Abstract
Description
Изобретение касается обработки поверхностей деталей. The invention relates to surface treatment of parts.
Известны элементы эжектирования мелких твердых частиц, в частности металлической дроби, обычно применяемых в известных гидродробеструйных установках, например, для упрочнения зубьев зубчатых колес авт.св. СССР N 996015, для упрочнения металлических деталей авт.с. СССР N 175992 и т.п. Known elements of the ejection of small solid particles, in particular metal fractions, commonly used in known hydraulic blasting installations, for example, for hardening the teeth of the gears of autosw. USSR N 996015, for hardening metal parts ed. USSR N 175992, etc.
Предлагаемый способ поверхностного упрочнения деталей (поршней ДВС) путем обработки дробью с модернизацией установки авт.св. 175992 позволяет повысит качество обрабатываемой поверхности деталей с возможностью обработки снаружи поршней или гильз цилиндров с повышением класса чистоты, точности, исключая финишную обработку поверхности другими методами. Достигается это тем, что эжектирование дроби осуществляют смазывающе-охлаждающей жидкостью (СОЖ) с применением вместо дроби подшипниковых шариков 1 - 2 мм с примесью порошковых присадок, а также ультразвуковых колебаний кавитационного смесителя. The proposed method of surface hardening of parts (ICE pistons) by processing with a shot with the modernization of the installation of autosw. 175992 allows you to improve the quality of the workpiece surface with the possibility of processing the outside of the pistons or cylinder liners with an increase in cleanliness class, accuracy, eliminating the surface finish by other methods. This is achieved by the fact that the ejection of the fraction is carried out by a lubricating coolant (coolant) using instead of a fraction of bearing balls 1 - 2 mm with an admixture of powder additives, as well as ultrasonic vibrations of the cavitation mixer.
На чертеже приведена схема установки для обработки поверхностей деталей описываемым способом. The drawing shows a diagram of the installation for surface treatment of parts described method.
Обрабатываемая деталь (поршень) 1 устанавливается в камере 2, разделенной сеткой 3 на две полости А и Б. В сетке 3 помещена дробь, в полости Б - СОЖ с присадкой антифрикционного материала медного порошка (CuS2) в баке 7 и ультразвуковых колебаний кавитационного смесителя 10. В полости А установлены два электрода 4, 9. В них с помощью насоса 5 подают струю СОЖ (суспензии, СОЖ), барботируя порошковую присадку с помощью барботажа 11, которая подхватывает дробь и направляет ее через эжекторы на обрабатываемую деталь (поршень), производя обработку ее поверхности. Отделенная от дроби сеткой 3 жидкость сливается по патрубку 6 в бак 7. Фильтр 8, расположенный в баке, отделяет мелкие частицы разрушенной дроби, прошедшие через сетку фильтра 8. Затем насос 5 снова засасывает жидкость и процесс продолжается. Наличие присадочного (антифрикционного порошка) проверяется специальным ареометром.The workpiece (piston) 1 is installed in the chamber 2, divided by a grid 3 into two cavities A and B. A shot is placed in the grid 3, coolant is placed in the cavity B with coolant additive of copper powder (CuS 2 ) in the tank 7 and ultrasonic vibrations of the cavitation mixer 10. In the cavity A, two electrodes 4, 9 are installed. They use a coolant jet (suspension, coolant) to be pumped with a pump 5, sparging the powder additive with a bubbler 11, which picks up the shot and directs it through the ejectors to the workpiece (piston), processing it on top awns. The liquid separated from the shot by the net 3 is discharged through the nozzle 6 into the tank 7. The filter 8, located in the tank, separates the fine particles of the destroyed fraction passing through the filter 8. The pump 5 then again sucks in the liquid and the process continues. The presence of an additive (anti-friction powder) is checked by a special hydrometer.
Обработку поверхностей деталей можно производить без наличия шариков, с помощью кавитационных каверн при увеличении давления жидкости и времени обработки. Surface treatment of parts can be done without the presence of balls, using cavitation cavities with increasing fluid pressure and processing time.
