Description
Известны пружинные съемники в штамнах дл пробивки отверстий в гетинаксовых платах с печатным монтажом. Прижим и съем детали в этих штампах во врем вырубани пуансоном и его выхода из гетинакса осуществл ютс прижимной плитой (съемником). Такой съемник не обеспечивает равномерный прижим в местах вырубки отверстий, ввиду непараллельности и неплоскостности примен емого фольгированного гетинакса. Это ведет к окислению поверхностного сло гетинакса вокруг вырубаемого отверсти .Spring-loaded pullers are known in strains for punching holes in printed circuit mounting plates. The pressing and removal of parts in these dies during punching and punching out of the getinkaX are carried out by a pressure plate (stripper). Such a puller does not provide a uniform clamping in the places of cutting holes, due to the non-parallelism and non-flatness of the foil-type getinax used. This leads to the oxidation of the surface layer of getinax around the hole being cut.
Этот недостаток устран етс применением дл каждого пуансона отдельного пружинного съемника в качестве устройства, устран ющего отслоени на поверхности панелей при вырубании в них отверстий.This disadvantage is eliminated by using for each punch a separate spring puller as a device that eliminates peeling on the surface of the panels when cutting holes in them.
На чертеже изображены один из пуансонов с пружинным съемником и матрица.The drawing shows one of the punches with a spring puller and the matrix.
При движении пуансона / вниз, принсимна втулка 2 под действием Пружинного съемника 3 во врем вырубки отверстий и съема платы прижимает гетинаксовую плату 4. Этим обеспечиваетс прижим панели к поверхности вокруг вырубаемого отверсти и предотвращаетс на этом участке поверхностное ее отслоение.When the punch moves / down, the sleeve 2, under the action of the spring-loaded puller 3, during the cutting of holes and the removal of the board, presses the getanix board 4. This ensures that the panel is pressed against the surface around the hole being cut and its surface is peeled off.
Предмет изобретени Subject invention
Применение упругих, например, пружинных съемников, отдельных дл каждого пуансона, в качестве устройства, устран ющего отслоение на поверхности панелей, например из гетинакса, при вырубке в них отверстий на штампах-The use of elastic, for example, spring-type pullers, separate for each punch, as a device that eliminates peeling on the surface of panels, for example, from a getinax, when cutting holes in the stamps in them
