Description

Fig. 2 - a basic kinematic scheme the device.

The device for removing the shielding element has a cutting head which contains two diametrically arranged cutting units 1 and 2 (FIG. 1). Each of the units consists of a rotating cylindrical milling cutter 3, and a with respect to this rolling mill stationary knife 4. Each of the milling cutter 3 rotates counter to the movement of the to be processed line 5, which is the line of movement between the units 1 and 2 (indicated by an arrow A specified) runs. Each pair of milling cutter blades forms a pair of scissors that cut off the shielding element. Between each pair of milling cutter knives there is a gap, the size of which is regulated by a conical sleeve 6.

This regulation ensures the processing of lines of different cross-sections and enables the removal of shields of various densities.

The knives 4 are pressed against the line 5 by a spring 7.

The cylindrical milling cutters 3 receive their rotational movement from an immovable gear wheel 8 (FIG. 2) with the aid of Gears 9, which sit rigidly on shafts 10, and gear drives 11 and 12, of which the gear 11 is on the shaft 10 is attached.

Each of the cutting units 1 and 2 rotates around the line 5 driven by a drive shaft 13, with which the gears 9 are connected by a cross piece i4.

To regulate the length of the end of the line to be processed is a Disk 15 is provided with a stop 16.

The facility works in the following way:

After the diameter of the line to be processed 5 through the conical sleeve 6 and through the stop 16 the required length of the end of this line is set to remove the shield a drive (not shown) is switched on and the line 5 is inserted into the opening of the sleeve 6. the Drive shaft 13 rotates the cross piece 14 together with the gears 9. As a result, the roll the latter on the stationary gear 8, whereby they set the shafts 10 in rotation. The gears 11, which sit on the shafts 10, spin and spin Via the gears 12, the milling cutters 3 counter to the movement of the line 5. When they turn: they tear Milling cutter 3 the shield hoüi that, since they gets between the cutter teeth and the immovable knife 4, is cut off. As a result of Rotation of the cutting units 1 and 2 around the line 5 cuts off the entire shield Circumference.

Claims (1)

Claim: Apparatus of the shield from the ends of wires or cables for removing comprising ^s a rotatable around the line or cable longitudinal axis of the cutting head of two diametrically opposite cutting units arranged transversely to the line or cable longitudinal axis milling cutters between which the cable or the cable is moved through and which are rotatable around their own axes opposite to the movement of the line or cable, and parts of the shielding can be removed by the cutting units, characterized in that the two cutting units (1, 2) each additionally contain a knife (4), each of which has a cutting edge parallel to the axis of the associated cylindrical milling cutter (3) in the direction of movement of the line or cable (5) sliding on its shield and the distance between the cutting edge of the cylindrical milling cutter (3) and the cutting edge of the knife (4) is approximately equal to the wall thickness of the shield . 25th The invention relates to a device for removal the shield from the ends of lines or cables, including one around the line or Cable longitudinal axis rotatable cutting head made of two μ diametrically opposite cutting units with Milling cutters arranged transversely to the line or cable longitudinal axis, between a c "j line or the Cable can be moved through and the opposite to the movement of line or Ka 'el to their respective ^ own axis are rotatable and parts of the shield can be removed by the cutting units. The device can be used in the radio engineering, electronic, and other electro-technical industry as well as in the message generating devices ⁴ⁿ industry, or even at radio and Elektromontage- or repair work. In DE-PS 6 30 212 a Kabelenlisoliermaschine for power and manual operation for the removal of the insulation from single- ^{core cables or from the wires of the 4} ^ multi-core cable is described, in which a fixed cable end rotating, with revolving around its own axis, Radially adjustable knife or milling drums providing support automatically, stepwise advanced in the direction of the cable axis ^ ⁰ . In the case of cables with lead or iron sheath, appropriately designed milling cutters take the place of the knife drums connected to the support. The known device thus has a cutting head. the two diametrically opposite Schneidein- ">having> * directions, / wipe which the line or cable will hill performed and each of said cutting units knife or milling contains. The blades or milling may be opposite to the direction of movement of / lead and machined or ^h" of the cable and at the same time be moved around the wire or cable. Further knives, the cutting edge of which is arranged so as to slide parallel to the axis of the associated milling cutter in the direction of movement of the line on the screen, are not provided in the known device and are obviously not necessary for the purposes indicated there. In US-PS 23 66 271 a device is described which is intended to provide a shielding braid Cut open in the longitudinal direction of the line in order to completely cover it from the line or the cable remove or replace with something else. The device contains a cutting device through which the line is passed through and which contains a side milling cutter, which together with a long, tapered cutting blade, which is advanced into the shielding braid parallel to the LHtung axis, cooperates so that the shielding braid is cut open in the longitudinal direction. The cutting device between the disc milling machine and the cutting blade lies parallel to the axis of the line and thus only allows an axially parallel opening of the shield, while a cutting device arranged transversely thereto is neither provided still makes sense with regard to the task of the known device. The cutting off transverse to the axis of the line or the cable is necessary if you especially the ends of a Wants to free the line or a cable from the shielding. There are also devices for removing the shield from the line ends are known, the one Cutting head in the form of an annular die with the cutting edge along the circumference of the opening in the die and have a tube attachment. The pipe attachment tears open a cone at its end and is used as an overstamp with the help of which the braided shielding is hacked open (see 3U-PS 126 534). This well-known The installation requires that the end of the line has been processed by hand in order to create an annular gap between the wire insulation and the shield for the introduction of the upper punch into the gap. In this case, it is not possible in lines with increased filling density of the shielding braid, one sufficient to obtain a large annular gap. In addition, a set of individual parts must be used for each type of pipe size (Upper punch and die) have. The present invention is based on the object of the device specified at the outset Kind to train so that it can also be used with a shield. which consists of a shielding braid, so that the ends of the lines and cables at any density of shielding or at any Cross-section of a cable can be exposed without their prior preparation. In order to achieve this object, the device of the type specified at the outset is characterized according to the invention characterized in that both cutting units each additionally contain a knife, the cutting edge of which in each case parallel to the axis of the associated milling cutter in the direction of movement of the line or cable whose shield is sliding and the distance between the cutting edge of the cylindrical milling cutter and the Cutting edge of the knife is approximately equal to the wall thickness of the shield. The knives, together with the cylindrical milling cutters, each form a kind of scissors that provide the shield stirs up, whereby the Suhneitlein heal themselves to Turn the line or cable to be processed. In the following, the invention is explained in a detailed description of an exemplary embodiment with reference to the drawings; in the drawings shows F i g. I - the cutting units of the cutting head of the Device in the longitudinal cut;
