Abstract
(EN)
The invention relates to a piece for mechanical joining by means of screwing that can be used for resistance welding, which consists of a nut (1) or screw (1') intended to be welded to a plate (3) or similar by means of resistance welding using protuberances (4) on the joining surface (10) for joining to the plate (3). The joining surface, which belongs to the body of the nut in the case of a nut (1) and to the head of the screw in the case of a screw (1'), has a triangular shape in plan view, with three equal sides (L), and incorporates three identical protuberances (4) disposed in alignment with the three vertices (V) of the triangle. The vertices (V) are rounded, defined by segments of a circumference having a centre (o) that is coaxial with the centre of the piece (1, 1'), the protuberances (4) spanning the entire length of the segment and having a frustoconical cross-section.
(ES)
Consistente en una tuerca (1) o un tornillo (1') destinado a soldarse en una chapa (3) o similar, mediante soldadura por resistencia a través de protuberancias (4) en su superficie de unión (10) a la chapa (3), que en el caso de tratarse de una tuerca (1) pertenece al propio cuerpo de la misma y en el cado de tratarse de un tornillo (1') pertenece a la cabeza, la cual es de configuración plantar triangular, con tres lados (L) iguales, e incorpora tres protuberancias (4) idénticas situadas en coincidencia con los tres vértices (V) de dicha forma triangular. Los vértices (V) son redondeados, determinados por segmentos de circunferencia cuyo centro (o) es coaxial con el centro de la pieza (1, 1'), y las protuberancias (4) abarcan toda su extensión y tienen una sección troncocónica.
(FR)
L'invention concerne une pièce de liaison mécanique par vissage applicable pour le soudage par résistance, constituée d'un écrou (1) ou d'un boulon (1') destiné à être soudé sur une plaque (3) ou analogue, par soudage par résistance par l'intermédiaire de protubérances (4) sur sa surface de liaison (10) à la plaque (3), qui lorsqu'il s'agit d'un écrou (1) appartient au corps même de celui-ci et lorsqu'il s'agit d'un boulon (1') appartient à la tête, laquelle est de configuration planaire triangulaire, à trois côtés (L) égaux, et intègre trois protubérances (4) identiques. Les sommets (V) sont arrondis, déterminés par des segments de circonférence dont le centre (o) est coaxial avec le centre de la pièce (1, 1'), et les protubérances (5) englobent toute leur extension et présentent une section tronconique.
