(54) MECHANISM FOR OPENING THE STOPPER OF THE FILLING DEVICE FOR AUTOCLAIN UNITS

I

The invention relates to metallurgy and may be used in autoclaves in the dp foundry.

According to the main author. ev No. 394160, there is a known mechanism for opening a stopper of a filling device of an autoclave unit, comprising a drive for gripping and lifting a stopper including a hydraulic cylinder, the stem of which enters the inside of the autoclave through a seal and interlocks with the shank of the stopper with a fork attached to the axis of the Ul Ul stem.

In the known mechanism for holding the set of the casting device in place when the stopper is lifted, especially when it is frozen, special clamping devices are provided, which must be fixed every time the casting device is installed in the ankloklav. When the crucible is removed from the neck of the autoclave for the next pouring of metal, the clamping devices are detached, which creates convenience in the operation of the autoclave unit.

The aim of the invention is to ensure reliable retention of the set of the filling device when lifting the 1st stopper and eliminating the need to use the holding system of the filling device of the special right devices.

This is achieved by the fact that the fork-10 grip is made with the guides of the eyes, in which the spring-loaded pins are installed ynopibie.

In figr. 1 shows the mechanism shown in FIG. 2 is a view A of FIG. one;

15 per f. 3 - mechanism with an open stand; in fig. 4 - fork-grip.

The opening mechanism of the stopper of the autoclaving unit installation is mounted on the lid of the autoclave 1 to so20 from a hydraulic rod 2 with a rod 3, which is installed in glass 4 with a spring 5 placed in the housing 6, and the hook-grip 7 of the hydraulic capsule 2. In the fork 7, they are made guide pins 8, in which thrust pins 9 are installed with springs H, which are held by a ring .11.

The device works as follows.

When the mastata is fed into the lower cavity of the padrotsilindra 2, the rod 3, moving up, turns the fork-claw 7 around the axis 12 to the vertical operating position I until the shoulders of the claws 7 fall into the bottom of the body 6, while the spring 5 holds the cup 4 in the lower position and the thrust the pins 9 are between the flange 13 and the fixed body 6,

With further stroke 3 up. fork-grip 7 grabs the tail with a nut 14 of the stopper 15 of the pick-up device and lifts the stopper. The cup 4, together with the fork 7, compresses the spring 5. The pins 9, resting against the body of the flange 13 of the filling device, make the set of the filling device in place.

During the return stroke of the rod 3, the yoke fork 7 is lowered along with the cup 4 until the latter stops against the stationary Kopetiyca 6 collar, after which the yoke fork 7 is turned together with the thrust pins 9 to the horizontal initial position H

The use of the mechanism will allow zapivku forms of liquid metal in the autoclave otseshovke without the use of special clamping devices to hold the set of the filling device in place during freezing

the tip of the stopper to the drain sleeve.

The use of such a mechanism is necessary because the set of the casting device is interchangeable, since after each discharge of the metal this complex

must be removed from the neck of the autoclave to fill in the next batch of liquid metal, and the use of pressure devices complicates the operation of the autoclave plants.
