Description

W znanych dotychczas sposobach do¬ prowadzania przedmiotów obrabianych do tloczni-ciagarek lub t. p. przedmioty te badz to bywaja podsuwane do stempla (przetloka) ciagnacego recznie, w pew¬ nych okolicznosciach przy uzyciu równi pochylej, badz tez stosowano samoczyn¬ ne urzadzenia pomocnicze, sprzezone, z maszyna, a zatem takie, które musialy pracowac w jednakowem tempie (wraz) ze stemplem. Wszystkie te urzadzenia posiadaja jednak te wade, iz zaleza od zrecznosci lub wprawy robotnika, ponie¬ waz w wypadku pierwszym, przy wy¬ lacznie recznem doprowadzaniu, robotnik prócz tej pracy,musi wykonywac i inne je¬ szcze czynnosci, a zatem nie jest w sta¬ nie zawsze w swoim czasie sledzic za pod¬ suwaniem materjalu; w wypadku drugim zrecznosc robotnika gra jeszcze wieksza role, gdyz musi on byc bardzo wprawny, azeby zaladowac otwory organu dopro¬ wadzajacego, pracujacego w jednakowem tempie ze stemplem ciagnacym, w takich samych okresach czasu. Wymienione wa¬ dy maja ten skutek, iz stempel ciagnacy czesto pracuje jalowo, co obniza spraw¬ nosc maszyny. Azeby zaradzic tym bra¬ kom, przedmioty obrabiane zostaja, zgod¬ nie z niniejszym wynalazkiem, utrzymane miedzy dwiema scianami kanalu dopro¬ wadzajacego, z których jedna lub obie po¬ ruszaja sie w ten sposób, iz przedmioty obrabiane zostaja wprowadzane w ruch skierowany ku stemlowi ciagnacemu.Rysunek wykazuje schematycznie, w postaci pzykladu, sposób wykonania wy¬ nalazku.Zboku stempla ciagnacego a biegnie na dwu kolach b, c, napedzanych przez ma¬ szyne , najwlasciwiej elastyczna tasma bez konca d. Druga sciana kanalu, dopro¬ wadzajacego przedmioty obrabiane, jest utworzona przez szyne e, która (jak na rysunku) moze byc uksztaltowana jako ramie, osadzone obrotowo obok stempla ciagnacego i naciskane recznie, lub zapo- moca sprezyny, ku tasmie d. Strona tasmy d, zwrócona ku przedmiotowi obrabiane¬ mu, posuwa sie w kierunku stempla stale z wieksza, niz on szybkoscia,podczas gdy z drugiej strony przedmiot obrabiany jest przyciskany zapomoca szyny e, do ta¬ smy d. Wsutek tarcia przedmiot obrabia¬ ny zostaje wprawiany w ruch po szynie, w kierunku stempla ciagnionego. Urza¬ dzenie to posiada te wielka zalete, iz ro¬ botnik nie potrzebuje zupelnie uwazac na to, czy przedmiot obrabiany jest zalo¬ zony dokladnie prosto, gdyz skutkiem dzialania poruszajacej sie tasmy, jak rów¬ niez skutkiem wytwarzajacego sie tarcia, wzglednie prowadzenia wzdluz prostych powierzchni, przedmiot obrabiany, który bywa najczesciej cylindryczny, prostuje sie samoczynnie przez toczenie sie, wywo¬ lane zapomoca tasmy.Szyna e moze byc stala, przyczem ta¬ sma musi byc tak osadzona, aby miedzy nia a przedmiotem obrabianym zostalo wy¬ wolane niezbedne tarcie; szyna e moze byc równiez uksztaltowana, jako element suwny, znajdujacy sie pod dzialaniem sprezyny, który przyciska samoczynnie przedmiot obrabiany do tasmy przesuwa¬ jacej d.Moga byc równiez zastosowane dwie tasmy przesuwajace, które utrzymuja przedmioty obrabiane i z których jedna posuwa sie z wieksza szybkoscia, niz dru¬ ga, wywolujac ruch toczny przedmiotu obrabianego. PL PLIn the hitherto known methods of feeding the workpieces to the press-drafts or the like, these items or the like are fed to the drawing punch by hand, in some circumstances using an inclined plane, or automatic auxiliary devices connected, with the machine, and therefore those that had to work at the same pace (along with) the stamp. All these devices, however, have the disadvantage that they depend on the skill or skill of the worker, because in the first case, with only manual feeding, the worker, apart from this work, has to perform other activities, and therefore is not able to ¬ not always keep track of material advancement in due course; in the latter case, the skill of the worker plays an even greater role, since he must be very skilled in order to load the holes of a feeder organ, working at the same pace with a pull punch, at the same time. The above-mentioned defects have the consequence that the pull ram is often idle, which reduces the efficiency of the machine. To remedy these shortcomings, workpieces are, in accordance with the present invention, held between two walls of a feeder channel, one or both of which move so that the workpieces are moved towards the punch. The drawing shows schematically, in the form of an example, the method of implementing the invention. The side of the drawing punch a runs on two wheels b, c, driven by machines, the most flexible belt without end d. The second channel wall, leading to the workpieces , is formed by a rail e which (as shown) can be shaped as a frame, rotatably mounted next to the pull die and pressed by hand, or by a spring, towards the tape d. The side of the tape d facing the workpiece advances in the direction of the punch is constantly faster than it, while on the other side the workpiece is pressed against the rail e against the tape d. the workpieces are set in motion along the rail towards the drawn punch. This device has the great advantage that the worker does not need to be careful about whether the workpiece is placed exactly straight, as a result of the action of the moving belt as well as of the friction generated, or of guiding along straight lines. the surface, the workpiece, which is usually cylindrical, straightens itself by rolling, caused by the use of a tape. The rail may be fixed, so that the tape must be embedded in such a way that the necessary friction is generated between it and the workpiece. ; the rail can also be shaped as a sliding element, under the action of a spring that presses the workpiece automatically against the sliding belt d. Two sliding belts can also be used to hold the workpieces and one of which moves at greater speed. than the other, causing the workpiece to roll. PL PL
