摘要:
The claimed device for removing flash from the seams of buttwelded long-measure articles includes a casing carrying a head with opening cutters, said head being installed with a provision for being moved progressively by its drive on a lever one end of which is articulated at the base of the casing and connected with the drive which turns said lever in a vertical plane for bringing the lever with the head to a working position parallel to the article.
摘要:
A welding unit for welding rails of a track includes a shearing device for removing a weld bead. The shearing device includes a head part having a shearing edge and two side parts which are pivotable towards one another and have a shearing edge. A rail base section to be applied to a rail base is associated with each side part. The rail base sections each include an end region facing towards each another having a tooth system for a form-locking connection which is effective in a longitudinal direction of the rail after the two side parts have been applied to the rail.

The base of the apparatus has the form of a claw clamp with two grips for gripping a rail that are kinematically linked with a clamping cylinder. The apparatus incorporates an upper cutter and side cutters, mounted so that, with the claw clamp closed, the cutting edges of the cutters form an outline embracing the cross-sectional perimeter of the rail. Each side cutter is hinged to the respective grip and mounted thereon for a displacement parallel to the axis of symmetry of the outline formed by the cutting edges of the cutters. The upper cutter is kinematically linked with the rod of the clamping cylinder via a clearance take-up mechanism which provides for lifting the upper cutter and the side cutters hinged thereto to engage the side cutters with the rail foot underside.
摘要:
A device for removing flash from rails after resistance butt welding, mounted on a welding machine case and split along the vertical axis of the rail, comprising three cutters embracing the rail along the entire cross-sectional perimeter thereof and coupled with a hydraulic cylinder drive, one of said cutters is pivotally mounted on said case, split along the vertical axis thereof and contacts the rail rolling surface, while the two side cutters which embrace the sides of the rail head, the web and the base flange of the rail are arranged symmetrically relative to the vertical axis of the case and hinged thereto, the top portions of said side cutters being linked by an articulated rod.
