Description

(54) DEVICE FOR EROSION TREATMENT

The invention relates to the field of erosion treatment, in particular, to the technology of processing mill rolls, for example, rolls of training machines, and can be successfully applied to the production of cold-rolled sheets for the automotive industry.

Known devices for processing large parts, such as rolls, are complex. When treating the entire surface with multiple electrodes, they require complex use. interelectrode gap control for each electrode.

The purpose of the invention is to increase the stability of the process by creating a dynamic gap between the machined-up part and each electrode, which will eliminate the interelectrode gap controllers.

This is achieved by the fact that each electric tool of the proposed device, included in the autonomous source of the Yitani source, is installed with the possibility of dying on one of the arms of the two shoulders, the second arm of which elastically interacts with the fixed body and is spring-loaded and the spring, the rigidity of which is chosen according to the condition | Providing a given frequency of the oscillating electrode tool. In order to change the frequency of oscillations, the garments are executed by adjusting my rigidity.

FIG. 1 shows the scheme of the proposed device; FIG. 2 - spring-loaded shoulder of the two shoulders; in fig. 3 - installation of a roller electrode.

On the stan 1 of the device, equipped with a bath for the working fluid 2, there are oiors (shown in the drawings) on which the roller 3 is being mounted, driven during rotation.

Along the treated surface with its overlap, there are electrodes-tools 4, each of which are connected to an autonomous power supply circuit.

Each electrode is installed in a ball current w, their supports 5 (see F1 and 3) and one of the shoulders of the two shoulders lever 6, and the second arm of which acts through the rod 7 spring 8 with a force adjustable by a screw 9 (see Fig. 2).

The device works as follows.

The roll 3 to be machined is mounted on supports and is driven into rotation at a speed of 10-50 rev / min. Electrodes-I1-Tools 4, installed in ball bearings 5 on levers 6, are supplied, by means of screws 9, to the surface to be treated.

The electrodes 4 begin to rotate and make forced oscillations under the pressure of mechanical and electrical forces.

The amplitude of the oscillatory movement of the beam electrodes is controlled by changing the stiffness of the spring, pressing the lever with the roller electrodes to the roll.

A wiruga bond allows the size of the displacement of the roller-electrodes to be limited by the action of reactive forces and contributes to the formation of the dynamic gaps necessary for stable formation.

To process the entire working surface, the number of roller electrode tools is chosen such that KCIO does not open the work surface.
