Description
(Л(L
с: Изобретение касаетс держащей поверхности на устройствах захвато листа в листообрабатывающих и листоперерабатьшающих машинах. Известны держащие поверхности на устройствах захватов листа, при чем держаща поверхность снабжена профилем, который состоит из основ ного материала держащей поверхности (патент DD № 1411 126). Недостатком вл етс то, что пр филь держащих поверхностей состоит из относительно м гкого основного материала держащих поверхностей и поэтому не обладает достаточ ной износостойкостью. Применение закалки дл снижени износа вызьюает необходимость последукидей обработки, в результате чего по вл ютс неправильности профил , обуславливавшие уменьшени держащей силы. Цель изобретени - создание дер жащих поверхностей на устройствах захватов листа, которые имеют боль шую износостойкость и вл ютс экономично изготовл емыми. Задача изобретени состоит в то чтобы избегать сдвига листов между держапщми поверхност ми захватов листа и опорной поверхности захватов листа вследствие уменьшени 3 держащей силы в результате влений. износа профилированной держащей поверхности . Поставленна цель достигаетс тем, что профиль держащей поверхности покрыт слоем зерен металлического окисла или карбида средней ве- i личины в 10 мкм. На чертел р изображена держаща поверхность с профилем, разрез. Держаща поверхность 1 снабжена равномерным профилем 2, который состоит из основного материала 3 держащей поверхности 1 и по1фыт слоем 4, зерен 5 металлического окисла или карбида средней величины в 10 мкм. Зерна металлического окисла или карбида состо т преимущественно из хрома, титана, вольфрама или алюмини . Таким образом, м гкий, оснащенный профилем основной материал снабжен износостойкой держащей поверхностью, что позвол ет избежать уменьшение держащей силы вследствие износа профилированной держащей поверхности . Признано изобретением по результатам экспертизы, осуществленной ведомством по Изобретательству Германской Демократической Республики.c: The invention relates to a holding surface on a sheet gripping device in sheet processing and sheet processing machines. Holding surfaces are known on devices for gripping a sheet, and the holding surface is provided with a profile that consists of a base material of the holding surface (DD Patent No. 1411 126). The disadvantage is that the filter of the holding surfaces consists of a relatively soft base material of the holding surfaces and therefore does not have sufficient wear resistance. The use of quenching to reduce wear causes the need for post-treatment processing, resulting in irregularities in the profile causing a decrease in holding force. The purpose of the invention is to provide holding surfaces on sheet gripping devices, which have high wear resistance and are economically fabricated. The object of the invention is to avoid sheets shifting between the holding surfaces of the sheet grippers and the supporting surface of the sheet grippers due to a decrease in 3 of the holding force as a result of the phenomena. wear profiled holding surface. The goal is achieved by the fact that the profile of the holding surface is covered with a layer of grains of metallic oxide or carbide of average size of 10 µm. Ink p is depicted holding a surface with a profile, a slit. The holding surface 1 is provided with a uniform profile 2, which consists of the base material 3 of the holding surface 1 and with 1 layer 4, grains 5 of metal oxide or carbide of an average size of 10 μm. Metal oxide or carbide grains consist predominantly of chromium, titanium, tungsten or aluminum. Thus, a soft, profiled base material is provided with a wear resistant holding surface, which avoids a decrease in the holding force due to the wear of the shaped holding surface. Recognized as an invention according to the results of the examination carried out by the Office for the Invention of the German Democratic Republic.
