Abstract

The invention relates to process equipment for the preparation of electrical wires for installation and can be used in the electrical, electronic and other industries. The purpose of the invention is to simplify the design. To set the cutting edge of the knife 10 for cutting the insulation, unseat the ring, unscrew the screw 8. In the resulting gap between the surfaces 3 and 4, put the insulation sample 19 and compress the ring with the screw 8. When the compression ring is pressed, the hydrogen only touches the edge knife blades and insulation can not be cut. With the help of a sample of the insulation, the half-prisms for the wire are fixed in the divorced position, at which the insulation is cut by the thickness of the insulation without damaging the core. After securing the insulation sample, install a wire on the bevel surface and press it with a clamp 8. Turning the device around the wire, the insulation is cut. 7 il.

Description

The invention relates to process equipment for the preparation of electrical wires for installation and can be used in the electrical, electronic and other industries.

The aim of the invention is to simplify the design.

FIG. 1 shows the device, a general view; in fig. 2 - the same, top view; in fig. 3 - the position of the knife in the segment groove; in fig. 4 is a section A-A in FIG. one; in fig. 5 is a section BB in FIG. one; in fig. 6 - the mutual position of the closed prisms, knife and wire to configure the device; in fig. 7 - the same, after setting up the device.

The device includes a housing 1, made in the form of a flat ring. The ring has in one place a radial section along the axis with the formation of the slit 2. The width of the slit 2 of the slit is more than the thickness of the insulation being removed (Fig. 7).

On the surface 3 and 4 of the slit on the outer side of the ring, bevels 5 and 6 (Fig. 7) are formed, forming a lodgment in the form of two half-glasses for accommodating the wire 7.

Surfaces 3 and 4 may come into contact with each other when the body is compressed by a screw 8 located in openings made in the body.

A slot groove 9 located symmetrically to the slot 2 is made across the slit 2 on the outer side of the ring to place the knife 10 in it. The knife 10 is secured in the housing with screw P. To ensure a constant position of the blade 12 of the knife 10 relative to the base 13 of the base 9, the knife is placed in the holder 14 and fixed in it with screws 5.

The position of the knife in the cage is determined by the stops 16 (Figs. 3 and 5), to which the knife is pressed by the blade 12, thereby ensuring the constancy of the size H from the edge of the knife blade to the base 17 of the holder 14 after the non-curvaceous knife (Fig. 5).

The groove 9 is made in the housing so that when the ring is compressed, the wire 7 laid on the surface of the bevels 5 and 6 half-prism only touches the blade of the knife (Fig. 6), which in this case rests on the surface 17 of the sleeve on the surface 13 of the groove.

A spring clamp 18 is fixed on the housing to hold the wire 7 in half-prisms.

Position 19 denotes an insulation sample, removed from the wire to be treated as a longitudinal strip 1.5–2 mm wide and 4–6 mm long.

The device is designed to remove the insulation from the wire of sections 4; 6; And) brand BIF.

The device works as follows.

The wire 7, laid on the half-prisms, with a compressed ring, only touches the blade-blade edge with insulation 20, and the insulation cannot be cut (Fig. 6).

To set the cutting edge of the knife (Fig. 7), the ring is uncoupled to cut the insulation, unscrewing the screw 8 so that a gap 2 is formed between surfaces 3 and 4, sufficient to accommodate the insulation sample 19 that is previously separated from the wire to be processed.

A sample 19 of the insulation is placed in the gap between the end surfaces and the ring is compressed with a screw 8. After that, the insulation sample is firmly held by the compressed ring.

A sample of the insulation is installed in slot 2 on both sides of the ring planes up to the stop on the side surface of the knife (Fig. 4) or on one side of the n; 1-plane of the ring (Fig. 2).

Using a sample of insulation, a half-prism for the wire is fixed in a diluted position, at which the insulation is cut to its thickness without damaging the core.

The depth of the insulation can be set by changing the angle of the bevels.

After the insulation of the sample has been bonded, a wire is placed on the surface of the bevels 5 and 6 half-eyed and the wire is pressed by the clamp 18.

Turn the device around the axis of the wire. In three or four turns (depending on the force of the spring clamp), the insulation is incised to its full depth without cutting the core, since when the G0o approaches, the impurity in example 8 of the insulation sample is somewhat deformed and thus the wire approaches the knife not completely ; 1 insulation;
