Известен способ прокатки порош.ковых материалов , включающий уплотненпе порошка между вращающимис валками на подложке, при это,м 1нодлож1ку непрерывно подают в зону захвата валков. Однако по известному способу невозможно непрерывное пзготОВление полых изделий, кроме того качество прокатанных материалов, полученных по известному способу, низкое.There is a known method of rolling powdered materials, which includes compaction of the powder between rotating rollers on a substrate, at the same time, it is continuously fed into the zone of capture of the rollers. However, by a known method it is impossible continuous production of hollow articles, moreover, the quality of the rolled materials obtained by the known method is low.
С целью о;бес.печени непрерьиностп процесса прокатюи полых изделий и повыщенн их качества ,по предложенному способу порошок вместе с подложкой прокатывают на неподвижной оправке.With the aim of uninterrupted rolling of hollow products and improving their quality, according to the proposed method, the powder together with the substrate is rolled on a fixed mandrel.
Способ реализуетс следующим образом.The method is implemented as follows.
Про,катку трубч-атых изделий осуществл ют на стане, снабженном четыр-ьм , образующими за крытый калибр. В этом калибре расположена цилиндрическа оправка с зазором на сторону, равную толщине стенки про (Катьгв аемой трубы. Ось оправки перпендикул рна ос м прокатных валков. В верхней части оправки расположен механизм подачки подложки по оправке в очаг деформации. НаA pro, roller of tubular products is carried out on a mill equipped with four to nine, forming an indoor gauge. In this caliber there is a cylindrical mandrel with a gap on the side equal to the thickness of the wall pro (tube of the pipe. The mandrel axis is perpendicular to the axis of the rolls. In the upper part of the mandrel there is a substrate feeding mechanism along the mandrel to the deformation zone. On
валках уста новлен бункер дл подачи порошка .A powder feed hopper is installed.
Прокатываемый порошок подают в «алибр между валками.Rolled powder is served in the “alibr between the rollers.
На неподвилчную оправку подают подложку , например, полиэтиленовую пленку. При вращении валков происходит прокатка порошка между валками и подлож1кой, котора непрерывно скользит по оправке.A substrate, for example, a polyethylene film, is fed to a non-submill mandrel. As the rollers rotate, the powder is rolled between the rollers and the substrate, which continuously slides along the mandrel.
Процесс прокатки завершаетс спеканием труб и их резкой на мерные длинны.The rolling process is completed by sintering the pipes and cutting them to length.
Предложенный способ прост и надежен, допускает полную а втоматизацию процесса производства .The proposed method is simple and reliable, allows full and automation of the production process.
