Automatic Alignment & No Manual Adjustment: Adopts integral self-aligning structure. The rollers can automatically adapt to different cylinder diameters, realizing one-click positioning without repeated manual calibration, which greatly improves working efficiency.
Stable Variable Speed Operation: Configured with advanced frequency conversion motor and VFD controller. The rotating speed is adjustable steplessly with smooth start and stop, no impact on workpieces, which perfectly protects the welding quality.
Heavy-Duty & Durable Structure: The main frame is made of thickened steel plate through integral welding and stress relief treatment. The wear-resistant rubber rollers have strong bearing capacity, anti-slip and anti-scratch performance, suitable for long-term heavy-load industrial work.
Wide Application & High Compatibility: It supports welding and assembly of various cylindrical workpieces in machinery, chemical industry, petroleum, new energy and pressure vessel industries. It can be used alone or matched with welding manipulators to form an automatic welding workstation.
Application Scenarios
This 20-ton self-aligning welding roller bed is widely used for automatic welding, assembly, turning and flaw detection of pressure vessels, boiler cylinders, oil and gas storage tanks, wind power equipment, pipeline engineering and mechanical equipment cylinders. It is essential core equipment for cylinder welding automation in modern industrial manufacturing.
Our Service
Professional Customization: Support non-standard customized roller beds according to workpiece size and working conditions.
Strict Quality Control: All equipment undergoes strict factory testing to ensure stable performance.
Full After-sales Service: Provide long-term technical support, installation guidance and after-sales maintenance service.
Frequently Asked Questions
Q1: What is the maximum and minimum workpiece diameter this 20-ton roller bed can adapt to?
A1: The standard applicable workpiece diameter ranges from 800mm to 4000mm. We can also provide non-standard customization for ultra-large or ultra-small diameter cylindrical workpieces according to your actual production needs.
Q2: Is the rotating speed adjustable? Can it ensure stable welding operation?
A2: Yes. The equipment is equipped with a VFD frequency conversion system, supporting stepless speed regulation from 0.1m/min to 10m/min. It features smooth start and stop, no jitter or impact on workpieces, and fully meets the precision requirements of automatic circumferential seam welding.
Q3: Does the self-aligning structure require manual adjustment during operation?
A3: No manual adjustment is needed. The integrated self-aligning hinged structure can automatically adjust the roller angle and fit different cylinder diameters, realizing automatic centering, which saves adjustment time and improves production efficiency.
Q4: What kind of workpieces is this roller bed suitable for?
A4: It is perfectly applicable for carbon steel, stainless steel and alloy steel cylindrical workpieces, including pressure vessels, boilers, storage tanks, wind power towers and industrial pipes, widely used in welding, assembly, turning and flaw detection processes.
Q5: What after-sales support can you provide?
A5: We provide one-stop services including factory pre-testing, door-to-door installation guidance, operation training, long-term technical consultation and equipment maintenance. Spare parts support is available for lifelong after-sales service.
Q6: Can it be matched with other welding equipment?
A6: Absolutely. This roller bed can be used independently or matched with welding manipulators, welding positioners and automatic welding machines to form a complete automatic welding production line, improving overall welding automation level.
