Embodiment Construction

[0017] The fracture welding and crack repair of the band saw blade of the present invention are mainly carried out by the welding process, and the frocks used during the welding are as follows: figure 1 , figure 2 As shown, the tooling includes a backing plate 1 for padding the lower part of the band saw blade. The upper end surface of the backing plate 1 is a working surface, and a groove 2 is opened in the middle of the working surface of the backing plate 1. On the working surface A pressing device for fixing the fracture portion of the band saw blade is respectively provided near the edges of both sides of the groove 2. In this embodiment, the pressing device includes bosses 3 respectively protruding from the working surfaces on both sides of the groove. , the height of the two bosses 3 is equivalent to the thickness of the band saw blade to be repaired, the extension direction of the two bosses 3 is perpendicular to the groove 2, and the two bosses 3 are vertically insta...

Abstract

According to a fracture welding method of a band saw blade disclosed by the invention, a burn fusion welding way is mainly utilized, a fused liquid obtained after the fracture of the band saw blade is fused is utilized to weld by bonding, and other metal welding rods and fluxes are not needed in the welding process. The fused liquid obtained after the band saw blade is fused is utilized to bond two sections of the band saw blade, a welding seam of the band saw blade is smooth, welding beading and welding slag are not produced, a welding part is not reground, and the annealing problem of the band saw blade in the regrinding process is avoided. Additionally, the thickness of the welding part conforms to the thickness of the band saw blade, the tensile strength of the welding part is high, the toughness of the welding part conforms to the toughness of the band saw blade, and the crack repairing problem of the band saw blade is effectively solved by using the burn fusion welding way.

Description

technical field [0001] The invention belongs to the field of metal welding, and more precisely relates to a band saw blade fusion welding method and a band saw blade welding fixture for implementing the method. Background technique [0002] Metal band saw blade welding generally adopts silver welding method, brazing method or butt welding method: silver welding method is to apply borax and other flux on silver welding rod, and weld the fracture of band saw blade together; brazing method is to use copper welding rod plus welding The method of welding the band saw blades of high manganese steel together; the butt welding method is to install the incision of the band saw blade to be welded on the butt welding machine, use a large current to melt the metal at the welding part, and use mechanical butt joint Pressure to bond the melted parts of the band saw blade together. Whether it is silver welding, brazing or butt welding, welding nodules and welding slag will be produced at ...
