Control device for flash-butt resistance welding machine

The arrangement comprises a body constructed in the form of a grip clamp arable from the vertical axis of a workpiece, and having two jaws coupled with each other in the upper portion thereof by a clamping cylinder. The arrangement further comprises cutters for deburring, and a mechanism for pressing said cutters to the workpiece surface. The cutters are mounted in the lower portion of the jaws so that cutting edges thereof form a profile of the workpiece cross-section. The cuttes disposed on the same jaw are pivotally connected with each other. The mechanism for pressing the cutters is constructed in the form of a system of hydraulic cylinders mounted on the jaws in symmetrical relationship relative to the vertical axis of the body. Said hydraulic cylinders are provided with rods operatively connected to corresponding cutters.

Arrangement for removing burrs in butt resistance welding of workpieces

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.
