Description
(54) Perforované plechy tvarované pre žiaruvzdorné stavivá(54) Perforated sheets shaped for refractory building materials
Perforované plechy s mechanickým uhlovým dorazom pre bázické žiaruvzdorné stavivá s chemickým viazaním v peci spadá do oboru keramického a hutnického priemyslu, kde rieši obalovanie stavív plechmi pri ich výrobě, resp. už vyrobených. Podstatou riešenia takýchto pleehov sú perforácie pre jednoduché a přesné ohýbanie a výstupky, slúžiace ako doraz pri ohybe na dosiahnutie stanoveného uhla ohybu.Perforated sheets with mechanical angular stop for basic refractory building materials with chemical bonding in the furnace belong to the field of ceramic and metallurgical industry, where they deal with coating of building materials with metal sheets during their production, resp. already made. The essence of the solution of such skins are perforations for simple and accurate bending and projections, serving as a stop at the bending to reach the specified bending angle.

Vynález rieši perforované plechy, tvarované pre žiaruvzdorné stavivá s chemickým viazaním v peci, kde tleto stavivá tvoria výmurovku.SUMMARY OF THE INVENTION The present invention provides perforated sheets shaped for refractory building materials with chemical bonding in an oven, where the building materials form a liner.
Doterajšie vyhotovenia plechových obalov sú riešené kusovo, t. j. pre každú stenu staviva, alebo sú ohnuté do tvaru písmena „L“ pre obalenie dvoch stien staviva. Takéto tvary plechov sa vkladajú do formy a pri výrobě lisováním sa s ním mechanicky spoja, alebo u hotových stavív sa spojenie prevádza prostredníctvom lepidla.Existing embodiments of sheet metal packaging are solved in one piece, i. j. for each wall of the building material, or are bent to the shape of the letter "L" to wrap two walls of the building material. Such sheet shapes are inserted into the mold and are mechanically bonded to it during compression molding, or in the case of ready-to-use construction materials, the joint is bonded by means of an adhesive.
Podstata riešenia podta vynálezu spočívá v tom, že perforácia na plechu je vytvořená v tom mieste, kde sa bude ohýbat, a to buď ručně, alebo automaticky do uhla zovretia, ktorý je daný výstupkami z plechu. Po ohnutí do daného uhla tleto výstupky sú o seba opreté, čím zamedzujú ďalší ohyb v perforovanom mieste.The principle of the solution according to the invention is that the perforation on the sheet is formed at the point where it will be bent, either manually or automatically to the clamping angle given by the projections of the sheet. Upon bending at a given angle, the projections are supported on each other, thereby preventing further bending at the perforated location.
Popísanou konštrukciou plechu sa dosahuje fyzicky nenáročný ohyb v presne stanovenom mieste, čo zabezpečuje perforácia a dosahuje sa přesný uhol ohybu, ktorý je vymedzený výstupkami z plechu. Ďalšou výhodou je zaručená přesnost uloženia vo formě lisu v procese výroby staviva.The described sheet metal design achieves a physically undemanding bend at a precisely defined location, which provides perforation and achieves a precise bending angle defined by the sheet metal projections. Another advantage is the guaranteed accuracy of the press fit in the construction process.
Jedno z riešení plechov vyhotovených podl'a popísaného vynálezu je zobrazené na přiložených výkresoch, kde na obr. 1 je nárys perforovaného plechu s mechanickým uhlovým dorazom, na obr. 2 je znázorněný čiastočný priečny rez plechu po ohnutí jeho okrajov do tvaru písmena „U“ v mieste perforácie do stanoveného uhla, ktorý je vymedzený dorazom výstupkov, na obr. 3 je čiastočný rez v mieste A—A, na obr. 4 je čiastočný rez plechu v mieste Β—B.One of the sheet metal embodiments of the present invention is shown in the accompanying drawings, in which: FIG. 1 is a front view of a perforated sheet with a mechanical angle stop; FIG. 2 is a partial cross-sectional view of the sheet after bending its edges into a " U " shape at the perforation to a predetermined angle defined by the projection stop; FIG. 3 is a partial cross-section at A-A; FIG. 4 is a partial cross-sectional view of the sheet at Β — B.
Perforácia 1 je vytvořená v mieste budúceho ohybu na obalovom plechu, ktorý má obrysový tvar podl'a druhu staviva s výstupkami ,2, pre mechanickú vazbu plechu s báziským stavivom pri lisovaní stavív. Výstupky 3 a výstupky 4, sú vyhotovené zastřihnutím plechu pre dosiahnutie stanoveného uhla ohybu v mieste perforácie 1. Umiestnenie výstupkov 3, 4 voči perforácii 1 je zázislé od uhla ohybu a dížky výstupku 3.The perforation 1 is formed at the location of the future bending on the envelope sheet having a contour shape according to the type of the building material with the protrusions, 2, for mechanically bonding the sheet with the basic building material when pressing the building materials. The projections 3 and projections 4 are made by trimming the sheet to achieve a predetermined bending angle at the perforation 1. The location of the projections 3, 4 relative to the perforation 1 is dependent on the bending angle and the length of the projection 3.
Předložený vynález je možné využit v keramickom a hutníckom odvětví na obalovanle stavív plechom pri ich výrobě, alebo už vyrobených stavív, pričom výrazné zmenšuje prácnosť velkého počtu plechov na jedno stavivo pri dopravě plechov, výrobě a manipulácii, skracuje čas jedného pracovného cyklu.The present invention can be used in the ceramic and metallurgical industry for the coating of sheet metal construction materials in their manufacture or already manufactured construction materials, while significantly reducing the workload of a large number of sheets per sheet material in sheet transport, manufacturing and handling, shortening one cycle time.
