Upset oil pipe bundling device and bundling method

The invention relates to an upsetting oil pipe bundling device and bundling method. The bundling device comprises semi-opening spacing battens, outer fixing battens, bundling steel belts and protective nails. A plurality of pairs of slot openings are formed in the half-opening spacing battens at intervals in the length direction of the half-opening spacing battens, steel belt positioning grooves are formed in the outer fixing battens in the length direction of the outer fixing battens, the bundling steel belt can be wrapped in the steel belt positioning grooves, the protection nails are of a half-square-shaped structure, the length of the protection nails is 10-20 mm larger than the width of the bundling steel belt, and the protection nails are of a half-square-shaped structure. The length of the nail claw is smaller than the thickness of the outer fixing batten; the protective nail can limit the bundled steel belt in the steel belt positioning groove so as to prevent the bundled steel belt from moving in the
