Description
ii
Изобретение относитс к области холодной штамновки II может быть применено, например , дп выт жки и обрезки из пенты пустотелых деталей с плоским дном в автматических устройствах.The invention relates to the field of cold punch II, for example, dp can be used for stretching and cutting out of the penta hollow parts with a flat bottom in automatics devices.
Известен способ изготовлени полых изделий Щ путем выт жки и съема готового издели с пуансона нижней кромки матрицы при обратном ходе пуансона Этот способ возможен благодар тому, что вследствие внутренних напр жений верхн кромка готовой детали немного открываетс .A known method for manufacturing hollow products U by drawing and removing the finished product from the die of the lower edge of the die during the reverse course of the die. This method is possible due to the fact that due to internal stresses the upper edge of the finished part opens slightly.
Недостатком этого способа вл етс невозмож11ость получени детали с ровным открытым торцом,The disadvantage of this method is the impossibility of obtaining a part with an even open end,
Известен также способ изготовлени полых изделий в комбинированных штамлахAlso known is a method of making hollow articles in combined strains.
) нутем выт жи обрезки торца и съем готового издели с щ ансона.) Numeral end trimming and removal of the finished product from the plate.
Однако при использовании этого способа деталь снимают лишь с применением верхнего выталкивател , но в этом случае деталь остаетс над матрицей и ее трудно ориентировать дл дальнейшей обработки, However, when using this method, the part is removed only with the use of the upper ejector, but in this case the part remains above the die and it is difficult to orient it for further processing,
Дл упрощени конструкции оснастки и облегчени съема готового издели после обрезки по высоте осуществл ют рихтовку дна издели .To simplify the construction of the tooling and facilitate the removal of the finished product after trimming in height, the bottom of the product is trimmed.
Изобретение по сн етс чертелдам, где дана технологическа схема изготовлени полых изделий.The invention is explained in Chertandi, where the technological scheme for the manufacture of hollow articles is given.
Предлагаемый способ осуществл етс следующим, образомThe proposed method is carried out as follows.
В ленте пуансона производитс выт жк а. на требуем -ю глубину, затем обрезка о кромок по высоте5далее рихтовка дна &, после которой открываетс верхн кромка издели , и сн тие издели с пуансона г кромкой матрицы при обратном ходе пуансона. Отрезанный отход остаетс соединенным с лентой.The punch tape is pulled out. at the required depth, then trimming along the edges at a height of 5, further leveling the bottom &, after which the upper edge of the product opens, and removing the product from the punch with the edge of the die during the reverse course of the punch. The cut waste remains connected to the belt.
