Abstract
Two slidable carriages of identical construction are slidably mounted in a welding device side by side and move alternately 180 degrees out of phase with each other in a linear reciprocating movement. Pivotal gripping plates are mounted on the slidable carriages which alternately clamp on selected gaps between flux coating sections of the welding electrode to advance it continuously towards the work piece. Crank shafts are incorporated in the welding device to produce the linear reciprocating movement of the two slidable carriages, and cam wheels and pivotal bars are provided to locate alternately one group of gripping plates in the closed position to carry the welding electrode forward while the other group of gripping plates are in the opened position to facilitate the welding electrode to advance.
Claims11
A driving system for a welding device for use with a continuous welding electrode having equally spaced flux coating sections provided on a metal core comprising:
- a first slidable carriage and a second slidable carriage mounted within said welding device, said first slidable carriage and second slidable carriage being movable alternately in a linear reciprocating movement,
- first group of gripping plates mounted on said first slidable carriage, and being operative in a closed position to clamp on said metal core at selected gaps of said welding electrode when said first slidable carriage is in an advance movement in said reciprocating movement, and alternately in an opened position to release clamping of said welding electrode when said first slidable carriage is in a rearward movement in said reciprocating movement,
- second group of gripping plates mounted on said second carriage, and being operative in a closed position to clamp on said metal core at selected gaps of said welding electrode when said second slidable carriage is in an advance movement in said reciprocating movement while said first slidable carriage is in said rearward movement, and alternately in an opened positions to release clamping of said welding electrode when said second slidable carriage is in a rearward movement in said reciprocating movement while said first slidable carriage is in said advance movement.
A driving system for a welding device for use with a continuous welding electrode having equally spaced flux coating sections provided on a metal core, comprising:
- a first slidable carriage slidably mounted on a first mounting bolt in an enclosure of said welding device, said first slidable carriage having a main body portion and an elongated casing extending from a middle position of a front edge of said main body portion,
- a second slidable carriage slidably mounted on a second mounting bolt in said enclosure and located in parallel to said first slidable carriage, said second slidable carriage having a construction identical to said first slidable carriage,
- a first crank shaft mounted rotatably in said enclosure and said first slidable carriage, and being operative to cause a linear reciprocating movement of said first slidable carriage,
- a second crank shaft mounted rotatably in said enclosure and said second slidable carriage, and being operative to cause a linear reciprocating movement of said second slidable carriage,
- a third crank shaft mounted in said enclosure,
- connecting rods mounted between said first crank shaft and said third crank shaft and between said second crank shaft and said third crank shaft whereby operation of said third crank shaft cause said first slidable carriage and said second slidable carriage to move alternately in opposite directions in said linear reciprocating movement,
- a first elongated rotatable bar rotatably mounted in said elongated casing of said first slidable carriage, a second elongated rotatable bar rotatably mounted in said elongated casing of said first slidable carriage and located mutually parallel to said first elongated rotatable bar,
- a first group of gripping plates mounted on said first elongated rotatable bar and said second elongated rotatable bar and operative to grip said welding electrode at selected gaps therein when said first slidable carriage is in said advance movement, and releasing grip of said welding electrode when said first slidable carriage is in said rearward movement,
- a third elongated rotatable bar rotatably mounted in said elongated casing of said second slidable carriage, a fourth elongated rotatable bar rotatably mounted in said elongated casing of said second slidable carriage and located mutually parallel to said third elongated rotatable bar,
- a second group of gripping plates mounted on said third elongated rotatable bar and said fourth elongated rotatable bar, and being operative to grip said welding electrode at selected gaps therein when said second slidable carriage is in said advance movement while said first slidable carriage is in said rearward movement, and releasing grip of said welding electrode when said second slidable carriage is in said rearward movement while said first slidable carriage is in said advance movement.
