Vynález sa týká zariadenia na zhotovova-nie čelných zvarových ploch na rúrachz plastov.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for making front weld surfaces on a plastic pipe.
Doteraz sa zvarové plochy na rúrachz plastov zhotovovali mimo zváracieho strojana sústruhoch alebo frézách. To znamená,že musí byť k dispozícii sústruh alebo fréza,čím sa zvyšuj ú náklady na vyhotovovaniezvarových ploch. Okrem toho montáž rúr doobjímok zváracieho stroja nezaručuje para-lelnosť zvarových ploch rúr. Ďalej sa na zho-tovovanie zvarových ploch na rúrach z plas-tov upnutých na zváracom stroji používásústavia nožov umiestnených 'na dvoch para-lelných kotúčoch. Týmto zariadením sa zva-rové plochy zhotovujú ručně a přerušovanýrotačný pohyb sa deje pomocou mechanizmupozostávajúceho z rohatky a západky. Ne-výhodou je pomalé zhotovovanie zvarovýchploch a nemožnosť vyhotovit zvarové plochypre šikmé zvary rúr. Na vyhotovenie čelnýchzvarových ploch na rúrach z plastov upnu-tých na zváracom stroji sa tiež používajúparalelné kruhové pily, ktoré ak sa zasúvalido čiel rúr, postupné vyhotovili obe zvarovéplochy. Nevýhodou je, že třeba použit rotač-ně pily minimálně s dvojnásobným prieme-rom voči priemeru rúr a okrem toho v prie-behu opracovávania rúr sa rotačně pily roz-biehali, hlavně pri ich prehriatí. Zvarovéplochy na rúrach z plastov a to na obochrúrach súčasne, sa zhotovujú aj pomocourotujúcich fréz umiestnených na suporte tak,že rotujúce frézy vytvárajú paralelné plochy.Nevýhodou však je že zvarová plocha zho-tovená súbežným frézováním je hladká azvarová plocha zhotovená protibežným fré-zováním je drsná a pre zváranie nevhodná.Zhotovovanie zvarových ploch na rúrachz plastov na zváracom stroji, alebo mimoněho pomocou laserového lúča dává sicedobré výsledky, ale s ohladom na drahé za-riadenie a zvýšené bezpečnostně požiadavkyz dovedu použiiitia laserového lúča je to preběžné použitie neekonomické.Until now, weld surfaces for the plastic pipe have been made outside of the welding machine by turning or milling machines. This means that a lathe or milling cutter must be available, thereby increasing the cost of making the weld surfaces. In addition, the assembly of the welding machine tube tubes does not guarantee the parallelism of the tube welding surfaces. In addition, knife assemblies mounted on two parallel rolls are used to form weld surfaces on pipes made of plastics clamped on a welding machine. With this device, the welding surfaces are made manually and the interrupted rotational movement is effected by means of a ratchet and pawl mechanism. An advantage is the slow fabrication of welded surfaces and the impossibility of producing welded flat surfaces for inclined pipe welds. Also, parallel circular saws are used to produce the face weld surfaces on the plastic tubes clamped on the welding machine, which, if plugged in by the pipe ends, have progressively made both weld surfaces. A disadvantage is that rotary saws need to be used at least twice the diameter of the pipes and, in addition, in the course of the pipe processing, the saws have been rotated, especially when they are overheated. Welded surfaces on plastic pipes, on both sides at the same time, are also made of rotating milling cutters located on the top so that rotating cutters create parallel surfaces. and not suitable for welding. Making welded surfaces on a plastic pipe on a welding machine or using a laser beam gives excellent results, but in view of the expensive equipment and increased safety requirements of using a laser beam, this is a non-economical use.
Zariadením na zhotovovanie čelných zva-rových ploch na rúrach z plastov podl’a vy-nálezu sa uvedené nevýhody do značnej mie-ry odstránia. Zariadenie má na podstavci o-točne uchytené rameno ukončené objímkou,v ktorej je uložený prvý hriadel’, na ktoromsú uchytené válcové frézy. Druhý koniecprvého hriadefa je rotačně uložený v objím-ke odnímatefnej z ramena. Přitom rotačnýpohyb fréz je odvodený od elektromotorauchyteného v ďalšej objímke, v ktorej jeumiestnený druhý hriadel, na ktorého vof-nom konci je osadená prvá remenica s klí-novým remeňom, ktorý je uložený tiež nadruhej řemenici stabilně uchytenej na prvomhriadeli a toto ako celok je opatřené kry-tom. Ďalej na ramene je uchytená jedna ru-kováť a na elektromotore je uchytená druhárukováť, v ktorej je ovládacie tlačidlo.The disadvantages of the above-mentioned disadvantages are eliminated by the device for producing the front weld surfaces of the plastics tubes according to the invention. The device has a support arm attached to the base ending with a sleeve in which the first shaft is mounted, to which the cylindrical cutters are attached. The second end shaft is rotatably supported in a removable sleeve from the arm. In this case, the rotary movement of the milling cutters is derived from an electromotor mounted in another sleeve, in which a second shaft is mounted, at the top of which a first pulley with a key belt is mounted, which is also supported by a second pulley stably mounted on the first shaft and provided with a cover. -tom. Furthermore, one arm is attached to the arm and a second warranty is attached to the electric motor, which has a control button.

Dosahuje sa vysoká hladkostzvarových ploch u oboch zváraných rúr, za-ručuje sa symetrické uloženie v objímkáchzváracieho stroja. Příklad prevedenia vynálezu je znázorně-ný na připo j enom výkrese, kde obrázok před-stavuje zariadenie na zhotovovanie čelnýchzvarových ploch na rúrach z plastov podlávynálezu.Several advantages are achieved by the invention, and a separate machine tool saves either the seam or the milling cutter, eliminating the need to adjust the parallelism of the weld surfaces of the welded tubes. High smoothness of the welded surfaces is achieved in both welded tubes, ensuring a symmetrical fit in the welding machine sleeve. An example of an embodiment of the invention is shown in the accompanying drawing, in which the figure is a device for producing frontal surfaces on plastics pipes of the invention.
Zariadenie podlá vynálezu má na podstav-ci 2 otočné uchytené rameno 1 ukončenéobjímkou 3, v ktorej je uložený prvý hriadel’4, na ktorom sú uchytené válcové frézy 5.Druhý koniec prvého hriadefa 4 je rotačněuložený v objímke 6 odnímatefnej z ramena 1. Přitom rotačný pohyb fréz 5 je odvodenýod elektromotora 7 uchyteného v objímke 8,v ktorej je umiestnený druhý hriadel’ 9, naktorého vofnom konci je osadená prvá re-mehica 10 s klínovým remeňom 11 uloženýmtiež na druhej řemenici 12 stabilně uchyte-nej na prvom hriadeli 4 a toto ako celok jeopatřené krytom 16. Ďalej na ramene 1 jeuchytená jedna rukováť 13 a na elektromo-tore 7 je uchytená druhá rukováť 14, v kto-rej je ovládacie tlačidlo 15.The device according to the invention has a rotatably mounted arm 1 on the base 2, terminated by a sleeve 3, in which the first shaft 4 is mounted, on which the cylindrical cutters 5 are attached. The second end of the first shaft 4 is rotatably mounted in a sleeve 6 removable from the arm 1. the movement of the milling cutters 5 is derived from the electric motor 7 fixed in the sleeve 8, in which the second shaft 9 is located, on which the first reel 10 with the wedge belt 11 mounted also on the second pulley 12 stably mounted on the first shaft 4, and this In addition, one handle 13 is attached to the arm 1 and a second handle 14 is attached to the electric motor 7, in which the actuating button 15 is attached.
Do objímky 18 sa volné uloží rúra 17, po-tom sa favou rukou uchopí rukováť 14 uchy-tená na elektromotore 7 a pravou rukou sauchopí rukováť 13 uchytená na ramene 1.Potom sa rameno 1 s frézami 5 sklopí tak,že frézy 5 sú přibližné v střede rúry 17. Rú-ra 17 sa posunie na doraz s frézami 5 a urobísa značka na rúre 17 v mieste dotyku s ob-jímkou 18, pričom frézy 5 nerotujú. Potomrameno 1 s frézami 5 sa vrátí do východzejpolohy a rúra 17 sa posunie o vzdialenosťpotrebnú pre jej orezanie vzhfadom na uro-benú značku a rúra 17 sa v tejto polohe pev-ne uchytí v objímke 18. Potom sa opáť ru-kami uch opia rukováte 13 a 14 a rameno 1s frézami 5 sa přiblíží k povrchu rúry 17s ovládacím tlačidlom 15 sa privedie elek-trický prúd do elektromotora 7 a prostred-níctvom prvej řemenice 10, klínového remeňa11 a druhej řemenice 12 sa uvedú frézy 5do rotácie. Plynulým sklápaním ramena 1a tým i rotujúcich fréz 5, tieto sa dostanúdo záběru s rúrou 17 a vytvoria na nej sú-bežným frézováním zvarovú plochu. Tak istosa zhotoví zvarová plocha aj na druhej rúre.The tube 17 is placed loosely in the sleeve 18, and the sleeve 14 is then gripped by the hand grip on the electric motor 7 and the right hand grips the sleeve 13 attached to the arm 1. Then the arm 1 with the milling cutter 5 is tilted so that the milling cutters 5 are approximate in the center of the pipe 17. The pipe 17 is moved to the stop with the milling cutter 5 and makes a mark on the pipe 17 at the point of contact with the shell 18, whereby the milling cutters 5 do not rotate. The arm 1 with the milling cutter 5 is returned to the starting position and the tube 17 is moved by the distance needed for its trimming relative to the mark and the tube 17 is fixedly fixed in the sleeve 18 in this position. and 14 and the arm 1 with the milling cutters 5 approach the surface of the tube 17 with the actuating button 15, the electric current is supplied to the electric motor 7 and the rotary milling cutters 5 are brought through the first pulley 10, the V-belt 11 and the second pulley 12. By continuously tilting the arm 1a by the rotating milling cutters 5, they engage the tube 17 and form a welded surface on the tube 17 by routing it. This is how the weld surface is made on the other pipe.
