Hydraulic Dishing Press with Manipulator: Form Strong, Smooth Dished Heads with Automatic Sheet Spinning

Every cylindrical tank needs lids, and the lid is often the hardest part to make well. A flat circle of plate must be pressed into a smooth, curved head that closes the top or bottom of the container and carries its load. The SBFM Hydraulic Dishing Press with Manipulator (BSPM) is built for this job. It cambers the covers that close the top and bottom openings of pressurized or unpressurized, thin or thick-walled cylindrical containers, and it works with the aid of a manipulator, an automatic sheet spinner that turns the plate under the press.

What Is a Hydraulic Dishing Press?

A dishing press forms the curved crown of a dished head. A flat, round plate is placed under a hydraulic ram, and a die presses it in a series of strokes spread over the whole surface. Little by little the plate takes on its dome shape. Because the pressing is done cold and in controlled steps, the head keeps a smooth, even surface.

After dishing, the edge of the head is usually flanged and trimmed so that it fits the tank shell. The press therefore sits at the heart of tank head production, working together with flanging and polishing machines.

How the Manipulator Makes the Difference

Turning a heavy plate by hand between strokes is slow, tiring and hard to repeat. The manipulator solves this. It grips the plate, rotates and positions it under the die, and lets the press work around the whole surface in an orderly pattern. The result is a head with a more uniform shape, less manual handling and a safer working area for operators. The automatic sheet spinner also shortens cycle time, since the plate moves exactly where it is needed without delay. The unit shown on the machine is marked 20 mm x 4000 mm, a reference to the plate thickness and diameter range of that model.

Key Features and Benefits

• Hydraulic pressing force for smooth, powerful and controllable forming
• Manipulator (automatic sheet spinner) that turns and positions the plate
• Dished and cambered heads for cylindrical tanks and vessels
• Thin and thick-walled covers within model capacity
• Rigid welded frame that withstands repeated heavy pressing
• Consistent head shape from one part to the next
• Reduced manual handling for safer, easier operation

Materials You Can Form

The press forms plate in carbon steel, stainless steel, aluminum and other formable metals. Maximum diameter and thickness depend on the model and on the material, and harder grades need more force. Always confirm capacity for your head diameter, plate thickness and material before ordering.

Applications

• Heads for storage and water tanks
• Lids for pressurized and unpressurized vessels
• Boiler, heater and hot water tank ends
• Silos, hoppers and process tanks
• Truck tanks and tanker ends
• Food, chemical and HVAC equipment

Tips for Perfect Dished Heads

Start with an accurately cut round blank, because every later step depends on it. Keep the plate clean and free of scale to protect the die and surface. Work gradually, with overlapping strokes spread around the plate, instead of forcing the full depth in one place. Check the head against a template and allow for springback. Leave enough edge for flanging and trimming afterwards.

Part of a Complete Sheet Metal Forming Range

SBFM Machinery has built sheet metal forming machines in Konya since 1998. Alongside dishing presses, our range includes flanging machines, hydraulic roll bending machines, profile and pipe bending machines, polishing machines for dished heads and special corrugated and grooved rolls. A single partner can equip your workshop from tank heads to shells, rings and pipes.

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

• Head diameter range and plate thickness
• Material type and grade
• Whether you need a manipulator for heavy plates
• Production volume and operator skill level
• Available floor space, ceiling height and power supply

Maintenance for Long Service Life

Check hydraulic oil level, filters, hoses and fittings regularly, and look for leaks. Inspect the die and the frame for wear or cracks, since the press works under repeated heavy load. Lubricate the manipulator and guides as described in the manual and keep the area clean of scale. A simple preventive routine keeps pressing accurate and reliable for many years.
