ABOUT COMPANY PRODUCTS SERVICES PURCHASE AND SERVICE SHAREHOLDERS PRESS CENTER CONTACTS PRESS-FORGING SHOP home About company Production The forging and pressing shop is located in a separate building with a total area of 24975 m 2 , which was put into operation in 1983. The production capacity of the workshop is 46,000 tons / year. KPZ is intended for the production of hot forgings of engine parts and gearboxes of heavy vehicles. The press-forging shop is divided into the following departments (production): Procurement department Cutting of rolled metal up to Ø 50 mm is carried out on press-shears with a force of 500 tons in a cold state. Cutting of rolled stock into blanks of gears, shafts and crankshafts is carried out on automatic and semi-automatic bandsaw machines. The maximum possible size of the cut steel - Ø 420 mm. Recycling of end scrap of rolled metal is carried out at the open-die forging section on hammers with MUF 400 kg and 1000 kg. Press-forging department Processing of cut blanks is carried out on nine mechanized lines based on crank hot stamping presses with a force from 1600 tf to 6500 tf. Forgings are manufactured in weight from 0.8 to 50 kg, with a diameter of up to 300 mm. Forgings of crankshafts weighing up to 250 kg are made on a mechanized line using steam-air stamping hammers with MFR from 10 to 25 tons and gas heating. Forgings of gearbox stepped shafts are manufactured at a wedge rolling mill. Shaft sizes: Ø from 80 to 110 mm and length from 300 to 600 mm. Original forgings with an extended axis are manufactured at the gas condensate field with a force of 800 tf using gas heating. The maximum diameter of the upsetting part of the forging is up to 105 mm. Forgings of the "forks" and "rocker arms" type are made on PShM-3.15 t using gas heating. Forgings of connecting rods are made on the automatic line "Komatsu" with subsequent volumetric hardening, shot-cleaning, embossing and control of surface defects. Forgings weighing from 3 to 10 kg. Thermal department Forged forgings undergo preliminary heat treatment (annealing, normalization, volumetric oil quenching followed by tempering) in gas and electric furnaces. Cleaning of forgings from scale is carried out in shot-blasting drums and chambers. About company Products Contacts The address: 152300, Yaroslavl region, Tutaev, st.
