Jinbolida Hydraulic Roll Forming Machine – Heavy-Duty Forming for Thick and High-Strength Steel

The Jinbolida Hydraulic Roll Forming Machine is built for the jobs ordinary roll formers struggle with: thick plate, high-strength steel and abrasion-resistant grades that need very high, steady forces. A high-flow hydraulic power unit drives the whole line, from the decoiler and leveller through the forming stands to the cut-off. Hydraulic support on key forming stands prevents shaft deflection under heavy loads, hydraulic cylinders control over-bending precisely to counter springback, and a heavy-duty hydraulic shear or die cuts thick profiles cleanly. With intelligent valve blocks and sensors, the system responds quickly, runs quietly and allows stepless pressure adjustment.

How Hydraulics Are Used Along the Line

• Decoiler: Hydraulic motors drive the decoiler for smooth back tension on heavy coils
• Leveller: Hydraulic cylinders set the roll gap precisely, with a constant-pressure mode that flattens uneven thick plate
• Forming stands: Adjustable hydraulic side support on the bearing housings of critical stands prevents roll shaft deflection
• Over-bending: Hydraulic cylinders apply and release a precise over-bend at specific passes to compensate for springback
• Cut-off: A heavy-duty hydraulic shear or die delivers high, smooth shearing force for clean, flat, low-distortion ends
• Punching and embossing: Hydraulic units punch large holes or emboss bosses in-line where needed

Why Hydraulic?

• High force: Handles materials that need very high forming and cutting forces
• Smooth, steady power: Consistent force for stable forming of heavy material
• Precise control: Over-bend and stand support can be adjusted accurately in ways that are hard to achieve mechanically
• Clean cuts on thick sections: Hydraulic shears deliver high force quickly for flat, low-distortion ends

Applications

• Heavy structural sections from thick steel
• Profiles in high-strength and abrasion-resistant steel

Frequently Asked Questions

• What materials is it designed for? Thick plate, high-strength steel and abrasion-resistant steel that need high forming and cutting forces.
• How does it keep thick sections accurate? Hydraulic side support on key stands prevents shaft deflection, and hydraulic over-bend control compensates for springback.
• What cutting method does it use? A heavy-duty hydraulic shear or die, giving clean, flat ends on thick profiles.
• Can it punch or emboss in-line? Yes. Hydraulic punching of large holes and embossing can be added.
• What should I send for a quotation? Profile drawings, material grade, strength and thickness, strip width, required lengths and output, punching or embossing needs, and your local voltage and frequency.
