Description

one ;. The invention relates to foundry. The known automatic casting line (ALL) of conveyor design (with a rigid transport link), and the main vehicle of which AE is driven roller conveyor drives (with flexible connection) The main disadvantage of both conveyor and roller table lines is their non-compactness / large raCefits and / or, respectively, the production areas they use.The overall pasMej lines, and first of all its length, are determined in the cooling belt of the filled forms and given by its capacity (mold / mass), the turn determines the technological speed VT (m / min) of moving the molds on the filling and cooling section of the line. The overall size (length) of the flask is q q duration of one cycle, to v - 1o-9 / then v, or the ad- ditional section will be a length is L Thus, the greater the capacity of the line, the higher the technological speed of VY and the longer the cooling section at a given time for the cooling of castings in the B form (toxA const). The disadvantage is aggravated in the lines intended for the production of large-sized and metal-intensive steel casting requiring a long cooling time. However, it is often impossible to increase the length of the cooling section, and, consequently, the length of the entire line by a certain amount, since the foundries are limited in area. We need new compositional and structural solutions for ALL, which would allow, while maintaining and even increasing productivity, while maintaining and reducing the occupied area, increase the cooling time of the filled forms. The line is also known, which includes the molding areas of the upper and lower half-molds with molding units, the half-mold assembly section, with the pairing device, the handicap filling section, and the knockout section with a knockout device

; and steam flasks opok. Offline work, technological areas are interconnected by three branches of transport and cooling drive roller tables. The cooling rolls branch connects the pouring area with the form knocking area. It is a set of two-sided sections of drive roller tables, the upper rusa of which moves the cast forms installed on the base plates, and the bottom rus returns empty base plates 2.

The disadvantages of the line are the non-compactness of large dimensions, and, as a result, the limitation on performance. A further increase in the productivity of the cooling time of the cast forms inevitably entails an increase in the length of the cooling paths (transport), and, in general, the overall dimensions of the line.

The purpose of this invention is to increase the time for cooling the cast forms without increasing the production area.

This goal is achieved in that the line is equipped with a device. For assembling molds with bottom plates in a stack placed at the beginning of the vehicle for cooling behind molded molds, a device for disassembling the stack of molds with bottom plates installed at the end of the vehicle to cool the filled molds, and racks mounted on the bottom surface of the top plates.

FIG. 1 depicts (line-up) of an automatic casting line, plan view; in fig. 2 is a view A in FIG. in fig. 3 - section BB on fit. one.

The automatic casting line consists of five main technological sections: sections 1 and 2 of the molding of the upper and lower half-molds, section 3 of the mold assembly with the pairing device 4, the pouring section with the filling device 5, the driven transport device 1-BSM b, and the tilter 7 of the base plates 8 and knockout area with. a knockout device 9 / spreader 10, tilter 11 of the ward plates 8 and an angled roller table 12. Between them these technological sections are connected by two branches of transport-driven (self-propelled) roller tables 13 and 14 and one branch of the vehicle 15 for cooling the filled-in forms with the bottom plates. Mechanical brushes 16 are mounted on the transport drive roller tables 13 and 14 for cleaning the mode of molds, standard pushers 17, positioners 18 of the molds, mechanism 19 for cutting the mixture inlet, type cutters 20 for fixing the molds

in order to perform the required operations in the scaffolds of the line, etc. Between the casting device 5 and the vehicle 15 for cooling the cast forms with the base plates, the device 21 is integrated for assembling the cast forms with the base plates in a stack. Between the vehicle 15 and the knockout device 9, a device 22 is built in to disassemble the cast forms (one after the other) with the bottom plates. The assembling devices 21 and 22 for disassembling the Sewn forms with the hearth plates are mounted on a branch of a vehicle 15 equipped with a cooling ventilator cover 23 (Fig. 2). The vehicle branch 15 consists of a section of two-sided drive roller tables 24 (Fig. 3) having an upper row of rollers 25 for moving cast forms installed on the base plates 8, and a lower row of rollers 26 for returning from the knockout area to the freeze pouring section ( empty plates.

Arrangements 21 for assembly and 22 for disassembling filled forms are arranged identically and are a lifting and lowering mechanism 27 mounted on four columns — columns 28.

The lifting and lowering mechanism consists of a pneumatic cylinder 29, the rod rail 30 of which is connected to gear 31, which, in turn, meshes with the rails 32. The rails 32, which are the rods of pneumatic cylinders 33, are equipped with chucks 34.

The automatic casting line operates in the following sequence.

In the molding sections of the upper 1 and lower 2 half-molds, the upper and lower half-molds are made, respectively, which are then rotated 180 ° (imprinted to the top) in the turner 18. Next, the upper and lower half-molds move to the assembly section of the molds with the pairing device 4 along the transport drive roller 13 and 14. The upper half-form before the tail with the help of the second tilting device 18 is secondarily turned over by 180 ° (print down), after which it is fed into the mating 4 with the help of a typical pusher 17. The half-forms are assembled into forms. The assembled molds are transported to the casting area with a mouth-hold device 5, where they are pre-installed on the bottom plates 8 and then poured with metal. Flooded molds with subplate plates are moved along the driving transport device 6 to the device 21 for assembling them, i.e. set each to Friend in pairs or more. When the mold enters the SZH device 21: the dark air is supplied to the E upper cavity of the pneumatic cylinder 29 and the rod-rack 30, turning down turns gears 31, which raise the rail 32, while compressed air from the pneumatic cylinder 33 is released into the atmosphere. When lifting the rail 32 by means of the claws 34, the form is raised with a top-shield, which are in a raised position before entering the next form device 21, after which the compressed air is supplied to the pneumatic cylinders 33, and the rails 32 on the hooks 34 lower the first form, which the racks 35 of the bottom plate is mounted on a second (successive) cast form with a bottom plate. A stack of two (or more) each other is installed on the other of the installed cast forms with the hearth plates. At the same time, the compressed air from the pneumatic cylinder 29 is released into the atmosphere, and its rod-rod rises to the upper (initial position). The assembled forms in pairs using a transport device for cooling the cast forms with the bottom plates move under the cooling jacket 23 (Fig. 2) with the supply air. ventilation to the device 22 for disassembling the cast forms with bottoming plates. Moreover, the rate of transfer of the filled-in forms with each of the furnace plates after their assembly decreases as many times as the forms are collected in the stack, and the cooling time increases by the same amount. The device 22, arranged similarly to the device 21, disassembles the piles, for which the upper form with the bottom plate is raised / passed under them, the standing lower form with the bottom plate, and the upper form with the bottom plate is lowered to the space of the transport device. After disassembling, each form with an additional plate is separately transported to the knockout section, where it is stacked with a standard pusher 17 with a bottom plate under the embossing installation 9. After being released, the bottom plate 8 enters the tilter 11, where it is canted, simultaneously lowers and the bottom line of the rollers 26 of the transport device 15 is returned to the portion of the pouring current. With the next stroke, the knockout form 17 is fed under the steamer 10, where the top flask rises and moves along the transport device 15 to the molding station 1. Along the way, the brakes are cleaned with mechanical brushes 16. The bottom of the flask is moved by the angle roll table 12, the transport device 15, and the pusher 17 is moved to the molding section 2 of the bottom flasks. The line cycle is repeated.
