Изобретение относитс к технике р азделени проката и слитков на заготовки, в част ности к устройствам дл разделени стальньд слитков на заготовки клином на соос- ной опоре.The invention relates to the technique of separating rolled products and ingots into blanks, in particular, to devices for separating steel ingots into blanks with a wedge on a coaxial support.

Известно устрюйство дл ломки слитков, проката на заготовки, содержащее клин в ваде треугольной пркэмы, жестко закрепленной в траверсе, и соосную опору длч заготовок |l .A device is known for breaking ingots, rolling on blanks, containing a wedge in a triangular wedge, rigidly fixed in the traverse, and a coaxial support for blanks | l.

Известное устройство работает следующим образом.Надрезанный слиток подаетс толкателем между клином и соосной опорой. Под действием привода клин внедр етс в надрез между заготовками и шейка ломаетс . В этом устройстве клин внедр етс не по оси надреза, а несколько в стороне от нее. Это происходит потому, что точно совместить ось надреза с осью клина при подаче слитка толкателем практически невозможно. Вследсгвие этого клин под действием привода, попада -в не- соосный надрез, перекашиваетс , возникает изгибающий момент между слитком и клином , который быстро выходит из стро . При The known device operates as follows. The cut ingot is fed by a pusher between the wedge and the coaxial support. Under the action of the drive, the wedge is inserted into the cut between the workpieces and the neck breaks. In this device, a wedge is inserted not along the notch axis, but somewhat away from it. This is because it is almost impossible to precisely align the notch axis with the axis of the wedge when the ingot is fed by the pusher. Following this, the wedge under the action of a drive, falls into an unaxially incision, warps, and a bending moment arises between the ingot and the wedge, which quickly fails. With

внедрении клина в Надрезы слитков егс) плоскости все врем контактируют со слитком в одних точках, из-за чего клин быст;х изтшиваетс и выходит иа стро . Ввиду ось клина не совпадает при разламывании слитка с осью надреза, силы, раз- рушаю1цие шейку, распредел ютс в слитке несимметрично. Вследствие этого дл раз|ламывани слитков на заготовки требуютс большие усили ломки.the introduction of the wedge into the cuts of the ingots of the ECG) plane all the time are in contact with the ingot at one point, because of which the wedge is fast and is worn out and goes out of the line. Due to the axis of the wedge does not coincide when the ingot is fractured with the notch axis, the forces breaking the neck are distributed asymmetrically in the ingot. As a result, large breaking forces are required to break ingots into billets.

Цель изобретени - увеличить срок служ |бы устройства и повысить его производительность .The purpose of the invention is to increase the service life of the device and improve its performance.

Это достигаетс тем, что клин выполнен в виде подпружиненного с торцов и свободно сид щего на оси диска с клиновой заточкой , на наружном диаметре которого нанесо ны углублени , контактирующие с собачкой храпового механизма. Устройство снабжено масленкой, выполненной в виде трубы ип эластичного; материала, котсцюй повтор ет форму клина.This is achieved by the fact that the wedge is made in the form of a disk with a wedge grinding surface that is spring-loaded from the ends and freely seated on the axis; the outer diameter of the disc has recesses in contact with the ratchet pawl. The device is equipped with an oiler, made in the form of a pipe type of elastic; material that coats the shape of a wedge.

Claims

Fig, 1 shows the iipojuiaiflpt.-c.p device, general view; FIG. 2 l. And p, i: tpt: along A-A in FIG. one; on . 3 shows a device for breaking, top view. The device for breaking the car into zgasti consists of a disc bar 1 with depressions 2, a disk wedge axis 3, a cross member 4 with columns 5, pushers 6, springs 7, a coaxial bearing 8, a pawl 9. In the device for breaking there is an ingot 1O with notches 11 and necks 12. The disc wedge 1 is lubricated with the help of an oil can 13 with a patrol 14 fixed in a shunt 11 15. The device operates as follows. After the ingot 10 is fed with a notch 11 between the disk wedge 1 and the coaxial bearing 8, under the action of a drive, a discrete one; a wedge | is inserted between the stumps and the neck 12 is broken. If the notch axis does not coincide with the .. axis of the clutch, disk wedge due to flatness. the gay wedge pad will shift j along axis 3 and take j position along the notch axis. Under the action of the disk wedge and the pusher 6, one (of the two springs 7 is compressed. After the ingot is broken under the action of the compressed spring, the disk wedge will take up its original position. The dog 9 is pivotally attached to the fixed point of the ingot body with one end and t the sheet lies on the wedge sharpening of the disc wedge 1. When the ingot is broken, the disc | Еннн moves towards the coaxial bearing, the dog lowers (the position is shown by a dotted line) When the disk wedge returns to its original position, the dog enters with the recess 2 and the disk wedge scrolls. During the scrolling, the disk wedge is simultaneously lubricated with a grease coming from the butterdish 13, which is described on it by a spout 14 made of elastic material and freely mixed with it along the guides 15. The presence of the device of a disk wedge with I groove on the wedge sharpening, the axis of the turn and the pawl ensures the scrolling of the disk wedge for each fracture; Goes to uniform wear. The presence of an oiler with an elastic P4trzbkom wedge under the wedge and guides ensures a constant lubricant when scrolling the wedge. Combination; a disk wedge, axis of rotation, pushers and springs ensures the centering of the disk wedge along the notch axis and the symmetrical distribution of forces arising from the fracture of the necks of the ingot. Apparatus of the Invention A device for breaking a rolled stock into workpieces containing a wedge fixed in a cross bar of a press and coaxially supported, characterized in that, in order to increase the service life and increase the productivity of the device, the wedge is made in the form of a spring loaded at its ends and free on axis disk with a wedge sharpening, on the outer diameter of which there are recesses in contact with the ratchet pawl

2. The device. O p. 1, I distinguish -; This is due to the fact that, in order to lubricate the wedge, during operation, it is equipped with an oiler made in the form of a pipe made of elastic material, the end of which follows the formulas cl.
