HVAC Duct Corner Cleat Punching Machine for TDF/TDC Flange Corners
High-Efficiency TDF/TDC Flange Corner Production: Engineered specifically for the continuous high-speed stamping and punching of rectangular HVAC duct corner cleats and flange codes (standard #30 and #40 sizes).
Precision Multi-Station Progressive Die: High-grade Cr12MoV vacuum-quenched stamping tooling integrates hole punching, stiffening rib grooving, and outline blanking into one reliable stroke without scrap clogging.
Overview & HVAC Duct Corner Fabrication
The HVAC Duct Corner Cleat Punching Machine is a high-speed mechanical stamping press purpose-built for mass-producing galvanized corner cleats (corner codes) used in rectangular HVAC ventilation ductwork. It provides essential structural rigid corners for standard TDF (transverse duct flange) and TDC flanged joint systems.
Driven by a high-inertia mechanical flywheel transmission and fitted with high-precision progressive stamping dies, this machine executes sheet feeding, precision screw-hole punching, deep stiffening rib embossing, and angle blanking in a rapid cycle, outputting uniform corner cleats ready for immediate job site assembly.
Precision Tooling & Mechanical Engineering
- Cr12MoV Progressive Stamping Dies: Multi-station progressive tool sets crafted from vacuum-quenched Cr12MoV tool steel guarantee sharp cutting edges, dimensional accuracy, and long tooling life exceeding hundreds of thousands of cycles.
- Rigid Cast Frame Structure: Heavy-duty one-piece cast body absorbs mechanical impacts and provides superior dampening, preventing die misalignment during continuous high-tonnage stamping.
- Dual Pushbutton Safety System: Integrated two-hand concurrent pushbuttons prevent accidental strokes and keep operator hands safely away from the die area during operation.
- Versatile Interchangeability: Easily switchable die sets accommodate standard #30, #35, and #40 corner cleat profiles as well as customized duct fittings.
