Description
Przedmiotem wynalazku jest kolek rozprezny, sluzacy do laczenia przedmiotów, uniemozliwiajac ich przesuniecie w kierunku prostopadlym do osi kolka.The subject of the invention is an expansion set, used to connect objects, preventing them displacement perpendicular to the axis of the pin.
Znane sa konstrukcje kolków sprezystych rurowych z rozcieciem wzdluz pobocznicy walca, równoleglym do osi kolka. Kolki takiej konstrukcji wykonywane sa z stalowego preta okraglego droga obróbki skrawaniem a nastepnie sa obrabiane cieplnie. Wada tak wykonywanych kolków jest duza pracochlonnosc i materialochlon¬ nosc oraz mala sprezystosc ze wzgledu na niekorzystny uklad wlókien. Kolki sprezyste sa równiez wykonywane przez zwijanie z prostokatnych kawalków blachy stalowej,lecz ze wzgledu na maly stosunek srednicy kolka do grubosci blachy nie ma mozliwosci dogiecia krawedzi blachy tworzacych brzegi szczeliny kolka, przez co kolek nie dolega calym obwodem do pobocznicy otworu laczonych elementów. Tak wykonane kolki nie zapewniaja polaczenia odpowiedniej jakosci.There are known designs of tubular spring pins with a cut along the side of the cylinder, parallel to the axis of the spike. The spikes of such a structure are made of a steel round bar with a machining path and then they are heat treated. The disadvantage of such made cols is their high labor consumption and material consumption bearing capacity and low elasticity due to the unfavorable arrangement of fibers. Spring pricks are also performed by rolling from rectangular pieces of steel sheet, but because of the small ratio the diameter of the pin to the thickness of the sheet, it is not possible to bend the sheet edges forming the edges of the slot colic, so that the entire circumference of the colon does not stick to the side of the opening of the connected elements. So made the colic does not provide the proper quality connection.
Polepszenia wlasnosci mechanicznych kolka sprezystego oraz poprawienia jego technologicznosci, wedlug wynalazku, uzyskuje sie dzieki temu, ze kolek sprezysty zwiniety z blachy stalowej posiada na pobocznicy walca szczeline uksztaltowana w formie kata rozwartego, którego dwusieczna kata lezy w plaszczyznie prostopadlej do osi kolka a wierzcholek kata rozwartego szczeliny wykonany jest promieniem, przy czym najkorzystniej jest gdy kat wierzcholkowy jest w przedziale 170—120°.Improving the mechanical properties of the spring pin and improving its technological properties, according to of the invention, is obtained thanks to the fact that the spring collet coiled from a steel sheet has on the side of the cylinder a fissure formed in the form of an obtuse angle, with the bisector of the angle lying in the plane perpendicular to the axis of the pin and the apex of the obtuse angle of the slot is radius, most preferably being when the vertex angle is in the range 170-120 °.
Zaleta kolka sprezystego wedlug wynalazku jest latwosc wykonania kolka o dokladnym przekroju kolowym na drodze obróbki plastycznej na zimno, przy prawie calkowitym wykorzystaniu materialu.The advantage of the spring pin according to the invention is that it is easy to make a pin with an exact cross section by cold working with almost all material utilization.
Przedmiot wynalazku jest uwidoczniony w przykladowym wykonaniu na rysunku, na którym fig. 1 przedstawia kolek sprezysty w rzucie glównym, fig. 2 ten sam kolek w rzucie z góry.The subject of the invention is shown in an exemplary embodiment in the drawing in which Fig. 1 shows the spring colon in a main view, fig. 2 the same col in a top view.
Jak uwidoczniono na rysunku, kolek sprezysty zwiniety jest z blachy stalowej i posiada na pobocznicy walca 1 szczeline 2 uksztaltowana w formie kata rozwartego, którego dwusieczna kata lezy w plaszczyznie prostopadlej do osi kolka a wierzcholek 3 kata rozwartego, szczeliny 2 wykonany jest promieniem.As shown in the drawing, the spring collet is coiled from a steel sheet and has a side surface cylinder 1 slot 2 in the form of an obtuse angle, with the bisector of the angle lying in the plane perpendicular to the axis of the pin and the apex 3 of the obtuse angle, the slot 2 is made with a radius.
Przykladem zastosowania kolka sprezystego wedlug wynalazku jest polaczenie w stojaku hydraulicznym lypu SHC 40 koronki z rura przedluzacza, oraz rury przedluzacza z rdzennikiem.2 89 950An example of the use of a spring pin according to the invention is a connection in a hydraulic stand SHC 40 lypu lace with extension tube and extension tube with core box. 2 89 950
