Description

1 .. one ..

Изобретение относитс к области литейного производства, а именно к установке дл обработ ки отливок после лить , преимущественно крупных деталей типа колес, и может быть использовано в литейных цехах машиностроительных заводов.The invention relates to the field of foundry, in particular, to an installation for processing castings after casting, mainly large parts such as wheels, and can be used in foundries of engineering plants.

Известна установка, содержаща установленный на станине вертикально-замкнутый конвейер непрерывного действи , базовое приспособление дл отливок, расположенные на индивидуальных рамах рабочие органы, приводы вращени последних и упоры.A known installation comprising a vertically closed continuous-flow conveyor mounted on a bed, a basic device for castings, working bodies located on individual frames, rotational drive drives and stops.

Недостатками известной установки вл ютс низка производительность и возможность обработки только одного типа отливок.The disadvantages of the known installation are low productivity and the ability to process only one type of casting.

С целью повышени производительности и увеличени номенклатуры обрабатываемых отлиВОк в описываемой установке базовое приспособление выполнено в виде сТупенчатых направл ющих, смонт1ированных над указанным конвейером параллельно его оси, а рабочие органы размещены с двух сторон верхней ветви конвейера в вертикальной плоскости и каждый из них выполнен в виде ротора с радиально-расположенным ударником , привод вращени которого и упоры, взаимодействующие с отливками, укреплены на раме, шарнирно закрепленной на станине конвейера.In order to increase productivity and increase the range of processed otliVOK in the described installation, the basic fixture is made in the form of Step-up guides mounted above the conveyor parallel to its axis, and the working bodies are placed on both sides of the upper branch of the conveyor in a vertical plane and each of them is made in the form of a rotor with a radially located drummer, the rotational drive of which and the stops interacting with the castings are mounted on a frame hinged on the frame of the conveyor.

На фиг. 1 изображена установка, общий вид; на фиг. 2 - разрез по А-А на фиг. 1; на фиг. 3 -разрез по Б-Б на фиг. 1.FIG. 1 shows the installation, general view; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. one.

УстаноБ1ка содержит вертикально-замкнутый -конвейер 1 непрерывного действи , имеющий станину 2, т говый орган 3 и расположенные на нем с посто нным шагом захваты 4, ступенчатые направл ющие 5, смонтированные на станине 2, кажда ступень которых предназначена дл установки, и перемещени по ним отливок 6 в определенном интервале типоразмеров, механизмы 7 дл отделени литников 8 и прибылей 9, установленные па станине 2 посредством Шарнирных опор 10 и содержащие раму 11, на которой смонтирован рабочий орган 12, выполненный в виде непрерывно вращающегос от привода 13 ротора с радиально-расположенным ударником 14, закрепленным шарнирно на пальце 15.The Ustanob1ka contains a vertically-closed continuous-flow conveyor 1 having a base 2, a traction body 3 and grippers 4 with a constant pitch 4, stepped guides 5 mounted on the base 2, each step of which is intended for installation, and moving along castings 6 in a certain range of sizes, mechanisms 7 for separating sprues 8 and profits 9, installed on base 2 by means of Hinged supports 10 and containing frame 11 on which working body 12 is mounted, made in the form of continuous rotation yuschegos the drive rotor 13 with a radially-disposed hammer 14 is pivotally secured on the pin 15.

Механизмы 7 снабжены упордми 16, жестко закрепленными на раме 11. .Mechanisms 7 are equipped with upordmi 16, rigidly mounted on the frame 11..

Дл удалени литников 8 и прибылей 9 установка снабжена разгрузочной течкой 17 с решеткой 18 и уборочными транспортерами 19 и 20.To remove the gates 8 and the profits 9, the installation is equipped with a discharge chute 17 with a grid 18 and harvest conveyors 19 and 20.

Claims

The installation works as follows. The casting 6, laid on the appropriate stages of the guides 5, is moved by the grippers 4 to the zone of action of the mechanisms 7 for separating the sprues 8 and profits 9, the working member 12 of which continuously rotates from the drive 13. The impactor 14 under the action of the centrifugal 5 force arising during the rotation of the working member 12 , always located along the radius. At the initial moment, the driving casting 6 acts on the stops 16, as a result of which the frame 11 rotates in a vertical U plane relative to the axis of the pivot bearing 10 at an angle depending on the height of the casting 6. Thanks to the stops 16 (regardless of the type of casting 6), axis 21 The working body 12 and, accordingly, the point of application of the impact force from the striker 14 are always located at the same level relative to the casting 6. When the latter moves further along the guides 5, the striker 14 strikes the casting 8 and the profit 9 from the 20 castings, which then They enter the reloading chute 17 and across the grille 18. Fall onto the harvesting conveyor 20. The molding mixture separates from the casting as a result of the impact, penetrates 25 through the grille and falls onto the harvesting conveyor 19. Formula of the invention Installation for separating sprues and profits from the castings, mainly type of wheels, containing a vertically closed continuous-flow conveyor mounted on a bed, a basic device for castings, working bodies located on individual frames, rotary actuators of the latter and stops, which so that, in order to increase productivity and increase the range of machined castings, the basic fixture is made in the form of stepped guides mounted above the conveyor parallel to its axis, and the working bodies are placed on both sides of the upper branch of the conveyor in a vertical plane and each of them made in the form of a rotor with a radially located drummer, the rotational drive of which and the stops interacting with the castings are mounted on a frame hinged on the conveyor frame.
