AbstractThe purpose of the paper is to present the issues of ensuring the safety of machinery and equipment in accordance with the requirements of the Machinery Directive 2006/42/EC of May 17, 2006 on the essential requirements for machines, with regard to the sphere of their import and distribution. This issue is related to the dynamically developing trade in cheaper new machines, mainly from countries outside the EEA (including China) and is a priority for ensuring safety and protecting the health and life of users of this type of equipment in accordance with EU regulations. The use of a variety of machines in industry, in addition to general safety requirements, which may also include quality criteria, care for the environment and industry-specific safety management requirements (e.g. food, automotive, medical devices).

Hot Die Forging

The process of manufacturing a part as a semi-finished product (a forging) using hot die forging with further machining can be performed on various types of press forging equipment following several flowsheet variants. The task of selecting the best (most effective) variant is not always obvious. The paper considers the methods of the comparative estimation of the efficiency of several variants of manufacturing a forging of the same part on the basis of the following groups of indicators: metal consumption and forging force.

The process of hot die forging of AK4-1 aluminum alloy billets for the piston of an internal combustion engine (ICE) for an unmanned aerial vehicle (UAV) was simulated using the Deform-3D software package. The object of research was an ICE piston mounted on one of the UAV types of Russian production. Simulation was performed using the following parameters: tooling and billet temperature was 450 °C, ambient temperature was 20 °C, punch speed was 5 mm/s, and Siebel friction index was 0.4. Rigid plastic medium was chosen as a material model. The number of elements (6000) was selected so that at least 3 elements fit in the narrowest section of the part. Thus, as illustrated by the piston die forging, computer simulation in the Deform-3D software makes it possible to develop hot die forging processes for making aluminum alloy billets for UAV ICE pistons. At the same time, computer simulation can be used to evaluate the power parameters of the hot die forging process, study the nature of billet forming in die forging, make necessary adjustments to the virtual process, and develop the design of a die forging tool in order to select the most effective process solutions when designing a real process. The described computer simulation technique can be extended to other aluminum alloy die forgings.
