Изобретение относитс к полиграфической технологии, а именно к способу определени глубины травлени в процессе изготовлени форм глубокой печати.The invention relates to printing technology, in particular to a method for determining the etching depth in the process of making intaglio printing forms.
Известен способ изготовлени клиньев элекгролитическим способом, основанный на использовании рассеивающей способности ванны.A known method of making wedges by an electrolytic method is based on the use of the scattering power of the bath.
При этом способе отдельные участки поверхности катода (анода) наход тс на различных рассто ни х от анода (катода), плотность тока на них различна и обратно пропорциональна рассто ни м. Однако и это не обеспечивает посто нства получени заданного профил клина из-за невозможности создани закономерно измен ющегос распределени тока на поверхности электродов.In this method, individual areas of the cathode (anode) surface are at different distances from the anode (cathode), the current density on them is different and inversely proportional to the distances m. However, this does not ensure the stability of the specified wedge profile. creating a regularly changing current distribution on the surface of the electrodes.
С целью повышени качества клиньев-датчиков травление металлической заготовки, вл ющейс анодом, ведут при погружении в электролит с посто нной заранее рассчитанной дл достижени заданного профил клипа скоростью; изменение плотности тока производитс автоматически и составл ет посто нную величину, например 50 а/дм. Травление образца при этом можно осуществл ть несколько раз.In order to improve the quality of wedges-sensors, etching of a metal billet, which is an anode, is carried out when immersed in an electrolyte at a constant rate calculated in advance to achieve a given profile of a clip; the change in current density is made automatically and is a constant value, for example 50 a / dm. The sample can be etched several times.
На чертеже изображена установка дл осуществлени способа.The drawing shows an apparatus for carrying out the method.
В винипластовой ванне 1 с хромовым электролитом 2 наход тс пластинка 3 3 нерл авеющей стали (катод) и медный образец 4, представл ющий собой полоску медной прокатанной фольги толщиной 50-0,5 мкм (анод). Образец 4 приводитс в движение от мотора 5, позвол ющего с заранее рассчптанной и посто нной или переменной скоростью перемещать образец в вертикальном положении при помощи привода 6. Ток от псточника питани 7 автоматически регулируетс устройством 8.In the vinyl plastic bath 1 with chromic electrolyte 2 there is a plate 3 3 of stainless steel (cathode) and a copper sample 4, which is a strip of copper rolled foil with a thickness of 50-0.5 μm (anode). Sample 4 is driven by a motor 5, which allows the sample to be moved in a vertical position by means of a drive 6 with a previously calculated and constant or variable speed. The current from the power supply 7 is automatically controlled by the device 8.
Предмет изобретени Subject invention
Способ изготовлени клиньев-датчиков, заключающийс в избирательиом электролит ческом травлении металлической заготовки, о т л и ч а ю щ п и с тем, что, с целью повыщенп нх качества, травление металлической заготовки ведут при погружении в электролит с посто нной скоростью, измен плотность тока при сохранеппп ее значени посто нной на единицу погружаемой поверхности.A method of manufacturing sensor wedges, consisting in selective electrolytic etching of a metal billet, has the effect that, in order to increase the quality of the metal, the etching of the metal billet is carried out when immersed in the electrolyte at a constant rate. current density when its values are constant per unit of the surface being immersed.
