FLUX COATER FOR COATED ARC WELDING ROD

摘要

PURPOSE:To enable extremely easy exchange of die blocks in short time by disposing many die blocks to be provided at the top end of a flux discharging part into a turret type. CONSTITUTION:A die block 12 is held to the top end of the flux discharging part of a flux extruder 2 in tight contact therewith by means of a clamping device 11 which is actuated to open or close in parallel with the top end face thereof. A fulcrum shaft 14 intersecting orthogonally to said top end face is provided near the block 12 and a rotary plate material 13 is attached to the front end side of said shaft. the shaft 14 is axially movably and loosely supported to a bearing 16 attached to the extruder 2 by means of a bracket 15. The plural blocks 12 are attached to the plate 13 apart at a specified distance from the central point of rotation on the same plane. The exchange of the block 12 is accomplished by opening the device 11, actuating a cylinder 17 to extrude the shaft 14 and to detach the block 12 from the extruder 2, rotating the material 13 to bring the spare block 12a to the block 12 position and retreating the shaft 14 then holding the block 12a to the extruder 2 by means of the clamp 11 in tight contact therewith.
