Description

Technical Field

[0001] The utility model relates to the field of bending jigs, and in particular to a nickel sheet bending jig. Background Art

[0002] Lithium batteries have gradually become the main power source for electric vehicles, mobile phones, laptops and other electronic products due to their high energy density, light weight and pollution-free characteristics. Lithium batteries have higher energy density and cycle life than traditional batteries such as lead-acid batteries and nickel-metal hydride batteries, and can provide a more stable and reliable power supply. In order to improve the performance and safety of lithium batteries, the batteries need to be connected.

[0003] The main connection methods on the market are welding and nickel sheet connection. Although welding connection is simple, it will cause oxidation on the battery surface, resulting in a decrease in battery performance. Nickel sheet connection connects the positive and negative electrodes inside the lithium battery to form a circuit. This method can reduce oxidation on the battery surface and improve the capacity and stability of the lithium battery, thereby improving its service life and efficiency. In addition, nickel sheets are also used as the pole ears of lithium batteries. When nickel sheets are used as pole ears, they need to be bent.

[0025] Through the implementation of the above technical solution, when in use, the nickel sheet to be bent is first placed under the pressure plate 9 and pushed in the direction of the limit baffle 10 until it is pushed against the side of the limit baffle 10, and the cylinder 7 is started to drive the movable plate 6, the vertical plate 3 and the pressure plate 9 to move downward as a whole, and the nickel sheet is stably clamped on the rectangular block 1 by the pressure plates 9 at both ends, thereby achieving stable clamping and accurate control of the length of the bent part, and finally, the bending block arranged above the right-angle groove 14 is used to press the bent part downward to achieve the bending of the nickel sheet. Since the nickel sheet has a certain thickness, when the bent part is in the process of bending, the edge of the nickel sheet will slightly squeeze the limit baffle 10. In order to overcome the horizontal displacement caused by the extrusion, the limit baffle 10 is set to be elastically connected with the vertical plate 15, and the limit baffle 10 is reset when the extrusion force disappears. In addition, by setting the transition position between the upper surface of the rectangular block 1 and the upper end of the right-angle groove 14 as the rounded corner 13, the corner position of the bent nickel sheet can be made to be the rounded corner 13 for a smooth transition.
