Claims (2)

1. Способ восстановления внутренней поверхности гильз цилиндров двигателей внутреннего сгорания, включающий обжатие гильзы по введенной в нее оправке с ограничителями по длине радиальными по отношению к гильзе усилиями, последующий отпуск и механическую обработку, отличающийся тем, что обжатие гильзы осуществляют прокаткой гильзы между фасонными поверхностями, расстояние между которыми постепенно уменьшают, при этом усилия обжатия превышают предел текучести материала обжимаемой гильзы.1. A method of restoring the inner surface of the cylinder liners of internal combustion engines, comprising compressing the liner by a mandrel inserted in it with stops along the length of the forces radial to the liner, subsequent tempering and machining, characterized in that the liner is rolled by rolling the liner between the shaped surfaces, the distance between which is gradually reduced, while the compression forces exceed the yield strength of the material of the crimped sleeve. 2. Способ восстановления внутренней поверхности гильз цилиндров двигателей внутреннего сгорания по п. 1, отличающийся тем, что гильза перед обкаткой предварительно нагрета в зависимости от марки материала до температуры (0,3…0,5)Тпл, где Тпл - температура плавления материала.2. A method of restoring the inner surface of cylinder liners of internal combustion engines according to claim 1, characterized in that the liner is preheated before running, depending on the grade of material, to a temperature (0.3 ... 0.5) T pl , where T pl is the melting temperature material.
