product description

This round pipe to square tube cold roll forming machine, uniformly named Square Tube Forming Machine From Round Pipe Cold Roll Forming Machine, is a specialized metal cold forming equipment designed to directly convert round steel pipes into square and rectangular tubes through multi-pass continuous rolling deformation. It is widely applied in metal processing factories, construction steel manufacturing, greenhouse frame production, guardrail pipe processing and other industries, delivering high efficiency, stable molding and low production cost for secondary pipe forming.

Equipped with standard CE and SGS certification, the whole machine meets international quality and safety standards, fully suitable for global export sales to Europe, Southeast Asia, Middle East and other overseas markets.

Main Machine Structure

1. Power Driving System High-power copper core motor provides stable and sufficient driving force, matched with reliable transmission structure to ensure uniform rolling speed, avoid pipe slipping and deformation during molding. The motor runs with low noise, long service life and low failure rate for long-time continuous production.
2. Multi-Stage Forming Roller Groups Multiple groups of high-precision alloy steel forming rollers are arranged in progressive order. Each roller undergoes precise CNC machining and surface hardening treatment, with high wear resistance and smooth forming surface. The round pipe is gradually extruded and shaped from circular to square shape step by step through each roller station, effectively preventing pipe cracking, surface scratches and uneven wall thickness. Adjustable red positioning fixtures are installed on each roller station, allowing fast adjustment of pipe specifications (square tube side length, wall thickness) to realize multi-size production on one machine.
3. Integrated Welding Machine Frame The whole base adopts thickened steel plate integral welding structure, with high rigidity and strong shock resistance. It will not generate frame vibration or deformation during long-term high-speed rolling, guaranteeing consistent dimensional accuracy of finished square tubes. Hollow design at the bottom reduces overall weight while maintaining structural stability, convenient for handling and installation.
4. Quick Adjustment Assembly All roller stations are equipped with screw adjusting hand wheels and positioning locking devices. Operators can rapidly switch processing specifications without complex disassembly, greatly shortening model change time and improving overall production efficiency.

Core Advantages

1. One-step Molding Process Directly process raw round pipes into finished square tubes, canceling intermediate cutting and reprocessing links, save raw material waste and labor cost, and shorten production flow.
2. High Precision Forming Effect Multi-pass gradual rolling avoids forced one-time deformation, finished square tube features neat edges, smooth surface, uniform wall thickness and standard right-angle radian, which can directly meet welding, spraying and finished product assembly requirements without secondary polishing.
3. Wide Processing Range Supports processing various metal pipes: galvanized round pipe, black iron round pipe, stainless steel round pipe, etc. Adjustable forming stations cover multiple square tube sizes to meet diversified production demands of different customers.
4. Durable & Low Maintenance All forming rollers adopt wear-resistant alloy material with long service cycle; the transmission part is equipped with lubrication structure, daily maintenance is simple, spare parts replacement cost is low.
5. International Standard Certification Comes with CE safety certification and SGS product quality certification, complies with EU mechanical safety standards, smooth customs clearance for overseas buyers, reliable quality guarantee for global distributors and processing factories.
