Description

Przedmiotem wynalazku jest urzadzenie do odksztalcania elementów zwlaszcza laczników otwartych cie¬ gien lancuchowych.Stan wstepnego naprezania laczników otwartych stosowanych powszechnie jako zamki boczne górniczych przenosników zgrzeblowych uzyskuje sie w wyniku wstepnego naprezania tych laczników przy pomocy maszy¬ ny wytrzymalosciowej, prasy hydraulicznej lub urzadzen do kalibrowania lancuchów. Stosowanie tych urzadzen do wstepnego naprezania nie zapewnia powtarzalnosci wyników i jest malo wydajne.Urzadzenie do odksztalcania elementów zwlaszcza laczników otwartych ciegien lancuchowych wedlug wynalazku posiada mimosrodowa krzywke wspólpracujaca z co najmniej jedna rolka ulozyskowana w dzwigni, która to wykonuje ruch wahadlowy wokól przegubu. Koniec dzwigni wyposazony jest w element chwytowy przekazujacy sile napinajaca na lacznik.Urzadzenie wedlug wynalazku umozliwia wywolanie odpowiedniego stanu naprezen wstepnych poprzez plastyczne odksztalcenie laczników, których jedyne konce sa unieruchomione, a na drugie dziala odpowiednio dobrana sila napinajaca.Urzadzenie wedlug wynalazku odznacza sie prostota i malym zuzyciem energii oraz pracuje z duza wydaj¬ noscia przy zachowaniu powtarzalnosci warunków zabiegu napinania.Urzadzenie do odksztalcania elementów zwlaszcza laczników otwartych ciegien lancuchowych pokazane jest w przykladzie wykonania na rysunku, na którym fig. 1 przedstawia widok urzadzenia z boku, a fig. 2 widok urzadzenia z góry.Urzadzenie wedlug wynalazku posiada poruszajaca sie ruchem obrotowym krzywke mimosrodowa 1, która wspólpracuje z krzywkami 3 lozyskowymi w wahliwych dzwigniach 2 wykonujacych ruch wahadlowy wokól przegubów 4. Konce dzwigni wyposazone sa w elementy chwytowe 8 przekazujace sile napinajaca Pnap na jeden z konców lacznika otwartego 5. Drugi koniec lacznika ustalony jest w wyniku oparcia go o element oporowy 7.W chwili, gdy jeden lacznik 5 poddawany jest odksztalceniu nastepowac moze nakladanie drugiego lacznika 6, który bedzie poddany odksztalceniu po obróceniu sie krzywki 1 o kat 180°.2 96112 PLThe subject of the invention is a device for deforming elements, especially open connectors of chain strings. The state of prestressing of open fasteners commonly used as side locks of mining belt conveyors is obtained as a result of initial tensioning of these connectors by means of a testing machine, hydraulic press or calibrating devices. . The use of these pretensioning devices does not ensure the reproducibility of the results and is inefficient. The device for deforming elements, especially open chain links according to the invention, has an eccentric cam cooperating with at least one roller located in the lever, which performs a swinging movement around the joint. The end of the lever is equipped with a gripping element transmitting the tensioning force to the fastener. The device according to the invention enables the induction of an appropriate state of initial stresses by plastic deformation of the fasteners, the only ends of which are immobilized and the other is subjected to a properly selected tensioning force. The device for deforming elements, especially open chain links, is shown in the example of the embodiment in the drawing, in which Fig. 1 shows a side view of the device, and Fig. 2 a view of the device. The device according to the invention has a rotating eccentric cam 1, which cooperates with 3-bearing cams in oscillating levers 2 that swing around the joints 4. The ends of the lever are equipped with gripping elements 8 transmitting the tensioning force Pna p on one of the ends of the open connector 5. The other end of the connector is fixed by leaning it against the stop element 7. When one connector 5 is subjected to deformation, the second connector 6 may be placed, which will be deformed after turning the cam 1 by 180 ° angle. 2 96112 PL
