Abstract
An installation for electrohydroblasting of castings comprises a base, a bath placed on said base, a mechanism for feeding castings into the bath, an electrode, and a mechanism for introducting the electrode into the bath and a pulse current generator coupled electrically to the electrode. An insulated casing is mounted on the base over the bath. The insulated casing is built of a latticed framework whose openings are covered with slabs, each being formed with two metallic boxes, one inside the other, so that the ends of one box face a bottom of the other, box with a space formed between the bottoms, intended for a vibration-absorbing material to be fed thereto and with the metallic boxes being grounded.
Claims8
In an improved installation for electrohydroblasting of castings having a base;
- a bath mounted on said base;
- a mechanism for feeding castings into the bath including a lift platform located near the bath;
- an electrode located over said bath;
- a mechanism mounted on a trestle for transporting and introducing said electrode into said bath;
- and a pulse current generator coupled electrically with said electrode;
- said improvement comprising:
- a noise-insulated casing having a substantially closed profile, including a space lattice framework having rows of openings, mounted on said base over said bath and enclosing the bath, the trestle and electrode, and the mechanisms for feeding castings and for transporting and introducing the electrode into the bath;
- a plurality of grounded slabs each formed with two metallic boxes, each having a bottom and sides, inserted one into another in a manner that the ends of the sides of one box face a bottom of the other box, with the space between the bottoms filled with a vibration-absorbing material, and being capable of guarding service personnel against a pulse magnetic field and of withstanding considerable dynamic alternating loads, and the openings in said space lattice framework receiving and retaining in place said slabs;
- whereby both the harmful effects of vibration noise and the pulse magnetic field are substantially avoided with the use of said framework and said grounded slabs.
