Description

The invention relates to the processing of metals by pressure, equipment for the rolling industry, particularly ring-rolling shops.

The purpose of the invention is to increase the production quality of the resulting products, j-i

 The ria drawing shows a flow diagram of a line for the manufacture of ring yarns. .

Lines moss from the installed in the course of the technological process heating furnace 1, equipped with a receiving rack, 2, loading 3 and unloading 4 machines, a grid 5 for unloading blanks, transferring roller table 6, sedimentary press 7, roller table 8, rotary press 9, roller table 10, piercing press 11, roller table 12, rough mill 13, roller table 14, finishing mill 15, roller table 16, molding press 17 and bypass reversing conveyor 18.

Lini works in the following way. Round billets with a diameter of 200-500 mm and a length of 200-1100 mm are fed to the receiving rack 2. Then, by machine 3, each piece is loaded into the heating ring furnace 1. After heating the blanks to the deformation temperature (l 150-1270 s, depending on the brand steel) they piecemeal development manager M.Blanar

They are driven by machine 4 on pemetKy 5 and roller table 6 is fed to a 4000-ts sedimentary press 7, where sludge is made and the workpiece is distilled, after which roller table 8 is fed to a tilter 9, on which the workpiece is turned 180 °, roller 10 is fed to press 11 1000 tf force, where the central hole is pierced. The described part of the line (sedimentary tilter and piercing press) passes all ring blanks in a single stream. Further possible are the following options for the process flow of blanks (depending on the complexity, the profile of the rings); roller conveyor 12 - mill 13 - mill 15 - roller conveyor 16; roller conveyor 12 - mill 13 - conveyor 18 - press 17 - roller conveyor 16; roller conveyor 12 - mill 13 - mill 15 - roller conveyor 16 - conveyor 18 - press 17 - conveyor 18 and roller conveyor 12 - conveyor 18 - press 17 - conveyor 18 - roller conveyor 14 - mill 15 - roller conveyor 16.

At the same time, in the mill 13 (the black crate), the ring is pre-rolled in diameter and height, in the mill 15 (pure cage) - the final rolling in diameter and height, at the press with a force of 6000 ts, a profile is formed on its face surfaces in an annular billet.
