In the press-forging plant of the SE "Malyshev Plant", forged and stamped forgings such as crankshafts, shafts, rods, valve plates, axles, cones, cranks, hubs, balancers, supports, gears, flanges, forks, crowns , hooks, washers, etc., have a different configuration.
The original technology of forgings for large crankshafts of heavy diesels was developed and mastered, low-waste processes of dissected punching were developed, based on the use of operations of distribution, crimping, flanging, cross-rolling and rolling, stamping bimetallic pistons and other forgings of complex configuration.
[b] Mass of products. [/b]
Weight forged forgings ranges from 0.08 kg to 5 750.0 kg, including:
Forged forgings from 0,08 to 250,0 kg
Forged forgings from 0.15 to 5 750.0 kg.
[b] Materials. [/b]
Various types of steels and alloys are used for the manufacture of forgings, including: Steel of ordinary quality, structural and alloy steels, heat-resistant alloys, aluminum and copper alloys , ingots of carbonaceous, alloyed and stamped steels (castings from 1.5 to 10.0 tons).
[b] Heating. [/b]
Preheating of preforms before forging (stamping), mainly Gas Flame. On units ПШМ3т and 0,9т heating of preparations is carried out in electric chamber furnaces.
[b] Hardware. [/b]
Manufacturing of forged and forged forgings is carried out, mainly, on the universal equipment, including:
Punching hammers with the weight of falling parts of 0,9t, 1,5t, 2t, 3t, 5t, 6t, 10t, 16t.
Stamping crank presses with a force of 1600 tons. 2500 tons, 4000 tons.
Forging machines for 400 tp, 800 tp, 1200 tp.
Hydraulic forging press with a force of 1500 tons.
Hammers of free forging with the weight of falling parts of 0.4 tons, 2 tons, 6 tons.
