The advantage of the device according to the invention is the possibility of quick and very precise adjustment of the lateral clearance between the forming segments without significant demands on the operator's skill. It is particularly advantageous when gaps are formed between the wedge surfaces of both wedges and the support surfaces of both parts of the clutch disc, filled with sliding bodies in the form of cylindrical sections. In this case, in each position of the radial displacement of the pair of wedges, the force from the torque is favorably distributed over relatively large areas, which makes the clutch capable of transmitting relatively large torques.

Description

Vynález sa týká zariadenia pre nastavovanie bočnej včle medzi tvárniacimi segmentmi, vhodného najma pre stroje na priečne profilovanie plechov, ktoré zariadenie je tvořené systémom spojok pre aspoň dva paralelné usporiadané hnané hriadele a aspoň dva, pomocou prevodovej skrine synchronizované hnacie hriadele.BACKGROUND OF THE INVENTION The present invention relates to a device for adjusting a side bee between forming segments, particularly suitable for sheet metal profiling machines, comprising a clutch system for at least two parallel driving shafts and at least two transmission shafts synchronized by a gearbox.

Podlá súčasného stavu techniky sa bočná vola medzi tvárniacimi segmentmi nastavuje uvolněním jednej z tuhých spojok, pričom sa tvárniaci segment pokusné nastavuje do správnej polohy. Nevýhodou takýchto zariadení je, že si vyžadujú zručnú obsluhu, zdlhavý postup, pričom výsledná přesnost vzájomného nastavenia tvárniacich segmentov nie je vždy dostatočná»According to the state of the art, the side call between the mold segments is adjusted by releasing one of the rigid couplings, the mold segment being tentatively adjusted to the correct position. The disadvantage of such devices is that they require skillful operation, a lengthy procedure, and the resulting accuracy of the alignment of the forming segments is not always sufficient »

Tieto nevýhody v znaČnej miere odstraňuje zariadenie pre nastavenia boč-nej vole medzi tvárniacimi segmentmi podlá vynálezu, ktorého podstata spočívá v tom, že aspoň jedna spojka spojkového systému tohto'zariadenia má jeden z jej spojkových kotúcov deleriý vo dvoch navzájom paralelných radíálnych rovinách a jednej axiálnej rovině na dve časti, medzi ktoré sú v tejto axiálnej rovině vložené dva radiálně výsuvné, avšak s pevnou vzájomnou vzdialenostou proti sebe, usporiadané klíny.These drawbacks are largely eliminated by the sidebar adjustment device between the forming segments of the present invention, wherein at least one clutch of the clutch system of the apparatus has one of its clutch discs in two parallel radial planes and one axial plane A wedge is arranged in a plane on two parts between which two radially extending but fixedly spaced apart ones are inserted in this axial plane.

Výhodou zariadenia podlá vynálezu je možnost rychlého a velmi přesného nastavenia bočnej vole medzi tvárriiacimi segmentmi bez osohitných nárokov na zručnost obsluhy. Obzvlášt je výhod né, keď medzi klínovými plochami obidvoch klinov a opěrnými plochami obidvoch častí spojkového kotúča sú vytvořené medzery vyplněné klznými telieskarai v podobě válcových úsečí. V tom případe sa v každej polohe radiálneho presunutia dvojice klinov priaznivo rozloží sila z krútiaceho momentu na relativné velké plochy, čím je spojka sposobila prenášat i relativné velké krútiace momenty.An advantage of the device according to the invention is the possibility of fast and very precise adjustment of the lateral clearance between the forming segments without the need for operator skill. It is particularly advantageous if gaps are formed between the wedge surfaces of the two wedges and the abutment surfaces of the two parts of the clutch disc, in the form of cylindrical sections. In this case, in each radial displacement position of the wedge pair, the torque force is favorably distributed over relatively large surfaces, thereby causing the clutch to transmit relatively large torques.

V danom případe sú dve spojky tohto. spojkového.· systému vyhotovené tak, že jeden ich spojkový kotúČ je delený vo dvoch navzájom rovnoběžných radiálnych rovinách 23, 24 a jednej axiálnej rovině 25 na dva časti 10, 1 3, medzi ktoré sú v tejto axiálnej rovině 25 vložené dva proti sebe usporiadané klíny 1 6, 17 /obr. 3/ upnuté na obidvoch koncoch skrutkovej tyče £5, opatrenej v jej strednej časti závitom, ktorým je * v radiálnom smere zaskrutkovaná do kovověj maticovéj·vložky.14, vsadenej do dutiny 11 centrovacieho třňa 1 2, vytvořeného na jednej časti 10 spojkového kotúča, takže skrutková tyč 1 5 je spolu s klinmi 1 6, 17 radiálně výsuvná. Medzi klínovými plochami 18 obidvoch týchto 'klinov 16, 17 a opěrnými plochami £, 20 obidvoch častí 1Q, 13 spojkových kotúčov sú vytvořené medzery, v ktorých sú umiestnené klzné telieska 21 v podobě válcových úsečí, vyhotovené z kalitelnej ocele.The device according to the invention is designed as a mechanical clutch system in which both rigid clutches connect two parallel arranged driven shafts 9 and an upper drive shaft T and a lower drive shaft 6, which are synchronized by a gear housing 6. The driven shaft 9 of the upper forming drum 4 is rotatably mounted in the upper slides 4 and the driven shaft 6 of the lower forming drum 4 is rotatably mounted in the lower slides 4, vertically displaceably disposed in the stand 11 of the profiling machine. In this case there are two couplings of this. The system is designed in such a way that one of their clutch discs is divided in two parallel radial planes 23, 24 and one axial plane 25 into two parts 10, 13, between which two oppositely arranged wedges are inserted in this axial plane 25. 16, 17 / FIG. 3 / clamped on both ends of the screw rod 5 provided with a thread in its central part, which is screwed in a radial direction into a metal nut insert 14, inserted into the cavity 11 of the centering pin 12 formed on one part 10 of the clutch disc, so that the screw rod 15 together with the wedges 16, 17 is radially extensible. Gaps are formed between the wedge surfaces 18 of the two wedges 16, 17 and the abutment surfaces 20, 20 of the two parts 10, 13 of the clutch disks, in which the sliding bodies 21 in the form of cylindrical sections made of hardenable steel are arranged.

Funkcia zariadenia je zřejmá z přiložených obrázkov a vyššie·uvedeného popisu. Uvolněním stahovacích skrutiek 22, ktorými sú na seba dotiahnucé obidvé časti 10, 13 spojkových kotúčov, a pootočením skrutkovej tyče 15 jedným, alebo druhým smerom změní táto v radiálnom smere svoju polohu voči maticovej vložke 14 a pomocou klinov 16, 17 a klzných teliesok 21 umožní bezvčlové uhlové pootočenie jednej časti 10 voči druhej časti 13 spojkového kotúča v požadovanej miere a zároveň výhodné rozloženie sil vyvolaných krútiacim momentom hnacieho hríadela J7, 8_. Tým sa velmi jemným posuvom mQže nastavit aj bočná vola.medzi tvárniacimi segmentmi tvárniacich bubnov j>. Vertikálna vola sa nastavuje změnou polohy dolných šmykadíel a horných -šmykadiel 3». Funkciou dutého centrovacieho trňa12 je vycentrovat jednu část 10 spojkového kotúča voči jeho druhej častí 13.The operation of the device is apparent from the accompanying drawings and the above description. By loosening the tightening bolts 22, which tighten the two clutch disc parts 10, 13, and by turning the screw rod 15 in one direction or the other, the bolt changes its position in the radial direction relative to the nut insert 14 and enables wedges 16, 17 and sliding bodies 21 a torque-free angular rotation of one portion 10 relative to the other portion 13 of the clutch disc to the desired extent and at the same time an advantageous distribution of the forces caused by the torque of the drive shaft 17, 8. As a result, the lateral calls can also be adjusted by means of a very fine feed between the forming segments of the forming drums. The vertical steer is adjusted by changing the position of the lower slides and the upper slides 3 ». The function of the hollow centering mandrel 12 is to center one portion 10 of the clutch disc against the other portion 13.
