ROLLING

To give metal sheets and profiles of cylindrical shape, we use rolling.

Rolling of sheet material, and pipes of various diameters, thickness and cross-section made on a special rolling roll-bending machines (rollers) that allows us to form canopies, composite columns, rounded friezes and so the Application of this technology involves deformation of sheet metal or profile in one direction due to the large fillet radius of the bend. Material (metal sheet), passed through rollers rolling machine takes the form of a cylinder.

In fact, rolling (rolling metal) is a technology for deformation of metal by means of special tools or equipment (the so-called plate bending rolls). Waltz (also known as a skating rink or roll) is a working part of the machine (machines), consisting of several rotating in different directions rollers. Between them and moves the processed material. Rollers have a limit on the thickness of the metal and the minimum radius of rolling.

Rolling metal is widely used to shape ductile metals, and the result is a finished workpiece and parts suitable for subsequent connections. When the rolling material (metal) deformed by a specified angle, acquiring a cylindrical shape.

There are two main areas of metal rolling:

• Rolling pipe (flare), which changes the radius of the tube in the tube sheet with the aim of forming a tight connection of flared tubes and grates. The process of flaring is performed in 3 stages. First of all, define the distance between the grill and the tube, then the deformation of the pipe and grates, then lift the load from the pipe surface. Because pressing guarantees the tightness of the resulting connection.
• Rolling of metal rod and sheet metal (rolling in radius). This procedure is sheet metal bending is performed while rotating the sheet metal near the roller. And for sheet metal thickness up to 10 mm heating is not needed; otherwise, (sheet metal thickness over 10 mm) will require additional heating. In the rolling radius can be used for ferrous, galvanized, stainless steel metals with different thickness of the material. At the same time increase the thickness of the metal sheet, the radius of the product after performing the rolling is reduced.

How's the rolling process:

1. The calculation of the length and the radius of the workpiece
2. Equipment is configured
3. According to the calculations of the workpiece is given the desired size (rolling process)
