Abstract
A chain welding machine for the electrical resistance butt-welding of subntially C-shaped chain links is disclosed wherein two pair of electrodes are arranged symmetrically in relation to a median plane of the machine frame. Each pair of electrodes is supported on a pair of double-armed levers arranged for opposite rotation about a horizontal axis. Each electrode pair is adapted to grip, in plier-like fashion, one of the two ends of the chain link to be welded. Each lever pair is rotatably mounted to a trunnion which is, in turn, resiliently mounted in a bushing in the machine frame for absorbing any radial and/or axial loads imposed on the electrodes by misaligned or oversized chain links to be welded.
Claims27
A chain welding machine for the electrical resistance butt-welding of inter-linked chain links bent into approximate C-shape comprising:
- a machine frame having a vertical median plane;
- two bushings mounted to said machine frame along horizontal axes and symmetrically with respect to said median plane;
- a trunnion disposed in each bushing;
- means resiliently mounting each trunnion in its respective bushing along the horizontal axis thereof;
- two pair of double-armed levers arranged symmetrically with respect to said median plane, the levers of each lever pair being rotatably mounted to a respective one of said trunnions for rotation in opposite directions about the axis of said respective trunnion;
- and
- an electrode supported by each lever and arranged to grip a respective one of the two ends of the chain link to be welded in a plier-like manner.
