Description
В ОСНОВНОМ авт. СБ. № 131866 описан прибор дл определени силы трени между отливкой и литейной формой, состо щей из опоки, укрепленной на платформе, свободно перемещающейс по станине. Опока имеет фиксатор, упирающийс в упругую жесткую балочку, на которой закреплены тензометрические датчики сопротивлени . Усили возникающие при усадке и перемещении отливки относительно стенок формы , фиксируютс тензометрическими датчиками. Такой прибор позвол ет определить силы трени между отливкой и литейной формой, возникающие лищь при свободной усадке отливки.BASIC Auth. Sat No. 131866 describes an apparatus for determining the frictional force between a casting and a casting mold consisting of a flask mounted on a platform freely moving along a bed. The flask has a latch abutting against an elastic rigid beam, on which strain gage resistance sensors are attached. The forces arising from the shrinkage and movement of the casting relative to the walls of the mold are recorded by strain gauges. Such a device makes it possible to determine the friction forces between the casting and the casting mold, which appear when the casting shrinks.
Описываемый прибор дл определени силы трени между отливкой и литейной формой позвол ет измерить усили сопротивлени материала формы при усадке отливки, котора вследствие своей конфигурации не может свободно скользить относительно стенок формы, г вследствие наличи выступов или утолщений упираетс на отдельных участках в стенки формы.The described device for determining the friction force between the casting and the casting mold makes it possible to measure the resistances of the mold material during casting shrinkage, which due to its configuration cannot freely slide relative to the mold walls;
Достигаете} это тем, что отливка-образец, заливаема в форму, снабжаетс ребрами, установленными перпендикул рно ее продольной оси, которые не допускают свободного скольжени отливки относительно стенок формы при усадке. При этом создаетс возможность измерить тензометрическими датчиками величину сопротивлени материала формы перемещению отливки, имеющей выступы, при ее усадке. Зна это сопротивление, можно определить внутренние напр жени , возникающие в отливке при ее усадке.This is achieved by the fact that the sample casting into the mold is supplied with ribs installed perpendicular to its longitudinal axis, which prevent the casting from sliding freely relative to the walls of the mold during shrinkage. This makes it possible to measure with strain gauges the magnitude of the resistance of the mold material to the movement of the casting, which has protrusions, during its shrinkage. Knowing this resistance, one can determine the internal stresses arising in the casting during its shrinkage.
Измен форму образца, можно найти оптимальную конфигурацию отливки, при которой внутренние напр жени при усадке окал ;утс мини .мальными, что снизит веро тность образовани гор чих трещин и отливках.By changing the shape of the sample, it is possible to find the optimal configuration of the casting, in which the internal stresses during shrinkage are minimized, which reduces the likelihood of hot cracking and casting.
Промышленна полезность прибора отмечаетс НИИлитмаш.Industrial utility of the device is noted by NIIlitmash.
