Изобретение относитс к порошковой металлургии, в частности к устройствам дл нанесени покрытий из металлических порошков на поверх- j ность изделий..The invention relates to powder metallurgy, in particular to devices for coating metal powders on the surface of products.
Известно устройство дл йанесени покрытий из металлических порошков , включающее источник нагрева, выполненный в виде высокочастотного Q индуктора, и узел вращени издели }.A device for detecting coatings from metal powders, comprising a heating source, made in the form of a high-frequency Q inductor, and a unit of rotation of the product is known.
К недостаткам данного устройства относитс отсутствие возможности нанесени покрытий одновременно на взаимно перпендикул рные поверхности издели .The disadvantages of this device include the inability to apply coatings simultaneously to mutually perpendicular surfaces of the product.
Наиболее близким к предлагаемому по технической сущности и достигаемому эффекту вл етс устройство дл нанесени покрытий из металли- ческих порошков, включающее корпус, нагреватель, узел вращейи и зажимное приспособление 2.The closest to the proposed technical essence and the achieved effect is a device for coating metal powders, including a housing, a heater, a rotating unit and a clamping device 2.
Недостаток известйого устройства низка плотность и равномерность js покрыти .The lack of lime device is low density and uniformity of js coating.
Цель изобретени - увеличение плотности и равномерности покрыти .The purpose of the invention is to increase the density and uniformity of the coating.
Указанна цель достигаетс в устройстве дл нанесени покрытий из 30This goal is achieved in a coater of 30
металлических порошков, включакицем корпус,нагреватель,узел вращени издели и зажимное приспособление,тем, что его корпус снабжен подпружиненными валиками, установленными с возможностью вращени вокруг взаимно перпендикул рных осей.metal powders, including a case, a heater, a unit of rotation of the product and a clamping device, in that its case is provided with spring-loaded rollers rotatably mounted around mutually perpendicular axes.
На чертеже изображена схема,выполнени предлагаемого устройства, предпочтительный вариант.The drawing shows a diagram of the implementation of the proposed device, the preferred option.
Устройство включает оправку 1, св занную с приводом вращени (не показан) при помощи токарного патрона 2. Обрабатываемое, изделие (деталь) закреплено в оправке винтом 3. ,Г-образный корпус 4 снабжен валиками 5 и 6, установленными во втулках 7 с возможностью вращени вокруг взаимно пёрпейдикул рных- осей 8 и подпружиненными цилиндрическими пружинами 9 сжати , причем пружины и оси снабжены крышками 10. Нагреватель 11 выполнен в виде высокочастотного индуктора . (Торцова поверхность обрабатываемого издели на чертеже обозначена индексом А, а внутренн цилиндрическа - индексом В).The device includes a mandrel 1 associated with a rotational drive (not shown) using a turning chuck 2. The workpiece (product) is fixed in the mandrel with a screw 3. The L-shaped body 4 is equipped with rollers 5 and 6 installed in bushings 7 with the ability to rotation around mutually perperidicular-axes 8 and spring-loaded cylindrical compression springs 9, with the springs and axes provided with covers 10. The heater 11 is designed as a high-frequency inductor. (The end surface of the workpiece in the drawing is designated by the index A, and the internal cylindrical by the index B).
Устройство работает следующим образом .The device works as follows.
Изделие (деталь) с предварительно нанесенным слоем порошка устанавливают в оправку и закрепл ют винтом. После этого оправку размещают в токарном патроне и включают высокочастотный нахфев. Изделие привод т в вращение, а затем в его внутреннюю полость ввод т корпус таким образом, чтобы валики контактировали соответственно с торцовой и внутренней поверхност ми издели . В процессе вращени издели происходит уплотнение порошкового сло подпружиненными валиками и его спекание с покрываемой поверхностью. При этом за счет одновременного воздействи температуры и давлени достигаетс высока плотность и однородность покрыти из металлических порошков.An article (part) with a pre-applied layer of powder is placed in a mandrel and secured with a screw. After that, the mandrel is placed in the lathe chuck and include high-frequency Naha. The product is rotated and then the body is inserted into its internal cavity in such a way that the rollers are in contact with the end and internal surfaces of the product, respectively. During the rotation of the product, the powder layer is compacted by spring-loaded rollers and sintering it with the surface to be coated. At the same time, due to the simultaneous effect of temperature and pressure, a high density and uniformity of the coating of metal powders is achieved.
Предлагаемое устройство опробовано при нанесении порошка типа СНГН на взаимно перпендикул рные поверхности издели (например втулки поворотной цапфы трактора), Получен fThe proposed device was tested when applying powder of SNGN type on mutually perpendicular surfaces of the product (for example, sleeves of a tractor trunnion). Received f
ное покрытие обладает высокой плотностью и однородностью.The coating has a high density and uniformity.
