Изобретение относитс к технологическому оборудованию-дл электромонтажных работ, в частности к разделке проводов и кабелей, и может найти применение в судостроительной, электротехнической , радиотехнической и других отрасл х промышленности.The invention relates to manufacturing equipment for electrical installation work, in particular to the cutting of wires and cables, and can be used in the shipbuilding, electrical, radio and other industries.

Известно устройство дл сн ти изол ции и скрутки жил проводов, представл ющее ручной .механизированный . инструмент и состо щее из корпуса, привода и механизма дл надрезани изол ции A device for stripping and twisting the cores of wires is known, which is manual. tool and consisting of a housing, an actuator and a mechanism for cutting the insulation

Недостатком этого устройства вл етс сложность конструкции. Кроме того дл его работы необходимо наличие электрической сети, что существенно сужает область применени данного усТ ррйства.A disadvantage of this device is the design complexity. In addition, for its operation it is necessary to have an electrical network, which significantly narrows the scope of application of this system.

Известно также устройство дл сн ти изол ции с конца провода, содержащее корпус, в направл ющих элементах которого расположен ползун, две пары поворотных рычагов, несущих зажимы и ножи, и привод возвратно-поступательного перемещени рабочих элементов 2 .It is also known a device for removing insulation from the end of the wire, comprising a housing, in the guiding elements of which there is a slide, two pairs of pivoting levers carrying clamps and knives, and a drive for reciprocating movement of the working elements 2.

Однако известное устройство не обеспечивает скрутку жил проводов.However, the known device does not provide stranding of the wires.

что снижает его технологические возможности .which reduces its technological capabilities.

Известен инструмент дл удалени изол ции и скрутки жил проводов, со:держащий корпус, в котором установлены механизм дл надрезки изол ции с зажимными губками и привод. Механизм дл изол ции выполнен в виде цанги, на концах лепестков которой установлены режущие кромки, отогнутые вовнутрь .A known tool for removing the insulation and stranding of the cores of the wires, is: a holding body, in which an insulation notch with clamping jaws and a drive are installed. The insulation mechanism is made in the form of a collet, at the ends of the petals of which cutting edges are bent inward.

Однако в этом .устройстве отсутствует элементу дл . удержани провода от продольного перемещени и поворота , а поскольку возникающие усили довольно значительны, то требуетс дополнительное приспособление дл удержани . Кроме того, само устройство перед использованием необходимо закрепл ть на кронштейне, что снижает его производительность.However, in this device there is no dl element. keeping the wire from moving longitudinally and turning, and since the forces generated are quite significant, an additional fixture device is required. In addition, the device itself must be fixed to the bracket before use, which reduces its performance.

Цель изобретени - повышение производительности и уменьшение усили резани .The purpose of the invention is to increase productivity and reduce cutting effort.

Claims

The post, the aim of the object is achieved by the fact that the device for stripping the wires and stranding the cores contains a mechanism for clamping the wire, made in the form of a collet, equipped with a drive for its reciprocating movement. To reduce the cutting force in the collet of the mechanism for cutting the insulation, a cylindrical hole is formed to form additional cutting edges, the axis of which is perpendicular to the axis of the collet and intersects it. FIG. 1 shows the device, a common fork; Fig. 2 shows a cutting collet section; FIG. 3 is a view A of FIG. 2; FIG. 4 - clamping collet, slit. The device consists of a housing 1, a mechanism for cutting insulation, made in the form of a cutting collet 2, a mechanism for clamping a wire, made in the form of a clamping collet 3, and a drive. The drive includes a handle 4, a toothed sector 5, and a movable part representing the cup; 6 with a portion of the toothed rack 7. The underside of the drive is fastened to the clamp collet with screws 8 and, compressing the spring 9, is displaced relative to the housing, while the pin 10 ensures the straightness of movement. Cutting the collet is fastened to the housing using a ball bearing 11 and can only rotate relative to the housing. To ensure this rotation in the cup, a guide pin 12 is installed, the end of which enters the screw groove 13 made in the shank of the cutting collet. To cut the insulation, the cutting collet has the main cutting edges 14, and the clamping surface 15 serves to clamp the cut off part of The cylindrical hole 16, made in the cutting collet, forms additional cutting edges 18 with the front end surface 17 and provides the necessary sharpness of the cutting edges in the region of the slits 19 and leads to a significant decrease in the insulation notch and improve the quality of work. The hole axis is perpendicular to the axis of the collet and intersects it. The reverse cone 20 serves to compress the cutting collet, and the hole 21 to remove the cut off portion of the insulation to the outside. In order to compress the clamping collet, there are straight 22 and 23 inverse cones with a groove 24, and a notched jaw 25 ensure reliable wire retention during the operation. In the initial position, both collets are in the expanded state. The device operates as follows, a wire (or cable conductor) is inserted into the holes of the collets to the required depth, and then press the handle 4 until it stops. As a result, the toothed sector 5 is rotated and. Through the toothed rack 7, the movable part of the drive with the clamp collet 3 is moved. At the same time, the cup 6 is thrust on the reverse cone 20, the cutting collet. The ha 2 is compressed and cutting edges 14 and 18 are notched, and the clamping surface 15 clamps the cut part of the insulation. After that, the clamping collet 3 is compressed (as a result, its straight cone 22 is pushed into the conical bore of the housing 1) and the jaws 25 clamp the wire tightly. With its further movement, the clamping collet 3, remaining in the compressed state, pulls the wire out of the cutting collet 2, while the notched jaw 25 ensures reliable retention of the wire. At this time, the cutting collet 2 is also in a compressed state and rotates relative to the body (due to the fact that the guide pin 12, moving in a straight line, hits the helical groove 13), thereby tightening the cut off part of the insulation and twisting it wire strands. At the end of the movement, the clamping collet 3, due to the presence of the groove 24, expands and releases the wire. Do not release the handle 4, the wire will remove the device lia. Then the handle is released. Under the action of the spring 9, the movable part of the wire goes back. In this case, the clamping collet 3, moving in a straight line, is first compressed (due to the presence of the inverse cone 23), and then opened, and the cutting collet 2, having made a turn, expanded and released the cut part of the insulation. The device returns to its original position. The cut-off portion of the insulation through the holes 21 in the cutting collet 2 is pulled out. Thus, using the proposed device, without the use of additional devices and devices, one-click hand removal of the insulation with simultaneous twisting of the core. Claim 1.
