Abstract

PURPOSE:To make the insertion work of pole plate lugs smooth by making the width of a slit corresponding to a bent section larger than those of other sections when bending a metal plate with slits to form a strap for an alkaline storage battery. CONSTITUTION:The required number of comb teeth-like notches 4 to be used as slits are provided on both sides of a band-like steel plate 3 by punching or the like, and the width B of a notch 4 at the bent section I is made larger than the widths A, C of other portions. Next, both sides of the central section 1a are bent downward in a channel shape, and further the vertical portion is bent outward in an L-shape to form a strap 1, which is used as a strap 12 for an alkaline storage battery, and lug sections 15 of pole plates 14 are inserted into individual slits and welded. Accordingly, correction due to irregular sizes of notched sections 4 during bend-machining is not required, the pole plate lugs can be smoothly inserted, and workability can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for manufacturing a strap for connecting a 44i board AY and a terminal to an alkaline storage battery.

As shown in FIG.
A comb-shaped slit 13 is provided in the strips 1 to 12 of the steel strip welded to 1, and the ears 15 of one or more electrode plates 14 are inserted into the slits 1 to 1. The ear portions 15 and 12 are welded together to form the electrode plate nY. This strap 12 is made by joining several strip-shaped steel roots together, cutting them or hammering them with a metal hammer to form comb-shaped slits, and then bending them.

However, as shown in FIG. 4 during the 117 bending process, the width B of the bent portion of the strap 12 to the slit 1 becomes narrower than the width Δ of the open end of the slit 13 or the width C of the rear end. There were many disadvantages, such as making it impossible to insert the electrode plate ears and making the work tedious and difficult.

Means for Solving the Problems The present invention involves bending a band-shaped metal plate, which has a plurality of slits with one end open, across the slits into an L-shape;
Insert the ear part of the electrode plate into the slit and weld.
[In the slap for other purposes, the band-shaped metal plate is
This method is characterized by bending the ribs 1 to 1 whose width at the bent portion is larger than the width at both ends, thereby making it possible to bend the ribs 1 to 1, which have a width dimension at the bent portion larger than the width dimension at both ends.
7) Prevents narrowing of the width of the slit at the bent portion and facilitates insertion of the electrode plate tab. This is l) with k'5.

EXAMPLE An example of the manufacturing method of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, 1 indicates slips 1 to 1, on both sides of which a plurality of slips 1 to 2 are provided at equal intervals.
Both sides of the central part 1a where the ball is welded are bent downward into a channel shape, and the hanging part of the groove is bent outward in a single-shape to form a vertical part 11) and a horizontal part 1C. ing. The above-mentioned sleeves 1 to 1 are cut from the water qz part 1C of the strap to the earth part of the vertical part 1b.To manufacture this strap 1, as shown in FIG.
A required number of comb-shaped notches 4 corresponding to the ribs L are provided at equal intervals on both sides of the slit L by one-stroke machining or the like. At this time, the width B of the cut 4 is the width △ of the open end of the horizontal part 1G and the vertical part 1b.
3 degrees larger than the width C of the rear end.The shape of this part is a diamond-shaped cut so that the bent part has the maximum width as shown in Figure 2 (a), or a similar cut. It is appropriate to use a combination of circular and linear cuts as shown in Figure (b), with the circular part V1 extending over the bent part (2). Next, the shape shown in FIG. 1 is completed by bending at right angles at the portions ① and ②.

[Effects of the Invention] Since the present invention uses the manufacturing method as described above, the width B of the bent portion of the slit after the bending process of the slit is equal to or slightly larger than the widths Δ and C of both ends. , there is no problem of the plate lug getting stuck when inserting the plate, there is no need to correct the strap notch, and the dimensional accuracy of the notch width is improved, making the process of inserting the plate lug easier.
Its industrial value is great.
