Изобретение относитс к литейному производству, а именно к способам контрол заполнени опок.This invention relates to a foundry, in particular to methods for controlling the filling of flasks.
Известен способ контрол качества уплотнени опок, заключающийс в том, что в опоку засыпают формовочную смесь, уплотн ют ее и с помощью пробоотборника (калиброванной гильзы) вырезают -образец из уплотненной формы. Вырезанные образцы взвешивают и по весу образцов сравнивают качество заполнени опоки 1.A known method of controlling the quality of the compression of the flasks is that the mold sand is poured into the mold, compacted and compacted with a sampler (calibrated sleeve) and cut out a sample from the compacted mold. The cut samples are weighed and the quality of filling the flask 1 is compared by weight of the samples.
Однако известный способ позвол ет проводить контроль лишь в уплотненной форме, что дает искаженные результаты. Кроме того , отбор проб ведетс хаотично и нет возможности проводить статистический анализ полученных результатов. Способ продолжителен по времени и трудоемок при исполнении .However, the known method allows monitoring only in compacted form, which gives distorted results. In addition, sampling is conducted randomly and there is no possibility to carry out a statistical analysis of the results obtained. The method is time consuming and laborious in execution.
Цель изобретени - расширение технологических возможностей и уменьшение трудоемкости процесса.The purpose of the invention is to expand technological capabilities and reduce the complexity of the process.
Указанна цель достигаетс тем, что на опоку, заполненную формовочной смесью, накладывают шаблон, через отверстие которого пробоотборником выдел ют - пробу, после чего уплотн ют смесь в пробоотборнике с заданным усилием и по отношению величины осадки смеси в пробоотборнике определ ют качество заполнени смеси в различных местах опоки.This goal is achieved by placing a template on the flask filled with molding sand, through the opening of which a sampler is removed — a sample, after which the mixture is compacted in the sampler with a predetermined force, and the quality of filling of the mixture in various samplers places in the flask.
Способ осуществл етс следующим образом .The method is carried out as follows.
На модельную плиту устанавливают опоку , засыпают формовочную смесь, накладывают на опоку шаблон. Через отверстие шаблона внедр ют в формовочную смесь калиброванные гильзы до соприкосновени Q с модельной плитой, снабженной плунжерами с мерительными инструментами. После приложени к плунжерам заданного усили по величине осадки смеси под плунжерами суд т о качестве заполнени опоки формовочной смесью. A mold is installed on the model plate, the molding sand is poured, a pattern is placed on the mold. Calibrated sleeves are inserted through the mold hole into the moldable mixture before contacting Q with a model plate equipped with measuring tools plungers. After a predetermined force is applied to the plungers, the mixture will be judged on the quality of filling the flask with a moldable mixture according to the amount of precipitation of the mixture under the plungers.
Предлагаемый способ позвол ет быстро The proposed method allows fast
5 определить качество заполнени опоки формовочной смесью и тем самым ускорить процесс ввода новых автоматических линий, а также в 3,0-5,0 раз ускорить процесс ввода новой номенклатуры лить , что в 2,0 раза снижает брак по формовке. Способ на стадии проектировани оборудовани позвол ет выбирать оптимальные процессы заполнени опок смесью, например, среди свободной засыпки, гравитационной, пескострельной и других дл данной номенклатуры отливок.5 to determine the quality of filling the mold box with molding sand and thereby speeding up the process of introducing new automatic lines, as well as speeding up the process of introducing a new item of casting by 3.0-5.0 times, which reduces casting defects by 2.0 times. The method at the design stage of the equipment allows the selection of the optimal processes for filling the flasks with a mixture, for example, among free-fill, gravity, sandblast and other castings for a given nomenclature.
