The technology implies changing the shape and dimensions of billets due to the effect of applied forces with a subsequent result saving. The shape and dimensions of the product do not change after the pressure loss. In order to increase the plasticity, metal is heated to the specific temperature before the beginning of the treatment. The temperature is determined individually for each type of the material depending on its specific physical and chemical characteristics
An automated complex for high-precision forming of outer surfaces of non-uniform shapes. A forming tool is represented by a three-high rolling stand, in which an angle of rolls can be changed in the rolling process. The technology and equipment are flexible that allows to treat a wide range of various size blanks without changing the equipment. Mechanization of the process of the roll gap changing is possible
A multifactor model of cross-wedge rolling has been developed. Problems of controlling dimensional development of plastic forming have been solved for various technological processes of cross-wedge rolling
A high-production resource- saving technology of metal forming developed for production of solids of revolution with an extended axis and sheet blanks from construction steels, Ti, Ni, Zr, cooper, alloys based on it and other materials
The thermoplastic treatment (TPT) is a complex technology of cross-lengthwise rolling of blades combined with subsequent heat treatment. It considers design features of working elements of tillage and forage harvester equipment that have sharpened blade parts
The software automatically calculates and displays a process pattern depending on types and parameters of rolling. It determines optimal parameters of rolling at each stage by evaluating the rolling force and the assurance factor
Welding in cross-wedge rolling allows to obtain: hollow shafts (when using steels of the same grade, there is no section zone) – the strength properties of the joint correspond to the properties of the metal used, shafts with surface layers with a given thickness and purpose and a core made of steel of ordinary quality; pipes with an inner protective layer of a given thickness (stainless steels) and an outer sheath made of ordinary steel
Production of copper anode balls for the electronics industry using a new technology that combines ECAP and cross-wedge rolling
Rolling with heating of steel billets up to 873-973 K allows to improve the surface quality of rolled products by an order of magnitude and eliminate the grinding operation
Economically alloyed steel grade is universal in the price-quality relation. It enables to use it when obtaining low- and high-load gear wheels
The gravure is formed at insert forging. The production costs are reduced by 2.5 times as compared to manufacturing from rolled metal.
High durability is provided due to the formation of a wear-resistant surface layer in the process of obtaining a casting and plastic forming of an insert.
The technology is applied for forging of a gear-and-pinion set of a transmission box of the MAZ truck
Impact hydroforming is a non-punch impulse forming of sheet metal with the use of a liquid or elastic medium. Sheet forming is performed by a high-pressure pulse created by an impact of a rapidly moving hammer on a confined volume of a liquid or elastic medium (polyurethane)
The technologies of manufacturing quality forgings of parts for hip and knee implants made from titanium and its alloys, the Co-Cr-Mo alloy and the plates for the osteosynthesis of DNS, DCS and other systems made from stainless steel of 316LVM type, as well as the installing tools made from the stainless steel 40X13 have been developed and mastered. Forming of blanks, heated with high-frequency currents, is carried out through hot working by pressure.
