Abstract

1513677 Bearing bushes REKTORAT SLOVENSKEJ VYSOKEJ SKOLY TECHNICKEJ 18 July 1975 [29 July 1974] 30153/75 Heading F2A Thin walled bearing bushes are formed from sheet or strip material consisting of a steel base with a low friction coating on one face thereof, the material is of a length equal to the intended circumference of the finished bush plus an additional length, the ends of the strip are bent to a radius equal to that of the desired bush, whilst straight end sections remain at the very ends of the strip, when the length of these straight end sections is greater than 2À5 times the thickness of the steel base at least a part of this excess length is removed so that it no longer exceeds 2À5 times the thickness of the steel base, the strip is then bent on a roll bending device to form a semiproduct which is finally cut to a length equal to that of the circumference of the desired bush to form an open bush which may subsequently be closed.

Description

Vynález sa týká zariadenia na odstraňovanie rovných úsekov tenkostenných ložiskových puzdier.The invention relates to a device for removing straight sections of thin-walled bearing bushes.

Při výrobě ložiskových puzdier najdiležitejšou požiaiavkou je přesné preveienie kruhového prierezu aj v mieste styku zakrúženca, aby puzdro po zalisovani vyhovovalo požadovanej triede přesnosti. KeSže mattriály s klznou vrstvou nie je možné zo strany klznej vrstvy dodatočne upravoval mechanickým obrábaním, je ddležité zakrúžence z týchto mattrialov zhotovovat s vel’kou presnosťou rozmerov, hlavně s ohTadom na predíženie dížky východzieho polotovaru zakružovaním. Týmto probimmom je v túčasnosti věnovaná velká pozornost a ich výskům je rozpracovávaný z ríznych hradísk. t In the production of bearing bushes, the most important requirement is the precise sagging of the circular cross-section, even at the point of contact of the ring, so that the bushing, after pressing, meets the required accuracy class. Since the sliding layer material cannot be retrofitted by mechanical machining on the side of the sliding layer, it is important to make the rings of these mattrials with high dimensional accuracy, especially with a view to extending the length of the initial blank by bending. This probimmom is now a great deal of attention and their heights are elaborated from various dams. T

Sú známe spdsoby a zariadenia na výrobu ložiskových puzdier z mаttriálov s klznou vrstvou, v podstatě ohýbáním v nástrojoch upevněných na lisoch. -Ďalej je známy spísob výroby zakružovaním na zakružovačkách, a to s tromi pracovnými valcami, so štyrmi pracovnými valcami, alebo s dvomi pracovnými valcami, kde jeden válec je potiahnutý eltttiským materiálom. Sú tiež známe Speciálně ztгitdrnit, kde zakrúŽenie pruhu sa realizuje nabalením na pevný válcový trn pomocou jednej, alebo dvoch výkyvných líšt.Methods and devices are known for producing bearing bushes made of material with a sliding layer, essentially by bending in tools mounted on presses. It is further known to produce roll bending on three rollers, four rollers, or two rollers, where one roll is coated with an Eltprint material. It is also known to specialize in which the lacing is performed by wrapping on a rigid cylindrical mandrel by means of one or two pivot bars.

Výroba puzdier v nástrojoch je vhodná predovšetkým pře puzdra malých priemerov od 20 do 60 mm, pričom za max. hranicu možno pokládat priemery od 100 do 120 mm při maximáánej hrúbke ocelového podkladu 2,1 mm a maximálny rozměr dížky puzdra 140 mm. Výroba puzdier na zakružovalkách vyžaduje doplňujúce ztiitienit na spolehlivé vedenie poměrně úzkého pruhu vzhl’adom k zakružovanému priemeru, dostatočnú tuhost a moonost přesného nastavenia. U všetkých týchto splsobov sú nevýhodou a problémom rovné nezakrúžené úseky o řízných dížkach v mieste styku. Vývoj a použitie špeciálnych zariadení, ktorých principy sú v súčasnej době známe, by si na zakružovanie velkorozměrových puzdier vyžadovalo ne.úi^e^j^ne vysoké náklady a čas, čo je zvlášť u шétlsSeiover, alebo kusovej výroby pri širokom rozsahu priemerov i dížok neefektívne. ’The production of tool sleeves is particularly suitable for small diameter sleeves from 20 to 60 mm, with a max. the limit can be laid with diameters from 100 to 120 mm with a maximum steel substrate thickness of 2.1 mm and a maximum housing length of 140 mm. The manufacture of bending sleeves requires additional shading to reliably guide the relatively narrow strip relative to the bending diameter, sufficient rigidity and moonost of accurate alignment. For all these splits, the disadvantage and the problem are the straight, uneven sections of cut lengths at the point of contact. The development and use of special devices, the principles of which are currently known, would require a relatively high cost and time for bending large-sized bushings, especially in the case of wide-ranging or single-piece production over a wide range of diameters and lengths. ineffective. '

Spísob výroby lsiiskových puzdder, hlavně výpočet predíženia východiskového polotovaru je založená na velmi přesných výpočtoch. Ako sa potvrdilo experimennálne, i tak tento spísob nezaručuje často žiadanú přesnost a najma reproduksottelnosť presnootti zhotovovaných puzdier.The production methods of the sleeve bushings, mainly the calculation of the preforming of the precursor stock are based on very accurate calculations. As has been confirmed experimentally, even this method does not guarantee the often desired accuracy and, in particular, the reproducibility of precision housings.

Uvedené nedostatky odstraňuje zar^de^e na odstraňovante rovných úsekov u tenkostenných ložisksvУch pázdíer, ktorého podstata spočívá v tom, že pozostáva zo strižnice tvaru obráteného písmena T, na ktorej je položená na dve polovice pozdížne delená upínacia část prstence ukotveného spolu so ttiiinicsu prostredníctoom úpiniek k základovej doske. Na tejto je rozoberatelne uchytená kolmo usporiadaná příruba, ku ktorej je upevněný mmtor s priam^o^i.aro vratné sa pohybujúcié piestom s pirttnicsu opatřenou pri^nikom, spojeným cez ti^hla, umiestnené súmerne po oboch stranách zar^dmi^ so stláčacím puzdrom. Na tomto puzdre je nasunuté pozdížne rozřezané elastické puzdro, opreté jedným čelom o osadenie stláča^eho puzdra a druhým čelom o opěrné puzdro, poloha ktorého je vzhladom k přírubě vymedzená rozperami a vzhladom k prstenců podložkami. V otvore prstence je pozdížne usporiadaný nosník so ttrižnSkoé, ktorý je vedený vo vodiacej doske, rozoberatelne uchytenej k strižnici, pričom na nosník je položená konzola, uchytená na ěmkadle lisu. K podstatě paltrí aj to, že jedna polovica upínacej časti prstenca je k strižnici prichytená pomocou skrutiek a druhá polovica upínacej časti prstenca je posuvné uložená na strižnici, pričom obe polovice sú spojené cez zv^slú část strižnice prostredníctooé regulačných sSrutieS. V otvoroch pre regulačně skrutky sú uložené vyměntelné puzdra. Posuvná polovica upínacej časti prstenca je na koncoch opatřená držiekom pre rozoberatelné uchytenie úchylkomera tak, aby jeho hrot bol v dotyku s pevnou polovicou upínacej časti prstenca. Medzi vodiacu došku a nosník strižníka sú ulsiené pružiny, pr^om nosník je opatřený aspoň jedným otvorom s vymedzovacou storrtkou zaskrutkovanou do vodiacej došky pre posuvné spojenie nosníka s vodiacou doskou. Elastické puzdro je vyrobené z uretánu, alebo je tvořené pneummatckou, alebo hydraulickou poduškou. Slrižník má prierez v tvare obdížnika, alebo v tvare písmena I.The above-mentioned drawbacks are eliminated by means of the removal of straight sections of thin-walled claws, which consists in the fact that it consists of an inverted T-shaped punch on which the longitudinally divided clamping part of the ring anchored together with ttiiinicsu is inserted through tines to the base plate. On this is detachably mounted a perpendicularly arranged flange to which is attached a mmtor with a reciprocating reciprocating piston with a piercing pin, connected symmetrically, located symmetrically on both sides of the compression device. case. A longitudinally cut elastic sleeve is supported on this sleeve, supported by one face against the shoulder of the compression sleeve and the other face against the supporting sleeve, the position of which is defined relative to the flange by spacers and relative to the rings by washers. In the opening of the ring there is a longitudinally arranged traction beam which is guided in a guide plate detachably fastened to the punch, while a bracket is placed on the beam, which is fastened to the press ram. In essence, one half of the ring clamping part is fastened to the die by means of screws and the other half of the ring clamping part is slidably mounted on the die, the two halves being connected through the remaining part of the die by means of the regulating twists. Replaceable bushings are housed in the holes for the control screws. The sliding half of the clamping portion of the ring is provided at the ends with a handle for detachably attaching the dial indicator so that its tip contacts the fixed half of the clamping portion of the ring. The guide plate and the support and the editing tp u u l p i p e Ružin y, cl ^ om tp carrier is provided with just a single hole in the spacer storrtkou screwed to a guide plate for sliding connection with the carriage guide plate. The elastic casing is made of urethane, or is formed by a pneumatic or hydraulic cushion. The rectangle has a cross section in the shape of a rectangle or in the shape of the letter I.
