Description

The invention relates to a foundry and can be used to make castings.

The purpose of the invention is to increase productivity and expand the range of parts produced.

FIG. 1 shows a line for making castings, a plan view; FIG. 2 is a section A-A in FIG. one; in fig. 3 is a view B in FIG. 2; Fig 4 is a sequence diagram of the work area of the knockout.

The mechanized line for the manufacture of castings consists of two independent circuits, which form three main technological areas: the molding section, the mold casting section, and the casting cooling section, the mold knockout section.

Each circuit represents a horizontally closed transport system, which contains an assembly conveyor 1, a conveyor 2 transfer molds to the pouring area, conveyor drives 3, a conveyor 4 transfer filled forms, a conveyor 5 transfer embossed flasks, return conveyor 6 empty supports, return conveyor 7 carts, units 8 for the manufacture of half-molds.

Both contours in the knockout area are combined with a knockout installation 9, which is placed together with the pusher 10 between the contours with the possibility of interaction with moving frames (not shown) of the conveyors 4 and 5 of both contours, and the knockout grid 11

Vibile installation 9 is made in the form of a frame 12 with guides 13 fixed by it, L-shaped copiers 14, stops 15, a pressure mechanism 16, equipped with a table 18 mounted on shock absorbers 17, equipped with vibrators 19 with swinging grip 20, and equipped with mounted movably along the guides 13 from the actuator 21 a movable frame 22 with a stop 23 fixedly mounted on it and swinging the frame 24 with rollers 25 interacting with L-shaped copiers 14 Flasks move along a line on carts

26

Lini works as follows.

The flasks of the top and bottom of the carts 26 mounted on the return pipeline of the flasks of the flasks 6 are transferred to the units for manufacturing

The half-molds are lazy 8. The empty carts 26c of the return conveyor 6, the return conveyor of the carts 7 are transferred behind the assembly conveyor 1, where the rods are installed into the mold, the mold is assembled and the flasks are drawn.

From the assembly conveyor 1, carts 26 with flasks are fed to the conveyor 2 of the mold transfer, from which they are fed to one of the conveyor belts 3, from which the cast forms are currently being delivered to the transfer conveyor of the filled mold 4, while on others can be molded with molten metal.

On storage conveyors x 3, the mold is filled with liquid metal and the castings are cooled in the mold.

Trolleys 25 with filled molds from any / i3 conveyor drives 3, at the operator's choice, are delivered to the movable frame of the conveyor 4 gears of filled molds 4, which feeds them to the knockout installation 9.

The pusher 10 (FIG. 2) transfers the carts 26 with flasks from the movable frame (not shown) of the transfer conveyor of the cast forms A to the empty movable frame (not shown) of the conveyor 5 of the transfer of the stamped flasks, the cart 26 slides over the gripper 20, the shape passes under swing frame 24.

The actuator 21 moves forward, with the frame 24 swinging downward and lowering the arm. and the rollers 25, rolling along the vertical surface of the l-shaped copiers 14, hold the movable frame 22 in place.

After the rollers 25 come off the vertical surfaces of the copiers 14, the movable frame 22 of the swinging frame 24 moves the flasks from the carriage 26 to the stop 18, including one-time vibrators 19 and a breakout mechanism 16. The punching mechanism 16 squeezes out the central part of the mold, and the vibration of the table 18 ensures the cleaning of the walls of the molds from the molding mixture. The molding mixture and casting are fed to the embossing grid 11.

During the reverse movement of the drive 21, the movable frame 22 by the stop 23 moves the empty flasks from the table 18 to the carriage 26, which is held on a movable frame (not shown) of the transfer conveyor of the embossed flasks 5 by the gripper 20, and the rollers 25 rolling along horizontal surfaces of L-shaped copiers 14, keep rocking frame 24 in a lower position. After the movement of the movable frame 22 to the stops 15 and the descent of the rollers 25 from the copiers 14, the swinging frame 24 rises. Movable frames, empty - conveyor 4 transfer of filled forms and filled (with cart 26 and empty flasks) - transfer conveyor flasks 5 exit from the working space of the embossing unit 9, and in their place are movable frames of conveyors 4 and 5 of the second circuit. The conveyor transfer embossed flasks 5 transmits carts 26 with empty flasks on the conveyor 6 empty flasks, which transmits them from the area of embossed Xi to the pouring section.

Installing knockout 9 provides the ability to knock out forms from both contours alternately or knocking out forms from any of the contours.

The use of the invention makes it possible to simultaneously service two circuits for the manufacture of castings, which will increase the productivity of the line as a whole and expand the range of castings, as well as reduce the energy consumption for knockout of castings out of the molds.
