Description
Vynález sa týká sústružníckeho noža a rieši geometriu řezného klina tvarovača triesky.The invention relates to a turning knife and solves the geometry of the cutting wedge of the chip former.
Doposial známe jednožliabkové tvarovače vytvořené na vyměnitelných režných doštičkách majú fázky skloněné pod kladným uhlom a pracujú v nie příliš širokých oblastiach posuvov a híbok pri roznych druhoch obrábaných materiálov. Je to sposobené tým, že doštičky boli vyrobené na základe experimentálnych skúseností výrobcov a v geometrických parametroch sa vždy medzi sebou líšia.Previously known single-groove formers formed on exchangeable cutting inserts have phases inclined at a positive angle and operate in not too wide feed and depth regions for various types of machined materials. This is due to the fact that the inserts were made based on the experimental experience of the manufacturers and always differ in geometric parameters.
Uvedené nedostatky odstraňuje režná doštička s jednožliabkovým tvarovačom triesky, ktorej podstata spočívá v tom, že žliabok má šířku v rozmedzí 1,56 až 1,64 mm a je ukončený fázkou, o šírke 0,08 až 0,12 mm, skloněnou pod záporným uhlom v intervale 27 ° až 31 °, uhol medzi druhou plochou čela a rovnou rovnoběžnou s upínacou rovinou je v rozmedzí 18° až 20 °, uhol medzi výstupnou rovinou tvarovača a upínacou rovinou je 14 0 až 16 °, výška schodíka je 0,07 až 0,11 mm, poloměr žliabku je v rozmedzí 1,45 až 1,49 mm a poloměr hrotu je 0,8 mm.The aforementioned drawbacks are remedied by a one-groove-type gray chipboard having the width of the groove in the range of 1.56 to 1.64 mm and terminating in a 0.08 to 0.12 mm wide phase inclined at a negative angle in the range 27 ° to 31 °, the angle between the second face and a flat face parallel to the clamping plane is between 18 ° and 20 °, the angle between the exit plane of the former and the clamping plane is 14 0 to 16 °, the height of the step is 0.07 to 0.11 mm, the groove radius is between 1.45 to 1.49 mm and the tip radius is 0.8 mm.
Doštičkou s tvarovačom podlá vynálezu sa dosahuje rozšírenie oblasti jeho použitia, čím je možné lepšie využívat schopnosti obrábacích strojov a automatov pri sústružení, kde jedným z problémov je aj druh a velkost odoberanej triesky. Doštičkou sa zabezpečuje vhodná trieska, čím sa zvyšuje bezpečnost pri práci a ulahčuje sa obsluha stroja.The insert with the former has the widening of its field of application, making it possible to make better use of the capabilities of machine tools and automatic turning machines, where one of the problems is the type and size of the chip to be removed. A suitable chip is provided by the insert, increasing safety at work and facilitating machine operation.
Příklad geometrie tvarovača je znázorněný na pripojenom výkrese, kde na obr. 1 je čelný pohfad na uzavretý tvar fázky, na obr. 2 otvorený tvar fázky zhotovený na štvorcových doštičkách a na obr. 3 je znázorněný rez rovinou A - A.An example of the geometry of the former is shown in the accompanying drawing. 1 is a front view of the closed phase shape; FIG. 2 shows an open phase shape made on square plates and FIG. 3 is a section along the line A - A.
Vyměnitelná režná doštička je opatřená jednožliabkovým tvarovačom vytvořeným buď vylisováním, alebo vyiskrením. Boli odskúšané doštičky s nasledovnými parametrami tvaru žliabku tvarovača: šířka w žliabku v rozmedzí 1,56 až 1,64 mm, šířka f fázky 0,08 až 0,12 mm, uhol sklonu fázky — 27 0 až — 31 °, uhol η medzi druhou plochou čela a rovinou rovnoběžnou s upínacou rovinou v rozmedzí 18 0 až 20 °, uhol η medzi výstupnou rovinou tvarovača a upínacou rovinou 14 ° až 160 výška h’ schodíka 0,07 až 0,11 mm, poloměr R žliabku v intervale 1,45 až 1,49 mm a poloměr r hrotu 0,8 mm.The removable cutting plate is provided with a one-groove former formed by either pressing or stamping. Plates with the following groove groove shape parameters were tested: groove width w in the range of 1.56 to 1.64 mm, phase f width 0.08 to 0.12 mm, phase angle - 27 0 to - 31 °, angle η between the second face of the face and the plane parallel to the clamping plane in the range of 18 0 to 20 °, the angle η between the outlet plane of the former and the clamping plane 14 ° to 16 0 height h 'of the step 0.07 to 0.11 mm, groove radius R at 1 45 to 1.49 mm and a tip radius r of 0.8 mm.
Tvarovače s danými parametrami tvarovali triesku o dlžkach triesky od 0,5 až 6 cm pri posuvoch od 0,10 do 0,56 mm/ot hrůbkách triesok od 1 do 5 mm, pri režných rýchlostiach od 120 do 150 m/min. a pri roznych druhoch obrábaných materiálov čo predstavuje v porovnaní s doteraz používanými tvarovacími rozšírenie oblasti o 4 až 40 °/o.The formers with the given parameters formed a chip with chip lengths of 0.5 to 6 cm at feeds of 0.10 to 0.56 mm / rev chip depths of 1 to 5 mm, at an average speed of 120 to 150 m / min. and in the case of various types of machined materials, which represents an area extension of 4 to 40 [deg.] / [deg.] relative to the previously used shaping materials.
Význam tvarovača, ktorý je predmetom ochrany je aj v tom, že ho možno vyrobit nielen na štvorcové doštičky, ale aj na trojúhelníkové a kosoštvorcové doštičky.The importance of the crimper which is the subject of protection is also that it can be produced not only for square inserts, but also for triangular and rhombic inserts.
