Изобретение относитс к обработке металлов давлением, а именно к способам изготовлени деталей с конической полостью.The invention relates to the processing of metals by pressure, in particular to methods for the manufacture of parts with a conical cavity.
Известен способ изготовлени деталей с конической полостью из плоской заготовки за три последовательных операции, на первой из которых получают цилиндрический полуфабрикат, внутренний диаметр которого равен минимальному диаметру полости готовой детали, на второй - осуществл ют раздачу полуфабриката, увеличива его диаметр со стороны открытого торца, а на третьей - производит окончательную выт жку детали коническим пуансоном в матрицу fi.A known method of manufacturing parts with a conical cavity from a flat billet in three successive operations, the first of which produces a cylindrical semi-finished product, the internal diameter of which is equal to the minimum diameter of the cavity of the finished part, the second distributing the semi-finished product, increasing its diameter from the open end, and on the third, it produces the final stretching of the part by a conical punch into the matrix fi.
Недостатком этого способа вл етс мала относительна высота деталей, обусловлен .на тем, что внутренний диаметр цилиндрического полуфабриката равен минимальному полости готовой детали и поэтому в начальной стадии окончательной выт жки идет только калибровка заготовки и относительна высота детали практически не набираетс . Деформаци детали идет в основном в конечной стадии последней операции, что позвол ет получать детали с небольшой относительной высотой.The disadvantage of this method is the small relative height of the parts, due to the fact that the internal diameter of the cylindrical semi-finished product is equal to the minimum cavity of the finished part and therefore, in the initial stage of the final stretch, there is only a calibration of the workpiece and the relative height of the part is almost not collected. The deformation of the part proceeds mainly in the final stage of the last operation, which makes it possible to obtain parts with a small relative height.
Цель изобретени - увеличение относительной высоты деталей.The purpose of the invention is to increase the relative height of the parts.
Указанна цель достигаетс тем, что цилиндрический полуфабрикат получают с внутренним диаметром, большим максимального диаметра полости готовой детали, а на второй операции путем обжима уменьшают диаметр полости полуфабриката со стороны открытого торца до максимального диаметра в готовой детали. На фиг. 1 схематически показан цилиндрический полуфабрикат; на фиг. 2 - обжа10 тый полуфабрикат; на фиг. 3 - готова деталь .This goal is achieved by the fact that a cylindrical semi-finished product is obtained with an inner diameter greater than the maximum diameter of the cavity of the finished part, and in the second operation by crimping the diameter of the semi-finished product is reduced from the open end to the maximum diameter in the finished part. FIG. 1 schematically shows a cylindrical semi-finished product; in fig. 2 — baked semi-finished product; in fig. 3 - ready detail.
Способ осуществл ют следующим образом .The method is carried out as follows.
1515
На первой операции, например обратным выдавливанием, получают цилиндрический полуфабрикат с внутренним диаметром, большим максимального диаметра полости готовой детали примерно на 15-20%- На второй 20 операции путем обжима уменьшают диаметр полости полуфабриката со стороны открытого торца до максимального диаметра в готовой детали, т.е. также на 15-20%. На третьей операции производ т окончательнуюIn the first operation, for example, by reverse extrusion, a cylindrical semi-finished product with an internal diameter greater than the maximum diameter of the cavity of the finished part is obtained by about 15-20% - In the second 20 operations, the diameter of the cavity of the semi-finished product from the open end is reduced by crimping to . also by 15-20%. In the third operation, the final
