WELDING WIRE IMPULSE FEED MECHANISM Russian patent published in 1999 - IPC

FIELD: mechanical engineering; welding facilities. SUBSTANCE: housing 1 accommodates two electromagnetic coils 5 and 7 with armatures 6 and 8 and two clamps 11 and 16 for wire 12, two damping inserts 9 and 10 and two cores 2 and 3. Core 3 is fixed in coil 7. Core 2 installed in coil 5 for reciprocating and fixing is rigidly coupled with clamp 11 for wire 12. Armatures 6 and 8 are provided with shanks 13 and 14 pointed to each other. Second clamps 16 for wire 12 is arranged between shanks 13 and 14 and is provided with casing 15. Each damping insert 9 and 10 is located between corresponding core 2, 3 and armature 6, 8. Mechanism has compression spring 17 located between casing 15 and coil 5. EFFECT: provision of uniform wire displacement force owing to creation of additional pulse energy at initial moment of wire movement. 1 dwg
