Abstract
Účelom vynálezu Je podstatné zeféktívnenie výroby brúsnych kotúčov na opracovanie profilov a líšt z dřeva a umělých hmĎt. Uvedeného účelu sa dosiahne tým, že profilovaná lišta s vopred vyhotovenými priečnymi zubami sa posúva oproti otáčajúcemu sa brúsnemu kotúču tvaru valca a zarezáva sa do něho.Purpose of the Invention It is essential to make the invention more effective production of abrasive wheels for machining profiles and moldings made of wood and man-made plastics. This purpose is achieved by being profiled bar with pre-made transverse the teeth moves against the rotating to the cylindrical grinding wheel and cuts into it.
Description
Vynález sa týká spůsobu výroby obvodového profilu brusného kotúča na brúsenie profilov a tvarových líšt z dřeva a umělých hmot.The invention relates to a method for producing a peripheral profile of a grinding wheel for grinding profiles and moldings of wood and plastics.
Doposial sa profily tvarových brúsnych kotúčov vyrábali priamo vo formě pri výrobě brúsneho kotúča alebo sústružením do válcového polotovaru. Prvý popísaný spůsob má nevýhodu v tom, že pre rožne tvary je potřebné vyrábať vždy nové formy, ktoré sú velmi nákladné.So far, the profile grinding wheel profiles have been produced directly in the mold during the production of the grinding wheel or by turning into a cylindrical blank. The first method described has the disadvantage that it is necessary for the various shapes to produce new molds which are very expensive.
V druhom případe sa do válcového polotovaru sústruží požadovaný tvar, profil tvarovým nožom alebo podlá šablóny. Pri tomto spůsobe v důsledku výrobných nepřesností a zložitosti profilu nie je možné zaistit požadovanú přesnost.In the latter case, the desired shape, profile with a profile knife or a template is turned into a cylindrical blank. In this way, due to manufacturing inaccuracies and complexity of the profile, the required accuracy cannot be ensured.
V oboch prípadoch sa pri výrobě prejavuje malá produktivita práce spůsobená značnou prácnosťou.In both cases, low labor productivity due to labor intensive production is manifested in production.
Uvedené nedostatky známých spůsobov do značnej miery odstraňuje spůsob výroby obvodového profilu brúsneho kotúča podlá vynálezu, ktorého podstatou je to, že profilovaná lišta s vopred vyhotovenými priečnymi zubami sa posúva oproti otáčajúcemu sa brúsnemu kotúču tvaru valca a zarezáva sa do něho.The aforementioned drawbacks of the known methods are largely eliminated by the method of manufacturing the circumferential profile of the grinding wheel according to the invention, which is characterized in that the profiled bar with pre-formed transverse teeth is displaced and cut into the rotating grinding wheel.
Výhody vynálezu spočívajú hlevne v tom, že na výrobu obvodovej profilovanej funkčnej plochy brúsneho kotúča nie je potřebný další špeciálny nástroj a tvarovaná lišta s priečnymi zárezmi zároveň vykonává funkciu obrábacieho nástroja, čo je zároveň novým účinkom vynálezu. Využitím spůsobu podlá vynálezu sa zvýši produktivita práce, znížia sa náklady a ušetria sa pracovně sily na ručné dobrusovanie dielcov.The advantages of the invention lie in the fact that no special tool is required for the production of the circumferential profiled functional surface of the grinding wheel, and the shaped cross-section bar simultaneously performs the function of a cutting tool, which is also a new effect of the invention. By using the method according to the invention, labor productivity is increased, costs are reduced and labor for manual grinding of parts is saved.
Spůsobom výroby obvodového profilu do válcového polotovaru brúsneho kotúča s vazbou z polyuretanu a brusivá sa dá dosiahnuť to, že požadovaný profil je možné do polotovaru brúsneho kotúča vytvořit priamo obrábaným dielcom, lištou a pod. Polotovar brúsneho kotúča, vyhotovený vstreknutím do formy, sa otáča okolo svojej osi a súčasne protibežne k zmyslu otáčania brúsného kotúča sa prisúva profilová lišta vopred opatřená priečnymi zubami, ktoré sú tvořené priečnymi zárezmi, napr. pilovým kotúčom.By producing a circumferential profile into a cylindrical grinding wheel blank with a polyurethane-abrasive bond, it is possible to achieve the desired profile in the grinding wheel blank by directly machined workpiece, bar or the like. The grinding wheel blank produced by injection molding is rotated about its axis, and at the same time, opposite to the direction of rotation of the grinding wheel, a profile bar provided with transverse teeth, which are formed by transverse notches, e.g. saw blade.
S výhodou je možné použit pre vytvorenie profilu profilovú lištu z tvrdšieho dřeva ako sú tvarové lišty, ktoré sa budú obrábať. Prisúvaním brúsneho kotúča k profilovej lište s priečnymi zubami, ktoré majú v důsledku priečnych kolmých zárezov nulový uhol čela a chrbta, dochádza na hrané zubov najprv k plastickej deformácii materiálu brúsneho kotúča, neskor k jeho odoberaniu a obrábaniu, nákolko drážky medzi zubami umožňujú odvádzanie odoberaného materiálu kotúča.Preferably, a profile rail of harder wood than the moldings to be machined can be used to form the profile. By sliding the grinding wheel to the profile bar with transverse teeth, which have a zero face and back angle due to the transverse perpendicular notches, the grinding wheel material is first plasticly deformed on the toothed edges, later it is removed and machined. roll.
Niekolkonásobným opakováním přísuvu brúsneho kotúča k profilovej lište s priečnymi zubami sa do polotovaru brúsneho kotúča vytvoří požadovaný profil. Takto vyhotovený profil brúsneho kotúča sa dokonale zhoduje s profilom opracovávanej tvarovej lišty, ktorá je súčasne aj pracovným obráběcím nástrojom.By repeatedly repeating the infeed of the grinding wheel to the profile bar with transverse teeth, the desired profile is created in the grinding wheel blank. The profile of the grinding wheel made in this way perfectly matches the profile of the machined molding, which is also a working tool.
Výhodné využitie vynálezu je možné na dokončovacie brúsenie a brúsenie povrchových úprav různých profilových dielcov, okrasných líšt, obrazov, okien i na brúsenie rotačných dielcov, napr. nůh stoličiek a pod.Advantageous application of the invention is possible for finishing grinding and surface grinding of various profile parts, ornamental moldings, pictures, windows and for grinding of rotary parts, e.g. foot chair and the like.
