Description
В предлагаемом приборе дл определени сил трени между отливкой и литейной формой применен стержень-вставка с холодильниками, удал емый после заливки металла в форму.In the proposed device, to determine the friction forces between the casting and the casting mold, a core insert with refrigerators is used, which is removed after the metal is poured into the mold.
Така конструкци прибора позвол ет выт гивать отливки пр:: усадке из формы и регистрировать силу трени , перемеидение отливки н ее температуру.Such an instrument design allows the casting to be shorted out of the mold and to record the frictional force, re-moving the casting and its temperature.
На чертеже схематически показан прибор в разрезе.The drawing schematically shows the device in section.
По станине 1 на шарнирах 2 свободно перемещаетс платформа 3 с укрепленной на ней опокой 4.On the base 1 on the hinges 2, the platform 3 freely moves with the flask 4 fixed on it.
Опока 4 имеет фиксатор 5, головки 5 и 7 которого упираютс в упругую жесткую балочку 8, закрепленную на кронштейне станины прибора . На балочке 8 укреплены тензометрические датчики сопротивлени (не показаны на чертеже), соединенные в схему моста.The flask 4 has a latch 5, the heads 5 and 7 of which abut against an elastic rigid beam 8 fixed to the arm of the base of the device. On beam 8, strain gauge resistance sensors (not shown in the drawing) are attached to the bridge circuit.
Головка 9 прибора, неподвижно закрепленна на станине /, вл сь одновременно литниковой чашей и захватом отливки, соедин етс с опокой 4 стержнем 10 с заформованными в нем пластинками-холодильниками . По истечении некоторого времени после заливки металла стержень-вставка полностью разрушаетс и вместе с холодильниками удал етс . При затвердевании отливки происходит ее усадка в направлении к чаше-захвату.The instrument head 9 fixedly mounted on the bed /, being simultaneously a casting bowl and the casting grip, is connected to the flask 4 by the rod 10 with the cooling plates molded into it. After some time has elapsed after the metal has been poured, the core insert is completely destroyed and removed together with the refrigerators. When the casting solidifies, it shrinks towards the grab-bowl.
Усили , возникаюш,ие при усадке и перемещеппи отливки относительно стенок формы, фиксируютс датчиками и через усилитель записываютс на регистрируюшем приборе типа ЭПП-09, на котором одновременно производитс запись показаний термопары 11, установленной дл регистрации температуры в центре отливки.The forces that occur during shrinkage and relocation of the casting relative to the walls of the mold are recorded by sensors and recorded through an amplifier on a recording device of the EPP-09 type, which simultaneously records the readings of the thermocouple 11 set to record the temperature at the center of the casting.
Перемеш;ение отливки в форме определ ют индикатором 12 при помощи металлического стержн 13, устанавливаемого в полость формы перед заливкой.The mixing of the casting in the mold is determined by the indicator 12 using a metal rod 13 installed in the mold cavity before pouring.
№ 131866 Предмет изобретени № 131866 The subject invention
Прибор дл определени сил трени между отливкой и литейной формой, отличающийс тем, что, с целью создани возможности выт гивани отливки ири усадке из формы, между опокой и литниковой чашей применен стержень-вставка с холодильниками, удал емый после заливки формы металлом.A device for determining friction forces between the casting and the casting mold, characterized in that, in order to allow the casting of the casting and shrinking of the mold, between the flask and the sprue bowl, a core insert with refrigerators is used, which is removed after the metal is poured.
