Изобретение относитс к обработк металлов давлением, в частности к оборудованию дл образовани колец на концах электрических проводов, проволоки, используемой при сборке электрических схем,- силовых шкафов, осветительных щитов.The invention relates to the processing of metals by pressure, in particular, to equipment for forming rings at the ends of electrical wires, wires used in assembling electrical circuits, power cabinets, lighting panels.

Известно устройство дл гибки колец на концах проволоки, содержащее смонтированные на станине с направл ющими механизм подачи, механизм предварительной гибки и механизм окончательной гибки, имеющий формующую матрицу и оправку 1,A device for bending rings at the ends of the wire is known, comprising mounted on a frame with guiding feed mechanism, preliminary bending mechanism and final bending mechanism, having a forming matrix and a mandrel 1,

Недостаток, известного устройства состоит в том, что его технологические возможности ограничены.The disadvantage of the known device is that its technological capabilities are limited.

Цель изобретени - расширение технологических возможностей устрой ства.The purpose of the invention is to expand the technological capabilities of the device.

Указанна цель достигаетс тем, что известное устройство дл гибки колец на концах проволоки, .содержащее .смонтированные на станине с направл ющими механизм подачи, механизм предварительной гибки и механизм окончательной гибки, имеющий формующую матрицу и оправку, снабжено размещенным в направл ющих станины ползунрм и смонтированнымиThis goal is achieved by the fact that the known device for bending the rings at the ends of the wire, which are mounted on the frame with guides the feeding mechanism, the preliminary bending mechanism and the final bending mechanism, having a forming matrix and a mandrel, is equipped with a slide block and mounted in the guide frame.

на станине опорными роликами, а механизм предварительной гибки выполнен в виде шарнирно установленной на станине с возможностью взаимодействи с ползуном матрицы с несколькими гибочными ручь ми и с упорным выступом дл конца проволоки, причем механизм окончательной гибки состоит из копира и соединенной с ползуном посредством ласточкина хвоста фигурной матрицы с нес-. колькими гибочными ручь ми и со скосами, контактирующими с опорными роликами и с копиром, размещенным на станине между ее направл ющими.the support rollers on the frame, and the pre-bending mechanism is made in the form of a matrix hingedly mounted on the frame that can interact with a slider with several bending strands and with an abutting protrusion for the end of the wire; matrices with carry- with multiple bending creeks and with bevels in contact with the support rollers and with a cam placed on the frame between its guides.

Rings.

Claims

The device consists of a stepped mandrel i, a pre-bending mechanism with a matrix 2, I have. thrust protrusion 3 for wire 4 and bending streams 5, pivot on the 6 axis of the bed 7 with guides, slide plates 8 and supporting rollers 9. The mechanism, the final bending, has a copier 10, figured matrix 11 s. several bending creeks 12, a stopper 13 with windows 14, and an emphasis 15. Bevel 16 and a dovetail-type fastening 17 are made on the matrix 11. The device operates as follows. The stripped end of the wire or wire 4 is inserted into the window 14 of the limiter 13 of the corresponding section and , touching the stepped mandrel 1, is fed to the stop protrusion 3 of the left forming matrix 2 rotating on the axis 6. Then the drive mechanism is activated, which actuate the slider 8 by means of a lever (not shown). Moving along the guides of the bed 7, the slider 8 acts on the left formative M / W 2, which, in turn, moving around the axis b, affects the wire 4, forms a half ring. The stop 15 prevents the wire 4 from moving. Next, the slider 8 drives the actual figure-shaped forming matrix 11, Last, moving along the copy 10, the swallow-tail 17 and the supporting angle 9, completes the ring formation. After that, the slider 8 ,. the right mold die 11 and the left die die .2 return to the initial position, the drive is turned off, and the device is ready for recycle, and at the intermediate stage of the return mandrel 1 goes into the body ring formation mechanism, which makes it easy to remove the finished product. The proposed device allows you to expand the range of sections, processed electrical Wires, to obtain a ring at the ends of the wires of the correct form, ensuring reliable electrical contact during installation. Apparatus of the Invention A device for bending rings at the ends of a wire, comprising mounted on a bed with guiding feed mechanism, preliminary bending mechanism and final bending mechanism, having a forming matrix and a mandrel, characterized in that, in order to expand technological capabilities, it is provided with base slider and mounted on the frame supporting rollers, and the pre-bending mechanism is made in the form of a hinged mounted on the frame with the ability to interact with the floor a single matrix with several bending strands and with an abutting protrusion for the end of the wire; the final bending mechanism consists of a copier and a dovetail figured matrix connected to the slide with several bending strands and with bevels in contact with the support rollers and with a copier placed on frame between its guides.
