In the field of ring processing, a ring band saw is generally adopted to cut a ring blank, and as the service time of the band saw blade is prolonged, the cutting edge of the band saw blade becomes blunt gradually or saw teeth are lost due to the action of external force, so that the band saw is likely to be broken. In order to better save the production cost, the detached band saw is used continuously after being repaired, and the band saw blade is usually welded again and then used, and special welding equipment is usually adopted for repairing the band saw blade at present, such as Chinese patent publication No.: CN 205342191U, publication date: in the welding flash butt welding machine for precisely welding the band saw blade in the year of 2016 and 29, the band saw blade is repaired by the special equipment, so that the repairing effect can be achieved, but for enterprises which do not specially produce and repair the band saw blade, the special equipment is purchased to repair the broken band saw blade obviously is uneconomic, the cost input is too high, and the equipment occupies more space to influence the production of original products of the enterprises.
Through searching, chinese patent publication number: CN 102672302A; publication date: 2012, 9 and 19 days; the utility model discloses a fracture welding and crack repairing method of band saw blade and supporting frock of welding, utilize the solution bonding that forms after the fracture of band saw blade was melted to weld with the mode of welding, the structure of frock of welding is including being used for the pad to establish the backing plate under the band saw blade, the up end of backing plate is the working face and set up flutedly at this working face middle part, the both sides mouth edge punishment that is close to the recess at the working face do not is equipped with the closing device that is used for fixed band saw blade fracture, movable mounting is used for the pad iron of pad setting under the fracture of band saw blade in the recess, the up end of pad iron flushes with the backing plate working face. Although this application provides a comparatively simple frock of structure and is used for the restoration of band saw blade, compares in current repair equipment with low costs, and area occupied is little, but when the frock and the restoration method of this application carry out band saw blade welding, because before welding band saw blade fracture shape is irregular, very easily fracture once more in the use after the welding, and band saw blade life is short after the restoration.

Cutting, namely placing a band saw blade to be repaired on a band saw blade supporting plate (27), abutting the edge of the saw blade against a guide plate (270), extending a fracture part to be cut out of a cutting notch (23), holding a handle (2623) to lift, and driving a lower blade (25) to lift to finish cutting;
2. Fixing, namely cutting two fractures of the band saw blade to be welded on a cutting position (2), respectively placing the cut fractures under a left pressing plate (32) and a right pressing plate (33) of a welding position (3), butting the two fractures at a V-shaped groove (321), abutting the edges of the band saw blade against a limit baffle (36), and rotating a screw rod to put down the left pressing plate (32) and the right pressing plate (33);
3. And (3) welding, namely after the band saw blade to be repaired is fixed on the welding position (3), welding by using a welding rod.
