FIG. 2

The invention relates to a foundry, in particular, to a device for cleaning ceramics from castings obtained by the method of casting on melted and gasified models.

The aim of the invention is to improve working conditions and increase productivity.

FIG. 1 shows the installation section; in fig. 2 - the same plan view.

The installation contains a base 1 with installed vertical columns 2 and a rotary column 3 fixed with help of bearing 4 and subframe 5. On columns 2 an anvil 6 is installed and directed ush, and yoke 7 on which is fixed with the possibility of vertical mounting mesh, vibrotool 8, associated with the pneumatic cylinder 9. On the column 3 a rotating wall 10 is installed, on which, in turn, are located the directional rolling pins 11. On the rolling pins 11 by means of springs 12 are installed the clamps 13. The number of grips 13 on each side wall 10 is equal to h vibrotool tools 8.

Outside, the installation is sheathed by a sound-insulating casing 14, in one of the walls of which a door 15 is located. At the vertical ends of the wall 10, seals 16 are installed, adjacent to the casing 14 in extreme positions, one of the seals 16 adjoining the casing 14 with the outer, and the other, on the opposite end of the turning wall 10, from the inside.

At the upper end of the column 3, an actuator 17 for rotating the wall 10 is mounted, for example a rack and pinion mechanism with a pneumatic cylinder 18.

The installation works in the following way.

A manipulator (not shown) in the grips 13, located on the outer side of the pivot wall 10, are installed under the processing blocks of castings, after which the installation is put into operation.

In this case, the pivot wall 10 is rotated by 180 ° until the seals 16 touch the casing 14. Moreover, the cushion that adjoins the casing 14 on the inner side abuts on the opposite side of the opening from the outside and vice versa.

After completing the rotation of the wall 10, the axes of the grippers 13 and, accordingly, the axis of the casting blocks installed therein

with the axes of the vibrotools 8. The pneumatic cylinders 9 are automatically given a command to press the vibrotools 8 against the casting blocks. After the vibrotool 8 is in contact with the casting unit, the corresponding gripper 13 under the force of the pneumatic cylinder 9 is lowered on the rolling pins 11 until the central one reaches the anvil 6 to the casting unit, after which the vibrating tool 8 is automatically turned on. The processing of the blocks begins.

During the processing of the blocks, the manipulator replaces the casting blocks on the grippers 13, which are at this time from the outer side 5 of the rotary wall 10. The control system provides for blocking, which excludes the inclusion of the vibrotool 8 if the casting unit is not installed in the corresponding gripper.

After completion of processing of blocks from 0 holes, each pneumatic cylinder 9 retracts the corresponding vibrotool 8 to the initial position.

The grips 13 with the casting blocks under the action of the springs 12 are returned to the initial 5 position, the wall 10 is rotated, after which the cycle is repeated.

During the processing of the blocks, the soundproofing casing 14 and the pivot wall 10 form an airtight working chamber. Door 15 opens only during repair.

The use of the proposed plant allows for increased productivity and improved working conditions.

Claims (1)

Invention Formula An apparatus for vibratory cleaning of castings, predominantly poured into blocks, containing a control system, an anvil, columns and vibrotools enclosed in a soundproof casing, as well as a window for loading and unloading castings, overlapped by a door installed on the casing, so as to improve working conditions and increasing productivity, it is equipped with pair claws of 5 casting blocks fixed on both sides of the door, while the door can be rotated around the vertical axis of symmetry, and the number of pairs per grip equal to the number of vibrotools.
