МАТЕРИАЛОВMATERIALS
1one
Изобретение относитс к испытательной технике и, в частности, к испытани м формовочных материалов.The invention relates to a testing technique and, in particular, to testing molding materials.
Наиболее близким к изобретению вл етс устройство дл испытани формовочных материалов, содержащее основание, закрепленный на нем полый барабан с крышками по обоим его торцам, контртело, размещенное на внутренней поверхности барабана, и привод вращени барабана 1.Closest to the invention is a device for testing molding materials, comprising a base, a hollow drum fixed on it with lids on both its ends, a counter body placed on the inner surface of the drum, and a drive for rotating the drum 1.
Недостатком данного устройства вл етс то, что оно не позвол ет проводить испытани при повыщенных температурах.The disadvantage of this device is that it does not allow testing at elevated temperatures.
Цель изобретени - проведение испытаний формовочных материалов при высоких температурах.The purpose of the invention is to test molding materials at high temperatures.
Цель достигаетс тем, что контртело выполнено в виде стержней,равномерно раз-, мещенных по внутреннему периметру барабана , жестко закрепленных в его крышках и подключаемых к источнику тока.The goal is achieved by the fact that the counterbody is made in the form of rods uniformly spaced along the inner perimeter of the drum, rigidly fixed in its covers and connected to the current source.
На фиг. 1 показано предлагаемое устройство дл испытани формовочных материалов; на фиг. 2 - сечение А-А на фиг. 1.FIG. Figure 1 shows the proposed molding test apparatus; in fig. 2 is a section A-A in FIG. one.
Устройство содержит основание 1, закрепленный на нем полый барабан 2,The device comprises a base 1, a hollow drum 2 fixed on it,
крышки 3 и 4 барабана, привод 5 вращени барабана 2, стержни 6, укрепленные торцами в крышках 3 и 4 барабана. Внутрь барабана вставлена термопара 7, а внизу установлен лоток 8 дл сбора осыпавшейс массы формовочного материала цилиндрического образца 9.covers 3 and 4 of the drum, drive 5 of the rotation of the drum 2, rods 6, reinforced by the ends in the covers 3 and 4 of the drum. A thermocouple 7 is inserted inside the drum, and a tray 8 is installed below to collect the crumbled mass of the molding material of the cylindrical sample 9.
Устройство работает следующим образом .The device works as follows.
Стержни 6 соедин ют с источником тока и разогревают до заданной температуры, а температуру контролируют термопарой 7. После этого барабан привод т во вращение от привода 5. Помещенный внутрь барабана цилиндрический образец 9 обкатывают в течение заданного времени. Под воздействием трени , ударов о нагреватели и высокой температуры поверхностный слой образца разрушаетс и просыпаетс в лоток 8. Масса осыпавшейс смеси служит мерой поверхностной прочности смеси при температуре испытани .The rods 6 are connected to a current source and heated to a predetermined temperature, and the temperature is controlled by a thermocouple 7. After that, the drum is rotated by the drive 5. A cylindrical specimen 9 placed inside the drum roll in for a predetermined time. Under the influence of friction, blows on heaters and high temperature, the surface layer of the sample is destroyed and spills into tray 8. The mass of the showered mixture serves as a measure of the surface strength of the mixture at the test temperature.
Устройство позвол ет оценить качество св зующих формовочных и стержневых материалов при различных температурах.The device makes it possible to assess the quality of bonding molding and core materials at various temperatures.
