Conical Bending Machines: Form Cones, Cone Shells and Conical Heads for Hoppers, Silos and Tanks

Cylinders are only part of the story in tank and vessel work. Hoppers, silos, funnels, towers and tank bottoms all need cones, and a cone cannot be rolled like a plain cylinder. The SBFM Conical Bending Machines, listed as Conical Bending Machines by SBFM, are built for forming cone-shaped parts from flat sheet and plate with clean, accurate geometry.

What Is a Conical Bending Machine?

A conical bending machine forms a flat blank into a cone or a truncated cone. Industry sources explain that cone shells are usually made from a blank shaped like a circular sector, a fan-shaped plate cut from the developed shape of the cone. The blank is bent so that its two radial edges meet and can be welded together.

Cones can be formed on roll bending machines or on presses. One source notes that roll bending machines suit cone shells up to a certain apex angle, while very wide and shallow cones are better formed by other methods, so the right machine depends on the size and angle of your cone.

How Cones Are Formed

On a plate rolling machine, a cone is rolled differently from a cylinder. The rolls are tilted or adjusted so that the large end of the blank travels faster than the small end, and the plate is guided so that it does not slip. Industry sources describe several methods, including the use of conical rolls or tilted rolls and four-roll machines that clamp the plate, and note that cones are often rounded in several passes with pre-bending of both ends.

The product photo shows a very large, shallow cone resting on a machine in a working workshop, with faint lines running across its surface and a wide, rounded rim. A blue-and-white machine stands behind it. The photo gives no technical data, so please confirm capacity, cone angle, plate thickness and diameter range for your project directly with the manufacturer.

Key Features and Benefits

• Cone and truncated cone forming; from flat blanks
• Suitable for sheet and plate; thin and thick walled work
• Accurate geometry; cones that match the shell they join
• Wide range of cone shapes; from steep funnels to shallow tank bottoms
• Works with your tank line; dishing, flanging and rolling from one maker
• Repeatable results; each cone matches the previous one
• Made in Konya; designed, assembled and tested in our own facilities

Applications

• Hoppers, funnels and chutes
• Silo and tank bottoms
• Tank roofs and conical covers
• Process tank cones for mixers, evaporators and settling tanks
• Towers, stacks and structural cones
• Ductwork, reducers and transitions

Tips for Better Cones

Cut the blank to the correct developed shape before bending: a sector with the right radii and angle gives the correct cone. Bend gradually in several passes and pre-bend the ends so that no flat zone remains at the edges. Check the diameter and angle with a template as you go, and weld the seam only when the edges meet cleanly. For wide, shallow cones, ask the manufacturer about the best forming method before ordering.

Part of a Complete Sheet Metal Forming Range

SBFM Machinery has built sheet metal forming machines in Konya since 1998. Alongside conical bending machines, our range includes hydraulic dishing presses, flanging machines including machines for cone forms, circle cutting machines, column spinning machines, polishing machines for dished heads, hydraulic roll bending machines, profile and pipe bending machines and special corrugated and grooved rolls. That means a single partner can equip your workshop from the first blank to the finished cone, shell and head.

Why Choose SBFM Machinery?

Machines are designed, cut, welded, machined, assembled and tested in our own facilities, and our quality policy rests on customer satisfaction. We believe we grow together with our customers, so we listen first and recommend the model that fits your work, not simply the largest one. Technical guidance and spare parts help keep your machine productive for years.

How to Choose the Right Machine

• Cone angle, large and small diameters and height
• Plate thickness and material, such as carbon or stainless steel
• Largest and smallest cone you need to form
• Daily output and handling method
• Control level and safety features
• Floor space, crane capacity and power supply

Maintenance for Long Service Life

Keep the rolls and forming parts clean, check hydraulic oil, hoses and seals and lubricate moving parts. Inspect guides and supports regularly. A simple routine keeps cone geometry accurate and the machine reliable.

Frequently Asked Questions

What do conical bending machines make? Cones, cone shells and conical heads from flat sheet and plate, such as hopper cones, silo bottoms and tank roofs.

How is a cone different from a cylinder? A cylinder has the same diameter all along, while a cone narrows, so the blank is a fan-shaped sector that must be formed with different speeds and pressures at each end.

How do I choose the model? Send us your cone dimensions, plate thickness and material, and our engineers will recommend the right model.
