SU768537A1 - Automated line for producing castings - Google Patents

Description

An increase in the calcination temperature on the existing lines from 950 to 1200 ° C leads to a sharp reduction in the service life of the flasks, furnaces and other equipment, as well as worsening the conditions for maintenance personnel, especially in the process of filling metal into molds.

The purpose of the invention is to improve the quality of castings, reducing the calcining cycle and the consumption of heat-resistant steel.

The goal is achieved by the fact that, in a well-known mechanized production line, having a quenching furnace with a slotted channel in the hearth and a cooling chamber, located above the transport routes, on which there are carts with pallets moved by movement mechanisms, along the process, it is equipped with auto operators, which are installed between the prokalochny furnace and the cooling chamber, above the cooling chamber in the installation area of the cassettes. The line is also equipped with removable cassettes and shells mounted on pallets of trucks.

FIG. 1 shows the proposed line; in fig. 2 - view A of FIG. one.

The line has a quenching furnace 1 through passage, a cooling chamber 2 transporting paths 3 for carriages 4 with pallets 5, a cassette 6 and a skin 7, mechanisms 8-1 i, carts moving, auto operators 12-15 moving at their navels 16 and 17, a mechanism 18 for removing the filler from the pallets, mechanisms 19 and 20 for shaping, vibrators 21, mechanisms for transporting the filler 22 and 23, a tank 24 with running water, a reservoir 25 of shells, a pusher 26 of shells.

Lini works as follows.

On, the pallet 5 of the carriage 4 by the auto-operator 15 installs the cassette 6. At the bottom of the cassette, a layer of filler is poured from the molding mechanism 20. On the layer of filler install the blocks of shells, move the cart mechanism 11 by one step. Try operation on the following carts. When the carts 4 arrive at the loading position in the tempering furnace 1, the movement mechanism 8 is activated and the trolley is placed in the furnace. After calcining the blocks for 40 minutes, the first carriage with the blocks is pushed out of the furnace by the mechanism 8 to the position of the shell installation. The operator 12 sets the shell on the pallet, closes the Grid funnels of the blocks with the caps and moves the cart to the molding position. In the process of forming, including vibrate 6 {) s 21. A cart with molded blocks by mechanism 8 transmits & M PICILE yaylevki. After the blocks have been poured, the trolley cyclists are moved by mechanisms 9 and 10 until the shell is removed. The operator 13 remove the shell and transmit it to the drive 25, push the pusher 26 one step. On the position

unloading by the operator 14 remove the cassette 6 with castings and lower it into the tank 24 with running water, pull it out of the water and transfer it to the transport device (not shown) for delivery

castings for the operation of separation of ceramics. The remaining filler on the pallet, after removing the cassette with castings, is removed by the mechanism 18 and the trolley is transferred to the installation position of the cassettes. Further, all operations are repeated.

The line can be operated automatically and controlled manually from each position. Application of the proposed line for

the production of castings in the produced models reduces the scrap of ceramic molds by destroying M from 5 to 2%, reduces the marriage of castings by a factor of 2-3 and saves heat-resistant steel by 50%.
