3-roller plate bending machine WyRoll 3R series

electrichydraulicfor tank manufacturing

Overview
The WyRoll 3R series provides industrial three-roll plate rolling for fast forming of cylindrical, conical and curved workpieces. The machine features hydraulic upper roll adjustment, electric side roll tilting and variable hydraulic drive. Suitable for medium-thickness plate processing (model dependent, up to 30 mm steel). Repeatability ±0.1 mm (model dependent).

Design & Core Features

• Symmetric 3-roll design for stable forming and predictable material flow.
• Hydraulic upper roll adjustment for precise stroke and clamping control.
• Electric side roll tilting (0–45°) to produce cones and variable-radius parts.
• Variable-displacement hydraulic drive with stepless speed regulation, pressure compensation and integrated oil cooling.
• Roll shafts machined from 42CrMo alloy steel, quenched and tempered, hard chrome-plated surface for extended service life.
• Advanced CNC control (touch screen) with 3D forming simulation, automatic roll positioning and recipe storage (up to 500 programs); multi-language support and remote diagnostics.

Machine Accessories (selected items)

• Required: High-Strength Roll Shafts — forged 42CrMo alloy shafts, quenched and tempered; hard chrome plating; suitable for carbon steel, stainless steel and aluminum plates.
• Required: Variable Displacement Hydraulic Drive — standard hydraulic power unit with energy-saving design (approx. 25% power saving), low-noise operation (≤72 dB) and integrated oil cooling.
• Required: CNC Control System — 3D simulation, automatic positioning and recipe management; touch-screen HMI and real-time parameter monitoring.
• Optional: CNC Side Support System — adjustable side supports to prevent plate deflection on wide plates (≥2500 mm) with hydraulic support rollers and position feedback.
• Optional: Industrial Chiller — PID-controlled cooling for continuous bending, anti-corrosion radiator and alarms for flow/over-temperature.
• Optional: Automatic Feeding & Centering System — programmable feeding with laser centering; positioning accuracy ±0.5 mm, feeding speed 0–12 m/min and integrated safety light curtain.

Applications & Performance
Designed for efficient forming of cylindrical, conical and curved components for pressure vessels, construction and shipbuilding. Models cover plate thicknesses and widths up to 30 mm and 4000 mm respectively (model dependent). Positioning accuracy and repeatability ensure consistent part geometry in production environments.

Support & Lifecycle Services

• On-site roll bending training: operator and maintenance training including programming and troubleshooting.
• Foundation engineering: custom foundation design and installation guidance for heavy-duty models.
• Roller maintenance service: roller surface reconditioning, hardness testing and anti-slip treatments by metallurgical engineers.
• 24-month warranty: coverage for drive rollers and CNC systems for two years under normal industrial use.
