Description
Oblasť technikyTechnical field
Vynález sa týka spôsobu výroby jednodielneho kolesa z ľahkého kovu, najmä z vytvrditeľnej tvarovacej zliatiny hliníka, a to plynulým pretlačovaním alebo valcovaním z polotovaru. Plynulé pretlačovanie alebo valcovanie na zhotovenie konečného výrobku je realizované v horúcom stave, pri homogenizačnom žíhaní pri teplotách od približne 530 °C, v závislosti od druhu zliatiny, s nasledujúcim rýchlym ochladením a tepelným vytvrdením pri teplotách od 150 °C do 200 °C. Na zhotovenie jednodielneho kolesa z ľahkého kovu sú vhodné najmä zliatiny typu AlMgSi.The invention relates to a method for producing a one-piece light-alloy wheel, in particular a hardenable aluminum forming alloy, by continuously extruding or rolling from a blank. Continuous extrusion or rolling to produce the final product is carried out in the hot state, by homogenizing annealing at temperatures from about 530 ° C, depending on the alloy, followed by rapid cooling and thermal curing at temperatures from 150 ° C to 200 ° C. AlMgSi-type alloys are particularly suitable for the production of a one-piece light metal wheel.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Pri známych spôsoboch vytvorenia jednodielnych kolies tohto druhu sú ako polotovary používané takzvané prírubové polotovary, pri ktoiých je príruba v prierezu približne pravouhlo radiálne rozštiepená a na to je vyvalcované lôžko rafika. Ako polotovary sú rovnako používané miskovité polotovary, pri ktorých je z príslušnej tvarovanej okrajovej časti rovnako vyvalcované lôžko ráfika s pomocou podpery.In known methods of making one-piece wheels of this kind, so-called flanged blanks are used as blanks, in which the flange is approximately radially split radially in cross-section and a refined bed is rolled for this purpose. Also used as blanks are cup-shaped blanks in which the rim bed is also rolled out of the respective shaped rim portion by means of a support.
Pred rozštiepením a konečným valcovaním prírubového polotovaru alebo konečným valcovaním miskovitého polotovaru sú v jednej pracovnej operácii pri známych spôsoboch polotovary ohriate na teplotu v rozmedzí od 150 °C do 250 °C. Po dohotovení nasleduje homogenizačné žíhanie pri teplotách približne 530 °C v závislosti od druhu zliatiny a ďalej tepelné vytvrdzovanie pri teplotách od 150 °C do 200 °C.Prior to cleavage and final rolling of the flanged blank or final rolling of the cup-shaped blank, in one operation, the blank is heated to a temperature in the range of 150 ° C to 250 ° C in known processes. The finish is followed by homogenizing annealing at temperatures of approximately 530 ° C depending on the alloy and thermal curing at temperatures from 150 ° C to 200 ° C.
Pri homogenizačnom žíhaní a rýchlom ochladení valcového polotovaru vzniká nebezpečie zborenia, najmä lôžka ráfika. Okrem toho ohrev nutný na spracovanie valcovaním dodatočne zvyšuje energetické náklady.The homogenisation annealing and rapid cooling of the cylindrical blank creates the risk of collapse, especially of the rim bed. In addition, the heating required for rolling processing additionally increases the energy costs.
Podstata vynálezuSUMMARY OF THE INVENTION
Úlohou vynálezu je celkom zabrániť zboreniu vyvalcovaných častí a znížiť pritom energetické náklady pri spôsobe v úvode zmieneného druhu.The object of the invention is to prevent the rolled parts from collapsing whilst at the same time reducing the energy costs of the process of the kind mentioned at the outset.
Táto úloha je podľa vynálezu riešená pomocou zmieneného spôsobu, ktorý sa vyznačuje tým, že po homogenizačnom žíhaní polotovaru je v závislosti od druhu zliatiny realizované kontrolované rýchle ochladenie na teplotu približne 200 °C, Pri tejto teplote tak, aby nebol polotovar ohriaty na vyššiu teplotu, je plynulým pretlačovaním alebo valcovaním zhotovený konečný výrobok, ktorý je potom tepelne vytvrdzovaný.This object is achieved according to the invention by the above-mentioned method, characterized in that, after homogenization annealing of the workpiece, a controlled rapid cooling to about 200 ° C is carried out, depending on the type of alloy, at this temperature so that the workpiece is not heated to a higher temperature. the finished product is produced by continuous extrusion or rolling and is then thermally cured.
Prfklad uskutočnenia vynálezuEXAMPLE OF THE INVENTION
Kontrolované rýchle ochladenie nevyvalcovaného polotovaru z procesu homogenizačného žíhania a to na teplotu približne 200 °C v závislosti od druhu zliatiny a nasledovné konečné valcovanie, celkom zabraňuje zboreniu valcovaním dohotoveného dielu, ktoré by mohlo byť spôsobené prudkým ochladením a nasledovným opracovaním na sústruhu. V dôsledku kontrolovaného rýchleho ochladenia polotovaru v závislosti od druhu zliatiny na teplotu približne 200 °C, prípadne opätovným ohrevom na túto teplotnú hladinu, je na rozdiel od známych spôsobov, pri ktorých je opätovný ohrev realizovaný z teploty okolia, dosiahnuté pri tomto spôsobe veľkej úspory energie. Pri tejto teplotnej úrovni, ktorá v závislosti od druhu zliatiny dosahuje asi 200 °C, je realizované rozštiepenie polotovaru a následné plynulé pretlačovanie alebo valcovanie miskovitého polotovaru s cieľom dohotoviť výrobok. Vyvalcovanie polotovaru po kontrolovanom rýchlom ochladení z teploty homogenizačného žíhania tu vedie k zlepšeniu tvorby štruktúry materiálu a tým tiež k zlepšeniu jeho úžitkových vlastnosti. Známym spôsobom potom nasleduje tepelné vytvrdzovanie.The controlled rapid cooling of the non-rolled blank from the homogenization annealing process to a temperature of approximately 200 ° C depending on the alloy and subsequent final rolling completely prevents collapse of the finished workpiece which could be caused by rapid cooling and subsequent machining on the lathe. Due to the controlled rapid cooling of the workpiece, depending on the type of alloy, to a temperature of approximately 200 ° C, or to reheating to this temperature level, in contrast to known methods in which reheating is carried out from ambient temperature, . At this temperature level, which, depending on the type of alloy, reaches about 200 ° C, the workpiece is split and then continuously extruded or rolled the cup-shaped workpiece to complete the product. Rolling of the workpiece after controlled rapid cooling from the homogenizing annealing temperature here leads to an improvement in the formation of the structure of the material and thus to an improvement in its performance. Thermal curing then follows in a known manner.
Do rámca vynálezu spadá rovnako riešenie, podľa ktorého je rýchle ochladenie po homogenizačnom žíhaní realizované vyššou rýchlosťou ochladzovania prostredníctvom vodnej sprchy so stanoveným množstvom vody a teplotou vody. Tým je možné dosiahnuť dobrých mechanických vlastností materiálu. Možné je rovnako aj také vyhotovenie, podľa ktorého je vodnou sprchou rýchlo ochladzovaných viac polotovarov, uložených vo vhodných stojanoch.Also within the scope of the invention is a solution according to which rapid cooling after homogenization annealing is realized by a higher cooling rate by means of a water spray with a specified amount of water and water temperature. Thus, good mechanical properties of the material can be achieved. It is also possible to design a plurality of workpieces stored in suitable racks quickly cooled by a water spray.
Tento spôsob nachádza výhodné využitie pri zhotovení jednodielneho kolesa z ľahkého kovu, najmä zo zliatiny druhu AlMgSi.This method finds advantageous use in the manufacture of a one-piece light metal wheel, in particular of an AlMgSi-type alloy.
Ďalšiu výhodu je možné vidieť v tom, že teplota valcovania, ktorá je v závislosti od druhu zliatiny približne 200 °C, a ktorá musí byť zachovaná v celom procese pretlačovania alebo valcovania, môže byť využitá pri následnom tepelnom vytvrdzovaní.A further advantage can be seen in the fact that the rolling temperature, which, depending on the type of alloy, is approximately 200 ° C, and which must be maintained throughout the extrusion or rolling process, can be used in subsequent thermal curing.
V dôsledku minimálnej deformácie na čisto vyvalcovanom polotovare, môžu byť podstatne zmenšené prídavky na opracovanie lôžka ráfika. Tým sú rovnako zmenšené odchýlky obvodového hádzania a nevyváženosť.Due to the minimal deformation on the pure rolled blank, the rim bed allowances can be considerably reduced. This also reduces the runout deviations and imbalance.
