Description

Electroslag welding wire butt joint device

Technical Field

The utility model belongs to the technical field of mechanical equipment makes, in particular to electroslag welding wire interfacing apparatus.

Background

In the welding and manufacturing of steel structural members, electroslag welding is commonly used for welding large-sized weldments, wherein most of the electroslag welding weldments have large welding quantity, so that a single coil of electroslag welding wire cannot meet the continuous welding requirement in welding (the welding wire cannot be replaced in the welding process, and the arc breaking phenomenon can be caused if the welding wire is not replaced in the welding process); therefore, a plurality of welding wires need to be butted before welding, the butt joint is required to be smooth, and the butt joint device is designed in order to conveniently and quickly butt joint the welding wires and ensure the smoothness of the joint.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an electroslag welding wire interfacing apparatus has solved among the prior art electroslag welding wire butt joint uneven problem.

The technical scheme adopted by the utility model is that the electroslag welding wire butt joint device comprises a bottom plate, two L-shaped upper pressing plates are arranged on the bottom plate side by side, a supporting table is also arranged on the bottom plate, and the middle part of the long edge of each L-shaped upper pressing plate is connected with the supporting table through a movable shaft; the position that is relative with two L type top board minor faces on the bottom plate still is provided with two lower back shafts, and in the minor face that lower back shaft stretched into L type top board, the tip on the long limit of L type top board passed through the spring and links to each other with the bottom plate.

The utility model discloses a characteristics still lie in:

wherein the L-shaped upper pressing plate is parallel to the bottom plate;

wherein a groove matched with the lower support shaft is arranged in the short edge of the L-shaped upper pressure plate;

wherein the bottom of the short edge of the L-shaped upper pressure plate is provided with a rotating shaft matched with the lower support shaft;

wherein the joint of the lower supporting shaft and the bottom plate is sequentially sleeved with a copper backing plate and a lower backing plate;

wherein the surface of the copper gasket is also provided with an arc groove;

wherein the outside of the joint of the spring and the bottom plate is also sleeved with a steel pipe seat.

The utility model has the advantages that:

the utility model discloses an electroslag welding wire interfacing apparatus makes electroslag welding wire butt joint back evenly send into welder fast, reaches the electroslag welding requirement, and the welding wire can be at the uniform velocity output when making things convenient for the electroslag welding, guarantees the welding needs, avoids the consuming time power that original welding wire butt joint brought and the not good problem of effect, increases work efficiency.
