Abstract

Menetelmä teräksisten metallitankojen (1) päähän muodostettavan laajennuksen, kuten betonitartuntojen päähän muodostettavan kartiomaisen laajennuksen (10), tekemiseksi, jossa&sr;- tangon (1) pään aluetta (4) kuumennetaan hallitusti aloittamalla kuumennus alueen (4) tangon päähän (5) nähden vastakkaisesta kohdasta (6) ja lisäämällä lämmitystä tangon päätä (5) kohti nousevaan lämpötilaan, ja&sr;- kuumennettu tanko (1) lukitaan liikkumattomaksi ja sitä puristetaan tangon päästä (5), joka on järjestetty välimatkan päähän muotista/vasteesta (2), alkaen puristuslevyllä (3) tai vastaavalla puristusosalla kohti muottia/vastetta (2), jolloin tangon pään alueen osien (5, 6) välillä esiintyvien lämpötilaerojen vaikutuksesta tyssääntyminen ohjataan alkamaan tangon (1) kuumimmasta päästä (5) ja etenemään kohti tangon alenevan lämpötilan aluetta (6) aikaansaaden erityisesti edellytykset tangon pään alueen (4) optimaaliseen muotoutumiseen.&sr;Fig. 1A method for making an extension to be formed at the end of steel metal rods (1), such as a conical extension (10) to be formed at the end of concrete adhesions, wherein&sr;- the end region (4) of the rod (1) is heated in a controlled manner by starting the heating of the region (4) from a point (6) opposite the rod end (5) and increasing the heating towards the rod end (5) to a temperature that increases, and&sr;- the heated rod (1) is locked immobile and pressed against the rod end (5) arranged at a distance from the mold/stop (2), starting with a pressing plate (3) or a similar pressing part towards the mold/stop (2), whereby the quenching is guided by the effect of the temperature differences between the parts (5, 6) of the rod end region to start at the hottest end (5) of the rod (1) and to proceed towards the area (6) of decreasing temperature of the rod, in particular providing conditions for the rod end region (4) for optimal shaping.&sr;Fig. 1
