I. Anti-Tearing Deep Drawing Technology
Mining trays often require deep deformation (doming). Our anchor rod tray mould utilizes a proprietary draw-bead design that controls material flow precisely, preventing the common "corner cracking" or thinning issues associated with low-quality tooling.
II. High-Impact Resistance Inserts
Stamping $8\text{ mm}$ or $10\text{ mm}$ steel plate creates immense shock loads. We use oversized, shock-resistant inserts and heavy-duty guide pillars to absorb vibration, protecting the die from fatigue-related cracking and ensuring a service life exceeding $500,000$ strokes.
III. Integrated Piercing & Forming
To maximize efficiency, our moulds can integrate the center hole piercing and the dome forming into a single stroke. This "combo-die" approach ensures that the bolt hole is perfectly concentric with the dome, which is critical for the balanced loading of the anchor rod.
IV. Stress-Relieved Design
All our large-scale mining tray dies undergo multiple tempering cycles to relieve internal stresses. This prevents the mould from warping over time, even when operating in unheated factory environments or under continuous high-speed cycles.
Workflow & QC
FEA Stress Analysis: We simulate the stamping process to identify high-stress zones before cutting steel.
CNC Precision Milling: Precise geometry for the dome and rib profiles to ensure the tray's structural integrity.
Manual Polishing: Critical forming surfaces are mirror-polished to reduce friction and improve the surface finish of the trays.
T1 Trial: Final testing on a high-tonnage hydraulic press with your specified material grade.
FAQ for Google
Q: Can your tray mould handle high-tensile mining steel like Q345 or Grade 500? A: Yes. We adjust the die clearances and upgrade the punch materials to DC53 or carbide-reinforced steel to handle the higher springback and hardness of high-tensile materials.
Q: What is the maintenance required for an anchor plate die? A: We recommend regular inspection of the drawing radius and periodic lubrication of the guide pillars. Our modular design allows you to sharpen or replace the piercing punch without disassembling the entire die set.
Q: Do you provide custom shapes for butterfly or specialized star plates? A: Absolutely. We can design custom geometry based on your specific geotechnical requirements or local mining safety standards.
