Abstract
Riešenie je určené pre obojsmerové hoblovanie rovinných plóch. K tomu je použitý nóž s dvoma symetrickými režnými časťami, zakončenými režnými klinmi, ktorého držiak je výkyvné uložený v suporte stroja.The solution is for both directions planing flat planes. It is used knife with two symmetrical gray parts, ending with gray wedges, whose bracket is pivotally mounted in a support machine.
Description
Vynález sa týká noža na oboj směrové hoblovanie rovinných plóch.The invention relates to a knife for both directional planing of planar surfaces.
V súčasnosti sa hoblovanie rovinných plóch prevádza len jednosměrovým hoblováním, a to tak, že nóž pri hoblovaní je v pracovnej polohe len v jednom smere pohybu štola, po skončení posuvu štola hoblovačky (šmýkadla u obrážečky) sa nóž odklopí z pracovnej polohy, spatný pohyb štola (šmýkadla u obrážačky) je nevyužitý, a takto dochádza k časovým stratám, ako aj k nižšiemu využitiu energie. Všetky známe hoblovacie nože v súčasnosti majú len jeden režný kliň, odklápanie noža pri spatnom pohybe štola je nevyhnutné, aby nedošlo k odlomeniu režného klinu. V snahe využit spatný pohyb štola ako pracovný, sa robili rózne pokusy, ktoré sa vo výrobě neosvědčili, boli nepraktické a v konečných dósledkoch ani ekonomicky výhodné. Například: nóž bol vyrobený tak, že mal aj pre spStný pohyb režný kliň, uchytený bol pevne, čiže nebol odklopný a tak došlo po niekolkých pohyboch štola k vylomeniu toho režného klina, ktorý nebol v pracovnej polohe, ale chrbtom klina třel o obrobená plochu. Další pokus o využitie spatného pohybu spočíval v tem, že boli použité dva nožové držiaky, nasměrované pre obidva směry, do ktorých boli upnuté běžné hoblovacie nože. Každý nóž bol však nastavený na obrábanie dvoch róznych obrobkov, upnutých na stole hoblovačky. Takýto spósob je v praxi použitelný, avšak pre zdíhavé nastavovanie sa tiež nepoužívá. Preto sa na zvýšenie produktivity práce skór využívá kaskádovité, viacnožové hoblovanie, pri ktorom sú nože upnuté za sebou s odstupňovaným záberom, avšak toto je len jednosmerové, a tiež pre zložitosť nastavovania velmi málo používané.At present, planing of planar surfaces is performed only by unidirectional planing, so that the blade is in the working position in only one direction of the adit during planing, after the end of the movement of the planer adit (slide at the slotting machine) (slider at the slotting machine) is unused, and this results in time loss as well as lower energy use. All known planing knives currently have only one cutting wedge, tilting the knife in the wrong movement of the shaft is necessary to avoid breaking off the cutting wedge. In an attempt to use the wrong movement of the adit as a work, various experiments were carried out, which were not successful in production, were impractical and, ultimately, not economically advantageous. For example: the knife was made so that it had a cutting wedge for the forward movement, it was fastened firmly so that it was not hinged, and after several movements of the tunnel, the cutting wedge which was not in working position but rubbed against the machined surface. Another attempt to use the wrong movement was to use two knife holders directed in both directions in which conventional planing knives were clamped. However, each knife was set to machine two different workpieces clamped on a planer table. Such a method is applicable in practice, but is also not used for a hasty adjustment. Therefore, cascading, multi-blade planing is used to increase scoring productivity, in which the blades are clamped one behind the other with staggered engagement, but this is only unidirectional and also very little used for the adjustment complexity.
Uvedené nedostatky rieši konštrukcie hoblovacieho noža podlá vynálezu. Podstata vynálezu noža spočívá v tom, že nóž je tvořený telesom, ktoré je na jednom konci upravené na upnutie, ktoré móže byt podobné ako u fréz, a na druhom konci z telesa noža vyčnievajú dve vidlicovité, symetrické, režné časti.These drawbacks are solved by the planer blade construction according to the invention. According to the invention, the knife consists of a body which is adapted at one end to be clamped, which may be similar to a milling cutter, and at the other end two forked, symmetrical, cutting parts protrude from the knife body.
Predmet vynálezu je zobrazený na priloženom výkrese, kde obr. 1 znázorňuje nóž pri hoblovaní v jednom smere a obr. 2 v spatnom smere.The object of the invention is illustrated in the accompanying drawing, wherein FIG. 1 shows a blade when planing in one direction, and FIG. 2 in the wrong direction.
Nóž je tvořený telesom (1) noža, ktoré je prispósobené na jednom konci pre upnutie, ktoré móže byt podobné ako u fréz, a na druhom konci z něho vidlicovité vyčnievajú dve symetrické režné časti (4a, 4b), ktoré sú zakončené režnými klinmi (s uhlom beta). Vidlicovité vyčnievanie odporúčame preto, aby odvod tepla bol čo najlepší a hmotnost noža, aby bola menšia ako pri plnom zakončeni. Nóž je upevněný v držiaku (2), ktorý je otočným čapom (5) a mechanizmom naklápania spojený so suportom hoblovačky.The knife consists of a knife body (1) which is adapted at one end for a clamping, which may be similar to a milling cutter, and at the other end a forked protruding two symmetrical cutting parts (4a, 4b) terminated by cutting wedges (4). with beta angle). The fork protrusion is recommended for the best heat dissipation and the weight of the blade to be less than at the full end. The blade is mounted in a holder (2) which is connected to the shank support by a pivot pin (5) and a tilting mechanism.
Po upnuti obrobku (6) na stól hoblovačky, a po upnutí noža do držiaka (2) naklonenom o uhol fí tak, (obr. 1) aby režná časť (4a) noža, pre režný pohyb v smere A bola připravená pre uniknutie do obrobku (6,, následuje nastavenie noža, ako pri doterajších hoblovačkách.After clamping the workpiece (6) on the planer table, and after clamping the knife in the holder (2) inclined at an angle phi (Fig. 1), the cutting portion (4a) of the knife is ready for escape into the workpiece (6, followed by blade adjustment, as in previous planing machines.
Po dokončeni nastavenia noža uvedieme do činnosti stól hoblovačky, a takto sa začne obrábanie obrobku (6), ktorý je upnutý na stole hoblovačky. Na konci posuvu štola preklápací mechanizmus překlopí nóž s držiakom (2) okolo čapu (5) a uhol 2 fí (obr. 2) a takto je nóž připravený na využitie spatného pohybu štola (Β), aby aj tento pohyb bol pracovný. Pri tomto pohybe je v zábere druhá režná časť (4b) noža. Opatovné nastavenie noža nie je potřebné, lebo nóž je symetrický.When the blade adjustment is complete, the planer table is activated and the workpiece (6) is clamped on the planer table. At the end of the drift of the tunnel, the tilting mechanism tilts the blade with the holder (2) around the pin (5) and the angle of 2 phi (Fig. 2) and is thus ready to use the wrong drift of the tunnel (Β). During this movement, the second cutting portion (4b) of the knife is engaged. Careful adjustment of the blade is not necessary as the blade is symmetrical.
