Description

Przedmiotem wynalazku jest sposób zwiekszania przeswitu tasm perforowanych w zastosowaniu do produkcji pasemek na plyty dla akumulatorów za¬ sadowych.Dotychczas proces perforacji prowadzi sie na spe¬ cjalnych urzadzeniach metoda iglowa lub krazko¬ wa. Proces ten polega na przebiciu z jednej strony tasmy otworów w ustalqnej podzialce wzdluznej i poprzecznej. Po procesie perforacji przebita po¬ wierzchnia blachy zostaje przetloczona pozosta¬ wiajac na swej powierzchni postrzepione za¬ dziory.W trakcie dalszego procesu technologicznego pro¬ dukcji gotowych pasemek to jest po wypelnieniu masa aktywna pasemka dolnego i zalozeniu pasem¬ ka górnego oraz po zlozeniu gotowych pasemek w plyty powstale po operacji przetlaczania zadziory zaprasowuje sie na walcarkach deseniarki w wyniku czego czesc ich wraca do pozycji pierwotnej. Znane sa równiez sposoby polegajace na zwiekszeniu prze¬ switu po perforacji tasm za pomoca szlifowania za¬ dziorów, lub oparte na systemie reperforacji to jest powtórnego przebijania otworów. Proces ten jest równiez poprzedzany zabiegiem wstepnego szlifo¬ wania zadziorów oraz wyzarzaniem tasmy.Istota rozwiazania wedlug sposobu jest reperfo- racja polegajaca na powtórnym wprowadzeniu w istniejace juz otwory w tasmie perforowanej na¬ rzedzia perforujacego z tym, ze od strony przeciw¬ nej to jest od strony powstalych zadziorów. System 10 15 20 25 30 ten pozwala na zwiekszenie przeswitu przez roz¬ giecie istniejacych po perforacji zadziorów na cze¬ sciowe skalibrowanie otworów w tasmie. Wykona¬ na tym sposobem tasma nie zmienia swego pierwot¬ nego przeswitu nawet pod wplywem bezposrednie¬ go sprasowania. Proces reperforacji prowadzi sie na tym samym urzadzeniu za pomoca narzedzia w po¬ staci metalowej rolki walcowej z nacietymi zebami wspólpracujacej z rolka podtrzymujaca w postaci krazka z nacietymi na nim rowkami o podzialce ró¬ wnej podzialce nacietych zebów, usytuowanymi ró¬ wnolegle do osi glównej rolek.W odniesieniu do dotychczasowego stanu techniki sposób wedlug wynalazku posiada zalety polegajace na zwiekszeniu przeswitu tasm w pasemkach czego wynikiem sa efekty w postaci wzrostu jakosci aku¬ mulatorów przeznaczonych zwlaszcza do poboru du¬ zych pradów. Zaleta jest równiez obnizenie praco¬ chlonnosci i energochlonnosci pomocniczych proce¬ sów technologicznych droga eliminowania operacji szlifowania i wyzarzania.Przedmiot wynalazku zostal uwidoczniony na ry¬ sunku, na którym fig. 1 — przedstawia schematycz¬ ne rozmieszczenie narzedzi w urzadzeniu do perfo¬ rowania tasm, fig. 2—zab rolki perforacyjnej w ze¬ stawieniu z fragmentem wycietej tasmy, a fig. 3 — rozgiecie powstalych w trakcie perforacji zadzio¬ rów przez zab rolki reperforacyjnej.Proces reperforacji tasmy prowadzi sie na tym sa¬ mym urzadzeniu co perforacji i tym samym narze- U? 2}6112216 3 4 dziem to jest rolka perforacyjna w postaci krazka posiadajacego na pobocznicy uzebienie iglowe. Po¬ szczególne narzedzia na urzadzeniu tak sie rozmie¬ szcza, aby najpierw odbywala sie perforacja przy pomocy rolki perforacyjnej 1, do której tasme 2 do¬ ciska rolka dociskowa 3 wykonana jako krazek po¬ siadajacy na pobocznicy rowki odlegle od siebie w tej samej podzialce co podzialka rozstawienia ze¬ bów na rolce perforacyjnej. Nastepnie prowadzi sie proces reperforacji, w którym narzedzia to jest rol¬ ka reperforacyjna 4 i rolka podtrzymujaca 5 sa ustawione odwrotnie w stosunku do tasmy 2 jak w procesie perforacji. 10 Zastrzezenie patentowe Sposób zwiekszania przeswitu tasm perforowa¬ nych w wyniku reperforacji, znamienny tym, ze bezposrednio po wykonaniu perforacji tasme podaje sie na tym samym urzadzeniu zabiegowi reperfora¬ cji, przy czym zabieg ten wykonuje sie z przeciwnej strony tasmy za pomoca narzedzia w postaci meta¬ lowej rolki walcowej z nacietymi zebami to jest rolki reperforacyjnej wspólpracujacej z rolka pod¬ trzymujaca w postaci krazka z nacietymi na nim rowkami o podzialce równej podzialce nacietych zebów, usytuowanymi równolegle do osi glównej rolek.Fig.1 Fig.2 ZGK 0949/1110/81 — 120 szt.Cena zl 45,— PLThe subject of the invention is a method of increasing the clearance of perforated tapes for use in the production of strips for plates for basic batteries. Hitherto, the perforation process is carried out on special devices using the needle or disc method. This process consists in punching, on one side, a strip of holes in a fixed longitudinal and transverse scale. After the perforation process, the punctured surface of the sheet is embossed, leaving frayed holes on its surface. During the further technological process of producing ready-made strands, that is, after filling the active mass of the lower strand, placing the upper strand and folding the finished strands. in the boards, the burrs are pressed on the rolling mills, as a result of which some of them return to their original position. There are also known methods consisting in increasing the clearance after the perforation of the strips by grinding the barbs, or based on a system of perforation, that is, the re-punching of holes. This process is also preceded by preliminary grinding of the burrs and annealing of the tape. The essence of the solution according to the method is the re-perforation consisting in re-inserting the perforating tool into the existing holes in the belt of the perforating tool, with the opposite side being from side of burrs. This system makes it possible to increase the clearance by extending the burrs after the perforation to partially calibrate the holes in the strip. The tape produced in this way does not change its original clearance, even under the influence of direct compression. The repair process is carried out on the same device by means of a tool in the form of a metal cylindrical roller with notched teeth cooperating with a supporting roller in the form of a disc with grooves cut on it with a different pitch of notched teeth, located parallel to the main axis of the rollers In relation to the prior art, the method according to the invention has the advantages of increasing the shifting of the strips in the strands, which results in the effects of increasing the quality of batteries intended, in particular, for the consumption of high currents. The advantage is also the reduction of the labor and energy consumption of auxiliary technological processes by eliminating the grinding and annealing operations. The subject of the invention is shown in the drawing, in which Fig. 1 - shows a schematic arrangement of the tools in the machine for perforation of tapes, Fig. 2 - the perforation roller in relation to a fragment of the cut tape, and Fig. 3 - the bending of the burrs formed during the perforation through the perforation roller tab. The process of re-perforation of the tape is carried out on the same device as the perforation and the same na- U? 2} 6112216 3 4 This is a perforation roller in the form of a disc with a needle tooth on the side surface. The individual tools on the device are arranged in such a way that first a perforation takes place by means of a perforating roller 1, against which the belt 2 is pressed by a pressure roller 3 made as a disc that sits on the side of the grooves at a distance from each other in the same scale as tooth spacing on the perforation roller. The re-perforation process is then carried out in which the tools, i.e. the re-perforation roller 4 and the supporting roller 5, are oriented opposite to the belt 2 as in the perforation process. A method of increasing the clearance of perforated tapes as a result of reperforation, characterized in that, immediately after the perforation is made, the tape is fed on the same device to the re-perforation procedure, whereby this procedure is performed on the opposite side of the tape by means of a meta-tool. A circular cylindrical roller with notched teeth, i.e. a repair roller cooperating with a supporting roller in the form of a disc with grooves cut on it with a pitch equal to the pitch of notched teeth, located parallel to the main axis of the rollers.
