が知られている。There are a reciprocating method and a rotary method in the expanding method. The former reciprocating method is a means for vertically moving a die by a press machine and intermittently feeding a lead thin plate into the die for processing. It is known that the rotary method, in which a lead thin plate is continuously fed into a rotating cylindrical mold to process the latter, is more advantageous in improving the performance.

The lead thin plate 46 cut and machined vertically by the molds 41 and 42 having a
When expanding by 44 or the like, the node 50 of the lattice body is inclined so as to fall down in the developing direction,
Local torsion occurred in the center of the lattice bones 48 and 49.

いう問題を有していた。For this reason, when the rotary expanded lattice body is used for the positive electrode, the lattice bones are twisted due to the twisting of the lattice bones compared to the lattice body processed by the reciprocating method, so that the cross-sectional area of the lattice bones 48 and 49 is increased. As a result, the stress remains in this position, and as a result, the wire breaks due to the erosion of the lattice bone at an early stage, so the battery life is short, and it can be used only for the negative electrode without oxidation corrosion, and the lattice bone is twisted. There was a problem that the mechanical strength at the part also decreased.

度を向上するものである。In order to achieve this object, the present invention provides a rotary expandable die for processing a thin plate made of lead or a lead alloy by changing a cutting angle of a portion for forming a knot portion. In addition, it is possible to suppress the inclination of the knot portion, which causes twisting of the lattice bone, in the deployment direction, and to eliminate local torsion of the lattice bone. Then, it is possible to prevent the local cross-sectional area of the lattice bone from being reduced, thereby improving the corrosion resistance and the mechanical strength.

とができる。BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, a thin plate made of lead or a lead alloy is inserted between two rotating molds of a rotary-type expanding machine.
A lead-acid battery that uses a grid that has been subjected to a rotary expansion process and has a grid that has been developed in a mesh form and has no local twist in the grid bone has the advantage of having higher productivity than the reciprocating system. However, the mechanical strength of the lattice bone is large, and the life of the battery is long. Further, as described in the second aspect, the present invention can be applied to a grid of a positive electrode having oxidative corrosion.

The present invention can be easily implemented by not giving an inclination to fall down in the deployment direction.

There is a gap between the groove 4a of the upper blade 4a and the groove 4a of the lower disk-shaped saw blade 2a, and when a thin plate is sandwiched in this portion, the lattice is formed in a substantially semicircular shape downward without being elongated. It constitutes a nodule between the bone and a lattice bone formed in a substantially semicircular shape in the upward direction. This node corresponds to node 50 in FIG.
On the other hand, there is a flat surface 4b which is present in the concave portions of the disk-shaped saw blades 1a and 2a and is separated from the groove 4a by a distance from the convex portion 3, and has upper and lower disk-shaped saw blades 1a.
As a result of the rubbing of a and 2a, the thin plate at that portion is cut to generate a cut portion. It corresponds exactly to the cutting section 51 shown in FIG.
