Abstract
Nožová hlava rieši problém mechanického čistenia zváracích hubíc pomocou výkyvných nožíkov. Nožová hlava pozostáva z telesa, v ktorom sú upevněné výkyvné .nožíky, výkyvné uložené na čapoch a zaistené skruitkou, pričom teleso je opatřené zaisťovacím čapom pre upevnenie na pohonnej jednotkeThe knife head solves the problem of mechanical cleaning of welding nozzles using swinging knives. The knife head consists of a body in which swinging knives are mounted, swinging knives mounted on pins and secured with a screw, while the body is provided with a locking pin for fastening to the drive unit.
Description
Vynález sa týká nožovej hlavy pre mechanické čistenie zváracích hubíc.The invention relates to a cutter head for mechanical cleaning of welding nozzles.
Doteraz známe prevedenia mechanického čistenia zváracích hubíc sú zabezpečené pomocou pružin, ocelových kefiek, alebo pevnej nožovej hlavy. Pružiny a ocelové kefky sa do určitej miery prispůsobujú tvaru zváracích hubíc, ako aj nepresnostiam pri ich polohovaní voči nástrojů čistenia. Pri vSčšom znečistění zváracích hubic od rozstrekovaného kovu, ku ktorému pri zváraní dochádza, nie sú schopné pružiny ani ocelové kefky tieto vyčistit, dokonca dochádza k mechanickému poškodeniu pružin ako aj ocelových kefiek. Pevná nožová hlava je schopná vyčistit aj velmi znečistěné zváracie hubice, avšak neprisposobí sa tvaru zvúracej hubice a ani prípadnej nepřesnosti polohovanía zváracej hubice voči nožovej hlavě.The hitherto known embodiments of mechanical cleaning of the welding nozzles are provided by springs, steel brushes or a fixed cutter head. Springs and steel brushes to some extent conform to the shape of the welding nozzles as well as the inaccuracies in their positioning relative to the cleaning tools. When the welding nozzles are more contaminated by the welding metal, the springs and steel brushes are not able to clean them, even causing mechanical damage to the springs and steel brushes. The fixed cutter head is also capable of cleaning very dirty welding nozzles, but does not fit the shape of the rotary nozzle or any inaccuracy in positioning the welding nozzle relative to the cutter head.
Uvedené nedostatky pružin, ocelových kefiek a pevných nožových hláv sa dajú odstrániť podlá vynálezu, ktorého podstata spočívá v tom, že pozostáva z telesa nožovej hlavy, v ktorom sú upevněné výkyvné nožíky, výkyvné uchytené na čapoch a zaistené skrutkou. Teleso nožovej hlavy je opatrené zaisťovacím čapom pre upevnenie na pohonnej jednotke.The aforementioned drawbacks of springs, steel brushes and fixed cutter heads can be removed according to the invention, which consists in the fact that it consists of a cutter head body in which swinging knives are fixed, pivotally mounted on the pins and secured by a screw. The cutter head body is provided with a locking pin for attachment to the drive unit.
Hlavné výhody nožovej hlavy pre mechanické čistenie zváracích hubíc pomocou výkyvných nožíkow spočívajú v tom, že tieto výkyvné nožíky sa prispůsobujú tvaru zvá- 6 7 4 racích hubíc a do určitej miery sú schopné korigovat nepřesnosti polohovanía zváracích hubic, voči nástrojů čistenia, teda voči samotným nožíkom, sú dostatočné pevné, aby vyčistili aj velmi znečistěné zváracie hubice.The main advantages of the cutter head for the mechanical cleaning of the welding nozzles with the help of swivel cutters are that the swiveling blades conform to the shape of the claw nozzles and to some extent are able to correct the inaccuracies in the positioning of the welding nozzles against the cleaning tools, i.e. the blades themselves are strong enough to clean even very dirty welding nozzles.
Na výkrese je nožová hlava pre mechanické Čistenie zváracích hubíc pomocou výkyvných nožlkov nakreslené v řeze.In the drawing, the cutter head for mechanical cleaning of the welding nozzles is drawn in section by means of swiveling legs.
Nožová hlava pre mechanické čistenie tvořené nožíkmi 1 uloženými v telese 2 nožovej hlavy a výkyvnými okolo čapov 3, zaistenými skrutkou 4. Nožová hlava je připojená na hnací člen 6 a začapovaná zaisťovacím čapom 5.Knife head for mechanical cleaning consisting of knives 1 housed in knife head body 2 and pivoted about pins 3 secured by screw 4. The knife head is connected to drive member 6 and tapped by locking pin 5.
Funkcia nožovej hlavy pre mechanické čistenie zváracích hubíc je nasledovná:The cutter head function for mechanical cleaning of the welding nozzles is as follows:
Po roztočení nožovej hlavy výkyvné nožíky 1 prilahnú na vnútornú stranu kužela v telese 2 nožovej hlavy, zváracia hubice 7 sa nasunie po ich skosení na ne, pretože jej vstupný priemer je menší ako je celkové roztvorenie nožlkov 1 přitlačí ich k osi rotácie, po zasunutí do zváracej hubice 7 sa výkyvné nožíky 1 roztvoria a prilahnú na vnútornú stenu zváracej hubice 7, tým dochádza k jej dokonalému vyčisteniu.Upon rotation of the cutter head, the swiveling blades 1 adhere to the inner side of the cone in the cutter head body 2, the welding nozzle 7 is slid upon them because its inlet diameter is less than the total opening of the legs 1 presses them to the axis of rotation upon insertion into With the welding nozzle 7, the swiveling knives 1 open and adhere to the inner wall of the welding nozzle 7, thereby completely cleaning it.
Konštrukcia nožovej hlavy pre mechanické čistenie zváracích hubíc výkyvnými nožíkmi podlá tohoto vynálezu umožňuje značné predlžiť životnost zváracích hubíc a zefektivnit proces zvárania.The design of the cutter head for mechanical cleaning of the welding nozzles by the swiveling scissors according to the invention makes it possible to considerably extend the life of the welding nozzles and to make the welding process more efficient.
