The Automatic Flat Steel Hoop Making Machine is a CNC-controlled production solution designed for manufacturing U-clamps, flat steel hoops, pipe saddles and other formed flat-steel components.
It integrates automatic feeding, straightening, punching, bending, forming, cutting and unloading into one continuous production process. Compared with traditional manual or semi-automatic methods, the machine helps reduce labor requirements and improve production efficiency.
With CNC control and automated processing, the machine delivers consistent dimensions and stable production for high-volume manufacturing. It is suitable for fastener factories, metal fabrication workshops, pipe-support manufacturers and other industrial applications.
Machine Features
Automatic Flat Steel Hoop Making Machine
Traditional production of U‑clamps and flat steel hoops relies on separate machines for straightening, hole punching and bending. Multiple operators are required for material transferring, which brings unstable product quality, low output and high reject rate. This high‑speed U‑clamp forming equipment solves those pain points by highly integrating each processing station, only one operator is needed for whole‑line running, realizing continuous automated production of pipe clamps and hoops
Core Working Principle & Process Flow
The machine adopts servo feeding matched with hydraulic power system, controlled by PLC and touch‑screen HMI. Operators input parameters including strip width, thickness, hole position, bending radius and finished‑product length on the screen, and the equipment runs automatically as programmed
Complete workflow:
- Decoiling & feeding: Coiled flat steel is loaded onto the uncoiler, raw material is sent into the main unit steadily。
- Automatic straightening: Multi‑roller leveling mechanism eliminates material warpage to ensure flatness of incoming strips.
- Hydraulic punching: Precision hydraulic punch presses mounting holes on flat steel according to preset positions. Molds can be quickly changed for different hole sizes.
- Precision bending & forming: Mechanical bending module bends flat steel into U‑shape, semicircular or circular hoop profiles.
- Automatic cutting: Finished clamps are cut off to set length.
- Automatic unloading: Finished U‑clamp / flat steel hoop falls onto output table for collection。
Key Features
- Full‑process automation: One‑machine completion of feeding‑straightening‑punching‑bending‑cutting‑unloading. Only one worker is required for operation, labor cost is sharply reduced
- High‑speed & stable output: Production speed reaches 12‑25 pieces per minute, suitable for large‑batch continuous production. Forming tolerance can be controlled within ±0.5 mm, high consistency among workpieces。
- Flexible mold‑change design: Modular mold structure supports quick replacement. It can produce U‑clamps, pipe hoops, semicircular saddles and other special‑shape fasteners by swapping molds, meeting diversified customization demands
- Intelligent CNC control: Human‑machine touch screen with multi‑language option. Parameter modification is simple; no complex programming skill is required for operators. Real‑time fault alarm facilitates troubleshooting。
- Heavy‑duty durable structure: Main frame uses thick‑welded steel plate; core hydraulic and servo components adopt industrial‑grade parts, supporting long‑time 24‑hour non‑stop operation in harsh factory environments
- Wide material adaptability: Process carbon steel, galvanized flat iron, stainless‑steel strips, applicable for strip width 20‑100 mm, thickness 2‑8 mm (configurable by model)
