(5) УСТРОЙСТВО дл ПРАВКИ И КАЛИБРОВКИ КОЛЬЦЕВЫХ ДЕТАЛЕЙ(5) DEVICE FOR CORRECTION AND CALIBRATION OF RING DETAILS

II

Изобретение относитс к обработке металлов давлением, в частности к устройствам дл правки и калибровки кольцевых деталей, и может быть использовано в машиностроительной, судостроительной , химической и других отрасл х промышленности.The invention relates to the processing of metals by pressure, in particular to devices for straightening and calibrating ring parts, and can be used in the engineering, shipbuilding, chemical and other industries.

Известен штамп с разжимным пуансоном , предназначенный дл калибровки цилиндрических заготовок, содержащий опорную и прижимную плиты и конусной пуансон с расположенными на нем разжимными секторами, выполненными в виде клиньев СПНедостатком этого устройства вл етс невозможность осуществлени правки кольцевой детали по ее торцовым плоскост м.A known punch with an expanding punch for calibrating cylindrical blanks containing supporting and clamping plates and a conical punch with expansion sectors located on it, made in the form of SP wedges. The disadvantage of this device is the impossibility of straightening the ring part along its face planes.

Известно также устройство дл обработки кольцевых деталей, содержащее опорный стол, установленную с возможностью перемещени перпендикул рно его поверхности прижимную плиту и разжимной механизм в виде конусногоIt is also known a device for processing annular parts, comprising a supporting table, mounted with the possibility of moving a clamping plate perpendicular to its surface and an expanding mechanism in the form of a conical

пуансона с секторами. Устройство позвол ет производить одновременно калибровку внутреннего диаметра кольцевого издели и правку его по торцовым поверхност м, контактирующим с рабочими поверхност ми прижимной плиты и заплечиками разжимных секторов 2,punch with sectors. The device makes it possible to simultaneously calibrate the inner diameter of the annular product and to straighten it on the end surfaces in contact with the working surfaces of the pressure plate and shoulders of the expansion sectors 2,

Недостатком известного устройства вл етс невысокое качество правки обрабатываемой детали.Это объ сн етс , тем, что при калибровке издели между его торцом и прижимной плитой возникают значительные контактные нагрузки, а,следовательно, и большие силы трени , которые, в свою очередь, вызывают искажение геометрической формы заготовки и нарушают чистоту ее торцовой поверхности.A disadvantage of the known device is the low quality of the dressing of the workpiece. This is due to the fact that when calibrating the product between its end face and the pressure plate, there are significant contact loads, and, consequently, large friction forces, which, in turn, distort geometric shape of the workpiece and violate the purity of its end surface.

Цель изобретени - повышение качества правки.The purpose of the invention is to improve the quality of edits.

Claims

This goal is achieved by the fact that the device for straightening and calibrating ring parts, comprising a supporting table mounted with the possibility of moving perpendicular to its surface, the pressure plate and the expanding mechanism in the form of a conical punch with sectors, are provided with inserts placed on the pressure plate with the possibility reciprocating movement in the radial direction. FIG. 1 shows the device, the main view; in fig. 2 - the same plan view. The device for straightening and calibration has a support table 1 on which an expanding mechanism is installed, including expanding sectors 2 and interchangeable sectors 3. Radial movement of the pressing sectors is carried out by a conical punch 4. The movable traverse (not shown) bears the pressure plate 5 by moving it perpendicular to the surface of the table. The plates of the plates are provided with bearing shells 6, which are mounted on the working surface of the plate facing the end of the ring 7 that they interact with. The liners 6 are located on the plate 5 in the grooves with the possibility of their radial movement, for example, using a lubricant, the role of covs or balls between the plate and the liner. Inserts 6 protrude above the slab surface by the value of 0, mm. The number of inserts 6 is equal to the number of sector 3. The smallest width of the insert is calculated from the condition of resistance of the material of the ring of 4 cm; The device works as follows. An annular billet 7, with the raised presser plate 5 and the punch 4, is mounted on the shoulders of sectors 2. Then the movable traverse is lowered; with the pressure plate 5 and the inserts 6. The inserts 6 presses the ring k to the shoulders of sectors 2, the surfaces of which are parallel to the surface of the table 1. In this case, the ends of the ring 7 are straightened in a plane, thereby eliminating waviness along the contour and its saber. Then, without removing the clamping plate force, a punch stroke is performed, which pushes the sectors 2 and 3 apart, acting on the ring 7 and deforming it. In this case, the machined ring is in contact with the bearing inserts 6, forming the working surface of the plate 5 and moving with them. Thus, sectors 2 and 3 | ring 7 and inserts 6 simultaneously move by the same amount, which eliminates unevenness of deformation and elimination of the workpiece , which contributes to the quality of editing details. Claims device for straightening and calibrating ring parts, comprising a support table, mounted with the possibility of moving a clamping plate perpendicularly to its surface and an expanding mechanism in the form of a conical punch with sectors, characterized in that, in order to improve the quality of editing, it is provided with inserts placed on the pressure plate with the possibility of reciprocating movement in the radial direction.
