Summary. The main defects of plowshares are beam wear and loss of the normalized sizes of the penetration part. For troubleshooting it was recommended to replace the worn area by the new one by sticking bits of heat-treated to a hardness of not less than 45 HRC, which is made from decommissioned spring sheet. That is why, the aim of the work was to optimize the selection of spring sheets of different vehicles based on their width and thickness, according to the wedge-shaped part, and the maximum width of the beam wear; as well as to analyze the hardness of spring sheets from the possibility of their use as a wear-resistant material. To achieve the objectives it was carried out the precise measurements of culled plowshares to determine wear and was analyzed the dimensions of the spring sheets of domestic cars and other vehicles. Hardness inspection was performed by Rockwell. As a result of this work it was substantiated the rational use of rejected spring sheets as material for bits restoring of plowshares method of welding; it was identified brand of hardware (UAZ, GAZ, ZIL, KamAZ), springs of which can be used for the technology according to their dimensional parameters. The hardness of the used sheet located in the range 44-48 HRC, which is 2 times higher than the value of this index in the domestic production. It was shown that the adaptation of spring plates as secondary raw materials can minimize the complexity of the technological process of repair and its cost, and to increase the resource of details 1.8-2 times.
Keywords: plowshares, consolidating the recovery, secondary raw materials, spring sheets, hardness, wear, bits, cost, resource, dimensional parameters.
