Problems solved by technology

There are many hidden dangers in pinching the oblique lug by hand. If the force is too large, the lead powder at the lower part of the lug will fall off. The end faces of the busbars are attached to each other, which affects the flow of lead liquid in casting soldering and leads to false welding, and there are defects of high labor intensity and low efficiency in manual pinching of oblique tabs

Embodiment Construction

[0018] Such as figure 1 , figure 2 As shown, the device of the present invention is a folded pole lug plate 1, and the folded pole lug plate 1 is provided with several positive pole lug positioning grooves 11, negative pole lug positioning grooves 12, two short side walls 121 of the negative pole lug positioning groove 12 The two long side walls 122 of the negative tab positioning groove 12 are inclined 15 to 25° toward the center of the slot, and the side walls of the negative tab positioning slot 12 are not inclined and extend to the bottom of the slot. The upper part of the ear positioning groove 12 is trumpet-shaped with the opening upward, and the lower part is rectangular.

[0019] The length of the upper opening of the positive tab positioning groove 11 is 2-4 mm longer than the total length of the positive tab row, and the width of the upper opening is 2-3 mm larger than the width of the positive tab; the length of the upper opening of the negative tab positioning gr...

Abstract

The invention discloses a pole-ear folding device for a cast-welding storage battery. The device is a pole-ear folding plate, and a plurality of anode ear positioning grooves and cathode ear positioning grooves are formed in the pole-ear folding plate. Two short side walls of each cathode ear positioning groove incline for 30-45 degrees to the center direction of the groove, and two long side walls of each cathode ear positioning groove incline for 15-25 degrees to the center direction of the groove. The pole-ear folding device has the advantages of simple structure and accurate pole-ear folding angle, is beneficial to cast-welding forming, and ensures the product quality. Moreover, the pole-ear folding device is easily operated, the labor intensity is alleviated, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of storage battery production, in particular to a device for folding tabs of cast-welded storage batteries. Background technique [0002] In the process of casting and welding the tabs of the battery, the tabs of the negative plate on the side are manually pinched to the inside at a slight angle, and then the busbars are cast and welded. There are many hidden dangers in pinching the oblique lug by hand. If the force is too large, the lead powder at the lower part of the lug will fall off. The end faces of the busbars are attached to each other, which affects the flow of the lead liquid in casting soldering and leads to false soldering, and the manual pinching of the oblique tabs also has the defects of high labor intensity and low efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tab-folding device for a cast-welded storage battery, which has ...
