Roundo SF Flanging machine

Roundo SF 
Machine description and standard equipment
The Roundo flanging machine for easy production of flanged cylinders and pipes has four main functions.
The expanding unit
During the flanging operation, the cylinder is held in the correct position by an expanding unit. This consists of several segments with the same diameter as the cylinder, pressed against its inside. By clamping in this way, the cylinder keeps its cylindrical form. One set of clamping segments is required for each diameter range of cylinders. The flanging unit
The flanging is performed by two rolls. One is fixed and the other is hydraulically adjustable. Both rolls are driven by an electric motor with a worm gear box. The rolls are mounted vertical to the cylinder and are interchangeable for different shapes on the flange.
The supporting table
The supporting table for the cylinder is horizontal and the flanging unit is hydraulically tilted into the vertical position during the flanging procedure. The hole punching unit
The machine is supplied complete with a standard hydraulic punching unit and an indexing plate for forming different numbers of holes in the flanges. The hydraulic punching unit is parked during the flanging operation from there, it is moved into the punching position and locked pneumatically. The indexing plate has two circles with different numbers of holes. Three numbers of holes are available on each circle. The indexing is made by manual rotation and the positions are set pneumatically. The machine can be equipped with automatic indexing, turning and punching as an optional extra. The SF is a range of patented machines to produce flanged cylinders in a new way almost any flange shape on a product can be produced with the SF inachines. In addition, they are manufactured more efficiently, resulting in lower costs. They replace both the flange manufacturing by bending, welding, drilling and turning and the welding of the flange on to the cylinder. The SF inachines have many types of tooling, allowing for different styles of flange, such as grooves for sealing or different angles. Another option is producing light angle rings from sheet material. Costs can be reduced by up to half by using SF inachines instead of conventionally manufacturing flanged cylinders or pipes.
For a 500 mm diameter cylinder and a flange with holes, manufacturing time is less than 10 minutes, producing a very high quality flanged cylinder. Because the cylinder is held in the machine by an expanding unit, the tolerances on the roundness are extremely good.
