SU1233976A1 - Billet for manufacturing bimetal rods - Google Patents

Description

From (k), retsenia refers to the processing of metals by pressure, in particular to npeccoi a-stump of bimetallic rods from powder materials.

Lie: ib of isobregnation is better than the quality of bimetallic rods and an increase in the output of 1 second.

Phi1 1 shows a zagar with a glass in the form of a truncated cone; on fi | -. 2 the same, as part of a hollow 1air.

The blank consists of two points I, the top 2 and the bottom 3 krpepp. A core 4 is welded to the upper arm 2. A cup 5 is installed between the core and the lower lid 3. The space between the main armor, the back, 1 core, the core and the cup is locked by the nopoHiKOM 6.

When pressed, it takes place in 1 piping of porosity 6. Core 4 begins to move and squeezes cup 5. Poropuk 6, squeezing, does not slow down, all of which are replaced by akan 5.

When the cup 5 is completely removed, the sop is compacted, and the core 4 is unbroken into the lower cut 3.

Claims (1)

Billet for the manufacture of bimetallic rods, made in the form of a hollow cylindrical shell, hermetically connected to the upper and lower covers, installed coaxially with the shell and inside the core, connected to the top cover and placed between the shell and the core of the filler-powder, characterized in that in order to improve the quality of the bimetallic rods and increase the yield, it is equipped with a thin-walled glass made ι placed between the bottom cover and the core coaxially with it; in the form of a truncated cone, the smaller base of which faces the core and is equal to the diameter of the core, and the larger base is equal to 1.2-1.4 of the diameter of the core, while the height of the glass is determined by the curve ___ 3 // (1 K) ι /) 'Д' __________, ^h ~ 3 (D ^J - d ² + d ^? - Λ.1 (</ '· άφ + d *) K where Λ is the height of the glass; H is the distance between the covers; d — core diameter; D is the inner diameter of the shell; d] is the diameter of the larger base of the cone; K coefficient taking into account the compaction of the powder. fig t
