Vynález sa týká elektrolytu k nanášaniudeformačných sieLí na ocelové plechy, spů-sobu a zariadenia na jeho přípravu. V strojárskom tvárnění, najmá plošnom,je často potřebné zmerať velkost plastic-kých deformácií na skúšobných vzorkáchalebo priamo na výrobkoch — výťažkoch,ohýbaných súčiastikách a podobné. V súčasnosti je k- dlspozícll progresívnyspůsob nanášania deformačných sietí zaria-dením, pomocou kterého sa elektrochemic-kým sposoboim prenáša zo šablony na kovzvolená deformačná sleť, resp. ivzor, aký našabloně je. Výhodou tohoto sposobu je, žesiete podlá něho. nanesené majú přesné roz-měry, sú zřetelné a nezmazatelné, pričompovrch plechu nie je mechanicky poškode-ný ako pri vyhotovovaní sietí vyrýváním.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an electrolyte for application to the formation of a network of steel sheets, a method and apparatus for its preparation. In mechanical engineering, in particular, it is often necessary to measure the size of plastic deformations on test specimens or directly on products - extracts, bent parts and the like. At present, a progressive method of applying deformation nets to the device by means of which the electrochemical method is transferred from the template to the metal deformation bar, respectively, is provided. the pattern as the pattern is. The advantage of this method is that you make it. they have exact dimensions, they are distinct and indelible, and the surface of the sheet is not mechanically damaged as in the drawing up of nets.
Zariadenie sa skládá zo zdroja jednosměr-ného a striedavého elektrického prúdu avalčekOvacieho zariadenia, napojeného natento zdroj. K prevádzke zariadenia je po-třebná šablona so vzorom, ktorý sa bude na-nášať, ďalej elektrolyt a neutralyt.The device consists of a source of unidirectional and alternating electric current and a power supply device connected to the source. A template with a pattern to be loaded, an electrolyte and a neutrality, is required to operate the device.
Doteraz používaný elektrolyt obsahuje ve-la chemických látok: dusičnan kobaltnatý,chlorid vápenatý, chlorid amónny, kyselinucitrónovú, kyselinu octová, vodu, atď. Pripráci s uvedeným elektrolytom vznikajú vý-pary, ktoré dráždia dýchacie orgány aj zraka pri dlhšie trvajúcom působení zapríčiňujúbolesti hlavy a nevolnost.The electrolyte used so far contains very chemical substances: cobalt nitrate, calcium chloride, ammonium chloride, acid-citric acid, acetic acid, water, etc. The use of this electrolyte results in vapors that irritate the respiratory system and the eye, causing prolonged exposure to headaches and nausea.
Uvedené nevýhody možno v podstatnejmiere odstrániť elektrolytom podlá vynále-zu, ktorého podstata spočívá v tom, že ob-sahuje 4,5 až 5 % hmot. 31 až 32 %-nej ky-seliny chlorovodíkovej, 0,03 až 0,04 % hmot.dvojchromanu draselného a zvyšok do 100percent hmot. tvoří ivoda.The above disadvantages can be substantially eliminated by the electrolyte according to the invention, which comprises 4.5 to 5 wt. 31 to 32% hydrochloric acid, 0.03 to 0.04% by weight of potassium dichromate and the remainder to 100 percent by weight of hydrochloric acid; forms the water.
Podstata sposobu přípravy elektrolytu po-dlá vynálezu spočívá v tom, že po zmiešaníkyseliny chlorovodíkovej, dvojchromanu dra-selného a vody sa cez vytvořený roztok ne-chá pretekať elektrický prúd o napatí T2 až18 V a intenzitě 8 až 13 A po dobu 6 až 8minut a potom sa hotový elektrolyt precedícez papierovú vatu.The principle of the process of preparing the electrolyte according to the invention is that after mixing the hydrochloric acid, potassium dichromate and water, a current of T2 to 18 V and an intensity of 8 to 13 A for 6 to 8 minutes is not allowed to flow through the solution formed; then the finished electrolyte is precoated with cotton wool.
Podstata zariadenia na vykonáváme spo-sobu přípravy předmětného elektrolytu spo-čívá v tom, že pozostáva z rámu, v ktoromsú nad sebou otočné uložené horný válec aspodný válec potiahnutý pistou, pričom hor-ný válec dosadá na spodný válec, ktorý jesvojou spodnou častou umiestnený v miske pre elektrolyt, pričom horný válec je najednej straně opatřený pohonom a na dru-hej straně opatřený kontaktom pre pripoje-nie kladného pólu zdroja a spodný válec jeopatřený kontaktom pre pripojenie záporné-ho pólu zdroja. Výhodou elektrolytu podlá vynálezu je, žek jeho výrobě je potřebné menej surovin,čo do drúhov aj množstva, pričom sa jednáo suroviny 1'ahko dostupné a lacnejšie. Dal-šou jeho výhodou je, že výpary vznikajúcepri práci s ním nespůsobujú zdravotně ťaž-kosti. Výrobně náklady elektrolytu podlá vyná-lezu sú mnohonásobné nižšie ako je cenadoteraz používaného elektrolytu. Ďalšou výhodou elektrolytu podlá vyná-lezu je, že plechy so sieťami ním nanesený-mi je možné neutralizovat roztokem 50 mlvodného skla v 950 ml vody, čím odpadá po-třeba drahého neutralytu.The essence of the apparatus for the preparation of the subject electrolyte is that it consists of a frame in which the upper cylinder rotatably mounted and the piston-coated lower cylinder and the upper cylinder abut the lower cylinder, which is located in the lower part of the latter. an electrolyte tray, wherein the upper cylinder is provided on one side with a drive and on the other side is provided with a contact for connecting the positive terminal of the source and the lower cylinder provided with a contact for connecting the negative pole of the source. The advantage of the electrolyte according to the invention is that less raw materials are needed to produce the electrolyte, both in poultry and in quantity, while the raw materials are readily available and cheaper. Another advantage of this is that the vapors produced by it do not cause health problems. The production costs of the electrolyte according to the invention are many times lower than the electrolyte used so far. A further advantage of the electrolyte according to the invention is that the sheets coated with it can be neutralized with a solution of 50 ml of water in 950 ml of water, thereby avoiding the need for expensive neutrality.
Na pripojenom výkrese na obr. 1 je zná-zorněné zariadenie na vykonáváme sposobupřípravy elektrolytu podlá vynálezu. V 950 ml vody sa rozpustí 0,3 až 0,4 gramudvojchromanu draselného, potom sa prileje50 ml 31 až 32 %-nej kyseliny chlorovodíko-vej. Po zmiešaní týchto zložiek vznikne e-lektrolyt, ktorého vlastnosti třeba ešte u-praviť působením elektrického prúdu na za-riadení podlá obr. 1.In the accompanying drawing, Fig. 1 shows a device for carrying out the electrolyte preparation according to the invention. 0.3 to 0.4 gram of potassium bischromate are dissolved in 950 ml of water, then 50 ml of 31-32% hydrochloric acid are added. Upon mixing of these components, an electrolyte is produced, the properties of which still need to be corrected by applying an electric current to the device according to FIG.
Do misky 1 pre elektrolyt sa naleje toíkoelektrolytu na spracovanie, aby v ňom bolčiastočne ponořený dolný válec 2, ktorý jepotiahnutý pistou. Na horný válec 3 cez kon-takt 6 a na dolný válec 2 cez kontakt 7 sapřipojí zdroj jednosměrného elektrickéhoprúdu o napatí 12 až 18 V a intenzitě 8 až13 A.The electrolyte dish 1 is filled with as much electrolyte for processing as to partially submerge the lower cylinder 2 which is covered by the piston. An unidirectional electric current source 12 to 18 V and an intensity of 8 to 13 A is connected to the upper cylinder 3 via contact 6 and to the lower cylinder 2 via a contact 7.
Otáčaním horného valca 3 pomocou po-honu 4 sa otáča aj dolný válec 2 a všetokelektrolyt sa postupné pomocou plsti nadolnom válci 2 dostává medzi obidva válce,kde uzatvára prúdookruh a vracia sa spaťdo misky. Po 6 až 8 minútach práce na za-riadení je elektrolyt dostatečné spracova-ný. Hotový elektrolyt po precedení cez pa-pierovú vatu je priezračná tekutina zelenejfarby a nevýraznej vůně.By rotating the upper cylinder 3 by means of the drive 4, the lower cylinder 2 is also rotated, and the electrolyte is gradually transferred to the cylinder by means of a felt cylinder 2, where it closes the flow and returns to the bowl. After 6 to 8 minutes of working on the equipment, the electrolyte is sufficiently processed. The finished electrolyte after overcoat through the cotton wool is a clear liquid of green color and a faint odor.
Vynález je možné využívat vo vedecko--výskumných ústavoch a vo výrobných pod-nikoch, ktoré sa zaoberajú tvárněním ple-chov.The invention can be used in scientific research institutes and in manufacturing plants that are engaged in the shaping of pleura.
