FEATURES OF DEVELOPING SPECIAL EQUIPMENT FOR SHF STRENGTHENING TREATMENT OF METAL PRODUCTS MADE OF HARDENED POLYMER COMPOSITES

The prospects of using polymer composites (PC) in the designs of various technical systems are shown. Based on the analysis of PC disadvantages, the relevance of using methods of their physical strengthening modification is determined. The expediency of strengthening as the final operation of the technological cycle to eliminate the influence of subsequent treatment processes is noted. The prospects for the effect of a microwave electromagnetic field on the PC as a part of SHF product are justified for this purpose. The structural schemes of SHF technological installations with chambers of various types are analyzed in relation to their use for the simplified treatment of large-sized and complex-shaped products made of PC. It is indicated that there are no industrial samples of SHF installations suitable for strengthening a wide range of products, especially large sizes and complex shapes. The expediency of developing automated installations based on a beam-type camera with unlimited volume (radiation into an open space) is shown. The paper objective is to substantiate and develop requirements for a universal SHF technological installation for strengthening treatment of a wide range of products in size and shape, including a beam-type chamber with unlimited volume and programmable drives for relative displacement of the horn radiator and the product. Using the results of previous studies of the features of PC strengthening in a SHF electro-magnetic field, principles for creating SHF technological devices for strengthening treatment of various PC products are proposed for the first time. The results of developing a mock-up demonstrator of a mobile robotic complex for SHF treatment of large-sized products of complex shape are presented. The main provisions of engineering solutions for constructing an industrial model of a robot with SHF technological module, which has the ability to move along X-axis within the production room (on average 6m) and the range of movements of the horn emitter along Y and Z axes up to 4m. The technical novelty of the sample is confirmed by 2 patents of the Russian Federation for the invention and a utility model.
