Product Description
Howann Model 60-6 CNC Flat Iron Hoop Forming Machine | Automatic Pipe Clamp & Bracket Making Machine
The Howann Model 60-6 is a medium-duty, fully automatic CNC flat bar forming machine engineered for the high-volume production of pipe clamps, pole hoops, saddle brackets, and custom flat metal fittings.
By seamlessly integrating strip straightening, servo feeding, hydraulic punching, CNC bending, and fixed-length shearing into one uninterrupted workflow, it entirely eliminates manual material handling between processes. This guarantees unmatched dimensional accuracy across large batches while operating at peak efficiency.
Core Advantages
- Die-Free Quick Changeover: Switch between different clamp widths, lengths, and hole patterns instantly via the touchscreen. No physical die replacement is needed, virtually eliminating production downtime.
- Single-Operator Workflow: One worker easily manages coil loading, monitoring, and part collection. Drastically cut your workshop staffing requirements and labor costs.
- High-Speed Volume Production: Delivers a maximum feeding speed of 55 m/min and a 180°/sec bending speed, ensuring rapid cycle times for bulk orders.
- Dual-Servo Precision Control: Powered by a 4.5 kW feeding servo and a 4.5 kW bending servo. Closed-loop control ensures dead-on hole positioning and uniform bending angles every single time.
- Industrial-Grade Durability: Feed rollers and forming dies are crafted from DC53 tool steel with 61° hardening treatment. Combined with premium Rexroth/Huade hydraulics, it guarantees long-term precision and low maintenance.

Machine Structure & Working Principle
1. Straightening & Servo Feeding Unit
Multi-roller straightening mechanism removes coil curvature and flatness defects from raw flat bar. The 4.5 kW servo-driven feeding system delivers fixed-length material to each processing station with high positioning accuracy. Feed rollers are made of hardened DC53 steel for superior wear resistance and long service life.
2. Hydraulic Punching Station
Two 125×50 reinforced force-amplifier hydraulic cylinders perform hole punching, slotting and marking operations. The stable hydraulic system delivers clean, burr-free holes and notches across the full thickness range of the machine.
3. CNC Bending Forming Unit
The 4.5 kW servo-controlled bending head forms flat bar into various profiles including circular hoops, U-clamps, saddle brackets and custom shapes. 180°/sec bending speed ensures fast cycle times while maintaining consistent angle accuracy.
4. Fixed-Length Shearing Unit
The 150×50 reinforced shear cylinder cuts finished parts to exact target length with clean, even edges, eliminating the need for secondary deburring for most standard applications.
5. Intelligent CNC Control Cabinet
Touchscreen control panel with intuitive interface stores multiple production recipes for instant recall. Supports parameter adjustment for different part sizes, production counting and fault self-diagnosis, easy to operate with minimal operator training.
Finished Products & Applications
This machine produces a wide range of flat bar formed fittings for multiple industries:
- Power Utility Fittings: Pole hoops, cross-arm clamps, cable brackets.
- Pipeline Accessories: Pipe saddle clamps, U-brackets, pipe hangers.
- Municipal Hardware: Street light pole brackets, signpost hoops.
- Custom Metal Forming: Tailored punching & bending profiles.
Customization Options
- Global Voltage Adaptation: 220V, 380V, 415V, 440V (3-phase, 50/60Hz).
- Custom Tooling & Stations: Special punch patterns, additional marking, or chamfering stations based on your drawings.
- OEM Branding: Custom machine colors, logo placement, and reinforced export packaging.
Frequently Asked Questions
Q: What materials can the Model 60-6 process?
A: It is designed for flat iron, carbon steel strip, galvanized steel, copper bar and aluminum bar within the 20-60mm width and 2-6mm thickness range.
Q: How long does it take to switch production to a different clamp size?
A: For standard size changes within the machine's rated range, operators only need to adjust parameters on the touchscreen or select a saved recipe. The full changeover takes only a few minutes, no die replacement required.
Q: What level of operator skill is required to run this machine?
A: The control interface is designed for intuitive operation. Workers with basic mechanical knowledge can master full production operation after 1-2 days of training. No specialized programming skills are needed.
