Abstract

Föreliggande uppfinning avser en anordning vid ett rörbockningsredskap (1), som uppvisar stödytor (2,2', 2") mellan vilka ett rör (3), som skall böjas är anbringbart för anläggning och tryck mot delar av rörets (3) mantelyta (4) för åstadkommande av en böj (5) på röret (3), vilket redskap (1) uppvisar en påtryckningsenhet (6) med ett utskjutbart utskott (8) mot röret (3), där en konvext böjd schablon (10) är anordnad att pressa mot rörets (3) mantelyta (4) då utskottet (8) tillförs en kraft från påt ryckningsenheten (6). Den främre delen (9) har två långsträckta element (12,12'), som är korslagda och ledbart anordnade i sina första ändar (13,13') för att under böjningen pressa i en riktning mot rörets (3) böjradie-centrum, varvid olika radier på böjen (5) på utvalda ställen är utförbara, vilka elements (12,12') motsatta ändar (14,14') uppbär förskjutbara mothåll (15,15') på var sin sida om schablonen (10), som pressar den tillförda kraften mot rörets (3) motsatta mantelyta (4'), då schablonen (10) pressar mot förstnämnda mantelyta (4) mer och mer, varvid röret (3) böjs i önskad omfattning både mellan och mot mothållen (15,15').The present invention relates to a device for a pipe bending tool (1), which has support surfaces (2,2 ', 2 ") between which a pipe (3) to be bent is attachable for installation and pressure against parts of the mantle surface (3) of the pipe (3). 4) for effecting a bend (5) on the tube (3), which tool (1) has a pressure unit (6) with a extendable projection (8) against the tube (3), where a convexly bent stencil (10) is arranged to press against the jacket surface (4) of the pipe (3) when the projection (8) is supplied with a force from the jerking unit (6) .The front part (9) has two elongate elements (12,12 '), which are crossed and articulated in its first ends (13,13 ') to press during bending in a direction towards the bending radius center of the tube (3), different radii of the bend (5) being selected at selected locations, which opposite ends (12,12') (14,14 ') support displaceable abutments (15,15') on each side of the stencil (10), which press the applied force against the opposite jacket surface (4 ') of the tube (3), when sch the ablone (10) presses against the first-mentioned mantle surface (4) more and more, the tube (3) being bent to the desired extent both between and against the abutments (15,15 ').
