Equipment Core Introduction:
The Fully automatic Diamond shaped lock mouth tube forming machine is a specialized automation equipment designed for continuous cold bending of diamond shaped lock mouth structures at the end of metal pipes. Through multiple sets of precision rollers and servo hydraulic cooperation, it can process standard diamond shaped bite lock mouths for round pipes, square pipes, and special-shaped pipes at once, achieving rapid pipe docking, sealing locking, and structural enhancement. It is widely used in fields such as air ducts, water supply and drainage, municipal pipe galleries, mechanical structures, and prefabricated buildings, and is the core equipment for deep processing and system assembly of pipes.
The whole machine consists of six major systems: unwinding leveling, automatic feeding, multi pass roll forming, servo positioning, cutting/closing, electric control and hydraulic. It adopts continuous roll forming technology, which does not require heating, welding or waste, and the forming process is stable and controllable. The equipment is compatible with commonly used pipes such as galvanized steel pipes, stainless steel pipes, carbon steel pipes, aluminum alloy pipes, etc. The processing diameter and wall thickness can be customized according to specifications. After forming, the locking size is uniform, the bite is tight, and the mechanical properties are stable, meeting the requirements of batch standardized production.
Typical application scenarios
• HVAC duct system
Used for forming rectangular/circular duct locks, with tight bite and low air leakage rate, suitable for central air conditioning and ventilation projects such as shopping malls, office buildings, factories, hospitals, etc., to improve the efficiency and airtightness of duct installation.
• Municipal water supply and drainage and pipe gallery engineering
Processing pipeline connection locking ports to achieve fast socket locking, reduce flange and welding, improve pipeline sealing and anti settlement ability, suitable for urban pipeline networks, comprehensive pipe galleries, and rainwater and sewage diversion projects.
• Prefabricated buildings and steel structures
Used for structural locking of columns, beams, and support pipes, enhancing node strength and assembly accuracy, shortening on-site construction period, and adapting to modular buildings, light steel villas, and steel structure factories.

Core technical features
1.High molding accuracy and good consistency
Multi pass rollers are formed step by step, with precise and controllable locking angle, depth, and bite clearance. There are no ellipses, scratches, or burrs, and the sealing and locking effects are stable after assembly, greatly reducing the risks of air leakage, water leakage, and loosening.
2.High degree of automation and outstanding production efficiency
Supporting automatic feeding, automatic forming, and automatic fixed length cutting, the single shift production capacity can reach thousands of units, which is several times more efficient than manual/semi mechanical processing and suitable for large-scale assembly line operations.
3.Strong material adaptability and stable process
Compatible with conventional wall thicknesses of 0.4-1.5mm, it can quickly switch pipe diameters and lock specifications, making mold changes convenient and debugging simple; Cold forming does not damage the material coating and mechanical properties, resulting in better corrosion resistance and strength of the finished product.
4.Durable structure and low maintenance cost
Thick plate welding and aging treatment of the frame result in low operating vibration and long service life; Wear resistant design of key components, automatic lubrication and overload protection, reducing downtime and consumption of vulnerable parts.
5.Safe, reliable, and user-friendly to operate
Fully enclosed protection, emergency stop, misoperation protection, Chinese visual interface for beginners to quickly get started; Supports manual/automatic/single step mode, meeting the dual requirements of debugging and production.
