(54) ШТАМП ДЛЯ ПРАВКИ-КАЛИБРОВКИ КОЛЬЦЕВЫХ(54) STAMP FOR EDITING-CALIBRATION OF RING

ДЕТАЛЕЙDETAILS

II

Изобретение относитс к обработке металлов давлением, а именно, к оснастке дл изготовлени кольцевых деталей, и может быть использовано в производстве двигателей летательных аппаратов, а также других отрасл х машиностроени - судостроении , сельскохоз йственном, химическом и др.The invention relates to the processing of metals by pressure, in particular, to equipment for the manufacture of ring parts, and can be used in the manufacture of aircraft engines, as well as other parts of the engineering industry - shipbuilding, agricultural, chemical, etc.

Известен штамп, состо щий из опорной и прижимной плит и пуансона, состо ш,его из конуса и секторов, установленных с возможностью перемещени в радиальном направлении 1.A stamp is known, consisting of a support plate and a pressure plate and a punch, consisting of a cone and sectors mounted for movement in the radial direction 1.

Недостатком щтампа вл етс то, что вследствие изготовлени кольцевой детали с допуском по высоте при правке деталей с плюсовым допуском на высоту снимаетс прижимной плитой торцова поверхность детали , либо при минусовом допуске на высоту детали раздавливаютс секторы разжимного пуансона. В результате, в первом случае наблюдаетс изготовление детали с низким качеством правки по плоскости, а во втором случае - быстрый износ секторов разжимного пуансона при низком качестве правки.The disadvantage of the chip is that, due to the manufacture of the ring part with a height tolerance, the end face of the part is removed by the pressure plate when the parts with the plus height tolerance are edited, or when the height tolerance of the part is reduced, the unclamp punch sectors are crushed. As a result, in the first case, a part with a low quality of straightening on the plane is observed, and in the second case, rapid wear of the unclamping punch sectors with a low quality of straightening.

Цель изобретени - повышение качества правки деталей по плоскости.The purpose of the invention is to improve the quality of editing parts on the plane.

Поставленна цель достигаетс тем, что каждый сектор выполнен разъемным по высоте и состоит из двух частей, установленных с возможностью относительного перемещени вдоль оси пуансона и подпружиненных одна относительно другой, при это.м линии разъема секторов расположены на разных высотах одна относительно другой.The goal is achieved by the fact that each sector is made detachable in height and consists of two parts, installed with the possibility of relative movement along the axis of the punch and spring-loaded one relative to the other, with this, the line of separation of the sectors are located at different heights one relative to another.

На фиг. 1 изображен штамп, общий вид; на фиг. 2 - сектор; на фиг. 3 - то же, вид сверху.FIG. 1 shows a stamp, a general view; in fig. 2 - sector; in fig. 3 - the same, top view.

Штамп дл правки-калибровки содержит прижимную и опорную плиты 1 и 2, пуансон , содержащий установленный вдоль оси щтампа конус 3 и размещенные вокруг него и взаимодействующие с конусом секторы 4. Каждый сектор выполнен из двух частей: нижней а и верхней б, установленных с возможностью перемещени вдоль оси щтампа относительно друг друга с помощью винтовой пружины 5.The stamp for calibration calibration contains pressure plate and base plate 1 and 2, a punch containing a cone 3 installed along the axle axis and placed around it and sectors 4 interacting with the cone. Each sector is made of two parts: lower a and upper b, installed with moving along the axis of the axle relative to each other using a helical spring 5.

Claims

The upper part b is moved relative to the bottom a and is carried out on the fingers 6, which are fixed to the lower part on the connector and have a head 7. The cylindrical sockets 8 are made for the head of the finger and the springs in parts of sectors 8. The connector lines c, d, etc. each sector is offset from the neighboring sectors in height. It is most advisable to arrange them in a checkerboard pattern, as shown in FIG. 1. The stamp works as follows. The ring part 9 is installed on the plate 2, and a stamp on the press table (not shown). The height has a tolerance of 5; in this case, each of the sectors is adjusted to the upper limit of the tolerance of the ring. has a height greater than or equal to mm) where H is the height of the continuous sector is equal to the nominal height of the ring. At 1 slot, the connector is taken equal to the tolerance zero of this ring size. When lowering the movable traverse of the press (not shown), the pressing plate 1 presses first to the upper movable part of sector 4, the ring part 9 and sectors 4 are aligned in height and the part 9 and sectors 4 are pressed to the base plate 1 by straightening the part along the plane. In this case, the ring part 9 is loaded by force Rl from the pressure plate, and sectors 4 - only by force of compressed springs, which are several orders of magnitude smaller than P. If further lowering the press crosshead, the cone 3 expands the sectors 4 and calibrates the part 9 according to the diameter with the force P, while the clamp is turned off. Claim 1. Stamp for editing-calibration of ring parts, comprising a base plate for mounting an annular part, a pressure plate and a punch, made in the form of a cone and interacting with it sectors mounted for movement in the radial direction, characterized in that improving the quality of editing, each sector is made detachable in height and consists of two parts installed with the possibility of relative movement along the axis of the punch and spring-loaded one relative to the other.

2. A stamp in accordance with claim 1, characterized in that the sector's connector lines are located at different heights one relative to another.
