FIELD OF THE INVENTION The invention relates to foundry, in particular, to automatic production lines for cast casting

A known automatic casting line for the production of castings, comprising a pairing unit installed in a technological sequence, a tilting and drawing mechanism, a tilter, a form assembler, lifting and receiving tables, and vehicles: roll tables, walking conveyors, etc. one.

A disadvantage of the known line is the cascading arrangement of the live rolls and the CToJiOB receivers of the same functional area (when feeding and returning the model plate, it is repeatedly lowered onto the roller tables by the reception tables), which leads to an increase in the height of the roller tables and the need to raise or lower articulated or built-in process equipment.

An automatic mold making line is also known, which includes a steamer with a flask installation mechanism, a tilter, a lifting roller table, a knockout installation with a collider, a tool transfer mechanism and transport branches {2.

Closest to the invention to the technical essence and the achieved result is an automatic line containing a forming section with a vibrating table, a mixer, a section, curing the excess mixture with a cutting mechanism, a mold collector, a pouring branch of a mold, a knockout installation, a pairing mechanism with an opok mounting mechanism, a tilter, lifting roller conveyors, a tool transfer mechanism and transport branches for cooling forms, returning sub-plates and accumulating assembled forms 3.

The disadvantage of this line is that at the intersection of the transport branches pass one above the other at different levels, which increases the height of the conveyors, leads to the need to respectively raise the articulated or parallel it equipment and transport branches departing from it, increases the intensity and intensity complicates the design of the line, impairs its maintenance, especially in the intersection of the transport branches.

The whole of the invention is to simplify the design and improve the service.

The goal is achieved by the fact that in an automatic line for the production of castings containing a molding section with a vibrating table, a mixer, a solidification section with the Cutting mechanism of the mixture, collection of HK molds, a casting branch, an embossing unit, a steamer with a flask mounting mechanism, a tilter, lifting rollers, mechanisms transfer of equipment and transport branches of cooling of forms, return of additional panels R accumulation of collected

forms, the return branch of the bottom plates is located under the transport branch of the molds and at the exit from the subfloat it converges in one zone and at the same level with the transport branch of accumulation of the assembled forms, and in this zone the mechanism of transfer of the equipment is installed with the possibility of interaction of the said transport branches.

Such a mutual arrangement and implementation of transport branches and embedding in .., the zone of convergence of their segments, the mechanism of transfer of the equipment makes it possible to reduce the height of supports of the branch branches, simplify their design and reduce metal consumption; simplify the integration of technological equipment between transport branches.

Reducing the height of transport branches improves the conditions for line maintenance and repair, and improves access to its nodes.

FIG. 1 shows an automatic line for the production of castings in plan, a general view; in fig. 2 shows section A-A in FIG. one; FIG. 3 is the node I in FIG. one; in fig. 4 shows a section BB in FIG. 3; in fig. 5 is a section through BB in FIG. 3

The automatic casting production line (Fig. 1) consists of the transport branch 1, returning the x-panes, the steamer with the flask setting mechanism 2, the transport branch 3 feeding the model chit with flasks, the vibrating table 4, the mixture preparation unit 5, the transporting curing branch 6 mixture, cut-off mechanism 7, mechanisms 8 I; 9 tooling transfers, transport of the 10th branch of the return of the submodel plates, the swivel-stretching machine 11, the transport branch 12 of the finishing of the half-molds, the transport branch 13 of the rods, the collector of the forms 14, the transport branch of accumulation of assembled forms, the transport branch 16 of metal casting, lifting roller tables 7 and 18, transport forms for cooling the mold 19, a knockout unit with a steel 20 and a transport branch 21 for returning the bottom plates, located under the transport forms 19 for cooling the molds (Fig. 2), which, when exiting from it The right angle) intersects with the transport branch 15 Accumulating the assembled forms.

Crossing the transport branches of the return of 21 pit plates and piling 15 assembled forms are made split as separate segments of transport branches, which converge in one zone, on the same level, and in this zone the mechanism 8 of the transfer of equipment is embedded. The specified location of the transport branches 15 and 2 and the mechanism 8 of the transfer of the stowage provides alternate riding tooling in the same plane along both transport. - The "Gear transfer mechanism 8 (Figs. 1, 3, 4 and 5) consists of two sections of elevating drive roller tables 22 and 23 located at right angles to one another and having the possibility of alternately using an actuator (not specified) the rise of the rollers at the same height, providing a ride tooling in the same plane. The tool transfer mechanism 8 allows alternately passing assembled forms in one direction of Lenin or in the transverse direction of the submersible plates. When moving the base plate from the mold collector 14 to the swiveling machine 11, the mechanism 8 of the gear transfer equipment carries out its transfer at a right angle. When moving on-line equipment from one transport branch to another, the transfer mechanism 9 of the equipment carries out such a transmission at a right angle. The transport branches of the line consist of sections of drive roller tables. Lini works as follows. The steamed flasks, which arrived on the transport branch 1 of the return of embossed flasks, are fed under the steamer with the mechanism 2 for setting the flasks on the transport branch 3 of the sub-model plates with flasks. With the help of a steamer with a mechanism for installing 2 flasks, the flasks are steamed and one of them is mounted on a submodel slab. Then the submodel plate with the flask goes to the vibrating table 4, for the mixture preparation installation 5. With the aid of this equipment, molding sand is prepared, filled with flask and compacted. Filled with a mixture of flask on a submodel plate, enters the transport branch 6 of the mixture to solidify, where during the transfer, the mixture hardens in a burst. When passing under the cutting mechanism 7, the mixture is cut off flush with the flask. After this, the flask with the mixture on the submodel slab enters the transport branch 10 of the submodel slabs, under the swiveling machine II, which, the edge, transfers them to the charging, received from the transport branch 21 of the backfill panels and located on the roller conveyor of the transport branch 12 the finishing of the half-molds, and then, after stretching, returns the sub-model plate to the return transport branch 10 of the sub-model plates, on which the sub-model plates are accumulated and moved to the transport branch 3 of the sub-model s, plates with flasks on the installation position of the flasks in the molding plates. On the transport branch 12 of the finishing of the half-molds, coloring and drying of the half-molds is carried out with the help of dyeing and day chambers (not shown). After the half-form has been finished, a wide-spreading branch 13 of the rods is inserted, in which the lower semiformes are used to propose the rods with the help of mechanization tools that are not part of the line. Next, with the help of assembly forms 14, the canting of the upper half-form is made and its installation on the lower half-form, with the EG, the secondary plate, on which the upper half-form was transported, is moved to the swivel-sliding machine IIJHHe II. During its movement, the substation plate passes through a segment of the transport branch 15 of accumulated forms located between the mold collector 14 and the snap-in mechanism 8, and using the transfer mechanism 8 the snap-in gear is transmitted at a right angle to the segment of the return branch 21 of the stoker plates which is located between the mechanism 8 gears of equipment and a turning-and-spreading machine I. Through the same mechanism, 8 gears of equipment, with transfer in the straight line direction (the transport branch 15 accumulates the collected forms) The above-mentioned segment of the transport branch 21 of the return of the firing plates also transfers the ward plates from the knockout unit with the pusher 20, the passage along that segment of the transport branch 21 of the return of the firing plates, which is located under the transport cooling branch 19 and then goes out from under it at a right angle. to the mechanism 8 transfer equipment. The assembled forms arrive at the transport branch 15. an accumulation of the assembled forms and, when it is filled, cross the transport branch 21 of returning the podochnyh plates, the passage through the tool feeding mechanism 8 in the straight line direction. From the transport branch 15, the accumulation of collected mold forms are transferred to the transport branch 16 of the metal casting of the molds. Metal-filled molds with the help of a lifting roller table 17 lift onto the transport branch 9 of the mold cooling. The cooled molds with the help of a lifting roller table 18 are lowered and fed into the embossing installation with the collider 20. Using the knockout installation with the collider 20, the casing plate is detached from the cooled mold, squeezing the coma from the casting of the flask, the casting of the casting and the transfer of the twin flasks to the return transport branch 1 embossed onok. The bottom plate along the transport branch 21 of the fire panels 21, located under the transport branch 19 of the mold cooling, is transmitted to the rotating and extending machine 1 1. Use the proposed line to simplify the design and improve service by eliminating the intersection of FROM different levels of return transport branches wards of plates and accumulation of collected forms due to the fact that these branches are made split in the form of separate segments of transport branches, which converge in one zone, on one level, and in this zone an equipment transfer mechanism is built in, which interacts with the segments of transport branches.
