Description
В насто щее врем коробление оболочковых литейных форм устран ют прижатием полуформ к плите подпружиненными штифтам. Однако известные подобные способы сложны и пе позвол ют получать высококачественные оболочки.At present, the warping of shell molds is eliminated by pressing the mold halves onto the plate with spring-loaded pins. However, the known similar methods are complex and do not produce high-quality casings.
Дл устранени этих недостатков предлагаетс продувать оболочковую полуформу воздухом, поток KOTOiwro направл ют со стороны наружной поверхности дл выравнивани температуры отдельных слоев оболочки.To eliminate these drawbacks, it is proposed to blow the shell half-form with air, the KOTOiwro flow is directed from the outer surface to equalize the temperature of the individual layers of the shell.
На чертеже схематически изображено устройство д.т осуп1,ествлени предлагаемого способа.The drawing shows schematically the device dt opup1, the implementation of the proposed method.
Устройство состоит из дырчатой п.титы 1 с рифлено поверхностью, на которую укладывают оболочкову О полуфор.му 2 после ее отверждени . Полуформу 2 прижи.мают к поверхност плиты при по. подпружиненных штифтов 3 и 1невмо. 4. Подпруж ненпые штифты объедин ютс дырчатой плитой- 5, св занной с кожухом 6 i траверсой 7, котора под действием пневмоцилиндра может перемехцатьс вдоль (S. Воздух от вентил тора ли компрессорной сет подают в ожух при помош,и трубы 9. Он продувает оболочку и выходит через отверсти в плите / наружу, обеспечива вырав:1ивапие тел пературы отде;гьных слоев оболочки.The device consists of a perforated section 1 with a grooved surface on which the shell O of semi-half 2 is laid after it is cured. Semoform 2 prizhi.mayut to the surface of the plate at. spring pins 3 and 1 nevmo. 4. The spring pins are joined by a perforated plate 5, connected to the casing 6 i by the cross beam 7, which under the action of the pneumatic cylinder can shift along the length (S. Air from the fan or the compressor set is supplied to the furnace by means of the pump) and pipe 9. It blows the shell and out through the holes in the slab / outward, providing the following: 1 тел ие тел тел от от detachment layers.
Правильну О плиту ре ;омендуетс изготовл ть из малотеилопроводного материала (дерево, асбестит и др.).Correct About the stove re; it is recommended to be made from a low-conductive material (wood, asbestos, etc.).
П р е д м е т j з о б р е т е н и PROPOSAL J O CO RETURN
Способ устранени :оробле1 И оболочковых лите1и Ь х форм с использова - ием прижати полуформ к плите одпруж 1ненными итифта-, .ми, о т л и ч а о ш;и и с тем, что, с целью упрошени способа и повышени качества оболоч и, оболочковую полуформу продувают воздухом с направлением потока со сторопы наружной поверхности, обеспечива выравнивание температуры отдельных слоев оболочки.Method of elimination: orbol1 of shell molds of Lx forms using pressure of the half-form to the slab with the use of one-time itifers, them, and with the aim of simplifying the method and improving the quality of the shell and, the shell half-mold is blown with air with the direction of flow from the outside surface of the stop, ensuring the temperature equalization of the individual layers of the shell.
