WELDING WIRE PULSE FEED MECHANISM Russian patent published in 2005 - IPC

Abstract RU 2254969 C1

FIELD: technological welding equipment, namely attachments for pulse feed of welding wire to welding zone.

SUBSTANCE: mechanism includes two clamps 1,2 for wire 3; rod 4 whose axis is normal relative to axis of wire passing through opening 5 in mean portion of rod; apparatus for reciprocation motion of rod in axial direction. Said apparatus is in the form of compression spring 6 secured to one end of rod. Other end of rod is provided with rollers 7 and it engages with disc cam 8 driven to rotation. Spacing between clamps 1, 2 is adjusted by means of screws 10 with right-hand and left-hand threads joined through clutch 12.

EFFECT: simplified design, enhanced operational reliability of mechanism.
