| 摘要 | An automatic rotary swaging machine for reducing parts from wire, such as bycycle spokes and the like, providing continuous operation without time losses for idle runs so as to enhance its efficiency, comprising a reducer head for swaging the wire, a continuous wire feed mechanism and a cut-off mechanism for cutting the reduced part during the motion of the wire wherein the continuous feed of wire, in combination with a cut-off of the reduced part, provides for a highly efficient automatic rotary swaging machine and a high quality for the produced parts. | ||||||
| 权利要求 | 1. An automatic rotary-swaging machine for reducing metal-wire parts, preferably bicycle spokes, comprising: a machine bed; a reducer head located on said bed; an outer spindle arranged in said reducer head; an inner spindle accommodated inside said outer spindle and adapted to rotate cooperatively therewith; a working tool held in said outer and in inner spindles; a mechanism for cutting-off finished parts, said mechanism being mounted on said bed and being in operative connection with said reducer head; a cut-off tool held in a body fixed on a saddle of said mechanism including a gear worm pair mounted on said saddle for cutting-off finished parts; a mechanism to feed said metal wire through said reducer head into mentioned mechanism for cutting off finished parts, said wire-feed mechanism being operatively connected with said reducer head and with said cutoff mechanism via said outer spindle of the afore-mentioned reducer head; said wire-feed mechanism including an endless conveyer for feeding said metal wire, said conveyer being mounted on a fixed base located on said machine bed; clamping fixtures fixed in position on said endless conveyer to ensure a continuous feeding of said metal wire. 2. An automatic rotary-swaging machine as claimed in claim I, wherein said endless conveyer of the mentioned wire-feed mechanism is made essentially as a chain conveyer. 3. An automatic rotary-swaging machines as claimed in claim I, wherein each of the afore-said clamping fixtures comprises a spring member and two clamping jaws of which one is mounted on a first body rigidly connected to the endless conveyer, the other jaw being located on another body mounted pivotably with respect to an axle made fast in the former body; said spring member being adapted to bring said jaws in contact with each other; the latter of the afore-mentioned bodies carrying a roller adapted to interact with a fixed guide block mounted on a stationary base of said endless coneyer. 4. An automatic rotary-swaging machine as claimed in claim 2, wherein each of the afore-said clamping fixtures comprises a spring member and two clamping jaws of which one is mounted on a first body rigidly connected to the endless conveyer, whereas the other jaw is located on another body mounted pivotably with respect to an axle made fast in the former body; said spring member being adapted to bring said jaws in contact with each other; the latter of the afore-mentioned bodies carrying a roller adapted to interact with a fixed guide block mounted on a stationary base of said endless conveyer. 5. An automatic rotary-swaging machine as claimed in claim I, wherein the body of the mechanism for cutting-off finished parts is mounted on a saddle operatively interconnected with the outer spindle of the reducer head, and with a worm-and-worm wheel through the agency of which a set-up motion of said body is attainable. 6. An automatic rotary-swaging machine as claimed in claim 2, wherein the body of the mechanism for cutting off finished parts, is mounted on a saddle operatively interconnected with the outer spindle of the reducer head and with a worm-and-worm wheel through the agency of which a set-up motion of said body is attainable. 7. An automatic rotary-swaging machine as claimed in claim 3, wherein the body of the mechanism for cutting off finished parts, is mounted on a saddle operatively interconnected with the outer spindle of the reducer head and with a worm-and-worm wheel through the agency of which a set-up motion of said body is attainable. |
