Flange (flanging)

«ОЛАНД ПРОМ ІНЖИНІРИНГ» пропонує пservice: flanging (flanging) of flat and conical bottoms by cold running. Scope: chemical, woodworking, food and other industries, where the design of tanks is subject to increased requirements for rigidity and absence welded joints. Flanking of bottoms is also used to reduce wall thickness promising to save material. Principle of operation: Providing the required radius is carried out by gradually squeezing the edge of the bottom on the forming roller in the interaction of hydraulic and electrical systems of the machine.

Production and supply bottoms for tanks, capacitive equipment, vessels and apparatus.

Flat and conical bottoms can be made at our factory with the following parameters of diameters and wall thickness:

Diameter: from 600 to 3500 mm
Wall thickness: from 1.5 to 16 mm

Characteristics of the machine for flanging (flanging) and radial cutting of sheet metal:

Flange (flanging)

Maximum sheet thickness at 500 N / mm²

16 mm

The maximum diameter of a round workpiece

3600 mm

Open gap in the housing (workpiece height)

1000 mm

The diameter of the blades of the cutter

250 mm

Speed of running-in (cutting), standard

12 mm / min

Equipped with an inclined shaft for the lower cutter, which provides clean cutting of the inner and outer diameters of roundings and rings, as well as reduces the wear of the edges of circular knives

Automatic or semi-automatic operation with cam control or CNC.

High cutting accuracy due to automatic entry into the cutting wheel and rigid mechanical connection between the machine body and the clamping arc.

Designation of parameters of flat and conical bottoms:

Technical data, abbreviations:

D_o = outer diameter of the bottom

D_i = inner diameter of the bottom

CR = radius of curvature

KR = flange radius

SF = board height

DH = height of the curved part

TH_i = total height of the bottom from the inside

t = wall thickness
