding, and provide 24-hour remote guidance for locating pin height adjustment and blank stop calibration.
The difference between simple two-point pin positioning and multi-point combined positioning system is clear. Two-point pin positioning is low cost for manual loading; multi-point positioning with blank support is required for high-speed robotic automatic feeding.
A common design pitfall is only using locating pins without enough blank support. Large thin blank sags under its own weight, leading to positioning offset before mold closing.
Optimized blank positioning and blank support structure increases front subframe mold cost by 6%–13%. This investment guarantees feeding repeatability and reduces forming instability.
Common positioning system faults include locating pin wear, support plate scratch, blank bounce and stop block deformation. Locating pin position and height inspection should be performed every 10,000 stamping cycles.
When comparing front subframe mold manufacturers, verify positioning simulation and blank feeding test result. Professional vendors cooperate with robot integrator to match feeding trajectory.
Blank positioning and anti-shift design for front subframe molds applies to robotic automatic feeding production line of high-strength steel and aluminum subframe blank.
