(З) УСТРОЙСТВО дл ЭЛЕКТРОЭРОЗйОННОГО РЕЗАНИЯ (W) DEVICE FOR ELECTRIC EASY CUTTING

Л. . :.. L. : ..

Изобретение относитс к электро-, эрозионной обработке и может быть j использовано дл резки металла. The invention relates to electro-erosion treatment and can be used for metal cutting.

Известно устройство дл электрофизической резки металла электродоминструментом , выполненным в виде враг дающегос тонкого диска, укрепленного на валу между двум зажимами, образующими полость, через которую рабоча среда подаетс в зону обработки на боковые поверхности диска 1J.A device for electrophysical metal cutting with an electro-tool, made in the form of an enemy of a thin disk mounted on a shaft between two clamps forming a cavity through which the working medium is fed into the treatment area on the side surfaces of the 1J disk is known.

Недостатком известного устройства вл етс то, что из-за креплени аажима посредством болтовi гюток жидкости разбиваетс , давление его незначительно , что не позвол ет получить достаточно высокую производительность резани .A disadvantage of the known device is that due to the fastening of an AJM by means of bolts, the fluid's bites break, its pressure is insignificant, which does not allow to obtain a sufficiently high cutting performance.

Целью насто щего изобретени вл етс повышение производительности устройства путем улучшени сплошности потока Жидкости на рабочих поверхност х диска и более эффектив .МЕТАЛЛОВThe purpose of the present invention is to improve the performance of the device by improving the continuity of the flow of liquid on the working surfaces of the disk and more efficiently. METALS

j Horo удалени продуктов эрозии из межзлектродного прбмежутка..j Horo removal of erosion products from the inter electrode electrode.

Дл достижени этой цели на диске выполнены сквозные щели в форме дуг, равномерно расположенные по поверхности диска, а каждый за)хим состоит из двух частей, соединенных при помощи резьбы, так, что охватывающий элемент навинчивают на охватываемый . Тем самым образуетс полость между выполненными на элементах зажима коническим 1 поверхност ми , обраценными большим диаметром к диску.To achieve this goal, the disk has through slots in the form of arcs evenly spaced along the surface of the disk, and each of them consists of two parts connected by a thread, so that the surrounding element is screwed onto the male one. Thereby, a cavity is formed between the conic-1 surfaces formed on the clamping elements, having a large diameter to the disk.

Таким образом, зажимы по всей окружности образуют щель, регулируемую по ширине благодар резьбовому соединению элементов,через которую жидкость поступает на боковые поверхности диска.Thus, the clips around the entire circumference form a slit, adjustable in width due to the threaded connection of the elements, through which the liquid enters the side surfaces of the disk.

Claims

FIG. 1 shows the electrode tool; in fig. 2 - a general view of the device in section; In disk I, arcuate slots are cut.

2. Width In the slit is chosen depending on the density conditions of the pacTV thief, fluid viscosity, cutting mode, material equal to 1-3 disk thicknesses. The radius of the slit centerline is determined by the formula Ksch. (where R is the radius of the disk. The electrode tool is mounted on wa 3 with cavity i. At the same time, the disk is held in the vertical plane of the clamp 5, consisting of a guide 6 and an outer limiter 7 between which a cone-shaped cavity 8 is formed. Threaded connection of two parts the clamp allows you to regulate the volume of the cavity 8 and the magnitude of the gap 9 between the clamp end and the side surface of the disk. The electrode tool works as follows. When the disk 1 mounted on the shaft 3 rotates, the liquid flows from the cavity under pressure into the cavity 8, and then -through slots 9 - on the lateral surfaces of the disk. The arcuate slots 2, which are cut in the disk, create additional fluid pressure in the interelectrode gap, which intensifies the evacuation of erosion products, improves the continuity of the bone's fluid on the periphery of the disk. the disk through the slot 9 in a continuous stream close to the center of rotation of the disk and covers the entire surface of the disk evenly, the cutting process can be carried out more intensively, not allowing local disk overheating and preventing short circuits. DETAILED DESCRIPTION OF THE INVENTION A device for electrically erosive cutting of metals by an electrode driven tool in the form of a disk mounted on an interAU shaft with two clamps forming a cavity for supplying the working medium to the treatment area along the lateral surfaces of the disk so that, in order to increase productivity by improving the continuity of flow and intensive removal of erosion products, each clamp is made of two elements coaxially mounted on the shaft, articulated with each other by a threaded connection, and The cavity is formed by conical surfaces formed on the clamping elements, the large diameters of which face the disk, while in the latter there are through arcuate i slits, the width of which is chosen within 1-3 disk thicknesses.
