Analysis of the technology of manufacturing a semi-finished part for a hollow part of a complex geometric form using the technology of hot volume stamping

Abstract. Background. Today, the actual issues in the production of metal products are the saving of materials and the productivity of production, as this has a significant impact on the cost of finished products. This especially applies to hollow products with a complex geometric shape. Such products include parts or semi-finished products that have hollow cavities and additional elements in the design in the form of flanges, or variable wall thickness along the height of the product. Such parts are widely distributed in mechanical engineering, aircraft construction and in the production of special purpose products, in particular in the field of ammunition production. Therefore, the manufacturing technology of such parts should ensure mass production and have an economic effect. Goal. By calculation, using the finite element method (FEM) in the DEFORM software environment, determine the option of stamping, from blanks of different diameters, a semi-finished product of a hollow part of a complex geometric shape using the technology of hot three-dimensional stamping, and analyze the proposed technological process of obtaining a semi-finished product. Methodology of implementation. Using MSE in the DEFORM software environment, simulation of hot three-dimensional stamping of a semi-finished product was carried out for a hollow part of a complex geometric shape made of blanks of different diameters. In this way, the option of obtaining a semi-finished product with a minimum number of transitions and a guaranteed possibility of implementing the technological process of mold formation was chosen. For the selected option, an analysis of the force modes of forming, normal stresses on the contact surfaces of the workpiece with the tool, and the stress-strain state of the deformed metal was performed. The results. A semi-finished product manufacturing technology for a hollow part of a complex geometric shape using hot three-dimensional stamping technology is proposed. This technology will be implemented in the production of the adapter housing part, which is used in the design of the 120 mm mine. By calculation, with the help of MSE in the DEFORM software environment, the variant of semi-finished product molding for the "Body-adapter" part was determined using the technology of hot three-dimensional stamping, and an analysis of the technological operation of semi-finished product molding was carried out. The temperature regime of the process, technological efforts, parameters of the stress-strain state of the deformed material, the distribution of normal stresses on the deforming tool are determined. The results of the conducted computer modeling make it possible to take into account the design features and select the necessary technological equipment for mass production. Conclusions. The technology for serial production of semi-finished products by hot volumetric stamping has been developed and substantiated. This technology made it possible to increase the rate of material utilization by two times compared to the technology of obtaining a part by mechanical processing from graded rolled steel.

The effect of deformation rate on the process of hot extrusion with dispensing of round hollow semi-finished products

Background. Stamping of round hollow semi-finished products by hot reverse extrusion is one of the initial operations in the manufacture of hollow products for special purposes. The force and shape change of the metal during hot plastic forming is significantly affected by the deformation rate or the speed of movement of the deforming tool. For special-purpose products, certain mechanical properties are required in the wall height and bottom part. The wall height properties are ensured at subsequent stretching transitions with thinning of the semi-finished product obtained by hot extrusion, which involves working out the metal structure by plastic deformation to achieve the required properties. Therefore, it is an urgent task to study the effect of the deformation rate on the force and shape change of the metal during hot reverse extrusion of hollow semi-finished products.Goal. To determine the influence of the deformation rate on the parameters of hot reverse extrusion with the dispensing of hollow semi-finished products from round and square billets by means of finite element method (FEM) modeling and to compare the results of theoretical researches.Methodology of implementation. Theoretical researches of extrusion power modes, specific forces, and the stress-strain state of metal were carried out by modeling using the FEM in the DEFORM software environment.Results. The FEM was used to model the process of hot reverse extrusion with dispensing of round hollow semi-finished products from mild steel with protrusions at the end of the bottom part on the side of the cavity and on the outer surface. The deformation rate was in the range of 20 to 80 mm/sec. Round and square cross-sectional blanks were used. The dependence of the extrusion force on the punch displacement was determined. The distribution of specific forces on the deforming tool was determined. The stress-strain state and temperature distribution in the deformed metal at the end of extrusion were determined. The development of the metal structure by hot plastic deformation was evaluated and the results obtained were comparedConclusions. The effect of the deformation rate on the parameters of hot reverse extrusion with dispensing of round hollow semi-finished products was determined

Research on the safety level of special-purpose knitwear products

Environmental consciousness has become an essential component of human life in 2015-2024. Therefore, innovative textile and knitwear products made from environmentally-friendly fibers are becoming popular. Such products are safe for health and have less negative impact on the environment. The safety research problem of special-purpose knitwear products remains relevant, as they are used in special conditions, in direct contact with human skin. The aim of the study was to assess the safety indicators of textile products for the manufacture of workwear entering the Ukrainian market. The study used the method of atomic absorption spectrometry to determine the presence of heavy metals and pesticides in the products. The study determined the gross content of heavy metals that are harmful to human health: cobalt, chromium, copper, nickel, tin, cadmium, arsenic, and mercury. Three knitwear fabrics made in China, Ukraine and the Netherlands were selected as samples. The pesticide content was found to be inconsistent with the regulated requirements of Oeko-Tex-100. In the fabric made in China, the level of dieldrin exceeds the permitted limit and reaches 46 μg/kg, while the norm is 0.2 μg/kg. The fabric made in Ukraine contains an unacceptable amount of heptachlor (0.75 μg/kg at a norm of 0.5 μg/kg) and lindane (β-GCG) – 3.68 μg/kg at a norm of 1.0 μg/kg. The highest level of pesticides exceeding the established norms was found in the fabric made in the Netherlands. DDE exceeded almost 4 times – 3.75 μg/kg at the norm of 1.0 μg/kg; heptachlor almost 7 times – 3.19 μg/kg at the norm of 0.5 μg/kg, lindane γ-GCG – 1.51 μg/kg at the norm of 1.0 μg/kg and β-GCG – 15.7 μg/kg at the norm of 1.0 μg/kg. It is proposed to increase the level of control of environmental certification and standardisation with the introduction of mandatory eco-labeling of workwear, and to strengthen control by customs authorities when importing special-purpose products into the customs territory of Ukraine. The results of the study can be used by customers of workwear, wholesale and retail trade entrepreneurs, and can serve as a basis for strengthening control by customs authorities and certifying bodies over the entry of special-purpose knitwear of inadequate quality and safety level into the Ukrainian market

IMPROVING THE QUALITY OF VEGETABLES AND FRUITS USING BIOFORTIFICATION STRATEGIES

An analysis of the state of nutrition of people in Ukraine shows that the population does not eat well, which significantly worsens the state of their health and working capacity. The solution to the problem is possible through changes in the structure of nutrition, and above all, through an increase in the diet of vegetables and fruits of high quality, the varieties of which have been created using biofortification strategies. Biofortification is an innovative and promising approach in solving global problems related to nutrition. The goal of biofortification is to create plants with increased levels of the necessary functional ingredients absorbed from the soil, as well as those synthesized in the plant. Biofortification strategies consist in the development of optimal ways of mineral nutrition of plants, the creation of new species using molecular genetic approaches, and the use of traditional breeding methods. The purpose of the research is to analyze the modern experience of creating varieties of various fruit and vegetable crops with the help of biofortification strategies, which have an increased content of functional ingredients. Based on the literature review, it was established that for many years, an unconventional direction of selection has been developing – the creation of varieties and hybrids of fruits and vegetables with the recommended chemical composition. Created varieties of vegetables and fruits with increased protein content (nuts and legumes); starch (potato); carotenoids, dry matter, disaccharides (carrot, pumpkin); vitamin C, betanin, sugars (table beet); selenium (tomatoes); bioflavonoids, vitamin C (cabbage vegetables); macro- and microelements (bulb vegetables), etc. Such raw materials can be used to create special purpose products, which will significantly improve the quality of the population's diet and health. It is shown that the development of the non-traditional direction in breeding remains promising, and the study of samples of the domestic collection of agricultural crops and the selection of the best varieties from them for various directions of use, and especially for the production of special purpose products, is an important national economic and scientific task of an innovative nature that must be developed, therefore that the problem of improving the nation should come first.

Исследование возможности создания композитов на основе биополимера, армированного углеродными нанотрубками, для использования их в протезировании

One of the main and fairly new materials for prosthetics are polymers. Among the most commonly used materials nowadays in the design and manufacture of prostheses are polyetheretherketones (PEEK), which have excellent stiffness and strength. They can be modified with fillers to improve their already impressive properties. This results in increased durability of the materials, so that prosthetic components remain strong and viable even after years of use. There are many ways to obtain structural materials with improved functional properties, one of which is the introduction of carbon nanotubes (CNTs) into the matrix of polymer composite material (PCM), which, having unique physical and chemical properties, modify the polymer-matrix for further use in special-purpose products. This paper presents the results of the study of the possibility of creating composites based on biopolymer polyetheretherketone reinforced with carbon nanotubes for their use as a material for prostheses that can be produced by 3D printing. The interaction of a single-layer carbon nanotube (6, 6) with a polyetheretherketone monomer and with a fragment consisting of four PEEK monomers was modeled and studied. One-center and two-center interactions have been studied. The calculations were performed within the framework of the quantum-chemical DFT method with different basis sets. The main interaction parameters were determined and the possibility of realizing the modification of the polymer by nanotubes was proved, which can serve as a stimulus for the creation of a new material that will have new unique properties for the creation of durable prosthetic limbs.

Development of a scientifically based concept for the formation of an adaptive approach to the meat and dairy socially significant production based on deep processing of regional livestock raw materials, innovative ways to increase the shelf life of products, reduce the cost of technologies, increase consumer properties of products, incl. specialized and functional, are presented. Materials and Methods. The work is based on the convergence of experiments in vitro, in vivo, in silico. All studies were carried out on advanced equipment using modern methods of chromatography, mass spectrometry, voltammetry, physicochemical and biotechnological methods. Discussion. Minor components of animal raw materials can be effective in the treatment and prevention of lot diseases. Peptides with low molecular weight obtained from bovine lactoferrin have a more significant effect on gastric mucosa protection than native bovine lactoferrin in the same concentration. Using of angiogenin isolated from dairy raw materials, or serum concentrates enriched with angiogenin have a great social and practical importance. A complex of proteinoids obtained from collagen-containing raw materials, including animal skin processing waste, as a result of deep processing, can be widely used in the compounds of various food products: jellies, sausages, chopped meat semi-finished products, etc. Improving the safety of meat quality indicators when stored in a chilled state is possible using the case of its preliminary treatment of following antiseptic solutions: magnetized and electroactivated solution – catholyte; concentrate of mineral salts obtained after electrodialysis of whey. Meat treated with these solutions is more juicy compared with control. Its emulsifying ability is more high (on average 10%), which is important in sausage production. It make possible to exclude the using of third-party chemical reagents, and to increase the physical and chemical indices of meat quality and prevent its microbial contamination. In order to produce food products with the specified quality characteristics, it is proposed to use non-traditional vegetable raw materials with regional and price availability as part of the compositions. As a result of the performed research, enriched meat and dairy products of a new generation with established physiological effects were created. The developed formulations aimed to enrich food with natural bioactive complexes of macro- and micronutrients obtained from regional plant raw materials, secondary raw materials from food manufacturers, as well as to improve the organoleptics of the finished product, reduce its allergenicity, extend shelf life, reduce the cost of technologies, increasing the availability of socially significant products, including special-purpose products, for all segments of the population, consumer attractiveness due to functional properties (various types of yoghurts, cheese and cheese products, boiled and smoked sausages, jellies, chopped meat semi-finished products). Conclusion. As a result of the research, innovative technologies have been developed for the effective processing of livestock raw materials and the creation of new types of socially significant meat and dairy products through the use of non-traditional regional sources of biologically active components.

PRODUCTION OF FUNCTIONALLY GRADIENT MATERIALS BASED ON SILICON CARBIDE AND HIGH-ALLOY STEEL USING SPARK PLASMA SINTERING TECHNOLOGY

An important scientific task of practical materials science is the production of metal-ceramic composites in the form of functional gradient materials (FGM) for special-purpose products. In this regard, a study was conducted on the application of spark plasma sintering (IPS) technology for the effective diffusion connection of SiC ceramics and high-alloy steel (grade X18R15) to obtain a combined FGM composite. In a comprehensive experimental study, the dynamics of consolidation and changes in the phase composition of dispersed SiC under conditions of different temperatures and heating rates, pressing pressure, and holding time were studied. As a result, the IPS conditions were optimized for obtaining SiC ceramics of high relative density (82%) and microhardness (500 HV) of stable phase composition. The physicochemical foundations of the formation of a strong compound of a two-component SiC-ceramic and steel system under IPS conditions without additives and using a mixture of additives in the form of a binder, a reaction binder and a damper (Ti–Ag, Ti–TiH2, Ti–Ag–TiH2 and Ti–Ag/Mo additive systems) have been studied. The structure, composition of ceramics and intermediate (binding and damping) layers, as well as the diffusion of elements at the boundary of the formed compounds in FGM composites, were studied using XRF, SEM and EMF methods. It was found that the Ti–Ag/Mo additive in the ratio of 30 wt. % Ti–70 wt. % Ag and a dense layer of Mo (thickness ~ 2 mm), acting as a damper to compensate for the temperature coefficient of linear expansion, ensure the formation of a connected FGM composite of an integral shape. The presented studies have been implemented for the first time, are promising and require further development in order to gain scientific knowledge of the manufacture of composite products for special purposes.

Investigation of the dispersion process of polypropylene glycol in perfluorodecalin

Perfluorinated polyesters (PFPE) are used as components of high-performance lubricants and oils operating in high and low temperature conditions, including in special-purpose products used in space and in Arctic conditions. To date, the methods for producing PFPE are complex processes that are quite demanding to the conditions of synthesis, which makes it almost impossible to produce these compounds commercially on a large scale. One of the promising approaches to obtaining perfluorinated esters is liquid-phase direct fluorination. Toxic, ozone-depleting solvents have been used in these processes. When they are replaced with harmless, perfluorinated liquids, for example, perfluorodecalin (PFD), another problem is found – the original polyesters are insoluble in PFD, which is confirmed by laser microinterferometry. In this regard, ultrasonic dispersion of the initial polypropylene glycols (PPGs) of various molecular weights in PFD was proposed in order to obtain emulsions for subsequent direct fluorination. The resulting emulsions were studied using gel-penetrating chromatography, dynamic light scattering and gravimetry. According to the results of the study, the values of particle sizes and emulsion concentrations were obtained over time after ultrasound, and it was also concluded that the stability of the molecular weight of PPG in the emulsion after sonification. The applicability of ultrasonic dispersion for a high specific surface area of the phase boundary in the PPG – PFD system is discussed, and the feasibility of sonification in a continuous or batch mode when implementing liquid-phase fluorination of PPG in PFD is also discussed.
