round pipe/tube making machine

Product Introduction

This roll forming machine is specially engineered to produce bamboo‑imitation perforated round steel tubes, widely used for garden fences, landscape railings, decorative enclosures, and architectural ornament projects. The whole production line integrates uncoiling, continuous roll forming, perforating, sizing, automatic cutting and output, realizing fully‑automatic one‑step forming from raw steel strip to finished imitation‑bamboo round tubes.

Core Technical Features

1. In‑line Integrated Roll‑Forming & Precision Perforation Multi‑station progressive cold roll forming achieves circular tube closure, while synchronized inline punching units create uniform perforations and simulated bamboo‑node textures in a single pass. This integrated process removes the need for separate stamping operations, minimizes material handling, and guarantees repeatable profile geometry and hole positioning across production batches.
2. Non‑stop Flying‑Saw Cutting System Equipped with high‑speed flying saw cutting module, performing flying cut‑to‑length without line deceleration or production halt. It delivers burr‑minimized, square tube end faces with tight length tolerance, avoiding dimensional deviation caused by start‑stop cycling for high‑volume continuous runs. Linear guide motion ensures cutting stability and long‑term service life.
3. Heavy‑Duty Rigid Machine Structure The main base adopts thick steel plate integral welding and stress‑relieved annealing treatment. High‑alloy forming rollers undergo precision CNC machining and surface hardening treatment. Robust frame construction suppresses vibration during long‑term high‑speed operation, improving profile accuracy and extending equipment service lifecycle.
4. Industrial PLC & HMI Automated Control System Full‑line centralized control via industrial PLC coupled with touch‑screen HMI. Operators configure tube diameter, wall thickness, hole pitch, cutting length and line speed on‑screen. Real‑time status monitoring, fault alarm and recipe storage functions enable rapid specification changeover, lowering reliance on skilled operators.
5. Broad Material & Specification Compatibility Compatible with galvanized steel, pre‑painted steel, carbon steel strips. Supports custom‑configured roller tooling for multiple tube outer diameters, wall thickness variants, diverse hole layouts and simulated bamboo joint profiles. Tooling sets can be exchanged to adapt to varied project specification requirements.

Production Workflow

Detailed description

1.Decoiler:Used to stand the steel coil and uncoil, keep them working stably. Manual and automatic options available

2.Punching device:Hydraulic punching,customized according to product punching requirements
