(54) METHOD OF MANUFACTURING RING PRODUCTS

one

The invention relates to the processing of metals by pressure, in particular to the manufacture of ring articles, and can be used in the manufacture of bearing rings.

The known method of manufacturing ring products is that the piece cylindrical billet is deposited, then an annular forging is formed from it, a complete forging is stamped from the obtained forged ring, containing at least two annular blanks of different diameters, and then divided into separate ring products 1.

The disadvantages of this method are the limited product range and the increased metal consumption.

The aim of the invention is to expand the range of products obtained and increase the economy of the metal.

This goal is achieved by the fact that according to the method of manufacturing ring products, including the operation of precipitating a piece cylindrical billet, forming a ring forging, stamping a complete forging containing at least

.more, two ko, 1i, common billets of different diameters and sectioning it into separate stamps, before / after complexing :; i forgings ko, 1tstsv-n) forgings subjected to rolling.

The drawing shows a flow chart for manufacturing ring products.

The method of making ring products is. that a piece cy10 cylindrical billet 1 is deposited, receiving a forging 2, then we form an annular forging 3 from it, otde 1, a waste in the form of a bottom 4 from it. 15 forging 3 increases the diameter of the rolled annular billet 5, bringing it to the required size. At the same time, rolling allows to obtain ring blanks of a wide range of sizes for subsequent stamping of the compact blanks. From the rolled annular billet 5 a complete forging 6 is punched, containing, at least, two annular billets of different diameters. Complete forging 6

Dislike for individual ring products large 7 and small 8 rings.

An example of the method.

In the manufacture of the outer and inner rings of the bearing 807713, an initial heated piece cylindrical billet of 080 mm and a height of 100 mm is upset to a height of 45 mm. An upright ring with an outer 0122mm, inner 056mm and a height of 45 mm is formed from an upset billet. The ring forging is subjected to rolling to the dimensions of the rolled ring outer 0 154 mm, inner 0 62 mm and height 46 mm. Then, a complete forging 6, consisting of two ring blanks, is punched from a rolled billet and divided into separate ring products: a large 7 and a small 8. Both ring products are outer and inner ring 077 3 overlays with outer Kc) yibi dimensions: lff4fHbm diameter is 154 mm, the inner ../iU j "; ej rGo collar 111.5 mm; height 7.5 mm; in n the ring of its ring: outer diameter-p burt 111.5 .mm; inner diameter 62 mm; . Height 57 mm.

The use of the proposed method of manufacturing ring products allows a considerable increase in the range of sizes of the obtained complete blanks from one blank, which increases the efficiency of the process.
