Abstract
The high efficiency welding device has two pairs of clamps mounted in two pairs of sliders movable in a reciprocating movement relative to one another. One pair of sliders is mounted at 0 and 180 degree positions around the circumferential surface of a support block and the other pair of sliders is mounted at 90 and 270 degree positions. Each pair of clamps is in the close condition while moving forward in the reciprocating movement to clamp onto selected air gaps of the welding electrode to advance the electrode towards the work piece as well as delivering the welding current to the welding operation, and it is in the open condition releasing the grasp of the welding electrode while moving backward.
Claims11
A high efficiency welding device for a continuous welding electrode having equal length welding flux coating sections separated by evenly spaced consecutive air gaps exposing a metal core within said electrode, comprising:
- two pairs of clamps mounted within two pairs of sliders, a first pair of said sliders being slidably mounted within first two tracks formed on a circumferential outer surface of an elongated support block, said first two tracks being located directly opposite to one another and lying in a first plane perpendicular to the longitudinal axis of said support block, a second pair of said sliders being slidably mounted within second two tracks formed on said outer surface of said elongated support block, said second two tracks being located directly opposite to one another and lying in a second plane perpendicular to both said first plane and the longitudinal axis of said support block;
- a central opening formed in the longitudinal axis of said support block operative for receiving said continuous welding electrode to pass through said device;
- two coupling members movable in a back and forth reciprocating movement relative to one another, one coupling member being connected to said first pair of sliders and a second coupling member being connected to said second pair of sliders;
- first pair of clamps of said two pairs of clamps being located in said first pair of sliders, and a second pair of clamps of said two pairs of clamps being located in said second pair of sliders, said first pair of clamps and said second pair of clamps being located alternately at a front position and rear position relative to one another in said reciprocating movement, and alternately grasping on said welding electrode while moving forward to said front position, and releasing the grasp on said welding electrode while moving rearward to said rear position.
A high efficiency welding device for a continuous welding electrode having equal length welding flux coating sections separated by evenly spaced consecutive air gaps exposing a metal core within said electrode, comprising:
- a support block mounted at a front end portion of said device, said support block having a cross-shape cross sectional shape with four U-shaped tracks formed around circumferential surface of said support block at 0, 90, 180 and 270 positions and extending the entire longitudinal length thereof, said tracks at said 0 and 180 positions being located in a first plane perpendicular to the longitudinal axis of said block, said tracks at said 90 and 270 positions being located in a second plane perpendicular to the longitudinal axis of said block as well as perpendicular to said first plane;
- a central through opening extending throughout the entire longitudinal center axis of said support block and operative for said welding electrode to pass therethrough in said device,
- a U-shaped slider slidably mounted in each of said four U-shaped tracks, said slider being movable in a reciprocating movement with respect to each respective track, and said slider in the tracks at said 0 and 180 positions being moved in an opposite direction to said slider in the tracks at said 90 and 270 positions;
- two coupling members movable in a back and forth reciprocating movement relative to one another, one coupling member being connected to a first pair of sliders at said 0 and 180 positions, and a second coupling member being connected to a second pair of sliders at said 90 and 270 positions;
- clamping means mounted in said slider, said clamping means being in a closed condition for grasping said welding electrode during forward movement of said slider to a front position, and being in an opened condition releasing from said welding electrode during rearward movement of said slider to a rear position, said clamping means in said first pair of sliders and said second pair slider being in said closed condition and opened condition alternately opposite to one another during reciprocating movement of said first pair of sliders and said second pair of sliders.
