Abstract

By a method for bending elements of bar material, e.g. rods for reinforcing concrete, and which is peculiar in that a clamping means (13, 14; 13, 15) within the area of a bending core (11) is brought to clamp the bar material during the bending operation, preferably in immediate vicinity of the centre of a bending disc (12), there is achieved a minimum of waste material after the last bending operation to which a rod is subjected.

Description

Patentkrav . 1. Fremgangsmåde ved bukning af stangformet materiale, hvor et stangmateriale tilføres et bukkeværktøj ved hjælp af fremfø¬ ringsorganer, fastholdes af et klemorgan under en bukkeopera¬ tion og bukkes til elementer ved hjælp af et bukkeværktøj, der består af et bukkehjerte (11) med en central stangkanal og en herom på en bukketallerken (12) i afstand fra dennes centrum monteret bolt med en derpå drejeligt lejret bukkerulle (3), kendetegnet ved, at klemorganet (13,14; 13,15) bringes til indenfor bukkehjertets (2) område at fastklemme stangmaterialet under bukkeoperationen, fortrinsvis i umiddel¬ bar nærhed af bukketallerkenens (12) centrum. (Se fig- 5) 2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at klemmeoperationen sker ved hjælp af et eller flere klemorganer. 3. Bukkeværktøj til udøvelse af fremgangsmåden ifølge krav 1 eller 2, hvilket bukkeværktøj omfatter en roterbar bukketaller¬ ken (12) og et ved dennes centrum monteret med central stang¬ kanal forsynet bukkehjerte (11), der kan fastholdes udrejeligt i en given stilling, hvorhos bukketallerkenen (12) med en på en bolt drejeligt lejret bukkerulle (3) kan rotere, kende¬ tegnet ved, at der i bukkehjertet (11) er monteret mindst ét klemorgan (13,14; 13,15) til fastklemning af det stangma¬ teriale, der skal bukkes i bukkeværktøjet. (Se fig.5) 4. Bukkeværktøj ifølge krav 3, kendetegnet ved, at der i stangkanalens ene side opstrøms for klemorganerne (13, 14; 13,15) er anbragt en vinkelret på stangkanalens bund forløbende skarp kantdel (17), fortrinsvis af hærdet stål, til samvirken med det af klemorganerne, der er ved kanalens modsatte side.Patent claims. A method of bending rod-shaped material, wherein a rod material is applied to a bending tool by means of feeding means, is held by a clamping means during a bending operation and is bended to elements by means of a bending tool consisting of a bending heart (11). a central rod channel and one on a bending plate (12) spaced apart from its center bolt by a pivotally mounted bending roller (3), characterized in that the clamping means (13,14; 13,15) is brought within the bending heart (2) area to clamp the rod material during the bending operation, preferably in the immediate vicinity of the center of the bending plate (12). (See Fig. 5) 2. A method according to claim 1, characterized in that the clamping operation is performed by one or more clamping means. A bending tool for performing the method according to claim 1 or 2, which bending tool comprises a rotatable bending plate (12) and a bending heart (11) provided at its center mounted with a central rod channel, which can be extensibly held in a given position, wherein the bending plate (12) can rotate with a bending roller (3) pivotally mounted on a bolt, characterized in that at least one clamping member (13,14; 13,15) is mounted for clamping the rod wall (11) ¬ material to be bent in the bending tool. (See Fig. 5) 4. A bending tool according to claim 3, characterized in that a sharp edge portion (17), perpendicular to the bottom of the rod channel, is arranged perpendicular to the bottom of the rod channel (13), preferably by hardened steel, for interaction with that of the clamping members which are at the opposite side of the duct.
