SU573311A1 - Method for manufacturing grooved panels - Google Patents

Description

The canl in the sol of the location of 11p and ivlvar1) (m, for example, compressed with nozauch) is used.

In the production process, m (1) both homogeneous (ayyuvki sheet and tube pipes (for example, digital laioiOBKH AD1) and heterogeneous (for example, sheet blanks) should be used.

from HELL 1, tubular billet from LMG 2).

Kashvki can be formed at once on two sheet blanks with their total depth, also equal to the thickness of the flattened pipe billet. In addition, in the package can be located several flattened tubular blanks.

For example. Assemble a package consisting of a sheet of billet of the brand HELL 3 mm thick without a groove, a sheet billet also of aluminum AD1 5 mm thick, with a groove 16.7 mm wide and 2.1 mm deep and a flattened AMg2 tubular width 16.7 mm and 2.1 mm thick with an anti-weld layer 0.1 mm thick deposited on its inner surface. The dimensions of the tubular billet before flattening are 100 mm, and that of the wall is 1 mm.

The assembled package is rolled at 450-470 ° C in four passes with a relative compression in the first passage of 30-40% to ensure the welding of the blanks to a final thickness of 2 mm. Then a channel was formed, the wall of which is 1 mm.

The use of the proposed method of manufacture4

II panels with cables as compared to with six: W with w methods provides an increase in the quality of the panels by improving the tension of the package in the rolling process and eliminating the formation of breaks on the panel walls: better than the panels with high strength properties of the channels; the use of a broad diagnosis of material compositions; reduction of waste material when cutting edges with discharges and improving the accuracy of the location of channels.

Invention Formula Method 11goods; 1sh1 panels with channels, including assembling a package of two sheet blanks and a tubular blank between them, applying an anti-welding layer to its inner surface, rolling the package and decorating a channel, characterized in that, to improve the quality of the panels by improving in the rolling process and eliminate the formation of gaps on the panel walls, before assembling the bag, the tubular billet is flattened until the inner walls touch, and on one of the sheet blanks OK form a groove width and depth equal to the width and thickness of the flattened tubular billet.
