The invention discloses a lateral joint welding and fixing device of a deformable ultra-thin metal structure and a method for welding the lateral structure using the same, and belongs to the field ofspecial welding, and particularly relates to a lateral joint welding and fixing device of a space-deployable ultra-thin metal structure and the method for welding the lateral structure using the same.The existing problem of no welding method for the lateral portion of the deformable ultra-thin metal structure is solved. The lateral joint welding and fixing device of the deformable ultra-thin metal structure comprises a joint fixing part and lateral fixing parts, the lateral fixing parts are arranged on two sides of the joint fixing part in a central symmetrical shape, and the lateral parts are connected with the joint fixing part in a bolt mode. The welding method comprises the steps that 1, the lateral joint welding and fixing device of the deformable ultra-thin metal structure is fixedto an automatic argon arc welding clamping platform; 2, an upper pressing block is separated from a lower pressing block; 3, locating and clamping are carried out; 4, welding is carried out; and 5, the welded deformable ultra-thin metal structure is taken out. The lateral joint welding and fixing device of the deformable ultra-thin metal structure and the method for welding the lateral structure using the same realize the reliable welding of the lateral portion of the structure. The lateral joint welding and fixing device of the deformable ultra-thin metal structure and the method for weldingthe lateral structure using the same is mainly used for lateral welding of the deformable ultra-thin metal structure.

A thin metal strip is produced by a single roll strip casting process, using a cooling roll, a tundish, and a molten metal remover. The cooling roll has an outer peripheral surface, on which it cools and solidifies molten metal while rotating. The tundish can accommodate the molten metal and supplies it onto the outer peripheral surface of the cooling roll. The molten metal remover is disposed downstream of the tundish in the rotating direction of the cooling roll with a gap A between the molten metal remover and an outer peripheral surface of the cooling roll, and removes a surface portion of the molten metal on the outer peripheral surface of the cooling roll to cut down the thickness of the molten metal to the width of the gap A.

The invention provides a shearing precise adjusting device for an ultrathin metal strip slitting machine. The shearing precise adjusting device comprises a fixed memorial gate and a movable memorial gate. A lower cutter shaft and an upper cutter shaft are arranged between the fixed memorial gate and the movable memorial gate, and disc blades are arranged on the lower cutter shaft and the upper cutter shaft. Height adjusting mechanisms are arranged on the fixed memorial gate and the movable memorial gate. The two height adjusting mechanisms are connected through a coupler. Screw rods are arranged at the lower portions of the height adjusting mechanisms, sliding blocks are arranged below the screw rods, guide pillars are arranged on the side faces of the screw rods, and self-lubricating bearings are arranged on the peripheries of the guide pillars. By means of the shearing precise adjusting device for the ultrathin metal strip slitting machine, the stability in the shearing process is ensured, the precise of the cutter shafts is greatly improved, jittering of the end faces of the cutter shafts is controlled to be within 0.002 mm, and therefore finished strips with high quality are obtained; and the technical problems the edge burrs of the narrow strips obtained after slitting are too large, and control over transverse bending (edge camber), corrugated edges (edge warping and longitudinal warping), torsion resistance, snakelike bending and the like is not ideal are solved.
