| 摘要 | In order to remove flash from a weld of butt-welded sections of rod, four eccentrically mounted cutting wheels are positioned around the periphery of the rod adjacent to the weld. Each wheel has a plurality of cutting blades attached thereto which have paths of movement that overlap the paths of movement of other blades positioned on adjacent wheels when the blades are in cutting engagement with the flash. Each wheel is relieved along a chord thereof to form a straight section for initially accommodating the welded sections of rod before the milling operation is commenced. The eccentric mounting arrangement results in progressively deeper milling of the flash as the wheels are rotated. | ||||||
| 权利要求 | 1. An apparatus for removing material from a predetermined portion of the periphery of a workpiece, which comprises: means for holding a predetermined portion of a workpiece from which material is to be removed in a fixed predetermined position; a plurality of cooperating cutting elements disposed adjacent to the predetermined position in which the portion of the workpiece is adapted to be positioned, each of said cutting elements having at least one rigid material-removing means thereon adapted to project toward the predetermined position in which the portion of the workpiece is designed to be positioned; the material-removing means on said adjacent cooperating elements being staggered with respect to each other, and means for moving the material-removing means through predetermined arcuate paths of travel, the path of travel of said material-removing means on at least one of the cutting elements extending into the path of travel of at least one of the adjacent material-removing means on at least one of the other cooperating cutting elements so that the paths of travel of adjacent portions of the adjacent cooperating materialremoving means overlap while removing material from the predetermined portion of the workpiece and the inner boundaries of portions of the paths of travel of the material-removing means cooperate to define the desired contour of the outer periphery of the portion of the workpiece from which the material is removed. 2. The apparatus of claim 1 wherein said cutting elements are wheels relieved along chords thereof to facilitate insertion of the workpiece in said fixed predetermined position. 3. The apparatus of claim 1 wherein the cutting elements are disposed around the entire periphery of the workpiece and the paths of travel of the material-removing means of each of the adjacent cutting elements overlap each other so as to remove material from the entire periphery of the predetermined portion of the workpiece. 4. The apparatus of claim 1 wherein said cutting elements are disposed at 90* intervals around the periphery of the workpiece and wherein the material-removing means on said cutting elements which are diametrically opposed are also directly opposed when said paths of travel thereof bring said material-removing means into engagement with the workpiece to support the workpiece while the material is being removed. 5. The apparatus of claim 1 wherein said means for moving the material-removing means through predetermined paths of travel further includes means for advancing successive material-removing means on each cutting element closer to the axis of the workpiece as the material-removing means progress through the predetermined position in which the portion of the workpiece from which the material is to be removed is being held. 6. The apparatus of claim 5 wherein the cutting elements are eccentrically mounted wheels adapted to advance successive material-removing means closer to the axis of the workpiece. 7. The apparatus of claim 6 wherein said wheels are relieved along chords thereof to facilitate insertion of the workpiece in said fixed predetermined position. 8. The apparatus of claim 1 wherein each material-removing means is a blade terminating in a cutting edge for removing material from the workpiece. 9. The apparatus of claim 8 wherein said cutting edges of each of said blades have concave configurations which cut a series of interconnecting convex surfaces on said predetermined portion of said workpiece. |
