Description

Przedmiotem wynalazku jest prostarka skosnorol¬ kowa do rur metalowych, pracujaca pojedynczo lub w linJii automatycznej.The subject of the invention is a skewerol straightener tool for metal pipes, working individually or in the automatic line.

Stosowane w technice rury metalowe, przed ich zainstalowaniem musza byc uprzednio wyprostowa- 5 ne. Wynika to stad, ze w procesie produkcji, rury przechodza przez rózne zakresy temperatur, które wywoluja deformacje ksztaltu, zwlaszcza prostoli- niowosci, 00 uniemozliwialoby lich zastosowanie zgo¬ dnie z przeznaczeniem. 10 Znana w technice, na przyklad z opisu patentowego PRL 76 269 prostarka skosnorolkowa sluzaca do pro¬ stowania rur metalowych wyposazona jest w nape¬ dzane obrotowo rolki robocze o ksztalcie hiperbo- lotidy obrotowej, umieszczone w dwóch poziomych 15 rzedach — dolnym i górnym oraz polozone ukosnie do kierunku prostowania. Rolki znajdujace sie w górnym rzedzie umieszczone sa naprzeciw odstepów istniejacych pomiedzy rolkami dolnego rzedu li sa pionowo nastawne celem mozliwosci regulacji wiel- 20 kosci przeswitu zaleznego od srednic prostowanych rur. Niedogodnoscia stosowania prostarkii o opisanej konstrukcji jest to, ze mozna na niej prostowac je¬ dynie rury lub prety majace na calej swojej dlu¬ gosci jednakowasrednice. 25 W praktyce bardzo czesto istnieje koniecznosc sto¬ sowania rur majacych, na jednym lub obu kon¬ cach, odsadzenie w postaci kielicha.Metal pipes used in the technique, before them installation, they must be straightened - 5 ne. This is due to the fact that in the production process, pipes pass through the different temperature ranges that cause deformation of the shape, especially rectangular inferiority, 00 would make it impossible to apply deadly days with destiny. 10 Known in the art, for example from the patent specification PRL 76 269 Twist-roll straightener for pro for the use of metal pipes is equipped with a filling device rotationally knitted work rollers in the shape of hyperbo- Rotary lottery, placed in two horizontal 15 the rows - bottom and top, and diagonally to the straightening direction. Rollers located in the top row is placed opposite the gaps existing between the rollers of the lower row of leaves are vertically adjustable to allow for adjustment of figures 20 clearance bone depending on the rectified diameters pipes. A disadvantage of using a straightener as described construction is that you can straighten them on it pumpkins, pipes or rods with their entire length guests have the same diameter. 25 In practice, it is very often necessary to have a table the use of pipes having one or both ends cach, weaning in the form of a cup.

Celem wynalazku jest usuniecie tej niedogodno¬ sci, a zagadnieniem technicznym wymagajacym roz- 30 wiazania dla osiagniecia tego celu jest opracowanie konstrukcji prostarki skosnorolkowej, która moglaby prostowac rury majace stala srednice na calej swo¬ jej dlugosci, prety oraz rury z odsadzeniem naj¬ czesciej w postaci kielichów.The object of the invention is to overcome this disadvantage sci, and a technical issue requiring more than 30 Binding to achieve this goal is to develop design of a twist-roll straightener that could straighten pipes having a constant diameter over the entire bolt its lengths, bars and pipes with an offset of the rent more often in the form of goblets.

Zgodnie z wynalazkiem, zagadnienie to zostalo rozwiazane dzieki temu, ze znana prostarka skosno¬ rolkowa ma rolki napedzane umieszczone w jednym rzedzie, korzystnie w dolnym oraz rolki nienapedza- ne umieszczone w drugim rzedzie, przy czym czesc rolek nienapedzanych umieszczona jest bezposrednio nad rolkami napedzanymi, jest pionowo uchylna i wspólpracuje z fotokomórkami, a pozostala czesc rolek nienapedzanych umieszczona jest nad odste¬ pami istniejacymi pomiedzy rolkami napedzanymi i jest pionowo nieuchylna.According to the invention, this problem remains solved due to the fact that the known oblique straightener roller has driven rollers placed in one the row, preferably in the lower row, and the rollers without ne placed in the second row, being part the non-driven rollers are placed directly above the driven rollers, it is vertically tilting and it works with photocells, and the rest of the non-driven rollers is located above the gap the memory between the driven rollers and is vertically invisible.

Tak rozwiazane zagadnienie techniczne sprawia, ze prostarka moze byc stosowana do prostowania rur gladkich, pretów oraz rur z odsadzeniami, co do¬ tychczas bylo nieosiagalne.A technical problem solved in this way makes the straightener can be used to straighten pipes smooth, rods and pipes with shoulders, as for it was unavailable then.

Przedmiot wynalazku jest uwidoczniony w przy¬ kladzie wykonania na rysunku, na którym fig .1 przedstawia prostarke skosnorolkowa w widoku czo¬ lowym, a fig. 2 — prostarke w widoku z góry- Jak pokazano na fig. 1 i 2, prostarka wyposazona jest w robocze rolki 1 o ksztalcie hiperboloidy obro¬ towej, napedzane obrotowo i pionowo nieuchylne, umieszczone w rzedzie dolnym oraz w nienapedzane rolki 2 pionowo uchylne i nienapedzane rolki S pio¬ nowo nieuchylne, umieszczone w rzedzie górnym. 95 33995 339 3 Rolki 2 znajduja sie bezposrednio nad rolkami 1, a rolki 3 umieszczone sa nad odstepami istniejacymi pomiedzy rolkami 1. W rzedzie dolnym umieszczone sa fotokomórki 4 wspólpracujace z silownikami 5 sluzacymi do pionowego przemieszczania rolek 2.The subject matter of the invention is illustrated in example the embodiment in the drawing in which fig. 1 shows a crosspiece in front view Fig. 2 is a straightener in top view As shown in Figs. 1 and 2, a straightener is provided it is in working rollers 1 in the shape of a hyperboloid rotation towa, driven in rotation and vertically non-tilting, placed in the lower row and not driven rollers 2 vertically swiveling and not driven rollers S vertical newly inevitable, placed in the upper row. 95 33 995 339 3 The rollers 2 are located directly above the rollers 1, and the rollers 3 are placed over the existing gaps between the rollers 1. Positioned in the lower row there are 4 photocells cooperating with actuators 5 for the vertical movement of the rollers 2.

Prostarka opisana w przykladzie wykonania dzia¬ la nastepujaco: rury gladkie, prety lub rury kieli¬ chowe, które maja byc prostowane, doprowadzane sa do prostarki za pomoca samotoku. Prostarka jest go¬ towa do pracy w chwili, gdy obie nienapedzane, pio¬ nowo uchylne rolki 2 sa podniesione. Samotok prze¬ mieszcza rure na pierwsza rolke napedzana 1, wów¬ czas fotokomórka 4 znajdujaca sie w poblizu wejscia do prostarki wysyla impuls do silownika pneumaty¬ cznego 5, powodujac opuszczenie rolki nienapedza- nej 2 az do wywolania okreslonego nacisku na rure, co powoduje jej wciaganie w glab prostarki W dal¬ szym eiagu rura przechodzi pod pionowo nieuchylna rólke 3, która powoduje jej przeginanie — prosto¬ wanie i z chwila, gdy rura znajdzie sie nad druga napedzana rolka 1, fotokomórka 4 umieszczona w poblizu wyjscia z prostarki uruchamia silownik 5, który opuszcza kolejna, pionowo uchylna rolke 2, celem wywolania odpowiedniego nacisku konieczne¬ go do dalszego przemieszczenia rury przez prostarke.The straightener described in the example of the gun embodiment as follows: smooth pipes, bars or sockets Retractions to be straightened are brought in to the straightener using the roller table. The straightener is easy to work when both were not driven, the new swivel rollers 2 are raised. The loneliness of the accommodates the tube for the first driven roller 1, ie time photocell 4 located near the entrance sends a pulse to the straightener to the pneumatic actuator 5, lowering the roller without the n 2 until a certain pressure is put on the pipes, which causes it to be drawn into the straightener into the distance the second pipe goes under the vertically invisible roll 3, which causes it to bend - straight when the pipe is above the other driven roll 1, photocell 4 located in near the outlet of the rectifier, it starts the actuator 5, which leaves another, vertically tilting roller 2, necessary in order to apply the appropriate pressure it to move the pipe further through the straightener.

Z chwila przejsdila rury przez prostarke, rolki 2 sa¬ moczynnie sie podnosza i prostarka jest gotowa do przyjecia nastepnej rury.After a while, the pipes passed through the straightener, the rolls 2 sa¬ rises sharply and the straightener is ready for receiving the next pipe.
