    A device is disclosed for breaking off the wire-like or strip-like consumed electrode in electro-erosion machines for the processing of workpieces. At a delivery side of the device the consumed electrode is moved by feed rollers into a gap between the surface of an anvil and a multi-edge bit which rotates in front of this surface and is driven by the feed rollers. The rotating bit edges groove the electrode on the anvil surface to cut it into small pieces which fall into a collector container.

    (54) DEVICE FOR PART SEPARATION The invention relates to the processing of metals by pressure, in particular for cutting wire and tape materials, and can be used in industry for cutting waste electrodes of electrical erosion machines. A device for dividing a lengthy material is known, comprising a housing, feed rollers associated with a rotational drive, and a separation assembly in the form of a support and a multi facet tool rotatably mounted and cooperating with support tl. The drawback of the device is that the support is rigid and when the multifaceted tool interacts with it, the tool quickly blunt and the reliability of the device decreases. The absence of a guide also reduces the reliability of the device. The purpose of the invention is to increase the reliability of the device and the tool life. To achieve this goal, a device for dividing a lengthy material into parts, comprising a housing, feed rollers associated with a drive, and a separation unit in a LONG-DIMENSIONAL MATERIAL in the form of a support and a multifaceted tool installed with the possibility of rotation and interaction with the support, is provided with a guide placed between the feed rollers and the separation unit, whose support is made in the form of a tilting plate and is spring-loaded relative to the housing, and the tool is connected by means of an intermediate gear to the feed rollers. Intermediate transmission can be made up. FIG. 1 shows the device, a general view; in fig. 2-4 are the same as material separation steps. The device comprises a housing 1 with inlet 2 and outlet 3 holes and feed rollers 4 and 5 disposed therein, a separation assembly and a guide 6 rigidly connected with housing 1 and located between the delivery rollers and the separation assembly. The knot of the section neither contains a support 7 in the form of a plate mounted on an axis 8 with the possibility of swinging and spring 9 relative to the housing 1 and a multi-faceted tool 10 mounted for rotation on the shaft 11. The feed rollers 4 and 5 are spring loaded
    relative to each other and associated with a rotational drive (not shown. The working surface of the rollers may have a notch to prevent slippage of the feed material (electrode 12. In the preferred embodiment, the feed rollers 4 and 5 have a rotational speed greater than the feed rate of electrode 12, for example by 5%, as a result, the supplied electrode is always chickpeas, which prevents it from being entangled in the input wiring 13, Plate 7 is made with a bevel 14 to better guide the electrode. A multi-edged tool 10 is associated with feed rollers 4 and 5 in An intermediate gear (not shown). The intermediate gear is increased. The tool is faster than the rollers, for example by 5%.
    The device works as follows.
    The electrostatically charged copper electrode 12 used in the erosion process is fed by the feed rollers 4 and 5 of Fig. 1. In front of the rotating tool 10 and under the support 7 there is a guide 6, which deflects the electrode towards the surface 15 of the support 7 (Fig. 2). By means of the edges of the tool 10, the electrode 12 is pressed against the surface 15 of the support, and a notch is made on the electrode (Fig. 3), i.e. at the place of the notch, the copper electrode becomes thinner in its cross section. Due to the fact that the support is spring-loaded in the housing, the tool 10 does not completely separate the piece 16, does not completely push the notch.
