Description

srig.1

The invention relates to foundry and can be used in automatic molding lines.

The purpose of the invention is the improvement of operating conditions, as well as the expansion of technological capabilities.

In Fig. 1, a pre, a paged tilter is shown; figure 2 is broken LA-figure 1; on fig.Z - tilter, top view.

The tilter contains support 1 installed on a typical NATURAL roller table 2 of the automatic molding line (shown ycJtoBHo), 3-turn drive with leading gear 4 and intermediate gear 5 gears, 6-lift drive with rod, connected with flexible elements 7 with frame 8. On the gearbox 9 of the gearbox 10 are fixed a swivel grip 11 flasks (half-molds), a clamp 12 to prevent products from falling, a rod 13 connecting the clips with their actuators 14 and 15, pneumatic or hydraulic shock absorbers 16. Each frame is installed with the possibility of rotation around the axis 17, i ra which the gear 18 is installed coaxially with it. The locking pins 12 in the form of pins pass through the grippers 11 and are installed on the same axis with them.

To use the tilter at the same time as a transfer unit, in order to combine the functions, its support 1 is mounted on rollers J9 and connected to a movement actuator 20.

Tilter works as follows.

The half-form (support, any product) along a typical drive roller table 2 (or a workshop conveyor) is moved into the zone of the turner and enters its grips P. The pneumatic actuator 15 turns on clamps 2 passing through clamps 11 fixed coaxially with clamps. When turned on, latches are inserted into holes made in flasks. After that, the lifting drive 6 lifts the flask by turning the frame 8 around the axis 17 using flexible elements 7. Chain, cable, etc. can be used as flexible elements. It is possible to connect the lifting drive with the frame directly through a hinged connection (with a vertical drive arrangement).

After turning the frames 8 and the turning jaws 1i into the upper (or intermediate) position, the actuator 3 turns 3, which through the gears 4,5,18 and 21 and the grippers 11 rotates the product 180. After that, the actuator 6 lowers the flask on the live rolls 2. At the end Lowering, pneumatic api hydraulic shock absorbers 16 are activated, ensuring smoothness at the end of the path. Perekantovanna flask on the roller conveyor 2 out of the zone tilt, and the next comes in its place. The cycle is repeated.

On automatic molding lines, it is often necessary not only to recast the flasks, but also to rearrange them to another position, such as an assembly, a conveyor, etc. Dp of this install special skidders with grippers, lifting (lowering) and displacement drives. In order to combine the functions of turning and re-positioning the products, the proposed tilter has rollers 19, on which the support 1 of the turn-over device is connected to the movement drive 20. With this solution, re-branded product 22 can be moved and moved to another position without installing additional mechanisms.

The proposed tilter with the described mutual arrangement of components and parts allows to achieve the following advantages:

to improve the conditions of operation and the quality of the casting due to the exclusion of half-molds for the litters When turning, the molding mixture does not fall on the rotating parts of the turning device and, accordingly, on the half-mold;

to improve the layout and binding of the tilting device anywhere without creating special additional devices, to improve the cleaning of spillage on the line;

to simplify the structure, eliminating special mechanisms (pusher, drive roller) for supplying products to the re-shaping zone, and thereby improve its maintenance, increase reliability, reduce labor intensity in manufacturing, etc.

combine the functions of the tilter with the functions of other elevators, excluding the latter from the complex of equipment of the automatic molding line.
