Description of the Related Art In recent years, in order to improve the productivity of lead-acid battery grids, from the production by the casting method, a material obtained by rolling lead or a lead alloy into a thin sheet by rolling or the like is subjected to an expanding process, and is continuously performed. Expanding methods that can produce grids have become mainstream. The expanding method is roughly classified into a reciprocating method and a rotary method as described in JP-B-60-29573 and JP-B-8-2568285.

That is, in the first step, a plurality of slits are formed in the sheet-like lead alloy in the longitudinal direction of the sheet, and at the same time, the linear portions serving as lattice bones are mutually reversed in a direction substantially perpendicular to the sheet surface. It is stretched and formed into a curved shape. At this time, as shown in FIG. 3, a roll as shown in FIG. 2 in which a plurality of disc-shaped cutters in which convex portions are arranged at a predetermined pitch on the circumferential portion as shown in FIG. When the slits are formed and the convex portions are pressed against the sheet at the same time, the linear portions serving as lattice bones are opposite to each other in a direction substantially perpendicular to the sheet surface. It is stretched and formed in a curved shape.

The disk-shaped cutter shown in FIG. 3 is partially enlarged, and a plurality of disk-shaped cutters are combined as shown in FIG.
And The lead alloy sheet 3 in an unformed state is passed between the rolls 1 and 2 to form a formed lead alloy sheet 4. This is because the flat portion 6 provided on the disk-shaped cutter 5 of the roll 1 meshes with the same flat portion 6 of the opposing roll 2 so that every other slit can be provided in the width direction. Can be formed. At the same time, when the convex portion 7 presses the linear portion, the linear portion is formed so as to extend in a direction substantially perpendicular to the sheet surface in a curved shape opposite to each other. In addition, between two slits adjacent in the width direction is a knot. Also, between the convex portions arranged at a predetermined pitch on the circumferential portion of the disk-shaped cutter, relief portions 8 inclined so as to be thin in the circumferential direction are provided at regular intervals on the left and right sides of the circumferential surface.

ラックや線状部９の断線が発生しやすい。FIG. 4 shows a lead sheet formed by a conventional rotary method. When the sheet 4 is stretched in the second step, since the linear portions 9 and the knot portions 10 are formed uniformly, as shown in FIG. 5, the mesh of the developed portions is formed uniformly. As a result, cracks and breaks in the linear portions 9 are likely to occur around the nodules 10 on the upper side where the ears 11 of the lattice body with a large load are located.

まっていた。In particular, lead sheet alloys for the purpose of prolonging the service life of lead-acid batteries in recent years have improved mechanical properties such as material strength, but cracks or cracks occur when the grid is formed as described above. Disconnection sometimes occurred. This is because the mesh-like developed part has low bending and tensile properties, so it is prone to bone breakage, and when used as a positive electrode grid of a lead-acid battery, it promotes oxidative corrosion from cracks generated during deployment. The life of lead-acid batteries has also been shortened.
