Изобретение относитс к технологии машиностроени , в частности к изготовлению окон в детал х распределительных устройств гидравлических объемных машин, например, золотники плаиетарно-роторного гидромотора.The invention relates to mechanical engineering technology, in particular, to the manufacture of windows in the distributor components of hydraulic volumetric machines, for example, spools of a rotary hydraulic motor.
Известен способ изготовлени окон в цилиндрических детал х распределительных устройств, заключающийс в том, что на рабочем торце заготовки детали равномерно по окружности выполн ют цилиндрические отверсти , а затем эти отверсти частично перекрывают с обеспечением заданного проходного сечени , например путем прижати пластин по сторонам каждого отверсти 1.A known method of manufacturing windows in cylindrical parts of distribution devices consists in that cylindrical holes are made at the working end of the workpiece, and then these holes are partially covered to ensure a given flow area, for example by pressing plates on the sides of each hole 1 .
Однако известный способ обладает тем недостатком, что он сложен в технологическом выполнении, а кроме того, не обеспечиваетс точна припайка пластин и, следовательно , не обеспечиваетс точное и одинаковое проходное сечение всех окон в детали .However, the known method has the disadvantage that it is difficult to process, and in addition, the plates are not accurately soldered and, consequently, an exact and identical flow area of all the windows in the part is not provided.
Цель изобретени - упрощение технологии и повышение точности проходного сечени окон.The purpose of the invention is to simplify the technology and improve the accuracy of the window section.
Поставленна цель достигаетс тем, что в способе изгбтовлени окон в цилиндрических детал х распределительных устройств, заключающемс в том, что на рабочем торце заготовки детали равномерно по окружности выполн ют цилиндрические отверсти , а затем эти отверсти частично перекрывают 5 с обеспечением заданного проходного сечени , на рабочем торце заготовки детали между отверсти ми выполн ют технологические выступы, а частичные перекрыти отверстий осуществл ют путем пластической jj деформации выступов.The goal is achieved by the fact that in the process of bending windows in cylindrical parts of distributing devices, the fact is that cylindrical holes are made at the working end of the workpiece, and then these holes partially overlap 5 with the desired cross section. The end of the workpiece between the holes is made technological protrusions, and the partial overlap of the holes is carried out by plastic jj deformation of the projections.

Figure 1 shows a workpiece with technological projections made between previously formed cylindrical webs; in fig. 2 is the same, view A in FIG. one; in fig. 3 — billet of a part after deformation of technological protrusions and partially blocked holes; in fig. 4 is the same, view B in FIG. 3; in fig. 5 - ready detail of the distribution devices of the planets; in fig. 6 is the same, view B in FIG. five.
Способ реализуетс следующим образом.The method is implemented as follows.
На рабочем торце заготовки 1 детали равномерно по окружности выполн ют цилиндрические отверсти 2 и технологические выступы 3 над перемычками между отверсти ми 2. Затем изготовленную заготовку 1 с технологическим выступом устаиавливают на пресс и пуансоном (не показан), снабженного зубь ми, имеющими форму окон, производ т пластическую деформацию выступов и калибровку окон 4 усилием пресса. В результате пластической деформации этих выступов с боков происходит частичное закрытие отверстий 2 и образование окон 4 заданной конфигурации с площадью в торцовом сечении соизмеримой с площадью окон 4 готовой детали 5.At the working end of the workpiece 1, the cylindrical holes 2 and technological protrusions 3 above the bridges between the holes 2 are made uniformly around the circumference. Then, the manufactured workpiece 1 with a technological protrusion is placed on a press and a punch (not shown) equipped with window shaped teeth, the protrusions are plastic deformed and the windows 4 are calibrated by a press force. As a result of plastic deformation of these protrusions from the sides, the holes 2 are partially closed and the windows 4 are formed of a given configuration with an area in the end section comparable to the area of the windows 4 of the finished part 5.
Пример. Вытачивали заготовку 1 0 100 мм и высотой 40 мм. Равномерно по окружности на рабочем торце заготовки просверливали отверсти 2 8 мм и глубиной 10-15 мм. Со стороны рабочего торца с отверсти ми заготовка протачивалась дл образовани выступов 3 высотой 4 мм между отверсти ми по перемычке между ними. Затем выступы под прессом пластически деформировались дл частичного перекрыти отверстий в плоскости торца. Пуансоном под прессом (прорезаютс ) калибруютс окна 4 согласно требуемого проходного сечени . После чего заготовку обрабатывают до полного получени детали 5 - золотники планетарно-роторного гидромотора.Example. Grind the workpiece 1 0 100 mm and a height of 40 mm. Evenly around the circumference at the working end of the workpiece, 2 8 mm holes and 10-15 mm deep holes were drilled. From the side of the working end with holes, the workpiece was machined to form protrusions 3 with a height of 4 mm between the holes along the bridge between them. Then the protrusions under the press plastically deformed to partially block the holes in the plane of the end face. The punch under pressure (cut through) calibrates windows 4 according to the required flow area. After that, the workpiece is processed to complete the parts 5 - the spools of the planetary-rotary hydraulic motor.
Предложенный способ изготовлени окон в детал х распределительных устройств позвол ет увеличить производительность труда за счет сокращени количества операций; повысить точность изготовлени окон; снизить трудоемкость изготовлени деталей распределительйых устройств.The proposed method of manufacturing windows in switchgear parts allows increasing labor productivity by reducing the number of operations; improve the accuracy of manufacture of windows; reduce the labor intensity of manufacturing parts for distributor devices.
